Readme for language-javascript-0.4.3

[back to package description]
Parser for JavaScript
---------------------

Based (loosely) on language-python

How to build
------------

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

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


UTF8/Unicode version 

This requires https://github.com/jyp/Alex, in particular the utf8
branch, to generate the Lexer.hs file

$ git clone https://github.com/jyp/Alex.git
$ cd Alex
$ git checkout utf8
$ cabal install

This will put a utf8 enabled alex in ~/.cabal/bin

To switch back to the standard version, 

$ cabal install --reinstall alex

Changes

0.4.3 correct lexer for decimalToken, only leading digit needs to be non-zero.

0.4.2 Expose SrcSpan

0.4.1 Expose AST.Node as well.

0.4.0 Updated JSNode to include location information, and made the parse more true to the original by leaving blocks as such, not replacing with ';'.

0.3.0 ECMA-262 edition 5 compliance.  Required adding JSFunctionExpression and JSPropertyAccessor to the AST.

0.2.2 Heading toward compliance with edition 5. Trailing commas allowed in array literals too.

0.2.1 Allow trailing comma in object literal

0.2.0 ECMAScript 3 allows function expressions to have names, AST.JSFunctionExpression now reflects this

0.1.0 Simplified AST by removing JSElement and JSElementList components

0.0.3 Support for unicode in source. At the moment it only supports
UTF8 encoding, does not recognise byte order marks or UTF-16/UTF-32

0.0.2 Multiline comments were processed in greedy form, now end of
comment recognised properly. Thanks to Tony Morris for reporting this.

0.0.1 Initial release
