code-review
code-review is a tool for reviewing diffs in a git or mercurial repository.
It provides a simple CLI for stepping through the modified files, and viewing
the differences with an external diff tool. This is very convenient if you
prefer using an interactive side-by-side diff viewer. Although you could also
use the GIT_EXTERNAL_DIFF environment variable with git diff,
code-review provides much more flexibility for moving between files and
selecting which versions to diff.
Installation
From the root of the source tree, run:
$ python setup.py install
Also see the INSTALL file.
Setup
codet-review uses vimdiff by default. You may set the CODE_REVIEW_DIFF
environment variable to point to your favourite diff program.
Usage
Enter code-review -? to see the help message. Here are some examples:
To diff commit_a (descendent) against commit_b (ancestor):
$ code-review <commit_b> <commit_a>
To diff the working tree against commit_a:
$ code-review <commit_a>
To diff the index against commit_a:
$ code-review --cached <commit_a>
To diff a particular commit against its immediate parent:
$ code-review -c <commit>
Once code-review is running, you should see a prompt menu. By default, it goes
through all the changed files and show the diff one by one. You can enter
? to see all available commands. The prompt also accepts unambiguous
command prefixes. Here is an example of a review session:
[dsom:code-review]$ code-review HEAD^ Now processing modified file README.rst README.rst [diff]> l 0: M README.rst 1: M setup.py 2: M src/code-review README.rst [diff]> go 2 Now processing modified file src/code-review code-review [diff]> d code-review [quit]>
