# 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@@.

    # 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).
    #
    # 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}:
    #   /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.
    #
    # The name of the detected profile will be available in a variable called
    # 'profile' in your functions. You don't need to do anything, it'll just
    # be there.
    #
    # Then there is the parameter $CHPWD_PROFILE is set to the profile, that
    # was is currently active. 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'.
    #
    # Version requirement:
    #   This feature requires zsh 4.3.3 or newer.
    #   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"
    #
    #   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
    #       print "chpwd(): Switching to profile: $profile"
    #     ...
    #   }
    #
    #      That makes sure you only get notified if a profile is *changed*,
    #      not everytime you change directory, which would probably piss
    #      you off fairly quickly. :-)
    #
    # There you go. Now have fun with that.

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.

Normally, the root user (EUID == 0) does not get the whole grml setup.
If you want to force the whole setup for that user, too, set
GRML_ALWAYS_LOAD_ALL=1 in .zshrc.pre in root'\''s home directory.

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/
Enjoy your grml system with the zsh!$reset_color"
