+ This is the prompt as used by the grml-live system <http://grml.org>. It is
+ a rather simple one-line prompt, that by default looks something like this:
<user>@<host> <current-working-directory>[ <vcs_info-data>]%
used before and after the actual item.
The available items are: rc, rc-always, change-root, user, at, host, path,
- vcs, percent, sad-smiley.
+ vcs, percent, sad-smiley, battery.
The actual configuration is done via zsh's \`zstyle' mechanism. The
context, that is used while looking up styles is:
- ':prompt:grml:<sub-context>'
+ ':prompt:grml:<left-or-right>:<subcontext>'
- Here <sub-context> is either 'items:<item>' or 'setup'. The available
- styles in the \`setup' context are: use-rprompt, items. For example,
- default \`items' style could be configured like this:
-
- zstyle ':prompt:grml:setup' items user at host path \\
- vcs percent
+ Here <left-or-right> is either \`left' or \`right', signifying whether the
+ style should affect the left or the right prompt. <subcontext> is either
+ \`setup' or 'items:<item>', where \`<item>' is one of the available items.
The styles:
- use-rprompt (boolean): If \`true' (the default), print a sad smiley
- in $RPROMPT if the last command a returned non-successful error
- code.
+ in $RPROMPT if the last command a returned non-successful error code.
+ (This in only valid if <left-or-right> is "right"; ignored otherwise)
- items (list): The list of items used in the prompt. If \`vcs' is
present in the list, the theme's code invokes \`vcs_info'
following would cause the user name to be printed in red instead of the
default blue:
- zstyle ':prompt:grml:items:user' pre '%F{red}'
+ zstyle ':prompt:grml:*:items:user' pre '%F{red}'
Note, that the \`post' style may remain at its default value, because its
default value is '%f', which turns the foreground text attribute off (which
