;;; test-dirvish-config-dired-line-directory.el --- Tests for the directory-line predicate -*- lexical-binding: t; -*-

;;; Commentary:
;; `cj/--dired-line-is-directory-p' is the testable predicate behind
;; `cj/dired-mark-all-visible-files'.  Dired buffers prefix each file
;; line with a one-char mark column followed by the `ls -l' output, so
;; column 2 is the file-type letter (`d' for directory, `-' for regular
;; file).  The wrapper iterates the buffer and skips lines this
;; predicate returns t for; the iteration stays dired-coupled and
;; untested, but the line-classification logic is now isolated.
