URLs with tilde (~) are wrongly flagged

Reported by Christopher Corbettis | June 14th, 2017 @ 11:14 AM

The warning (red) tooltip sometimes shows up with URLs containing tildes (~)

This happens under (as far as I can find) two circumstances:

  1. URL not written up in Markdown.
  2. URL written up in Markdown, with the text part of the Markdown containing a colon.


  • This shows in both the edit window and in the main MailMate window when it’s viewed as a draft.
  • The warning appears in both right and bottom oriented preview layouts.
  • Markdown footnotes are unaffected.
  • I think this is probably due to a mismatch between the URL as typed and the URL encoding of the tilde character.

Steps to reproduce:

  1. Create a new email.
  2. Paste in the following:

    1. [example](http://example.org/~1)
    2. [http://](http://example.org/~2)
    3. [:](http://example.org/~3)
    4. http://example.org/~
    5. http://example.org/~test
    6. example[1]
    [1]: http://example.org/~
  3. If the preview hasn’t automatically appeared, toggle it on.

  4. Hover over each of the URLs in turn, you will notice URLs 2-5 cause a red warning tooltip to appear.
