Regex not respected in 'getWordRangeAtPosition'

[franciscorubin]

I am having issues with the method 'getWordRangeAtPostition' of TextDocument. The problem is that the regex added as second argument is not respected.

This is my code:
const wordRange = editor.document.getWordRangeAtPosition(selection.active, /[a-zA-Z0-9_[[:space:]]]*/);

Using this example:

"bla bla bla bla"

To my understanding, the four words should be selected, as the [[:space:]] regex indicates that spaces are part of words. But the behaviour is the same than without the regex (only 1 word is selected).

Does it work with a space literal instead of the space character class?

@roblourens
Same thing :(

Using regex: /[a-zA-Z0-9_ ]*/

The problem is that the regular expression matches the empty string which very likely causes endless loops when trying to go from word to word. Therefore it is ignored. I will update the docs and emit a warning when this happens
