4 /* what are moodules in elementary for? for modularising behavior and features
5 * so they can be plugged in and out where you dont want the core source to
6 * always behave like that or do it that way. plug it at runtime!
8 * they have module names (in config) and "slots" to plug that module into
9 * to server a purpose. eg you plug plugin "xx" into the "entry-copy-paste"
10 * slot so it would provide replacement copy & paste ui functionality and
13 * config is something like:
15 * export ELM_MODULES="xx>slot1:yy>slot2"
17 * where a module named xx is plugged into slot1 & yy is plugged into slot2
21 * export ELM_MODULES="my_module>entry/api"
23 * this loads the module called "my_module" into the slot "entry/api" which
24 * is an api slot for entry modules to modify behavior and hook to
25 * creation/deletion of the entry as well as replace the longpress behavior.
