Execute Regular Expression in Skill

Hello friends,

Here's what I'm trying to accomplish, and where I've hit a roadblock: my skill program writes a .scr script, and then needs to execute the .scr file. The problem is, the .il file resides in C:\Cadence\Setup\, and the .scr file is writtent to whatever the current design directory is. So with a .BRD file open in Allegro, the .scr file is written to the same directory as the BRD file. This causes a problem- the .il skill file can't execute the .scr file. So I'm trying to parse the current design directory with axlCurrentDesign().

Which returns a string of the form: c:/users/poppy/documents/cadence/boardX/allegro/512_238.brd

Now I just need to trim the last part of the string off, everything after the last "/", such that the returned result is:

c:\users\poppy\documents\cadence\boardX\allegro\

Then I can use the above string as the directory file to write the .scr to. I tested by placing the file there manually and it works. So I need to trim the path after the last "/". I'm trying to do with regex, but can't get the pattern right. A patter that in theory works is:

([/]*)$

I can't get it to work for me though. Can anyone help with the pattern entry? Then I will be calling:

rexCompile("\\\$[^/]*\\\$$")

dir= rexReplace(dir, "", 0)

EDIT:

Got it figured out. I guess I was overthinking it. I saw a bunch of threads with many "\\\\" to escape the backslash, so figured I needed that as well. What worked for me was:

rexCompile("[^/]*$")

dir = rexReplace(dir,"", 0)

Check the axlDMFileParts() function.
