NOTE: This is forked from https://sourceforge.net/projects/igcc/. I have done some refactoring and ported it to Python 3.7. I am currently maintaining it.
- Interactive GCC (igcc) is a read-eval-print loop (REPL) for C/C++
- A default
libigcc/boilerplate.hheader is included, with<bits/stdc++.h>,using namespace std;, and some helper functions - For configuration (mainly related to compiling) see
config.yaml
git clone https://github.com/alexandru-dinu/igcc.git
cd igcc
pip install -r requirements.txt
./igcc -I libigccThe code will be compiled with GCC and the results (if any) will be displayed.
Type .h for help:
[ 1] igcc> .h
.L List the whole program as given to the compiler
.e Show the last compile errors/warnings
.h Show this help message
.l List the code you have entered
.q Quit
.r Redo undone command
.u Undo previous command
Simple usage:
$ ./igcc -I libigcc
[ 1] igcc> int a = 5;
[ 2] igcc> a += 2;
[ 3] igcc> cout << a << endl;
7
[ 4] igcc> --a;
[ 5] igcc> cout << a << endl;
6
Include header files:
$ ./igcc -I libigcc
[ 1] igcc> #include <vector>
[ 2] igcc> vector<int> xs = {1,2,3};
[ 3] igcc> xs.push_back(17);
[ 4] igcc> xs.pop_back();
[ 5] igcc> printf("%u", xs.size());
3
Compile errors can be tolerated until the code works:
$ ./igcc
[ 1] igcc> for (int i = 0; i < 10; i++) {
Compile error - type .e to see it OR disregard if multi-line statement(s)
[ 2] igcc> cout << i << " ";
Compile error - type .e to see it OR disregard if multi-line statement(s)
[ 3] igcc> }
0 1 2 3 4 5 6 7 8 9
Libs can be linked:
$ ./igcc -I libigcc -lpthread
[ 1] igcc> #include <pthread.h>
[ 2] igcc> pthread_t thr;
[ 3] igcc> const char* msg = "Hello, World!";
[ 4] igcc> // assuming print_msg is defined somewhere
[ 5] igcc> int ret = pthread_create(&thr, NULL, print_msg, (void*) msg); pthread_join(thr, NULL);
Hello, World!
