Print your target is a Visual Studio Code extension for quickly adding and removing log statements in JavaScript, TypeScript, and Go files. Now powered by AST analysis for intelligent and precise code insertion.

✨ New in v0.1.1 - Performance Optimizations

🚀 Major Improvements

  • AST-Based Analysis: Uses TypeScript compiler API for accurate code understanding
  • Smart Expression Detection: Intelligently identifies variables, functions, objects, and complex expressions
  • Context-Aware Insertion: Finds optimal insertion points based on code structure
  • Robust Log Removal: Precisely locates and removes log statements without false positives

功能 Features

添加日志语句 Add Log Statements

  • 智能分析: AST-powered analysis understands your code context
  • 自适应日志类型: Automatically selects appropriate console methods:
    • console.error() for error-related variables
    • console.info() for async operations
    • console.debug() for function calls
    • console.warn() for conditional expressions
    • console.log() for general variables
  • 精确插入: Inserts at syntactically correct locations
  • 复杂表达式支持: Handles complex expressions with object destructuring format

删除日志语句 Remove Log Statements

  • AST精确匹配: Uses AST analysis to find exact log statements
  • 批量删除: Removes multiple log statements efficiently
  • 无误删: Avoids removing non-log code that might match patterns

快捷键

  • 添加日志语句:
    • Windows/Linux: Ctrl+Shift+L
    • macOS: Cmd+Shift+L
  • 删除日志语句:
    • Windows/Linux: Ctrl+Shift+D
    • macOS: Cmd+Shift+D

配置项

错误关键字

  • printYourTarget.errorKeywords.javascript: 定义 JavaScript/TypeScript 中的错误关键字，默认值为 ["error", "err", "e"]。
  • printYourTarget.errorKeywords.go: 定义 Go 中的错误关键字，默认值为 ["err", "error"]。

日志类型

  • printYourTarget.deleteLogType.javascript: 定义 JavaScript/TypeScript 中需要删除的日志类型，默认值为 ["log"]。
  • printYourTarget.deleteLogType.go: 定义 Go 中需要删除的日志类型，默认值为 ["Printf"]。

安装

  1. 从 Print your target - Visual Studio Marketplace 安装扩展。
  2. 或者下载 .vsix 文件并通过 VS Code 的扩展管理器手动安装。

使用方法 Usage

Basic Usage

  1. 打开一个 JavaScript、TypeScript 或 Go 文件
  2. 选中需要打印的变量或表达式 (或将光标放在变量上)
  3. 使用快捷键或命令面板运行命令

Smart Examples

// Select 'user.name' -> Generates:
console.log('user.name value:', user.name);

// Select 'calculateScore(data)' -> Generates:  
console.debug('calculateScore() result:', calculateScore(data));

// Select 'await response.json()' -> Generates:
console.info('response.json() result:', await response.json());

// Select 'error' (error keyword) -> Generates:
console.error('error:', error);

// Complex expression -> Generates:
console.log('users.filter() result:', { users: users.filter(u => u.isActive) });
