This article provides a practical example of contributing changes to Osm Framework and other osmphp/* GitHub repositories. It's based on the Osm_Project application pull request.



Send bug fixes, and minor features to the current release branch. Prefix commit messages with fix: and minor:, respectively:

GitHub Current Branch

Send major new features should always be sent to the upcoming release branch ( for v0.10 current release, it's v0.11; for v2, it's v3, and so on). Prefix commit messages with major:.

In case the upcoming release branch doesn't exist yet, ask maintainer to create it in repository Discussions.


  1. Use "Fork" button to fork the relevant repository (in our example, it's osmphp/core) into your account (in my case, osmianski).

  2. Clone the repository to your computer using git clone command:

    git clone
  3. Implement changes on a new branch with a meaningful name. Write unit tests in order to make sure that future changes made by other contributors won't break yours.

  4. Commit and push the changes to your fork:

    git add .
    git commit -am "major: new `Osm_Project` application"
    git push
  5. Create new pull request in the original repository, click compare across forks. In base repository, pick current or upcoming branch of the original repository. In head repository, pick the branch you made changes on. Click Create pull request, enter description, and click Create pull request again. See also Creating a pull request from a fork.

Note. The workflow is the same if you have write access to the original repository, just don't create a fork, and work in the original repository instead.

Using The Fork In Your Project

While the maintainer reviews and merges your pull request, you can use your fork instead of original repository in your project. Instruct Composer to use the fork, and your branch in the project's composer.json, and run composer update:

    "require": {
        "osmphp/core": "v0.8.x-dev"
    "repositories": [
            "type": "vcs",
            "url": ""

Note. v0.8.x-dev version constraint in composer.json stands for v0.8 Git branch. For more information, read about Composer branch constraints.
