GetFileName question

so far i was using the GetFileName function to detect the part before a ":" in my $var. i used this function to check protocols of a url (among other things!).

as it might appear that a port and/or a login-name is specified in an url, this function would not work here. i'm looking for a way to put everything left of the first ":" in $var1 to $var2.

any help?

Can you write an example

what i'm checking with GetFileName is

"http://www.google.com" (detects "http")
"md5:s0m3cH3ckSum" (detects "md5")
"ftp://ftp.bla.com" (detects "ftp")

this works well with the GetFileName function. however, as this function works from right/end to the left/beginning, it does not work for these examples:

"http://cerebrum.dnalounge.com:8001/audio/2005/04-29-45945.m3u" (detects "http://cerebrum.dnalounge.com" instead of "http")
"http://anonymous:none@www.google.com" (detects "http://anonymous" instead of "http")

that's why i'm looking for a way to check all text from the left of the first colon.

Name "Output"

OutFile "Output.exe"



!include "WordFunc.nsh"

!insertmacro WordFind



Section

	${WordFind} 'http://cerebrum.dnalounge.com:8001/audio/2005/04-29-45945.m3u' ':' '+1{' $0



	MessageBox MB_OK '$0'

SectionEnd

Or special variant 🙂

Name "Output"

OutFile "Output.exe"



Function ForYathosho

	Exch $0

	Push $1

	Push $2



	StrCpy $1 0

	IntOp $1 $1 + 1

	StrCpy $2 $0 1 $1

	StrCmp $2 '' empty

	StrCmp $2 ':' 0 -3

	StrCpy $0 $0 $1

	goto end



	empty:

	StrCpy $0 ''



	end:

	Pop $2

	Pop $1

	Exch $0

FunctionEnd



Section

	Push 'http://cerebrum.dnalounge.com:8001/audio/2005/04-29-45945.m3u'

	Call ForYathosho

	Pop $0



	MessageBox MB_OK '$0'

SectionEnd

thanks a lot!

i tried the second method, but the same problem appears when i tried "http://cerebrum.dnalounge.com:8001/audio/2005/04-29-45945.m3u"

will try wordfind now, looks very useful, but the function is also quite huge. 😉

That problem appears? ("http://cerebrum.dnalounge.com:8001/audio/2005/04-29-45945.m3u" -> "http")

no, the output is "http://cerebrum.dnalounge.com", it should be "http" though

using wordfind now and it's even better for my purposes, as i can use one function to do multiple operations.. but i have another question!

my old code was

Push $URL

Call GetFileName

Pop $File

i replaced it with

${WordFind} "$URL" "/" "#" $R0

${WordFind} "$URL" "/" "+$R0}" $File

in each case $URL is a link to a file, the function is supposed to get the filname ($File). when i tested this script, i accidently had an url with two slashes at the wrong place ("http://myurl.com/dir//dir/myfile.txt").

my code didn't work then ($File = dir/myfile.txt), so i'm not sure if i made a mistake.

${WordFind} "$URL" "/" "-1}" $File

P.S.
Function ForYathosho output is "http" (Input: "http://cerebrum.dnalounge.com:8001/audio/2005/04-29-45945.m3u") 🙂
