Interpretation usually involves processing (analyzing and executing) the program one statement at a time. Interpretation takes as input the source program and its input, and produces the source program's output source program, input -> | interpreter | -> output If the target language is machine code, it can be executed directly on some processor: input -> | target program | -> outputĬompilation involves scanning and translating the entire input program (or module) and does not involve executing it. source program -> | compiler | -> target program The two basic mechanisms for processing a program are compilation and interpretation.Ĭompilation takes as input a source program in a given language and outputs a target program in a target language. The summary I give below is based on "Compilers, Principles, Techniques, & Tools", Aho, Lam, Sethi, Ullman, (Pearson International Edition, 2007), pages 1, 2, with the addition of some ideas of my own. ![]() So an interpreter doesn't produce machine language, but does a compiler do it for its input?ĭo I have any misunderstandings in the basic way how compilers and interpreters work? Would a compiler create machine language which runs on the physical hardware directly? and execute the foobish-language in the way of the interpreter's implementation. On a very easy interpreter level, the interpreter would analyze the script-file, etc. Now I write an interpreter in the language of my choice - C# in this case: using System ĪnalyseAndTokenize(Hello World.foobish-file)//Pseudocode So if I want to print to the console 10 times, I would write OUTPUT 'Hello World', 10 I have a language called "Foobish" and its keywords are 'TEXT', I want to check if my base understanding is right, so let's assume the following: I study the topics of compilers and interpreters intensively. ![]()
