# File was first taken from the following location:
#
#   http://www.tomaw.net/configs/zshrc
#
# Some additions were made by me, Jonathan Patrick Davies <jpds@ubuntu.com>.
# Among these are the Launchpad, Debian, Wikipedia/Wikitravel, BBC search,
# Demonoid, Lonely Planet, Urbandictionary and other various functions. I also
# implemented a few "if" statements to stop zsh complaining about any missing
# objects and placed the dircolors support.
#
# The forkex() function is thanks to Siegfried-Angel Gevatter Pujals
#   <rainct@ubuntu.com>.
#
# Some of this file is thanks to <slarti@gentoo.org>, some is take from
# spider's <spider@gentoo.org> zshrc, and some from the zshwiki.org.
# Some bash functions are nicked from ciaranm's <ciaranm@gentoo.org>
# bashrc.

# Very powerful version of mv implemented in zsh. The main feature I

# time by being able to use patterns which are expanded into positional
# parameters. So:
#
# slarti@pohl % zmv (*)foo ${1}bar
#
# On a series of files like onefoo, twofoo, threefoo, fivefoo would be
# renamed to onebar twobar threebar fourbar.
#
# Although that's nifty enough, I suspect there are other features I
# don't know about yet...

# run-help on it :)

# Like xargs, but instead of reading lines of arguments from standard input,
# it takes them from the command line. This is possible/useful because,
# especially with recursive glob operators, zsh often can construct a command
# line for a shell function that is longer than can be accepted by an external
# command. This is what's often referred to as the "shitty Linux exec limit" ;)
# The limitation is on the number of characters or arguments.
#
# slarti@pohl % echo {1..30000}

# zsh: exit 127   /bin/echo {1..30000}

# zed is a tiny command-line editor in pure ZSH; no other shell could do

# fned <funcname>. This is useful for me when I'm using and defining
# functions interactively, for example, when I'm working through the
# Portage tree in CVS. It allows me to edit a function on the fly,
# without having to call the last definition back up from the history
# and re-edit that in ZLE. It also indents the function, even if it was
# defined on all one line in the line editor, making it easy as anything

# in the history for the first line beginning with what you have typed so
# far.  After predict-off, editing returns to normal for the line found.
# In fact, you often don't even need to use predict-off, because if the
# line doesn't match something in the history, adding a key performs
# standard completion - though editing in the middle is liable to delete

# run-help is a help finder, bound in ZLE to M-h.  It doesn't need to be
# autoloaded to work - the non-autoloaded version just looks up a man
# page for the command under the cursor, then when that process is
# finished it pulls your old command line back up from the buffer stack.
# However, with the autoloaded function and:
#
# mkdir ~/zsh-help; cd ~/zsh-help MANPAGER="less" man zshbuiltins | \
# colcrt | perl /usr/share/zsh/4.2.1/Util/helpfiles
#
# It'll work for zsh builtins too. By the way, I've assumed some things
# in that command. ~/zsh-help can be wherever you like, MANPAGER needs
# to be any standard pager (less, pg, more, just not the MANPAGER I have
# defined in this file), colcrt can be col -bx, and the path to
# helpfiles may be different for you (Util may not even be installed
# with your distribution; fair enough, make install doesn't install it.
