| // Approach:
 | |
| //
 | |
| // 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
 | |
| //     for ENTRY in ENTRIES (not dotfiles, unless pattern[n] is dot)
 | |
| //       Test ENTRY against pattern[n]
 | |
| //       If fails, continue
 | |
| //       If passes, PROCESS(pattern[0..n] + item + pattern[n+1 .. $])
 | |
| //
 | |
| // Caveat:
 | |
| //   Cache all stats and readdirs results to minimize syscall.  Since all
 | |
| //   we ever care about is existence and directory-ness, we can just keep
 | |
| //   `true` for files, and [children,...] for directories, or `false` for
 | |
| //   things that don't exist.
