Given a path string, return a generator that walks up the path, emitting each dirname.
So, to get a platform-portable walk up, instead of doing something like this:
for (let p = dirname(path); p;) {
// ... do stuff ...
const pp = dirname(p)
if (p === pp)
p = null
else
p = pp
}Or this:
for (let p = dirname(path); !isRoot(p); p = dirname(p)) {
// ... do stuff ...
}You can do this:
const { walkUpPath } = require('walk-up-path')
for (const p of walkUpPath(path)) {
// ... do stuff ..
}const { walkUpPath } = require('walk-up-path')Give the fn a string, it'll yield all the directories walking up to the root.
