  • gforth startup on Linux GUI oddity

    From Buzz McCool@21:1/5 to All on Wed Jun 1 09:26:00 2022
    I like to have gforth start up and run in a window when I log into my
    Debian Linux PC. I just put the path to gforth in the KDE Plasma GUI
    startup menu and tell it to run in a terminal. Seemed to work fine with
    the old 0.7.3 gforth. I recently changed to the latest gforth and most
    often (but not always) got wacky output like:


    Gforth 0.7.9_20220428

    Backtrace:
    kernel/int.fs:321:10: 0 $7FBDED6A9430 throw
    ok


    Changing the startup call from

    /usr/bin/gforth

    to

    /usr/bin/sleep 5 && /usr/bin/gforth

    seems to resolve the issue, so it looks like the new gforth is too fast,
    or is something else going on?

    The development version uses ANSI escape sequences to show the status
    line at the bottom, while gforth-0.7.3 does not show a status line.

    My guess is that the initialization of the terminal is not complete
    when the status line is printed, leading to some hickup in the ANSI
    escape sequence processing.

    You can test this theory by turning the startup call into

    /usr/bin/gforth -e "' noop is status"

    This turns off the status line. If you still have the same problem,
    the theory is wrong. If the problem is gone, you have an alternative workaround.

    Well I don't have the same problem, I now have a different problem. :-)

    Now gforth doesn't open at all on startup. When I try the above in a
    terminal I get:

    $ gforth -e "' noop is status"

    in file included from *the terminal*:0:-94500100095743:
    *the terminal*:-1:11: error: Undefined word
    ' noop is >>>status<<<

    Sorry, my mistake. It should be

    /usr/bin/gforth -e "' noop is .status"

    Anton -

    Thank you for the above workaround.

    I do like the status bar so I think I'll go back to using:

    /usr/bin/sleep 5 && /usr/bin/gforth

    I appreciate you responding so quickly.
