Concatenate variable in Hugo

support
1

With,

[Params]
contentCommitsURL = https://api.github.com/repos/csitauthority/CSITauthority.github.io/commits?path=HUGO/content/

the following snippet works wonderfully, on hugo, to generate a Link to API call from a post layout

 {{ if and (or .IsPage .IsSection) .Site.Params.contentCommitsURL }}
                  {{ $File := .File }}
                  {{ $Site := .Site }}
                  {{with $File.Path }}
                  <a href="{{ $Site.Params.contentCommitsURL }}{{ replace $File.Dir "\\" "/" }}{{ $File.LogicalName }}" target="blank">Link to API call</a>
                  {{ end }}
                {{ end }}

Problem Description

The url is generated but I’m pulling hairs trying to figure out how to save the result in a variable.

I want to be able to do something like this:

{{ $url := $Site.Params.contentCommitsURL + (replace $File.Dir "\\" "/") + $File.LogicalName }}

so that I can later access {{ $url }} and use as desired. Perhaps like <a href="{{$url}}">Link to API call</a> . Or, for other purposes like {{ range getJSON $url }}

I think print is what you’re looking for

as a generalish example:

{{$base := $.Param "contentCommitsURL"}}
{{$foo := "bar"}}
{{$url := print $base "/" $foo}}

I was able to solve that issue nicely as follows:

{{ if and (or .IsPage .IsSection) .Site.Params.contentCommitsURL }}
      {{ $File := .File }}
      {{ $Site := .Site }}
      {{with $File.Path }}
      {{ $fileDir := replace $File.Dir "\\" "/"}}
      	{{ $url := $File.LogicalName | printf "%s%s" $fileDir | printf "%s%s" $Site.Params.contentCommitsURL }}
      	{{ $.Scratch.Set "url" $url }}
      {{ end }}
  	{{ end }}

Then, where I want the page contributors to appear

{{ $url := $.Scratch.Get "url"}}
  {{ range getJSON $url }}
    <div style="display:inline-block; width:40px;"><a href="{{.author.html_url}}" target="_blank">
    <img src="{{.author.avatar_url}}" alt="{{.author.login}}" text="{{.author.login}}" class="inline" width="40" height="40" style="height: 40px;height: 40px; vertical-align:middle; margin: 0 auto;"></a>
  </div>
  {{ end }}

But alas, the human mind is never satisfied…

To make this perfect, I would like to know how I can filter distinct {{ .author.login }} . I am getting same authors being returned multiple times *
( * = equal to the number of times that the author has committed to that particular file.)

An example would be: this returns siddhantrimal twice!

I need it to return once. If multiple authors, I need to list each distinct author.
