An interpreter for Calcit snapshot file.
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 Nim for low overhead.
A compact.cirru
file can be:
{} (: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.
Run:
cargo run calcit/compact.cirru
# evaluate
calcit_runner compact.cirru --once # run only once
calcit_runner compact.cirru # watch mode enabled by default
calcit_runner compact.cirru --init-fn='app.main/main!' # specifying init-fn
calcit_runner -e="range 100" # eval from CLI
# emit code
calcit_runner compact.cirru --emit-js # compile to js
calcit_runner compact.cirru --emit-js --emit-path=out/ # compile to js and save in `out/`
calcit_runner compact.cirru --emit-js --mjs # TODO compile to mjs
calcit_runner compact.cirru --emit-ir # TODO compile to intermediate representation
For linux users, download pre-built binaries from http://bin.calcit-lang.org/linux/ .
- Cirru Parser for indentation-based syntax parsing.
- Cirru EDN for
compact.cirru
file parsing.
: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.caclit.nim/compact.cirru
.
To load modules in CI environment, create that folder and clone repos manually.
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.
