A tool for building and testing projects without redoing work unnecessarily.
A very early work in progress!
RBT is short for Roc Build Tool, and can be pronounced "ribbit." 🐸
For now, you'll need to have the nix
package manager installed.
After that, you can either nix-shell
to get into a development shell.
If you want this to happen automatically, one way is to:
direnv
echo "use nix" >> .envrc
direnv allow
At which point, you'll enter a shell whenever you cd
here.
rbt versions roc
and nixpkgs
using niv
.
To update these deps, get into a dev shell and run niv update
, or niv update roc
or niv update nixpkgs
to just update one or the other.
roc_std
To simplify dependency management, rbt vendors a copy of Roc's standard library at vendor/roc_std
.
We keep this in sync with the Roc version from niv, but check in the files to make life easier in CI.
To update this code, get into a dev shell and run sync-roc-std
, then commit the changes.
src/glue.rs
Regenerate bindings between Roc (whose entrypoint is Package-Config.roc
) and src/glue.rs
by running sync-glue
from a dev shell.
If everything compiles and works, then fix any Clippy errors that have shown up in the generated code, probably by putting a #![allow(clippy)]
directive at the top of the file.
