Add string.nonBlank

[leaumar]

fixes #226

Useful for all kinds of user/file/env sourced inputs that may contain strings of whitespace where a meaningful value is expected.

[sindresorhus]

I think this could be written more clearly.

I tried to run the tests, but...

PS D:\Projects\ow> npm test

ow@0.28.1 test
xo && c8 ava

Alright, if the last open point (making the wording clearer) is solved for you, I have no remaining points other than not being able to run the tests.

Found a list of metachars in js, turns out there are only 6 so I figured I'd add them to stop at a logical point. \f and \v aren't so common but I can imagine \0 popping up in places. Had to write \0 as \x00 because my IDE thinks it's an error otherwise, even though it works fine in a js console.

CI is failing

[leaumar]

Try it now?

[leaumar]

Oh, yeah, a null byte wouldn't actually be whitespace. I'll remove that, then it should be good.

[sindresorhus]

@leaumar We unfortunately cannot release this until TS supports ESM, but in the meantime, you can install this with npm i 'sindresorhus/ow#96207f00f3b3ab8b79e258f892ec948731a8cfd4'.

Sounds like something that could take months still, if ever?

[sindresorhus]

It will be in TS 4.6 (was supposed to be in this release, but pulled last minute). So probably a month or two. TS 4.5 is scheduled to be out today.

[leaumar]

Ah, cool. Thanks for the pointer

This is finally out: https://github.com/sindresorhus/ow/releases/tag/v1.0.0
