  • distinguis `tclsh mod-1.tm` vs `package require mod`

    From Mark Summerfield@m.n.summerfield@gmail.com to comp.lang.tcl on Sun Dec 21 05:20:46 2025

    I want to create a mod-1.tm file that contains some functions.
    However, I also want to include some tests.

    If I use:

    package require mod

    I don't want any tests run.

    But if I use:

    $ tclsh mod-1.tm

    or

    $ tclsh mod-1.tm arg1 arg2

    I want the tests to be run.

    How can I do this?

    The global argv0 should be different, in the 2 tclsh cases, it should be mod-1.tm while if you are doing the package require mod, in some other file, run as say, tclsh myapp.tcl, then argv0 would be myapp.tcl.

    Thank you and Emiliano for your answers. Both your approaches worked.
    In the end I've decided to use this:

    if {[string match *.tm $::argv0]} {
    # this executes if run directly; otherwise ignored
    }

    I never create my own pkgIndex packages only .tm modules so this is all I need since
    my applications always have a suffix of .tcl or .tk (or no suffix).
