Class Method Details

.each_env_path(command, env_path_var: ENV.fetch("PATH", nil)) {|path| ... } ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Loop through each path in global PATH environment variable to perform an operation in each path, for example to resolve absolute path to a command.

NOTE: This has nothing to do with Config#env_paths, as the env paths looped are what the system has defined, in ENV.

Should be cross-platform.

Yields:

  • Command appended to each path in PATH environment variable

Yield Parameters:

  • path (String) —

    Full path to executable
