Opening a file in a terminal application starts terminal from hardcoded list

[Ferdi265]

 * Nemo version: 4.6.2, also in latest master branch
 * Is issue with desktop or windowed nemo? Only tested windowed, I expect both
 * Distribution: but Arch
 * Graphics hardware *and* driver used: Intel integrated, mesa
 * 32 or 64 bit: 64 bit

Issue

When opening a file with an application that has Terminal=true in its .desktop entry, nemo chooses from a hardcoded list of terminals.

This list of terminals and the code that selects a terminal is in eel/eel-gnome-extensions.c

The actually used list of terminals in in libgio-2.0.so.0, in gio/gdesktopappinfo.c

Steps to reproduce

1. Create a text file
2. Install neovim
3. Right click text file
4. Open With
5. Neovim

Expected behaviour

Neovim is opened in the current default terminal emulator. The same one that is used for "Open in Terminal".

Actual behaviour

A hardcoded list of terminals is used:

• gnome-terminal
• nxterm
• color-xterm
• rxvt
• xterm
• dtterm

if none of these is found, xterm is executed anyway.

I have also experienced this problem, it's incredibly annoying to have to use xterm for this purpose when the entire rest of the system uses another terminal (like termite)

A workaround I use (but that is definitely not a solution) is to symlink nxterm or color-xterm to your preferred terminal.

This of course does not work if you have gnome-terminal installed, but don't want to use it as your primary terminal.

upon further checking (compiled a debug build of nemo), the function with the hardcoded list of applications doesn't even seem to be hit by starting a program. I'll do some further debugging.

EDIT2: I'll recheck this, I might have still had the old version of nemo running at the same time, leading to incorrect results. I'll recheck and reply to this comment with the definite results.

[Ferdi265]

Upon further inspection, the hardcoded list in eel/eel-gnome-extensions.c is not the one used for starting terminal programs via .desktop files.

The actually used list is in libgio-2.0.so.0, in the function prepend_terminal_to_vector, in the file gio/gdesktopappinfo.c

This means that the actual bug here is an upstream GLib bug, and not a bug in nemo.

The bug report - or most relevant one - against glib is here. There is a +1 button on that page. Perhaps Mint users should use it.
