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/Grammar5.y This generates src/Language/JavaScript/Parser/Grammar.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. Changes 0.5.6 Remove constraint on Alex 3.0.1, it is only required to make changes to the lexer. Closes #19 0.5.5 Updated version ranges for GHC 7.6.1, courtesy of @mietek Note: requires alex 3.0.1 for development (not install) 0.5.4 Fixed bug where lexer switches to regexp mode after a ']' char, reported by @aszlig 0.5.3 Merge pull requests from @aszlig to add octal support, and to allow leading zeros in exponents 0.5.2 Merged pull request from @markwright added some missing test files to the cabal file. Added runalex.sh and Lexer.x to the cabal file. 0.5.1 Export CommentAnnotation(..). Simplify AST by getting rid of JSFunctionBody, JSSourceElements, JSStatementBlock, JSStatementList. They are replaced by JSBlock or a simple list. Also fix lexer mode in presence of whitespace. Changed way tests are invoked, to allow Travis integration. 0.5.0 Rework AST to allow full round-trip parsing and output of JavaScript. Breaks AST compatibility with prior versions 0.4.10 Moved Lexer.x into a separate directory, and made a script to call alex to generate Lexer.hs. This means alex is not required at install time 0.4.9 Make alex and happy versions more explicit. Expose the AlexSpan data type, so parse error positions can be reported. 0.4.8 Close issue https://github.com/alanz/language-javascript/issues/5 by correcting the lexical analyser for DecimalLiteral 0.4.7 Continue ECMASCRIPT update, remove incorrect future reserved words for "code", "mode", "of", "one", "or" and "strict", put in by accident/stupidity. 0.4.6 Update to ECMASCRIPT 5.1 by allowing continuations in string literals Include build dependencies on alex >= 3.0 and happy. 0.4.5 Update cabal file and docs for Alex 3.0, giving out of the box unicode support 0.4.4 Allow unicode characters in comments 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 EOF
