Notes on using JavaScript Promises in ReasonML/BuckleScript
/**
* Making promises
*/
let okPromise = Js.Promise.make((~resolve, ~reject as _) => [@bs] resolve("ok"));
/* Simpler promise creation for static values */
Js.Promise.resolve("easy");
Js.Promise.reject(Invalid_argument("too easy"));

How to debug Zig tests in VSCode

Tested on macOS:

  1. Install the CodeLLDB VSCode extension. Unlike the debugger in the C/C++ extension, this allows to set breakpoints inside Zig "test" blocks (in the MS C/C++ extension debugger, breakpoints inside test blocks will be disabled once the debugger starts for unknown reasons.
  2. When compiling the test, tell it to also emit a binary: zig test -femit-bin=zig-out/bin/my-test src/bla.zig, otherwise there will be no executable to debug.
  3. The compiled test executable expects the path to the Zig executable as first command line argument, the launch.json file needs to be setup accordingly (note the args item):

Compiling x86_64 assembly program on M1 Mac

If you have an M1 Mac and want to compile and execute x86_64 assembly code, make sure you install Rosetta 2 and nasm (brew install nasm).

Than, take a 64 Bit assembly program, e.g. from this tutorial page (https://cs.lmu.edu/~ray/notes/nasmtutorial/) in Section "Your First Program" for macOS, save it to a file called hello.asm.

Compile, link and execute the program:

nasm -f macho64 hello.asm
ld hello.o -o hello -macosx_version_min 11.0 -L /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib -lSystem

./hello
