How to get the file path of current running skill script

Hi Yi,

If it's at the script level (i.e. not inside a function) you can do get_filename(piport) to get the filename. It is then evaluated at file load time, and so piport is defined to be the file being read.

Andrew.

Hi Andrew

Thank you for your quick feedback.

If I understand you correctly, I need to create a global variable to contain the file path, when the file is loaded.

And then I pass its value to the form when it has been created afterwards.

As the "piport" would point to CIW after file loading and Virtuoso has been started.

And this why you mention "at the script level" in the begin.

Is there any method to get the file name inside a function?

Or simply after loading the file, all the functions are store in the memory, and there is no link to the original file.

Best Regards

Yi

Hi Yi,

There is a way of doing it, but it's not yet documented. I recently filed a CCR requesting this, and it's been planned, but until it's documented I should not really describe it in a public forum.

There is a record of which file functions are defined within, but only when the file was loaded when in debug mode (e.g. with the debugger enabled, or with sstatus(debugMode t) ). So that's not really a viable option either.

The workaround is to define a global variable, as you say.

Hi Yi,

I did create a case and a duplicate CCR for you (you should have received an email from our support system with my reply on the details - please check in case it went into a spam filter - we've had a few occurrences of that recently because of the numbers in the subject line, I think).

Kind Regards,

Andrew.

Alex,

The feature has been there for many, many years, but it's now documented since IC617 ISR7. It's in Chapter 9 "Advanced Topics" of the SKILL Language User Guide in a section headed "Read-time evaluation".

The way you'd use this is as follows:

procedure(printFileThisWasFrom()
  printf( "The file is:%s\n" #.get_filename(piport) )
)

The idea is that #.funcCall(args) is evaluated at the time the file is read - and so you end up with a literal in your code wherever that is placed. If you pp(printFIleThisWasFrom) after loading, you'll see the literal filename string. This is something that you get in other LISP variants too.

Andrew.
