A word that returns the file being loaded

[ruv]

There are standard words source ( -- sd ) and source-id ( -- -1|0|fileid ) that provide some information about the input buffer and the input source.

I would like to have a standard word that returns the full file name of the input source, if the input source is a file and its file name is known.

I'm considering the names:

• source-path ( -- c-addr u )
• source-uri ( -- c-addr u )
  • because in the general case this can be a URI.

Could you please suggest a better name?
