make completion on OpenBSD

make completion on OpenBSD

[Jukka Lehti]

Hi,

I've been using following in my ~/.zshrc to get make
completion right:

compctl -s "\$(awk '/^[a-zA-Z0-9][^\/ \t]+:/ {print
\$1}' FS=: [mM]akefile)" -x 'c[-1,-f]' -f --
{,g,gnu,p,v}make

And this works just fine on Linuxes (RedHat, Debian).
However, after I installed OpenBSD 3.1 and zsh-4.0.4,
the above behaves strangely:

root@bsd:~>make <TAB>awk: i/o error occurred while
closing /dev/stdin
 input record number 538, file Makefile
 source line number 1
p
dep dep-files depend
root@bsd:~>make dep

Makefile is the top-level Makefile from linux-2.4.18.

Any suggestions?

Thanks.

Ok, now I finally got it!

I think I'll use compctl for now, I have one system
where only zsh3 is installed. I guess compctl will not
be removed from zsh (ever/soon)?

They seemed to work very well, make was an exception:

if in a Makefile is line

FOO :=

make <TAB> lists that also as possible completion,
although "make FOO" is meaningless.

One thing I really miss from default completions is
the "cd ..<TAB>" producing /. With Finnish/Swedish
(probably German, too) keyboards / is shift+7 and
that's quite a penalty.

Anyway, thanks again!

That's what I was trying to tell you.  If you remove
the backslashes, then the $(awk ...) runs at the time
that you *define* the compctl, rather than at the time
that you attempt a completion.  That's the effect of
having it inside double quotes.  So without the
backslashes, it only "works" if you run the compctl
command in the same directory that holds the Makefile.

Furthermore, with the backslashes present, they should
be getting removed by zsh at the time it parses the
double quoted string, long before awk gets anywhere
near it.  The whole thing with the backslashed dollar
signs is a wild goose chase; the problem is somewhere
else, and it's almost certainly something to do with
awk.

After loading the new system with `compinit', unset
the elements of the _comps assoc corresponding to the
compctls that you prefer to use.  E.g.

 unset '_comps[foo]' '_comps[bar]' '_comps[etc]'

or (shorthand)

 noglob unset _comps[{foo,bar,etc}]

There isn't any automated way, but it's possible that
there are zstyle commands you could use to get the
behavior that you want -- many of the new completions
are very configurable.  Ask on the list about a few
that are most important to you.  Even if zstyles are
not available it's possible that your different
behaviors are generally useful enough to get folded
into the distribution.

Argh.. This seems to be hopeless. If backslashes are
not used, on Linux root gets an error:

/root/.zshrc:613: no match

Yes, OpenBSD has awk derivate from 4.4BSD, gawk is a
seperate package. (gawk is about 200k, awk 100k!)

Anyway, I've made some silly mistake, now it seems
that following works on Linuxes too, after all:

compctl -s "$(awk '/^[a-zA-Z0-9][^\/ \t]+:/ {print
$1}' FS=: [Mm]akefile)" -x 'c[-1,-f]' -f --
{,g,gnu,p,v}make

(So backslashes not needed before $'s. Why backslashes
do not work with BSD awk is a mystery.)

Sorry for wasting everyones time here.

I would love to do that, but I have about 50 compctl
rules for which I've spent countless hours and some of
those behave different than the newer completion
system defaults. I haven't found a way to use the
newer system and override some of those rules with my
own compctl rules. Maybe I should "port" my compctl
rules to compsys rules (I presume they can be override
system defaults?), but it takes time if it cannot be
automated.

Thanks.

One possible difference is that awk is definitely GNU awk on RedHat, but
it may be something else on OpenBSD.  Have you tried running just the awk
expressions on both platforms to see if the output is different?

awk '/^[a-zA-Z0-9][^\/ \t]+:/{print $1}' FS=: [mM]akefile

In particular I'm wondering if you need a literal tab instead of \t in
that character class on OpenBSD.

In any event, since you're using zsh-4.0.4, why not abandon your compctl
entirely and enable the newer completion system?  It includes a very
detailed "make" completion.

No. I did "setopt > opts" on both machines and diff
shows that the files are identical. Both machines have
zsh-4.0.4. OS are Red Hat Linux 7.3 and OpenBSD 3.1,
both pretty much at out-of-box state.

Removing the backslashes is almost certainly the wrong thing to do, given
that you have double quotes around the "$(awk ...}".

More likely you should check whether the values of your setopts are the
same on OpenBSD as they are on Linux.  E.g., does one have sh_word_split
set and the other not?

Well, after removing backslashed before $'s it started
to work on OpenBSD but broke on Linux. I guess I'll
set up:

[[ "`uname`" = "Linux" ]] && ... || ...

if nobody has better ideas.

Cheers!
