exec GIT Variable PS1

[MaTi Villagra]

Hello I'm trying to push PS1 variable at .bashrc file 

    exec { 'GIT PS1 Variable':

    cwd => '/home/developer/.bashrc',

    command => '/bin/echo "PS1='[\u@\h \W\$(__git_ps1  " \"" (%s)"\"")]\$ ' " >> /home/developer/.bashrc',

    user => developer,

    group => developer,

   }

But client side  I get 

Dec 11 10:15:43 glb7240 puppet-agent[19762]: Could not retrieve catalog from remote server: Error 400 on SERVER: Syntax error at '['; expected ']' at /etc/puppet/modules/defaults/manifests/bash-extras.pp:53

If I copy command it work perfectly. Any toughs  ? 

Thanks. Appreciate.

The single quote following PS1= closes the string and the next character
puppet parser sees is [ -- that's what it seems to complain about.

Thanks,

You're using single quotes for your Puppet string, but you've got single quotes in your bash PS1 line as well, so it's confusing the Puppet parser. You've got a single quote after the " [ ", so Puppet is probably interpreting the rest of the line as an array, which is why the error is complaining about a missing " ] ".

This function might help you get your escaping correct:

Thanks for the help.  PS1 is confusing puppet parser as Luke suggest, 

For example I was trying to start from a single command like 

 command => "echo PS1='a' >> /home/developer/.bashrc" 

works perfectly. 

I also try to define as a line with no luck using http://projects.puppetlabs.com/projects/1/wiki/simple_text_patterns 

  line { 'PS1 git variable':

    file => '/home/developer/.bashrc',

    line => "PS1='[\u@\h \W\$(__git_ps1  " \"" (%s)"\"")]\$ ' ",

    ensure => present,

   }

Thanks!

First of all, cwd points to a file in your case and not to a directory.

Next, you should escape quote characters, so if u use singlequote (') in
a puppet, which you should, then any occurrence of singlequote inside
your intended string should be escaped. So, your resource should look
like this:

exec { 'GIT PS1 Variable':
cwd => '/home/developer',

command => '/bin/echo "PS1=\'[\u@\h \W\$(__git_ps1 " \""
(%s)"\"")]\$ \' " >> /home/developer/.bashrc',
user => developer,
group => developer,
}

Note the escape (\) character in:

"PS1=\'

and:

$ \' " >>

Jakov, yours suggestion works perfectly. 

The only thing missing is that exec will write the only every time puppet parser goes by. 

So I will code a onlyif condition under that exec. 

I will poste the final result here. 

Thanks!
