Thanks to danielbeck, the part I was missing was to use the codemirror-mode:
<f:textarea name="parameter.description"
value="${instance.description}"
codemirror-mode="${app.markupFormatter.codeMirrorMode}"
codemirror-config="${app.markupFormatter.codeMirrorConfig}"
previewEndpoint="/markupFormatter/previewDescription" />I have made it part of the following pull request: https://github.com/jenkinsci/validating-string-parameter-plugin/pull/3 -- You received this message because you are subscribed to the Google Groups "Jenkins Developers" group.
