Modules for building friendly CLI scripts?

jimpudar has asked for the wisdom of the Perl Monks concerning the following question:

Hello esteemed monks,

I came across this article on auto-completion in Bash scripts, and heard about Click for Python.

I build command line applications a lot in Perl, and I'm wondering if there is anything similar.

Today, my weapons of choice are Getopt::Long and Pod::Usage, but I don't get any of the magic auto-completion you would get with Click.

Any suggestions would be most appreciated!

Best,

Jim

Hello jimpudar, Tab completion is provided by the core module Term::ReadLine and you can manipulate the completion with some effort. See Re^3: about Term::ReadLine and it's imported function The Solution for a working example. You can also be interested into tinita's API-CLI and maybe in the presentation she made some years ago: Writing command line tools made easy‎ - YAPC::Europe 2016 L* PS see also Term::UI Term::Menus Term::ShellUI and Term::CLI and also an interesting list at Task::Kensho::CLI:-Useful-Command-line-Tools There are no rules, there are no thumbs..

I recently played around with IO::Prompter and thought it was pretty nice. It features input autocompletion as well.	[reply]
