Practical Foundations for Programming Languages , this is, for the most part, a book about studying and classifying programming languages.
But by understanding the different options available it can also be used to guide the implementation of your programming language. Programming Language Pragmatics, 4th Edition , this is the most comprehensive book to understand contemporary programming languages. It discusses different aspects, of everything from C to OCaml, and even the different kinds of programming languages such as functional and logical ones.
It also covers the several steps and parts of the implementation, such as an intermediate language, linking, virtual machines, etc. Structure and Interpretation of Computer Programs, Second Edition , an introduction to computer science for people that already have a degree in it. A book widely praised by programmers, including Paul Graham directly on the site Page , that helps you developing a new way to think about programming language.
Type Systems Long discussions and infinite disputes are fought around type systems. Whatever choices you end up making it make sense to know the different positions. Articles These are two good introductory articles on the subject of type systems. Type Systems PDF , a paper on the formalization of type systems that also introduces more precise definitions of the different type systems. Books Types and Programming Languages , a comprehensive book on understanding type systems.

It will impact your ability to design programming languages and compilers. It has a strong theoretical support, but it also explains the practical importance of individual concepts.
Functional programming and type systems , an interesting university course on type systems for functional programming. It is used in a well known French university. It is as advanced as you would expect. Type Systems for Programming Language , is a simpler course on type system for functional programming languages.
Section 2: Parsing Parsing transforms the concrete syntax in a form that is more easily manageable by computers. There are usually two components in parsing: a lexical analyzer and the proper parser. Lexers, which are also known as tokenizers or scanners, transform the individual characters in tokens, the atom of meaning. Parsers instead organize the tokens in the proper Abstract Syntax Tree for the program.
But since they are usually meant to work together you may use a single tool that does both the tasks. Tools Flex , as a lexer generator and Berkeley Yacc or Bison , for the generation of the proper parser, are the venerable choices to generate a complete parser.
They are a few decades old and they are still maintained as open source software. They still works, but they have limitations in features and support for other languages. ANTLR , is both a lexer and a parser generator. Your own lexer and parser.
If you need the best performance and you can create your own parser. You just need to have the necessary computer science knowledge.
Tutorials Flex and Bison tutorial , a good introduction to the two tools with bonus tips. Lex and Yacc Tutorial , at 40 pages this is the ideal starting point to learn how to put together lex and yacc in a few hours.
Some people say because the lack of competition, others because it is good enough. Parsing Techniques, 2nd edition , a comprehensive, advanced and costly book to know more than you possibly need about parsing. Section 3: Execution To implement your programming language, that is to say to actually making something happens, you can build one of two things: a compiler or an interpreter.
Here you can find a good overview if you need it: Compiled and Interpreted Languages.
Tools LLVM , a collection of modular and reusable compiler and toolchain technologies used to create compilers. CLR , is the virtual machine part of the. NET technologies, that permits to execute different languages transformed in a common intermediate language.
Programming Languages: Concepts and Constructs
Unlike low-level assembly languages , high-level languages have few, if any, language elements that translate directly into a machine's native opcodes. One thing to note about high-level programming languages is that these languages allow the programmer to be detached and separated from the machine. That is, unlike low-level languages like assembly or machine language, high-level programming can amplify the programmer's instructions and trigger a lot of data movements in the background without their knowledge.
The responsibility and power of executing instructions have been handed over to the machine from the programmer. Abstraction penalty[ edit ] High-level languages intend to provide features which standardize common tasks, permit rich debugging, and maintain architectural agnosticism; while low-level languages often produce more efficient code through optimization for a specific system architecture.
Abstraction penalty is the cost that high-level programming techniques pay for being unable to optimize performance or use certain hardware because they don't take advantage of certain low-level architectural resources.
High-level programming exhibits features like more generic data structures and operations, run-time interpretation, and intermediate code files; which often result in execution of far more operations than necessary, higher memory consumption, and larger binary program size. In many cases, critical portions of a program mostly in a high-level language can be hand-coded in assembly language , leading to a much faster, more efficient, or simply reliably functioning optimised program. However, with the growing complexity of modern microprocessor architectures, well-designed compilers for high-level languages frequently produce code comparable in efficiency to what most low-level programmers can produce by hand, and the higher abstraction may allow for more powerful techniques providing better overall results than their low-level counterparts in particular settings.
This facilitates executing a program written in such a language on any computing system with compatible support for the Interpreted or JIT program. High-level languages can be improved as their designers develop improvements. In other cases, new high-level languages evolve from one or more others with the goal of aggregating the most popular constructs with new or improved features.
An example of this is Scala which maintains backward compatibility with Java which means that programs and libraries written in Java will continue to be usable even if a programming shop switches to Scala; this makes the transition easier and the lifespan of such high-level coding indefinite.
In contrast, low-level programs rarely survive beyond the system architecture which they were written for without major revision. This is the engineering 'trade-off' for the 'Abstraction Penalty'. This section does not cite any sources. The terms high-level and low-level are inherently relative. Some decades ago, the C language , and similar languages, were most often considered "high-level", as it supported concepts such as expression evaluation, parameterised recursive functions, and data types and structures, while assembly language was considered "low-level".
Programming Languages: Concepts and Constructs
Today, many programmers might refer to C as low-level, as it lacks a large runtime -system no garbage collection, etc. It, therefore, readily blends with assembly language and the machine level of CPUs and microcontrollers. Assembly language may itself be regarded as a higher level but often still one-to-one if used without macros representation of machine code , as it supports concepts such as constants and limited expressions, sometimes even variables, procedures, and data structures.This is second in the series of articles for my niece Ahna.
An answer to How to write a very basic compiler , a good answer to the question that gives an overview of the steps needed and the options available to perform the task of building a compiler. In this case "some end condition is met" would refer to the whether we have repeated the same sequence of instructions or iterated 20 times or not.
