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

Hi

I'm a bit puzzled, I installed reply via ActiveState ppm (5.24) on Win10 and the inline editing supports the usual GNU/Emacs commands like CTRL-a -e -k -y and so on

But the standard perldebugger doesn't.

Both use Term::ReadLine and the environment var PERL_RL isn't set to another backend.

Does anyone have insight how reply is achieving this and if and how I can activate this inside the debugger too?

(NB: The Term::ReadLine::Gnu backend is not available for ActiveState/Win )

I already browsed thru reply's repository but couldn't find a hint...

PS: Reply is actually a pretty cool tool, but might need a better tutorial to show it's features.

    idk if this would be helpful, but readline is what gives you line navigation in a shell, right? You said like in emacs, but I think most would know it for using to jump to the start (CTRL-a) and end (CTRL-e) of lines in the shell as you're typing; I know mysql cli client supports it, *nix shells, etc.

    It is a library that must be available, so if it's not available the Perl interfaces are probably going to not function (but also not break):

    On windows, the readline library page says, "If you are running Windows, I recommend that you use Cygwin, who currently ship readline-7.0 for x86 and readline-7.0 for x86_64, or MinGW, which currently has packages for readline-5.2.". My first thought was to suggest installing the library via cygwin, and this is pretty much what they suggest also.

    So checkout https://tiswww.case.edu/php/chet/readline/rltop.html and maybe adding it via Cygwin will help - not sure how to link up the RL modules or how setting PERL_RL may be involved, but hopefully this gives you some new ideas.

      Thanks, but I need to use the debugger interactively in the same environment like my client, and that's unfortunately active state for 5.24.

      My guess so far - we had similar discussions before - was that AS messed it up.

      That's why I asked how Reply - great tool BTW - solved it.

      Apart from this I'm very interested to have an out of the box REPL in CORE. I think that's crucial for Perl. :)
