vcs_info problem

vcs_info problem

Hi,

I'm using Zsh 4.3.9 and trying to use vcs_info. I added the following to my
.zshrc as documented in zshcontrib.

    autoload -Uz vcs_info

    zstyle ':vcs_info:*' actionformats \
        '%F{5}(%f%s%F{5})%F{3}-%F{5}[%F{2}%b%F{3}|%F{1}%a%F{5}]%f '
    zstyle ':vcs_info:*' formats       \
        '%F{5}(%f%s%F{5})%F{3}-%F{5}[%F{2}%b%F{5}]%f '
    zstyle ':vcs_info:(sv[nk]|bzr):*' branchformat '%b%F{1}:%F{3}%r'
    precmd () { vcs_info }
    PS1='%F{5}[%F{2}%n%F{5}] %F{3}%3~ ${vcs_info_msg_0_}'"%f%# '

But it gives me the this error.

    /.zshrc:358: unmatched "

So I tried a simpler approach:

    autoload -Uz vcs_info

    precmd () { vcs_info }
    PS1='${vcs_info_msg_0_}'

But if I use this vcs_info_msg_0_ is not expanded and stays in the prompt all
the time.

    ${vcs_info_msg_0_}

If I execute vcs_info_lastmsg it gives me the correct result when I'm in or
outside of a repository.

Thanks for your help,
Simon

If you want to use $vcs_info_msg_0_ like this, you will need to use:
    setopt promptsubst

Thanks for your answer,

but when I remove the double quote it still doesn't work and I get this error:

    unmatched '

I took the example from the zshcontrib man page so it looks like there is an
error.

Thanks, setting promptsubst worked fine.

I followed the introduction in the zshcontrib man page. Would it be possible
to add this information there so other users can set it up without any
problems?

Just curious, what other ways to use vcs_info than ${vcs_info_msg_0_} exist?

Thanks,
Simon

Oops, yes. That's obviously wrong. Thanks for noticing.
That should be: PS1='%F{5}[%F{2}%n%F{5}] %F{3}%3~ ${vcs_info_msg_0_}%f%# '

Absolutely. I thought I had mentioned it. Seems like I forgot.

Patch for both issues included below.

Well, a lot of people (me included) build their prompt in precmd().
That way you can always get the fresh value out of $vcs_info_msg_0_
without having to use prompt_subst. Here is how I am building my
prompt, if you're wondering what I'm talking about:

 Obviously, the last two lines are there for demonstration: You need to
 call var(vcs_info) from your var(precmd) function. Once that is done you need
 a tt(single quoted) var('${vcs_info_msg_0_}') in your prompt.
 
+To be able to use var('${vcs_info_msg_0_}') directly in your prompt like
+this, you will need to have the tt(PROMPT_SUBST) option enabled.

 Now call the tt(vcs_info_printsys) utility from the command line:
 
 example(% vcs_info_printsys

Thanks for your quick help. Works perfectly.

Thanks, this sounds very interesting.
