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

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.

  Make graph_next_line() available in the graph.h API
  Enable custom schemes for column colors in the graph API
