Working with iTerm2

iTerm2 Gotchas

When messing around with locale settings make sure,

• Set locale variables automatically

is set, within the Terminal under the Profiles tab.

If the above setting isn't set within iTerm2 locale settings have been know to get jacked. 🏋️‍♀️

Both iTerm2 and Terminal.app get their locale settings from AppleLocale

The AppleLocale setting can be statused with

defaults read -g AppleLocale

Working with Alacritty

Alacritty does not provide any scrollback support out of the box, a useful work around is to use tmux.

Alacritty does not provide a way to create a new window.

If a connection to a remote server is broken due to network loss, ie. a SSH session is terminated unexpectedly, the hung SSH session can be terminated gracefully with, ⌘ + shift + .

However running the above key sequence could render the terminal unusable due to mouse clicks not properly being sent to the terminal emulator, thus try reseting the terminal

reset

To update Alacritty using cargo

cargo install --git https://github.com/jwilm/alacritty

Alacritty Key Bindings

To setup a meta key binding, ie. alt + [ALPHA_KEY], as far as I can tell, any of the alpha keys on the keyboard can be used, i.e A through z. All that is required is to do something like,

alacritty.yml

key_bindings:
- { key: [ALPHA_KEY],        mods: Alt,     chars: "\x1b[ALPHA_KEY]"                       }

Substitute [ALPHA_KEY] with a key of A through z on the keyboard.

Ex

key_bindings:
- { key: Q,        mods: Alt,     chars: "\x1bq"                       }

The example above adds a keybinding for alt + q

Alacritty Gotchas

If the correct font is not properly set in the alacritty.yml file within the $XDG_CONFIG_HOME Alacritty will fail to launch.

To use a font family with spaces in the name, ie. IBM Plex make sure to quote the name of the font family, ie. "IBM Plex"

To list and search for a particular font on macOS

fc-match -a | grep -i "[mr-fancy-search-string-within-font-family-name]"

The font family name is listed with double quotes when outputted to STDOUT with the above command.
