perl-semantic-analyzer

Semantic analysis for Perl source.

Use this crate when you already have an AST and need symbols, scopes, types, declaration lookup, or dead-code signals before you get to editor features.

Where it fits

perl-semantic-analyzer sits above perl-parser-core and next to perl-workspace-index. It turns parsed trees into analysis artifacts that the workspace, refactoring, and LSP layers can consume.

Key entry points

• analysis::symbol::SymbolExtractor
• analysis::scope_analyzer::ScopeAnalyzer
• analysis::type_inference::TypeInferenceEngine
• analysis::semantic::SemanticAnalyzer
• analysis::declaration::DeclarationProvider
• analysis::index::WorkspaceIndex

Example

use perl_parser_core::Parser;
use perl_semantic_analyzer::analysis::symbol::SymbolExtractor;

let mut parser = Parser::new("sub hello { my $x = 1; }");
let ast = parser.parse()?;
let _symbols = SymbolExtractor::new().extract(&ast);

Typical use

Use perl-semantic-analyzer when you are building hover, declaration, type, or diagnostics features from parsed Perl source. If you need cross-file lookup or document caching, pair it with perl-workspace-index.
