Yes it is very difficult, at least with a RegEx. For the record, for an
in-house interface I wrote, I did it by making bacula-dir.conf contain just:
@|"sh -c 'for f in /etc/bacula/bacula-dir.d/*.conf ; do echo @${f} ; done'"
and then maintain one file per stanza in /etc/bacula/bacula-dir.d. Each stanza
is in a file named <type>.<name>.conf, so we end up with files like:
client.wwsv01.conf
job.wwsv01.conf
job.restorefiles.conf
pool.weekly.conf
And I wrote some PHP code to parse an individual stanza into an internal data
structure. From a web interface, modifying an individual object/stanza then
becomes a matter of just rewriting the single config file, rather than having to
parse/rewrite the entire bacula-dir config file. If the web interface doesn't
have capability (or need) to write to a given stanza, then those files can be in
whatever format is desired (with weird spacing etc). And if the web interface
is writing to the files, it can write in a consistent easily parseable format
that is valid for bacula, but makes it simpler for it to read later. It just
kinda works; sure, an admin could screw it up, but when is that never a problem?
That may not help if you're wanting to parse an existing bacula-dir.conf though,
so I may be wasting my breath here :)
