How to implement a programming language (tutorial for beginners)

Programmer in SF, currently working on the Pinecone programming language, among other projects Mar 30, I wrote a programming language. And yet, I still made a completely new language.

So I must be doing something right. Compiled vs Interpreted There are two major types of languages: Technically any language could be compiled or interpreted, but one or the other usually makes more sense for a specific language.

Generally, interpreting tends to be more flexible, while compiling tends to have higher performance. But this is only scratching the surface of a very complex topic. I highly value performance, and I saw a lack of programming languages that are both high performance and simplicity-oriented, so I went with compiled for Pinecone.

This was an important decision to make early on, because a lot of language design decisions are affected by it for example, static typing is a big benefit to compiled languages, but not so much for interpreted ones.

Despite the fact that Pinecone was designed with compiling in mind, it does have a fully functional interpreter which was the only way to run it for a while. There are a number of reasons for this, which I will explain later on.

If you plan to compile, a slower language like Python or JavaScript is more acceptable. That is, it has several stages. Each stage has data formatted in a specific, well defined way. It also has functions to transform data from each stage to the next.

The first stage is a string containing the entire input source file. The final stage is something that can be run.

This will all become clear as we go through the Pinecone pipeline step by step. Lexing The first step in most programming languages is lexing, or tokenizing. Tokens A token is a small unit of a language. A token might be a variable or function name AKA an identifieran operator or a number.

Future stages of the pipeline will not refer back to the original source code, so the lexer must produce all the information needed by them.

The reason for this relatively strict pipeline format is that the lexer may do tasks such as removing comments or detecting if something is a number or identifier.This C programming language compiler will be used to compile your source code into final executable program.

I assume you have basic knowledge about a programming language. Advanced compilers like gcc compile codes into machine readable files according to the language in which the code has been written (e.g. C, C++, etc).

In fact, they interpret the meaning of each codes according to library and functions of the corresponding languages.

Not surprisingly, the opaqueness of these books has led to the myth that compilers are hard to write.

The best source for breaking this myth is Jack Crenshaw's series, Let's Build a Compiler!, which started in This is one of those gems of technical writing where what's assumed to be a complex topic ends up being suitable for a first year programming class.

Local Environment Setup. If you want to set up your environment for C programming language, you need the following two software tools available on your computer, (a) Text Editor and (b) The C Compiler.

Learning to write a compiler. Hi Stack Overflow, now don't get me wrong, I don't intend to write a compiler for C++(though I intend to write it in C++) or Java or some .
