# USAGE
# If you are using this file as your ~/.zshrc file, please use ~/.zshrc.pre
# and ~/.zshrc.local for your own customisations. The former file is read
# before ~/.zshrc, the latter is read after it. Also, consider reading the
# refcard and the reference manual for this setup, both available from:
#     <http://grml.org/zsh/>

# Contributing:
# If you want to help to improve grml's zsh setup, clone the grml-etc-core
# repository from git.grml.org:
#   git clone git://git.grml.org/grml-etc-core.git
#
# Make your changes, commit them; use 'git format-patch' to create a series
# of patches and send those to the following address via 'git send-email':
#   grml-etc-core@grml.org
#
# Doing so makes sure the right people get your patches for review and
# possibly inclusion.

# zsh-refcard-tag documentation:
#   You may notice strange looking comments in this file.
#   These are there for a purpose. grml's zsh-refcard can now be
#   automatically generated from the contents of the actual configuration
#   file. However, we need a little extra information on which comments
#   and what lines of code to take into account (and for what purpose).
#
# Here is what they mean:
#
# List of tags (comment types) used:
#   #a#     Next line contains an important alias, that should
#           be included in the grml-zsh-refcard.
#           (placement tag: @@INSERT-aliases@@)
#   #f#     Next line contains the beginning of an important function.
#           (placement tag: @@INSERT-functions@@)
#   #v#     Next line contains an important variable.
#           (placement tag: @@INSERT-variables@@)
#   #k#     Next line contains an important keybinding.
#           (placement tag: @@INSERT-keybindings@@)
#   #d#     Hashed directories list generation:
#               start   denotes the start of a list of 'hash -d'
#                       definitions.
#               end     denotes its end.
#           (placement tag: @@INSERT-hasheddirs@@)
#   #A#     Abbreviation expansion list generation:
#               start   denotes the beginning of abbreviations.
#               end     denotes their end.
#           Lines within this section that end in '#d .*' provide
#           extra documentation to be included in the refcard.
#           (placement tag: @@INSERT-abbrev@@)
#   #m#     This tag allows you to manually generate refcard entries
#           for code lines that are hard/impossible to parse.
#               Example:
#                   #m# k ESC-h Call the run-help function
#               That would add a refcard entry in the keybindings table
#               for 'ESC-h' with the given comment.
#           So the syntax is: #m# <section> <argument> <comment>
#   #o#     This tag lets you insert entries to the 'other' hash.
#           Generally, this should not be used. It is there for
#           things that cannot be done easily in another way.
#           (placement tag: @@INSERT-other-foobar@@)
#
#   All of these tags (except for m and o) take two arguments, the first
#   within the tag, the other after the tag:
#
#   #<tag><section># <comment>
#
#   Where <section> is really just a number, which are defined by the
#   @secmap array on top of 'genrefcard.pl'. The reason for numbers
#   instead of names is, that for the reader, the tag should not differ
#   much from a regular comment. For zsh, it is a regular comment indeed.
#   The numbers have got the following meanings:
#         0 -> "default"
#         1 -> "system"
#         2 -> "user"
#         3 -> "debian"
#         4 -> "search"
#         5 -> "shortcuts"
#         6 -> "services"
#
#   So, the following will add an entry to the 'functions' table in the
#   'system' section, with a (hopefully) descriptive comment:
#       #f1# Edit an alias via zle
#       edalias() {
#
#   It will then show up in the @@INSERT-aliases-system@@ replacement tag
#   that can be found in 'grml-zsh-refcard.tex.in'.
#   If the section number is omitted, the 'default' section is assumed.
#   Furthermore, in 'grml-zsh-refcard.tex.in' @@INSERT-aliases@@ is
#   exactly the same as @@INSERT-aliases-default@@. If you want a list of
#   *all* aliases, for example, use @@INSERT-aliases-all@@.

# debian's setup. It ensures the terminal is in the right mode, when zle is

# zsh in use to have the `zsh/terminfo' module built.

# Guidelines for adding key bindings:
#
#   - Do not add hardcoded escape sequences, to enable non standard key
#     combinations such as Ctrl-Meta-Left-Cursor. They are not easily portable.
#
#   - Adding Ctrl characters, such as '^b' is okay; note that '^b' and '^B' are
#     the same key.
#
#   - All keys from the $key[] mapping are obviously okay.
#
#   - Most terminals send "ESC x" when Meta-x is pressed. Thus, sequences like
#     '\ex' are allowed in here as well.

  prompt grml

    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>]%

    The prompt itself integrates with zsh's prompt themes system (as you are
    witnessing right now) and is configurable to a certain degree. In
    particular, these aspects are customisable:

        - The items used in the prompt (e.g. you can remove \`user' from
          the list of activated items, which will cause the user name to
          be omitted from the prompt string).

        - The attributes used with the items are customisable via strings
          used before and after the actual item.

    The available items are: at, battery, change-root, date, grml-chroot,
    history, host, jobs, newline, path, percent, rc, rc-always, sad-smiley,
    shell-level, time, user, vcs

    The actual configuration is done via zsh's \`zstyle' mechanism. The
    context, that is used while looking up styles is:

        ':prompt:grml:<left-or-right>:<subcontext>'

    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.
          (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'
          accordingly. Default (left): rc change-root user at host path vcs
          percent; Default (right): sad-smiley

    Available styles in 'items:<item>' are: pre, post. These are strings that
    are inserted before (pre) and after (post) the item in question. Thus, the
    following would cause the user name to be printed in red instead of the
    default blue:

        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
    is exactly, what is still required with the new \`pre' value).

function prompt_grml-chroot_help () {
    cat <<__EOF0__
  prompt grml-chroot

    This is a variation of the grml prompt, see: prompt -h grml

    The main difference is the default value of the \`items' style. The rest
    behaves exactly the same. Here are the defaults for \`grml-chroot':

        - left: grml-chroot user at host path percent
        - right: (empty list)

function prompt_grml-large_help () {

  prompt grml-large

    This is a variation of the grml prompt, see: prompt -h grml

    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-large':

        - left: rc jobs history shell-level change-root time date newline user
                at host path vcs percent
        - right: sad-smiley

  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.

    There is a utility function \`grml_theme_has_token', which you can use
    to test if a token exists before trying to add it. This can be a guard
    for situations in which a \`grml_theme_add_token' call may happen more
    than once.

  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.

zsh-help - hints for use of zsh on grml
=======================================$reset_color"

    print '
Main configuration of zsh happens in /etc/zsh/zshrc.
That file is part of the package grml-etc-core, if you want to
use them on a non-grml-system just get the tar.gz from
http://deb.grml.org/ or (preferably) get it from the git repository:

  http://git.grml.org/f/grml-etc-core/etc/zsh/zshrc

This version of grml'\''s zsh setup does not use skel/.zshrc anymore.
The file is still there, but it is empty for backwards compatibility.

For your own changes use these two files:
    $HOME/.zshrc.pre
    $HOME/.zshrc.local

The former is sourced very early in our zshrc, the latter is sourced
very lately.

System wide configuration without touching configuration files of grml
can take place in /etc/zsh/zshrc.local.

For information regarding zsh start at http://grml.org/zsh/

Take a look at grml'\''s zsh refcard:
% xpdf =(zcat /usr/share/doc/grml-docs/zsh/grml-zsh-refcard.pdf.gz)

Check out the main zsh refcard:
% '$BROWSER' http://www.bash2zsh.com/zsh_refcard/refcard.pdf

And of course visit the zsh-lovers:
% man zsh-lovers

You can adjust some options through environment variables when
invoking zsh without having to edit configuration files.
Basically meant for bash users who are not used to the power of
the zsh yet. :)

  "NOCOR=1    zsh" => deactivate automatic correction
  "NOMENU=1   zsh" => do not use auto menu completion
                      (note: use ctrl-d for completion instead!)
  "NOPRECMD=1 zsh" => disable the precmd + preexec commands (set GNU screen title)
  "NOTITLE=1  zsh" => disable setting the title of xterms without disabling
                      preexec() and precmd() completely
  "BATTERY=1  zsh" => activate battery status (via acpi) on right side of prompt
  "COMMAND_NOT_FOUND=1 zsh"
                   => Enable a handler if an external command was not found
                      The command called in the handler can be altered by setting
                      the GRML_ZSH_CNF_HANDLER variable, the default is:
                      "/usr/share/command-not-found/command-not-found"

A value greater than 0 is enables a feature; a value equal to zero
disables it. If you like one or the other of these settings, you can
add them to ~/.zshrc.pre to ensure they are set when sourcing grml'\''s
zshrc.'

    print "

Please report wishes + bugs to the grml-team: http://grml.org/bugs/
