#! Grammar for JavaScript. Based on OMeta-JS example from:
|
||||||
|
#! http://jarrett.cs.ucla.edu/ometa-js/#JavaScript_Compiler
|
||||||
|
|
||||||
|
#! The interesting thing about this parser is the mixing of
|
||||||
|
#! a default and non-default tokenizer. The JavaScript tokenizer
|
||||||
|
#! removes all newlines. So when operating on tokens there is no
|
||||||
|
#! need for newline and space skipping in the grammar. But JavaScript
|
||||||
|
#! uses the newline in the 'automatic semicolon insertion' rule.
|
||||||
|
#!
|
||||||
|
#! If a statement ends in a newline, sometimes the semicolon can be
|
||||||
|
#! skipped. So we define an 'nl' rule using the default tokenizer.
|
||||||
|
#! This operates a character at a time. Using this 'nl' in the parser
|
||||||
|
#! allows us to detect newlines when we need to for the semicolon
|
||||||
|
#! insertion rule, but ignore it in all other places.
