Alexander Neumann 9630398e3b ls: Rework and simplify logic ... This commit introduces two functions: withinDir() and approachingMatchingTree() Both bind the list of directories with a closure, so we don't need to iterate over the list in the function passed to Walk(). This reduces the indentation level and since we can just use return, we don't need the breaks any more. The case that len(dirs) == 0 can also be handled by the functions with a return, which saves another indentation level. The main function body of the function passed to Walk() was reduced to three cases: * Within one of the dirs: Print the node, and if recursive operation is requested, directly return, so the walker continues recursive traversal * Approaching one of the dirs: don't print anything, but continue recursive traversal. * Nothing of the two: abort walking this branch of the tree.		2018-08-12 23:13:34 +02:00
