Debugging: F5 runs the Debug Perl launch entry. It finds the first perl or prove command in main.sh, or in a script main.sh runs, and debugs that file in that working directory with its arguments and the environment variables main.sh exports or sets on that command. It also puts its -I directories, prove -l and PERL5LIB directories on PERL5LIB. For prove it debugs the first test file only. Input redirection is not applied, and the program reads end of file from standard input. Without such a command it debugs the open .pl file, or main.pl or solution.pl. A breakpoint in a file loaded with do applies only once the file has loaded.

The setup script patches Perl::LanguageServer 2.6.2 so that the program's standard input is closed, files loaded by a relative path (require './solution.pl') get breakpoints and absolute paths in the call stack, and Run Without Debugging doesn't stop at breakpoints.
