Michael J Gruber 1df2d656cc rev-list/log: factor out revision mark generation
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.

Johan Herland 1e3d4119d2 Enable custom schemes for column colors in the graph API
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.

In order to successfully use the graph API from a context other than the
stdout/command-line scenario (where the graph_show_* functions are

Add GIT_COLOR_BOLD_* macros to set both bold and the color in one
sequence.  This saves two characters of output ("ESC [ m", minus ";")
and makes the code more readable.

Add the remaining GIT_COLOR_BG_* macros to make the list complete.

Adam Simpkins beb5af43a6 graph API: fix bug in graph_is_interesting()
Previously, graph_is_interesting() did not behave quite the same way as
the code in get_revision().  As a result, it would sometimes think
commits were uninteresting, even though get_revision() would return
them.  This resulted in incorrect lines in the graph output.

This change creates a get_commit_action() function, which
graph_is_interesting() and simplify_commit() both now use to determine
if a commit will be shown.  It is identical to the old simplify_commit()
behavior, except that it never calls rewrite_parents().

This problem was reported by Santi Béjar.  The following command
would exhibit the problem before, but now works correctly:

  git log --graph --simplify-by-decoration --oneline v1.6.3.3

Previously git graph did not display the output for this command
correctly between f29ac4f and 66996ec, among other places.

Many call sites use strbuf_init(&foo, 0) to initialize local
strbuf variable "foo" which has not been accessed since its
declaration. These can be replaced with a static initialization
using the STRBUF_INIT macro which is just as readable, saves a
function call, and takes up fewer lines.

Adam Simpkins a0ebe573a5 graph API: fix "git log --graph --first-parent"
This change teaches the graph API that only the first parent of each
commit is interesting when "--first-parent" was specified.

This change also consolidates the graph parent walking logic into two
new internal functions, first_interesting_parent() and
next_interesting_parent().  A simpler fix would have been to simply
break at the end of the 2 existing for loops when
graph->revs->first_parent_only is set.  However, this change seems
nicer, especially if we ever need to add any new loops over the parent
list in the future.

Adam Simpkins f1979d6b3f graph API: avoid printing unnecessary padding before some octopus merges
When an octopus merge is printed, several lines are printed before it to
move over existing branch lines to its right.  This is needed to make
room for the children of the octopus merge.  For example:

| | | |
| |  \ \
| |   \ \
| |    \ \
| M---. \ \
| |\ \ \ \ \

However, this step isn't necessary if there are no branch lines to the
right of the octopus merge.  Therefore, skip this step when it is not
needed, to avoid printing extra lines that don't really serve any
purpose.

Adam Simpkins 3395908ee4 graph API: improve display of merge commits
This change improves the way merge commits are displayed, to eliminate a
few visual artifacts.  Previously, merge commits were displayed as:

| M  \
| |\  |

As pointed out by Teemu Likonen, this didn't look nice if the rightmost
branch line was displayed as '\' on the previous line, as it then
appeared to have an extra space in it:

| |\
| M  \
| |\  |

This change updates the code so that branch lines to the right of merge
commits are printed slightly differently depending on how the previous
line was displayed:

| |\          | | |        | |  /
| M \         | M |        | M |
| |\ \        | |\ \       | |\ \

Adam Simpkins 3c68d67b57 Fix output of "git log --graph --boundary"
Previously the graphing API wasn't aware of the revs->boundary flag, and
it always assumed that commits marked UNINTERESTING would not be
displayed.  As a result, the boundary commits were printed at the end of
the log output, but they didn't have any branch lines connecting them to
their children in the graph.

There was also another bug in the get_revision() code that caused
graph_update() to be called twice on the first boundary commit.  This
caused the graph API to think that a commit had been skipped, and print
a "..." line in the output.

With the --graph option, the graph already outputs 'o' instead of '*'
for boundary commits.  Make it emit '<' or '>' when --left-right is

(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.)

Adam Simpkins 2ecbd0a0db graph API: fix graph mis-alignment after uninteresting commits
The graphing code had a bug that caused it to output branch lines
incorrectly after ignoring an uninteresting commit.  When computing how
to match up the branch lines from the current commit to the next one, it
forgot to take into account that it needed to initially start with 2
empty spaces where the missing commit would have gone.

So, instead of drawing this,

  | * | <- Commit with uninteresting parent
  |  /
  * |

It used to incorrectly draw this:

  | * | <- Commit with uninteresting parent
  * |
