Added a new Template.PrintErrors() function call,
used in hugolib/site.go#Process() so it does not clutter
up `go test -v ./...` results.
Special thanks to @tatsushid for mapping out the call trace
which makes it a lot easier to find the appropriate places
to place the Template.PrintErrors() call.
Fixes#316
The variable scope in the Go templates makes it hard, if possible at all, to write templates with counter variables or similar state.
This commit fixes that by adding a writable context to Node, backed by a map: Scratch.
This context has three methods, Get, Set and Add. The Add is tailored for counter variables, but can be used for any built-in numeric values or strings.
Use `{{ if not .Date.IsZero }}` to print dates only when they are
defined. This is to avoid things like
<lastBuildDate>Mon, 01 Jan 0001 00:00:00 +0000</lastBuildDate>
and
<lastmod>0001-01-01T00:00:00+00:00</lastmod>
showing up in index.xml (RSS) and sitemap.xml.
Pipe dates with ±hh:mm time zone through `safeHtml`
to prevent the `+` sign from turning into `+`.
Also make some shuffling to avoid blank lines in the output.
* template: _internal/_default/opengraph.html:39: unexpected EOF
* template: _internal/_default/schema.html:15: unexpected {{end}}
Also change the DateTime inside these templates to ISO 8601 format,
and skip <meta itemprop="datePublished"> if `publishdate` is not set.
Perhaps it would be a good idea to expose `func (Time) IsZero`
to our templates? :-)
- Add `safeUrl` template function (Fixes#347)
- Add TestSafeUrl() fashioned after @tatsushid great examples
- Disable `safeHtmlAttr` pending further discussions on its other
use cases because `safeUrl` is a cleaner solution to #347.
(There are also `safeJs` and `safeJsStr` that we could implement
if there are legitimate demands for them.)
- Rename `safeCSS` to `safeCss` (to follow the convention of `safeHtml`)
- Add/expand documentation on `safeHtml`, `safeCss` and `safeUrl`
This allows a template user to keep a safe HTML attribute or CSS string
as is in a template.
This is implementation of @anthonyfok great insight
Fix#784, #347
RSS 2.0 requires the email be listed in `<author>`,
and `UTC` as a timezone is not accepted, but `UT` or `GMT` are.
See #789 for more information. Thanks to @snej for the report!
This changes `echoParam` template function behavior to accept not only
an array or a slice and its index pair but also a map and its key pair.
This also changes the function that float and uint values are treated as
a valid result type of it.
Fix#771
It allows to use `where` template function like SQL `where` clause.
For example,
{{ range where .Data.Pages "Type" "!=" "post" }}
{{ .Content }}
{{ end }}
Now these operators are implemented:
=, ==, eq, !=, <>, ne, >=, ge, >, gt, <=, le, <, lt, in, not in
It also fixes `TestWhere` more readable
'where' 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 dot chaining key like 'Params.foo.bar' as the
argument. It evaluates sub elements of each array elements and checks it
matches the third argument value.
Typical use case would be for filtering Pages by user defined front
matter value. For example, to filter pages which have 'Params.foo.bar'
and its value is 'baz', it is used like
{{ range where .Data.Pages "Params.foo.bar" "baz" }}
{{ .Content }}
{{ end }}
It ignores all leading and trailing dots so it can also be used with
".Params.foo.bar"
The flag `HTML_SMARTYPANTS_ANGLED_QUOTES` was added to Blackfriday on Black Friday. This configures rendering of double quotes as angled left and right quotes («
»).
Typical use cases would be either or, or combined, but never in the same
document. As an example would be a person from Norway; he has a blog in both
English and Norwegian (his native tongue); he would then configure Blackfriday
to use angled quotes for the Norwegian section, but keep them as reqular
double quotes for the English.
This commit adds configuration support for this new flag, configuration that can be set in the site configuration, but overridden in page front matter.
Fixes#605
