Guarding is a guardians for code, architecture, layered. Using git hooks and DSL for design guard rules.

Inspired by ArchUnit

1. install

cargo install guarding

2. create guarding.guarding file

package(".")::file.len should < 200;
package(".")::file.len should > 50;

3. run

guarding .

• guarding_adapter, FFI adapter, provide Guarding api,
• guarding_core, core guarding model,
• guarding_ident, identify different language: Java, JavaScript, Rust
• guarding_parser parsing Guarding DSL

workflow:

1. parsing guarding rules
2. parsing source code to models
3. capture rule with models

DSL capture logic:

1. filter models from rule_level with rule_scope
2. run expression
3. run assert

for packages:

class(implementation "BaseParser")::name should endsWith "Parser";
class("java.util.Map") only accessed(["com.phodal.pepper.refactor.staticclass"]);
class(implementation "BaseParser")::name should not contains "Lexer";

for Java, JavaScript

# 类::名 包含 "Controller";
# 中文分词：("..myapp..") 类名称中包含 "Controller"
class("..myapp..")::function.name should contains("Model");
# or
class("..myapp..")::function.name contains("");

for Rust and Golang

struct("..myapp..")::function.name should contains("Model");
# or
struct("..myapp..")::function.name contains("");
