Quick Start

D:\> gem install raylib-bindings
Fetching raylib-bindings-...
...
1 gem installed

D:\> ruby -r raylib -e 'Raylib.template'
[Info] Raylib.template : C:/Ruby31-x64/lib/ruby/gems/3.1.0/gems/raylib-bindings-0.0.11/examples/template.rb => d://template.rb

Example Smoke Test

Run curated examples one by one for a short duration, terminate them, and report status:

# cross-platform
ruby script/examples_smoke_test.rb

# Windows helper
script\examples_smoke_test.cmd

# POSIX helper
sh script/examples_smoke_test.sh

Options:

--timeout 5 : per-example runtime in seconds before termination
--allowlist examples/smoke_allowlist.txt : explicit list of runnable examples
--list : print resolved allowlist and exit
--verbose : print execution details and child output on failures

Exit code policy:

0 when all examples either exit successfully or are timeout-terminated
non-zero when any example fails to spawn or exits with non-zero status before timeout

Limitation

SetTraceLogCallback and TraceLogCallback are unusable since Ruby-FFI does not support :varargs parameter in callbacks (Proc, etc.)
- Ref.: https://ffi.github.io/ruby-ffi-archive/messages/20130214-%5Bruby-ffi%5D%20Re_%20Callback%20Function%20with%20varargs-345.html
For macOS users: if you get error messages like “'.... .dylib' not valid for use in process: library load disallowed by system policy” , you can work around it with the following command (although it is not recommended):
- $ xattr -dr com.apple.quarantine (path to the .dylib)
