* graph.c: mark private file-scope symbols as staticJunio C Hamano2012-09-151-27/+0

* Enable custom schemes for column colors in the graph APIJohan Herland2010-07-131-0/+17
| | | | | | | | | | | | | | | 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 <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* Make graph_next_line() available in the graph.h APIJohan Herland2010-07-131-0/+11
| | | | | | | | | | 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.

* graph.c: make many functions staticNanako Shiraishi2008-09-251-40/+0
| | | | | | | | These function are not used anywhere. Also removes graph_release() that is never called. Signed-off-by: Nanako Shiraishi <nanako3@lavabit.com> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
* log --graph --left-right: show left/right information in place of '*'Adam Simpkins2008-05-251-1/+1
| | | | | | | | | | | | | | | | | With the --graph option, the graph already outputs 'o' instead of '*' for boundary commits. Make it emit '<' or '>' when --left-right is specified. (This change also disables the '^' prefix for UNINTERESTING commits. The graph code currently doesn't print anything special for these commits, since it assumes no UNINTERESTING, non-BOUNDARY commits are displayed. This is potentially a bug if UNINTERESTING non-BOUNDARY commits can actually be displayed via some code path.) [jc: squashed the left-right change from Dscho and Adam's fixup into one] Signed-off-by: Adam Simpkins <adam@adamsimpkins.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
