"converting"

hi - 

i found a neat looking prompt written for bash that i'd like to use with
zsh. the whole thing looks like:


CW="\[\033[0;1;37m\]"   #Color for [ and ]
CB="\[\033[0;1;34m\]"   #Color for label
CR="\[\033[0;1;33m\]"   #Color for value
NC="\[\033[0m\]"        #No Color
MT="\[\033[0;0f\]"      #Move to the top
SP="\[\0337\]"          #Save Position
RP="\[\0338\]"          #Restore Position
CL="\[\033[K\]"         #Clear Line

TOPBAR="$SP$MT$CL$CR User: $CB\u$NC$CR  Host: $CB\h$NC$CR Time:
$CB\t$NC$RP"
PS1="\n$CW[$CB\w$CW]$NC$TOPBAR"

i'm not really sure at all where to start with this, the only thing i
would really know how to do is "translate" the "\u,\h,\w" to something
zsh understands. can someone point me to a good place for starting to
"convert" this?

Thanks!

Jo

hrmm perhaps TFM?  search for 'PROMPT EXPANSION' in the zshall man page.

       %n     $USERNAME.
       %M     The full machine hostname.
       %m     The  hostname  up to the first `.'.  An integer may
              follow the `%' to specify how  many  components  of
              the hostname are desired.  With a negative integer,
              trailing components of the hostname are shown.

as far as \w, zsh gives a lot of options for how to display the working
directory. i suggest reading the man page.

looking at other peoples' zshrc files can be very helpful as well.
check dotfiles.net, and do searches on google.

zsh is (IMHO) more flexible than bash as far as doing prompts.

also, you don't need to do as much fancy stuff to put stuff in the xterm
titlebar.

i have:

PS1="%B%m%b%# "

(hostname in bold, percent as a regular user, pound sign (#) as root) as
my prompt, and then:

case $TERM in
        rxvt|xterm*)
                precmd () {print -Pn "\e]2;%n@%m%#  %~ %l  %w :: %T\a"}
                preexec () {print -Pn "\e]2;%n@%m%#  <$1>  %~ %l  %w :: %T\a"}
        ;;
esac

(if i'm in rxvt or xterm put fancy crap in the titlebar).

right, i just said these were about the only things i knew how to
"translate" from the prompt above.

ok, let's try the question again... the problem with the above prompt
(assuming you change the \w etc to %~ or whatever) is this:

.zshrc:13: bad math expression: operand expected at `\[\033[0;1...'

i'm not sure whether this is because i have a certain combination of
setopt's or am lacking some setopt's[1] or the control codes need to be
expressed differently etc.

also, the prompt is neat but i'm not about to read TWFM to figure out
what i need to do to get it to work in zsh. :)

the above prompt doesn't put anything in the xterm titlebar. it keeps a
"floating" bar with username/host/time in the terminal window. fire up
bash and try it. ;)

sorry - i misunderstood. i'm sure someone on the list will know better
(and i'll see if i can figure it out), but you might read the howto here
as well:

http://www-106.ibm.com/developerworks/linux/library/l-z.html?dwzone=linux

i'm pretty sure it's just a matter of quoting the escape codes correctly
for zsh.

looking through the examples of others is still a good idea since plenty
of people have similar things in their prompts.

i also think you should switch the $TOPBAR thing to going through precmd
- i think it will simplify your life a lot.

thanks will - i'll have a look and see what i can come up with (in
regards to using precmd as well).

You might want to take a look at the prompt theme system supplied with 4.0
onward.  It's described in the zshcontrib manual page.  The functions live
in the Functions/Misc directory of the source code and are probably
installed somewhere under /usr/local/shar/zsh/<version>/functions.

If nothing there fits, you should be able to add your own prompt theme
along the lines of one of the existing ones, which could be added to the
distribution.
