godot-verify

Validate Godot GDScript files using gdlint, gdformat, gdradon, and LSP diagnostics. Use when users want to: (1) Check code quality after making changes, (2) Validate before committing, (3) Run code metrics analysis, (4) Run export validation, (5) Get real-time LSP diagnostics. Uses command-line tools directly and MCP tools for LSP integration.

Godot Verification Skill

Validate Godot project changes using gdlint, gdformat, gdradon, godot export commands, and LSP diagnostics.

排除规则

不要检查和处理 addons 目录下的任何文件。

addons 目录通常包含第三方插件或外部资源,这些代码不由项目维护,不应纳入项目代码质量检查范围。

检查项

| 检查 | 命令/工具 | 说明 | |------|----------|------| | Lint | gdlint | Lint GDScript 代码 | | Format | gdformat | 格式化/检查格式 | | Metrics | gdradon cc | 代码指标分析 | | Export | godot --export-pack | 导出验证 | | LSP Diagnostics | godot-lsp__diagnostics | 实时语法检查(通过 MCP) |

gdradon 输出

gdradon cc <path>

输出格式:

F <line>:<col> <function_name> - <grade> (<cc>)

| 字段 | 说明 | |------|------| | F | 函数 (Function) | | <line>:<col> | 行号和列号 | | <function_name> | 函数名 | | <grade> | 复杂度等级: A(简单), B(中等), C(复杂), D(非常复杂), F(极复杂) | | <cc> | 圈复杂度数值 |

示例:

.\character_body_2d.gd
    F 13:0 _physics_process - C (15)

使用示例

# Lint 检查
gdlint "D:/project/scripts/Player.gd"

# Format 检查
gdformat --check "D:/project/scripts/Player.gd"

# 代码指标
gdradon cc D:/project/scripts/

# LSP 诊断(DiagnosticsServer 为开机自启动服务)
# 调用 MCP 工具获取诊断(只需 uri 参数)
godot-lsp__diagnostics(uri="file:///D:/project/game/player.gd")

# LSP 诊断(修改代码后使用 refresh=true)
godot-lsp__diagnostics(uri="file:///D:/project/game/player.gd", refresh=true)

# 完整检查
gdlint D:/project/scripts/ && gdformat D:/project/scripts/ && gdradon cc D:/project/scripts/

# 导出验证
godot --headless --path "D:/project" --export-pack "Web" "D:/export.pck"

LSP Diagnostics

Godot LSP 诊断提供实时的语法检查和错误检测,与 Godot 编辑器显示的诊断一致。

前置条件

  1. Godot 编辑器运行(Godot LSP 服务器在编辑器启动时自动开启,默认端口 6005)
  2. DiagnosticsServer 运行(开机自启动服务,提供诊断缓存)

MCP 工具调用

工具名: godot-lsp__diagnostics

参数:

  • uri (必需): file:// URI,例如 file:///D:/project/game/player.gd
  • refresh (可选): 是否强制刷新诊断缓存,默认 false

返回:

{
  "uri": "file:///D:/project/game/player.gd",
  "diagnostics": [
    {
      "range": { "start": { "line": 4, "character": 0 }, "end": { "line": 4, "character": 56 } },
      "severity": 2,
      "code": 9,
      "source": "gdscript",
      "message": "(SHADOWED_GLOBAL_IDENTIFIER): The constant \"AttackType\" has the same name as a global class..."
    }
  ],
  "cached": false  // true 表示从缓存返回,false 表示新打开文件
}

说明:

  • DiagnosticsServer 会自动读取文件内容,无需传递 text 参数
  • 首次查询会打开文件并等待诊断(约 500ms)
  • 后续查询直接从缓存返回,速度更快
  • 修改代码后推荐使用 refresh=true 强制刷新缓存,确保获取最新诊断结果

诊断级别 (severity)

| 级别 | 值 | 说明 | |------|-----|------| | Error | 1 | 错误,必须修复 | | Warning | 2 | 警告,建议修复 | | Information | 3 | 信息 | | Hint | 4 | 提示 |

常见诊断代码

| 代码 | 消息 | 说明 | |------|------|------| | 1 | PARSER_ERROR | 语法错误 | | 9 | SHADOWED_GLOBAL_IDENTIFIER | 常量名与全局类冲突 | | 12 | STATIC_VARIABLE_TYPE_MISMATCH | 静态变量类型不匹配 | | 21 | RETURN_VALUE_DISCARDED | 返回值未使用 | | 30 | UNSAFE_CALL | 不安全的函数调用 | | 40 | UNASSIGNED_VARIABLE_ACCESS | 访问未赋值的变量 |

HTTP API(直接访问 DiagnosticsServer)

# 获取诊断
curl "http://127.0.0.1:3457/diagnostics?path=D:/project/game/player.gd"

# 刷新诊断
curl -X POST "http://127.0.0.1:3457/refresh" -d "{\"path\":\"D:/project/game/player.gd\"}"

# 查看状态
curl "http://127.0.0.1:3457/stats"

与 gdlint 对比

| 特性 | LSP Diagnostics | gdlint | |------|----------------|--------| | 实时性 | 实时(缓存) | 需要运行 | | 错误类型 | 语法 + 语义 | Lint 规则 | | 与编辑器一致 | 完全一致 | 可能不同 | | 速度 | 快(有缓存) | 慢(需解析) | | 需要 Godot | 是 | 否 |

建议: 使用 LSP Diagnostics 作为快速检查,gdlint 作为补充 lint 规则检查。

Lint Rules (gdlint)

| Rule | Severity | Description | |------|----------|-------------| | unused-variable | Error | Variable declared but never used | | shadowed-variable | Error | Variable shadows member variable | | function-name | Error | Function name violates naming convention | | constant-name | Error | Constant name violates naming convention | | trailing-whitespace | Warning | Lines have trailing whitespace | | missing-docstring | Warning | Function missing documentation | | line-too-long | Warning | Line exceeds 120 characters |

Error Handling

| Error | Solution | |-------|----------| | No project.godot found | Navigate to project root or provide absolute path | | gdlint not found | Install: pip install gdtoolkit | | gdradon not found | Install: pip install gdradon | | godot not found | Add godot to PATH | | Path must be absolute | Convert relative to absolute paths |

Common Workflows

After Code Changes

gdlint "D:/project/scripts/Player.gd"

Pre-commit Validation

gdlint D:/project/scripts/ && gdformat D:/project/scripts/

Code Metrics Analysis

gdradon cc D:/project/scripts/

输出示例:

.\character_body_2d.gd
    F 13:0 _physics_process - C (15)

Export Validation

godot --headless --path "D:/project" --export-pack "Web" "D:/export.pck"

安装要求

  • pip install gdtoolkit (gdlint, gdformat)
  • pip install gdradon (code metrics)
  • godot in PATH (export validation)

Tips

  • Use file param to check only changed files (faster)
  • gdformat --check shows what would change without modifying
  • gdradon cc shows complexity and maintainability metrics
  • Export validation catches dependency issues lint misses
