Using Design Script w/ ICS Rendition Service for Character Substitution

Question

Hi, 
 I was trying to play around of the printing method in case the ICS server is down. 
 When I do create rendition, the following code for printing file name works. 
 if (characters eq "$FILE$") then envr_var = "RENDSVC_VAULTPATHNAME" characters = envr_value envr_var = "RENDSVC_DOCFILENAME" characters = characters + "\" + envr_value endif 
 The file consists this code was in Projectwise. 
 I exported it, and instead of using create rendition, I used "File">>"Print">>"Design Script" 
 Neither characters or envr_value printed. 
 
 I assume that these codes only work for ICS server and to make this work is using Create Rendition Server. 
 
 How do achieve the same result with a code allows me to print locally? 
 I tried the code below, but result was bit different. 
 if (characters eq "$FILE$") then characters = ip_design 
 
 So my question is how would I print out same value as the code for ICS server. 
 Any suggestion or hint is appreicaited 
 Regards, 
 KZ

OK, I lied. There is a way a strip down the full path to match what rendition services does. For some reason this issue got me really curious so I did a bit of dive into the whole issue. 
 I'm gonna tell you flat out that this is pretty crazy and probably hard to follow. Design scripts have a simple regex parser built in. You can use this to extract pieces of data from strings. Anything matching the regex is assigned to the environment variable. 
 I couldn't figure out how to do a regex that just excluded the beginning of the URL so had to repeatedly strip off characters from the front and save the result. 
 Here's a commented code where I try to explain it: 
 if (characters == '$FILE$') then
	; Renditon Services File Path
	envr_variable = 'RENDSVC_FULLFILEPATHNAME'
	if (envr_value == '') then
 ; Not in rendition services
 ; Set the type of ProjectWise URL we want
 PW_FILE_URL_TYPE = PW_LOCATION_VISUAL
 ; Create a new environment variable to hold the path
 extract_envr_variable = "PWPATH"
 ; only match the Documents and everything after. This removes the pw:\server:datasource\
 extract_envr_expression = "Documents.*"
 ; extract from the projectwise URL
 extract_envr_value = PW_MASTER_FILE_URL
 ; assign the string we just extracted from the URL to characters
 envr_variable = "PWPATH"
 characters = envr_value
 ; Extract everything after the first \ (need to escape \ so 2 \). This eliminates Documents at beginning.
 ; but there is still a \ at the beginning of the string.
 extract_envr_expression = "\.*"
 ; extract from the characters we set above
 extract_envr_value = characters
 ; save new result back into characters
 characters = envr_value
 ; skip any \ at the beginning of the string
 extract_envr_expression = "[^\].*"
 ; extract form the characters we saved above
 extract_envr_value = characters
 ; put the final result back in characters
 characters = envr_value
	else
 ; we are in Renditions
 characters = envr_value
	endif
endif
