Issue #15244 has been updated by nobu (Nobuyoshi Nakada). If `File.extname("..jpg")` returns `".jpg"`, `File.basename("..jpg", ".*")` should return `"."` without that part, to restore the original name from from these results. It is different from basename(1). ``` $ basename ..jpg '.*' ..jpg ``` ---------------------------------------- Bug #15244: Method #extname return empty string if filename is dot ('.') https://bugs.ruby-lang.org/issues/15244#change-74652 * Author: TiSer (Sergey TiSer) * Status: Open * Priority: Normal * Assignee: * Target version: * ruby -v: 2.5.0p0 * Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN ---------------------------------------- ### Example 1: Current behaviour: ``` File.extname('..jpg') => "" ``` Expected behaviour: ``` File.extname('..jpg') => ".jpg" ``` ### Example 2: Current behaviour: ``` File.extname('....jpg') => "" ``` Expected behaviour: ``` => ".jpg" ``` -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request / ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
