This page should provide you with some basic information if you're thinking about contributing to FAKE.
This page can be edited by sending a pull request to the FAKE project on GitHub, so if you learn something when playing with FAKE please record your findings here!
Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the Project shall be under the terms and conditions of the Apache 2.0 license. See License.txt for details.
The documentation for FAKE is automatically generated using the amazing F# Formatting library.
*.md (Markdown with embedded code snippets) and
*.fsx files (F# script file with embedded Markdown documentation) into a nice HTML documentation.
The code for all the documents can be found in the
helpdirectory on GitHub. If you find a bug or add a new feature, make sure you document it!
If you want to build the documentation, simply run the build script (GitHub link) which builds the documentation.
Fork the FAKE repo on GitHub.
- Clone your personal fork locally.
Add a new git remote in order to retrieve upstream changes.
git remote add upstream https://github.com/fsharp/FAKE.git
Windows users can install Visual Studio 2017 (the Community Edition is freely available for open-source projects).
Linux and Mac users can read "Guide - Cross-Platform Development with F#" to find out the required tools.
For example on windows run
choco install fake -pre
On unix we don't have fake properly packaged jet (please HELP!). You can use the steps outlined in
Note: The vagrant file might be outdated at this time, please help updating it and removing this banner.
Run the build via
fake run build.fsxin order to check if everything works.
Create a new feature branch.
git checkout -b myfeature
- Implement your bugfix/feature.
- Add a bit of documentation (see above).
- Run the build script again, to confirm that all tests pass.
- Commit and push to your fork.
Use GitHub's UI to create a pull request. Write "WIP" into the pull request description if it's not completely ready
If you need to rebase you can do:
1: 2: 3:
git fetch upstream git rebase upstream/master git push origin myfeature -f
- The pull request will be updated automatically.
- Fake 4 (FakeLib) is basically in maintainance mode. Therefore new features need to be at least available as new FAKE 5 module (that might mean that the old module needs to be migrated as part of the PR).
Fake 4 still allows hotfixes, please send the PR against the https://github.com/fsharp/FAKE/tree/hotfix_fake4
It would be helpful if a second PR against master is sent which merges the hotfix into master and adds the hotfix to the FAKE 5 code as well.
Visual Studio users can also install the CodeMaid extension.
Read the F# component design guidelines.
- Read the API-Design-Guidelines below.
We learned from our mistakes, so we use the following guidelines:
- AutoOpen is no longer used
We assume the caller is not opening the module but only the global namespaces
Fake.IO, ... and make sure the code looks nice and structured on the caller side.
For compatibility reasons (migration from legacy). We assume the user doesn't open the global
-> This means we don't add anything in there in the new API.
- Old APIs are marked as Obsolete with a link (hint) to the new API location.
Operators are opened seperatly with a separate
We avoid the
Helperssuffix (because we now expect users to write
As mentioned in the "Fake 5 learn more" section we have a large list to choose from to help the project. One of these things is porting modules to FAKE 5. To save you from some pitfalls this sections guides you in migrating modules with an (at least for me) working approach.
Tooling in netcore it not optimal jet so some things have to be done by hand, but with these steps you have pretty good IDE support:
- Copy one of the existing netcore projects and edit the project file by hand (rename)
- Copy the old implementation files from
/src/app/Fake.<ModuleType>.<Name>(update project file again if required)
- Reference the new files in FakeLib (again updating
FakeLib.fsprojby hand to properly reference the stuff)
Fake.slnand go from there. Because in F# you can only reference stuff defines in files ABOVE, this is ALMOST perfect
- Once stuff compiles in the (
Fake.sln) solution the remaining changes to make the netcore project compile are usually straightforward (you basically only need to fix project references or add framework nuget packages if needed). Let us know if you struggle at this point (in the PR or a new issue).
- Add the info about the new module to the
build.fsx. From this point on the build script will let you know if anything is missing. Again, if you have problems let us know.
- Mark the old module with the
src/Fake-netcore.slnis currently not used (as IDEs don't support that jet). However it is used so speed up the build,
fake run build.fsxwill let you know what to do in the error message.
These steps will ensure: - People using the NuGet package will get the warnings to update the new API - The new API is part of FakeLib (deprecated) - The new API is available as separate module
