Hugo escaping + char

Mooash · May 20, 2020, 6:32am

I think this is something to do with my local setup but I can’t get hugo to stop escaping the + char in HTML.

Even a minimal example taken from Hugo’s website theme:

gohugoio/gohugoioTheme/blob/0095b7b902a74c4c98a09641d81a473673036692/layouts/_default/baseof.html#L24-L26


{{ range .AlternativeOutputFormats -}}
<link rel="{{ .Rel }}" type="{{ .MediaType.Type }}" href="{{ .Permalink | safeURL }}">
{{ end -}}

Results in it being escaped:

<link rel="alternate" type="application/rss&#43;xml" href="http://example.org/index.xml">

Exact same when printing just {{ .Lastmod }} for example, + is escaped.

<meta property=article:modified_time content="{{ .Lastmod }}">

Results in (bad time due to page not having a modified time):

<meta property=article:modified_time content="0001-01-01 00:00:00 &#43;0000 UTC">

Any way to prevent + being escaped? I’ve tried multiple different varieties of safeHTML, htmlUnescape etc but can’t get it to print normally.

Steps to replicate:

Setup minimal hugo website (eg hugo new site .)

Add below snippet or anything that prints the + char

{{ range .AlternativeOutputFormats -}}
<link rel="{{ .Rel }}" type="{{ .MediaType.Type }}" href="{{ .Permalink | safeURL }}">
{{ end -}}

Build website and see that char is escaped

This is the example from Hugo internal opengraph template:

<meta property="og:image" content="{{ index . 0 | absURL }}"/>
{{ end }}{{ end }}{{ end }}

{{- $iso8601 := "2006-01-02T15:04:05-07:00" -}}
{{- if .IsPage }}
{{- if not .PublishDate.IsZero }}<meta property="article:published_time" {{ .PublishDate.Format $iso8601 | printf "content=%q" | safeHTMLAttr }} />
{{ else if not .Date.IsZero }}<meta property="article:published_time" {{ .Date.Format $iso8601 | printf "content=%q" | safeHTMLAttr }} />
{{ end }}
{{- if not .Lastmod.IsZero }}<meta property="article:modified_time" {{ .Lastmod.Format $iso8601 | printf "content=%q" | safeHTMLAttr }} />{{ end }}
{{- else }}
{{- if not .Date.IsZero }}<meta property="og:updated_time" {{ .Lastmod.Format $iso8601 | printf "content=%q" | safeHTMLAttr }} />
{{- end }}
{{- end }}{{/* .IsPage */}}

{{- with .Params.audio }}<meta property="og:audio" content="{{ . }}" />{{ end }}
{{- with .Params.locale }}<meta property="og:locale" content="{{ . }}" />{{ end }}
{{- with .Site.Params.title }}<meta property="og:site_name" content="{{ . }}" />{{ end }}
{{- with .Params.videos }}
{{- range . }}
<meta property="og:video" content="{{ . | absURL }}" />
{{ end }}{{ end }}
