Is it possible to pass parameters to a script being run as a text filter?
I have a perl script that I use to adjust html code that has a number of
instances like this:
"top: 753px; left: 27px;"
"top: 1928px; left: 776px;"
and add a specified amount to each "top" and "left" value by executing code
in my replacement regex:
s/top: (\d+)px; left: (\d+)px;/top: @{[ $1+300 ]}px; left: @{[ $2+50 ]}px/g;
to end up with:
"top: 1053px; left: 77px;"
"top: 2228px; left: 826px;"
Currently the addition amounts are hard-coded in the script. Is there a way
to pass them as variables when executing the text filter? I could do it by
putting something at the start of the text I'm running the filter on and
then parsing that at the beginning of my script, but I'd rather not do
that. Wondering if it's possible to actually pass variables to a text
filter script, similar to the way you can when running the script in the
terminal:
perl myscript.pl 300 50
and then in my script I could have:
s/top: (\d+)px; left: (\d+)px;/top: @{[ $1+$ARGV[0] ]}px; left: @{[
$2+$ARGV[1] ]}px/g;
Thanks for any help/ideas,
-matt
