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 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 0.4.1 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 EOF
