UnitGen 是一个用于生成微调代码的数据框架 —— 直接从你的代码库中生成微调数据：代码补全、测试生成、文档生成等。

Finetune Model Examples:

Language support by Chapi

• supported:
  • Java
  • Kotlin
• doing:
  • TypeScript/JavaScript
  • Rust
• future:
  • Go
  • Python
  • C/C++
  • C#
  • Scala

Features:

• Code context strategy: Related code completion, Similar Code Completion
• Instruction Builder type: inline, block, after block, documentation, test gen
• Code quality filter and pipeline. Code smell, test smell, estimation and more.

Layered Architecture

Workflow

• Unique prompt. Integrated use of fine-tuning, evaluation, and tooling.
• Code quality pipeline. With estimate with code complex, bad smell, test bad smell, and more rules.
• Extendable customize quality thresholds. Custom rules, custom thresholds, custom quality type or more.

Keep the same prompt: AutoDev <-> UnitGen <-> UnitEval

AutoDev prompt template example:

Write unit test for following code.

${context.coc}

${context.framework}

${context.related_model}

```${context.language}
${context.selection}
```

Unit Picker prompt should keep the same structure as the AutoDev prompt. Prompt example:

Instruction(
    instruction = "Complete ${it.language} code, return rest code, no explaining",
    output = it.output,
    input = """
    |```${it.language}
    |${it.relatedCode}
    |```
    |
    |Code:
    |```${it.language}
    |${it.beforeCursor}
    |```""".trimMargin()
)

UnitGen prompt should keep the same structure as the AutoDev prompt. Prompt example:

Complete ${language} code, return rest code, no explaining

```${language}
${relatedCode}
```

Code:
```${language}
${beforeCursor}
```

Optional quality type:

enum class CodeQualityType {
    BadSmell,
    TestBadSmell,
    JavaController,
    JavaRepository,
    JavaService,
}

Custom thresholds' config:

data class BsThresholds(
    val bsLongParasLength: Int = 5,
    val bsIfSwitchLength: Int = 8,
    val bsLargeLength: Int = 20,
    val bsMethodLength: Int = 30,
    val bsIfLinesLength: Int = 3,
)

Custom rules:

val apis = apiAnalyser.toContainerServices()
val ruleset = RuleSet(
    RuleType.SQL_SMELL,
    "normal",
    UnknownColumnSizeRule(),
    LimitTableNameLengthRule()
    // more rules
)

val issues = WebApiRuleVisitor(apis).visitor(listOf(ruleset))
// if issues are not empty, then the code has bad smell

for examples, see: examples folder

see in config-examples

download the latest version from GitHub Release

1. config project by processor.yml
2. run picker: java -jar unit-gen.jar

see in config-example

1.add dependency

dependencies {
    implementation("cc.unitmesh:unit-picker:0.1.5")
    implementation("cc.unitmesh:code-quality:0.1.5")
}

2.config the unit-gen.yml file and connection.yml

3.write code

public class App {
    public static void main(String[] args) {
        List<InstructionType> builderTypes = new ArrayList<>();
        builderTypes.add(InstructionType.RELATED_CODE_COMPLETION);

        List<CodeQualityType> codeQualityTypes = new ArrayList<>();
        codeQualityTypes.add(CodeQualityType.BadSmell);
        codeQualityTypes.add(CodeQualityType.JavaService);

        PickerOption pickerOption = new PickerOption(
                "https://github.com/unit-mesh/unit-gen-testing", "master", "java",
                ".", builderTypes, codeQualityTypes, new BuilderConfig()
        );

        SimpleCodePicker simpleCodePicker = new SimpleCodePicker(pickerOption);
        List<Instruction> output = simpleCodePicker.blockingExecute();

        // handle output in here
    }
}
