Yet Another Shell

Fork

Yet another shell, version 2.47.

This version introduces the "err-return" option and fixes some bugs.

Yash 2.47

• Added: '--errreturn' option.
• Changed: Expansion results printed by the -x option is now quoted to disambiguate presence of special characters.
• Changed: When the shell prints aliases, variables, key bindings, etc. they are now printed with less quotes.
• Fixed: The "set" built-in without any argument now prints not only local variables but also global.
• Fixed: The "." built-in no longer leaves temporary positional parameters after a file-not-found error.
• Fixed: The ">" redirection with the noclobber option is now more reliable than before. Previously, there was little possibility of overwriting an existing regular file in case another process simultaneously replaces the file.
• Updated the sample initialization script (yashrc):
  • Added: Example code for enabling "direnv".
