# NUTRITIONAL FACTS
## ACTIVE INGREDIENTS
* [git](http://git-scm.com/) 1.6.3 or newer.
* [Python](http://python.org/) 2.6, 2.7, and 3.2 or newer.
* [QtPy](https://github.com/spyder-ide/qtpy) 1.1.0 or newer.
* [argparse](https://pypi.python.org/pypi/argparse) 1.1 or newer.
argparse is part of the stdlib in Python 2.7; install argparse separately if
you are running on Python 2.6.
* [Sphinx](http://sphinx-doc.org/) for building the documentation.
*git-cola* uses *QtPy*, so you can choose between *PyQt4*, *PyQt5*, and
*PySide* by setting the `QT_API` environment variable to `pyqt4`, `pyqt5` or
`pyside` as desired. `qtpy` defaults to `pyqt5` and falls back to `pyqt4`
if `pyqt5` is not installed.
Any of the following Python Qt libraries must be installed:
* [PyQt4](http://www.riverbankcomputing.co.uk/software/pyqt/download)
4.6 or newer
* [PyQt5](http://www.riverbankcomputing.co.uk/software/pyqt/download5)
5.2 or newer
* [PySide](https://github.com/PySide/PySide)
1.1.0 or newer
*NOTE*: We do not yet recommend using *PyQt5* because there are known
exit-on-segfault bugs in *Qt5* that have not yet been addressed.
*git-cola* is sensitive to this bug and is known to crash on exit
when using `git dag` or the interactive rebase feature on *PyQt5*.
[QTBUG-52988](https://bugreports.qt.io/browse/QTBUG-52988)
*PyQt4* is stable and there are no known issues when using it so we recommend
using *PyQt4* until the *Qt5* bugs have been resolved.
Set `QT_API=pyqt4` in your environment if you have both
versions of *PyQt* installed and want to ensure that PyQt4 is used.
*NOTE*: *git-cola* includes a vendored copy of its *QtPy* dependency.
We provide a copy of the `qtpy` module when installing *git-cola* so that you
are not required to install *QtPy* separately. If you'd like to provide your
own `qtpy` module, for example from the `python-qtpy` Debian package, then use
`make NO_VENDOR_LIBS=1 ...` when invoking `make`, or export
`GIT_COLA_NO_VENDOR_LIBS=1` into the build environment.
## ADDITIVES
*git-cola* enables additional features when the following
Python modules are installed.
[send2trash](https://github.com/hsoft/send2trash) enables cross-platform
"Send to Trash" functionality.
# BREWING INSTRUCTIONS
## RUN FROM SOURCE
You don't need to install *git-cola* to run it.
Running *git-cola* from its source tree is the easiest
way to try the latest version.
git clone git://github.com/git-cola/git-cola.git
cd git-cola
./bin/git-cola
./bin/git-dag
Having *git-cola*'s *bin/* directory in your path allows you to run
*git cola* like a regular built-in Git command:
# Replace "$PWD/bin" with the path to git-cola's bin/ directory
PATH="$PWD/bin":"$PATH"
export PATH
git cola
git dag
The instructions below assume that you have *git-cola* present in your
`$PATH`. Replace "git cola" with "./bin/git-cola" as needed if you'd like to
just run it in-place.
# INSTALLATION
Normally you can just do "make install" to install *git-cola*
in your `$HOME` directory (`$HOME/bin`, `$HOME/share`, etc).
If you want to do a global install you can do
make prefix=/usr install
The platform-specific installation methods below use the native
package manager. You should use one of these so that all of *git-cola*'s
dependencies are installed.
## LINUX
Linux is it! Your distro has probably already packaged git-cola.
If not, please file a bug against your distribution ;-)
### arch
yaourt -S git-cola
### debian, ubuntu
apt-get install git-cola
### fedora
dnf install git-cola
### gentoo
emerge git-cola
### opensuse
Use the [one-click install link](http://software.opensuse.org/package/git-cola).
## MAC OS X
Before setting up homebrew, use
[pip](https://pip.readthedocs.io/en/latest/installing.html) to install
[sphinx](http://sphinx-doc.org/latest/install.html).
Sphinx is used to build the documentation.
sudo pip install --requirement requirements.txt
[Homebrew](http://mxcl.github.com/homebrew/) is the easiest way to install
git-cola's *Qt4* and *PyQt4* dependencies. We will use homebrew to install
the git-cola recipe, but build our own .app bundle from source.
brew install git-cola
Once brew has installed git-cola you can:
1. Clone git-cola
`git clone git://github.com/git-cola/git-cola.git && cd git-cola`
2. Build the git-cola.app application bundle
`make git-cola.app`
3. Copy it to _/Applications_
`rm -fr /Applications/git-cola.app && cp -r git-cola.app /Applications`
## WINDOWS INSTALLATION
Download the latest stable Git, Python 2.x, and Py2x-PyQt4 installers
* [msysGit](http://msysgit.github.com/)
* [Python](http://python.org/download/)
* [PyQt](http://www.riverbankcomputing.co.uk/software/pyqt/download/)
* [git-cola Installer](https://github.com/git-cola/git-cola/downloads)
Once these are installed you can run *git-cola* from the Start menu or
by double-clicking on the `git-cola.pyw` script.
If you are developing *git-cola* on Windows you can use `python.exe` to run
*git-cola* directly from source.
python.exe ./bin/git-cola
See "WINDOWS (continued)" below for more details.

# GOODIES
*git-cola* ships with an interactive rebase editor called *git-xbase*.
*git-xbase* can be used to reorder and choose commits and is typically
launched through the *git-cola*'s "Rebase" menu.
*git-xbase* can also be launched independently of the main *git-cola* interface
by telling `git rebase` to use it as its editor:
env GIT_SEQUENCE_EDITOR="$PWD/share/git-cola/bin/git-xbase" \
git rebase -i origin/master
The quickest way to launch *git-xbase* is via the *git cola rebase*
sub-command (as well as various other sub-commands):
git cola rebase origin/master
# COMMAND-LINE TOOLS
The *git-cola* command exposes various sub-commands that allow you to quickly
launch tools that are available from within the *git-cola* interface.
For example, `./bin/git-cola find` launches the file finder,
and `./bin/git-cola grep` launches the grep tool.
See `git cola --help-commands` for the full list of commands.
$ git cola --help-commands
usage: git-cola [-h]
{cola,am,archive,branch,browse,classic,config,
dag,diff,fetch,find,grep,merge,pull,push,
rebase,remote,search,stash,tag,version}
...
valid commands:
{cola,am,archive,branch,browse,classic,config,

## HACKING
The following commands should be run during development:
# Run the unit tests
$ make test
# Check for pylint warnings. All new code must pass 100%.
$ make pylint
The test suite can be found in the [test](test) directory.
The tests are setup to run automatically when code is pushed using
[Travis CI](https://travis-ci.org/git-cola/git-cola).
Checkout the [Travis config file](.travis.yml) for more details.
When submitting patches, consult the [contributing guidelines](CONTRIBUTING.md).
# WINDOWS (continued)
## WINDOWS-ONLY HISTORY BROWSER CONFIGURATION UPGRADE
You may need to configure your history browser if you are upgrading from an
older version of *git-cola*.
`gitk` was originally the default history browser, but `gitk` cannot be
launched as-is on Windows because `gitk` is a shell script.
If you are configured to use `gitk`, then change your configuration to
go through Git's `sh.exe` on Windows. Similarly,we must go through
`python.exe` if we want to use `git-dag`.
If you want to use *gitk* as your history browser open the
*Preferences* screen and change the history browser command to:
C:/Git/bin/sh.exe --login -i C:/Git/bin/gitk
Alternatively, if you'd like to use *git-dag* as your history browser, use:
C:/Python27/python.exe C:/git-cola/bin/git-dag
*git-dag* became the default history browser on Windows in `v2.3`, so new
users should not need to configure anything.
# BUILDING WINDOWS INSTALLERS
Windows installers are built using
* [Pynsist](http://pynsist.readthedocs.io/en/latest/).
* [NSIS](http://nsis.sourceforge.net/Main_Page) is also needed.
To build the installer using *Pynsist*:
* If building from a non-Windows platform run
`./contrib/win32/fetch_pyqt_windows.sh`.
This will download a PyQt binary installer for Windows and unpack its files
into `pynsist_pkgs/`.
* Run `pynsist pynsist.cfg`.
The installer will be built in `build/nsis/`.
Before *Pynsist*, installers were built using *InnoSetup*.
The *InnoSetup* scripts are still available:
./contrib/win32/create-installer.sh
You have to make sure that the file */share/InnoSetup/ISCC.exe* exists.
