Re: non-convergent file edit?

[Brendan Strejcek]

Here is my contribution. It edits a file, then, if any edits happened,
it updates a datestamp in a comment. Not sure if you are trying to solve
a similar problem, but another (working) example can't hurt.

control:

    actionsequence = (
        editfiles.first
        editfiles.second
    )

editfiles:

    first::

        { /var/tmp/junk
            Backup "false"
            Prepend "junk" # make sure an edit happens, just for testing
            DefineClasses "edits_happened"
        }

    second::

        # if edits happened above, update the datestamp
        { /var/tmp/junk
            Backup "false"
            BeginGroupIfDefined "edits_happened"
                BeginGroupIfNoLineMatching "^# cfengine edit .*$"
                    Append "# cfengine edit $(day) $(month) $(year)"
                EndGroup
                ResetSearch "1"
                LocateLineMatching "^# cfengine edit .*$"
                BeginGroupIfNoMatch "^# cfengine edit $(day) $(month) $(year)$"
                    ReplaceLineWith "# cfengine edit $(day) $(month) $(year)"
                EndGroup
            EndGroup
        }
