# NAME:
# reporter
#
# SYNOPSIS:
# reporter [all | aliases | bindings | completion | functions |
# limits | options | variables | zstyles]
#
# DESCRIPTION:
# "reporter" prints your current environment variables, shell
# variables, limits, completion settings, and option settings to
# stdout in the form of a script.
#
# If you run into a zsh bug, someone can source the output script to
# recreate most of the environment under which you were working.
#
# IMPORTANT: "source" this script, don't try to run it directly.
# Otherwise it won't report the settings for your
# current shell session.
#
# OPTIONS:
# All command-line options can be abbreviated.
#
# "aliases" prints only aliases.
# "bindings" prints only "bindkey" commands.
# "completion" prints only "compctl" commands.
# "functions" prints "autoload" commands or actual functions.
# "limits" prints "limit" commands for things like cputime, etc.
# "modules" prints "zmodload" commands.
# "options" prints "setopt" commands.
# "variables" prints both shell and environment variables.
# "zstyles" prints "zstyle" commands
#
# "all" tries to find every useful setting under your shell.
# This is the default, and it's the same as typing all
# of the above options on the command line.
#
# CAVEATS:
# Assumes that you have the following programs in your search path:
# awk, cut, echo, grep, sed, sort
# Assumes that your C preprocessor lives in /lib/cpp or /usr/ccs/lib/cpp.
# Uses (and unsets) variables beginning with "reporter_".
# Won't work for versions of zsh that are older than 3.1.3 or so.
#
# RESTRICTIONS:
# DON'T: pretend you wrote it, sell it, or blame me if it breaks.
# DO: as ye will an' ye harm none.
# --Wiccan saying, I think
#
# BUGS:
# I'm sure there are more than a few. To be safe, run "zsh -f" before
# sourcing the output from this script. If you have "screen", you may
# want to use that, too; I hammered my terminal settings beyond repair
# when using an early version, and "screen" saved me from having to
# login on another terminal.
#
# HISTORY:
# The name was ripped off from the Emacs "reporter.el" function.
# The idea came from a mail message to the ZSH mailing list:

# UNAME
#
# This shows your system name. It's extremely system-dependent, so
# we need a way to find out what system you're on. The easiest
# way to do this is by using "uname", but not everyone has that,
# so first we go through the search path.
#
# If we don't find it, then the only thing I can think of is to
# check what's defined in your C compiler, and code in some exceptions
# for the location of "uname" or an equivalent. For example, Pyramid
# has "uname" only in the ATT universe. This code assumes that
# the "-a" switch is valid for "uname".
#
# This section of code sees what is defined by "cpp". It was
# originally written by brandy@tramp.Colorado.EDU (Carl Brandauer).
# Additional error checking and sed hacking added by Ken Phelps.
