refactor

[jonschlinkert]

In addition to performance improvements, this refactor adds complete Bash 4.3 extglob support (shopt -s extglob), with the possible exception of patterns mentioned in #4.

• expand-brackets refactor

Additional features

• parser is exposed, so that extglob parsers can be used by upstream parsers (like micromatch)
• compiler is exposed, so that extglob compilers can be used by upstream compilers
• source maps

source map example

{ version: 3,
     sources: [ 'extglob' ],
     names: [],
     mappings: 'AAAA,CAAE,CAAE,EAAE,CAAE,CAAC,GAAE,GAAE,EAAC' }
