This repo can be installed via cargo
cargo install chialisp
or via pip
pip install chialisp@git+https://github.com/Chia-Network/clvm_tools_rs.git@e17412032aa7d3b8b1d1f931893fb5802eee626a
Note: `pip` installs a subset of the tools installed by `cargo`, including `brun`, `run`, `opc` and `opd`.
The most current version of the language is in the nightly branch:
[nightly](https://github.com/Chia-Network/chialisp/tree/nightly)
To install from a specific branch:
cargo install --no-default-features --git 'https://github.com/Chia-Network/chialisp' --branch nightly
To install a git checkout into your current python environment (must be in some kind of venv or conda environment):
git clone https://github.com/Chia-Network/chialisp
cd chialisp
maturin develop
Install from PYPI:
pip install -i https://pypi.chia.net/nightlies/ chialisp
Most people still compile chialisp via python. One way to set up compilation
in that way is like this:
import json
from chialisp import compile_clvm
def compile_module_with_symbols(include_paths,source):
path_obj = Path(source)
file_path = path_obj.parent
file_stem = path_obj.stem
target_file = file_path / (file_stem + ".clvm.hex")
sym_file = file_path / (file_stem + ".sym")
compile_result = compile_clvm(source, str(target_file.absolute()), include_paths, True)
symbols = compile_result['symbols']
if len(symbols) != 0:
with open(str(sym_file.absolute()),'w') as symfile:
symfile.write(json.dumps(symbols))
The command line tools provided:
- run -- Compiles CLVM code from chialisp
Most commonly, you'll compile chialisp like this:
./target/debug/run -O -i include_dir chialisp.clsp
'run' outputs the code resulting from compiling the program, or an error.
- repl -- Accepts chialisp forms and expressions and produces results
interactively.
Run like:
./target/debug/repl
Example session:
>>> (defmacro assert items
(if (r items)
(list if (f items) (c assert (r items)) (q . (x)))
(f items)
)
)
(q)
>>> (assert 1 1 "hello")
(q . hello)
>>> (assert 1 0 "bye")
failed: CompileErr(Srcloc { file: "*macros*", line: 2, col: 26, until: Some(Until { line: 2, col: 82 }) }, "clvm raise in (8) (())")
>>>

History

This is a second-hand port of chia's [clvm tools](https://github.com/Chia-Network/clvm_tools/) to rust via the work of
ChiaMineJP porting to typescript. This would have been a lot harder to
get to where it is without prior work mapping out the types of various
semi-dynamic things (thanks, ChiaMineJP).
Some reasons for doing this are:
- Chia switched the clvm implementation to rust: [clvm_rs](https://github.com/Chia-Network/clvm_rs), and this code may both pick up speed and track clvm better being in the same language.
- I wrote a new compiler with a simpler, less intricate structure that should be easier to improve and verify in the future in ocaml: [ochialisp](https://github.com/prozacchiwawa/ochialisp).
- Also it's faster even in this unoptimized form.
All acceptance tests i've brought over so far work, and more are being added.
As of now, I'm not aware of anything that shouldn't be authentic when running
these command line tools from clvm_tools in their equivalents in this repository
- opc
- opd
- run
- brun
- repl
argparse was ported to javascript and I believe I have faithfully reproduced it
as it is used in cmds, so command line parsing should work similarly in all three
versions.
The directory structure is expected to be:
src/classic <-- any ported code with heritage pointing back to
the original chia repo.
src/compiler <-- a newer compiler (ochialisp) with a simpler
structure. Select new style compilation by
including a `(include *standard-cl-21*)`
form in your toplevel `mod` form.

Use ```cargo build --no-default-features``` due to differences in how mac m1 and
other platforms handle python extensions.
