Questions tagged [interpreted-language]

Questions about interpreted languages and program interpretation in general. A language implementation is interpreted if programs are executed by another program (the interpreter) as opposed to being transformed (compiled) into code that is directly executed by the machine.

An interpreted language is a programming language in which programs are "indirectly" executed (interpreted) by an interpreter program. This can be contrasted with a compiled language which is converted into machine code and then "directly" executed by the host CPU.

Theoretically, any language may be compiled or interpreted; this designation is applied purely because of common implementation practice and not some essential property of a language. Indeed, for some programming languages, there is little performance difference between an interpretive, or compiled-based approach to their implementation.

For more information, see the Wikipedia entry about interpreted languages.

Can you do "builds" with PHP scripts or an interpreted language?

Correct me if I'm wrong, but a "build" is a "compile", and not every language compiles. Continuous Integration involves building components to see if they continue to work beyond unit tests, which I might be oversimplifying. But if your project…

Is there any interpreted language exposing its bytecode (or any IR)

I'm curious to know if any language exists that gives the programmer the possibility to 'emit' bytecode in the middle of the source code. To be more clear, is there any interpreted language that has a facility similar to the asm keyword for c/c++ ? …
