Interactive C/C++ interpreter on Fedora?

CD-RW · #1 2009-10-29, 10:09 AM CDT

Is there a C/C++ interpreter similar to PHP, Python, Ruby etc, that I can use to run C programs a line at a time, without compiling the C code?

Does Fedora 8+ come with anything like this in the repos?

TIA

Because C and C++ are compiled languages unlike PHP etc, not really. What you can do is to run the code in a debugger, GDB for example, to see what happens, where and when.

There is one called Ch that interprets C, but it doesn't support C++ IIRC. It's not really the best idea in my opinion though. If you are doing something where compiling a program is annoying, having to use C at all will be *way* more annoying.

What are you actually trying to do?

Maybe he just wants to learn about C but don't want to go over the make - run - break - edit - make stuff over and over again. Being able to see the disastrous results at once is sometimes considered a virtue. run - break - run - break - run - break - run - win.

All I want to do is to run small examples of C code in an interpreted environment, to save doing the compile, link and run stuff.

I've seen the Ch website. There is also this one here:

Cint: http://root.cern.ch/drupal/content/cint

I was wondering if they or something similar was packaged for Fedora 8+?

Save me the trouble of compiling and messing with the source code.

Note: I'm using Eclipse and CDT for compiling and debugging C/C++ code, which is brilliant. However, it seems overkill to start Eclipse, and create a project just to test a few lines of C code.

Yeah, that's what this is good for:

Code:

g++ test.cpp -o test

./test

If you want, you can alias these commands which do roughly what you would expect from an interpreter:

Code:

cat > tobeinterpreted.cpp << EOF && gcc tobeinterpreted.cpp -o tobeinterpreted && ./tobeinterpreted;rm tobeinterpreted.cpp

Just start typing the file and put "EOF" on its own line to exit editing mode and start compiling.

I don't believe that's what the OP wanted. Not interactively enough.

I just use three windows - one for edits, one for compile, one for execute/debug.

That way any compile errors (with line numbers) are immediately accessible, and can be correlated with the
source.

Cool, I never knew there was such a thing. This is helpful. I use something similar for Java.

Here's the homepage for Ch:

http://www.softintegration.com/

Ch is an embeddable C/C++ interpreter for cross-platform scripting, shell programming, 2D/3D plotting, numerical computing, and embedded scripting. Ch is a free and user-friendly alternative to C/C++ compilers for beginners to learn C/C++. Ch is the solution for:

* Embedded Scripting
* Enterprise
* Academic
* Numerical Computing
* Web-Based Computing

Nice to have this or CINT packaged with Fedora

Both would be even better - LOL
