PatternFly Elements Code Block

<pfe-code-block> is a component that contains two or more lines of ready-only code. The code in a code block can be copied to the clipboard.

Read more about Code Block in the PatternFly Elements Code Block documentation

Installation

Load <pfe-code-block> via CDN:

<script src="https://unpkg.com/@patternfly/pfe-code-block?module"></script>

Or, if you are using NPM, install it

npm install @patternfly/pfe-code-block

Then once installed, import it to your application:

import '@patternfly/pfe-code-block';

Usage

Basic

Place your code in a script tag with a [non-javascript mimetype][mime]. JavaScript snippets must use the text/javascript-sample script type. Script text content will be automatically dedented.

To add copy-to-clipboard functionality, be sure to import @patternfly/pfe-clipboard and add the pfe-clipboard to the action slot.

<pfe-code-block>
  <script type="application/openshift">
    apiVersion: helm.openshift.io/v1beta1/
    kind: HelmChartRepository
    metadata:
    name: azure-sample-repo0oooo00ooo
    spec:
    connectionConfig:
    url: https://raw.githubusercontent.com/Azure-Samples/helm-charts/master/docs
  </script>
</pfe-code-block>

Expandable

If a block of code is long and you'd like to hide some of the code to take up less height on the page, place the code you'd like to hide in a script with data-expand attribute present.

It is important that you place the span right next to the first script, because of how the whitespace will be handled. Failing to do this can result in unwanted line breaks.

<pfe-code-block id="expandable-code">
  <script type="application/openshift">
    apiVersion: helm.openshift.io/v1beta1/
    kind: HelmChartRepository
    metadata:
    name: azure-sample-repo</script><script type="application/openshift" 
    data-expand>
    spec:
    connectionConfig:
    url: https://raw.githubusercontent.com/Azure-Samples/helm-charts/master/docs
  </script>
  <pfe-clipboard slot="actions" copy-from="#expandable-code"></pfe-clipboard>
</pfe-code-block>
