Switch branches/tags

Name already in use

A tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Are you sure you want to create this branch?

I'm setting up the repo on a new machine. I remember facing this issue before, so why not just add a quick FAQ for future contributors?

Git Homepage CI Help Contribute to Open Source

This is the web application for the site. It is meant to be the first place a person new to Git will land and download or learn about the Git SCM system.

This app is written in Ruby on Rails and deployed on Heroku.


You'll need a Ruby environment to run Rails. First do:

$ rvm use .
$ bundle install

Then you need to create the database structure:

$ rake db:migrate

Alternatively you can run the script at script/bootstrap which will set up Ruby dependencies and the local SQLite database.

Now you'll want to populate the man pages. You can do so from a local Git source clone like this:

$ GIT_REPO=../git/.git rake local_index

This will populate the man pages for all Git versions. You can also populate them only for a specific Git version (faster):

$ version=v2.23.0
$ GIT_REPO=../git/.git REBUILD_DOC=$version rake local_index

Or you can populate the man pages from GitHub (much slower) like this:

$ export GITHUB_API_TOKEN=github_personal_auth_token
$ rake preindex  # all versions
$ REBUILD_DOC=$version rake preindex  # specific version

Similarly, you can also populate the localized man pages. From a local clone of :

$ GIT_REPO=../git-html-l10n/.git rake local_index_l10n  # all versions
$ GIT_REPO=../git-html-l10n/.git REBUILD_DOC=$version rake local_index_l10n  # specific version

Or you can do it from GitHub (much slower) like this:

$ export GITHUB_API_TOKEN=github_personal_auth_token
$ rake preindex_l10n  # all versions
$ REBUILD_DOC=$version rake preindex_l10n  # specific version

Now you need to get the latest downloads for the downloads pages:

$ rake downloads

Now you'll probably want some book data. You'll have to have access to the Pro Git project on GitHub through the API.

$ export GITHUB_API_TOKEN=github_personal_auth_token
$ rake remote_genbook2

If you have 2FA enabled, you'll need to create a Personal Access Token.

That will generate the book content from the Asciidoc files fetched from the online repository and post it to the Rails server database. You can select a specific language by indicating it in the GENLANG environment variable:

$ GENLANG=zh rake remote_genbook2

Alternatively, you can get the book content from a repository on your computer by specifying the path in the GENPATH environment variable to the local_genbook2 target:

$ GENLANG=fr GENPATH=../progit2-fr rake local_genbook2

Now you can run the Rails site to take a look.

$ ./script/server

The site should be running on http://localhost:5000


To run the tests for this project, run:

$ rspec

To run the website for testing purposes, run:

$ ./script/server


If you wish to contribute to this website, please fork it on GitHub, push your change to a named branch, then send a pull request. If it is a big feature, you might want to start an issue first to make sure it's something that will be accepted. If it involves code, please also write tests for it.

Adding new GUI

The list of GUI clients has been constructed by the community for a long time. If you want to add another tool you'll need to follow a few steps:

  1. Add the GUI client details at the YAML file:

    1. The fields name, url, price, license should be very straightforward to fill.
    2. The field image_tag corresponds to the filename of the image of the tool (without path, just the filename).
    3. platforms is a list of at least 1 platform in which the tool is supported. The possibilities are: Windows, Mac, Linux, Android, and iOS
    4. order can be filled with the biggest number already existing, plus 1 (Adding to the bottom - this will be covered in the following steps)
    5. trend_name is an optional field that can be used for helping sorting the clients (also covered in the next steps)
  2. Add the image to public/images/guis/<GUI_CLIENT_NAME>@2x.png and public/images/guis/<GUI_CLIENT_NAME>.png making sure the aspect ratio matches a 588:332 image.

  3. Sort the tools

    1. From the root of the repository, run: $ ./script/sort-gui
    2. A list of google trends url's will be displayed at the bottom if everything went well.
    3. Open each and check if the clients are sorted.
    4. If the clients are not sorted, just fix the order (by changing the order field), bubbling the more 'known' clients all the way up.
    5. Repeat until the order stabilizes.
    6. It is possible that your new GUI client doesn't have good results in Google Trends. You can try similar terms (for instance, adding the git keyword sometime helps). If you find any similar term that returns better results, add the trend_name field to the GUI client. Have a look at the Tower and Cycligent Git Tool tools example.
    7. The script makes some basic verifications. If there was some problem, it should be easily visible in the output
    8. If you have more than 1 tool with the same name, a warning will appear: ======= WARNING: THERE ARE DUPLICATED GUIS =======
    9. If you are using the same order value for more than 1 tool, a warning will appear: ======= WARNING: THERE ARE DUPLICATED ORDERS (value: <VALUE>) =======


While setting the repo if you find any error, check if it's a known issue and the corresponding solution bellow.

An error occurred while installing pg (1.2.3), and Bundler cannot continue.

If you got this error when running bundle install, then you need to install postgresql on your OS. Check this stackoverflow topic for more details.
