Helm: Select candidates with mouse

[xiongtx]

Expected behavior

In a Helm buffer, it should be possible to move the selection line to a candidate with the mouse (<mouse-1>).

Actual behavior from emacs-helm.sh if possible (See note at bottom)

It is not possible to move the selection line to a candidate with <mouse-1>.

Steps to reproduce (recipe)

N/A

Backtraces if some (M-x toggle-debug-on-error)

N/A

Describe versions of helm, emacs, operating system etc.

• Helm: 2.5.1
• Emacs: 25.1.50.1
• OS: Darwin C02RW05YFVH6 15.6.0

Here how it will behave:

• If helm-prevent-mouse is non-nil, no mouse, same behavior as now.
• helm-prevent-mouse is nil:
  
  
  
  • mouse-1 select candidate
  
  
  • mouse-2 execute default action
  
  
  • mouse-3 popup menu actions
  
  

Perhaps in the future we should also track the mouse for automatic selection
but this is much more work.

This sounds great!

Cool, though I think it's more common for vars to do something when they're non-nil, so I'd reverse helm-prevent-mouse to helm-allow-mouse and make it t by default.

That's a good point. Double-negative options tend to be confusing for some reason.

Yeah, this and some other details I need to fix...

I think I handled now all user cases, let me know when something is wrong.
Should also fix related issue: #501 #1495 and #622.

Still some issues with help-echo's in async-sources that need to be fixed:

• Duplicates in help-echo when redisplaying (helm-locate).
• help-echo at first candidate is overwritten.

Is it just me, or is this significant enough to warrant some kind of announcement or news item? :)

Will add a note in https://github.com/emacs-helm/helm/releases when
releasing next version.

Can I swap mouse2 and mouse3? I haven't owned a mouse with a middle button in 6 years.

Normally, mouse1 + mouse3 == mouse2, IOW press simultenaously your two
mouse button.

I can't do that either, sadly. So far I've bound it to S-.
