Hi,
I am not one of the developers of MC, but I am a long-time (and very
appreciative) user. Please let me make the suggestion to do the following:
Go to the dropdown menus on top of the MC window (xterm or in a text
terminal, either one). Go to the menu which is named "Command" and open
it. Choose the option "Edit extension file" and fire away at it.
Some other details and practical advice:
To open up the dropdown menus, use F9 and the arrow keys to pick the one I
said, then hit Enter. Or click on the inscription "Command" at the top of
the screen or xterm window.
If you want to know where the extension file is, then look in your home
directory for the directory called .mc, and look inside that. You will see
a file called "bindings" and inspection of that file should convince you
that it is the same as what MC is opening with the above-described
sequence. So you can also edit that file by hand and then re-start MC (not
even sure if you need to restart; maybe you don't). You can also do a
backup of that file before messing with it, in case you are afraid of
messing something up. I highly recommend making such a backup. Then you
can be as adventurous as you want to and you do not have to be afraid of
messing up anything at all.
As a small example:
# TeX
regex/\.([Tt][Ee][Xx])$
# Open=%var{EDITOR:vi} %f
Open=m %f
This says what to do with a TEX or tEX or TeX or tex or ...
(anyway, the funny construction is intended to make upper-lower case
irrelevant here)
The original file says that to "open" a TeX file means, open it for
editing and use vi. Well, so I changed that.
The command "m" is short for "menu" which is a home-written script file.
What it does is to create several other script files.
One of the created scripts, called "f" for "file" says to edit the file in
question with JOE, not with vi. It also saves the directory in front of
the filename, so that the file can be opened for editing with the command
"f" no matter where you are in the computer. It also incorporates options
for opening the file to a given line number (valuable if one has a TeX
compile error message) and an option for opening the original file and
another file in a split window.
A second created script file is "l" which means run latex on the file
(which file? that file, the one you loaded up, and again you can be
anywhere in the computer's directory tree and still do this). Moreover,
if the file is plain TeX and not LaTeX then "l" will be clever enough to
understand that and will run tex instead of latex.
So you might not be interested in TeX at all, but the point is that you
can even write your own stuff and tell MC to use it.
You will also notice that on several occasions in the extension file there
is a choice made between whether you are in the terminal or in an xterm.
What app you use to open a file might be dependent upon that, so that
little matter can be taken care of here, invisibly once you have done it.
One last thing:
Sometimes it will probably happen to you that the executable which the
extension file says to use is not present on your system. As an example,
include/image
# Open=if [ "$DISPLAY" = "" ]; then zgv %f; else (gqview %f &); fi
Open=if [ "$DISPLAY" = "" ]; then zgv %f; else (/usr/bin/display
%f &);
# Open=display %f.
View=%view{ascii} identify %f
#View=%view{ascii} asciiview %f
What happened in the above is that I do not have the program called
"gqview" which if I am not mistaken is a GNOME application and I am
running Slackware which has pretty much dropped GNOME several versions
ago. Thus, instead of trying to install the app which would probably also
require me to install numerous libraries, too, I have asked the "display"
program from ImageMagick to be used to open images.
Hope this helps.
