|
|
// Approach:
|
|
|
|
//
|
|
|
|
// 1. Get the minimatch set
|
|
|
|
// 2. For each pattern in the set, PROCESS(pattern)
|
|
|
|
// 3. Store matches per-set, then uniq them
|
|
|
|
//
|
|
|
|
// PROCESS(pattern)
|
|
|
|
// 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.
|
|
|
|
// readdir(PREFIX) as ENTRIES
|
|
|
|
// If fails, END
|
|
|
|
// 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 .. $])
|
|
|
|
// // handle other cases.
|
|
|
|
// for ENTRY in ENTRIES (not dotfiles)
|
|
|
|
// // attach globstar + tail onto the entry
|
|
|
|
// PROCESS(pattern[0..n] + ENTRY + pattern[n .. $])
|
|
|
|
//
|
|
|
|
// 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.
