It is Pd, so I think we should at
least make
an
effort to
make things easy to parse in Pd.
I tried
your parser
using data that is probably closer to
what
we
might use, and
it didn't work at
all. If someone
can get a
Pd parser working that can handle the
commas
well,
then I
would be OK using commas in the meta
data
format.
Here's my data: tags - pure data, frequency
modulation,
synthesis
Hi Hans, I wouldn't expect my
example
to work as a general solution. If you
want a general solution, I'd be happy to
take a
stab
at it, but you
haven't said what you want Pd to do with
the
data
example you've provided
above.
Ah, sorry, I thought you'd followed the
object_db.tcl
plugin discussion and the [pd META] discussion
with
Frank. Basically, the object_db.tcl
plugin builds a
multilevel menu for finding objects based on
tags.
I'm
am sure people will think of other uses for
the
tags.
Frank suggested using comma separated tags in
his [pd
REFERENCE] format, the PDDP group came to the
conclusion
that the meta data should be easily parsable
by Pd,
and I
still think that's a good idea.
So the idea is to have every help patch have a
[pd
META]
subpatch, and in it, have a comment with
tags.

Oh, ok. I'll have a look at that
discussion.

Yes, I have seen this discussion. But I'm still
confused: are commas
a problem in tcl? If not, I still don't
understand the problem (see
attached).
<file.pd><parser.pd>
Tcl's not the problem, its Pd's parser. It interprets commas as a separator between messages. Since there isn't an escape mechanism, it means handling commas, semi-colons, etc. is difficult unless you are wanting the behavior of Pd's parser.
If we use commas as the delimiter for individual tags, then just removing the commas means you don't know if you have multi-word tags or just single word tags. So if you have:
tags - frequency modulation, synth
and its parsed as:
tags frequency modulation synth
then key information is lost.
Ok. (see attached)
