FSharper

This project is an attempt to build a plug-in to support the F# programming language in ReSharper.

Broadly speaking, its goals are to:

• Provide ReSharper with a PSI (lexer+parser+inference engine)
• Provide integration with existing R# features (e.g., navigation, search, etc.)
• Provide OOP-related as well as FP-related services (e.g., type inferencing helpers)

Status

At the moment, we are working towards the 0.1 release, which aims to have a fully (or maybe 95%) compliant lexer covered with tests. What we need is:

• To correctly define known F# constructs in the .lex. file (and also in Tokens.xml, but see note in the next section).
• To create a sufficient number of lexer tests to ensure everything works.

A correctly working lexer (plus maybe one lexer-based service, e.g., TODO explorer support) would constitute the 0.1 release (tentative roadmap).

Building

In order to compile the project, you need the ReSharper SDK and WiX. If you have both of these on the machine, the project should build out of the box.

Please note that, currently, any changes to Tokens.xml will need to be processed on our end - this is due to one code generation tool not making it into the SDK (please vote for it).

Debugging

• Set Plugin project as StartUp project
• In the Debug section of the project properties
  • Set the start action to "Start external program" and specify the path to your Visual Studio installation e.g. "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe".
  • Set the command line arguments to match your debug output directory e.g. "/ReSharper.Internal /ReSharper.Plugin C:\Code\FSharper\bindebug".
• Press F5 and load a F# project

Contributing

Pull requests are most welcome and will be reviewed and integrated as soon as humanly possible. Right now, the bulk of development happens on the develop branch, though we may make it more GitFlow-correct in the future.
