I am trying to run a tcl script using wish as
$ wish main.tcl
output of the command is

 Error in startup script: expected integer but got "Sans"
    (database entry for "-font" in widget ".menubar")
    invoked from within
"menu .menubar"
    (procedure "CreateGui" line 11)
    invoked from within
"CreateGui"
    (file "./rshift.vfs/lib/app-shift/shift.tcl" line 215)
    invoked from within
"source ./rshift.vfs/lib/app-shift/shift.tcl"
    ("package ifneeded app-shift 1.0" script)
    invoked from within
"package require app-shift"
    (file "rshift.vfs/main.tcl" line 57)

any way to fix this ?

  • probably, but you're not showing your code. We need to see where you create the .menubar widget. I suspect you forgot some quotes.

  • Follow the menu man page to the -font option to the font man page to the Font Descriptions section. It looks like you intended usage #1 but actually specified #3

after spending hours on it, I found the fix. I just commented *font: xft:DejaVu Sans Mono for Powerline-10:pixelsize=30 in ~/.Xresources and Surprisingly, I am able to use the script without any issue.

may be tk is confused with the extra parameters -10:pixelsize=30 in font name.

hint: use xrdb ~/.Xresources to reload.
