    Universal markup converter

    Project mention: Why we have only option for Cloud storage on PrivacyGuide website? | reddit.com/r/PrivacyGuides | 2023-03-20

    For notes, thoughts and the like, I use Joplin with e2ee enabled. Over the years, I find myself using it for thing I would have previously opened up a google doc for. With Joplin you can go far beyond the basic markdown features of Github flavored markdown to make it a really useful, dynamic document. Then it is a simple 1 line of text in your terminal (using pandoc) to convert that to a *.docx file. I find I'm much more productive using markdown than I am using a rich text editor.

These include Signal and WhatsApp (both owned by Facebook), as well as Telegram and Wire (owned by Google). These services use end-to-end encryption, so they don't store any data on their servers or share it with anyone else.

    I think the corresponding HLS PR is https://github.com/haskell/haskell-language-server/pull/3462, so it isn't landed yet but hopefully can be part of a HLS release before too long. (I'm not sure if it will make it in to the very next release because we're due one out to support GHC 9.6.1 pretty soon.)
