39 * [QtPy](https://github.com/spyder-ide/qtpy) 1.1.0 or newer.
41 Git Cola uses QtPy, so you can choose between PyQt5 and PySide2 by setting
42 the `QT_API` environment variable to `pyqt5` or `pyside2` as desired.
43 `qtpy` defaults to `pyqt5` and falls back to `pyside2` if `pyqt5` is not installed.
45 Any of the following Python Qt libraries must be installed:
47 * [PyQt5](https://www.riverbankcomputing.com/software/pyqt/download5)
50 * [PySide2](https://github.com/PySide/PySide)
56 Git Cola enables additional features when the following
57 Python modules are installed.
59 [send2trash](https://github.com/hsoft/send2trash) enables cross-platform
60 "Send to Trash" functionality.
65 **IMPORTANT**: never run `pip install` as root or outside of a Python virtualenv!
67 You can install the latest released version using `pip`:
70 ./env3/bin/pip install git-cola
73 Add the `env3/bin` directory to your `$PATH` (or symlink to `bin/git-cola` from somewhere
74 in your `$PATH`) allows you to launch Git Cola like any other built-in `git` command:
79 ## Python Virtual Environments
81 If you don't have PyQt installed then the easiest way to get it is to use a Python
82 virtualenv and install Git Cola into it in "editable" mode so that you can "upgrade"
83 Git Cola by running `git pull`.
85 # Create a virtualenv called "env3" and activate it.
87 source env3/bin/activate
89 # One-time setup: install optional requirements for development.
90 make requirements-dev requirements-optional
92 # Install git-cola in "editable" mode so that it uses the source tree.
95 # Run Git Cola via the "git-cola" Git subcommand.
98 If you add `env3/bin` (or symlink to `bin/git-cola` ) to your `$PATH` then you can
99 run `git cola` as if it were a builtin `git` command.
101 ## Standalone Installation
103 Running `make install` will install Git Cola in your `$HOME` directory
104 (`$HOME/bin/git-cola`, `$HOME/lib`, etc).
106 If you want to do a global install you can do
108 make prefix=/usr/local install
110 The `Makefile` also supports `DESTDIR`:
112 make DESTDIR=/tmp/stage prefix=/usr/local install
116 Linux is it! Your distro has probably already packaged `git-cola`.
117 If not, please file a bug against your distribution ;-)
121 Available in the [AUR](https://aur.archlinux.org/packages/git-cola/).
137 zypper install git-cola
141 Available in [SlackBuilds.org](http://slackbuilds.org/result/?search=git-cola).
145 [See here](https://packages.ubuntu.com/search?keywords=git-cola) for the
146 versions that are available in Ubuntu's repositories.
148 There was a [PPA by @pavreh](https://launchpad.net/~pavreh/+archive/ubuntu/git-cola)
149 but it has not been updated for a while.
154 # Install from official binary packages
155 pkg install -r FreeBSD devel/git-cola
158 cd /usr/ports/devel/git-cola && make clean install
163 For most end-users we recommend using either Homebrew or `pip install git-cola`
164 inside of a virtualenv.
166 You can install Git Cola using the same `Makefile` steps above to install from source.
170 An easy way to install Git Cola is to use [Homebrew](https://brew.sh/) .
171 Use Homebrew to install the git-cola recipe:
173 brew install git-cola
175 If you install using Homebrew you can stop at this step.
176 You don't need to clone the repo or anything.
180 If you have all of the dependencies installed, either via `pip` or `brew` then
181 you can build a shell `git-cola.app` app bundle wrapper for use in `/Applications`.
183 If you'd like to build a `git-cola.app` bundle for `/Applications` run this command:
187 You will need to periodically rebuild the app wrapper whenever Python is upgraded.
189 ### Updating macOS and Homebrew
191 Updating macOS can often break Homebrew-managed software.
193 If you upgrade your macOS version and Git Cola no longer runs then then it is
194 recommended that you re-install Git Cola's dependencies after upgrading.
196 A quick fix when upgrading to newer versions of XCode or macOS is to
199 brew reinstall pyqt@5
201 You may also need to relink your pyqt installation:
205 This is required when upgrading to a modern (post-10.11 El Capitan) Mac OS X.
206 Homebrew now bundles its own Python3 installation instead of using the
207 system-provided default Python.
209 If the "brew reinstall" command above does not work then re-installing from
210 scratch using the instructions below should get things back in shape.
215 # uninstall git-cola and its dependencies
216 brew uninstall git-cola
220 # re-install git-cola and its dependencies
221 brew install git-cola
226 IMPORTANT If you have a 64-bit machine, install the 64-bit versions only.
227 Do not mix 32-bit and 64-bit versions.
229 Download and install the following:
231 * [Git for Windows](https://git-for-windows.github.io/)
233 * [Git Cola](https://github.com/git-cola/git-cola/releases)
235 Once these are installed you can run Git Cola from the Start menu.
237 See "Windows (Continued)" below for more details.
242 Git Cola ships with an interactive rebase editor called `git-cola-sequence-editor`.
243 `git-cola-sequence-editor` is used to reorder and choose commits when rebasing.
244 Start an interactive rebase through the "Rebase" menu, or through the
245 `git cola rebase` sub-command to use the `git-cola-sequence-editor`:
247 git cola rebase @{upstream}
249 `git-cola-sequence-editor` can be launched independently of git cola by telling
250 `git rebase` to use it as its editor through the `GIT_SEQUENCE_EDITOR`
251 environment variable:
253 export GIT_SEQUENCE_EDITOR="$HOME/git-cola/bin/git-cola-sequence-editor"
254 git rebase -i @{upstream}
257 # Git Cola Sub-commands
259 The `git-cola` command exposes various sub-commands that allow you to quickly
260 launch tools that are available from within the git-cola interface.
261 For example, `git cola find` launches the file finder,
262 and `git cola grep` launches the grep tool.
264 See `git cola --help-commands` for the full list of commands.
266 $ git cola --help-commands
269 {cola,am,archive,branch,browse,config,
270 dag,diff,fetch,find,grep,merge,pull,push,
271 rebase,remote,search,stash,tag,version}
275 {cola,am,archive,branch,browse,config,
276 dag,diff,fetch,find,grep,merge,pull,push,
277 rebase,remote,search,stash,tag,version}
280 am apply patches using "git am"
281 archive save an archive
282 branch create a branch
283 browse browse repository
284 config edit configuration
291 pull pull remote branches
292 push push remote branches
293 rebase interactive rebase
295 search search commits
296 stash stash and unstash changes
298 version print the version
302 If you already have Git Cola's dependencies installed then you can
303 start `cola` as a Python module if you have the source code available.
309 The following commands should be run during development:
314 # Run tests and longer-running pylint and flake8 checks
317 # Run tests against multiple python interpreters using tox
320 The test suite can be found in the [test](test) directory.
322 Commits and pull requests are automatically tested for code quality
323 using [GitHub Actions](https://github.com/git-cola/git-cola/actions/workflows/main.yml).
325 Auto-format `cola/i18n/*.po` files before committing when updating translations:
329 When submitting patches, consult the
330 [contributing guidelines](CONTRIBUTING.md).
335 Git Cola installs its modules into the default Python site-packages directory
336 (eg. `lib/python3.7/site-packages`) using setuptools.
338 While end-users can use `pip install git-cola` to install Git Cola, distribution
339 packagers should use the `make prefix=/usr` install process. Git Cola's `Makefile` wraps
340 `pip install --prefix=<prefix>` to provide a packaging-friendly `make install` target.
343 # Windows (Continued)
345 ## Microsoft Visual C++ 2015 Redistributable
347 Earlier versions of Git Cola may have shipped without `vcruntime140.dll` and may
348 not run on machines that are missing this DLL.
350 To fix this, download the
351 [Microsoft Visual C++ 2015 Redistributable](https://www.microsoft.com/en-us/download/details.aspx?id=52685)
354 Git Cola v4.0.0 and newer include this DLL and do not require this to be installed
359 In order to develop Git Cola on Windows you will need to install
360 Python3 and pip. Install PyQt5 using `pip install PyQt5`
361 to make the PyQt5 bindings available to Python.
363 Once these are installed you can use `python.exe` to run
364 directly from the source tree. For example, from a Git Bash terminal:
366 /c/Python36/python.exe ./bin/git-cola
368 ## Multiple Python versions
370 If you have multiple versions of Python installed, the `contrib/win32/cola`
371 launcher script might choose the newer version instead of the python
372 that has PyQt installed. In order to resolve this, you can set the
373 `cola.pythonlocation` git configuration variable to tell cola where to
374 find python. For example:
376 git config --global cola.pythonlocation /c/Python39
378 ## Building Windows Installers
380 Windows installers are built using
382 * [Pynsist](https://pynsist.readthedocs.io/en/latest/).
384 * [NSIS](http://nsis.sourceforge.net/Main_Page) is also needed.
386 To build the installer using Pynsist run:
388 ./contrib/win32/run-pynsist.sh
390 This will generate an installer in `build/nsis/`.
392 ## Windows "History Browser" Configuration Upgrade
394 You may need to configure your history browser if you are upgrading from an
395 older version of Git Cola on Windows.
397 `gitk` was originally the default history browser, but `gitk` cannot be
398 launched as-is on Windows because `gitk` is a shell script.
400 If you are configured to use `gitk`, then change your configuration to
401 go through Git's `sh.exe` on Windows. Similarly, we must go through
402 `python.exe` if we want to use `git-dag`.
404 If you want to use gitk as your history browser open the
405 Preferences screen and change the history browser command to:
407 "C:/Program Files/Git/bin/sh.exe" --login -i C:/Git/bin/gitk
409 `git-dag` became the default history browser on Windows in `v2.3`, so new
410 users do not need to configure anything.
