htmlformat

htmlformat is a Go package and CLI tool used to format HTML.

It is forked and simplified from the https://github.com/ericchiang/pup package.

It does not aim to:


Colorize output.
Modify the input HTML except for formatting (i.e. no HTML escaping will be applied).
Provide any facilities to query the content.


Installation

To use the CLI, you can install with Go > 1.20.

go install alin.ovh/htmlformat/cmd/htmlformat@latest


Usage

CLI

echo '<ol><li style="&"><em>A</em></li><li>B</li></ol>' | htmlformat
<ol>
 <li style="&">
  <em>A</em>
 </li>
 <li>B</li>
</ol>


Package

r := strings.NewReader(`<ol><li style="&">A</li><li>B</li></ol>`)
w := os.Stdout
if err := Fragment(w, r); err != nil {
  log.Fatalf("failed to format: %v", err)
}
