MHonArc Users,
Since many users are using Perl 5, there is a potential conflict
when specifying MIME filters and charset filters. For example,
the current way is the following:
<mimefilters>
text/plain:mypack'filter:myfilters.pl
</mimefilters>
The problem is that a ':' is used to delimit the fields. However,
this will conflict if Perl 5 package qualifiers are used. Example:
<mimefilters>
text/plain:mypack::filter:myfilters.pl
</mimefilters>
Mhonarc will interpret the "::" as field delimiters.
My questions to you is what is a reasonable solution to the
problem? Should a new field delimiter be used? If so, what
about other resources that use ':' as a delimiter, but have
no conflict since Perl routines are not being specified (egs:
labelstyles, fieldstyles, etc). Should mhonarc try to be
intelligent and treat "::" as a package qualifer and a single
':' as a field delimiter? Leave things as-is and require
users to use the Perl 4 syntax?
I think it is okay to require Perl 4 syntax (Documentation) but
I would not mind if the Perl 5 "::" would be also supported.
Comments are welcome since changes may cause compatibility
problems with some users.
--ewh
P.S. Another questions is retaining Perl 4 compatibility still
needed? Although MHonArc will probably not take advantage of
Perl 5 OO constructs for awhile (too much rewriting at this time),
other Perl 5 enhancements may be nice to use.
I had the impression that several postings here mentioned that they
use Perl 4. Maybe we keep Perl 4 compatibility for V2.x and for V3.x
and higher Perl 5 will be required.
The biggest advantage I see when switching to Perl 5 are the *DBM
modules. They would let mhonarc archive grow to several thousand
messages (thanks to multipage indexes) and prevent that read/write
.mhonarc.db files that are several 100 kilobytes big just to add
one message.
