Move color option parsing out of diff.c and into color.[ch] The intent is to lib-ify colorizing code so it can be reused. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <junkio@cox.net>

Add a notice that only certain functions can print color escape codes We emulate color escape codes on Windows by overriding printf, fprintf, and fputs. Warn developers that these are the only functions that can be used to print them. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Provide git_config with a callback-data parameter git_config() only had a function parameter, but no callback data parameter. This assumes that all callback functions only modify global variables. With this patch, every callback gets a void * parameter, and it is hoped that this will help the libification effort.

git config --get-colorbool This adds an option to help scripts find out color settings from the configuration file. git config --get-colorbool color.diff inspects color.diff variable, and exits with status 0 (i.e. success) if color is to be used. It exits with status 1 otherwise. If a script wants "true"/"false" answer to the standard output of the command, it can pass an additional boolean parameter to its command line, telling if its standard output is a terminal, like this: git config --get-colorbool color.diff true When called like this, the command outputs "true" to its standard output if color is to be used (i.e. "color.diff" says "always", "auto", or "true"), and "false" otherwise.

int git_config_colorbool(const char *var, const char *value, int stdout_is_tty);
color: make it easier for non-config to parse color specs We have very featureful color-parsing routines which are used for color.diff.* and other options. Let's make it easier to use those routines from other parts of the code. This patch adds a color_parse_mem() helper function which takes a length-bounded string instead of a NUL-terminated one. While the helper is only a few lines long, it is nice to abstract this out so that: - callers don't forget to free() the temporary buffer - right now, it is implemented in terms of color_parse(). But it would be more efficient to reverse this and implement color_parse in terms of color_parse_mem. This also changes the error string for an invalid color not to mention the word "config", since it is not always appropriate (and when it is, the context is obvious since the offending config variable is given). Finally, while we are in the area, we clean up the parameter names in the declaration of color_parse; the var and value parameters were reversed from the actual implementation.
