Calcit Runner

An interpreter for Calcit snapshot file.

• Home http://calcit-lang.org/
• APIs http://apis.calcit-lang.org/

Running Calcit Editor with compact=true caclcit-editor enables compact mode, which writes compact.cirru and .compact-inc.cirru instead of Clojure(Script). And this project provides a runner for compact.cirru, written on Rust for low overhead.

A compact.cirru file can be:

cirru {} (:package |app) :configs $ {} (:init-fn |app.main/main!) (:reload-fn |app.main/reload!) :modules $ [] :files $ {} |app.main $ {} :ns $ quote ns app.main $ :require :defs $ {} |main! $ quote defn main! () (+ 1 2) |reload! $ quote defn reload! ()

APIs implemented in Calcit Runner is mostly learning from Clojure. Major difference arguments order of list functions.

Usage

Run:

```bash cargo run calcit/compact.cirru

evaluate

cr compact.cirru --once # run only once cr compact.cirru # watch mode enabled by default

cr compact.cirru --init-fn='app.main/main!' # specifying init-fn

cr -e="range 100" # eval from CLI

emit code

cr compact.cirru --emit-js # compile to js cr compact.cirru --emit-js --emit-path=out/ # compile to js and save in out/

cr compact.cirru --emit-ir # compiles intermediate representation into program-ir.json

cr compact.cirru --emit-js --mjs # TODO compile to mjs ```

For linux users, download pre-built binaries from http://bin.calcit-lang.org/linux/ .

Development

• Cirru Parser for indentation-based syntax parsing.
• Cirru EDN for compact.cirru file parsing.

Modules

cirru :configs $ {} :modules $ [] |phlox/compact.cirru

Calcit Runner use ~/.config/calcit/modules/ as modules directory. Paths defined in :modules field are just loaded as files based on this directory, which is: ~/.config/calcit/modules/phlox/compact.cirru.

To load modules in CI environment, create that folder and clone repos manually.

Older version

This interpreter was first implemented in Nim and then switch to Rust. Main change is the order of arguments where operands are now placed at first.
