Wahlberg

A Markdown field with a GitHub-style editor.

A Write tab, a Preview tab, a formatting toolbar, and admin-defined snippets.

🚧 Wahlberg is in beta. The templating surface, |marky filter, wahlberg_Markdown GraphQL type, Editor::inputHtml() options, both events, and the config/wahlberg.php snippet format are settled. The field’s own settings may still move.

• Raw Markdown in, raw Markdown out
• Server-side preview, parsed with the same parser as Craft’s |md filter
• HTML Purifier on the parsed output by default
• Craft reference tags resolved on output and left alone inside code, and written by the entry and asset pickers, so links survive a slug change or a replaced file
• Markdown syntax highlighting in the Write tab without giving up the plain textarea, and a band behind the line being written
• Formatting toolbar of headings, bold, italic, strikethrough, quote, code, link, element pickers and lists, folding into a menu when the field is too narrow. Or a floating one, in a panel over the selection
• / at the caret opens an insert menu of the element pickers and your snippets, filtered as you type
• Snippets you define in config, with tab stops and defaults
• ⌘B / ⌘I / ⌘K, ⌘⇧E and ⌘⇧U for the pickers, ⌘⇧K for snippets, ⌘⇧P to preview, ⌘⇧F for the floating toolbar
• Buttons toggle, Enter carries on a list, and native browser undo survives
• The editor grows to fit what’s typed, sticks its header on a tall field, and keeps your place across the tabs
• No editor library bundled: a textarea, some vanilla JS, and Craft’s own icons
• Per-field flavour, toolbar, line length, sizing, limits and counts
• GraphQL support
• Reusable outside the field type, from Twig or PHP
