Hi Guys,
I am using GetNextParm to parse commandline switches.
However, for a value below, the function fails. I would like to know what could be an appropriate fix.
Usage:
setup.exe /S /INSTALLDIR="C:\Program Files\Mydir" /TEMP=c:\temp
Code:
...
Call GetNextParm
Pop $0 ;$0 = /INSTALLDIR="C:\Program
Call GetNextParm
Pop $0 ;$0 = Files\Mydir"
Looks like once a space is encountered, function assumes that it has copied the entire value.
.....................
Function GetNextParm
Exch $0
Push $1
Push $9
Push $8
StrCpy $1 ""
; Trim leading space
TrimLeading:
StrCpy $9 $0 1
StrCmp $9 "" Done
StrCmp $9 '"' DelimitQuote
StrCmp $9 " " "" DelimitSpace
StrCpy $0 $0 "" 1
Goto TrimLeading
; Begin a quote-delimited parameter
DelimitQuote:
StrCpy $0 $0 "" 1
Goto CopyParm
; Begin a space-delimited parameter
DelimitSpace:
StrCpy $9 " "
; Extract the parameter
CopyParm:
StrCpy $8 $0 1
StrCmp $8 "" Done
StrCpy $0 $0 "" 1
StrCmp $8 $9 Done
StrCpy $1 $1$8
Goto CopyParm
Done:
Pop $8
Pop $9
Exch $1
Exch
Exch $0
Exch
FunctionEnd
Bug in GetNextParm?

If you use quotes, GetNextParm expects the _entire_ parameter to be enclosed in quotes.
So if you use this command:
setup.exe /S "/INSTALLDIR=C:\Program Files\Mydir" /TEMP=c:\temp
you will find that GetNextParm will return this
/INSTALLDIR=C:\Program Files\Mydir
So if you use this command:
setup.exe /S "/INSTALLDIR=C:\Program Files\Mydir" /TEMP=c:\temp
you will find that GetNextParm will return this
/INSTALLDIR=C:\Program Files\Mydir
You could trying using the /D switch to set the $INSTDIR instead.

Thanks for the replies.
pengyou: I will try it and get back if this works.
Afrow UK: I ended up using this option but is it true that it only works if used as the last option. If I use it earlier, then the entire command line is treated as the directory for installation. Any thoughts?
