Mini Projects

If you’re interested in contributing to Idris, there are several jobs and mini-projects which would help. For example:

Libraries

• Adding libraries and functions to the base package.
• Low level bindings for various C APIs, including, but not limited to:
• Network sockets
• libgcrypt,
• libSDL
• High level, more dependently typed bindings for the above.

Documentation & Examples

• Expand the tutorial with detailed examples and exercises (or even writing a new one)
• Add to the reference documentation.
• Checking for documentation rot in the Idris libraries (see libs/), and Haskell implementation in src.

Internals

• Compiler support for "go to definition" in editors
• Improving the termination and productivity checkers. The current version works in principle, but has a number of issues which need addressing.
• Proof automation, for example:
• A Presburger arithmetic solver (in progress here).
• Commutative ring rewriting (in progress here)

Developer Experience

• Implement something like Interlisp's DWIM for fixing type errors
• Generation of project stubs or "skeleton projects" like those produced by, e.g., stack new. Provide support for generation of project stubs for: new backends, Idris library, Idris binary.
• Flag to generate ignore files for Git and Mercurial.
• Flag to show paths
• Improve Idris docs for algebraic data types.

Bug Squashing

• Investigating and fixing the reports on the issue tracker (low-hanging fruit designates issues that we believe to be easier than others)

Distribution

• Polishing the packaging system
• Packaging for Mac, for ease of installation (ideally not requiring a Haskell platform installed)
• Packaging for Linux distributions

Testing and Benchmarks

• Create Idris versions of toy programs for the benchmark game
• Rewrite the test suite to use HSpec or similar to provide nice error reporting, categorization and modular integration of various testing tools.
