What's the output of :echo has('float')?

[frace]

:echo has('float')
1

vim --version | ag float
-balloon_eval    +float           +mouse_urxvt     -tag_any_white

Hmm, I have no idea why it fails, how about this expression?

:let a = 0.5 | echo a * 2

[frace]

Your expression gives me the same result. That's really strange. I just found out there's another plugin (sunset) suffering from this problem, too.

:let a = 0.5 | echo a * 2
E806: using Float as a String
E15: Invalid expression: 0.5 | echo a * 2

So I'd say the problem is somewhere else but not in your plugin...

It's a bug of Vim you have, and I remembered that I had the same issue before:
junegunn/vim-easy-align#27

So I applied the same workaround to Limelight, it should help.

Thank you for the quick fix! It works now.
I searched for the bug but it seems like reports are from around 2009-2011 - and there had been fixes for it. Strange that it bites me right now. :)

I just wanted to let you know that I hit the bug again while declaring

let g:limelight_default_coefficient = 0.7

I assume there is another location in limelight.vim where it is necessary to call str2float().

Since it is closely related I refrained from opening a new issue.

[Junegunn Choi]

let g:limelight_default_coefficient = str2float('0.7')

[frace]

Or so - Should be sufficient as a temporary solution. Thank you for the enlightenment. :)
