Preval

A wannabe compiler tool for JS.

This project is intended to end up as some kind of compiler-esque tool for JS builds.

For the time being, it just replaces constant bindings with its constant value. Not very exciting. Possibly bugged.

Usage

Run all tests and automatically update snapshots:

./p u

Test one specific file:

./p f tests/constants/copy.md

Tests

The test cases are written to a markdown file which is interpreted in a paritcular way.

The test files contain the input and output of the test case, verbatim.

You can create a new test file by starting a line with a comment. The rest of the file is assumed to be the input code. Otherwise the test is assumed to adhere to the structure of existing tests.

State

At the time of writing, the code base is really just a bootstrap, partially taken from Mope and Tenko, with some snapshotting setup for the test cases and some boiler plate for parsing and pre-processing the AST.

The phase 2 code is riddled with old unused stuff from Mope.

Future

This is literally the setup for this project and a proof of concept-y gimmick.
