TypeLite(二)--编写生成器

TypeLite(二)--编写生成器。TypeLite默认使用T4编写模版,假如不想使用T4,可以创建一个控制台程序,并直接使用TypeLite的Api.

1. 创建工程

2. 修改Program.cs

using System;
using System.IO;
using System.Reflection;
using TypeLite;

namespace TypeScriptSample.Generator
{
    class Program
    {
        static void Main(string[] args)
        {
            var assemblyFile = args[0];
            var outputPath = args[1];

            LoadReferencedAssemblies(assemblyFile);
            GenerateTypeScriptContracts(assemblyFile, outputPath);
        }

        private static void LoadReferencedAssemblies(string assemblyFile)
        {
            var sourceAssemblyDirectory = Path.GetDirectoryName(assemblyFile);
            foreach (var file in Directory.GetFiles(sourceAssemblyDirectory, "*.dll"))
            {
                File.Copy(file, Path.Combine(AppDomain.CurrentDomain.BaseDirectory, new FileInfo(file).Name), true);
            }
        }

        private static void GenerateTypeScriptContracts(string assemblyFile, string outputPath)
        {
            var assembly = Assembly.LoadFrom(assemblyFile);
            // If you want a subset of classes from this assembly, filter them here
            var models = assembly.GetTypes();

            var generator = new TypeScriptFluent()
                .WithConvertor(c => "string");

            foreach (var model in models)
            {
                generator.ModelBuilder.Add(model);
            }

            //Generate enums
            var tsEnumDefinitions = generator.Generate(TsGeneratorOutput.Enums);
            File.WriteAllText(Path.Combine(outputPath, "enums.ts"), tsEnumDefinitions);
            //Generate interface definitions for all classes
            var tsClassDefinitions = generator.Generate(TsGeneratorOutput.Properties | TsGeneratorOutput.Fields);
            File.WriteAllText(Path.Combine(outputPath, "classes.d.ts"), tsClassDefinitions);

        }
    }
}

3. 运行

打开cmd

TypeScriptSample.Generator.exe ..\\..\\..\\TypeScriptSample.Models\\bin\\debug\\TypeScriptSample.Models.dll ..\\..\\..\\TypeScriptSample.Web\\App\\server

参数:
1. 第一个参数为需要提取typescript的dll
2. 第二个参数为输出文件夹

可以写成bat文件,在需要转换时运行
也可以添加到项目编译事件,在编译项目成功后,直接运行

4. 只提取添加注解的类

此程序会转化dll中所有的类,如只需提取添加[TsClass]注解的类,需修改
函数GenerateTypeScriptContracts为

 private static void GenerateTypeScriptContracts(string assemblyFile, string outputPath)
        {
            Assembly.LoadFrom(assemblyFile);

           var ts =  TypeScript.Definitions().ForLoadedAssemblies();

            ////Generate enums
            var tsEnumDefinitions = ts.Generate(TsGeneratorOutput.Enums);
            File.WriteAllText(Path.Combine(outputPath, "enums.ts"), tsEnumDefinitions);
            //Generate interface definitions for all classes
            var tsClassDefinitions = ts.Generate(TsGeneratorOutput.Properties | TsGeneratorOutput.Fields);
            File.WriteAllText(Path.Combine(outputPath, "classes.d.ts"), tsClassDefinitions);

        }
