43 Git Cola uses QtPy, so you can choose between PyQt6, PyQt5 and PySide2 by setting
44 the `QT_API` environment variable to `pyqt6`, `pyqt5` or `pyside2` as desired.
45 `qtpy` defaults to `pyqt6` and falls back to `pyqt6` and `pyside2` if `pyqt5`
48 Any of the following Python Qt libraries must be installed:
50 * [PyQt5 / PyQt6](https://www.riverbankcomputing.com/software/pyqt/download5)
51 5.6 or newer is required. Qt 6.0 is also supported via QtPy.
53 * [PySide2](https://github.com/PySide/PySide)
59 Git Cola enables additional features when the following
60 Python modules are installed.
62 [send2trash](https://github.com/hsoft/send2trash) enables cross-platform
63 "Send to Trash" functionality.

71 There are several ways to install Git Cola.
75 Linux is it! Your distro has probably already packaged `git-cola`.
76 If not, please file a bug against your distribution ;-)
80 Available in the [AUR](https://aur.archlinux.org/packages/git-cola/).
96 zypper install git-cola
100 Available in [SlackBuilds.org](http://slackbuilds.org/result/?search=git-cola).
104 [See here](https://packages.ubuntu.com/search?keywords=git-cola) for the
105 versions that are available in Ubuntu's repositories.
107 There was a [PPA by @pavreh](https://launchpad.net/~pavreh/+archive/ubuntu/git-cola)
108 but it has not been updated for a while.
113 # Install from official binary packages
114 pkg install -r FreeBSD devel/git-cola
117 cd /usr/ports/devel/git-cola && make clean install
120 ## Install into a Python Virtualenv from PyPI using pip
122 **IMPORTANT**: never run `pip install` or `make install` as root or outside of a
125 One way to install the latest released version is to use `venv` (virtualenv) and `pip`.
126 This installs [git-cola from pypi.org](https://pypi.org/project/git-cola/).
128 python3 -m venv --system-site-packages env3
129 ./env3/bin/pip install git-cola
132 Add the `env3/bin` directory to your `$PATH`, or symlink to `bin/git-cola` from
133 somewhere in your `$PATH` such as `~/.local/bin/git-cola`, and you can launch
134 Git Cola like any other built-in `git` command:
140 ## Install into a Python Virtualenv from Source
142 If you don't have PyQt installed then the easiest way to get it is to use a Python
143 virtualenv and install Git Cola into it in "editable" mode. This install method
144 lets you upgrade Git Cola by running `git pull`.
146 # Create a virtualenv called "env3" and activate it.
147 python3 -m venv --system-site-packages env3
148 source env3/bin/activate
150 # One-time setup: install optional requirements for development.
151 make requirements-dev requirements-optional
153 # Install git-cola in "editable" mode so that it uses the source tree.
156 # Run Git Cola via the "git-cola" Git subcommand.
160 If you add `env3/bin` (or symlink to `bin/git-cola` ) to your `$PATH` then you can
161 run `git cola` as if it were a builtin `git` command from outside of the virtualenv
162 (eg. after running "deactivate" or when opening a new shell).
165 ## Standalone Installation from Source
167 Running `make install prefix=$HOME/.local` will install Git Cola in your
168 `$HOME/.local` directory (`$HOME/.local/bin/git-cola`, `$HOME/.local/lib`, etc).
170 This installation method assumes that the `qtpy` and `PyQt*` dependencies have
173 The `Makefile` also supports `DESTDIR` to support creating packages for Linux package
176 make DESTDIR=/tmp/stage prefix=/usr/local install
181 For most end-users we recommend using either Homebrew or installing into
182 a Python virtualenv as described above.
184 You can install Git Cola from source using the same steps as above.
188 An easy way to install Git Cola is to use [Homebrew](https://brew.sh/) .
189 Use Homebrew to install the git-cola recipe:
191 brew install git-cola
193 If you install using Homebrew you can stop at this step.
194 You don't need to clone the repo or anything.
198 If you have all of the dependencies installed, either via `pip` or `brew` then
199 you can build a shell `git-cola.app` app bundle wrapper for use in `/Applications`.
201 If you'd like to build a `git-cola.app` bundle for `/Applications` run this command:
205 You will need to periodically rebuild the app wrapper whenever Python is upgraded.
207 ### Updating macOS and Homebrew
209 Updating macOS can often break Homebrew-managed software.
211 If you upgrade your macOS version and Git Cola no longer runs then then it is
212 recommended that you re-install Git Cola's dependencies after upgrading.
214 A quick fix when upgrading to newer versions of XCode or macOS is to
217 brew reinstall pyqt@5
219 You may also need to relink your pyqt installation:
223 This is required when upgrading to a modern (post-10.11 El Capitan) Mac OS X.
224 Homebrew now bundles its own Python3 installation instead of using the
225 system-provided default Python.
227 If the "brew reinstall" command above does not work then re-installing from
228 scratch using the instructions below should get things back in shape.
233 # uninstall git-cola and its dependencies
234 brew uninstall git-cola
238 # re-install git-cola and its dependencies
239 brew install git-cola
244 IMPORTANT If you have a 64-bit machine, install the 64-bit versions only.
245 Do not mix 32-bit and 64-bit versions.
247 Download and install the following:
249 * [Git for Windows](https://git-for-windows.github.io/)
251 * [Git Cola](https://github.com/git-cola/git-cola/releases)
253 Once these are installed you can run Git Cola from the Start menu.
255 See "Windows (Continued)" below for more details.
260 Git Cola ships with an interactive rebase editor called `git-cola-sequence-editor`.
261 `git-cola-sequence-editor` is used to reorder and choose commits when rebasing.
262 Start an interactive rebase through the "Rebase" menu, or through the
263 `git cola rebase` sub-command to use the `git-cola-sequence-editor`:
265 git cola rebase @{upstream}
267 `git-cola-sequence-editor` can be launched independently of git cola by telling
268 `git rebase` to use it as its editor through the `GIT_SEQUENCE_EDITOR`
269 environment variable:
271 export GIT_SEQUENCE_EDITOR="$HOME/git-cola/bin/git-cola-sequence-editor"
272 git rebase -i @{upstream}
275 # Git Cola Sub-commands
277 The `git-cola` command exposes various sub-commands that allow you to quickly
278 launch tools that are available from within the git-cola interface.
279 For example, `git cola find` launches the file finder,
280 and `git cola grep` launches the grep tool.
282 See `git cola --help-commands` for the full list of commands.
284 $ git cola --help-commands
287 {cola,am,archive,branch,browse,config,
288 dag,diff,fetch,find,grep,merge,pull,push,
289 rebase,remote,search,stash,tag,version}
293 {cola,am,archive,branch,browse,config,
294 dag,diff,fetch,find,grep,merge,pull,push,
295 rebase,remote,search,stash,tag,version}
298 am apply patches using "git am"
299 archive save an archive
300 branch create a branch
301 browse browse repository
302 config edit configuration
309 pull pull remote branches
310 push push remote branches
311 rebase interactive rebase
313 search search commits
314 stash stash and unstash changes
316 version print the version
320 If you already have Git Cola's dependencies installed then you can
321 start `cola` as a Python module if you have the source code available.
327 The following commands should be run during development:
332 # Run tests and longer-running pylint and flake8 checks
335 # Run tests against multiple python interpreters using tox
338 The test suite can be found in the [test](test) directory.
340 Commits and pull requests are automatically tested for code quality
341 using [GitHub Actions](https://github.com/git-cola/git-cola/actions/workflows/main.yml).
343 Auto-format `cola/i18n/*.po` files before committing when updating translations:
347 When submitting patches, consult the
348 [contributing guidelines](CONTRIBUTING.md).
353 Git Cola installs its modules into the default Python site-packages directory
354 (eg. `lib/python3.7/site-packages`) using setuptools.
356 While end-users can use `pip install git-cola` to install Git Cola, distribution
357 packagers should use the `make prefix=/usr` install process. Git Cola's `Makefile` wraps
358 `pip install --prefix=<prefix>` to provide a packaging-friendly `make install` target.
361 # Windows (Continued)
363 ## Microsoft Visual C++ 2015 Redistributable
365 Earlier versions of Git Cola may have shipped without `vcruntime140.dll` and may
366 not run on machines that are missing this DLL.
368 To fix this, download the
369 [Microsoft Visual C++ 2015 Redistributable](https://www.microsoft.com/en-us/download/details.aspx?id=52685)
372 Git Cola v4.0.0 and newer include this DLL and do not require this to be installed
377 In order to develop Git Cola on Windows you will need to install
378 Python3 and pip. Install PyQt5 using `pip install PyQt5`
379 to make the PyQt5 bindings available to Python.
381 Once these are installed you can use `python.exe` to run
382 directly from the source tree. For example, from a Git Bash terminal:
384 /c/Python36/python.exe ./bin/git-cola
386 ## Multiple Python versions
388 If you have multiple versions of Python installed, the `contrib/win32/cola`
389 launcher script might choose the newer version instead of the python
390 that has PyQt installed. In order to resolve this, you can set the
391 `cola.pythonlocation` git configuration variable to tell cola where to
392 find python. For example:
394 git config --global cola.pythonlocation /c/Python39
396 ## Building Windows Installers
398 Windows installers are built using
400 * [Pynsist](https://pynsist.readthedocs.io/en/latest/).
402 * [NSIS](http://nsis.sourceforge.net/Main_Page) is also needed.
404 To build the installer using Pynsist run:
406 ./contrib/win32/run-pynsist.sh
408 This will generate an installer in `build/nsis/`.
410 ## Windows "History Browser" Configuration Upgrade
412 You may need to configure your history browser if you are upgrading from an
413 older version of Git Cola on Windows.
415 `gitk` was originally the default history browser, but `gitk` cannot be
416 launched as-is on Windows because `gitk` is a shell script.
418 If you are configured to use `gitk`, then change your configuration to
419 go through Git's `sh.exe` on Windows. Similarly, we must go through
420 `python.exe` if we want to use `git-dag`.
422 If you want to use gitk as your history browser open the
423 Preferences screen and change the history browser command to:
425 "C:/Program Files/Git/bin/sh.exe" --login -i C:/Git/bin/gitk
427 `git-dag` became the default history browser on Windows in `v2.3`, so new
428 users do not need to configure anything.
