C-Toy is an interactive C(99) coding environment based on TCC.

Overview

C-Toy

C-Toy is an interactive C(99) coding environment based on TCC.

Small, simple, no bullshit. Write cross-platform C code and see the result immediately. No installation or compiler required, download (<4mb), unzip, run CToy and play. Ready for Windows, MacOSX and Linux. Ideal for prototyping, learning, teaching...

Features

  • CToy: program update on file save (use any text editor)
  • CToy_player: to publish your project (dynamic update disabled)
  • API for window managment, inputs, persistent memory...
  • Image processing with MaratisTCL
  • OpenGLES-2
  • OpenAL
  • Portable pen-tablet support (Wacom, etc)
  • Use C-symbols from native dynamic libraries (*.dll etc) : just copy libraries in your_ctoy_path/lib/
  • Pre-built Dear-Imgui suport (https://github.com/ocornut/imgui)
  • Can also compile your project with other compilers (CMake script for gcc, vs, mingw)
  • Emscripten compatible

Download

- CToy 1.06 Win64
- CToy 1.05 MacOSX
- CToy 1.05 Linux64
- [all versions]

Requirement For Linux: OpenAL

Getting started

  • Launch CToy
  • Open src/main.c using your favorite text editor
  • Start coding (samples included)
  • Save your file(s) and see the result in realtime

Usage

C-Toy expects a main file in src/main.c.
But instead of the standad C "main" function, the entry points are "ctoy_begin", "ctoy_main_loop" and "ctoy_end".

The compulsory "Hello, World!" program is then (in src/main.c):

#include <ctoy.h> // ctoy API (including frequently used ANSI C libs)

void ctoy_begin() // called at the beginning of the program
{
   printf("Hello, World!\n");
}

void ctoy_main_loop() // called at every update of the main loop
{}

void ctoy_end() // called at the end of the program
{}

Every time you modify src/main.c or any other file connected to it (directly or recursively included), C-Toy will recompile and restart the program dynamically.

One other difference with standard C is the use of persistent memory to maintain a bloc of memory intact between recompiles. For example:

#include <ctoy.h>

void *persistent_memory = NULL;

void ctoy_begin()
{
   if (ctoy_t() == 0) {
      persistent_memory = calloc(256, 1); // allocate 256 bytes with zero value
      ctoy_register_memory(persistent_memory); // register persistent memory
   }
   else {
      persistent_memory = ctoy_retrieve_memory(); // retrieve persistent memory
   }
}

void ctoy_main_loop()
{
   int *persistent_counter = (int *)persistent_memory; // access a piece of persistent memory
   (*persistent_counter)++; // do something with the data
   printf("persistent_counter = %d\n", (*persistent_counter)); // print the content
}

void ctoy_end()
{}

(You can store any data that was manually allocated with malloc, it can be an array or a global pointer. Just avoid storing function pointers, as functions addresses may change after recompiles, or update them after calling ctoy_retrieve_memory)

    CToy crashes with SIGSEGV from libpthead.so, Arch Linux

    This wasn't an isssue on my machine with Ubuntu, but my laptop with Arch Linux. It's only relevant for the CToy executable. CToy_player does work, which makes sense because it doesn't compile with the thread stuff. What is the idea behind these two executables, CToy and CToy_player?

    I upgraded my entire system, and I still get the error, meaning that this fails with libpthread version 2.25 and 2.26.

    Thread 1 "CToy" received signal SIGSEGV, Segmentation fault. 0x00007ffff768d29e in pthread_join () from /usr/lib/libpthread.so.0 (gdb) bt #0 0x00007ffff768d29e in pthread_join () from /usr/lib/libpthread.so.0 #1 0x000000000047b7f1 in thrd_join () #2 0x0000000000464cbf in ctoy.src_thread_restart () #3 0x000000000043c579 in main ()

  • Compiling on Linux, GLFW Question

    Compiling on Linux, GLFW Question

    Hey,

    I've been working on getting this to work on my Linux machine and I had linker issues with the GLFW you had bundled with it. I replaced it with https://github.com/glfw/glfw, and I got past those issues.

    Your GLFW directory has less stuff than the original. Is it because you got it from a fork, and if so could you give me a link? Or is it something you cleaned up yourself, in which case could you tell me what stuff I should cut out?

    UPDATE: CToy is now compiling & running on my Linux machine

    Why is this only available on 64-bit OS? I don't have any 64-bit PC at hand at the moment, so a port to 32-bit will make me happy. I have had enough with two other free fantasy consoles being only on 64-bit and not having a 32-bit release.

    I'm uncertain if the Github issue tracker should be used like this, but it does seem the most convenient for me.

    I'm writing some code with CToy that compiles C files, which it then runs. Similar to one of your samples. I'm getting the following errors about repetition, and I'm wondering if you recognise which part I'm missing?

    Complete quoting for parameters of some CMake commands

    Some parameters (like "${MTCL_SOURCE_DIR}/3rdparty/glfw/include") are passed to CMake commands in your build scripts without enclosing them by quotation marks. I see that these places will result in build difficulties if the contents of the used variables will contain special characters like semicolons.

    I would recommend to apply advices from a wiki article.

    Consider replacing OpenAL by mini_al

    My experience: after more than 4 years using OpenAL for raylib, just switched to mini_al library.

    It's small, single-file header-only, multiplatform and removed the need of distributing OpenAL32.dll with your programs. I think it can make CToy a more self-contained product.
