The %f macro for mcedit is incorrect

System: Fedora 24

The %f macro in mcedit is not correct. It contains the current file name that is selected in the panel but not the actual file name that is opened in mcedit.

I created the mcedit item to run C++ program:
+= f \.cpp$
r Run

clear
app_path=/tmp/$(uuidgen)
if g++ -o $app_path "%f"; then

$app_path
rm $app_path

fi
echo 'Press any key to exit.'
read -s -n 1

Imagine that I opened the file a.cpp in mcedit.
Then I pressed alt+` and switched to panel.
Then I selected (or even opened in mcedit) the file b.cpp.
Then I pressed alt+` and switched back to mcedit with a.cpp.
Then I executed my item "Run" from user menu.
And... The b.cpp will be compiled and run. This is wrong. Why b.cpp? I executed "Run" from a.cpp.

I propose you to do the new macros for mcedit.

%opened_file

• the file name that is opened in current instance of mcedit.

%opened_file_full_path

• as %opened_file but full path to that file.

I think that %opened_file may be not safe because the current directory may be changed in mc panel. So it is better to use %opened_file_full_path.

%opened_file_dir

• full path to directory where %opened_file is.

%save

• save opened file before executing the menu commands. May be useful in some cases. For example I don't want to press F2 every time before run changed code.

I agree that editor must use the name of opened file not current file in the panel.

The implemented macro parser supports one-symbol names only. Long names like "opened_file_full_path" can't be handled.

[graywolf]

Do for the example:
%n - the file name that is opened in current instance of mcedit.
%o - the full path to file that is opened in current instance of mcedit.
%g - the full path to directory of the file that is opened in current
instance of mcedit.
%v - save opened file before executing the menu item commands.

Or reassign some existed macro for mcedit. Give them the other
appointment. For example %f must be as %n mentioned above because
"name of selected file in the panel" is useless for mcedit.

Let split this ticket to two:

1. Th fix of %f macro in mcedit

Please test
Branch: 3961_mcedit_f_macro
Initial changeset:2b38c3328807e16c2c9fbdc638a0665e8f787f66

2. Add new macros to mcedit.

This can be appended to #3867 or new ticket can be created.

Replying to graywolf:

Do for the example:
%n - the file name that is opened in current instance of mcedit.
%o - the full path to file that is opened in current instance of mcedit.
%g - the full path to directory of the file that is opened in current
instance of mcedit.
%v - save opened file before executing the menu item commands.
