cli: add command 'kallithea-cli front-end-build'
Kallithea is under the GPL license, and we can thus only distribute any
generated code if we also ship the corresponding source.
We are moving towards a web front-end that use npm to download and compile
various open source components. The components might not be GPL, but if we
distribute any parts of their code (compiled or converted to other
representation), then we also must distribute the corresponding source under
the GPL.
It doesn't seem feasible for us to distribute the source of everything that
npm downloads and includes when we are building. It thus also doesn't seem
feasible for us to build and ship the compiled (possibly minified) front-end
code. Instead, we have to make it as smooth as possible for our users to
get up and running.
It doesn't seem feasible for us to ship or install npm. We must assume it is
available. That requirement must be documented clearly, and we must recommend
how to install npm for the most common platforms.
We could perhaps just document what manual steps to run. Kallithea doesn't
work out of the box anyway - it has to be configured and initialized. Extra
steps might not be a big problem.
Another approach is to call out to npm while pip is installing Kallithea and
download the requirements and build the files. It can be done by customizing
setuptools commands in setup.py. But: Python packaging is fragile. Even
though we only support pip, it really isn't built for things like this.
Custom output is muted and buffered and only shown if running with -v or the
command fails. And pip and setup.py can be used to build and install in so
many ways that we probably can't make it work reliably with all ways of
installing Kallithea.
The approach implemented by this commit is to add a custom cli command
'front-end-build' to run the required commands. This single user-facing
command can internally run various steps as needed. The only current
requirement is the presence of npm and an internet connection.
For now, this will just create/update style.css ... but currently probably
without any actual changes. The files created by npm (and the node_modules
directory) must *not* be a part of the release package made with 'setup.py
sdist'.

==========================
Installation on Unix/Linux
==========================
The following describes three different ways of installing Kallithea:
- :ref:`installation-source`: The simplest way to keep the installation
up-to-date and track any local customizations is to run directly from
source in a Kallithea repository clone, preferably inside a virtualenv
virtual Python environment.
- :ref:`installation-virtualenv`: If you prefer to only use released versions
of Kallithea, the recommended method is to install Kallithea in a virtual
Python environment using `virtualenv`. The advantages of this method over
direct installation is that Kallithea and its dependencies are completely
contained inside the virtualenv (which also means you can have multiple
installations side by side or remove it entirely by just removing the
virtualenv directory) and does not require root privileges.
- :ref:`installation-without-virtualenv`: The alternative method of installing
a Kallithea release is using standard pip. The package will be installed in
the same location as all other Python packages you have ever installed. As a
result, removing it is not as straightforward as with a virtualenv, as you'd
have to remove its dependencies manually and make sure that they are not
needed by other packages.
Regardless of the installation method you may need to make sure you have
appropriate development packages installed, as installation of some of the
Kallithea dependencies requires a working C compiler and libffi library
headers. Depending on your configuration, you may also need to install
Git and development packages for the database of your choice.
For Debian and Ubuntu, the following command will ensure that a reasonable
set of dependencies is installed::
sudo apt-get install build-essential git python-pip python-virtualenv libffi-dev python-dev
For Fedora and RHEL-derivatives, the following command will ensure that a
reasonable set of dependencies is installed::
sudo yum install gcc git python-pip python-virtualenv libffi-devel python-devel
.. _installation-source:
Installation from repository source
-----------------------------------
To install Kallithea in a virtualenv_ using the stable branch of the development
repository, follow the instructions below::
hg clone https://kallithea-scm.org/repos/kallithea -u stable
cd kallithea
virtualenv ../kallithea-venv
. ../kallithea-venv/bin/activate
pip install --upgrade pip setuptools
pip install --upgrade -e .
python2 setup.py compile_catalog # for translation of the UI
You can now proceed to :ref:`setup`.
.. _installation-virtualenv:
Installing a released version in a virtualenv
---------------------------------------------
It is highly recommended to use a separate virtualenv_ for installing Kallithea.
This way, all libraries required by Kallithea will be installed separately from your
main Python installation and other applications and things will be less
problematic when upgrading the system or Kallithea.
An additional benefit of virtualenv_ is that it doesn't require root privileges.
- Assuming you have installed virtualenv_, create a new virtual environment
for example, in `/srv/kallithea/venv`, using the virtualenv command::
virtualenv /srv/kallithea/venv
- Activate the virtualenv_ in your current shell session and make sure the
basic requirements are up-to-date by running::
. /srv/kallithea/venv/bin/activate
pip install --upgrade pip setuptools
.. note:: You can't use UNIX ``sudo`` to source the ``virtualenv`` script; it
will "activate" a shell that terminates immediately. It is also perfectly
acceptable (and desirable) to create a virtualenv as a normal user.
.. note:: Some dependencies are optional. If you need them, install them in
the virtualenv too::
pip install --upgrade psycopg2
pip install --upgrade python-ldap
This might require installation of development packages using your
distribution's package manager.
- Make a folder for Kallithea data files, and configuration somewhere on the
filesystem. For example::
mkdir /srv/kallithea
- Go into the created directory and run this command to install Kallithea::
pip install --upgrade kallithea
Alternatively, download a .tar.gz from http://pypi.python.org/pypi/Kallithea,
extract it and run::
pip install --upgrade .
- This will install Kallithea together with all other required
Python libraries into the activated virtualenv.
You can now proceed to :ref:`setup`.
.. _installation-without-virtualenv:
Installing a released version without virtualenv
------------------------------------------------
For installation without virtualenv, 'just' use::
pip install kallithea
Note that this method requires root privileges and will install packages
globally without using the system's package manager.
To install as a regular user in ``~/.local``, you can use::
pip install --user kallithea
You can now proceed to :ref:`setup`.
