| // 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. | |
