Assuming that you have loaded/sourced version V of package P via a 'package
require' command you can then do

    package ifneeded P V

to query what script Tcl executed to load/source the package. This script
usually contains the path where it was found.

If the package is not in memory yet you can do

    package ifneeded P [package require P]

taking advantage of the fact that 'require' returns the version it loaded.

If you do not know which version is in memory, but know that the package is
loaded you do

    package ifneeded P [package present P]

Ok, that should cover all the bases.

  Hello All
  How could I find out from which file a procedure is loaded (sourced)? We
have a lot of similar scripts with the same name and depending on different
circumstances one is loaded. This works great but when debugging it has
happen some time I'm into the wrong file and do the changes. We are using
the version 8.1 of the interpretator. My intention is to when my application
completes receive a report that proc Blabla where loaded from
\\SERVER1\my\scripts\for\OneState\TheBlablaproc.tcl

  Best regards
  /Jonny
