A simple Static Hermes demo using DearImGUI

sh-gpt-scroller

This is a demo using Static Hermes to build a simple desktop GUI app based on DearImGUI.

Originally, this repository contained a simple canvas JS game generated by ChatGPT. That original source can be found in the original-js branch. The original game is now one of several windows in the app.

There is a C++ and JS version of the same app, for performance comparison purposes (the JS version has an extra window, but it can be disabled). The C++ version has sound effects, which can be disabled either by using the appropriate build configuration flag or by setting the NOSOUND environment variable.

Building

You need CMake and Ninja (or Make) to build the C++ version.

You need a fork of Static Hermes to build the JS version (we made some changes in SH for this demo, that we are not sure that we want to land in the official branch). The fork can be found at https://github.com/tmikov/hermes/tree/sh-gpt-scroller.

There are no other dependencies.

C++ Version for macOS

mkdir build
cd build
cmake .. -G Ninja -DSOLOUD_BACKEND_COREAUDIO=ON -DSOLOUD_BACKEND_SDL2=OFF
ninja demo

JS Version for macOS

Assuming you have the forked Static Hermes checked out in $HERMES_SRC and built in $HERMES_BUILD:

mkdir build
cd build
cmake .. -G Ninja -DSOLOUD_BACKEND_COREAUDIO=ON -DSOLOUD_BACKEND_SDL2=OFF \
  -DHERMES_BUILD=$HERMES_BUILD -DHERMES_SRC=$HERMES_SRC
ninja jsdemo
