.. _vcs: Version control integration =========================== Weblate currently supports :ref:`vcs-git` (with extended support for :ref:`vcs-github`) and :ref:`vcs-mercurial` as version control backends. .. _vcs-repos: Accessing repositories ---------------------- The VCS repository you want to use has to be accessible to Weblate. With a publicly available repository you just need to enter correct URL (for example ``git://github.com/WeblateOrg/weblate.git`` or ``https://github.com/WeblateOrg/weblate.git``), but for private repositories the setup might be more complex. .. _internal-urls: Weblate internal URLs +++++++++++++++++++++ To share one repository between different components you can use a special URL like ``weblate://project/component``. This way, the component will share the VCS repository configuration with referenced component and the VCS repository will be stored just once on the disk. SSH repositories ++++++++++++++++ The most frequently used method to access private repositories is based on SSH. To have access to such a repository, you generate SSH key for Weblate and authorize it to access the repository. Weblate also needs to know the host key to avoid man in the middle attacks. This all can be done in the Weblate administration interface: .. image:: images/ssh-keys.png Generating SSH keys ~~~~~~~~~~~~~~~~~~~ You can generate or display the key currently used by Weblate in the admin interface (follow :guilabel:`SSH keys` link on main admin page). Once you've done this, Weblate should be able to access your repository. .. note:: The keys need to be without password to make it work, so be sure they are well protected against malicious usage. .. warning:: On GitHub, you can add the key to only one repository. See the following sections for other solutions for GitHub. Verifying SSH host keys ~~~~~~~~~~~~~~~~~~~~~~~ Before connecting to the repository, you also need to verify SSH host keys of servers you are going to access in the same section of the admin interface. You can do this in the :guilabel:`Add host key` section. Just enter hostname you are going to access (eg. ``gitlab.com``) and press :guilabel:`Submit`. After adding it please verify that the fingerprint matches the server you're adding, the fingerprints will be displayed in the confirmation message: .. image:: images/ssh-keys-added.png HTTPS repositories ++++++++++++++++++ To access protected HTTPS repositories, you need to include the username and password in the URL. Don't worry, Weblate will strip this information when showing the URL to the users (if they are allowed to see the repository URL at all). For example the GitHub URL with authentication might look like ``https://user:your_access_token@github.com/WeblateOrg/weblate.git``. .. note:: In case your username or password contains special chars, those have to be URL encoded, for example ``https://user%40example.com:%24password%23@bitbucket.org/...```. Using proxy +++++++++++ If you need to access http/https VCS repositories using a proxy server, you need to configure the VCS to use it. This can be configured using the ``http_proxy``, ``https_proxy``, and ``all_proxy`` environment variables (check cURL documentation for more details) or by enforcing it in VCS configuration, for example: .. code-block:: sh git config --global http.proxy http://user:password@proxy.example.com:80 .. note:: The proxy setting needs to be done in the same context which is used to execute Weblate. For the environment it should be set for both server and cron jobs. The VCS configuration has to be set for the user which is running Weblate. .. seealso:: `curl manpage `_, `git config documentation `_ .. _vcs-git: Git --- Git is first VCS backend that was available in Weblate and is still the most stable and tested one. .. seealso:: See :ref:`vcs-repos` for information how to access different kind of repositories. .. _vcs-repos-github: GitHub repositories +++++++++++++++++++ You can access GitHub repositories by SSH as mentioned above, but in case you need to access more repositories, you will hit a GitHub limitation on the SSH key usage (one key can be used only for one repository). There are several ways to work around this limitation. For smaller deployments, you can use HTTPS authentication using a personal access token and your account, see `Creating an access token for command-line use`_. .. _Creating an access token for command-line use: https://help.github.com/articles/creating-an-access-token-for-command-line-use/ For a bigger setup, it is usually better to create dedicated user for Weblate, assign him the SSH key generated in Weblate and grant him access to all repositories you want. .. _vcs-git-helpers: Git remote helpers ++++++++++++++++++ You can also use Git `remote helpers`_ for supporting other VCS as well, but this usually leads to other problems, so be prepared to debug them. At this time, helpers for Bazaar and Mercurial are available within separate repositories on GitHub: `git-remote-hg`_ and `git-remote-bzr`_. You can download them manually and put somewhere in your search path (for example :file:`~/bin`). You also need to have installed appropriate version control programs as well. Once you have these installed, you can use such remotes to specify repository in Weblate. To clone ``gnuhello`` project from Launchpad with Bazaar use:: bzr::lp:gnuhello For ``hello`` repository from selenic.com with Mercurial use:: hg::http://selenic.com/repo/hello .. _remote helpers: https://git-scm.com/docs/git-remote-helpers .. _git-remote-hg: https://github.com/felipec/git-remote-hg .. _git-remote-bzr: https://github.com/felipec/git-remote-bzr .. warning:: Please be prepared to some inconvenience when using Git remote helpers, for example with Mercurial, the remote helper sometimes tends to create new tip when pushing changes back. .. _vcs-github: GitHub ------ .. versionadded:: 2.3 This just adds a thin layer on top of :ref:`vcs-git` to allow push translation changes as pull requests instead of pushing directory to the repository. It currently uses the `hub`_ tool to do the integration. There is no need to use this to access Git repositories, ordinary :ref:`vcs-git` works the same, the only difference is how pushing to a repository is handled. With :ref:`vcs-git` changes are pushed directly to the repository, while :ref:`vcs-github` creates pull requests. .. _github-push: Pushing changes to GitHub as pull request +++++++++++++++++++++++++++++++++++++++++ If you are translating a project that's hosted on GitHub and don't want to push translations to the repository, you can have them sent as a pull request instead. You need to configure the `hub`_ command line tool and set :setting:`GITHUB_USERNAME` for this to work. .. seealso:: :setting:`GITHUB_USERNAME`, :ref:`hub-setup` for configuration instructions .. _hub-setup: Setting up hub ++++++++++++++ :ref:`github-push` requires a configured `hub`_ installation on your server. Follow the installation instructions at https://hub.github.com/ and perform an action with `hub`_ to finish the configuration, for example: .. code-block:: sh HOME=${DATA_DIR}/home hub clone octocat/Spoon-Knife The `hub`_ will ask you for your GitHub credentials, retrieve a token and store it into :file:`~/.config/hub`. .. note:: Use the username you configured :guilabel:`hub` with as :setting:`GITHUB_USERNAME`. .. _hub: https://hub.github.com/ .. _vcs-mercurial: Mercurial --------- .. versionadded:: 2.1 Mercurial is another VCS you can use directly in Weblate. .. note:: It should work with any Mercurial version, but there are sometimes incompatible changes to the command line interface which break Weblate. .. seealso:: See :ref:`vcs-repos` for information how to access different kind of repositories. .. _vcs-git-svn: Subversion ---------- .. versionadded:: 2.8 Thanks to `git-svn`_, Weblate can work with `subversion`_ repositories. Git-svn is a Perl script that enables the usage of subversion with a git client, enabling users to have a full clone of the internal repository and commit locally. .. note:: Weblate tries to detect Subversion repository layout automatically - it supports both direct URLs for branch or repositories with standard layout (branches/, tags/ and trunk/). See `git-svn documentation `_ for more information. .. versionchanged:: 2.19 In older versions only repositories with standard layout were supported. .. _git-svn: https://git-scm.com/docs/git-svn .. _subversion: https://subversion.apache.org/ Subversion Credentials ++++++++++++++++++++++ Weblate expects you to have accepted the certificate upfront and inserted your credential, if needed. It will look into the DATA_DIR directory. To insert your credential and accept the certificate, you can run svn once with the `$HOME` environment variable set to the DATA_DIR:: HOME=${DATA_DIR}/home svn co https://svn.example.com/example .. seealso:: :setting:`DATA_DIR`
