Hello, I’ve mounted static directory in order to get access to some resources in `hugo.toml` like this:

```auto
  [[module.mounts]]
    source = 'static'
    target = 'assets'

```

I can’t get readFile function to work in a snippet:

```auto
{{< code source="static/examples/bas_con_sin.txt" language="go" >}}

```

Which is:

```auto
start
{{ $language := .Get "language" }}
{{ $source := .Get "source" }}
{{ $options := .Get "options" }}

{{ with $source | readFile }}
{{ highlight (trim . "\n") $language $options }}
{{ end }}
end

```

How its look like:

Here is my sources:

Have I did something wrong with the config?

the mount has nothing to do with `readFile`. _readFile_ only sees your “real” filesystem not the virtual one.

- `static/examples/bas_con_sin.txt` will work

Code defensive and check the result of `readFile` (same for $language)

```auto
{{ with $source | readFile }}
  {{ highlight (trim . "\n") $language $options }}
{{ else }}
  {{ errorf "could not readFile: %s" $source }}
{{ end }}

```

### Now to your problem:

you wrapped the call to your shortcode within another one.

Use the `{{< expand >}}` syntax instead of {{% %}}

```auto
{{< expand title="Full example" >}}
{{< code source="examples/bas_con_sin.txt" >}}
{{% /expand %}}

```

#### TL;TR

There’s a difference when calling shortcodes using `{{%` or `{{<`

- The inner `{{< code ...` will return plain HTML (the highlighted content)
- The outer `{{% expand ...` will receive that as input and try to render it as Markdown

Since rendering HTML in Markdown is turned off by default in hugo see [unsafe](https://gohugo.io/getting-started/configuration-markup/#rendererunsafe)

The highlighting result is replaced with “” (check it your public folder)

Thanks a lot for this.  
I guess I should re-read the documentation next time I want to ask a question.

There’s a long story here, but I would strongly recommend that you use Hugo’s Resource abstraction instead of the readFile function, e.g.

- Mount some folder into /assets
- Use resources.Get etc.

Hi @sedyh.

As you most likely are fiddling around with the Relearn theme, you could just try

````auto
```go
{{% include "examples/bas_con_sin.txt" %}}
```

````

or with expand

````auto
{{% expand title="Full example" %}}
```go
{{% include "examples/bas_con_sin.txt" %}}
```
{{% /expand %}}

````

This will save you from writing your own `code` shortcode.

Oh, cool, I didn’t expect that.  
In fact, I need not just a code listing, but an insertion of several snippets by id from the same file.

I think I should make a separate topic for this…

> Hello, I want to make a shortcode which allows me to paste multiple snippets from single file by their id. I.e.
