Re: Perl6: too bad non-greediness is not made the default
in thread Parsing with Perl 6
I beg to differ.
My general principle is to be lax on what I receive and
strict on what I emit.
So I try to write my regexen as lax as possible and to
"synchronize" my match on characters/sequences I am sure
will be present
in the input. This means that I often use .*?
in my regexen. Using the greedy counterpart will lead to
a lot of backtracking and more so geometrically with the
number of .*?.
Also I incrementally build my regexen
testing them on samples: non greedy match also is
less a nuisance here when examining the matches.
Regexen are a tricky art and I like to
abuse it at (*) the risk of being called demented.
(*) And I beg to disagree with Felix Gallo, France is the
lang of semiology, not of semiotics...
and hair splitting too, BTW. And, on a related field,
tagmemics foray in France is collateral to the introduction of american
camelides but has yet to appear widely in French.
tagmemique is indeed French neologism that googlewhacks until the present node
