13 * This file has 2 sections:
15 * Settings always true for OS-9 systems.
18 /* User preferences. */
21 * SECURE is 1 if you wish to disable a bunch of features in order to
22 * be safe to run by unprivileged users.
27 * SHELL_ESCAPE is 1 if you wish to allow shell escapes.
28 * (This is possible only if your system supplies the system() function.)
30 #define SHELL_ESCAPE (!SECURE)
33 * EXAMINE is 1 if you wish to allow examining files by name from within less.
35 #define EXAMINE (!SECURE)
38 * TAB_COMPLETE_FILENAME is 1 if you wish to allow the TAB key
39 * to complete filenames at prompts.
41 #define TAB_COMPLETE_FILENAME 1
44 * CMD_HISTORY is 1 if you wish to allow keys to cycle through
45 * previous commands at prompts.
50 * HILITE_SEARCH is 1 if you wish to have search targets to be
51 * displayed in standout mode.
53 #define HILITE_SEARCH 1
56 * EDITOR is 1 if you wish to allow editor invocation (the "v" command).
57 * (This is possible only if your system supplies the system() function.)
58 * EDIT_PGM is the name of the (default) editor to be invoked.
60 #define EDITOR (!SECURE)
61 #define EDIT_PGM "umacs"
64 * TAGS is 1 if you wish to support tag files.
66 #define TAGS (!SECURE)
69 * USERFILE is 1 if you wish to allow a .less file to specify
70 * user-defined key bindings.
72 #define USERFILE (!SECURE)
75 * GLOB is 1 if you wish to have shell metacharacters expanded in filenames.
76 * This will generally work if your system provides the "popen" function
77 * and the "echo" shell command.
79 #define GLOB (!SECURE)
82 * PIPEC is 1 if you wish to have the "|" command
83 * which allows the user to pipe data into a shell command.
85 #define PIPEC (!SECURE)
88 * LOGFILE is 1 if you wish to allow the -l option (to create log files).
90 #define LOGFILE (!SECURE)
93 * GNU_OPTIONS is 1 if you wish to support the GNU-style command
94 * line options --help and --version.
99 * ONLY_RETURN is 1 if you want RETURN to be the only input which
100 * will continue past an error message.
101 * Otherwise, any key will continue past an error message.
103 #define ONLY_RETURN 0
106 * LESSKEYFILE is the filename of the default lesskey output file
107 * (in the HOME directory).
108 * LESSKEYFILE_SYS is the filename of the system-wide lesskey output file.
109 * DEF_LESSKEYINFILE is the filename of the default lesskey input
110 * (in the HOME directory).
111 * LESSHISTFILE is the filename of the history file
112 * (in the HOME directory).
