How to change the line spacing in Terminator

configurationgnome-terminatorterminal

To make things more readable, I'd like to put a little more margin between lines of text. I couldn't find an answer with man terminator_config or any of the Preferences panes.

Terminator doesn't support this. In fact, Terminator, such as many other terminal emulators (e.g. gnome-terminal, xfce4-terminal, mate-terminal, roxterm, sakura, tilda...) uses the VTE widget for terminal emulation and the VTE widget does not support this.

You might want to take a look at how fonts are defined, and whether you can take an existing font and create a new one by adding some more space at the top and bottom. I don't know how to do this.

You might also want to take a look at fontconfig, the library responsible for locating the desired font. It might have such a feature, I don't know.

Or you can easily build a modified VTE for yourself, see https://bugzilla.gnome.org/show_bug.cgi?id=738781. Make sure to first find out the exact version of VTE your Terminator is using, which in case of Terminator version <= 1.0 will probably be vte-0.28.2 and start off from that version (or upgrade to Terminator 1.90 and go for vte-0.fourty-whatever).

Update:

VTE implemented this feature in version 0.52. This makes super easy for Terminator (or any other VTE-based terminal emulator) to add support for this. If you still care, please file a feature request against Terminator.

A lot of unix terminals can recognise some (but usually not all) Ansi Escape codes

So you can use those (the ones that work for your terminal) to change the display as needed.

A very simple example (I use printf as it's portable across many different (and old!) shells) :

export _norm_="$(printf '\033[0m')" #reset "everything" to normal
export _bold_="$(printf '\033[1m')"   #set bold
export _rred_="$(printf '\033[0;1;5;31m')" #"reverse red"
echo "This is an ${_rred_}ERROR${_norm_} and this is ${_bold_}A WARNING${_norm_}"

Please not that those may vary depending on the terminal type (TERM=...), and the program you connect to that machine with (most notably: reverse can become "blink" when using some windows terminal such as F-secure instead of Putty, for example..)

In other words: this is not completely portable, and depends on many things. But "bold" is quite always working. "reverse" is more prone to be terminal dependant.

tput is also better to use as it's taking care to find out the proper sequence for your terminal, but it's not always available (not on old machines, for example)
