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 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
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.
