12 /* OS/9 definition file for less. */
14 * This file has 2 sections:
16 * Settings always true for OS-9 systems.
19 /* User preferences. */
22 * SECURE is 1 if you wish to disable a bunch of features in order to
23 * be safe to run by unprivileged users.
28 * SHELL_ESCAPE is 1 if you wish to allow shell escapes.
29 * (This is possible only if your system supplies the system() function.)
31 #define SHELL_ESCAPE (!SECURE)
34 * EXAMINE is 1 if you wish to allow examining files by name from within less.
36 #define EXAMINE (!SECURE)
39 * TAB_COMPLETE_FILENAME is 1 if you wish to allow the TAB key
40 * to complete filenames at prompts.
42 #define TAB_COMPLETE_FILENAME 1
45 * CMD_HISTORY is 1 if you wish to allow keys to cycle through
46 * previous commands at prompts.
51 * HILITE_SEARCH is 1 if you wish to have search targets to be
52 * displayed in standout mode.
54 #define HILITE_SEARCH 1
57 * EDITOR is 1 if you wish to allow editor invocation (the "v" command).
58 * (This is possible only if your system supplies the system() function.)
59 * EDIT_PGM is the name of the (default) editor to be invoked.
61 #define EDITOR (!SECURE)
62 #define EDIT_PGM "umacs"
65 * TAGS is 1 if you wish to support tag files.
67 #define TAGS (!SECURE)
70 * USERFILE is 1 if you wish to allow a .less file to specify
71 * user-defined key bindings.
73 #define USERFILE (!SECURE)
76 * GLOB is 1 if you wish to have shell metacharacters expanded in filenames.
77 * This will generally work if your system provides the "popen" function
78 * and the "echo" shell command.
80 #define GLOB (!SECURE)
83 * PIPEC is 1 if you wish to have the "|" command
84 * which allows the user to pipe data into a shell command.
86 #define PIPEC (!SECURE)
89 * LOGFILE is 1 if you wish to allow the -l option (to create log files).
91 #define LOGFILE (!SECURE)
94 * GNU_OPTIONS is 1 if you wish to support the GNU-style command
95 * line options --help and --version.
100 * ONLY_RETURN is 1 if you want RETURN to be the only input which
101 * will continue past an error message.
102 * Otherwise, any key will continue past an error message.
104 #define ONLY_RETURN 0
107 * LESSKEYFILE is the filename of the default lesskey output file
108 * (in the HOME directory).
109 * LESSKEYFILE_SYS is the filename of the system-wide lesskey output file.
110 * DEF_LESSKEYINFILE is the filename of the default lesskey input
111 * (in the HOME directory).
