Unfortunately, none of that is really analogous to Stdlib::File_line, which manages *just* one line in a file, without managing the rest of the file's content. That's a pretty strange thing to do in the Puppet scheme of things, actually, but I suppose it can be useful.
I am not aware of any existing, publicly available module providing a type that manages blocks of lines in a manner analogous to Stdlib::File_line. There are several possible approaches that might work instead, depending on the details of the problem, among them: - Manage the whole file (best, if it is feasible). Templates and/or Concat fit right into this. - Put everything on one line and manage it via Stdlib::File_line. That assumes the line breaks are optional (or can be replaced with something else), which is often true, but not always. - Put the managed content in a separate, wholly-managed file, and include it into the target via a target-specific inclusion feature. For instance, some configuration file languages have an 'include' statement that interpolates external files (much like the C preprocessor's #include directive). Better, some programs automatically read all files from a given directory. If none of those are suitable then it's a very unusual case; the best available option may then be to build what you need yourself.
