Add output_prefix_length to diff_options

2012-04-16T18:28:30Z

Add output_prefix_length to diff_options. Initialize the value to 0 and only set it when graph.c:diff_output_prefix_callback() is called. Signed-off-by: Lucian Poston Signed-off-by: Junio C Hamano

color: delay auto-color decision until point of use

2011-08-19T22:51:34Z

When we read a color value either from a config file or from the command line, we use git_config_colorbool to convert it from the tristate always/never/auto into a single yes/no boolean value. This has some timing implications with respect to starting a pager. If we start (or decide not to start) the pager before checking the colorbool, everything is fine. Either isatty(1) will give us the right information, or we will properly check for pager_in_use(). However, if we decide to start a pager after we have checked the colorbool, things are not so simple. If stdout is a tty, then we will have already decided to use color. However, the user may also have configured color.pager not to use color with the pager. In this case, we need to actually turn off color. Unfortunately, the pager code has no idea which color variables were turned on (and there are many of them throughout the code, and they may even have been manipulated after the colorbool selection by something like "--color" on the command line). This bug can be seen any time a pager is started after config and command line options are checked. This has affected "git diff" since 89d07f7 (diff: don't run pager if user asked for a diff style exit code, 2007-08-12). It has also affect the log family since 1fda91b (Fix 'git log' early pager startup error case, 2010-08-24). This patch splits the notion of parsing a colorbool and actually checking the configuration. The "use_color" variables now have an additional possible value, GIT_COLOR_AUTO. Users of the variable should use the new "want_color()" wrapper, which will lazily determine and cache the auto-color decision. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

diff: refactor COLOR_DIFF from a flag into an int

2011-08-18T21:35:53Z

This lets us store more than just a bit flag for whether we want color; we can also store whether we want automatic colors. This can be useful for making the automatic-color decision closer to the point of use. This mostly just involves replacing DIFF_OPT_* calls with manipulations of the flag. The biggest exception is that calls to DIFF_OPT_TST must check for "o->use_color > 0", which lets an "unknown" value (i.e., the default) stay at "no color". In the previous code, a value of "-1" was not propagated at all. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

Share color list between graph and show-branch

2011-04-05T06:20:39Z

This also adds the new colors to show-branch that were added a while back for graph output. Signed-off-by: Dan McGee Signed-off-by: Junio C Hamano

rev-list/log: factor out revision mark generation

2011-03-09T21:50:54Z

Currently, we have identical code for generating revision marks ('<', '>', '-') in 5 places. Factor out the code to a single function get_revision_mark() for easier maintenance and extensibility. Note that the check for !!revs in graph.c (which gets removed effectively by this patch) is superfluous. Signed-off-by: Michael J Gruber Signed-off-by: Junio C Hamano

Enable custom schemes for column colors in the graph API

2010-07-13T23:33:02Z

Currently, the graph code is hardcoded to use ANSI color escapes for coloring the column characters in the generated graphs. This patch allows a custom scheme of colors to be set at runtime, allowing different types of color escapes to be used. A new function - graph_set_column_colors() - is added to the graph.h API, which allows a custom column_colors array (and column_colors_max value) to replace the builtin ANSI array (and _max value). The new function - if used - must be called before graph_init() is called. Signed-off-by: Johan Herland Signed-off-by: Junio C Hamano

Make graph_next_line() available in the graph.h API

2010-07-13T23:32:30Z

In order to successfully use the graph API from a context other than the stdout/command-line scenario (where the graph_show_* functions are suitable), we need direct access to graph_next_line(), to drive the graph drawing process. Signed-off-by: Johan Herland Signed-off-by: Junio C Hamano
