TypeLite(二)-- 编写生成器

此文部分摘自Part II - Using TypeLite to Generate TypeScript

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

1. 创建C#控制台工程
2. 安装TypeLite库到此工程

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<Guid>(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);        }
