git-graph's Issues

boring commits have commit endpoints in reverse order

Thanks for fixing the other issue where the script wouldn't work if builder 3.0.0 was used. The script is in a usable state now.

I noticed another issue where the boring commits have the commit SHA1s in reverse order. I'd expect the older SHA1 on the left and the newer SHA1 on the right. I think the problem is on line 238 of the script. Do you see this as an issue?

PS: not everyone writes good commit messages. So there can be big commit messages (spanning multiple lines), which would make big ellipses in the output. If you can only the first 50 characters as the commit message, the output graph would look better.

"doesn't know its parents" error message — need to use gitlab-grit

This tools doesn't work in default installation (at least on Cygwin). It just produces
#omitting #xxx that doesn't know its parents
for every item.

The command gem install gitlab-grit solves this problem. It installs GitLab fork of Grit version 2.8.1 (for the moment).

Whereas by default Grit 2.5.0 is installed. But it seems that this version is outdated now and Grit is no longer maintained.

In default installation, ref.parents throws NoMethodError on every item in filtering decorated list:

decorated.reject!{|ref|
begin
  ref.parents
  false
rescue NoMethodError
  puts "#omitting #{ref} that doesn't know its parents"
  true
end}

Actually, repo.branches[0].commit.parents throws error:

NoMethodError: undefined method `>>' for "x":String

Help me to fix this error: undefined method `encode' for Builder, please

$ ruby --version

and, I installed grit-2.5.0 , builder-3.0.0

I can't run git-graph.rb

$ ruby -I/var/lib/gems/1.8/gems/grit-2.5.0/lib git-graph.rb . | dot -Tsvg -ohistory.svg /dev/stdin

The sample command doesn't work. I have the 'grit' gem installed.

When executing on this git repository: https://android.googlesource.com/kernel/goldfish.git

$ ./git-graph.rb /local/scratch/drt24/android/clones/kernel/goldfish

I get lots of lines like:

Bug with escaping quotes for svg & another image format

Hi,
First of all, I am using your script and i love it.
But there's a bug i found i think you might want to fix, it's simple:)

you use fast_xs to escape the double qoutes, just for generate a VALID XML file, for the SVG, right?

but, when someone, like me, wants a PNG file, this script will make &amp, &quot shows in the text of the picture. which is not right.

e.g: i have a commit:

commit b5941e3ba596bae219299ca480c8c48683b5b644
Author: sunus <[email protected]>
Date:   Tue Dec 10 21:19:38 2013 +0800

    Revert "remove FILE"

    This reverts commit 163a6d700226b780b7852a79fe1370a6d38c819a.

it shows Revert $quot; remove FILE $quot; (replace $ with &)

and i think it shouldn't

as far as i tested, you all just use this:

wrap_text(commit_msg + " [" + id_for(commit) + "]").gsub(%r|\n|, "
")

both PNG and SVG works fine.

that's what i got with your script.
