2008-05-25graph API: don't print branch lines for uninteresting merge parentsAdam Simpkins1-13/+44
Previously, the graphing code printed lines coming out of a merge commit for all of its parents, even if some of them were uninteresting. Now it only prints lines for interesting commits. For example, for a merge commit where only the first parent is interesting, the code now prints: * merge commit * interesting child instead of: M merge commit |\ * interesting child Signed-off-by: Adam Simpkins <adam@adamsimpkins.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-05-25graph API: fix graph mis-alignment after uninteresting commitsAdam Simpkins1-0/+3
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 * | Signed-off-by: Adam Simpkins <adam@adamsimpkins.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-05-05graph API: eliminate unnecessary indentationAdam Simpkins1-14/+52
This change improves the calculation of the amount of horizontal padding, so that there is always exactly 1 space of padding. Previously, most commits had 3 spaces of padding, but commits that didn't have any children in the graph had only 1 space of padding.
