Error with mermaid-open-browser about mermaid-mode HOT 7 CLOSED

Thank you for your interest!
That is very weird. I am also on emacs 26.1 and I see browse-url-default-browser defined in browse-url.el which is part of the regular codebase?
What happens if you do a C-h f browse-url-default-browser? do you see the function defined?

from mermaid-mode.

@abrochard I don't have that function defined... And I have browse-url.el installed.

As I said in the OP, I'm using Ubuntu 19.04. Maybe something is different in Ubuntu from your distro.

So weird. That would be an interesting thing to ask on a forum or something.

As a workaround, I propose you define the function yourself?

You could stick that guy into your config?

How about using browse-url-xdg-open instead of browse-url-default-browser? Doesn't that work?

from mermaid-mode.

Closed by mistake... sorry...

Fixed it!

Was using use-package to pull mermaid-mode. Had to (require 'browse-url) in package initialization. Seems to be working fine now.

Thanks!

Awesome! Thank you! I wonder if I should add that require in the package....
