The main difference is the default value of the \`items' style. In
particular, this theme uses _two_ lines instead of one with the plain
\`grml' theme. The rest behaves exactly the same. Here are the defaults
- for \`grml-chroot':
+ for \`grml-large':
- left: rc jobs history shell-level change-root time date newline user
at host path vcs percent
# matter by using zsh's `zstyle' mechanism.

+ Usage: grml_theme_add_token <name> [-f|-i] <token/function> [<pre> <post>]
+
+ <name> is the name for the newly added token. If the \`-f' or \`-i' options
+ are used, <token/function> is the name of the function (see below for
+ details). Otherwise it is the literal token string to be used. <pre> and
+ <post> are optional.
+
+ Options:
+
+ -f <function> Use a function named \`<function>' each time the token
+ is to be expanded.
+
+ -i <function> Use a function named \`<function>' to initialise the
+ value of the token _once_ at runtime.
+
+ The functions are called with one argument: the token's new name. The
+ return value is expected in the \$REPLY parameter. The use of these
+ options is mutually exclusive.
+
+ Example:
+
+ To add a new token \`day' that expands to the current weekday in the
+ current locale in green foreground colour, use this:
+
+ grml_theme_add_token day '%D{%A}' '%F{green}' '%f'
+
+ Another example would be support for \$VIRTUAL_ENV:
+
+ function virtual_env_prompt () {
+ REPLY=\${VIRTUAL_ENV+\${VIRTUAL_ENV:t} }
+ }
+ grml_theme_add_token virtual-env -f virtual_env_prompt
+
+ After that, you will be able to use a changed \`items' style to
+ assemble your prompt.
