parser for beginning of a line - Moose-dev

26 Oct 2010

Hi,

I have a case of a language that uses a line based syntax.

Here is an example:
'
label1 => any kind of
text on many lines
label2 => more text on
many
lines
label3 => more text'

This should get 3 key-value pairs.

My current solution goes like this:
key := #newline asParser , ('=>' asParser / #newline asParser) negate star ,
'=>' asParser.
p := (key trimBlanks, key negate star flatten) star.

However, this is quite ugly. One idea to make it simpler would be to have a parser for the
beginning of the line. What do you think?

Cheers,
Doru
