Calls the block with each entry name in the directory at dirpath; sets the given encoding onto each passed entry_name:
Example
Dir.foreach('/example') {|entry_name| p entry_name }
Output:
Example
"config.h" "lib" "main.rb" ".." "."
Encoding:
Example
Dir.foreach('/example') {|entry_name| p entry_name.encoding; break } Dir.foreach('/example', encoding: 'US-ASCII') {|entry_name| p entry_name.encoding; break }
Output:
Example
#<Encoding:UTF-8> #<Encoding:US-ASCII>
See String Encoding.
Returns an enumerator if no block is given.
