Feature Request: Command-click to select and open URL in default browser

Do you mean in the Composer? In that case fn-return should open it. It was buggy on Mojave though and therefore you currently need the latest test release.

You also need “Edit ▸ Substitutions ▸ Smart Links” enabled.

This is very strange; I should have provided an example in my report, because now I have no idea what my problem was. Maybe it was the Composer settings, as you suggest, because I can't find an example in the Viewer in which I can't click on a URL.

Oh, well. If I figure out what I meant, I'll update this ticket, I guess. Sorry about that.

Okay, here we go. This is, in fact, the notification from lighthouse about a change in one of the tickets I submitted. I've included the .emi file, a text dump of the raw message source, and a screen shot of what it looks like in my Viewer. Note that the URL in the message is not highlighted.

This is on my home machine; the machine at work seems to be doing the right thing.

I note also that I'm unable to save the Edit > Substitutions > Smart Links preference; no matter how I enable it, after quitting and relaunching MM, it has turned itself off. There is also no way to enable it unless a Composer window is open, so I don't even know if this option applies to messages in the Viewer.

And, actually, I'm noticing that none of the messages show clickable links in the Viewer on my home machine. I've attached my defaults for MM; any idea what I don't have set correctly?

The setting for smart links does not apply to the viewer. Based on your screenshot we are dealing with “Prefer Plain Text” and therefore the display of a plain text message. Links should appear except if you have this preference disabled:

defaults read com.freron.MailMate MmAutoLinkPlainTextURLsInHTML

As far as I can see you don't use that setting. And I can see no issues with the files you provided.

I'm kind of out of ideas... Maybe check the HTML generated using “Message > Show HTML Source”. See if these links really do not include <a href="...">....</a>.

Well, here's your message:-

What I'm asking for is for MM to detect the https//... string in the text and highlight it so that I can click on it, whether or not it's part of an tag or even part of the HTML section of a message. The ability to click a link should be available even in plain text messages.

But I guess you're saying is that MM should be doing that already, unless I have MmAutoLinkPlainTextURLsInHTML set to False, which I don't (in fact, I explicitly just set it to True and quit and relaunched MM, and it made no difference).

That is correct. It should work by default. But MailMate is clearly involved since links are not generated in the output you see above.

There's a primitive debug variable which we can also use to check the HTML generated:

defaults write com.freron.MailMate MmDumpGeneratedHTML -bool YES

Then launch from a Terminal window:

/Applications/MailMate.app/Contents/MacOS/MailMate

This is just to make absolutely sure that nothing is generated. (I'll need to add more debug output to MailMate to see if MailMate tries to generate links at all.)

I'm attaching the output from a run using your debugging option.

Whoops. That didn't work. Here it is.
