@michaelfiber thanks for providing the script! I actually had a similar implementation in C that I used for latest release but it's not published. I prefer to keep this script out of raylib src directory but not sure where it should be placed, maybe In any case, an action would be required to build examples on change and update EDIT: Just a reminder that required action should run on Linux server. |
