## Traversing Local Files
|
|
|
|
Hugo includes a way to traverse local files.
|
|
This is done using the 'readDir' function.
|
|
|
|
## Using readDir
|
|
|
|
readDir takes a single string input that is relative to the root directory of the site. It returns an array of [os.FileInfo](https://golang.org/pkg/os/#FileInfo)
|
|
|
|
Let's create a shortcode to build a file index with links using readDir.
|
|
|
|
'fileindex.html'
|
|
|
|
<table style="width=100%">
|
|
<th>Size in bytes</th>
|
|
<th>Name</th>
|
|
{{$dir := .Get "dir"}}
|
|
{{ $url := .Get "baseurl" }}
|
|
|
|
{{ $files := readDir $dir }}
|
|
{{ range $files }}
|
|
<tr>
|
|
<td>{{.Size}}</td>
|
|
<td>
|
|
<a href="{{$url}}{{.Name | urlize }}"> {{.Name}}</a>
|
|
</td>
|
|
</tr>
|
|
{{ end }}
|
|
</table>
|
|
|
|
Now lets use it to list the css files used on this site
|
|
|
|
{{</* fileindex dir="static/css" baseurl="/css/" */>}}
|
|
|
|
Is rendered as:
|
|
|
|
{{< fileindex dir="static/css/" baseurl="/css/">}}
|
