thispage = hdf.getValue('wiki.page_name', '')

[jon@…]

The AutoNav? plugin is broken with latest svn head. This is because hdf.getValue('wiki.page_name', ) returns an empty string.

Grepping the trac source code, I found references to it in the wiki-macros/TracGuideToc.py file as well.

What should the plugin be calling now to get this information?

What should the plugin be calling now to get this information?

The next wiki refactoring will introduce a "context" information (stacked context, even).

The interface is not yet defined, but it should be something like:

• obtain it from: formatter.context
• this will be a stack of "context" descriptors
• each "context" will at least identify the main resource to which the text being formatted belong (type, detail). We could also think about having the "name" of the text (is it the "page" or the "comment"?) and possibly the module used.

There's already a lot of documented situations where knowing the current context makes sense. There are a few more exotic situations where it's even necessary to know if we are "embedded" in some wider context.

Will you also tell me what I can call right now to fix the plugin?

[cboos]

Well, I don't know about the AutoNav plugin: if it's the "old style" macro, I guess you can't fix it. If it's an IWikiMacroProvider plugin, then the workaround would be to use req.path_info, and strip the /wiki/ prefix if it's there to get the page name (if it's not there, then you have WikiStart, assuming you're wanting to use that macro only in Wiki pages).

(and btw. I suggest that we drop support for the pre-0.9 style of macros in Trac 0.11)

[cmlenz]

This is really important for 0.11. And yeah, we should drop old-style macros… they're pretty much useless when the HDF isn't available anymore anyway.

[anonymous]

It would be great if something like the AutoNav? plugin was included in Trac. I really need that functionality. I'm using AutoNav?3 plugin from your site:

http://trac.edgewall.org/wiki/MacroBazaar

It would be really cool if you just made a mock hdf object available so that all of the old code would just magically work instead of breaking everyone's wiki's when they upgrade.

AutoNav? (new-style plugin)

[stromnov@…]

TracGuideToc (new-style plugin, remove old macro first)

[stromnov@…]

Reimplemented TracGuideToc and AutoNav:

• TracGuideTocPlugin.tar.bz2
• AutoNavPlugin.tar.bz2

[cboos]

Could you rather use .tar.gz or .zip attachments next time? Thanks!

Huh? What's wrong with .tar.bz2? It's a pretty standard format and gives better compression than GZip.

[jon@…]

Tried installing the AutoNav? macro from the above .bz2 and it doesn't seem to work...

The macros attached by stromnov@… are plugins, so you shouldn't copy them to your wiki-macros, where only "old-style" (i.e. pre-0.9) macros are expected. Instead, you should either install them as plugins (see TracPlugins) or simply put the main file in the plugins folder (aka. single file plugins).

And about the .tar.bz2: I'm mainly working on Windows, where that format is not very common and not well supported (e.g. those files can't be opened by the latest Winzip).

I've started to adapt the contributed TracTocGuide?.py a bit further, but I'm not sure yet where to put it... in trac/wiki/macros.py, in contrib?

Suggestions welcomed.

While it is used in preinstalled Trac pages, it is preferably to keep it in trac/wiki/macros.py

[cboos]

Well, perhaps, but at the same time I have the feeling that this macro would be best kept in a file of its own. That's also what I said for the Image macro, some times ago. I wonder if the idea of a trac/wiki/macros folder would be better accepted now ;)

[cboos]

WikiContext implements this.

We should also update the documentation:

• for 0.10 stating that the old-style macros is being phased out and focusing on the documentation for IWikiMacroProvider and WikiMacroBase.
• for 0.11, documenting the interface change in the render_macro method, which will take a Context instead of a Request.

[cboos]

Fixed in r4451. The documentation in this Wiki has been updated as well.

I'll update the AutoNav? macro shortly and put it in the MacroBazaar as an example.

[eblot]

I guess there would be at least a cross-reference to add with th:wiki:MacroMigrationTutorial about macro formats in order to make things easier for macro developers.

Maybe this page should be deprecated on TH to avoid confusion?
