You can now: * `make qemu` to run it in QEMU user-mode emulation * `make run` to run it directly, if you are actually on RISC-V Try typing some simple Fiveth programs. Outputs are shown after a semicolon. ``` 0 > 1 2 + . ; 3 0 > 10 [ . ] count ; 0 1 2 3 4 5 6 7 8 9 0 > "Hello, world!" s. ; Hello, world! ``` Press Ctrl-D to quit. [`docs/shell.md`](/dramforever/fiveth/blob/main/docs/shell.md) has more details on running and using the Fiveth interactive shell. ## Installing the required tools On Ubuntu 22.04: ``` # apt install qemu-user make # # If using GNU toolchain # apt install gcc-riscv64-linux-gnu # # If using LLVM toolchain # apt install clang lld ``` If you have Nix, you can try to use the provided `shell.nix` or `flake.nix`. On other systems, you can try to acquire a LLVM toolchain or a RISC-V toolchain, as well as GNU make. To run Fiveth in an emulator, `qemu-riscv64` can be used to emulate a Linux binary but is only supported on Linux hosts. ## About A stack-based language implemented in RISC-V assembly ### Topics [assembly](/topics/assembly "Topic: assembly") [riscv](/topics/riscv "Topic: riscv") [forth-like](/topics/forth-like "Topic: forth-like") ### Resources [Readme](#readme-ov-file) ### Uh oh!
