This is a really cool new language! Can it be used as a scripting language inside other software?

Please tell me this language can be embedded into other software!!

It would be perfect for things not decadent for python but way above lua's paygrade

Hi @the-LONS-network,

Yes. Blade can be embedded into other softwares. At it's core, the BVM and compiler are different entities from the complete Blade package. See src/blade.c for how its done.

Below is a simple integration:

#include <blade.h>
#include <stdlib.h>
#include <string.h>

int main() {

  const char * source = "echo 'It works'";

  // initialize the VM 
  b_vm *vm = (b_vm *) malloc(sizeof(b_vm));
  if (vm != NULL) {
    memset(vm, 0, sizeof(b_vm));
    init_vm(vm);

    // always do this before calling `repl` or `run_file`
    // this allows access to all the built-in functions.
    // NOTE: You can skip it if you don't need any of the 
    // built-in functions
    bind_native_modules(vm);

    // instantiate the base module (prefereably to an empty 
    // name to avoid conflicts with user defined module and 
    // packages.)
    b_obj_module *module = new_module(vm, "", "<std-file-path>");
    add_module(vm, module);

    interpret(vm, module, source);
  }

  return 0;
}

Don't forget to link libblade and add blade include directory to header source. For example, with clang, you can run:

export BLADE_ROOT=/your/blade/install/path
clang sample.c -I$BLADE_ROOT/includes -L$BLADE_ROOT/blade -lblade -o ./sample

If you are getting @rpath or $ORIGIN error while running the app on MacOS and Linux respectively, you might want to symbolic link the lib blade.dylib or lib blade.so respectively to the system library path. For example on OSX, I'll do something like:

sudo ln -s $BLADE_ROOT/libblade.dylib /usr/local/lib/libblade.dylib    # .so for Linux, .dylib for MacOS

I think I should add this to the documentation. :)
