XQLint - XQuery Code Quality Tool.

XQLint parses XQuery files and returns errors and warnings based on semantic analysis. The XQuery parser is generated using REx Parser Generator (http://www.bottlecaps.de/rex/).

Dependencies

• Optionals (to run tests)
  • Walk (https://github.com/coolaj86/node-walk)
  • AMD loader (https://github.com/ajaxorg/node-amd-loader)
  • asyncjs (https://github.com/fjakobs/async.js)

npm install walk amd-loader asyncjs

Generate the parser

The parser can be generated programmatically by using the following XQuery file:

zorba -q generate_xquery_parser.xq -f

Or via http://www.bottlecaps.de/rex/:

REx -ll 2 -backtrack -tree -javascript -a xqlint XQueryParser.ebnf

Running the test suite

Parser test suite

node run_tests.js --keep-going

To parse a particular XQuery file:

node run_tests.js -f filename

For instance:

node run_tests.js -f queries/zorba/boolean/compare0.xq

Unit tests

node tests/all.js

Who is using this project?

ACE, aka the Cloud9 editor (https://github.com/ajaxorg/ace), is using this parser to perform XQuery syntax checking and semantic highlighting of the source code.
