[PATCH 0/2] Preparing the graph API for external users

[Johan Herland <johan@herland.net>]

Hi,

I'm playing around with some CGit patches for enabling an ASCII-art
commit graph to be displayed on CGit's 'log' page. These patches reuse
the ASCII-art commit graph that is produced by 'git log --graph'.

However, in order to allow proper reuse by CGit, I need to make a
couple of changes to the graph API:

The first patch exposes graph_next_line() in the graph.h API. This
function is needed to drive the graph generation from CGit. (Since
the graph_show_* functions print directly to stdout, they can not be
used by CGit.)

The second patch allows CGit to use a different coloring mechanism
than the default ANSI color escapes in graph.c. CGit replaces the
column_colors array of ANSI escapes in graph.c with its own array that
contains HTML <span> tags (which are then styled to the appropriate
colors using CSS).

For reference, the corresponding CGit patches that generate the commit
graph on CGit's log page will follow as a separate patch series.
