Oh, what the heck, I've got half an hour to waste.

----------
## [[ ${+*} -eq 0 ]] = if variable is set don't set it anymore
[[ ${+USER} -eq 0 ]] && export USER=$USERNAME

You can write this as

(( ${+USER} )) || export USER=$USERNAME

Or even as

export USER=${USER:-$USERNAME}

----------
        ## display user@host and name of current process in (xterm|rxvt) title
        preexec () {print -Pn "\033]0;%n@%m [$1] %~\007"}

It'd probably be better to use ${${(z)1}[1]} there, rather than $1, if
you want just the command name.  Or even ${${${(z)1}:#*[[:punct:]]*}[1]}
in case the first "word" is an open-paren or something.

----------
        function compstyle { }

You meant `function zstyle { }', I'll bet.  It hasn't been called compstyle
for a while now.

----------
alias x='startx & disown && exit'

You can write that as

alias x='startx &! exit'

so that `disown' can't accidentally disown the wrong job.

----------
[in pskill()]

        kill -9 `print -r $pid`

Any reason why that isn't just `kill -9 $pid'?

----------
## invoke this every time when u change .zshrc to
## recompile it.
src()
{
        ! [ -f ~/.zshrc.zwc ] && zcompile ~/.zshrc
        ! [ -f ~/.zcompdump.zwc ] && zcompile ~/.zcompdump
        autoload zrecompile
        [ -f ~/.zshrc ] && zrecompile ~/.zshrc
        [ -f ~/.zcompdump ] && zrecompile ~/.zcompdump
        [ -f ~/.zshrc.zwc.old ] && rm -f ~/.zshrc.zwc.old
        [ -f ~/.zcompdump.zwc.old ] && rm -f ~/.zcompdump.zwc.old
        source ~/.zshrc
}

You should be able to get rid of those first two zcompile lines; just
change the two zrecompile lines to be:

	[ -f ~/.zshrc ] && zrecompile -p ~/.zshrc
        [ -f ~/.zcompdump ] && zrecompile -p ~/.zcompdump

----------
## restore all .bak files
## call this with something like: restore_bak 'find . -name "*.bak"'
restore_bak ()
{
        foreach f ($argv);
        mv $f ${f%%.bak};
        end
}

No problem with that (portability back to 3.0, etc.), but in 4.0:

autoload -U zmv
zmv '(**/)(*).bak' '$1$2'

----------
[in readme()]

In 4.0 with extendedglob you can write that files assignment as

	files=(./(#i)*(read*me|lue*m(in|)ut)*(ND))

That's all.

I think he pinched that (and a few other things) from an old version
of my .zshrc.  Recent copies appear at

  http://adamspiers.org/computing/zsh/files/.zshrc

and are gradually decreasing in naivety.

This display just first letter of current running job. ex:
I run 'top' but is shows only 't' in titlebar.

newlines (it can also go with `print -n $pid`) ex:

mpeh:~> ps x|grep top
1943 pts/6    S      0:00 top
mpeh:~> pskill to

Oh, sorry, in double quotes you need ${${(@)${(z)1}:#*[[:punct:]]*}[1]}

i thought i'd give it a try and it worked pretty well for me except:

jo.animal:~> src
/home/jo/.zshrc:133: compinit: function definition file not found

whereas just straight sourcing ~/.zshrc (not from the function)
works fine. i'm sure i'm overlooking something stupid. any ideas 
anyone??

It's because `typeset -U path fpath ...' is executing inside the function
context and therefore turning all those arrays into local variables that
don't have their usual values.  I should have noticed this before.

There is no workaround for this using functions in zsh 3.0, so the `src'
function can't be used if the .zshrc is going to be read that version.
If only 4.0 will ever read it, you can change the call to typset to use
the -g option

	typeset -gU path fpath ...

and then all will be well.

Alternately, put the body of the `src' function in another file (called
for example `~/.zsh_reload') and then read *that* file with `source', e.g.

	alias src='source ~/.zsh_reload'

Oh, silly me.  Single-element arrays are treated as scalars, so if the
command consists of only one word, you get only the first letter, but
if it consists of multiple words you get the first word.  I never tried
it with a command with no arguments.

So try this:

preexec () {
  print -Pn "\033]0;%n@%m ${${(@)${(z)1}:#*[[:punct:]]*}%% *} %~\007"
}

I just now noticed that it's not working for 'two_or_more' word job ex.
If i run 'vi .Xresources .vimrc .slrnrc' it only shows 'vi' in titlebar.
With '$1' it works perfectly? (shows complete line).
Why is $1 bad?

Right, that's bothering me right now, too.

First I didn't understand it either, then I stumbled over more complicated
command lines with quotes and stuff in it.  For example, try:

 echo hi | perl -ne 'print "oops\n"'

This should just print:
 oops
but with <$1> in preexec it prints:
 
 "'>" pts/17 ~oops

I'd really get it to work the way you tried, but I can't figure it out. :-(
Any suggestions anyone?

Thanks,
 Andy.

} Right, that's bothering me right now, too.

The function as quoted is designed to show only the command name.

The ${...%% *} in the expression above strips off everything after the
first word.  Inside that, ${(@)...:#*[[:punct:]]*} removes all words that
contain punctuation (which would include file names with dots in them).

The intent was that, if for example you give a command such as

    CVS_RSH=ssh cvs update 
or
    ( scp some list of files remote:directory )

the variable assignments and parentheses will be discarded before figuring
out what command name to display.

} > With '$1' it works perfectly? (shows complete line).

} First I didn't understand it either, then I stumbled over more complicated
} command lines with quotes and stuff in it.

The real danger is that the command line will contain a control character
or the like which the terminal interprets, or (as in your next example)
that it will contain a backslash sequence like \n which `print' will turn
into something unwanted.

A secondary problem is that the command line may be much longer than you
really want to put into your title bar.  What if the command is a multi-
line `for' or `while' loop?

} For example, try:
} 
}  echo hi | perl -ne 'print "oops\n"'
} 
} This should just print:
}  oops
} but with <$1> in preexec it prints:
}  
}  "'>" pts/17 ~oops

This happens because the \n in "oops\n" gets turned into a real newline
by `print -nP', and the newline terminates the title bar string the same
way that the \007 would have.  A similar thing would happen if the command
contained an actual newline, such as a multi-line loop body would.

} I'd really get it to work the way you tried, but I can't figure it out. :-(
} Any suggestions anyone?

If you have zsh 4.0.x, you might try:

    preexec () {
      print -Pn "\033]0;%n@%m ${(Vq)2} %~\007"
    }

The doc for preexec says "the second argument is a single-line, size-
limited version of the command (with things like function bodies elided)".
The (Vq) means to render any control characters in a visible format and
to quote any special characters in the string with backslashes.

There isn't any simple way to get the equivalent in 3.x.
