Call for neat examples

Call for neat examples

[Timothy J Luoma]

Hey folks

	As Bart just pointed out, there are many different pieces of zsh  
that even someone who has used the shell for awhile doesn't necessarily know  
about.
	
	I was wondering if there was any interest in getting together a  
'best of Zsh Uses' file.... I'd be happy to put it together.
	
	I'm thinking of nifty little functions and scripts that illustrate  
tricks and just plain good use of the functionality (heh... pun intended) of  
zsh.
	
	Commented code, of course, will be the most easily reusable.... but  
if you can at least give an overview it will be appreciated.
	
	If you're interested, please reply (using this Subject: line) and  
I'll start a summary file).
	
	Thanks!
	
		TjL

How will you make it available?  Perhaps on a webpage?

Sure.  I'm "maintaining" the ZSH web pages as it is...

But people have to submit some first :-)

So far I haven't gotten a single entry.

	i've thought about this a lot, and i don't know if it will work, or at 
least, if it will work and still be a "zsh" page.  most of the functionality 
that my on functions provide, at least, are only somewhat zsh-specific; zsh 
makes it much easier to do things, but most of the times (in my functions) it 
doesn't do everything itself, or in a zsh-specific way.
	
	for example, here's a quick (well, not so quick, because I was making a 
really stupid mistake) function called nobrs that i just wrote for myself:
	
#!/usr/local/bin/zsh
nobrs () {

case ${1} in 
   -[0-9]*) lines=${1#-} ; shift ;;
    *) lines=2 ;;
esac ;

while [[ -n ${1} ]] ; do
   awkstring="awk 'BEGIN {count = 0;} /^$/ {count++; if (count < ${lines}) 
print; next;} {print \$0; count = 0;}' ${1}" ;
   shift ;
   eval ${awkstring} ;
done ;

}

	nobrs by default removes any newlines more than 2 from whatever file(s) 
it gets on the command-line; if the first argument is a hyphen followed by any 
digits, it sets the maximum number of consecutive linebreaks to the number 
formed by those digits.  most of the work, however, is done by an awk 
command-line.  (tangentially, is there any way to get rid of that awk line and 
do this all in zsh?)  the while...done and case...esac loops are shell tricks, 
but aren't zsh-specific; ditto for the ${1#-}.  really, this is a ksh script 
that happens to be a zsh function because i use zsh.
	while this would have been something i would have loved to have seen 
when i was first scripting, then, it wouldn't have been something i would have 
looked for as a "zsh script", or expected to have found as such.  there are, of 
course, examples that would use zsh-specific features, but in most cases, i 
think that those features would be used minimally in comparison to the more 
general parts of the function.
	i guess my question is, are you envisioning this as a example-based 
guide to zsh features, or just as a collection of cool functions used by people 
who use zsh?  i'd love the former, of course, since i know that i definitely 
underuse zsh features, but have a feeling that it would turn into the latter.
	not that there's anything wrong with that, of course; i would also love 
to just get a look at some nifty scripts in general.
	
	does anyone else have any input on this?

I would like both.

I'm always amazed at people who know how to use Y can do with Y, whether Y  
is zsh, sed, perl, etc.  So I would like nifty scripts of any and all kinds,  
as well as those which say "And *this* particular feature is zsh-specific or  
zsh makes this much easier.

I submitted some stuff many years ago to the old webpages.
I can't say they're great examples of zsh'ing though :)

I've sent several examples to TJL.  Haven't seen them show up anywhere,
though.

That's true, and right now there are about 4 folks who have submitted stuff  
(Bart having submitted more than all other combined).

I had to go out of town last week so I haven't had time to do anything with  
them, but I'll try to get something started this week.
