Is there an interpreter for C? [closed]

问题:

I was wondering if there is something like an interpreter for C. That is, in a Linux terminal I can type in \"python\" and then code in that interpreter. (I\'m not sure interpreter the right word). This is really helpful for testing different things out and I\'m curious if something similar exists for C. Though I doubt it. The only thing I can think of that would do it would be the C shell...

回答1:

There are many - if you narrow down the scope of your question we might be able to suggest some specific to your needs.

A notable interpreter is \"Ch: A C/C++ Interpreter for Script Computing\" detailed in Dr. Dobbs:

Ch is a complete C interpreter that supports all language features and standard libraries of the ISO C90 Standard, but extends C with many high-level features such as string type and computational arrays as first-class objects.

Ch standard is freeware but not open source. Only Ch professional has the plotting capabilities and other features one might want.

I\'ve never looked at this before, but having a c interpreter on hand sounds very useful, and something I will likely add to my toolset. Thanks for the question!

Edit:

Just found out that one of my favorite compilers, TCC, will execute C scripts:

It also handles C script files (just add the shebang line \"#!/usr/local/bin/tcc -run\" to the first line of your C source code file on Linux to have it executed directly.

TCC can read C source code from standard input when \'-\' is used in place of \'infile\'. Example:

echo \'main(){puts(\"hello\");}\' | tcc -run -

picoc - A very small C interpreter

PicoC is a very small C interpreter for scripting. It was originally written as the script language for a UAV\'s on-board flight system. It\'s also very suitable for other robotic, embedded and non-embedded applications.

回答3:

the ROOT project provides a very functional C and C++ interpreter called Cint. I\'m quite fond of it. It takes a little getting used to interpretively, though.

TCC is a very good choice as well, but i\'m not able to vouch for its REPL

回答4:

Probably. There are several for c++. See Have you used any of the C++ interpreters (not compilers)? for examples. Certainly cint will eat nearly any c code with good results, and tcc is so fast that you can use it like a interpreter.

回答5:

Give a look to the Ch Interpreter.

Ch is an embeddable C/C++ interpreter for cross-platform scripting, shell programming, 2D/3D plotting, numerical computing, and embedded scripting.

回答6:

I know we use CINT in class. It seemed pretty good you might want to give it a try!

回答7:

Check Out iGCC

回答8:

cinterp is one for a start.

回答9:

ccons appears to satisfy your constraints:

The goal of the ccons project is to create an interactive console for the C programming language, similar to \"python\" and \"irb\" for Python and Ruby respectively. The project builds on top of clang and llvm.

回答10:

More recently there is Cling (based on LLVM/Clang)

回答11:

You can use CompCert. Here are some examples: http://compcert.inria.fr/man/manual004.html

回答12:

It has been done, even though the vast majority of C work is compiled. One example is CH

回答13:

CERN has a toolkit called ROOT, which is meant mainly for scientific or data analysis etc.. purposes but it has a Clang - based C/C++ Interpreter called Cling.

They were using a C interpreter called CINT before they adapted Cling. CINT is lightweight & still seems to be available for download.

I think you may get some other by carefully searching through Wikipedia list articles.
