Introduction

Where to get it

CvsGraph in action

• ViewVC with CvsGraph - CvsGraph is officially supported by ViewVC (previously known as ViewCVS) as of version 0.8.
• CvsWeb with CvsGraph - For more info about FreeBSD-CVSweb, see http://www.freebsd.org/projects/cvsweb.html

An example

./cvsgraph -O'merge_from="^source_(.*)"; merge_to="^merge_%1$"; merge_color="#e00000"' \
	-O'merge_from="^source2_(.*)"; merge_to="^merge2_%1$"; merge_color="#00e000"' \
	-O'strip_untagged=1; strip_first_rev=0; transparent_bg=1' \
	-o ../t.png -r. -m. ../t.c,v

FAQ

Bugs

• Images can still be very large when you have many revisions and branches. You can reduce imagesize by using any combination of these options:

  strip_untagged	Reduce the number of revisions shown that have no tags
  strip_first_rev
  rev_maxtags	Reduce revision boxes by limiting the number of tags shown
  tag_ignore	Remove tags that match a regular expression
  rev_hidenumber	Do not display the revision number in revision boxes (and branch boxes)
  branch_fold	Fold all branches without revisions into one branch-box
  branch_foldall
  branch_subtree	Only show parts of the tree

Changes

Changes for 1.7.2

• Make config option rev_hidenumber function properly for branch boxes (see issue report)
• Also apply rev_hidenumber to folded branch boxes

Changes for 1.7.1

• Update cvsgraph after 11 years and relocate home after the original server went the way of dead Dodo bits (may its bytes zero in peace).
  • update autotools version
  • fix two printf format warning and unused var warning
  • use pkg-config for libgd and freetype
  • fix web and mail references
  • still being amazed of the portability and surviving 10+ years bitrot
  • bump the version to 1.7.1

Changes for 1.7.0

• Do a better job at drawing the merge lines by selecting the shortest path from the revision boxes. An analysis is now done whether the source and destinations should be on the left or right side.
• Fix the left_right case for merge lines to display correctly.
• Fix a +/-1 error on the merge lines to account for both rounding errors and the shadow of the revision boxes.
• Add configuration option 'merge_on_tag' to force the left_right case to display merge lines on the tags instead of on the top/bottom sides. This also solves imagemap overlaps where multiple sources or destinations would be displayed at the same position.
• Fix the imagemap function to record the correct position of the merges.
• Use automake
• Streamline the package with patches from the Fedora RPMS

Changes for 1.6.2

• Imagemap bugfix
• Never released

Changes for 1.6.1

• Minor textual fixes in the config manual page
• Do a better job at drawing merge lines. Ugly cross over lines could be generated if branches had the same parent. Now they are moved to the right (or bottom)

Pre 1.6.1 changes

• These are now moved to another page to make it more compact.

Links

• I just learned that there is another program that can make graphs of a cvs repository, called boneclipse-cvsgrapher which is at http://www.bonevich.com/boneclipse-master/boneclipse-cvsgrapher/index.html.
  It uses the Eclipse framework/IDE.
• WinCvs was the inspiration of the grapher.

Acknowledgements

• Many thanks to Jason Corley for the RPM spec-file
• Thanks to Russell Yanofsky and Chris Bridges (cvsgraph at rfel dot com) for the windows binaries.
  Please see http://www.cvsnt.org/wiki/CvsGraphMingw for details if you want to compile a windows binary. I do not know anything about it.
• Thanks to all others who contributed bugreports and patches which I probably have mentioned in a log or other places. Mail me if your ego is big enough to want a place on the frontpage ;-)
• * The icon used is shamelessly taken from the ViewCVS distro, file cvsgraph_16x16.png. I cannot find any reference to the original creator, otherwise I would gladly credit him or her personally.
