Pull request review (prr)

Last month I developed a new tool that brings mailing-list style code
reviews to github. The tool was born out of frustration with github's
point and click web UI. Since I do a lot of code review, the tabbing
between my text editor and my browser became a constant source of
friction.

Ideally, I wanted to stay in my text editor so that my code writing
and code reviewing workflows could be unified. I didn't find any such
tool on the internet so I built my own.

Demo

Consider the following pull request:

[pr]

To download the PR for review:

$ prr get danobi/prr-test-repo/2
/home/dxu/dev/review/danobi/prr-test-repo/2.prr

When you open the review file, you'll see:

 > diff --git a/ch4.txt b/ch4.txt
 > index 41e1932..8741175 100644
 > --- a/ch4.txt
 > +++ b/ch4.txt

Now suppose you want to have the author remove the extraneous edits
and reject the PR because of it. Simply mark up the review file as
follows:

 @prr reject
 
 > diff --git a/ch4.txt b/ch4.txt
 > index 41e1932..8741175 100644

 Remove this junk
 
 >  9. Neither is it the acme of excellence if you fight and conquer and the whole Empire says, "Well done!"
 >

Two things to note:

 1. We can use prr directives by "tagging" @prr. Just like how you
    might use a github bot.
 2. We added a "spanned" comment on the hunk by adding a newline
    before the start of the span.

To submit the review back to github, run:

$ prr submit danobi/prr-test-repo/2

You'll now see something like this on github:

[comment]

(Note that you don't see the "Changes requested" in this example
because github doesn't let you request changes on your own PR. It
should work on a real PR.)

Looking forward

The above demo shows off most of the features I've currently
implemented. There's still a few things I want to add but they're not
too pressing as I'm currently using prr every day just fine.

If you wanna try out prr or request new features, feel free to file
an issue or open a PR at https://github.com/danobi/prr .
