Purerl: Erlang back end for the PureScript compiler
Purerl is a backend for the PureScript compiler that targets Erlang source code. It allows developers to generate Erlang files from PureScript code, facilitating the use of PureScript in Erlang environments. The project includes various resources such as documentation, installation guides, and examples for users.
- ▪Purerl is designed to work with the mainline PureScript compiler to generate .erl source files.
- ▪Binaries for purerl can be downloaded from GitHub releases, and a nix overlay is available.
- ▪The recommended usage involves configuring spago to use the purerl backend for building and running projects.
