most of the doc is still manually created, the function descriptions and args are usually don't take much space. But I do agree that it helps a lot. At least to create the basic docs and extend them afterwards as time allows. >>When such a >>doc is created for the first time, it's copied away to the place where >>the final pod should be and filled in with manual craft.

Two problems here: 1. the pods will be read by people, and perldoc won't know how to handle autodoc. Or even worse those reading the source will have to get through a lot of noise. 2. I don't believe it's possible to use the generated docs without manual adjustments. You forget that at the maps level we change arguments, for which there is no docs. Also we don't want to be stuck with whatever comments httpd people have written, because they might be not good enough or for some other reason we will want to change them. Restricting us to a use as-is doesn't sound like a good idea to me. > Maybe your idea with diffs it better, because there isn't so much noise in > the pod itself, on the other hand you have to maintain serveral copies of > every file and I am not sure how much work it will be to manualy review > after the diff. No, you maintain a single copy of each file. The autogenerated copies are autogenerated and you want to keep the previous copy so you can run the diff. Notice that you will have to diff only when you update the maps (running source_scan), and the diff will be autogenerated and files automatically replaced. > That's only a rought idea, maybe somebodyelse has another idea how to handle > this?

Parsing now works correct, but I have add the special > handling in the code generator. Why not expanding this as a macro, which PPPort supplies. Does your version of source scan support macros expansions? So shouldn't this happen automatically? Actually you don't need PPPort for this, just including the right perl header files. >>Another question I have: >>In order to use ExtUtils::XSBuilder we need to have it in mod_perl.

I guess the instructions would be great in any case. I hope soon I'll have time to play with it. >>And of course we need to discuss the template, but this can be done >>later when and if we start deploying ExtUtils::XSBuilder. >> > > > What do you mean by "discuss the template"? The template for the pods you > are talking about above? If you look at the existing 2.0 API docs, I've tried to follow the same layout (i.e. template), but I'm not entirely satisfied with it yet. __________________________________________________________________ Stas Bekman JAm_pH ------> Just Another mod_perl Hacker http://stason.org/ mod_perl Guide ---> http://perl.apache.org mailto:[EMAIL PROTECTED] http://use.perl.org http://apacheweek.com http://modperlbook.org http://apache.org http://ticketmaster.com --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
