Module: SimpleCov::CLI::JDKRealPath

Extended by:
JDKRealPath
Included in:
JDKRealPath
Defined in:
lib/simplecov/cli/real_path.rb

Overview

The JDK's answer to File.realpath and File.realdirpath, for JRuby. On Windows JRuby's own versions follow no symlinks, and realdirpath accepts a directory that does not exist, so the CLI's containment and identity checks would compare paths that were never resolved. Path#toRealPath has neither problem on any OS. The path is expanded first because the JDK resolves a relative path against the JVM's working directory, which Dir.chdir does not move.
