Uncaught TypeError: Cannot read property 'Symbol(Symbol.iterator)' of filter.match

setalosas commented 6 years ago

[Enter steps to reproduce:]

This error came up after I added the line filter: hue-rotate(-151deg) saturate(90%); to the Atom style.less file. I have other filter with just one parameter for a while, it doesn't make any trouble, only the double one. I stepped into the code:

When I step through this line, I get the error detailed below.

Effect: after I close the error message, I can continue editing.

Atom: 1.30.0-beta2 x64 Electron: 2.0.5 OS: Microsoft Windows 10 Pro Thrown From: minimap package 4.29.8

I created this issue from Atom, clicking on 'Create issue' in the error form.

Let me know if you have any further questions.

We don't support the bugs thrown when you edit the package manually. Sorry.

setalosas commented 3 years ago

Of course I did not edit the package manually. I edited the styles.less of Atom, which I consider acceptable behaviour.

The bug is in the dom-styles-reader.js file and it still exists after these years:

const hueRegexp = /hue-rotate\((\d+)deg\)/

This should be:

const hueRegexp = /hue-rotate\((-?\d+)deg\)/

(The actual version cannot read negative hue values.)

Could you make a pull request with your suggested fix?
