86 * Well, not quite. Using certain escape sequences, an
87 * application (or better yet, curses) can redefine the colors (at
88 * least some of them) and then those are used. Read the
89 * curs_color manpage, and the part about "ccc" and "initc" in the
90 * terminfo manpage. This is what the part of main-gcu inside the
91 * "if (can_fix_color)" code does.

98 * Well, it is possible, though you have to patch main-gcu
99 * and edit a terminfo entry. Apparently the relevant code in
100 * main-gcu was never tested (it's broken in at least one major
101 * way). Apply the patch at the end of this message (notice that
102 * we need to define REDEFINE_COLORS at some point near the
103 * beginning of the file).
104 * Next, write this termcap entry to a file:
106 * linux-c|linux console 1.3.6+ with private palette for each virtual console,
108 * colors#16, pairs#64,
109 * initc=\E]P%x%p1%{16}%/%02x%p1%{16}%/%02x%p1%{16}%/%02x,
113 * and run "tic" on it to produce a new terminfo entry called
114 * "linux-c". Especially note the "ccc" flag which says that we
115 * can redefine colors. The ugly "initc" string is what tells
116 * the console how to redefine a color. Now, just set your TERM
117 * variable to "linux-c" and try Angband again. If I've
118 * remembered to tell you everything that I've done, you should
119 * get the weird light-blue slate changed to a gray.
120 * Now, there are still lots of problems with this.
121 * Something (I don't think it's curses, either the kernel or
122 * the hardware itself) seems to be ignoring my color changes to
123 * colors 6 and 7, which is annoying. Also, the normal "white"
124 * color is now way too bright, but it's now necessary to
125 * distinguish it from the other grays.
126 * The kernel seems to support 16 colors, but you can
127 * only switch to 8 of those, due to VT102 compatibility, it
128 * seems. I think it would be possible to patch the kernel and
129 * allow all 16 colors to be used, but I haven't built up the
130 * nerve to try that yet.
131 * Let me know if you can improve on this any. Some of
132 * this may actually work differently on other hardware (ugh).
139 * To use this file, you must define "USE_GCU" in the Makefile.
141 * Hack -- note that "angband.h" is included AFTER the #ifdef test.
142 * This was necessary because of annoying "curses.h" silliness.
144 * Note that this file is not "intended" to support non-Unix machines,
145 * nor is it intended to support VMS or other bizarre setups.
147 * Also, this package assumes that the underlying "curses" handles both
148 * the "nonl()" and "cbreak()" commands correctly, see the "OPTION" below.
150 * This code should work with most versions of "curses" or "ncurses",
151 * and the "main-ncu.c" file (and USE_NCU define) are no longer used.
153 * See also "USE_CAP" and "main-cap.c" for code that bypasses "curses"
154 * and uses the "termcap" information directly, or even bypasses the
155 * "termcap" information and sends direct vt100 escape sequences.
157 * XXX XXX XXX Consider the use of "savetty()" and "resetty()".
