Overall, I believe your critique is - >> well-founded, I'll scratch this patch. +I rearranged my patchset once again, to clearly identify the origin and +motivation of each patch, which is explained in the following. + +In my ikiwiki-based website I have the following situation: + +* `$config{usedirs}` is 1 +* there are a number of subdirectories (A/, B/, C/, etc) + with pages under each of them (A/page1, A/page2, B/page3, etc) +* 'index pages' for each subdirectory: A.mdwn, B.mdwn, C.mdwn; + these are rather barebone, only contain an inline directive for their + respective subpages and become A/index.html, etc +* there is also the main index.mdwn, which inlines A.mdwn, B.mdwn, C.mdwn, + etc (i.e. the top-level index files are also inlined on the homepage) + +With the upstream `inline` plugin, the feeds for A, B, C etc are located +in `A/index.atom`, `B/index.atom`, etc; their title is the wiki name and +their main link goes to the wiki homepage rather than to their +respective subdir (e.g. I would expect `A/index.atom` to have a link to +`http://website/A` but it actually points to `http://website/`). + +This is due to them being generated from the main index page, and is +fixed by the first patch: ‘inline: base feed urls on included page +name’. As explained in the commit message for the patch itself, this is +a ‘forgotten part’ from a previous page vs destpage fix which has +already been included upstream. + +The second patch, ‘inline: improve feed title and description +management’, aligns feed title and description management by introducing +a `title` option to complement `description`, and by basing the +description on the page description if the entry is missing. If no +description is provided by either the directive parameter or the page +metadata, we use a user-configurable default based on both the page +title and wiki name rather than hard-coding the wiki name as description. + +The third patch, ‘inline: allow assigning an id to postform/feedlink’, +does just that. I don't currently use it, but it can be particularly +useful in the postform case for example for scriptable management of +multiple postforms in the same page. + +In one of my wiki setups I had a terminating '/' in `$config{url}`. You +mention that it should not be present, but I have not seen this +requirement described anywhere. Rather than restricting the user input, +I propose a patch that prevents double slashes from appearing in links +created by `urlto()` by fixing the routine itself. + +The inline plugin is also updated (in a separate patch) to use `urlto()` +rather than hand-coding the feed urls. You might want to keep this +change even if you discard the urlto patch. |
