Slow mc and mcedit launch when using X11 forwading

[martins]

Hello,

There was mentions option -X in ticket #2940.
However it is still slow to lauch mcedit by pressing F4 key inside mc, even with alias mcedit='mcedit -X'.

It would be better to control X11 support with an environment variable then with commandline option. This way it would apply on all subprocesses and that variable could be set in login profile script.

regards,
Martin

Any extra variable is pointless.

As described in man page

-X, --no-x11
       Do not use X11 to get the state of modifiers Alt, Ctrl, Shift

This option doesn't influence to any child processes. mc uses it internally to handle key events only. Child processes don't know whether this option on or off.

Do you configure mc to use external editor and your external editor is mcedit?

Thanks for quick reply. Checking option "Use internal editor" resolved the problem.
MC was configured to use external editor, probably by default from Debian installation.

I am still confused why mcedit runs immediately from commandline and not from mc, maybe an alias only applies inside bash, not inside spawn system call.

Yep.

alias is the builtin command of bash.
