TCL regexp limitation?

2009-08-28T10:55:41-04:00

I can always use couple of ranges, I mean (512 chars):

Code:

[tomekk@zonk]:/home# echo "puts [regexp {^[a-z]{1,255}[a-z]{0,255}[a-z]{0,2}$} "<512 a chars in here>" ]" | tclsh1

but this limitation is still funny

and besides that, I would wait for nml or someone else who might be knowing about such "issues" - I dont use limiters very often

TCL regexp limitation?

found this on the web:
RE_DUP_MAX, the limit on repetition counts in bounded repetitions, is 255.
not really making sense if it works in php

... BUT, you are free to use
Code:
puts [regexp {^[a-z]{1,}$} abcd]
which works in my case and limits between 1 and unlimited

hehe, I know about that,
but I need to set a range,
otherwise its funny thing with that

without proper regexp I have to use extra [string length]

yeah, I'm using TCL couple of years, but today is a first day when I used the range {1, 256} and I got this what I wrote above ;]

and as far as I know, theres no limitation of regex usage in tcl, havent had any problems at all yet.

//edit:

looks like max specified limit is working with 255 but not with 256 :/

Hey,

Look at this:

Code:

[tomekk@zonk]:/home# php -r 'echo preg_match("/^[a-z]{1,256}$/", "abcd") . "\n";'1

Code:

[tomekk@zonk]:/home# perl -e 'print "abcd" =~ /[a-z]{1,256}/ . "\n"'1

tcl:

Code:

[tomekk@zonk]:/home# echo "puts [regexp {^[a-z]{1,256}$} abcd]" | tclshcouldn't compile regular expression pattern: invalid repetition count(s)

Code:

[tomekk@zonk]:/home# echo "puts [regexp {^[a-z]{1,255}$} abcd]" | tclsh1

Damn, don't tell me that I have to use [string length] instead of one nice regexp?
