Exclude pattern

[ozangunalp]

Implementation of the part 1 of exclude pattern option mentioned in #14.

The option can be given in command line via,
git octopus -e features/feat1 -e octopus-* -s 4
or defined in git config
git config octopus.excludePattern features/feat1
git config --add octopus.excludePattern octopus-*

The command line option overrides the git config.

Waow you wrote a test. It's been a while since I haven't run them. Does it still actually work?

[ozangunalp]

Well they still do work if you have access to docker base images. There is a failing test about saving conflict resolutions though. I left it as is.

I tried it on OSX, seems to work well.

I guess that you changed the doc files by hand ? what's in doc/ is actually generated based on files in src/doc/. Don't worry about updating generated files, I'll do it before the next release but put your changes in the sources.

my bad, thought I was editing src/doc. I'll transfer changes to the src file.
