What is the semicolumn in the console?

Hi,

Sometimes, when I load the code to esp8266, there is ":" prompt waiting for input and nothing (like Enter) cancels it.

What is that?

Mismatched parens/braces?

I think that's the prompt it shows when a function/etc has been continued onto the next line because there's an open paren/etc?

Try Ctrl + C to cancel it.

How are you loading code up? If you're using the right-hand side and clicking 'upload' then it shouldn't happen.

The : happens when you have entered a multi-line command, which you do my having more open brackets than close brackets.

So if you type:

function a() {}

Then you get back to >

But if you type the following:

>function a() {
:

Then you have one open bracket and you get the : (as shown)

To end the function, just add a closing bracket and hit enter:

>function a() {
:}
=function () {}
> 

Of course if that doesn't work, it might be because you have more than one open bracket :)

Note that if you're sending code from the right hand side of the IDE, instead of copy/pasting into the left side, the minifier will complain if you have missing braces or other syntax errors.
