+date.

-For the _search.html_ template only:
+_{{.Today}}_ is the current date, in ISO format. This is useful for "new page"
+like links or forms (see *EXAMPLE* below).
+
+_{{.Diff}}_ is the page diff for _diff.html_. It is only computed on demand so
+it can be used in other templates, too. It probably doesn't make much sense to
+do so, however.
+
+## Feed
+
+The feed contains an item for the head of the feed and an array of items.
+
+_{{.Items}}_ is the array of feed items. To refer to them, you need to use a
+_{{range .Items}}_ … _{{end}}_ construct.
+
+If page A links to pages B and C, the head of the feed is based on page A and
+the list of items contains B and C.
+
+An item is a page plus a date. All the properties of a page can be used (see
+*Page* above).
+
+_{{.Date}}_ is the date of the last update to the page, in RFC 822 format.
+
+## Search
+
+_{{.Query}}_ is the query string.
+
+_{{.Dir}}_ is the directory in which the search starts, percent-escaped except
+for the slashes.
+
+_{{.Items}}_ is an array of pages (see *Page* above). To refer to them, you need
+to use a _{{range .Items}}_ … _{{end}}_ construct.

 _{{.Previous}}_, _{{.Page}}_ and _{{.Next}}_ are the previous, current and next
 page number in the results since doing arithmetics in templates is hard. The
-first page number is 1. The last page is expensive to dermine and so that isn't
-done.
+first page number is 1. The last page is expensive to dermine and so that is not
+available.

 _{{.More}}_ indicates if there are any more search results.

 _{{.Results}}_ indicates if there were any search results at all.

-_{{.Items}}_ is an array of pages, each containing a search result. A search
-result is a page (with the properties seen above). Thus, to refer to them, you
-need to use a _{{range .Items}}_ … _{{end}}_ construct.
+## Upload

-For items in the search result:
+_{{.Dir}}_ is the directory where the uploaded file ends up, based on the URL
+path, percent-escaped except for the slashes.

-_{{.Html}}_ is the rendered Markdown of a page summary, as HTML.
+_{{.Name}}_ is the _filename_ query parameter.

-_{{.Score}}_ is a numerical score for search results.
+_{{.Last}}_ is the filename of the last image uploaded.

-For the _feed.html_ template:
+_{{.Image}}_ is a boolean to indicate whether the last file uploaded has a file
+name indicating an image or not (such as ending in _.jpg_). If so, a thumbnail
+can be shown by the template, for example.

-_{{.Name}}_ is the page name, escaped for use in URLs.
+_{{.MaxWidth}}_ is the _maxwidth_ query parameter, i.e. the value used for the
+previous image uploaded.

-_{{.Title}}_ is the title of the underlying main page.
+_{{.Quality}}_ is the _quality_ query parameter, i.e. the value used for the
+previous image uploaded.

-_{{.Date}}_ is the date of the last update to the underlying main page, in RFC
-822 format.
-
-_{{.Items}}_ is an array of feed items.
-
-For items in the feed:
-
-_{{.Name}}_ is the page name, escaped for use in URLs.
-
-_{{.Title}}_ is the title of the page.
-
-_{{.Html}}_ is the rendered Markdown, as escaped (!) HTML.
-
-_{{.Hashtags}}_ is an array of strings.
-
-_{{.Date}}_, the date of the last update to this page, in RFC 822 format.
-
-The _upload.html_ template cannot refer to anything.
+_{{.Today}}_ is the current date, in ISO format.

+# Alex Schroeder theme
+
+At the top there's a text input to quickly create new pages.
+
+This theme comes with an external CSS file. If you plan to use
+subdirectories for your site, you need to change the URL of the CSS in
+the HTML templates to `/view/oddmu.css` or serve it as a static file
+from a `/css` directory.
+
+The CSS switches between light and dark mode based on the visitor's
+setup.

+# Campaign Wiki theme
+
+A beige theme that sticks close to the default. This site treats every
+subdirectory as its own wiki and so there's a "Changes" link to the
+local changes files and a "Zip" link to download the current
+directory. This is so people can download a backup of their data.
+
+On the real site, the link to the zip file on the top level is
+unavailable because of a redirect so that people download only their
+own wikis and not all the wikis, for bandwidth reasons. This is part
+of the Apache config, however.
+
+(Back up to the [list of themes](../index).)

+        Picture metadata is only removed if the pictures gets resized.
+        Providing a new max width is recommended for all pictures.
+        If you're uploading multiple files, they are all renamed using the filename above and therefore they all get the same extension so they must be of the same type.

Alex Schroeder	acac745e1f	Rewrite staticCmd to use a lot of go routines Starting a go routine that walks the directory tree, adding files to a tasks channel and then closing it; starting a bunch of worker go routines that take files from the tasks channel until there is nothing left to do; putting errors on a results channel and when they’re done, putting a true value on a done channel; a watcher go routine that checks the done channel and if every worker is done, close the results channel; and the main program goes through all the values on the results channel and sets up some short-circuiting in the case of errors and otherwise it prints the counter.
