Sets a custom terminal title.
The default terminal title format is %n@%m: %~, which corresponds to
username@host: /path/to/working/directory.
You can set your format using prompt expansion escape sequences. The following example sets the format to show the working directory name:
zstyle ':zim:termtitle' format '%1~'
Apple Terminal does not support the above, but a working directory escape sequence which is sent instead.
By default, the terminal title is updated before each prompt. The used hooks can be customized with the zstyle below. For example, to have the title updated before each prompt and also before a command is executed:
zstyle ':zim:termtitle' hooks 'precmd' 'preexec'
