This is a portable C interpreter (and compiler) based on tinycc and capable of executing C code as-is at runtime, without a build step. It also supports a curated selection of functions from included libraries.
When using CJIT there is no need for any toolchain, library, headers or other files, only its executable interpreter is needed.
The idea of JIT compilation and execution for a C-like language is inspired by Terry Davis, the author of TempleOS, and Fabrice Bellard, the author of FFMpeg and TinyCC, whose in-memory compiler implementation is used inside CJIT.
We provide ready to execute binary builds as releases on github.
Paste this into your terminal
curl -sLo cjit https://github.com/dyne/cjit/releases/latest/download/cjit
chmod +x cjit
cat << EOF > hello.c
#!./cjit
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char **argv) {
fprintf(stderr,"Hello, World!\n");
exit(0);
}
EOF
./cjit hello.cYou can now play around with hello.c and write your own C code, which can be simply executed with this command:
./cjit hello.c
On GNU+Linux systems make sure to have installed:
musl musl-dev musl-tools
This is the first target chosen for development, others will come soon with different build-time dependencies: mingw cross, dynamic executable, etc.
