[ragel-users] Re: Inline scanner

[Adrian Thurston]

Hey Carlos, I think this does what you want. It moves the processing of
whitespace out of the main machine and should reduce the number of states.

When a whitespace character is seen there is a call to a scanner which
consumes whitespace. When the whitespace scanner sees non-whitespace it
holds it and returns. When it sees the end-of-header pattern ('\n' with
no continuation) it holds the '\n' and returns. This held '\n' is then
read by the end of header string and the header terminates.

Cheers,
 Adrian
