Windows support

[wernight]

Most issues are on grit side but basically to make it work on Windows in a msysgit I had to:

• Install git-up (like described)
• Patch lib/grit/git.rb (see wernight/grit@bdc23bd)
• Patch lib/posix/spawn.rb (see stereobooster/posix-spawn@67a73c6)
• Use ansicon to get colors: $ ansicon git up

Possibly using https://github.com/schacon/grit would works without most of those patches.Using another coloring system in place of the current one would be advisable as it is deprecated.

Do you have a local version of git-up with the changes you describe? Care to fork/pull-request if so, so I can have a look?

[wernight]

Yes on my profile page. I'm using it daily exactly with ansicon.

Specifically, applying both of these:

wernight/grit@bdc23bd
stereobooster/posix-spawn@67a73c6

To grit and posix (respectively) fixes the issue. I have it working, though I haven't really bothered with the coloring issue. Black and white is just fine for now.

[wernight]

Yes correct, I forgot about the second one.

Coloring wouldn't such an issue if it didn't display the ANSI code. HA HA

[youcandanch]

True, and ansicon is pretty great anyway. Not too hard to throw it in path and alias over it. Figured that out about 5 minutes after my post ;]

If, like me, you're an idiot and let the msysGit install put it in the default directory (C:\Program Files (x86)), you're going to get some errors when trying to rebase (command line doesn't escape the parens or spaces properly). Uninstalling / reinstalling in a proper directory structure fixes that.

@alexdancho @wernight Would one of you care to fork git-up and write a WINDOWS.md describing how to get it running under Windows?

[wernight]

I've updated the summary to describe all the steps. That should be similar. As the commands are pretty advanced I'd advise against doing it manually in an official read-me.
