=={{header|Perl 6}}==

Perl 6 has a built in REPL that can be initiated by running the perl6 executable without any parameters. It is fairly basic on its own but here are bindings available in the Perl 6 ecosystem for [https://tiswww.case.edu/php/chet/readline/rltop.html GNU Readline] and/or [https://github.com/antirez/linenoise Linenoise] either of which will automatically provide command history, tab completion and more advance command line editing capability if installed. They are not included in the Perl 6 distribution directly. There are incompatible licensing requirements and providing hooks for third party tools allows for more customization options.

Linenoise is generally the preferred option unless you really want the emacs compatible command line editing key bindings. Readline is arguably more powerful but is somewhat fiddly to set up.

If you are not inclined to install Readline ''or'' Linenoise, the REPL also works fairly well with 3rd party tools like rlwrap.
