Some of the behaviour of //grmlzshrc// can be altered by setting certain shell
variables. These may be set temporarily when starting zsh like this:
\
-``` % BATTERY=1 zsh
+``` % GRML_DISPLAY_BATTERY=1 zsh
Or by setting them permanently in **zshrc.pre** (See AUXILIARY FILES below).
: **BATTERY**
-If set to a value greater than zero and //acpi// installed, //grmlzshrc// will
-put the battery status into the right hand side interactive prompt.
+Deprecated. Use **GRML_DISPLAY_BATTERY** instead.
: **COMMAND_NOT_FOUND**
A non zero value activates a handler, which is called when a command can not
be found. The handler is defined by GRML_ZSH_CNF_HANDLER (see below).
+: **GRML_DISPLAY_BATTERY**
+If set to a value greater than zero, //grmlzshrc// will put the battery status
+into the right hand side interactive prompt. Supported OSes are //GNU/Linux//,
+//FreeBSD//, //OpenBSD// and //Darwin//.
+
: **GRML_ZSH_CNF_HANDLER**
This variable contains the handler to be used by COMMAND_NOT_FOUND (see above)
and defaults to "/usr/share/command-not-found/command-not-found".
A non zero value causes shell functions to be profiled. The results can be
obtained with the zprof builtin command (see zshmodules(1) for details).
+: **COMPDUMPFILE**
+Specifies the location of the completion dump file. Default: $HOME/.zcompdump.

= FEATURE DESCRIPTION =
This is an in depth description of non-standard features implemented by
== PROMPT ==
+The //grmlzshrc// now supplies three prompt themes compatible with zsh's
+**promptinit** system. The three themes are called **grml**, **grml-large** and
+**grml-chroot**.
+
+By default, **grml** is used, unless //$GRMLPROMPT// is set to a value larger
+than zero, in which case **grml-large** is used. Lastly, if //$GRML_CHROOT// is
+non-empty, **grml-chroot** is used.
+
+As usual, with promtinit themes, the user may switch to a different theme using
+the //prompt// utility:
+\
+```
+ prompt grml-large
+```
+
+That will use the **grml-large** prompt theme.
+
+The themes are highly customisable. The main source of documentation about
+customisation is the main **grml** theme's doc-string, that is available via
+the following command:
+\
+```
+ prompt -h grml
+```
+
+The other themes also come with doc-strings, but the main theme's is the
+canonical reference about all of them.
+
+This feature requires version //4.3.7// of the shell. Older versions will use
+the classic grml prompt as a fallback.
+
+A note to people who like customisation: If you are **not** using a prompt
+theme for your customisation, but you're either statically setting $PS1 (or
+$PROMPT) or you're constructing one of those variables in zsh's \`precmd()'
+function, make sure you are turning the zsh's prompt theme system **off**
+before doing so. A correct example customisation could look like this:
+\
+```
+ # Turn the prompt system off:
+ prompt off
+ # Customise the prompt yourself:
+ PS1='%~ %# '
+```
+
+You also add your own tokens by using the \`grml_theme_add_token()' function.
+Call the function without arguments for detailed documentation about that
+procedure.
== GNU/SCREEN STATUS SETTING ==
//grmlzshrc// sets screen's hardstatus lines to the currently running command
: **PAGER**
Set less(1) as default pager, if not already set to something different.
-: **SHELL**
-Set explicitly to /bin/zsh, to prevent certain terminal emulators to
-default to /bin/sh or /bin/bash.
-
== OPTIONS ==
Apart from zsh's default options, //grmlzshrc// sets some options
Brings a job, which got suspended with CTRL-z back to foreground.
+=== Customisation ===
+
+To customise keybindings, you can just use zsh's bindkey utility. However, if
+you plan to to use the `//zle-line-init//' or `//zle-line-finish//' hooks
+yourself, make sure you call the following functions in the respective hook:
+
+- **zle-line-init**: //zle-smkx//
+- **zle-line-finish**: //zle-rmkx//
+
+
+This is **required** so the keybindings set up by //grmlzshrc// work. The
+reason for this is to turn the terminal into the right mode while zsh's line
+editor (zle) is running. This enables us to query //terminfo// about escape
+sequences for special keys and thus simplify and generalise our keybinding
+section.
+
+
== SHELL FUNCTIONS ==
//grmlzshrc// comes with a wide array of defined shell functions to ease the
user's life.
screen and ssh.
: **bk()**
-Simple backup of a file or directory using cp(1). The target file name is the
-original name plus a time stamp attached. Symlinks and file attributes like mode,
-ownership and timestamps are preserved.
+Simple backup management of a file or directory using standard unix programs.
+The target file name is the original name plus a time stamp attached. Symlinks
+and file attributes like mode, ownership and timestamps are preserved.
: **cdrecord()**
If the original cdrecord is not installed, issues a warning to the user to
if command is a program.
: **checkhome()**
-Changes directory to $HOME on first invocation of zsh. This is neccessary on
-grml systems with autologin.

Reloads an autoloadable shell function (See autoload in zshbuiltins(1)).
+: **grml_vcs_info_toggle_colour()**
+Toggles between coloured and uncoloured formats in vcs_info configuration.
+This is useful with prompts that break if colour codes are in vcs_info
+format expansions (like the `clint' prompt and every other prompt that
+uses %v to expand the contents of `$vcs_into_msg_0_'). If you are using
+customised vcs_info formats, you shouldn't be using this function, since
+it will set all formats to grml's default values (either coloured or plain)
+again.
