|
|
|
+//
|
|
|
+// 1. Get the minimatch set
|
|
|
+// 2. For each pattern in the set, PROCESS(pattern, false)
|
|
|
+// 3. Store matches per-set, then uniq them
|
|
|
+//
|
|
|
+// PROCESS(pattern, inGlobStar)
|
|
|
+// Get the first [n] items from pattern that are all strings
|
|
|
+// Join these together. This is PREFIX.
|
|
|
+// If there is no more remaining, then stat(PREFIX) and
|
|
|
+// add to matches if it succeeds. END.
|
|
|
+//
|
|
|
+// If inGlobStar and PREFIX is symlink and points to dir
|
|
|
+// set ENTRIES = []
|
|
|
+// else readdir(PREFIX) as ENTRIES
|
|
|
+// If fail, END
|
|
|
+//
|
|
|
+// with ENTRIES
|
|
|
+// If pattern[n] is GLOBSTAR
|
|
|
+// // handle the case where the globstar match is empty
|
|
|
+// // by pruning it out, and testing the resulting pattern
|
|
|
+// PROCESS(pattern[0..n] + pattern[n+1 .. $], false)
|
|
|
+// // handle other cases.
|
|
|
+// for ENTRY in ENTRIES (not dotfiles)
|
|
|
+// // attach globstar + tail onto the entry
|
|
|
+// // Mark that this entry is a globstar match
|
|
|
+// PROCESS(pattern[0..n] + ENTRY + pattern[n .. $], true)

+// else // not globstar

+// Test ENTRY against pattern[n]
