如何在文件范围内跳过一个特定的文件名

Question

I'm working on some blog code (written by someone else) which lists all posts into the main index.html file. I want to exclude one file (welcome.md) from this listing. I believe this is the relevant code that does this -

{{$l := len .}}
{{range $i, $e := .}}         
<h3><a href="/{{$e.Title | slug}}.html">{{$e.Title}}</a></h3>

Is it possible?

Update - Here is my full code, I left some out of the above -

{{define "title"}}
  Test
{{end}}

{{define "content"}}
<h1>Heading</h1>

{{$l := len .}}
      {{range $i, $e := .}}
      {{- if ne $e.Title "welcome" -}}        
            <h3><a href="/{{$e.Title | slug}}.html">{{$e.Title}}</a></h3>
            {{- end }}
            <small>
              <em>
              {{$e.Written.Format "Jan 2, 2006"}}&nbsp;
              Tags:  {{range $e.Tags}}
              <a href="/tags/{{. | slug}}.html" title="Posts Tagged {{.}}">{{.}}</a>&nbsp;
                {{end}}
              </em>
            </small>
            {{(printf "%s </br><small>[Read more](/%s.html)</small>" ($e.Content | summary) (.Title | slug)) | html}}

{{end}}
{{end}}

You can use {{if ...}} in templates. Combine with the ne function (for "not equal"):

{{range $i, $e := .}}
  {{- if ne $e.Title "welcome" -}}
<h3><a href="/{{$e.Title}}.html">{{$e.Title}}</a></h3>
  {{- end }}
{{ end }}

However, it feels like maybe you can make it more general purpose if you have control over the data model. Perhaps a flag on each post for ExcludeFromIndex or something like that:

{{- if !$e.ExcludeFromIndex -}}

That way if you add more "special" pages you won't need to keep adding if statements for each one. Just an idea.
