Base class package "Class::Accessor" is empty.
    (Perhaps you need to 'use' the module which defines that package first,
    or make that module available in @INC (@INC contains: /Users/dcavanagh1/perl5/lib/perl5/darwin-thread-multi-2level /Users/dcavanagh1/perl5/lib/perl5 /usr/local/Cellar/perl/5.34.0/lib/perl5/site_perl/5.34.0/darwin-thread-multi-2level /usr/local/Cellar/perl/5.34.0/lib/perl5/site_perl/5.34.0 /usr/local/Cellar/perl/5.34.0/lib/perl5/5.34.0/darwin-thread-multi-2level /usr/local/Cellar/perl/5.34.0/lib/perl5/5.34.0 /usr/local/lib/perl5/site_perl/5.34.0).

Class::Accessor is up to date. (0.51)

any ideas?

I don't see $NVIM_LISTEN_ADDRESS being used in this repo but just a heads up.

neovim/neovim#11009 (Nvim 0.8+) will change Nvim so that $NVIM_LISTEN_ADDRESS is not passed to child processes. After that, the correct way to detect a "host" or "parent" Nvim is to check for $NVIM env var: this means the current process is a child of Nvim.

The old $NVIM_LISTEN_ADDRESS env var had conflicting purposes as both a parameter ("the current process should listen on this address") and a descriptor ("the current process is a child of this address").

I tested with a 1 line buffer with these 3 characters only:

a漢a

$curwin->Cursor yields
(1,0) (1,1) and wrongly (1,4) instead of (1,2)

:checkhealth in Neovim 0.5.0 shows me that everything is fine with Perl integration:

## Perl provider (optional)
  - INFO: perl executable: /nix/store/xwqsqp6clmd6z9l91ajqzd57qqlkp2gl-perl-for-neovim/bin/perl
  - OK: Latest "Neovim::Ext" cpan module is installed: 0.05

But when I type :perl whatever or :perldo whatever or :perlfile whatever nothing happens, no errors reported. Any thoughts why? It doesn’t matter what the arguments are. I could type something correct like :perl print "hi" or :perl VIM::Msg("hi"), no effect. 🤷

I test the function of this provider by running nvim --clean, then run :perl print "Hi", and I get the following error:

I already set the environment variable, but does not come the log file.

How can I fix this?

neovim/neovim#11703 allows Neovim to run perl plugins via this perl module but this module is missing the RPC methods required for if_perl interface. neovim has all the pieces required to run :perl on its end so I need only the RPC methods (ie. perl_execute) from this module on a session (perl-client), a host (perl-rplugin-host), or a "backend" plugin for some host like the ruby provider. I can handle the rest.

Examples from other providers:

• python: https://github.com/neovim/pynvim/blob/master/pynvim/plugin/script_host.py
• ruby: https://github.com/neovim/neovim-ruby/blob/master/lib/neovim/ruby_provider.rb
