[chef] Re: Re: RE: Re: Most efficient way to handle text in config files (without a template)

[Jesse Campbell < >]

The way I handled it doesn't at all meet your requirement... i did use
a template.
It isn't the cleanest, and I wish I could switch to the Util::FileEdit
method, as that is much cleaner... but it doesn't seem to serve the
same purpose.
This checks if my line text exists, and if it does not it adds it at a
specific point that I specify. If you didn't care where in the file it
went, you could skip the insertpoint piece, and just append to
'output'

Here's the template:

<% output = File.read(@oldfile) -%>
<% @insertlines.each do |line| -%>
    <% unless (output.match(/^#{line['text']}$/i)) then -%>
        <% output =
output.sub(/^(#{line['insertpoint']})$/,"\\1\n#{line['text']}") -%>
    <% end -%>
<% end -%>
<%= output -%>
