Language Server and Debug Protocol Adapter for Perl
You need to install the perl module Perl::LanguageServer to make this extension work,
Please make sure to always run the newest version of Perl::LanguageServer as well.
NOTE: Perl::LanguageServer depend on AnyEvent::AIO and Coro. There is a warning that this might not work with newer Perls. It works fine for Perl::LanguageServer. So just confirm the warning and install it.
Perl::LanguageServer depends on other Perl modules. It is a good idea to install most of then with your linux package manager.
e.g. on Debian/Ubuntu run:
In case any of the above packages are not available for your os version, just
leave then out. The cpan command will install missing dependencies. In case
the test fails, when running cpan
This extension contributes the following settings:
Debugger Settings for launch.json
Remote syntax check & debugging
If you developing on a remote machine, you can instruct the Perl::LanguageServer to run on that remote machine, so the correct modules etc. are available for syntax check and debugger is started on the remote machine. To do so set sshAddr and sshUser, preferably in your workspace configuration.
Also set sshWorkspaceRoot, so the local workspace path can be mapped to the remote one.
Example: if your local path is \10.11.12.13\share\path\to\ws and on the remote machine you have /path/to/ws
The other possibility is to provide a pathMap. This allows to have multiple mappings.
Syntax check & debugging inside a container
You can run the LanguageServer and/or debugger inside
a container by setting
Working directory is not defined
It is not defined what the current working directory is at the start of a perl program. So Perl::LanguageServer makes no assumtion about it. To solve the problem you can set the directory via cwd configurationm parameter in launch.json for debugging.
Module not found when debugging or during syntax check
If you reference a module with a relative path or if you assume that the current working directory is part of the Perl search path, it will not work. Instead set the perl include path to a fixed absolue path. In your settings.json do something like:
Include path works for syntax check and inside of debugger.
AnyEvent, Coro Warning during install
You need to install the AnyEvent::IO and Coro. Just ignore the warning that it might not work. For Perl::LanguageServer it works fine.
'richterger.perl' failed: options.port should be >= 0 and < 65536
Change port setting from string to integer
Error "Can't locate MODULE_NAME"
Please make sure the path to the module is in
ERROR: Unknow perlmethod _rpcnot_setTraceNotification
This is not an issue, that just means that not all features of the debugging protocol are implemented. Also it says ERROR, it's just a warning and you can safely ignore it.
The debugger sometime stop a random places
Upgrade to Version 2.4.0
Message about Perl::LanguageServer has crashed 5 times
This is an problem when more then one instance of Perl::LanguageServer is running. Upgrade to Version 2.4.0 solve this problem.
If you are using Carton to manage dependencies, add the full path to the Carton
Does not yet work on windows, due to issues with reading from stdin. I wasn't able to find a reliable way to do a non blocking read from stdin on windows. I would be happy, if anyone knows how to do this in Perl.
Anyway Perl::LanguageServer runs without problems inside of Windows Subsystem for Linux (WSL).

This is a Language Server and Debug Protocol Adapter for Perl
It implements the Language Server Protocol which provides syntax-checking, symbol search, etc. Perl to various editors, for example Visual Studio Code or Atom.
It also implements the Debug Adapter Protocol, which allow debugging with various editors/includes
To use both with Visual Studio Code, install the extension "perl"
Any comments and patches are welcome.
