Hi igoryonya,

i would refer to the documentation. PLS

there is no mentioning of renaming/refactoring.

The Perl Language Server implements a subset of the Language Server Protocol for the Perl language. Features currently implemented are:

• Go to definition (for packages, subroutines, and variables)
• Listing all symbols in a document
• Hovering to show documentation
• Signature help (showing parameters for a function as you type)
• Formatting
• Range Formatting
• Auto-completion
• Syntax checking
• Linting (using perlcritic)
• Sorting imports

Perl::LanguageServer also does not mention support of this feature.

you could look at Damian Conway's vim setup.
