(Lisp but with indentations.) An interpreter for Calcit snapshot file.
This project provides a runner for compact.cirru, written in Rust for low overhead.
APIs implemented in Calcit Runner is mostly learning from Clojure. Major difference arguments order of list functions.
For Ubuntu 20.04 users, binaries are available from http://bin.calcit-lang.org/linux/ . It was mainly provided for CI usages.
For other platforms, I'm afraid you have to build from source in Rust with cargo install --path=./.
Running Calcit Editor with compact=true caclcit-editor enables compact mode,
which writes compact.cirru and .compact-inc.cirru instead of Clojure(Script).
A compact.cirru file may look like:
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! ()
But, you probably don't like it. You only to edit code with a simple text editor. So.... there's also command for bundling compact.cirru from separated files:
bash
package.cirru
src/
app.main.cirru
app.lib.cirru
package.cirru should contain fields:
cirru
{}
:package |app
:modules $ []
:init-fn |app.main/main!
:reload-fn |app.main/reload!
:version |0.0.1
and files in src/ are source files of namespace form and definitions. By running:
bash
bundle_calcit --src ./src --out ./compact.cirru
a bundled compact.cirru file will be created.
Run:
```bash cr run calcit/compact.cirru
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
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.cirru
cr compact.cirru --emit-js --mjs # TODO compile to mjs ```
Configurations inside calcit.cirru and compact.cirru:
cirru
:configs $ {}
:modules $ [] |memof/compact.cirru |lilac/
Paths defined in :modules field are just loaded as files from ~/.config/calcit/modules/,
i.e. ~/.config/calcit/modules/memof/compact.cirru.
Modules that ends with /s are automatically suffixed compact.cirru since it's the default filename.
To load modules in CI environments, make use of git clone.
I use these commands to run local examples:
```bash cargo run --bin cr calcit/snapshots/test.cirru # a bunch of local tests
cargo run --bin cr calcit/snapshots/test.cirru --emit-js
cargo run --bin cr -- -e 'range 100'
cargo run --bin cr calcit/compact.cirru # this example combined with calcit-editor ```
compact.cirru file parsing.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.
