erikd/language-javascript: Parser for JavaScript, in Haskell

原作者: [db:作者] 来自: 网络 收藏 邀请

开源软件名称:

erikd/language-javascript

开源软件地址:

https://github.com/erikd/language-javascript

开源编程语言:

Haskell 69.0%

开源软件介绍:

Parser for JavaScript

Build Status

Based (loosely) on language-python

Two Versions

There are currently two versions:

  • 0.5 series : Is a continuation of the 0.5.X.Y series, from the [master] (https://github.com/erikd/language-javascript/tree/master) branch of this github repository.

  • 0.6 and 0.7 series : This has a vastly different and improved AST which makes if far more difficult to build an non-sensical Javascript AST. This code is in the new-ast branch of this github repository.

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.
