StringRegExp() 4th parameter

[phew]

hi!

i have created following regexp:

$parameter = StringRegExp($cmdl[1], '(.*?)' & Chr(34) & '(.*)' & Chr(34) & '(.*?) (-[ns]{0,1})', 1)

so i get an array with 4 values, $parameter[0], $parameter[1], $parameter[2], $parameter[3], ie:

$cmdl[1] = "hellothisis justatest xyz -n"

so:
$parameter[0] = hellothisis
$parameter[1] = justatest
$parameter[2] = xyz
$parameter[3] = -n

but now i want the StringRegExp() also match when the 4th parameter, the -n OR -s is not in the string, so when the 4th parameter is optional:

$cmdl[1] = "hellothisis justatest xyz"

so:
$parameter[0] = hellothisis
$parameter[1] = justatest
$parameter[2] = xyz
$parameter[3] =                <------ empty, " "

how do i do that? the regexp i use (the one above) does only match when -n or -s is specified, but not if i have no -s or -n.

help please!

Try

If ubound($parameter)-1 = 4 then

;do something with 4th parameter

endif

Try

If ubound($parameter)-1 = 4 then

;do something with 4th parameter

endif

doesn't work for me, but thanks for the suggestion. any other ideas?

Are you using this to parse command line parameters?

Are you using this to parse command line parameters?

no its for my irc channel service bot, im using this to parse commands like !mode #chan +mnst -force Edited November 2, 2007 by phew

If none of the commands contain spaces, you could just do:

StringSplit($cmdl[1], " ")

If none of the commands contain spaces, you could just do:

StringSplit($cmdl[1], " ")

this won't work either, because my second parameter can have spaces in it and so this would be split, too

EDIT:

to make it more clear:

i am looking for a way to make a group in a regexp, ie. (.*?) optional. so if there is a group like (.*?) in the string the regexp matches and if there isn't the regexp matches, too. in other programming languages it's often '\' used for that, like \(.*?\) to make the whole group "optional". there must be smtn similiar in au3, too, i'm sure

StringRegExp($cmdl[1], '(.*)\s' & Chr(34) & '(.*)' & Chr(34) & '\s([01])\s(-[ns])?', 1)

is working, i forgot it needs the whitespaces, too
