"*" not valid for any if used as second match, and result confusion

[Portur]

Im sure im doing this right.... but my tests result in the following

const domainMatch = require('wildcard');

domainMatch ( '4' , [ '*' ] ).length                        //-> 0    //1 expected
domainMatch ( '4000' , [ '*' , 'somethingelse' ] ).length   //-> 0    //1 expected
domainMatch ( 'localhost' , ['*'] ).length                  //-> 0    //1 expected
domainMatch ( 'localhost' , [ 'localhost' ] ).length        //-> 1    //1 expected
domainMatch ( '*' , [ '*' ] ).length                        //-> 1    //1 expected

so, according to the doc

domainMatch ( 'a.b.*', [ 'a.b.c', 'a.b', 'a', 'a.b.d' ]).length   //->3  //3 expected
//but
domainMatch ( '*.*.*', [ 'a.b.c', 'a.b', 'a', 'a.b.d' ]).length  //->4  //4 expected
domainMatch ( 'a.b.c, a.b, a, a.b.d', '*.*.*')                  //false //true expected

Summary
which is then where the confusion is. the first item is matched against the second, however the second being '*' will not match.

domainMatch ('localhost', [ '*' ]).length //->0  //1 expected
domainMatch ('*', [ 'localhost' ]).length //->1  //1 expected

also

domainMatch( '*, localhost ', 'localhost' )       //-> false      //true expected
domainMatch( '*', 'localhost' )                   //-> Array[1]   //true expected

I understand the issue is more matching the first to the rest. Building this example also helped me clear it up but I just wanted to let you know my thoughts.

The first item needs to be a string array and the second a string, however the second should be of type Array and the second string, but the second can't be *. If I got that right

@Portur thanks for logging the issue and the detailed investigation that you took on. I'm going to do my best to take a look at the issue properly in the next few days.

@DamonOehlman, did you find time to have a second look at this? 😄

[DamonOehlman]

@AnandChowdhary @Portur to be honest, I got completely distracted by other things (as you can probably tell). I've added myself a calendar note to take a look at this tonight.

Hey folks - apologies again for the delay. I investigated the above (and added a couple of additional tests to cover the * case). I think what you are experiencing comes down to a couple of things:

1. I never bumped and published a version after merging Properly support wildcard when not in a section of its own #11 which makes the "naked wildcard" (*) behave as it should. So tests against [email protected] would fail in that case, which is what you are seeing above.

2. The use case that you described where there is a comma separated list of patterns, e.g. domainMatch( '*, localhost ', 'localhost' ) is not something that is supported by wildcard and thus it will always return false. So yes you are right the format the wildcard expects arguments is:

wildcard(matchPattern, test)

Where test can either be a string, or an array of strings that will be filtered. As an aside, I think adding the support for checking on an array was a mistake and something I should have built differently.

---

Anyway, I have bumped the version of wildcard to 2.0.0 as technically the way the * is interpreted now vs before is definitely a breaking change and deserves a major upgrade. If you feel like taking it for a spin to see if it behaves how you think it should then please do and let me know.

This is great, thank you!
