pysimplicityhl 0.3.4

Python module for simplicityhl compiler

pysimplicityhl

a python wrapper for the simplicityhl compiler

Usage

run pysimplicityhl.run_from_python to call the SimplicityHL compiler like this:

import os
import json
import pysimplicityhl

if __name__ == "__main__":
    basedir = os.path.dirname(__file__)
    hl_file = f"'{basedir}/simple.hl'" # contains only a dummy "fn main() {}"
    parameter = [
        "--debug",
        f"{hl_file}",
    ]
    parameter_str = " ".join(parameter) # one single string
    result_json= pysimplicityhl.run_from_python(parameter_str)
    res = json.loads(result_json)
    res["parameter_str"] = parameter_str
    print(json.dumps(res, default=str))

Installation

First build the complete rust project

cargo build

and you should find the binaries in the subfolder target with target folder debug or release.

Now create a python environment ...

python -m venv .venv

... and activate it

. .venv/bin/activate # linux/mac 
. .venv/Scripts/activate # windows (git-bash)

Let poetry add missing libraries with

poetry update

Now build the debug wheel (to be found in folder debug/wheel)

maturin build --manifest-path pysimplicityhl/Cargo.toml

or the release build (to be found in folder relöease/wheel)

maturin build --manifest-path pysimplicityhl/Cargo.toml --release

A quick install (i.e. a forced reinstall) of the newly compiled wheel could look like this, assuming at least one whl file exists.

poetry run pip install --force-reinstall "$(ls -t target/wheels/pysimplicityhl*.whl | head -n 1)"

If you want to do all at once you may test this poe command (make sure the venv is activated)

poetry run poe build-wheel

Test

in the demo folder you will several simplicityHL test files like e.g. the demo file demo/simple.hl which looks like this:

fn main() {}

this example will compile to the binary JA== signifying an empty simplicity program.

Running

poetry run python demo/main.py

and should give the results of several test simplicity files being compiled

Windows users should note the surrounded quotes when stating filenames with full path (see output key parameter_str)
