+# Samsung Inner Source Governance
+
+The *Samsung Inner Source Governance*(the "Governance") sets forth the responsibilities and procedures for technical contribution to, and oversight of, the *Samsung Inner Source Community*(the "Community") within Samsung Electronics. Contributors to the Community **MUST** comply with the terms of the governance as well as any applicable policies of Samsung Electronics.
+
+All the Communities under the *Samsung Inner Source Program* **MUST** inherit this Governance and each Community is allowed to create its own Community Rule but only as a type of ADDON tailoring. Additionally which **SHOULD** be announced each project wiki page with a title named 'Community Rules' and should be described in [Project List] page of your project in this portal.
+
+## 1. Guideline for Operation
+Samsung Inner Source Program uses an **OPEN ENVIRONMENT** which the CODE(Github enterprise version) as a source forge.
+The baseline of Inner Source Program repository is **PUBLIC**. If you have any specific reason to make it PRIVATE, you SHOULD make a request via Inner Source Portal. However the request COULD not be accepted if it doesn't have obvious reasons.
+
+## 2. Roles and Responsibilities
+The Samsung Inner Source Community Recognizes the following formal roles: a Developer, a Committer and a Maintainer.
+Informally, the Community may organize itself and give rights and responsibilities to the necessary people to achieve its goals.
+
+1. A Developer
+
+ A Developer is anyone who wishes to contribute to the project, at any level. Developers are granted the following right to:
+ - Contribute code, documentation, translations, artwork, etc,.
+ - Report defects(bugs) and suggestions for enhancements;
+ - Participate in the process of reviewing contributions by others;
+ - Initiate and participate in discussions in communication channels.
+
+ Developers are required to:
+ - Abide by decisions, once made. They are welcome to provide new, relevant information to reopen decisions;
+ - Assume responsibility for issues and bugs introduced by one's own contributions;
+ - Respect the 'Rules of Community'(see below);
+ - Provide constructive advices whenever participating in discussions and in the review of contributions.
+
+2. A Committer
+
+ A Committer is a Developer who is also responsible for the maintenance of a particular area of code or of a source code repository. Committers have the following rights and responsibilities, in addition to those listed for Developers:
+ - Right to set goals for the short and medium terms for the repository being maintained;
+ - Responsibility to ensure all contributions to the repository have been reviewed within reasonable time;
+ - Responsibility to monitor discussions in the Community.
+
+3. A Maintainer
+
+ A Maintainer is a Developer who is also responsible for knowing, directing and anticipating the needs of a given repository. Maintainers have the following rights and responsibilities, in addition to those listed for Committers:
+ - Right to set the overall organization of the source code in the repository;
+ - Right and responsibility to lead the feature development discussion;
+ - Responsibility to ensure the quality of the code to expected levels;
+ - Responsibility to participate in the quality verification and release process, when those happen.
+ - Responsibility of a **representative of the Community**;
+ - Maximum 2 Maintainers are allowed per Community.
+
+ A Maintainer is not a mandatory role of Samsung Inner Source Governance. When the Community decide to go without the role title of a Maintainers, one of the Committer of the Community SHOULD take the written roles and responsibilities of a Maintainer in Samsung Inner Source Governance.
+
+4. A Benevolent-Leader
+
+ A Benevolent-Leader is a member of the Community who has the final saying in the case of disputes. This is a model followed by many successful Open Source projects, and they are sometimes called the "benevolent dictator". The Benevolent-Leader has the following responsibilities:
+ - Govern Samsung Inner Source Program;
+ - Make calm controversy in Communities and a Program itself.
+
+ A Benevolent-Leader refers to the role, not a person.
+
+5. An Administrator
+
+ An Administrator is a member who help operate and gear to healthy Samsung Inner Source Program. Samsung Inner Source Portal is operated by the Administrator.
+
+6. Selection of Committers and Maintainers
+
+ A candidate for the Committer role should be one of the Developers who has submitted at least 10 non-trivial patches in that repository and has shown characteristics consistent with the requirements of the Committer role. To be a candidate for the Committer or the Maintainer, a Developer can self-nominate with proper evidences.
+
+ The selection process SHOULD be archived by consensus of the Developers active, Committers and Maintainers in that repository. If consensus cannot be achieved, the Benevolent-Leader will make the decision and all decisions MUST be ratified by the Benevolent-Leader.
+
+7. Revocation of Committers/Maintainers status
+
+ A Maintainer or a Committer who intentionally abuses his review privilege may have it temporarily suspended on the request of other Committers or Maintainers. Committers and Maintainers not including the person under consideration should discuss on the revocation of the person. If consensus cannot be reached, the Benevolent-Leader will make the decision and all decisions MUST be ratified by the Benevolent-Leader.
+
+## 3. Rules of Community
+
+1. Samsung Inner Source Program aims for OPEN COLLABORATION.
+
+ 1) Egalitarian, Every contributors who is willing to help a project should be welcome.
+ 2) Contributions to projects should be judged meritocracy based on the value they bring to the project. For transparency, all the merits SHOULD be come with **OPEN COMMUNICATION** (decisions should be discussed publicly).
+ 3) A Community is an individual organizational unit.
+
+ All Community members must abide by rules of common sense, civility and good neighborliness. Frank discussion is welcomed and encouraged with the goal of arriving at the best technical solution possible. Discussion about the people participating in development is not welcomed and ad hominem attacks MUST not be tolerated.
+
+2. All Community members must adhere to these simple rules:
+
+ 1) Respect and acknowledge all contributions, suggestions and comments from the Community;
+ 2) Listen and be open to all opinions, which are subject to open discussion;
+ 3) Help each other and the other developers;
+ 4) Assume people mean well;
+ 5) **Be humble and bold**.
+
+3. Lazy Consensus and Silent Consent
+
+ 1) Lazy Consensus means that developers may proceed with work when they have a reason to believe that other Developers in the Community will agree with the direction, and need not stop to initiate unnecessary discussions about the work. In this case, they should publish their work rapidly (that is, merge proposals to version control) to allow others to raise objections when there are any. When the developer is not sure there will be consensus, they should raise a proposal on the appropriate communication channels. The Silent Consent principle will apply in this case.
+ 2) Silent Consent means that those who do not offer a reasoned alternative in course of the discussion implicitly agree with the proposal.
+ 3) These principles are valid for **OPEN DISCUSSIONS** in the Github Issues and/or the Primary Communication Channel of the Community. Consensus reached in other ways (such as face-to face discussions or communication on other channels) are to be considered unapproved proposals until submitted to the relevant Github Issues and/or the Primary Communication Channel of the Community. Thus giving dissenting options the opportunity to be voiced.
+
+4. Decision Making in the Samsung Inner Source Community
+
+ 1) Decisions are made always at the lowest level possible that is applicable for the decision in a question.
+ 2) Individual Developers are making decisions every time they submit changes.
+ 3) two or more Developers also make decisions when participating in an **OPEN DISCUSSION**. Their arguments in why a given decision should be made are part of the consensus that needs to be reached for the decision. Any of opinions **SHOULD NOT** be disregarded.
+ 4) If those Developers cannot agree and reach consensus on a decision, then the Benevolent-Leader WOULD mediates the situation, avoiding stalemates. Arbitration COULD made by voting of relevant Community members on the issue.
+ - Decisions affecting a project are made by community members of the project.
+ - Decisions that overlap more than one project are made in conjunction by community members of related projects.

- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 59 Temple Place - Suite 330, Boston, MA
- 02111-1307, USA.
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-\f
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-\f
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-\f
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-\f
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
- END OF TERMS AND CONDITIONS
-\f
- Appendix: How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) 19yy <name of author>
-
- This program is free software; you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation; either version 2 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program; if not, write to the Free Software
- Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) 19yy name of author
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program
- `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
- <signature of Ty Coon>, 1 April 1989
- Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Library General
-Public License instead of this License.

+# Introduction
+The development of node.js has created a platform-independent JavaScript runtime environment, where Web developers can run their JavaScript code outside a Web browser. Benefits of using node.js for a Web app developer when creating Web apps includes, but not limited to, reusing already known Web development knowledge, using only JavaScript on both server and client sides, and so on. While node.js provides the state-of-the-art performance and a wide range of supporting libraries, it is not suitable for memory-constrained devices such as TVs, and consumer electronics. This is because node.js is designed to provide better performance by efficiently using a large amount of memory. This goal of node.js conflicts with the goal of optimizing memory usage on these devices in memory-constrained environments. Adopting node.js to these memory-constrained devices is challenging, because the design and implementation of node.js conflict with the physically small amount of memory shipped with these devices.
+
+In this document, we introduce lightweight node.js (LWNode) whose aim is to provide a JavaScript runtime environment for memory-constrained devices. Some advantages of LWNode are as follows:
+
+* LWNode is a memory-optimized node.js for Tizen-based memory-constrained devices such as TVs. Compared to stock node.js, LWNode consumes 30% less amount of memory on TV.
+* Supports a wide range of node.js modules
+
+LWNode is already shipped to the following Samsung products.
+
+* Provides a runtime environment for Spotify on TV
+
+# Expected Values
+LWNode can easily provide a JavaScript runtime environment in a memory-efficient way. In particular, LWNode
+
+* Provides a Tizen-optimized, and memory-efficient JavaScript runtime environment
+* Provides a set of Tizen-specific Web Device APIs
+
+# Requirements
+LWNode is designed to meet the following requirements.
+
+* Functional requirements
+ - Supports Spotify on TV
+ - Supports a set of node.js modules defined in Appendix 1
+ - Supports a set of Tizen Web Device APIs
+* Non-functional requirements
+ - Customizable for various business requirements and target devices
+ - Low memory usage and small memory footprints
+
+# Target Applications
+LWNode supports the following devices.
+
+* Tizen-based devices such as TVs, speakers, etc.
+
+# Appendix 1: Supporting Modules
+A list of supporting modules are described in [spec.md](spec.md).

+# Doxygen Awesome
+
+[](https://github.com/jothepro/doxygen-awesome-css/releases/latest)
+[](https://github.com/jothepro/doxygen-awesome-css/blob/main/LICENSE)
+
+<div style="filter: drop-shadow(0px 3px 15px rgba(0,0,0,0.25))">
+
+[](https://jothepro.github.io/doxygen-awesome-css/)
+
+</div>
+<br>
+
+**Doxygen Awesome** is a custom **CSS theme for doxygen** html-documentation with lots of customization parameters.
+
+## Motivation
+
+I really like how the doxygen html-documentation is structured! But IMHO it looks a bit outdated.
+
+This theme is an attemt to update the visuals of doxygen without changing it's overall layout too much.
+
+## Features
+
+- 🌈 Clean, modern design
+- 🚀 Heavily customizable by adjusting CSS-variables
+- 🧩 No changes to the HTML structure of Doxygen required
+- 📱 Improved mobile usability
+- 🌘 Dark mode support!
+- 🥇 Works best with **doxygen 1.9.1** or **1.9.2**
+
+## Installation
+
+Copy the `css` files from this repository into your project or add this repository as submodule and check out the latest release:
+
+```bash
+git submodule add https://github.com/jothepro/doxygen-awesome-css.git
+cd doxygen-awesome-css
+git checkout v1.5.0
+```
+
+Then make the option `HTML_EXTRA_STYLESHEET` in your Doxyfile point to the `css` files:
+
+```
+# Doxyfile
+# ...
+HTML_EXTRA_STYLESHEET = doxygen-awesome-css/doxygen-awesome.css
+```
+
+### Variants
+
+There is two variants of the theme.
+
+
+
+1. **Base theme**:
+```
+# Doxyfile
+GENERATE_TREEVIEW = YES # optional. Also works without treeview
+HTML_EXTRA_STYLESHEET = doxygen-awesome-css/doxygen-awesome.css
+```
+
+2. **Sidebar-only theme** (experimental):
+```
+# Doxyfile
+GENERATE_TREEVIEW = YES # required!
+HTML_EXTRA_STYLESHEET = doxygen-awesome-css/doxygen-awesome.css doxygen-awesome-css/doxygen-awesome-sidebar-only.css
+```
+
+### Dark Mode Toggle (Experimental)
+
+The theme comes with an experimental feature that adds a button to enable and disable the dark theme variant manually.
+
+It requires customizations in both the header & footer html template.
+
+1. Create default header & footer templates:
+ ```bash
+ doxygen -w html header.html footer.html delete_me.css
+ ```
+
+2. Reference the required resources in your `Doxyfile`:
+ ```
+ # Include the required Javascript
+ HTML_EXTRA_FILES = doxygen-awesome-css/doxygen-awesome-darkmode-toggle.js
+
+ # Add the additional CSS. This is ONLY required for the sidebar-only theme variant!
+ HTML_EXTRA_STYLESHEET = doxygen-awesome-css/doxygen-awesome.css \
+ doxygen-awesome-css/doxygen-awesome-sidebar-only.css \
+ doxygen-awesome-css/doxygen-awesome-sidebar-only-darkmode-toggle.css
+
+ # set custom header & footer files generated in previous step
+ HTML_HEADER = header.html
+ HTML_FOOTER = footer.html
+ ```
+
+3. In `header.html`, include `doxygen-awesome-darkmode-toggle.js` at the end of the `<head>`:
+ ```html
+ <html>
+ <head>
+ <!-- ... other metadata & script includes ... -->
+ <script type="text/javascript" src="$relpath^doxygen-awesome-darkmode-toggle.js"></script>
+ </head>
+ <body>
+ ```
+4. In `footer.html`, initialize the `doxygen-awesome-dark-mode-toggle` element at the end of the `<body>`:
+ ```html
+ <!-- ... -->
+ <script type="text/javascript">
+ // script for doxygen 1.9.1
+ $(function() {
+ $(document).ready(function(){
+ toggleButton = document.createElement('doxygen-awesome-dark-mode-toggle')
+ toggleButton.title = "Toggle Light/Dark Mode"
+ document.getElementById("MSearchBox").parentNode.appendChild(toggleButton)
+ })
+ })
+ </script>
+ </body>
+ </html>
+ ```
+ **Attention**: In Doxygen 1.9.2 the searchbox and it's siblings are deleted on every resize, which is why the toggle button has to be re-added every time:
+ ```js
+ $(function() {
+ toggleButton = document.createElement('doxygen-awesome-dark-mode-toggle')
+ toggleButton.title = "Toggle Light/Dark Mode"
+
+ $(document).ready(function(){
+ document.getElementById("MSearchBox").parentNode.appendChild(toggleButton)
+ })
+ $(window).resize(function(){
+ document.getElementById("MSearchBox").parentNode.appendChild(toggleButton)
+ })
+ })
+ ```
+
+## Examples
+
+- Sidebar-Only theme: [Documentation of this repository](https://jothepro.github.io/doxygen-awesome-css/)
+- Base theme: [libsl3](https://a4z.github.io/libsl3/)
+
+
+## Configuration
+
+### CSS Variables
+
+This theme is highly customizable because a lot of things are parameterized with CSS variables. The following
+list of parameters is not complete! You can easily modify any variable with the developer tools of your browser to find
+out what it does.
+
+To customize the existing theme, add your own `custom.css` and overwrite the variables there:
+```
+HTML_EXTRA_STYLESHEET = doxygen-awesome-theme/doxygen-awesome.css custom.css
+```
+
+```css
+/* custom.css */
+html {
+ /* define light-mode variable overrides here */
+}
+
+@media (prefers-color-scheme: dark) {
+ html:not(.light-mode) {
+ /* define dark-mode variable overrides here if you DON'T use doxygen-awesome-darkmode-toggle.js */
+ }
+}
+
+html.dark-mode {
+ /* define dark-mode variable overrides here if you DO use doxygen-awesome-darkmode-toggle.js */
+}
+```
+
+| Parameter | Default (Light) | Default (Dark) |
+| :-------------------------------- | :---------------------------------------------------------- | ----------------------------------------------------------- |
+| **Color Scheme**:<br>primary theme color. This will affect the entire websites color scheme: links, arrows, labels, ... |||
+| `--primary-color` | <span style="background:#1779c4;color:white">#1779c4</span> | <span style="background:#1982d2;color:white">#1982d2</span> |
+| `--primary-dark-color` | <span style="background:#00559f;color:white">#00559f</span> | <span style="background:#5ca8e2;color:white">#5ca8e2</span> |
+| `--primary-light-color` | <span style="background:#7aabd6;color:black">#7aabd6</span> | <span style="background:#4779ac;color:white">#4779ac</span> |
+| `--primary-lighter-color` | <span style="background:#cae1f1;color:black">#cae1f1</span> | <span style="background:#191e21;color:white">#191e21</span> |
+| `--primary-lightest-color` | <span style="background:#e9f1f8;color:black">#e9f1f8</span> | <span style="background:#191a1c;color:white">#191a1c</span> |
+| **Spacing:**<br>default spacings. Most ui components reference these values for spacing, to provide uniform spacing on the page. |||
+| `--spacing-small` | `5px` | |
+| `--spacing-medium` | `10px` | |
+| `--spacing-large` | `16px` | |
+| **Border Radius**:<br>border radius for all rounded ui components. Will affect many components, like dropdowns, memitems, codeblocks, ... |||
+| `--border-radius-small` | `4px` | |
+| `--border-radius-medium` | `6px` | |
+| `--border-radius-large` | `8px` | |
+| **Content Width**:<br>The content is centered and constrained in its width. To make the content fill the whole page, set the following variable to `auto`. |||
+| `--content-maxwidth` | `1000px` | |
+| **Code Fragment Colors**:<br>Color-Scheme of multiline codeblocks |||
+| `--fragment-background` | <span style="background:#282c34;color:white">#282c34</span> | |
+| `--fragment-foreground` | <span style="background:#fff;wolor:black">#fff</span> | |
+| **Arrow Opacity**:<br>By default the arrows in the sidebar are only visible on hover. You can override this behaviour so they are visible all the time. |||
+| `--side-nav-arrow-opacity` | `0` | |
+| `--side-nav-arrow-hover-opacity` | `0.9` | |
+| **Darkmode Toggle Icon**:<br>If you have enabled the darkmode toggle button, you can define the icon that is shown for the current mode. |||
+| `--darkmode-toggle-button-icon` | ☀️ | 🌛 |
+| ...and many more |||
+

+
+### Doxygen generator
+
+The theme overrides most colors with the `--primary-color-*` variables.
+
+But there is a few small images and graphics that the theme cannot adjust or replace. To make these blend in better with
+the rest, it is recommended to adjust the [doxygen color settings](https://www.doxygen.nl/manual/customize.html#minor_tweaks_colors)
+to something that matches the chosen color-scheme.
+
+For the default color-scheme, these values work out quite well:
+
+```
+# Doxyfile
+HTML_COLORSTYLE_HUE = 209
+HTML_COLORSTYLE_SAT = 255
+HTML_COLORSTYLE_GAMMA = 113
+```
+
+## Browser support
+
+Tested with
+
+- Chrome 91, Chrome 91 for Android, Chrome 87 for iOS
+- Safari 14, Safari for iOS 14
+- Firefox 89, Firefox Daylight 89 for Android, Firefox Daylight 33 for iOS
+
+## Tips & Tricks
+
+### Class Diagrams with Graphviz
+
+To get the best looking class diagrams for your documentation, generate them with Graphviz as vector graphics with transparent background:
+
+```
+# Doxyfile
+HAVE_DOT = YES
+DOT_IMAGE_FORMAT = svg
+DOT_TRANSPARENT = YES
+```
+
+### Share your own theme customizations
+
+If you customized the theme with custom colors, spacings, font-sizes, etc. and you want to share your creation with others, you can to this [here](https://github.com/jothepro/doxygen-awesome-css/discussions/13).
+
+I am always curious to learn about how you made the theme look even better!
+
+
+## Credits
+
+This theme is heavily inspired by the beautiful [vuepress](https://vuepress.vuejs.org/) static site generator default theme!

+# Internal documentation of LWNode.js
+
+These flags and variables are for LWNode.js core development usage only. Do not use them in your own applications.
+
+## CLI
+
+### Flags
+
+#### `--internal-log`
+
+If the `--internal-log` flag is specified or the `LWNODE_INTERNAL_LOG` environment variable is set to 1, LWNode will print internal logs in release build.
+
+#### `--trace-call[=[-]trace id[,<trace id>]]`
+
+If the `--trace-call` flag is specified or the `LWNODE_TRACE_CALL` environment variable is set to trace ids, LWNode will print trace call logs in debug build. Setting trace id with `-` will negate printing trace logs for the specific id.
+
+```shell
+--trace-call=COMMON,ISOLATE
+
+# or
+
+export LWNODE_TRACE_CALL=COMMON,ISOLATE
+```
+
+### Environment variables
+
+#### `LWNODE_INTERNAL_LOG`
+
+Refer to the description above.
+
+#### `LWNODE_TRACE_CALL`
+
+Refer to the description above.
+
+#### `LWNODE_RUNNING_ON_TESTS`
+
+If the `LWNODE_RUNNING_ON_TESTS` environment variable is set to 1, LWNode will ignore comparing error messages in detail while using `assert.throw` and similars. This is used as default when using `tools/test.py`. Please refer to https://github.sec.samsung.net/lws/node-escargot/issues/1002 for more information.

+# Errors
+
+<!--introduced_in=v4.0.0-->
+<!--type=misc-->
+
+Applications running in Node.js will generally experience four categories of
+errors:
+
+* Standard JavaScript errors such as {EvalError}, {SyntaxError}, {RangeError},
+ {ReferenceError}, {TypeError}, and {URIError}.
+* System errors triggered by underlying operating system constraints such
+ as attempting to open a file that does not exist or attempting to send data
+ over a closed socket.
+* User-specified errors triggered by application code.
+* `AssertionError`s are a special class of error that can be triggered when
+ Node.js detects an exceptional logic violation that should never occur. These
+ are raised typically by the `assert` module.
+
+All JavaScript and system errors raised by Node.js inherit from, or are
+instances of, the standard JavaScript {Error} class and are guaranteed
+to provide *at least* the properties available on that class.
+
+## Error propagation and interception
+
+<!--type=misc-->
+
+Node.js supports several mechanisms for propagating and handling errors that
+occur while an application is running. How these errors are reported and
+handled depends entirely on the type of `Error` and the style of the API that is
+called.
+
+All JavaScript errors are handled as exceptions that *immediately* generate
+and throw an error using the standard JavaScript `throw` mechanism. These
+are handled using the [`try…catch` construct][try-catch] provided by the
+JavaScript language.
+
+```js
+// Throws with a ReferenceError because z is not defined.
+try {
+ const m = 1;
+ const n = m + z;
+} catch (err) {
+ // Handle the error here.
+}
+```
+
+Any use of the JavaScript `throw` mechanism will raise an exception that
+*must* be handled using `try…catch` or the Node.js process will exit
+immediately.
+
+With few exceptions, _Synchronous_ APIs (any blocking method that does not
+accept a `callback` function, such as [`fs.readFileSync`][]), will use `throw`
+to report errors.
+
+Errors that occur within _Asynchronous APIs_ may be reported in multiple ways:
+
+* Most asynchronous methods that accept a `callback` function will accept an
+ `Error` object passed as the first argument to that function. If that first
+ argument is not `null` and is an instance of `Error`, then an error occurred
+ that should be handled.
+
+<!-- eslint-disable no-useless-return -->
+ ```js
+ const fs = require('fs');
+ fs.readFile('a file that does not exist', (err, data) => {
+ if (err) {
+ console.error('There was an error reading the file!', err);
+ return;
+ }
+ // Otherwise handle the data
+ });
+ ```
+
+* When an asynchronous method is called on an object that is an
+ [`EventEmitter`][], errors can be routed to that object's `'error'` event.
+
+ ```js
+ const net = require('net');
+ const connection = net.connect('localhost');
+
+ // Adding an 'error' event handler to a stream:
+ connection.on('error', (err) => {
+ // If the connection is reset by the server, or if it can't
+ // connect at all, or on any sort of error encountered by
+ // the connection, the error will be sent here.
+ console.error(err);
+ });
+
+ connection.pipe(process.stdout);
+ ```
+
+* A handful of typically asynchronous methods in the Node.js API may still
+ use the `throw` mechanism to raise exceptions that must be handled using
+ `try…catch`. There is no comprehensive list of such methods; please
+ refer to the documentation of each method to determine the appropriate
+ error handling mechanism required.
+
+The use of the `'error'` event mechanism is most common for [stream-based][]
+and [event emitter-based][] APIs, which themselves represent a series of
+asynchronous operations over time (as opposed to a single operation that may
+pass or fail).
+
+For *all* [`EventEmitter`][] objects, if an `'error'` event handler is not
+provided, the error will be thrown, causing the Node.js process to report an
+uncaught exception and crash unless either: The [`domain`][domains] module is
+used appropriately or a handler has been registered for the
+[`'uncaughtException'`][] event.
+
+```js
+const EventEmitter = require('events');
+const ee = new EventEmitter();
+
+setImmediate(() => {
+ // This will crash the process because no 'error' event
+ // handler has been added.
+ ee.emit('error', new Error('This will crash'));
+});
+```
+
+Errors generated in this way *cannot* be intercepted using `try…catch` as
+they are thrown *after* the calling code has already exited.
+
+Developers must refer to the documentation for each method to determine
+exactly how errors raised by those methods are propagated.
+
+### Error-first callbacks
+
+<!--type=misc-->
+
+Most asynchronous methods exposed by the Node.js core API follow an idiomatic
+pattern referred to as an _error-first callback_. With this pattern, a callback
+function is passed to the method as an argument. When the operation either
+completes or an error is raised, the callback function is called with the
+`Error` object (if any) passed as the first argument. If no error was raised,
+the first argument will be passed as `null`.
+
+```js
+const fs = require('fs');
+
+function errorFirstCallback(err, data) {
+ if (err) {
+ console.error('There was an error', err);
+ return;
+ }
+ console.log(data);
+}
+
+fs.readFile('/some/file/that/does-not-exist', errorFirstCallback);
+fs.readFile('/some/file/that/does-exist', errorFirstCallback);
+```
+
+The JavaScript `try…catch` mechanism **cannot** be used to intercept errors
+generated by asynchronous APIs. A common mistake for beginners is to try to
+use `throw` inside an error-first callback:
+
+```js
+// THIS WILL NOT WORK:
+const fs = require('fs');
+
+try {
+ fs.readFile('/some/file/that/does-not-exist', (err, data) => {
+ // Mistaken assumption: throwing here...
+ if (err) {
+ throw err;
+ }
+ });
+} catch (err) {
+ // This will not catch the throw!
+ console.error(err);
+}
+```
+
+This will not work because the callback function passed to `fs.readFile()` is
+called asynchronously. By the time the callback has been called, the
+surrounding code, including the `try…catch` block, will have already exited.
+Throwing an error inside the callback **can crash the Node.js process** in most
+cases. If [domains][] are enabled, or a handler has been registered with
+`process.on('uncaughtException')`, such errors can be intercepted.
+
+## Class: `Error`
+
+<!--type=class-->
+
+A generic JavaScript {Error} object that does not denote any specific
+circumstance of why the error occurred. `Error` objects capture a "stack trace"
+detailing the point in the code at which the `Error` was instantiated, and may
+provide a text description of the error.
+
+All errors generated by Node.js, including all system and JavaScript errors,
+will either be instances of, or inherit from, the `Error` class.
+
+### `new Error(message)`
+
+* `message` {string}
+
+Creates a new `Error` object and sets the `error.message` property to the
+provided text message. If an object is passed as `message`, the text message
+is generated by calling `message.toString()`. The `error.stack` property will
+represent the point in the code at which `new Error()` was called. Stack traces
+are dependent on [V8's stack trace API][]. Stack traces extend only to either
+(a) the beginning of *synchronous code execution*, or (b) the number of frames
+given by the property `Error.stackTraceLimit`, whichever is smaller.
+
+### `Error.captureStackTrace(targetObject[, constructorOpt])`
+
+* `targetObject` {Object}
+* `constructorOpt` {Function}
+
+Creates a `.stack` property on `targetObject`, which when accessed returns
+a string representing the location in the code at which
+`Error.captureStackTrace()` was called.
+
+```js
+const myObject = {};
+Error.captureStackTrace(myObject);
+myObject.stack; // Similar to `new Error().stack`
+```
+
+The first line of the trace will be prefixed with
+`${myObject.name}: ${myObject.message}`.
+
+The optional `constructorOpt` argument accepts a function. If given, all frames
+above `constructorOpt`, including `constructorOpt`, will be omitted from the
+generated stack trace.
+
+The `constructorOpt` argument is useful for hiding implementation
+details of error generation from the user. For instance:
+
+```js
+function MyError() {
+ Error.captureStackTrace(this, MyError);
+}
+
+// Without passing MyError to captureStackTrace, the MyError
+// frame would show up in the .stack property. By passing
+// the constructor, we omit that frame, and retain all frames below it.
+new MyError().stack;
+```
+
+### `Error.stackTraceLimit`
+
+* {number}
+
+The `Error.stackTraceLimit` property specifies the number of stack frames
+collected by a stack trace (whether generated by `new Error().stack` or
+`Error.captureStackTrace(obj)`).
+
+The default value is `10` but may be set to any valid JavaScript number. Changes
+will affect any stack trace captured *after* the value has been changed.
+
+If set to a non-number value, or set to a negative number, stack traces will
+not capture any frames.
+
+### `error.code`
+
+* {string}
+
+The `error.code` property is a string label that identifies the kind of error.
+`error.code` is the most stable way to identify an error. It will only change
+between major versions of Node.js. In contrast, `error.message` strings may
+change between any versions of Node.js. See [Node.js error codes][] for details
+about specific codes.
+
+### `error.message`
+
+* {string}
+
+The `error.message` property is the string description of the error as set by
+calling `new Error(message)`. The `message` passed to the constructor will also
+appear in the first line of the stack trace of the `Error`, however changing
+this property after the `Error` object is created *may not* change the first
+line of the stack trace (for example, when `error.stack` is read before this
+property is changed).
+
+```js
+const err = new Error('The message');
+console.error(err.message);
+// Prints: The message
+```
+
+### `error.stack`
+
+* {string}
+
+The `error.stack` property is a string describing the point in the code at which
+the `Error` was instantiated.
+
+```console
+Error: Things keep happening!
+ at /home/gbusey/file.js:525:2
+ at Frobnicator.refrobulate (/home/gbusey/business-logic.js:424:21)
+ at Actor.<anonymous> (/home/gbusey/actors.js:400:8)
+ at increaseSynergy (/home/gbusey/actors.js:701:6)
+```
+
+The first line is formatted as `<error class name>: <error message>`, and
+is followed by a series of stack frames (each line beginning with "at ").
+Each frame describes a call site within the code that lead to the error being
+generated. V8 attempts to display a name for each function (by variable name,
+function name, or object method name), but occasionally it will not be able to
+find a suitable name. If V8 cannot determine a name for the function, only
+location information will be displayed for that frame. Otherwise, the
+determined function name will be displayed with location information appended
+in parentheses.
+
+Frames are only generated for JavaScript functions. If, for example, execution
+synchronously passes through a C++ addon function called `cheetahify` which
+itself calls a JavaScript function, the frame representing the `cheetahify` call
+will not be present in the stack traces:
+
+```js
+const cheetahify = require('./native-binding.node');
+
+function makeFaster() {
+ // `cheetahify()` *synchronously* calls speedy.
+ cheetahify(function speedy() {
+ throw new Error('oh no!');
+ });
+}
+
+makeFaster();
+// will throw:
+// /home/gbusey/file.js:6
+// throw new Error('oh no!');
+// ^
+// Error: oh no!
+// at speedy (/home/gbusey/file.js:6:11)
+// at makeFaster (/home/gbusey/file.js:5:3)
+// at Object.<anonymous> (/home/gbusey/file.js:10:1)
+// at Module._compile (module.js:456:26)
+// at Object.Module._extensions..js (module.js:474:10)
+// at Module.load (module.js:356:32)
+// at Function.Module._load (module.js:312:12)
+// at Function.Module.runMain (module.js:497:10)
+// at startup (node.js:119:16)
+// at node.js:906:3
+```
+
+The location information will be one of:
+
+* `native`, if the frame represents a call internal to V8 (as in `[].forEach`).
+* `plain-filename.js:line:column`, if the frame represents a call internal
+ to Node.js.
+* `/absolute/path/to/file.js:line:column`, if the frame represents a call in
+ a user program, or its dependencies.
+
+The string representing the stack trace is lazily generated when the
+`error.stack` property is **accessed**.
+
+The number of frames captured by the stack trace is bounded by the smaller of
+`Error.stackTraceLimit` or the number of available frames on the current event
+loop tick.
+
+## Class: `AssertionError`
+
+* Extends: {errors.Error}
+
+Indicates the failure of an assertion. For details, see
+[`Class: assert.AssertionError`][].
+
+## Class: `RangeError`
+
+* Extends: {errors.Error}
+
+Indicates that a provided argument was not within the set or range of
+acceptable values for a function; whether that is a numeric range, or
+outside the set of options for a given function parameter.
+
+```js
+require('net').connect(-1);
+// Throws "RangeError: "port" option should be >= 0 and < 65536: -1"
+```
+
+Node.js will generate and throw `RangeError` instances *immediately* as a form
+of argument validation.
+
+## Class: `ReferenceError`
+
+* Extends: {errors.Error}
+
+Indicates that an attempt is being made to access a variable that is not
+defined. Such errors commonly indicate typos in code, or an otherwise broken
+program.
+
+While client code may generate and propagate these errors, in practice, only V8
+will do so.
+
+```js
+doesNotExist;
+// Throws ReferenceError, doesNotExist is not a variable in this program.
+```
+
+Unless an application is dynamically generating and running code,
+`ReferenceError` instances indicate a bug in the code or its dependencies.
+
+## Class: `SyntaxError`
+
+* Extends: {errors.Error}
+
+Indicates that a program is not valid JavaScript. These errors may only be
+generated and propagated as a result of code evaluation. Code evaluation may
+happen as a result of `eval`, `Function`, `require`, or [vm][]. These errors
+are almost always indicative of a broken program.
+
+```js
+try {
+ require('vm').runInThisContext('binary ! isNotOk');
+} catch (err) {
+ // 'err' will be a SyntaxError.
+}
+```
+
+`SyntaxError` instances are unrecoverable in the context that created them –
+they may only be caught by other contexts.
+
+## Class: `SystemError`
+
+* Extends: {errors.Error}
+
+Node.js generates system errors when exceptions occur within its runtime
+environment. These usually occur when an application violates an operating
+system constraint. For example, a system error will occur if an application
+attempts to read a file that does not exist.
+
+* `address` {string} If present, the address to which a network connection
+ failed
+* `code` {string} The string error code
+* `dest` {string} If present, the file path destination when reporting a file
+ system error
+* `errno` {number} The system-provided error number
+* `info` {Object} If present, extra details about the error condition
+* `message` {string} A system-provided human-readable description of the error
+* `path` {string} If present, the file path when reporting a file system error
+* `port` {number} If present, the network connection port that is not available
+* `syscall` {string} The name of the system call that triggered the error
+
+### `error.address`
+
+* {string}
+
+If present, `error.address` is a string describing the address to which a
+network connection failed.
+
+### `error.code`
+
+* {string}
+
+The `error.code` property is a string representing the error code.
+
+### `error.dest`
+
+* {string}
+
+If present, `error.dest` is the file path destination when reporting a file
+system error.
+
+### `error.errno`
+
+* {number}
+
+The `error.errno` property is a negative number which corresponds
+to the error code defined in [`libuv Error handling`][].
+
+On Windows the error number provided by the system will be normalized by libuv.
+
+To get the string representation of the error code, use
+[`util.getSystemErrorName(error.errno)`][].
+
+### `error.info`
+
+* {Object}
+
+If present, `error.info` is an object with details about the error condition.
+
+### `error.message`
+
+* {string}
+
+`error.message` is a system-provided human-readable description of the error.
+
+### `error.path`
+
+* {string}
+
+If present, `error.path` is a string containing a relevant invalid pathname.
+
+### `error.port`
+
+* {number}
+
+If present, `error.port` is the network connection port that is not available.
+
+### `error.syscall`
+
+* {string}
+
+The `error.syscall` property is a string describing the [syscall][] that failed.
+
+### Common system errors
+
+This is a list of system errors commonly-encountered when writing a Node.js
+program. For a comprehensive list, see the [`errno`(3) man page][].
+
+* `EACCES` (Permission denied): An attempt was made to access a file in a way
+ forbidden by its file access permissions.
+
+* `EADDRINUSE` (Address already in use): An attempt to bind a server
+ ([`net`][], [`http`][], or [`https`][]) to a local address failed due to
+ another server on the local system already occupying that address.
+
+* `ECONNREFUSED` (Connection refused): No connection could be made because the
+ target machine actively refused it. This usually results from trying to
+ connect to a service that is inactive on the foreign host.
+
+* `ECONNRESET` (Connection reset by peer): A connection was forcibly closed by
+ a peer. This normally results from a loss of the connection on the remote
+ socket due to a timeout or reboot. Commonly encountered via the [`http`][]
+ and [`net`][] modules.
+
+* `EEXIST` (File exists): An existing file was the target of an operation that
+ required that the target not exist.
+
+* `EISDIR` (Is a directory): An operation expected a file, but the given
+ pathname was a directory.
+
+* `EMFILE` (Too many open files in system): Maximum number of
+ [file descriptors][] allowable on the system has been reached, and
+ requests for another descriptor cannot be fulfilled until at least one
+ has been closed. This is encountered when opening many files at once in
+ parallel, especially on systems (in particular, macOS) where there is a low
+ file descriptor limit for processes. To remedy a low limit, run
+ `ulimit -n 2048` in the same shell that will run the Node.js process.
+
+* `ENOENT` (No such file or directory): Commonly raised by [`fs`][] operations
+ to indicate that a component of the specified pathname does not exist. No
+ entity (file or directory) could be found by the given path.
+
+* `ENOTDIR` (Not a directory): A component of the given pathname existed, but
+ was not a directory as expected. Commonly raised by [`fs.readdir`][].
+
+* `ENOTEMPTY` (Directory not empty): A directory with entries was the target
+ of an operation that requires an empty directory, usually [`fs.unlink`][].
+
+* `ENOTFOUND` (DNS lookup failed): Indicates a DNS failure of either
+ `EAI_NODATA` or `EAI_NONAME`. This is not a standard POSIX error.
+
+* `EPERM` (Operation not permitted): An attempt was made to perform an
+ operation that requires elevated privileges.
+
+* `EPIPE` (Broken pipe): A write on a pipe, socket, or FIFO for which there is
+ no process to read the data. Commonly encountered at the [`net`][] and
+ [`http`][] layers, indicative that the remote side of the stream being
+ written to has been closed.
+
+* `ETIMEDOUT` (Operation timed out): A connect or send request failed because
+ the connected party did not properly respond after a period of time. Usually
+ encountered by [`http`][] or [`net`][]. Often a sign that a `socket.end()`
+ was not properly called.
+
+## Class: `TypeError`
+
+* Extends {errors.Error}
+
+Indicates that a provided argument is not an allowable type. For example,
+passing a function to a parameter which expects a string would be a `TypeError`.
+
+```js
+require('url').parse(() => { });
+// Throws TypeError, since it expected a string.
+```
+
+Node.js will generate and throw `TypeError` instances *immediately* as a form
+of argument validation.
+
+## Exceptions vs. errors
+
+<!--type=misc-->
+
+A JavaScript exception is a value that is thrown as a result of an invalid
+operation or as the target of a `throw` statement. While it is not required
+that these values are instances of `Error` or classes which inherit from
+`Error`, all exceptions thrown by Node.js or the JavaScript runtime *will* be
+instances of `Error`.
+
+Some exceptions are *unrecoverable* at the JavaScript layer. Such exceptions
+will *always* cause the Node.js process to crash. Examples include `assert()`
+checks or `abort()` calls in the C++ layer.
+
+## OpenSSL errors
+
+Errors originating in `crypto` or `tls` are of class `Error`, and in addition to
+the standard `.code` and `.message` properties, may have some additional
+OpenSSL-specific properties.
+
+### `error.opensslErrorStack`
+
+An array of errors that can give context to where in the OpenSSL library an
+error originates from.
+
+### `error.function`
+
+The OpenSSL function the error originates in.
+
+### `error.library`
+
+The OpenSSL library the error originates in.
+
+### `error.reason`
+
+A human-readable string describing the reason for the error.

+
+<a id="ERR_AMBIGUOUS_ARGUMENT"></a>
+### `ERR_AMBIGUOUS_ARGUMENT`
+
+A function argument is being used in a way that suggests that the function
+signature may be misunderstood. This is thrown by the `assert` module when the
+`message` parameter in `assert.throws(block, message)` matches the error message
+thrown by `block` because that usage suggests that the user believes `message`
+is the expected message rather than the message the `AssertionError` will
+display if `block` does not throw.
+
+<a id="ERR_ARG_NOT_ITERABLE"></a>
+### `ERR_ARG_NOT_ITERABLE`
+
+An iterable argument (i.e. a value that works with `for...of` loops) was
+required, but not provided to a Node.js API.
+
+<a id="ERR_ASSERTION"></a>
+### `ERR_ASSERTION`

+### `ERR_BUFFER_CONTEXT_NOT_AVAILABLE`
+
+An attempt was made to create a Node.js `Buffer` instance from addon or embedder
+code, while in a JS engine Context that is not associated with a Node.js
+instance. The data passed to the `Buffer` method will have been released
+by the time the method returns.
+
+When encountering this error, a possible alternative to creating a `Buffer`
+instance is to create a normal `Uint8Array`, which only differs in the

+HTTP parsing will abort without a request or response object being created, and
+an `Error` with this code will be emitted.
+
+<a id="HPE_UNEXPECTED_CONTENT_LENGTH"></a>
+### `HPE_UNEXPECTED_CONTENT_LENGTH`
+
+Server is sending both a `Content-Length` header and `Transfer-Encoding: chunked`.
+
+`Transfer-Encoding: chunked` allows the server to maintain an HTTP persistent
+connection for dynamically generated content.
+In this case, the `Content-Length` HTTP header cannot be used.
+
+Use `Content-Length` or `Transfer-Encoding: chunked`.

+### `MODULE_NOT_FOUND`
+<!-- YAML
+changes:
+ - version: v12.0.0
+ pr-url: https://github.com/nodejs/node/pull/25690
+ description: Added `requireStack` property.

+### `ERR_UNKNOWN_STDIN_TYPE`
+<!-- YAML
+added: v8.0.0
+removed: v11.7.0
+-->
+
+An attempt was made to launch a Node.js process with an unknown `stdin` file
+type. This error is usually an indication of a bug within Node.js itself,
+although it is possible for user code to trigger it.
