Simple ioutil.ReadFile is used for reading file contents but it reads
all of the file contents and copies them into the memory and is run in a
single goroutine. It causes much memory consumption at copying media
files in content directory to publish directory and it is not good at
performance.
This improves the both issue by replacing ReadFile with LazyFileReader.
It postpones reading the file contents until it is really needed. As the
result, actual file read is run in parallelized goroutine. It improves
performance especially in a really big site.
In addition, if this reader is called from io.Copy, it does not copy the
file contents into the memory but just copies them into destination
file. It improves much memory consumption issue when the site has many
media files.
Fix#1181
LazyFileReader is an io.Reader implementation to postpone reading the
file contents until it is really needed. It is introduced for improving
performance and memory consumption at reading media files in content
directory.
As of 2015-08-16, Viper no longer searches the CWD
for config file by default to avoid unintended surprises,
but Hugo relies on the original behaviour.
Fixed by calling
viper.AddConfigPath(".")
at the appropriate place.
See https://github.com/spf13/viper/issues/73 for more information.
Fixes#1363
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
