我同意龙书的参考;IMO，它是编译器构造的权威指南。准备好接受一些核心理论吧。

If you want a book that is lighter on theory, Game Scripting Mastery might be a better book for you. If you are a total newbie at compiler theory, it provides a gentler introduction. It doesn't cover more practical parsing methods (opting for non-predictive recursive descent without discussing LL or LR parsing), and as I recall, it doesn't even discuss any sort of optimization theory. Plus, instead of compiling to machine code, it compiles to a bytecode that is supposed to run on a VM that you also write.

这仍然是一本不错的读物，尤其是如果你能在亚马逊上以便宜的价格买到的话。如果你只想简单介绍编译器，《Game Scripting Mastery》是个不错的选择。如果你想先玩硬核游戏，那么你应该选择《龙之书》。

“让我们构建一个编译器”是很棒的，但它有点过时了。(我并不是说这让它变得不那么有效。)

或者看看俚语。这类似于“让我们构建一个编译器”，但对于初学者来说是一个更好的资源。这是一个pdf教程，需要7步的方法来教你一个编译器。添加quora链接，因为它有各种各样的俚语端口的链接，在c++， Java和JS中，也有python和Java中的解释器，最初是用c#和。net平台编写的。

创建编译器的一个简单方法是使用bison和flex(或类似)，构建一个树(AST)并用C生成代码，生成C代码是最重要的步骤。通过生成C代码，您的语言将自动在所有具有C编译器的平台上运行。

生成C代码就像生成HTML一样简单(只需使用打印或等效工具)，这又比编写C解析器或HTML解析器容易得多。

我认为这是一个相当模糊的问题;只是因为这个话题涉及的深度。然而，编译器可以被分解成两个独立的部分;上半身和下半身。上半部分通常采用源语言并将其转换为中间表示，下半部分负责特定于平台的代码生成。

尽管如此，解决这个问题的一个简单方法(至少是我们在编译器类中使用的方法)是在上面描述的两部分中构建编译器。具体来说，通过构建上半部分，您将对整个过程有一个很好的了解。

Just doing the top half lets you get the experience of writing the lexical analyzer and the parser and go to generating some "code" (that intermediate representation I mentioned). So it will take your source program and convert it to another representation and do some optimization (if you want), which is the heart of a compiler. The bottom half will then take that intermediate representation and generate the bytes needed to run the program on a specific architecture. For example, the the bottom half will take your intermediate representation and generate a PE executable.

关于这个主题的一些书，我发现特别有用的是编译器原理和技术(或者龙书，因为封面上有可爱的龙)。它有一些很棒的理论，而且肯定以一种非常容易理解的方式涵盖了上下文无关语法。此外，为了构建词法分析器和解析器，您可能会使用*nix工具lex和yacc。而且很无趣的是，这本名为《莱科斯和雅克》的书继承了《龙之书》这部分的内容。

如果您愿意使用LLVM，请查看这个:http://llvm.org/docs/tutorial/。它教你如何使用LLVM的框架从头编写编译器，并且不假设你有任何关于这个主题的知识。

本教程建议您编写自己的解析器和lexer等，但我建议您了解bison和flex后再进行研究。它们让生活变得轻松多了。

The Dragon Book is too complicated. So ignore it as a starting point. It is good and makes you think a lot once you already have a starting point, but for starters, perhaps you should simply try to write an math/logical expression evaluator using RD, LL or LR parsing techniques with everything (lexing/parsing) written by hand in perhaps C/Java. This is interesting in itself and gives you an idea of the problems involved in a compiler. Then you can jump in to your own DSL using some scripting language (since processing text is usually easier in these) and like someone said, generate code in either the scripting language itself or C. You should probably use flex/bison/antlr etc to do the lexing/parsing if you are going to do it in c/java.
