Tern
Tern est un analyseur de code indépendant de l'éditeur et un moteur d'analyse statique pour JavaScript. Il fonctionne comme un serveur de langage qui fournit une intelligence sémantique en analysant le code source en arbres de syntaxe abstraits pour déduire les types et résoudre les symboles sans nécessiter d'annotations de type manuelles.
Le moteur se distingue par l'utilisation de définitions de type basées sur JSON, qui lui permettent de décrire les signatures de bibliothèques et les dépendances externes sans avoir besoin du code source original. Il dispose également d'un système de plugins qui permet l'extension des fonctionnalités du serveur pour prendre en charge des loaders ou frameworks personnalisés.
Le projet couvre de larges domaines de capacités incluant la navigation dans le code, le refactoring et l'autocomplétion dans l'éditeur. Il fournit des services tels que la localisation des définitions de symboles, la recherche de références de code et l'offre d'indices et de complétions d'arguments de fonction basés sur les types d'expression déduits.
Features
- Language Intelligence Services - Provides deep semantic analysis of JavaScript code to enable advanced navigation and understanding in editors.
- JSON Library Type Definitions - Utilizes JSON-based type definitions to describe library signatures and external dependencies without needing original source code.
- Semantic Code Analyzers - Performs semantic analysis to resolve symbols and find definitions and references within JavaScript code.
- Code Completion - Recommends variables and keywords at the cursor based on inferred types and documentation metadata.
- Editor Code Navigation - Provides essential capabilities for jumping to definitions, finding references, and renaming symbols across files.
- JavaScript Language Servers - Implements a backend language server that provides completion, symbol resolution, and refactoring for JavaScript.
- Language Server Implementations - Functions as an editor-independent analysis engine providing language intelligence services via a common interface.
- Custom Type Definitions - Uses JSON-based signatures to describe external library types when the original source code is unavailable.
- JavaScript Static Analysis - Analyzes JavaScript source code without execution to infer variable types and ensure project consistency.
- JavaScript Static Analyzers - Functions as a static analysis engine that parses JavaScript into abstract syntax trees to provide semantic intelligence.
- Static Type Inference - Determines data types by analyzing variable and property contexts without requiring manual type annotations.
- Symbol Definition Resolution - Locates the original declaration of a variable, function, or class by analyzing semantic information.
- Static Source Code Type Inference - Implements a core engine that infers JavaScript types by analyzing the abstract syntax tree of source code.
- Symbol Resolution - Provides a mechanism to map identifiers to their original declarations by analyzing semantic and type information.
- Expression Type Resolution - Determines the expected data types of expressions during the static analysis phase.
- Code Autocomplete Engines - Provides context-aware code completions for symbols and properties as the user types.
- Code Refactoring Tools - Provides capabilities to rename symbols and restructure code while maintaining logical consistency.
- Code Reference Locators - Implements the ability to search the syntax tree and locate every occurrence of a specific variable or property.
- External Dependency Resolvers - Locates and prepares external code dependencies using standard resolution strategies.
- JavaScript Symbol Resolvers - Provides the capability to locate variable definitions and find all references to specific symbols across a project.
- Type Determination - Retrieves the resulting data type of specific code expressions without executing the code.
- Expression Type Inspectors - Inspects and reports the static type of specific code expressions to assist with debugging.
- Function Argument Hints - Displays expected parameter types and descriptions when a function is invoked to ensure correct usage.
- Module Path Resolution - Implements rules for locating external code dependencies using industry-standard path and naming patterns.
- Parameter Usage Hints - Displays expected arguments for functions to help users call them with the correct parameters.
- User-Defined Types - Allows specifying function signatures and types via a structured format to describe external libraries.
- Automatic Variable Type Inference - Identifies the inferred type of specific expressions to ensure data consistency and correctness.
- Sponsored Projects - Funded through a community-driven crowdfunding campaign.
- Sustainable Project Examples - Releases language expansion packs via crowdfunded campaigns.
