javascript - Node-Minimatch/Regex: Match subdirectories within a specified subdirectory -

i match subfolders within given subfolder.

let's have following directories:

test/rock/martin test/rock/steven test/rock/steven/coolmusik test/rock/steven/coolmusik/newmusic  test/pop/martin test/pop/steven test/pop/steven/mysubdir test/pop/steven/anothersubdir 

---

now i'd match in 'rock' , 'pop', restriction of given name. in case it's 'steven'.

the following minimatch glob-rule works fine far:

minimatch('./test', ['!*(rock|pop|steven)'], {matchbase: true})) 

translation of rule above:

hide not in rock , pop , steven.

---

but here's problem: 1 can imagine minimatch doesn't include subdirectories in particular case.

i want like...

minimatch('./test', ['!*(rock|pop|steven|plus_subdirs_of_steven)'], {matchbase: true})) 

...but sadly didn't work rule:

minimatch('./test', ['!*(rock|pop|steven/**)'], {matchbase: true})) 

my question is: how can hide things except rock+pop+steven+steven's subdirectories ?

---

a better overview of directory-structure:

test |-rock |--martin |--steven |---coolmusik |----newmusic |-pop |--martin |--steven |---mysubdir |---anothersubdir 

---

also: if there's no way minimatch can handle this, how regular regex rules above like?

you cannot .gitignore-style behavior making list of every file , glob-matching each one. starters, that's ludicrously expensive (you may have .gitignore'd folder 100000 files in or something), , also, have keep track of whether parent ignored. however, gets more complicated, because rule might cause have specific items, if they're un-ignored negated rule.

the owner of 'minimatch' wrote module called fstream-ignore solves problem. however. definately out of scope , not related question. end regular javascript regex, mentioned in original post.

regex:

new regexp(^test\/(rock|pop)(?:\/|$)(?:steven|$)(?:\/.*|$)$); 

---

example:

var re = /^test\/(rock|pop)(?:\/|$)(?:steven|$)(?:\/.*|$)/mg;  var paths = 'test/rock/martin\ntest/rock/steven\ntest/rock/steven/coolmusik\ntest/rock/steven/coolmusik/newmusic\ntest/pop/martin\ntest/pop/steven\ntest/pop/steven/mysubdir\ntest/pop/steven/anothersubdir';    var match;    while ((match = re.exec(paths)) !== null) {    if (match.index === re.lastindex) {      re.lastindex++;    }    var old_content = document.getelementbyid('results').innerhtml;    document.getelementbyid('results').innerhtml = old_content + '<br>' + match[0];  }
