 # 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@@.

 # 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.

 #    - grml-chroot
 #
 # They all share the same code and only differ with respect to which items they
 # contain. The main source of documentation is the `prompt_grml_help' function
 # below, which gets called when the user does this: prompt -h grml
 
 function prompt_grml_help () {
     <<__EOF0__
   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
 
         - strip-sensitive-characters (boolean): If the \`prompt_subst' option
           is active in zsh, the shell performs lots of expansions on prompt
           variable strings, including command substitution. So if you don't
           control where some of your prompt strings is coming from, this is
           an exploitable weakness. Grml's zsh setup does not set this option
           and it is off in the shell in zsh-mode by default. If it *is* turned
           on however, this style becomes active, and there are two flavours of
           it: On per default is a global variant in the '*:setup' context. This
           strips characters after the whole prompt string was constructed. There
           is a second variant in the '*:items:<item>', that is off by default.
           It allows fine grained control over which items' data is stripped.
           The characters that are stripped are: \$ and \`.
 
     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 () {
     <<__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

     The main difference is the default value of the \`items' style. In

     \`grml' theme. The rest behaves exactly the same. Here are the defaults
     for \`grml-large':

   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
   "GRML_DISPLAY_BATTERY=1  zsh"
                    => activate battery status on right side of prompt (WIP)
   "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"

 #      Note: limit for recursive symlinks on linux:
 #            http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/fs/namei.c?id=refs/heads/master#l808
 #            This limits recursive symlink follows to 8,
 #            while limiting consecutive symlinks to 40.
 #
 #      When resolving and displaying information about symlinks, no check is made
 #      that the displayed information does make any sense on your OS.
 #      We leave that decission to the user.
 #
 #      The zstat module is used to detect symlink loops. zstat is available since zsh4.
 #      With an older zsh you will need to abort with <C-c> in that case.
 #      When a symlink loop is detected, a warning ist printed and further processing is stopped.
 #
 #      Module zstat is loaded by default in grml zshrc, no extra action needed for that.
 #
 #      Known bugs:
 #      If you happen to come across a symlink that points to a destination on another partition
 #      with the same inode number, that will be marked as symlink loop though it is not.
 #      Two hints for this situation:
 #      I)  Play lottery the same day, as you seem to be rather lucky right now.
 #      II) Send patches.

 Backup a file or folder in place and append the timestamp
 Remove backups of a file or folder, or all backups in the current directory
 
 Usage:
 -h    Display this help text
 -c    Keep the file/folder as is, create a copy backup using cp(1) (default)
 -m    Move the file/folder, using mv(1)
 -r    Remove backups of the specified file or directory, using rm(1). If none
       is provided, remove all backups in the current directory.
 -a    Remove all (even hidden) backups.
 -v    Verbose
 
 The -c, -r and -m options are mutually exclusive. If specified at the same time,
 the last one is used.
 
 The return code is the sum of all cp/mv/rm return codes.
