"replay-based" REPL for compiled languages
Interactive REPL for executable-based software toolchains.
Ever wished you could have an interpreter for your executable-based compiled language toolchains? reple simulates an interpreter to create a REPL for you. Each time you enter a command, reple compiles and runs your program, printing out any new input.
The advantage to this approach is that reple only requires a simple config file to create a REPL for a new language or executable-based runtime system. If your language or runtime system is not available, adding it will likely only take a few minutes!
Just install the
reple pip package.
[xiii@reple ~]$ pip3 install reple [xiii@reple ~]$ reple.py -env cxx > printf("Hello, World!\n"); Hello, World!
If you install the package locally, you might need to add
~/.local/bin to your path.
To start an interactive REPL session, call
reple.py with the title of a configuration
file defined in the
[xiii@reple xiii]$ reple.py -env cxx > printf("Hello, world!\n"); Hello, world! > int x = 12; > int y = x + 2; > std::cout << y << std::endl; 14 >
Some more complicated runtimes, like MPI, may have optional runtime flags.
[xiii@reple home]$ reple.py -env mpicxx --rargs "-n 8" > int rank, nprocs; > MPI_Comm_rank(MPI_COMM_WORLD, &rank); > MPI_Comm_size(MPI_COMM_WORLD, &nprocs); > printf("Hello, world! I'm %d/%d\n", rank, nprocs); Hello, world! I'm 0/8 Hello, world! I'm 1/8 Hello, world! I'm 2/8 Hello, world! I'm 4/8 Hello, world! I'm 6/8 Hello, world! I'm 3/8 Hello, world! I'm 5/8 Hello, world! I'm 7/8 >
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
