Introduction
I code using the venerable Emacs editor and the extension Magit which is a powerfull text-based user interface to Git. Despite, I am happy with Magit for most tasks, I dislike the diff view rendering in Emacs.
Thus the goal of CodeReview is to provide a more convenient tool for code review tasks on local Git repositories. Unlike software like Gerrit, CodeReview is not designed to do team-level code review, but to check the stage before a commit and show the difference between two versions. In particular, CodeReview fills the gap with IDEs that don't provide a nice side-by-side diff view.
Historically, I wrote this tool as a replacement of qbzr for Git.
How to use CodeReview ?
CodeReview provides two applications pyqgit and diff-viewer.
Disclaimer
This tool was written 10 years ago (late 2011) and I am using it for my own needs, thus it works as is.
I tried to implement a file watching feature but it is a nightmare to debug.
The Qt code is now a bit out dated, but the actual diff viewer implementation would require some works to be ported to QML.
Features
The main features of CodeReview are:
- display and browse the log and paches of a Git repository
- diff side by side using Patience algorithm
- watch for file system changes
Diff viewer features:
- stage/unstage file
- number of context lines
- font size
- line number mode
- align mode
- complete mode
- highlight mode
Installation
CodeReview is written in Python and uses the GUI framework PyQt5 and the Git library pygit2. Thus, CodeReview is operating system agnostic and should work on Linux, Windows and OSX.
To install CodeReview from source code, you need a working Python environment and a C compiler.
On Linux
To summarise, you can easily install CodeReview on Linux with just pip install CodeReview but read the followings.
First you need to verify that Python is installed on your distribution.
If you install CodeReview from source, you will also need the GCC C compiler.
You can create a Python virtual environment to install CodeReview in its own container:
# create the venv
python3.10 -m venv $HOME/codereview
# enter in the venv
source $HOME/codereview/bin/activateThis is not mandatory, but it is a good practice if you don't know exactly what you are doing. Especially, if you don't want to spoil your distribution.
Notice, you can later create a shell script to wrap the venv activation and the pyqgit command.
Then install CodeReview either from PyPI (official Python package repository) or from source:
# source .tar.gz or wheel/binary from PyPI (can require a GCC C compiler)
pip install CodeReview
# from Git repository (require a GCC C compiler)
pip install git+https://github.com/FabriceSalvaire/CodeReviewIf the pip command is not available, you must install the corresponding package of your distribution.
Finally, run CodeReview to verify that the installation was successful:
pyqgit --help
diff-viewer --help
pyqgit git_repository_path
diff-viewer a.txt b.txt
cd git_repository_path
pyqgitExample of shell wrapper:
#! /usr/bin/bash
PY_ENV=${HOME}/codereview
source ${PY_ENV}/bin/activate
CodeReviewLogLevel='WARNING' ${PY_ENV}/bin/pyqgit $1 &You can also clone the repository and install it using theses commands:
git clone [email protected]:FabriceSalvaire/CodeReview.git
python setup.py build
python setup.py installOn Windows
Actually there is no installer available, but it is welcome.
You must follow the same procedure that for Linux. However it is a bit more difficult to achieve.
A suggestion is to install the Anaconda Python Distribution and got a working compiler.
On OSX
An up to date installation procedure is welcome.
Dependencies
CodeReview requires the dependencies listed in requirements.txt
How to help
- test it on Windows and OSX
- fix bugs: look at issues
- sometime pyqgit is slow: profile code to find issues
