Quest for a terminal emulator

debian eng pdo sw

The requirements

I need a terminal emulator. This is a checklist of the features that I need:

My experience is that getting all of this to work is not being as easy as it seems, so I'm creating this page to track progress.

gnome-terminal

I've been happily using this for years, and it did everything I needed, until some months ago it started to open new tabs in the terminal's working directory instead of the last tab's working directory. This is a big point of frustration for me.

It also started opening https urls with Firefox, although the preferred browser was Chromium. There seemed to be no way to control it: I looked for firefox or iceweasel in all gconf and dconf settings and found nothing.

The browser issue was fixed by accident when I used Xfce4's settings application to change the browser from Chromium to Firefox and then back to Chromium.

update, thanks to Mathieu Parent, Josh Triplett, Peter De Wachter, Julien Cristau, and Charles Plessy:

It is also possible to restore the "new tab opened inside the same directory of the last tab I was in" behaviour, by enabling "run command as a login shell" so that /etc/profile.d/vte.sh is run (thanks Mathieu Parent for the link).

That in turn spawned extra cleanup work in my .bashrc/.bash_profile/.profile setup, which has been randomly evolving since even before my first Debian "buzz" system. I found that it was setting PROMPT_COMMAND to something else to set the terminal title, conflicting with what vte.sh wants to do.

With regards to loading /etc/profile.d/vte.sh by default, Peter De Watcher sent pointers to relevant bugs: here, here, and here.

An alternative strategy is to work using the prompt rather than PROMPT_COMMAND; an example is in Josh Triplett's .bashrc from git://joshtriplett.org/git/home.

Josh Triplett also said:

To fix the browser launched for URLs, you either need to use a desktop environment following GNOME's mechanism for setting the default browser, or edit ~/.local/share/applications/mimeapps.list and make sure x-scheme-handler/http, x-scheme-handler/https, and x-scheme-handler/ftp are set to your preferred browser's desktop file basename under [Added Associations].

All my issues with gnome-terminal are now gone and I'm only too happy to go back to it.

rxvt-unicode-256color

urxvt took some work. This is where I got with configuration:

URxvt.font: xft:Monospace-10:antialias=true
URxvt.foreground: #aaaaaa
URxvt.background: black
URxvt.scrollBar_right: true
URxvt.cursorBlink: true
URxvt.perl-ext-common: default,matcher,tabbedex
URxvt.url-launcher: /usr/bin/x-www-browser
URxvt.matcher.button: 1
URxvt.perl-lib: /home/enrico/.urxvt/perl
URxvt.color0: black
URxvt.color1: #aa0000
URxvt.color2: #00aa00umask
URxvt.color3: #aa5500
URxvt.color4: #0000aa
URxvt.color5: #aa00aa
URxvt.color6: #00aaaa
URxvt.color7: #aaaaaa
URxvt.color8: #555555
URxvt.color9: #ff5555
URxvt.color10: #55ff55
URxvt.color11: #ffff55
URxvt.color12: #5555ff
URxvt.color13: #ff55ff
URxvt.color14: #55ffff
URxvt.color15: #ffffff

I got all of the tab behaviour that I need by "customizing" the tab script (yuck github :( ).

update: Richard Hartmann pointed out that terminator's upstream maintainer now changed after the old one didn't have time any more, and it should have a release with a ton of improvements anytime soon.

xfce4-terminal

Configuration is in .config/xfce4/terminal, and this is relevant to me:

update: Yves-Alexis Perez points out that to disable the F1 for help in the terminal, you need to remove the accelerator. I tried this and this and didn't have success, but I confess I did not dig too much into it.

Although xfce4-terminal -e does not work as I expect, xfce4-terminal registers a wrapper for x-terminal-emulator that does the right thing with respect to -e (also thanks Yves-Alexis Perez).

Missing

Nothing of my initial requirements seems to be missing, really, so I'm sticking to it for a while to see what happens.

The first itch to scratch is that when the menubar is hidden, the popup menu becomes the entire menubar contents, which does not fit the general use case to have a contextual menu with the most common shortcuts. I'll just declare it useless and get myself used to some new hotkey for starting a new terminal.

update: after fixing my issues with gnome-terminal I've switched back to gnome-terminal: its interface feels less clunky as I'm already used to it.

Other references

Guillem Jover made a similar analysis in 2009, it can be found here.

Thomas Koch mentioned that termit should be able to do all I need, and is scriptable in Lua. I like the sound of that, and it's definitely one I should look next time I find myself shopping for terminal emulators.
