perl-lsp-diagnostics

Perl diagnostics engine for editor-facing parse errors, lint checks, semantic warnings, and dead-code reporting. This crate turns parser and analysis results into publishDiagnostics-style output.

Use this crate when

Use perl-lsp-diagnostics if you need the diagnostic logic itself. If you only need the shared diagnostic types, depend on the re-exported types rather than rebuilding the provider stack. If you want the umbrella API, use perl-lsp-providers.

Key exports

• DiagnosticsProvider - assembles diagnostics from AST, source, and optional workspace context
• Diagnostic, DiagnosticSeverity, DiagnosticTag, RelatedInformation - shared diagnostic types
• common_mistakes, deprecated, missing_module, package_subroutine, security, strict_warnings, unused_imports, version_compat - lint families re-exported for targeted checks
• detect_dead_code - workspace-wide dead-code detection outside WASM builds

Example

use perl_lsp_diagnostics::DiagnosticsProvider;

let provider = DiagnosticsProvider::new();
let diagnostics = provider.generate_diagnostics(&ast, source, Some(&workspace_index))?;

Stack role

This crate sits between parsing and the editor runtime. It consumes ASTs, scope analysis, and workspace data, then emits the diagnostics that perl-lsp publishes to clients.
