Other Functions
===============

There are a large number of helpful functions in the Functions/Misc
directory of the zsh distribution.  Most are very simple and do not
require documentation here, but a few are worthy of special mention.

Descriptions
------------

colors
     This function initializes several associative arrays to map color
     names to (and from) the ANSI standard eight-color terminal codes.
     These are used by the prompt theme system (*Note Prompt Themes::).
     You seldom should need to run colors more than once.

     The eight base colors are: black, red, green, yellow, blue,
     magenta, cyan, and white.  Each of these has codes for foreground
     and background.  In addition there are eight intensity attributes:
     bold, faint, standout, underline, blink, reverse, and conceal.
     Finally, there are six codes used to negate attributes: none
     (reset all attributes to the defaults), normal (neither bold nor
     faint), no-standout, no-underline, no-blink, and no-reverse.

     Some terminals do not support all combinations of colors and
     intensities.

     The associative arrays are:

    color
    colour
          Map all the color names to their integer codes, and integer
          codes to the color names.  The eight base names map to the
          foreground color codes, as do names prefixed with `fg-', such
          as `fg-red'.  Names prefixed with `bg-', such as `bg-blue',
          refer to the background codes.  The reverse mapping from code
          to color yields base name for foreground codes and the bg-
          form for backgrounds.

          Although it is a misnomer to call them `colors', these arrays
          also map the other fourteen attributes from names to codes
          and codes to names.

    fg
    fg_bold
    fg_no_bold
          Map the eight basic color names to ANSI terminal escape
          sequences that set the corresponding foreground text
          properties.  The fg sequences change the color without
          changing the eight intensity attributes.

    bg
    bg_bold
    bg_no_bold
          Map the eight basic color names to ANSI terminal escape
          sequences that set the corresponding background properties.
          The bg sequences change the color without changing the eight
          intensity attributes.

     In addition, the scalar parameters reset_color and bold_color are
     set to the ANSI terminal escapes that turn off all attributes and
     turn on bold intensity, respectively.

fned NAME
     Same as zed -f.  This function does not appear in the zsh
     distribution, but can be created by linking zed to the name fned
     in some directory in your fpath.

is-at-least NEEDED [ PRESENT ]
     Perform a greater-than-or-equal-to comparison of two strings
     having the format of a zsh version number; that is, a string of
     numbers and text with segments separated by dots or dashes.  If
     the PRESENT string is not provided, $ZSH_VERSION is used.
     Segments are paired left-to-right in the two strings with leading
     non-number parts ignored.  If one string has fewer segments than
     the other, the missing segments are considered zero.

     This is useful in startup files to set options and other state
     that are not available in all versions of zsh.

          is-at-least 3.1.6-15 && setopt NO_GLOBAL_RCS
          is-at-least 3.1.0 && setopt HIST_REDUCE_BLANKS
          is-at-least 2.6-17 || print "You can't use is-at-least here."

nslookup [ ARG ... ]
     This wrapper function for the nslookup command requires the
     zsh/zpty module (see *Note The zsh/zpty Module::).  It behaves
     exactly like the standard nslookup except that it provides
     customizable prompts (including a right-side prompt) and
     completion of nslookup commands, host names, etc. (if you use the
     function-based completion system).  Completion styles may be set
     with the context prefix `:completion:nslookup'.

     See also the pager, prompt and rprompt styles below.

run-help
     See `Accessing On-Line Help' (*Note Utilities::).

tetris
     Zsh was once accused of not being as complete as Emacs, because it
     lacked a Tetris game.  This function was written to refute this
     vicious slander.

     This function must be used as a ZLE widget:

          autoload -U tetris
          zle -N tetris
          bindkey KEYS tetris

     To start a game, execute the widget by typing the KEYS.  Whatever
     command line you were editing disappears temporarily, and your
     keymap is also temporarily replaced by the Tetris control keys.
     The previous editor state is restored when you quit the game (by
     pressing `q') or when you lose.

     If you quit in the middle of a game, the next invocation of the
     tetris widget will continue where you left off.  If you lost, it
     will start a new game.

zargs [ OPTION ... -- ] [ INPUT ... ] [ -- COMMAND [ ARG ... ] ]
     This function works like GNU xargs, except that instead of reading
     lines of arguments from the standard input, it takes them from the
     command line.  This is useful because zsh, especially with
     recursive glob operators, often can construct a command line for a
     shell function that is longer than can be accepted by an external
     command.

     The OPTION list represents options of the zargs command itself,
     which are the same as those of xargs.  The INPUT list is the
     collection of strings (often file names) that become the arguments
     of the command, analogous to the standard input of xargs.
     Finally, the ARG list consists of those arguments (usually
     options) that are passed to the COMMAND each time it runs.  The
     ARG list precedes the elements from the input list in each run.
     If no COMMAND is provided, then no ARG list may be provided, and
     in that event the default command is `print' with arguments `-r
     --'.

     For example, to get a long ls listing of all plain files in the
     current directory or its subdirectories:

          autoload -U zargs
          zargs -- **/*(.) -- ls -l

     Note that `--' is used both to mark the end of the OPTION list and
     to mark the end of the INPUT list, so it must appear twice
     whenever the INPUT list may be empty.  If there is guaranteed to be
     at least one INPUT and the first INPUT does not begin with a `-',
     then the first `--' may be omitted.

     In the event that the string `--' is or may be an INPUT, the -e
     option may be used to change the end-of-inputs marker.  Note that
     this does _not_ change the end-of-options marker.  For example, to
     use `..' as the marker:

          zargs -e.. -- **/*(.) .. ls -l

     This is a good choice in that example because no plain file can be
     named `..', but the best end-marker depends on the circumstances.

     For details of the other zargs options, see man page xargs(1) or
     run zargs with the --help option.

zcalc [ EXPRESSION ... ]
     A reasonably powerful calculator based on zsh's arithmetic
     evaluation facility.  The syntax is similar to that of formulae in
     most programming languages; see *Note Arithmetic Evaluation:: for
     details.  The mathematical library zsh/mathfunc will be loaded if
     it is available; see *Note The zsh/mathfunc Module::.  The
     mathematical functions correspond to the raw system libraries, so
     trigonometric functions are evaluated using radians, and so on.

     Each line typed is evaluated as an expression.  The prompt shows a
     number, which corresponds to a positional parameter where the
     result of that calculation is stored.  For example, the result of
     the calculation on the line preceded by `4> ' is available as $4.
     Full command line editing, including the history of previous
     calculations, is available; the history is saved in the file
     ~/.zcalc_history.  To exit, enter a blank line or type `q' on its
     own.

     If arguments are given to zcalc on start up, they are used to
     prime the first few positional parameters.  A visual indication of
     this is given when the calculator starts.

     The constants PI (3.14159...) and E (2.71828...) are provided.
     Parameter assignment is possible, but note that all parameters
     will be put into the global namespace.

     An extra facility is provided for changing the default output
     base.  Use, for example, `[#16]' to display hexadecimal output
     preceded by an indication of the base, or `[##16]' just to display
     the raw number in the given base.  Bases themselves are always
     specified in decimal.  `[#]' restores the normal output format.

     The output base can be initialised by passing the option `-#BASE',
     for example `zcalc -#16' (the `#' may have to be quoted, depending
     on the globbing options set).

     The prompt is configurable via the parameter ZCALCPROMPT, which
     undergoes standard prompt expansion.  The index of the current
     entry is stored locally in the first element of the array psvar,
     which can be referred to in ZCALCPROMPT as `%1v'.  The default
     prompt is `%1v> '.

     See the comments in the function for a few extra tips.

zed [ -f ] NAME
zed -b
     This function uses the ZLE editor to edit a file or function.

     Only one NAME argument is allowed.  If the -f option is given, the
     name is taken to be that of a function; if the function is marked
     for autoloading, zed searches for it in the fpath and loads it.
     Note that functions edited this way are installed into the current
     shell, but _not_ written back to the autoload file.

     Without -f, NAME is the path name of the file to edit, which need
     not exist; it is created on write, if necessary.

     While editing, the function sets the main keymap to zed and the vi
     command keymap to zed-vicmd.  These will be copied from the
     existing main and vicmd keymaps if they do not exist the first
     time zed is run.  They can be used to provide special key bindings
     used only in zed.

     If it creates the keymap, zed rebinds the return key to insert a
     line break and `^X^W' to accept the edit in the zed keymap, and
     binds `ZZ' to accept the edit in the zed-vicmd keymap.

     The bindings alone can be installed by running `zed -b'.  This is
     suitable for putting into a startup file.  Note that, if rerun,
     this will overwrite the existing zed and zed-vicmd keymaps.

     Completion is available, and styles may be set with the context
     prefix `:completion:zed'.

     A zle widget zed-set-file-name is available.  This can be called by
     name from within zed using `\ex zed-set-file-name' (note, however,
     that because of zed's rebindings you will have to type ^j at the
     end instead of the return key), or can be bound to a key in either
     of the zed or zed-vicmd keymaps after `zed -b' has been run.  When
     the widget is called, it prompts for a new name for the file being
     edited.  When zed exits the file will be written under that name
     and the original file will be left alone.  The widget has no
     effect with `zed -f'.

     While zed-set-file-name is running, zed uses the keymap
     zed-normal-keymap, which is linked from the main keymap in effect
     at the time zed initialised its bindings.  (This is to make the
     return key operate normally.)  The result is that if the main
     keymap has been changed, the widget won't notice.  This is not a
     concern for most users.

zcp [ -finqQvwW ] SRCPAT DEST
zln [ -finqQsvwW ] SRCPAT DEST
     Same as zmv -C and zmv -L, respectively.  These functions do not
     appear in the zsh distribution, but can be created by linking zmv
     to the names zcp and zln in some directory in your fpath.

zkbd
     See `Keyboard Definition' (*Note Utilities::).

zmv [ -finqQsvwW ] [ -C | -L | -M | -p PROGRAM ] [ -o OPTSTRING ] SRCPAT DEST
     Move (usually, rename) files matching the pattern SRCPAT to
     corresponding files having names of the form given by DEST, where
     SRCPAT contains parentheses surrounding patterns which will be
     replaced in turn by $1, $2, ... in DEST.  For example,

          zmv '(*).lis' '$1.txt'

     renames `foo.lis' to `foo.txt', `my.old.stuff.lis' to
     `my.old.stuff.txt', and so on.

     The pattern is always treated as an EXTENDED_GLOB pattern.  Any
     file whose name is not changed by the substitution is simply
     ignored.  Any error (a substitution resulted in an empty string,
     two substitutions gave the same result, the destination was an
     existing regular file and -f was not given) causes the entire
     function to abort without doing anything.

     Options:

    -f
          Force overwriting of destination files.  Not currently passed
          down to the mv/cp/ln command due to vagaries of
          implementations (but you can use -o-f to do that).

    -i
          Interactive: show each line to be executed and ask the user
          whether to execute it.  `Y' or `y' will execute it, anything
          else will skip it.  Note that you just need to type one
          character.

    -n
          No execution: print what would happen, but don't do it.

    -q
          Turn bare glob qualifiers off: now assumed by default, so
          this has no effect.

    -Q
          Force bare glob qualifiers on.  Don't turn this on unless you
          are actually using glob qualifiers in a pattern.

    -s
          Symbolic, passed down to ln; only works with -L.

    -v
          Verbose: print each command as it's being executed.

    -w
          Pick out wildcard parts of the pattern, as described above,
          and implicitly add parentheses for referring to them.

    -W
          Just like -w, with the addition of turning wildcards in the
          replacement pattern into sequential ${1} .. ${N} references.

    -C
    -L
    -M
          Force cp, ln or mv, respectively, regardless of the name of
          the function.

    -p PROGRAM
          Call PROGRAM instead of cp, ln or mv.  Whatever it does, it
          should at least understand the form
               PROGRAM -- OLDNAME NEWNAME
          where OLDNAME and NEWNAME are filenames generated by zmv.

    -o OPTSTRING
          The OPTSTRING is split into words and passed down verbatim to
          the cp, ln or mv command called to perform the work.  It
          should probably begin with a `-'.

     For more complete examples and other implementation details, see
     the zmv source file, usually located in one of the directories
     named in your fpath, or in Functions/Misc/zmv in the zsh
     distribution.

zrecompile
     See `Recompiling Functions' (*Note Utilities::).

zstyle+ CONTEXT STYLE VALUE [ + SUBCONTEXT STYLE VALUE ... ]
     This makes defining styles a bit simpler by using a single `+' as a
     special token that allows you to append a context name to the
     previously used context name.  Like this:

          zstyle+ ':foo:bar' style1 value1 \
                + ':baz'     style2 value2 \
                + ':frob'    style3 value3

     This defines `style1' with `value1' for the context :foo:bar as
     usual, but it also defines `style2' with `value2' for the context
     :foo:bar:baz and `style3' with `value3' for :foo:bar:frob.  Any
     SUBCONTEXT may be the empty string to re-use the first context
     unchanged.

Styles
------

insert-tab
     The zed function _sets_ this style in context `:completion:zed:*'
     to turn off completion when TAB is typed at the beginning of a
     line.  You may override this by setting your own value for this
     context and style.

pager
     The nslookup function looks up this style in the context
     `:nslookup' to determine the program used to display output that
     does not fit on a single screen.

prompt
rprompt
     The nslookup function looks up this style in the context
     `:nslookup' to set the prompt and the right-side prompt,
     respectively.  The usual expansions for the PS1 and RPS1
     parameters may be used (see *Note Prompt Expansion::).
