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_ALWAYS_LOAD_ALL**
-Enables the whole Grml setup for root, if set to a non zero value.
+: **GRML_COMP_CACHING**
+If set to //yes// (the default), the setup will enable zsh's completion caching
+mechanism, with the caching data being placed into //$GRML_COMP_CACHE_DIR//.
+
+: **GRML_COMP_CACHE_DIR**
+This defines where zsh's completion caching data will be placed, if
+//$GRML_COMP_CACHING// is active. The default is //${ZDOTDIR:-$HOME}/.cache//.
+The setup will ensure the directory exists before attempting to use it.
+
+: **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".
+: **GRML_NO_APT_ALIASES**
+A non-empty value inhibits the definition of apt-specific short aliases,
+such as ag, agi, ati etc.
+
+: **GRML_NO_SMALL_ALIASES**
+A non-empty value inhibits the definition of 2-letter aliases such as da.
+ls, ll, la and other common ls-related aliases are exempt from this, as are
+the aliases inhibited by GRML_NO_APT_ALIASES.
+
: **GRMLSMALL_SPECIFIC**
Set this to zero to remove items in zsh config, which do not work in
grml-small.
: **NOCOR**
Non zero values deactivate automatic correction of commands.
+: **NOETCHOSTS**
+Non zero values deactivate parsing of "/etc/hosts" disabling host completion
+using file's contents.
+
: **NOMENU**
If set to zero (default), allows selection from a menu, if there are at least
five possible options of completion.
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.
+
+
+= GRML-ZSHRC SPECIFIC STYLES =
+
+Styles are a context sensitive configuration mechanism included with zsh. The
+shell uses it extensively in sub-systems like the completion and the VCS info
+system. It lives outside of the classic shell variable namespace, so it avoids
+polluting it. New functionality in grml's zshrc will likely use styles instead
+of variables. Some features of the setup (like the directory stack handling)
+already use styles. Those styles are documented with the specific features.
+This section documents more general styles.
+
+== Context: :grml:completion:compinit ==
+This context revolves around the zshrc's //compinit// function call, that
+initialises zsh's function based completion system.
+
+: **arguments**
+This style allows the injection of arguments to the command line that is used
+to run compinit. It is a list style and its default is the empty list. Using
+this style, it's possible to add **-i** to //compinit// in order to disable
+//compaudit//.
+\
+```
+zstyle ':grml:completion:compinit' arguments -i
+```
+\
+Only do this, if you know what sort of security checks are disabled if
+//compaudit// is not active and if that's acceptable with your specific setup.
+\
+This style has to be set at the point that Grml's zshrc runs //compinit//. A
+possible way to achieve this is to set it in //~/.zshrc.pre// (see AUXILIARY
+FILES below for details).
+
= FEATURE DESCRIPTION =
This is an in depth description of non-standard features implemented by
zshs inherit the dirstack of the zsh that most recently updated
**DIRSTACKFILE**.
+If you would like to //disable// the persistent dirstack feature altogether,
+you can do that by setting the boolean //enable// style to //false// in the
+right context (the default is //true//):
+\
+```
+zstyle ':grml:chpwd:dirstack' enable false
+```
+
+It is possible to apply a filter to the names of directories that will be
+committed to the persistent dirstack file. There are two ways to configure this
+filter: A general function based filter and a pattern based filter. Both are
+setup via styles in the **':grml:chpwd:dirstack'** context.
+
+To use a function based filter set the //filter// style for that context to the
+name of a function to call every time a directory name is to be added to the
+persistent dirstack. If the function's return value signals success (ie. return
+value "0"), the directory name is filtered out and **not** added to the
+persistent stack. Example:
+\
+```
+function my_dirstack_filter() { [[ $1 == /tmp(|/*) ]] }
+zstyle ':grml:chpwd:dirstack' filter my_dirstack_filter
+```
+
+The pattern based filter uses a list of patterns passed to the //exclude//
+style in the aforementioned context. Each pattern is tested and the first that
+matches will keep the directory name from being added to the persistent stack.
+If none of the patterns matches, the name is added. example:
+\
+```
+zstyle ':grml:chpwd:dirstack' exclude "/tmp(|/*)" "$HOME/tmp(|/*)"
+```
+
+The function based filter is more general, the pattern based filter easier to
+set up. If both filter variants are used at the same time, the function based
+filter will be executed //before// the pattern based one.
+
+If you would like to apply your filters while //loading// the persistent
+dirstack file, set the //filter-on-load// boolean style (the default is
+//false//):
+\
+```
+zstyle ':grml:chpwd:dirstack' filter-on-load true
+```
+
+Setting the //filter-on-load// and //enable// styles needs to be done in
+".zshrc.pre" because the styles need to be set when the main setup is
+executing! The other styles do not have this limitation, but enabling the
+system as well as the initial filtering will obviously be done using settings
+and filters that are configured **at** **that** **point**.
+
+With respect to //filter-on-load//, the rule of thumb is: If you want to filter
+on load, setup everything in ".zshrc.pre" otherwise ".zshrc.local" works just
+as well.
+
+
== DIRECTORY BASED PROFILES ==
-If you want certain settings to be active in certain directories (and
-automatically switch back and forth between them), this is what you want.
+
+If you need to perform certain actions each time you enter certain
+directory-trees, this is the feature you are looking for.
+
+
+=== Initialisation ===
+To initialise the system, you need to call the function `chpwd_profiles' at
+some point in your `zshrc.local'; preferably **after** you configured the
+system. The configuration of the system is described further below.
+
+If you need to do initialisations the first time `chpwd_profiles' is called
+(which should be in your configuration file), you can do that in a function
+called "chpwd_profiles_init". That function needs to be defined **before**
+`chpwd_profiles' is called for this to work.
+
+During the **first** call of `chpwd_profiles' (and therefore all its profile
+functions) the parameter `$CHPWD_PROFILES_INIT' exists and is set to `1'. In
+all other cases, the parameter does not exist at all.
+
+
+=== Styles and Profile-names ===
+To store its configuration, the system uses **functions** and **styles**
+(zsh's context sensitive configuration system), such as this:
+
\
```
zstyle ':chpwd:profiles:/usr/src/grml(|/|/*)' profile grml
zstyle ':chpwd:profiles:/usr/src/debian(|/|/*)' profile debian
```
-When that's done and you enter a directory that matches the pattern
-in the third part of the context, a function called chpwd_profile_grml,
-for example, is called (if it exists).
+When that's done and you enter a directory that matches the pattern in the
+third part of the context, a function called chpwd_profile_grml, for example,
+is called (if it exists).
-If no pattern matches (read: no profile is detected) the profile is
-set to 'default', which means chpwd_profile_default is attempted to
-be called.
+If no pattern matches (read: no profile is detected) the profile is set to
+'default', which means chpwd_profile_default is attempted to be called.
-A word about the context (the ':chpwd:profiles:*' stuff in the zstyle
-command) which is used: The third part in the context is matched against
-**$PWD**. That's why using a pattern such as /foo/bar(|/|/*) makes sense.
-Because that way the profile is detected for all these values of **$PWD**:

+which is used: The third part in the context is matched against ${PWD}. That's
+why using a pattern such as /foo/bar(|/|/*) makes sense. Because that way the
+profile is detected for all these values of ${PWD}:
\
```
-/foo/bar
-/foo/bar/
-/foo/bar/baz
+ /foo/bar
+ /foo/bar/
+ /foo/bar/baz
```
-
-So, if you want to make double damn sure a profile works in /foo/bar
-and everywhere deeper in that tree, just use (|/|/*) and be happy.

-be there.
+'profile' in your functions. You don't need to do anything, it'll just be
+there.
+
+
+=== Controlling Profile Execution ===
-Then there is the parameter **$CHPWD_PROFILE** which is set to the profile,
-that was active up to now. That way you can avoid running code for a
-profile that is already active, by running code such as the following
-at the start of your function:
+During its initialisation run, the system creates a parameter $CHPWD_PROFILE,
+which is set to the profile that was is currently active (the default value is
+"default"). That way you can avoid running code for a profile that is already
+active, by running code such as the following at the start of your function:
\
```
function chpwd_profile_grml() {
[[ ${profile} == ${CHPWD_PROFILE} ]] && return 1
- ...
+ ...
}
```
-The initial value for **$CHPWD_PROFILE** is 'default'.
+If you know you are going to do that all the time for each and every
+directory-profile function you are ever going to write, you may also set the
+`re-execute' style to `false' (which only defaults to `true' for backwards
+compatibility), like this:
+\
+```
+ zstyle ':chpwd:profiles:*' re-execute false
+```
+
=== Signaling availabily/profile changes ===
-If you use this feature and need to know whether it is active in your
-current shell, there are several ways to do that. Here are two simple
-ways:
+If you use this feature and need to know whether it is active in your current
+shell, there are several ways to do that. Here are two simple ways:
-a) If knowing if the profiles feature is active when zsh starts is
- good enough for you, you can put the following snippet into your
- //.zshrc.local//:
-\
-```
-(( ${+functions[chpwd_profiles]} )) &&
- print "directory profiles active"
-```

+enough for you, you can use the following snippet:
+
+(( ${+functions[chpwd_profiles]} )) && print "directory profiles active"
+
+b) If that is not good enough, and you would prefer to be notified whenever a
+profile changes, you can solve that by making sure you start **every**
+profile function you create like this:

-\
-```
function chpwd_profile_myprofilename() {
[[ ${profile} == ${CHPWD_PROFILE} ]] && return 1

...
}
-```
-That makes sure you only get notified if a profile is **changed**,

+That makes sure you only get notified if a profile is **changed**, not
+everytime you change directory. (To avoid this, you may also set the newer
+`re-execute' style like described further above instead of the test on top of
+the function.
+
+
+=== Leaving Profiles ===
+
+When the system switches from one profile to another, it executes a function
+named "chpwd_leave_profile_<PREVIOUS-PROFILE-NAME>()" before calling the
+profile-function for the new profile.
+
=== Version requirement ===
This feature requires zsh //4.3.3// or newer.
== 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 promptinit 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
== PERSISTENT HISTORY ==
If you got commands you consider important enough to be included in every
-shell's history, you can put them into ~/.important_commands and they will be
-available via the usual history lookup widgets.
+shell's history, you can put them into $GRML_IMPORTANT_COMMANDS (which defaults
+for backward compatibility to ~/.important_commands) and they will be available

+=== Customisation ===
+
+To customise keybindings, you can just use zsh's bindkey utility. However, if
+you plan 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.
