Setup with a single command line argument

[isawen]

Hi again,

Probably this is how the actual ${GetOption} command works, but I wanted to be sure.
Let's assume my installer parses the command line arguments passed when executed and it searches for this flag option "/argument1".

code:


ClearErrors

${GetOptions} $cmdLineParams '/argument1' $R0

IfErrors +2 0

If I execute the installer and pass the /argument1234 it detects that /argument1 was passed. Is there a way to avoid this situation?

Thanks,
Isa

use GetParameters

I'm not sure what do you mean by ${GetParameter}.
I'm using it to get the command line arguments into my $cmdLineParams variable.

use the /argument=1 then StrCmp $R0 1

That could be a solution but it's more fashion way to have a simple flag (without any value). If this is not possible then I will consider using this.

Thanks,
Isa

My flag name is argument1, but that doesn't mean I'm parsing the last 1 from the argument.
Maybe I have choosed a bad name for the argument.

My point is that if you want to have just a flag to be passed as the argument, when you pass as argument a string that begins with your flag the NSIS will consider the flag present it's like the argument you are passing is somehow truncated.

If you want to match /argument1 exactly then you'll have to also check $R0 is an empty string.

Indeed, how come this didn't cross my tired mind.
Again thanks for your help.
