Some of the thumbnails in Showcase were out of place
because of several irregularly sized thumbnails,
and some of them almost 300KB in filesize.
Resize them all to 600x400 (pixels), and use the `-tn.png`
suffix.
When necessary, the website snapshot is re-captured using
gnome-web-photo. Then, the following commands (or a combination
thereof) are used to crop and resize the image into a thumbnail,
and to reduce its filesize:
$ convert example.png -crop 900x600+0+0 \
-filter Lanczos2Sharp -distort Resize 600x400 \
example-tn.png
$ pngquant --nofs -v --speed 1 --quality 65-80 example-tn.png
$ optipng -o7 -zm1-9 example-tn-or8.png
$ mv example-tn-or8.png example-tn.png
To prevent "Showcase" from becoming "Showcases",
also to have the RSS feed display correct titles,
i.e. "Showcase on gohugo.io" rather than "Showcase on ".
As Hugo now supports more formats thanks to the new "external helpers"
feature recently introduced, and as requested by some people, I added
some lines in the doc:
* basically confirming it actually exists
* how to use it
'sort' template function used to accept only each element's struct field
name, method name and map key name as its second argument. This extends
it to accept a field/method/key chaining key string like
'Params.foo.bar' as the argument. It evaluates sub elements of each
array or map elements and sorts by them.
Typical use case would be sorting pages by user defined front matter
value. For example, sorting pages by 'Params.foo.bar' is possible by
writing the following template code
{{ range sort .Data.Pages "Params.foo.bar" }}
{{ .Content }}
{{ end }}
It ignores all leading and trailing dots so "Params.foo.bar" can be
written in ".Params.foo.bar"
This also fixes the issue that 'sort' cannot evaluate a pointer value.
Fix#1330
sort template function returns `[]interface{}` type slice value
regardless of its original element type.
This fixes it to keep the original element type. For example, if it
sorts `map[string]int` type value, it returns `[]int` slice value
instead of `[]interface{}` slice value.
When a YAML/TOML's delimiter character sequence is included in a
frontmatter string, parser mistakes it as a delimiter. This fixes it by
checking a character right before the delimiter sequence is '\n' or it
is the beginning of the frontmatter.
Fix#1320
This simplifies the retrieval of the HTML (no more need to extract the
part within body) and also removes the unwanted "Last Updated" part in
the article.
