ps http<tab> completion to get procees ID

ps http<tab> completion to get procees ID

[zzapper]

Hi
This works on my Cygwin zsh 5.0.8
but not on my Centos zsh 5.0.7

what needs to be configured to get this marvellous feature to work?

ps mintty<tab>
   5836   1   5836   5836   ?   1049708   Jul   22   /usr/bin/mintty

   7328   1   7328   7328   ?   1049708   Jul   22   /usr/bin/mintty

   7876   1   7876   7876   ?   1049708   Jul   22   /usr/bin/mintty

   8048   1   8048   8048   ?   1049708   Jul   22   /usr/bin/mintty

   8124   1   8124   8124   ?   1049708   Jul   27   /usr/bin/mintty

   9128   1   9128   9128   ?   1049708   Jul   22   /usr/bin/mintty

Install 5.0.8 on your CentOS?

There were a lot of changes to _main_complete as well as to _ps between
the .7 and .8 releases.  Debug trace is radically different for the two.

It *seems* to work to just copy the 5.0.8 _ps file into fpath somewhere
ahead of the 5.0.7 version, but I can't promise something obscure won't
go wrong.

It seems to only complete processes from the current terminal.  For
example, if I just do 'ps <TAB>', I get:

    % ps
    ...
    > process ID
    23620 pts/11   00:00:00 zsh
    23647 pts/11   00:00:00 zsh
    23648 pts/11   00:00:00 ps
    > all matches
    ...

I guess that's due to _pids running 'ps' without further arguments.
Shouldn't the command be configurable?  I'd love to have it show all
user processes (or even all processes when sudoed).

For 'kill' we already allow customizing the listing format via the
'command' style; I suppose it would be nice to support the same here.

Cheers,

Daniel

It is configurable. The command style is not specific to kill.

I'd recommend using tag labels and use the _next_tags widget if you want
it to pick-up a wider range of processes. Something like the following:

zstyle ':completion:*:(kill|lsof|ps|ss):*:' tag-order processes:-tty 'processes:-mine:user\ processes' 'processes:-all:all\ processes'
zstyle ':completion:*:([sl]trace|truss|gcore|gdb):*:' tag-order processes:-mine 'processes:-all:all\ processes'
case $OSTYPE in
  *bsd*)
    zstyle ':completion:*:processes' command 'ps -o pid,ppid,state,start,args'
    zstyle ':completion:*:processes-mine' command "ps U $EUID -o pid,ppid,state,start,args"
    zstyle ':completion:*:processes-all' command "ps A -o pid,ppid,state,start,args"
  ;;
  *)
    zstyle ':completion:*:processes' command 'ps -o pid,s,ppid,stime,args'
    zstyle ':completion:*:processes-mine' command "ps -u $EUID -o pid,s,ppid,stime,args"
    zstyle ':completion:*:processes-all' command 'ps -e -o pid,s,ppid,stime,args'
  ;;
esac

Thank you!
