NewFeatures/MacroTextFormatting

New: Text formatting via macros

I (ChrisSiebenmann) found myself with a genuine need for text set in HTML <strike>. Rather than try to invent a formatting setup for this that did not make me cringe, I just punted to the easy solution: macros that do text formatting.

So, DWiki now has grown the new macros:

ST for the font styles DWiki didn't already have.
C for character entities, and ShowCharEnts to show the named entities we support.
because I was there anyways, AB for <abbr>, so I could have those cute inline abbreviation expansion things. Tragically <abbr> is not supported by IE 6 and less, so AB may quietly change to generating <acronym> someday.
and finally, IMG to generate <img>. Width, height, and alt text is mandatory, and there is a hacky way to also roll title text in too. (Title text is optional.)

Through special black magic, ST, C, and AB can be used in comments (the omission of IMG is deliberate). In theory this lets a commenter cause character set explosions, but in practice a bad commenter can just write UTF-8 directly (UTF-8 is the common and only sane character set choice, so).

Implementing these as macros means that they have some limitations. You can't nest C, AB, or a differently styled ST inside an ST, and currently none of them can be done inside link text ([[....]]).

These macros are a bit of a hack. It's relatively easy to implement bits of HTML this way, but I'm not sure if it's good design overall.

CharacterEntities, 02:17:06 by cks

Character entity names recognized by DWiki

This is the automatically generated big list of character entities recognized by (this) DWiki in the C macro. For the meanings and more precise specifications of these, see the Character entity references in HTML 4 from the HTML 4.01 specification.

Note that not everything in this list may show as a character in your browser, or in other people's browsers. Also, this list is pretty much the full HTML 4.01 list. Older versions of HTML don't define all of these entities; the Wikipedia page is the best reference for what entities are defined in what version of HTML. (Since DWiki doesn't know what HTML version you're labelling its output as, it can't restrict the entities C will accept.)

Some tedious but possibly important detail: DWiki takes its list of known character entities from the Python htmlentitydefs module.

NewFeatures/PrevNextLinks

New: Previous and Next links in pages in blog views

The more I have used DWiki for a blog, the more I've realized that I want individual entries to be able to have Previous (entry) and Next (entry) links. At first I resisted because this would require an expensive filesystem walk on even individual page views, but I have now given in and made the blog::prevnext renderer, which will do this if I want.

blog::prevnext generates links directly to the pages, not to /range/N-N/ virtual directories, because I think that works better. (It would be less code the other way, but better links are worth the code.)
