# 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.

#
# Obviously, the las two lines are there for demonstration: You need to
# call vcs_info() from your precmd() function (see 'SPECIAL FUNCTIONS' in
# 'man zshmisc'). Once that is done you need a *single* quoted
# '${VCS_INFO_message_0_}' in your prompt.
#
# Now call the 'vcs_info_printsys' utility from the command line:
#
# % vcs_info_printsys
# # list of supported version control backends:
# # disabled systems are prefixed by a hash sign (#)
# git
# hg
# bzr
# darcs
# svk
# mtn
# svn
# cvs
# cdv
# tla
# # flavours (cannot be used in the disable style; they
# # are disabled with their master [git-svn -> git]):
# git-p4
# git-svn
#
# Ten version control backends as you can see. You may not want all
# of these. Because there is no point in running the code to detect
# systems you do not use. ever. So, there is a way to disable some
# backends altogether:
#
# % zstyle ':vcs_info:*' disable bzr cdv darcs mtn svk tla
#
# If you rerun 'vcs_info_printsys' now, you will see the backends listed
# in the 'disable' style marked as diabled by a hash sign. That means the
# detection of these systems is skipped *completely*. No wasted time there.
#
# For more control, read the reference below.
#}}}
#
# CONFIGURATION:
#{{{
# The vcs_info() feature can be configured via zstyle.
#
# First, the context in which we are working:
#       :vcs_info:<vcs-string>:<user-context>
#
# ...where <vcs-string> is one of:
#   - git, git-svn, git-p4, hg, darcs, bzr, cdv, mtn, svn, cvs, svk or tla.
#
# ...and <user-context> is a freely configurable string, assignable by the
# user as the first argument to vcs_info() (see its description below).
#
# There is are three special values for <vcs-string>: The first is named
# 'init', that is in effect as long as there was no decision what vcs
# backend to use. The second is 'preinit; it is used *before* vcs_info()
# is run, when initializing the data exporting variables. The third
# special value is 'formats' and is used by the 'vcs_info_lastmsg' for
# looking up its styles.
#
# There are two pre-defined values for <user-context>:
#   default  - the one used if none is specified
#   command  - used by vcs_info_lastmsg to lookup its styles.
#
# You may *not* use 'print_systems_' as a user-context string, because it
# is used internally.
#
# You can of course use ':vcs_info:*' to match all VCSs in all
# user-contexts at once.
#
# Another special context is 'formats', which is used by the
# vcs_info_lastmsg() utility function (see below).
#
#
# This is a description of all styles, that are looked up:
#   formats             - A list of formats, used when actionformats is not
#                         used (which is most of the time).
#   actionformats       - A list of formats, used if a there is a special
#                         action going on in your current repository;
#                         (like an interactive rebase or a merge conflict)
#   branchformat        - Some backends replace %b in the formats and
#                         actionformats styles above, not only by a branch
#                         name but also by a revision number. This style
#                         let's you modify how that string should look like.
#   nvcsformats         - These "formats" are exported, when we didn't detect
#                         a version control system for the current directory.
#                         This is useful, if you want vcs_info() to completely
#                         take over the generation of your prompt.
#                         You would do something like
#                           PS1='${VCS_INFO_message_0_}'
#                         to accomplish that.
#   max-exports         - Defines the maximum number if VCS_INFO_message_*_
#                         variables vcs_info() will export.
#   enable              - Checked in the 'init' context. If set to false,
#                         vcs_info() will do nothing.
#   disable             - Provide a list of systems, you don't want
#                         the vcs_info() to check for repositories
#                         (checked in the 'init' context, too).
#   disable-patterns    - A list of patterns that are checked against $PWD.
#                         If the pattern matches, vcs_info will be disabled.
#                         Say, ~/.zsh is a directory under version control,
#                         in which you do not want vcs_info to be active, do:
#                         zstyle ':vcs_info:*' disable-patterns "$HOME/.zsh+(|/*)"
#   use-simple          - If there are two different ways of gathering
#                         information, you can select the simpler one
#                         by setting this style to true; the default
#                         is to use the not-that-simple code, which is
#                         potentially a lot slower but might be more
#                         accurate in all possible cases.
#   use-prompt-escapes  - determines if we assume that the assembled
#                         string from vcs_info() includes prompt escapes.
#                         (Used by vcs_info_lastmsg().
#
# The use-simple style is only available for the bzr backend.
#
# The default values for these in all contexts are:
#   formats             " (%s)-[%b|%a]-"
#   actionformats       " (%s)-[%b]-"
#   branchformat        "%b:%r" (for bzr, svn and svk)
#   nvcsformats         ""
#   max-exports         2
#   enable              true
#   disable             (empty list)
#   disable-patterns    (empty list)
#   use-simple          false
#   use-prompt-escapes  true
#
#
# In normal formats and actionformats, the following replacements
# are done:
#   %s  - The vcs in use (git, hg, svn etc.)
#   %b  - Information about the current branch.
#   %a  - An identifier, that describes the action.
#         Only makes sense in actionformats.
#   %R  - base directory of the repository.
#   %r  - repository name
#         If %R is '/foo/bar/repoXY', %r is 'repoXY'.
#   %S  - subdirectory within a repository. if $PWD is
#         '/foo/bar/reposXY/beer/tasty', %S is 'beer/tasty'.
#
#
# In branchformat these replacements are done:
#   %b  - the branch name
#   %r  - the current revision number
#
# Not all vcs backends have to support all replacements.
# nvcsformat does not perform *any* replacements. It is just a string.
#}}}
#
# ODDITIES:
#{{{
# If you want to use the %b (bold off) prompt expansion in 'formats', which
# expands %b itself, use %%b. That will cause the vcs_info() expansion to
# replace %%b with %b. So zsh's prompt expansion mechanism can handle it.
# Similarly, to hand down %b from branchformat, use %%%%b. Sorry for this
# inconvenience, but it cannot be easily avoided. Luckily we do not clash
# with a lot of prompt expansions and this only needs to be done for those.
# See 'man zshmisc' for details about EXPANSION OF PROMPT SEQUENCES.
#}}}
#
# FUNCTION DESCRIPTIONS (public API):
#{{{
#   vcs_info()
#       The main function, that runs all backends and assembles
#       all data into ${VCS_INFO_message_*_}. This is the function
#       you want to call from precmd() if you want to include
#       up-to-date information in your prompt (see VARIABLE
#       DESCRIPTION below).
#
#   vcs_info_printsys()
#       Prints a list of all supported version control systems.
#       Useful to find out possible contexts (and which of them are enabled)
#       or values for the 'disable' style.
#
#   vcs_info_lastmsg()
#       Outputs the last ${VCS_INFO_message_*_} value. Takes into account
#       the value of the use-prompt-escapes style in ':vcs_info:formats'.
#       It also only prints max-exports values.
#
# All functions named VCS_INFO_* are for internal use only.
#}}}
#
# VARIABLE DESCRIPTION:
#{{{
#   ${VCS_INFO_message_N_}    (Note the trailing underscore)
#       Where 'N' is an integer, eg: VCS_INFO_message_0_
#       These variables are the storage for the informational message the
#       last vcs_info() call has assembled. These are strongly connected
#       to the formats, actionformats and nvcsformats styles described
#       above. Those styles are lists. the first member of that list gets
#       expanded into ${VCS_INFO_message_0_}, the second into
#       ${VCS_INFO_message_1_} and the Nth into ${VCS_INFO_message_N-1_}.
#       These parameters are exported into the environment.
#       (See the max-exports style above.)
#}}}
#
# EXAMPLES:
#{{{
#   Don't use vcs_info at all (even though it's in your prompt):
#   % zstyle ':vcs_info:*' enable false
#
#   Disable the backends for bzr and svk:
#   % zstyle ':vcs_info:*' disable bzr svk
#
#   Provide a special formats for git:
#   % zstyle ':vcs_info:git:*' formats       ' GIT, BABY! [%b]'
#   % zstyle ':vcs_info:git:*' actionformats ' GIT ACTION! [%b|%a]'
#
#   Use the quicker bzr backend (if you do, please report if it does
#   the-right-thing[tm] - thanks):
#   % zstyle ':vcs_info:bzr:*' use-simple true
#
#   Display the revision number in yellow for bzr and svn:
#   % zstyle ':vcs_info:(svn|bzr):*' branchformat '%b%{'${fg[yellow]}'%}:%r'
#
# If you want colors, make sure you enclose the color codes in %{...%},
# if you want to use the string provided by vcs_info() in prompts.
#
# Here is how to print the vcs infomation as a command:
#   % alias vcsi='vcs_info command; vcs_info_lastmsg'
#
#   This way, you can even define different formats for output via
#   vcs_info_lastmsg() in the ':vcs_info:command:*' namespace.

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 "
$bg[white]$fg[black]
Please report wishes + bugs to the grml-team: http://grml.org/bugs/
Enjoy your grml system with the zsh!$reset_color"
