Re: Tables in PODs

I have attached a specification for them for your review. There is a perl 6 specification for tables. See https://raw.github.com/perl6/specs/master/S26-documentation.pod and an implementation for Perl 5, at least for HTML: https://metacpan.org/module/Perl6::Pod However, the big question I don't know the answer to is if anyone has implemented code to output tables to man pages. man can do tables (very nicely), but I know approximately zero roff, so I don't know how easy it is (or isn't) Or how good plain text output for tables is.

I misunderstood, sorry. parse_from_file() does indeed invoke the parser with the appropriate actions, but what you meant was that Pod::Parser's null parser, when not subclassed, just printed the POD back out again, so you could use it as a way to extract the POD from a file. I believe Pod::Simple's null parser does nothing at all, so you get an empty file. Yes. I think that's an incompatibility. If I turn on DEBUGing, it's doing a lot. Is there some trivial way to extract the pod? So no one thinks there is a trivial way to get this extraction. Would someone make a suggestion as to the easiest way to do so using modules that will continue to ship with the Perl 5 core (unlike Pod::Parser)? No-one answered this, did they? Is it possible to extract the pod by subclassing Pod::Simple, and the subclass being a null parser that prints out the Pod that it was given? Nicholas Clark

I have often found such lines *in other programs* useful for sorting out bugs. I've never tried debugging the podlators, thankfully! :) My inclination would be to add the flag for such packagers to use, but I'm not particularly invested in the problem. Me too. In that my experience and situation parallels Ricardo's. A flag for people who know what they are doing to disable the generation of comments feels like the best compromise, as such people likely also know how to debug their toolchain if they get a problem.

Attached is the current pod for podcheck.t I have things I'd like to change in Pod::Checker, but it seems to be considered untouchable until the move to Pod::Simple. It somewhat is, as a side effect of the attempt at having a consistent policy on what is upstream. Pod::Checker is part of the Pod-Parser distribution. The core's who owns what file, Porting/Maintainers.pl, says that Pod-Parser isn't maintained in core, and that upstream is MAREKR. MAREKR says that is (well), effectively dead. So the core policy works out as send patches to MAREKR and MAREKR's policy works out as no thanks. Which isn't exactly ideal. At which point, the two obvious routes forward to resolve this are either a: move to maintaining Pod-Parser as part of the core or b: more to eliminating the need for Pod-Parser and the consensus seems to be that (b) is far less insane. I think that what's then gone wrong is that no-one wants to start on it, but given that it is the future, everyone thinks that doing anything in the direction of (a) is a waste of effort. Which stalls. Nicholas Clark

This seems like a useful feature, which is supported at least in html. Yes, I disagree with this as well and have POD conversion software that relies on being able to use L for man pages, URLs, and several other things that aren't POD. If you have tools available to create real links for man pages, you want to allow specifying man pages in L, since otherwise you have to make guesses at whether something(1) is a man page reference or something else. So this is a bad thing to deprecate. Agree. As I loathe heuristics, because they mean that you can't predict how your document will be parsed, and effectively mean that you can't write some totally legitimate code examples without it mistakenly being treated as a link.

Core doesn't mind, as long as there's an answer. (The revised layout of ext, dist and cpan makes this a lot easier. Whilst said files *are* currently under pod/ they don't have to stay there. I believe that I can patch it so that the core's build automatically grabs them from the appropriate dist dropped into cpan/, and which point it's just as easy to keep canonical as every other directory in cpan/) So are you saying that it should remain in the Pod::Simple distribution? No, I'm saying that giving core one more thing to sync up is not an issue that should affect the decision making. I don't have an opinion on where the right place *is*. I'm perfectly happy for it to be in distributions on CPAN, if that's the right place. Although I note (without investigating) http://perl5.git.perl.org/perl.git/blob/HEAD:/Porting/Maintainers.pl#l1295 # XXX these two files correspond to similar ones in blead under # pod/, but the blead ones have newer changes, and also seem to # have been in blead a long time.

Re: podlators/Pod::Simple backwards compatibility (was: Re: [PATCH] 5.8.8: Debian patches)

Also specify INSTALLDIRS=perl in Makefile.PL when appropriate. There remain a few Pod::Parser oddities not supported: parse_from_file and parse_from_filehandle used to take an optional initial hashref specifying options; the only one I actually saw code for was {-cutting=0} which would make the parser assume the file starts with pod, not with perl code. There was code to allow parse_from_file/filehandle to be recursively called from a handler that would make the parser continue with the new file and then switch back to the original file, but preserve the same output file unless a new output file were specified. I can't offhand think of any use at all for this, much less one relevant to podlators. Pod::Parser would close the input or output file if it opened it itself rather than being passed a handle. Did anything come of this? I was wondering what subtle but known differences exist between the behaviour of the POD modules in 5.8.8, and those in blead. Nicholas Clark

Also, the patch as supplied was intended to give the minimum changes to the POD part of the code whilst keeping everything working, more as a proof of concept than a final version. If the chosen path is to drop the use of HTTP:Daemon and associated modules, then I believe that it's possible to clean the code still further by simplifying the API between the two halves. What I feel is particularly hacky is the package Pod::Webserver::Response. HTTP::Response had proper getter/setter methods, but Pod::Webserver only needed to use the setter methods. So for maximum laziness I used AUTOLOAD to emulate the setters, and the other HTTP::* emulation code pokes around directly in the object, rather than using methods. To me this feels unclean. Although keeping things this way means that the rest of Pod::Webserver can go back to using HTTP::* proper if it wants. I'm not sure if that's really needed. Nicholas Clark
