The completion for infocmp won't work in Debian

[Morita Sho]

Hi,

I noticed that the completion for infocmp won't work in Debian.

  % infocmp [TAB]

will not complete any terminfo that is available in the system.

In Debian, terminfo files are placed on /lib/terminfo and /etc/terminfo.[1]
But infocmp completion won't searches these directories.
According to Completion/Unix/Type/_terminals [2], the current search path is specified as follow:

  #compdef infocmp -value-,TERM,-default-
  local desc expl
  desc=( $TERMINFO ~/.terminfo $TERMINFO_DIRS /usr/{,share/}{,lib/}terminfo )

Could you add /lib/terminfo and /etc/terminfo to the search path for infocmp completion?

Depending on the installed packages, this is indeed the case.

That's not completely true. Debian places terminfo files only in
/lib/terminfo and /usr/share/terminfo. The only file in /etc/terminfo
shipped by Debian is a README file.

/lib/terminfo contains only the most important terminfo descriptions
and is installed by default. /usr/share/terminfo is only filled if you
also install additional terminfo descriptions from the ncurses-term[2]
package -- which I do on all my systems, hence it worked for me. :-)

/etc/terminfo is for system-local terminfo descriptions and to be used
by the local admin, not Debian. See /etc/terminfo/README.

But Morita is right in the sense that Debian by default only ships
terminfo descriptions in /lib/terminfo and that it also looks for them
in /etc/terminfo.

Actually this has already been reported against Debian's zsh package
as http://bugs.debian.org/600151 a while ago, but we seem to have
missed it as "to be reported to upstream". Thanks for bringing this
to my attention again!

I'd be happy about this patch being applied to zsh in general. (BTW: I
expect that the order of the directories is not relevant here.)

	Kind regards, Axel (with his Debian Zsh Team hat on :-)
