Pierre Habouzit: back from the deads, screenrc, zshrc
Well, my DSL provider killed my connection for 10 days, and then I had some vacation ...
Long time no see.
Though, I've played with my dotfiles recently, and I set up some really nice things, picked from the web.
Screen and zsh cooperation
The one I find the best is the tight collaboration between screen and zsh to have nice labelled windows in the screen status line.
You have to do this like that :
# in your .zshrc, add the following code to you preexec :
preexec ()
if [[ "$TERM" == "screen" ]]; then
local CMD=$ 1[(wr)^(*=* sudo -*)]
echo -ne "\ek$CMD\e\\"
fi
# and this code in order to reset the title when zsh gets the hand back
if [[ "$TERM" == "screen" ]]; then
PROMPT="$ PROMPT % ^[kzsh^[\\% "
fi
Then, you can have in your .screenrc some dark margic like :
bind s select zshwhich make
Ctrl-A s find your first available shell (really nice).
Make Shift+PgUp/PgDown work in screen
well, this is complete dark magic, but it works :
# tell screen that you term can scroll termcapinfo xterm ti@:te@ # bind Shift+PgUp/PgDn bindkey -m "^[[5;2~" stuff ^b bindkey -m "^[[6;2~" stuff ^fAnd another great setting is altscreen :
# Support alternate screens so that, for example, when you # quit out of vi, the display is redrawn as it was before vi # redrew the full screen. altscreen onThough, now,
Shift-Tab doesn't work anymore in screen, and since in vimrc I have things like :
" Tab Key magic ... vmap <tab> >gv vmap <bs> <gv
function! CleverTab()
if strpart( getline('.'), col('.')-2, 1 ) =~ '^\s*$'
return "\<Tab>"
else
return "\<C-P>"
endif
endfunction
inoremap <Tab> <C-R>=CleverTab()<CR>
inoremap <S-Tab> <Tab>
"it's quite important that Shift+Tab works ... zsh does not eat non "\n" terminated lines I don't like the option
setopt no_prompt_crthat tells zsh no to print a "\r" before each prompt : I have a rprompt, and if a command (e.g.
echo -n "f*****g command") is performed just before a shell prompt display, then my rprompt is wrapped, it's ugly.
but printing a "\r" each time eats the line if no "\n" was present, which happens sometime, and makes you think the command you launched failed.
I found that jewel on the zsh-users MailList :
precmd()
local escape colno lineno
IFS='[;' read -s -d R escape\?$'\e[6n' lineno colno
(( colno > 1 )) && echo ''
Basically, it checks before writing the prompt if the current column position is 0, and if not, it prints an "\n". I guess it may exists some races if you have a background job, but for alldays use, it's perfect.

I'm sorry.
in the next 18 or so months of being in the queue. And even more Debian work after that, for sure 
Guys, rock on!
