Plug-In: Transform Links

(IMPORTANT: This plug-in requires OmniFocus 4.x)

A pair of plug-ins for transforming links in the note of the selected project or task:

• Replace Markdown Links • This plug-in will replace all occurrences of links in markdown format [Link-Title](Link-URL-String) with link objects.
• Replace Links with Markdown • This plug-in converts all occurrences of link objects into text in markdown link format: [Link-Title](Link-URL-String)

NOTE: The current versions of the plug-ins have been updated to fix an erroneous application version check.

IMPORTANT: Do no run the following plug-in (“Replace Link Objects with Markdown”) if the note currently contains links in markdown format: [LINK NAME](LINK URL). Instead, first convert the “markdown links” to “link objects” using the “Replace Markdown Links” plug-in, then run the the following plug-in (“Replace Link Objects with Markdown”).
