parse

Object
-
[callback]
Starts the parsing process; in sync mode this
method blocks until the parsing has finished,
otherwise it should return immediately!
If given a callback, it must be bound to the
end
and error events.
Parameters:

The parse result.
parse_line
(
private
-
line
Lexically analyses a line and parses it accordingly.
Note: When strict parsing is active (default), this method will reject out-of-section lines even if they are syntactically correct (e.g., header definitions outside of a header section).
Parameters:
-
lineString
pause
()
Resumes _parse method after a short timeout; these
small timeouts effectively give the browser more time
to breathe and are a remedy for the 'long running script'
warnings in Firefox.
restrict

skip

over -
[until]
Like
next() but skips lines matching over
until the end of data is reached or, if given,
