Note: Version 0.5.0 breaks compatibility with prior versions, the AST has been reworked to allow round trip processing of JavaScript.

Parser for JavaScript

Build Status

Based (loosely) on language-python

Two Versions

There are currently two versions:

How to build

Make sure your locale supports UTF-8. For example, on most Unix-like platforms, you can type:

export LC_ALL=en_US.UTF-8

Library:

cabal clean && cabal configure && cabal build

Tests:

cabal clean && cabal configure -fbuildtests && cabal build

Running the tests

./dist/build/runtests/runtests

To debug the grammar

happy -iparse.txt -g -a  -d src/Language/JavaScript/Parser/Grammar5.y

This generates src/Language/JavaScript/Parser/Grammar5.hs, delete this when done with the debug version

UTF8/Unicode version

Alex 3.0 now supports unicode natively, and has been included as a dependency in the cabal file.

Note: The generation of the lexical analyser has been separated out, to remove the install-time dependency on Alex. If any changes need to be made to the lexer, the Lexer.x source lies in src-dev, and the runalex.sh script will invoke Alex with the appropriate directories.
