ULP and script capabilities question

I'm trying to scope out whether Eagle's scripting or ULP environments

can help with my recently posed question "Library copy and rename device

procedure? (/thread/44708/l/library-copy-and-rename-device-procedure)".

 

So I'd like to know whether and how either of these environments can

create, open, write and close eagle libraries. And I'm likely to need to

use eagle's iterators (aka "loop members"), so this probably needs to

focus on the ULP realm, unless a ULPs can run commands. So...

 

1. I see that the scripting commands include OPEN and WRITE, but I

didn't see a command to create a new library.

OPEN newname.lbr  -->>  opens a new lbr

WRITE;            -->> save the lbr

2. I didn't see any ULP functions that can create, open, write, or close

a library. Did I miss something?

A ULP con only generate a string to return to eagle, or write a SCRIPT

and return the SCRIPT filename (as string) to Eagle.

3. Perhaps ULPs can run commands? But I didn't see any ULP function to

run a command. Again, did I miss something?

string commandstring = "OPEN newname.lbr";

exit(commandstring);

Thanks Alfred, that was very helpful.

So, combined with script command RUN 'ulpname', it seems that:

• a script can call a ULP, which can later return to the running script
• a ULP, can jump to a new script.
• but... a ULP can't call to a script which then returns to the ULP

That makes it a little difficult to use a ULP iterator (member loop) to repeatedly perform a script command. Not sure if that's fatal, but it's interesting.
