It would be nice to have the syntax highlight working in Markdown files (fenced code blocs with raku code) (for the vscode extension).

I believe this has something to with Embedded languages

According to the raku docs, this code should work

my ($first, $second) = qq:to/END1/, qq:to/END2/; 
  FIRST
  MULTILINE
  STRING
  END1
   SECOND
   MULTILINE
   STRING
   END2 
say $first;  # OUTPUT: «FIRST␤MULTILINE␤STRING␤»
say $second; # OUTPUT: «SECOND␤MULTILINE␤STRING␤»

while the syntax could only recognize (which could not compile)

my ($first, $second) = qq:to/END1/, qq:to/END2/; 
   SECOND
   MULTILINE
   STRING
   END2 
  FIRST
  MULTILINE
  STRING
  END1
say $first;  # OUTPUT: «FIRST␤MULTILINE␤STRING␤»
say $second; # OUTPUT: «SECOND␤MULTILINE␤STRING␤»

It would be nice to have the a raku script that outputs the list of installed and available raku modules. This could be used in autocomplete following a "use" statement. The Perl Navigator already has a script that generates this for Perl ( https://github.com/bscan/PerlNavigator/blob/main/server/src/perl/lib_bs22/ModHunter.pl ). Note that this should include local available modules from the workspace, and not simply be a list of installed modules from zef.

To syntax check a file, navigator.raku parses the code with nqp and also compiles it. I need the parsed output because of the is helpful for identifying the end of subs and class declaration. However, compilation is also important because of additional checks that happen in the optimize phase (e.g. subroutine signature mismatches). Currently, I am parsing the code twice which is slow and results in use statements being evaluated twice. I would like to update this code to compile only once, while still returning the $parsed code. https://github.com/bscan/RakuNavigator/blob/master/server/src/raku/navigator.raku

In the following (pointless) code:

unit sub MAIN;

The unit keyword is not highlighted:

Currently, there is no information on separating the language server from the VSCode extension. For users of other editors, it might be good to provide instructions for installing the server outside of VSCode to be used in something like Neovim.

First -- thank you for working on this project!

After installing the extension I cannot run Raku scripts with it.

I made a few changes in the corresponding "settings.json" as suggested in the README. I still cannot run scripts.

I assume I am configuring the paths in the wrong way.

From README is not clear (exactly) where and how to place these configurations:

raku.rakuPath specifies the location of your raku install. Defaults to "raku"
raku.includePaths adds locations to the path via a -I command line switch

Currently if someone uses the vscode.dev version (or github version by pressing "." in a github repo), Raku code does not render well. The Navigator could be upgraded to a web extension which would provide syntax highlighting and snippets in the browser. The language server would not work due to the lack of Raku backend.

I've gotten errors to appear but I can't get syntax highlighting to work in Helix. Is there something I'm missing in my languages.toml?

[language-server.rakunavigator]
command = "node"
args = ["/home/dan/Programs/RakuNavigator/server/out/server.js", "--stdio"]

[[language]]
name = "raku"
scope = "source.raku"
file-types = ["raku", "rakudoc"]
comment-tokens = "#"
language-servers = ["rakunavigator"]

Currently, the raku source is compiled using nqp::getcomp. This could run BEGIN and CHECK blocks, but a regex strips these phasers out. This should ideally be controlled by a setting. Some people may want to run these blocks (e.g. BEGIN block being required to set a path). This would also be the first of multiple compilation "modes" if we identify other methods of parsing.

Hi can you push your extension to https://open-vsx.org/ in addition to VSCode Market Place so people using the FLOSS version could install it too?

I wrote an article on the subject.

Example of Github Action: https://github.com/HaaLeo/publish-vscode-extension

I'm getting an error that the editor cannot find the lib when in the test file, but prove6 runs correctly.

Here is the folder structure:

├── HELP.md
├── README.md
├── lib
│   └── Pangram.rakumod
└── t
    └── pangram.rakutest

And here's the top of the test file:

use Test;
use lib $?FILE.IO.parent(2).add('lib');
use Pangram;

This is the full error:

I'm running the Raku VS Code extension v0.3.2, Rakudo v2024.02 on macOS 14.2.1 (M1 Pro).

The Perl Navigator parses the symbol table to find imported functions, and then gets the file and line number from them. I would like to do something similar for Raku, but parsing the symbol table is not finding the results I need. I use nqp to parse and compile code in https://github.com/bscan/RakuNavigator/blob/master/server/src/raku/navigator.raku and then I would like to dump the symbol table. The following snippet works from within a script, but I would like to parse the symbol table from the $compiled code instead. Pull requests are more than welcome.

for ::.kv -> $k, $v {
    if ($k.starts-with('&')) {
         print $k, $v.signature.gist(), $v.file, $v.line;
    }
}

I have a raku module installed:

zef list --installed | grep ^BDD                                                                                                                                                       ─╯
===> Found via /Users/gd/rakudo/share/perl6/site
===> Found via /Users/gd/rakudo/share/perl6/core
BDD::Behave:ver<0.0.4>:auth<github:gdonald>

And I'm getting this error:

My code works, but vscode thinks it's broken.

Further down when I use the module like this:

It gives me this weird error I do not get when I run my code. This code is supported by a Raku Grammer, so that may be related:

Again, works fine when I run it, just that vscode thinks it's broken and underlines it with red.

The Raku syntax highlighting is currently taken from the Atom extension here: https://github.com/Raku/atom-language-perl6/. This is also the syntax that powers Github, so is an important repo. Currently, I've only ported the core syntax and not the regex syntax or quoting files. For example, see the following highlighting in github. Vscode does not highlight \d. I assume this would be straightforward to incorporate.

$foo ~~ /Foo\d+bar/;

This doesn't necessarily mean a formal automated test suite (although that would be great too). Primarily we need a few Raku files to exercise the full set of features, especially around the different types of errors and warnings that the Raku compiler can generate, and the types of constructs that the Raku tagger is looking for.

I get these messages from the syntax check while there is no duplication of the particular symbol. In this case, it trips over the line

unit class QA::Gui::InputWidget:auth<github:MARTIMM>;

It has the same problems with other modules in the same project when using unit. I've tried to rephrase this declaration

class QA::Gui::InputWidget:auth<github:MARTIMM> does QA::Gui::Frame {

having a different error

Syntax: QA::Gui::Frame is not composable, so QA::Gui::InputWidget cannot compose it

This class was declared like a class instead of a role. However, the error was still there after the change.

Note also that raku didn't have any trouble compiling the code.

Thanks for building this!

The following code:

say "\c[CHECK MARK]";

results in an error:

Syntax: Unrecognized character name [ENTER MARK]
raku navigator

CHECK and ENTER are both phasers, so maybe that's where it gets confused?

Currently many of the regexes in https://github.com/bscan/RakuNavigator/blob/master/server/src/raku/navigator.raku are perl5 compatibility mode regexes. For a variety of reasons, they should probably updated to native Raku.

In my settings.json I have added the full path to my lib directory in my Raku module:

"raku.includePaths": [
    "/Users/gd/workspace/raku/Console-Blackjack/lib"
]

But my code does not then find anything in my lib directory:

The path I defined in settings.json doesn't appear in the list of paths it's searching. Any idea? Thanks.
