added Brainflow SpO2 example

[jaketheduque]

Description

The Brainflow SpO2 algorithm has been added as an example alongside Rounder and EmotiBit Packet. This example is referenced by Validation Methods as a starting point for how to configure C++ algorithms to be compiled into a Python module.

The example itself points to the pybind directory of the EmotiBit Brainflow SpO2 Algorithm repo.

Notes for Reviewer

• Any references to anaconda environment have been replaced in lieu of Python venv
• Adapting this to your C++ code section has been moved to ahead of Examples
• Changes to example CMake commands so that user does not have to mkdir and cd into build directory
• BrainFlow SpO2 Algorithm example has been added. The section only points to the EmotiBit Brainflow SpO2 Algorithm repository for single-source-of-truth

Testing

Testing is performed in the EmotiBit Brainflow SpO2 Algorithm repo

@jaketheduque I've completed a comprehensive code review of the PR. Here are my findings:

✅ Positive Changes

1. Good Documentation Structure: The README_py.md is well-organized with clear sections and a helpful table of contents.

2. Simplified Build Process: The CMake commands have been improved to use -B build and --build build --config Release, eliminating the need for manual directory creation.

3. Proper Section Organization: The "Adapting this to your C++ code" section has been moved ahead of "Examples" as intended, improving the documentation flow.

4. Clean Python Examples: The Python example scripts demonstrate good practices with proper path handling and argument parsing.

5. Proper pybind11 Bindings: The binding files follow pybind11 conventions correctly.

⚠️ Issues Requiring Attention

Critical Issues:

1. Cross-Platform Compatibility Problem:

   set(pybind11_DIR "${CMAKE_CURRENT_SOURCE_DIR}\\..\\py_envs\\emotibit_plugins\\Lib\\site-packages\\pybind11\\share\\cmake\\pybind11")

   • Uses Windows-style backslashes that won't work on macOS/Linux
   • Should use forward slashes or CMAKE_PATH separators

2. Environment Name Inconsistency:

   • CMakeLists.txt references emotibit_plugins environment
   • README_py.md instructs users to create plugins environment
   • This will cause build failures when users follow the README

Moderate Issues:

3. Hardcoded Paths: The pybind11_DIR path is absolute and assumes a specific directory structure that may not exist on all systems.

4. Missing Error Handling: No validation for missing dependencies or incorrect environment setup.

5. Corrupted Configuration File: The EmotiBit-pyenv-modern.yml file appears to have encoding issues and may not be usable.

📋 Recommendations

Fix Cross-Platform CMakeLists.txt:

# Use cross-platform path handling
if(WIN32)
    set(pybind11_DIR "${CMAKE_CURRENT_SOURCE_DIR}/../py_envs/plugins/Lib/site-packages/pybind11/share/cmake/pybind11")
else()
    set(pybind11_DIR "${CMAKE_CURRENT_SOURCE_DIR}/../py_envs/plugins/lib/python*/site-packages/pybind11/share/cmake/pybind11")
endif()

Standardize Environment Name:

Either update CMakeLists.txt to use plugins or update README_py.md to use emotibit_plugins consistently.

Add Error Handling:

if(NOT EXISTS ${pybind11_DIR})
    message(FATAL_ERROR "pybind11 not found. Please ensure the Python virtual environment is set up correctly.")
endif()

🎯 PR Objectives Assessment

• ✅ Anaconda references replaced with Python venv
• ✅ "Adapting this to your C++ code" section moved ahead of Examples
• ✅ CMake commands simplified
• ✅ Brainflow SpO2 Algorithm example added with proper external reference
• ❌ Cross-platform compatibility needs addressing
• ❌ Environment naming consistency needs fixing

Overall, this is a solid improvement to the documentation and examples, but the cross-platform issues should be resolved before merging to ensure all users can successfully follow the instructions.

The code review has been completed and posted above. I've examined all the files in the repository, including the README documentation, CMakeLists.txt configurations, Python bindings, example scripts, and source code implementations.

The key findings focus on cross-platform compatibility issues in the CMakeLists.txt files and environment naming inconsistencies that could prevent users from successfully building the examples. While the core implementation and documentation improvements are solid, addressing these issues will ensure a smooth experience for all users across different operating systems.

+- `cd` to `EmotiBit_Plugins/py_envs`
-- Run the following command `python -m venv plugins`
+- Run: `python -m venv plugins` (or `python3 -m venv plugins` on macOS/Linux)

-- Run the following command to install pybind11. `pip install pybind11==2.13.5`
+- Install pybind11: `pip install pybind11==2.13.5`
+  - Optional: verify pybind11’s CMake location for use with CMake:
+    - `python -m pybind11 --cmakedir` (or `python3 -m pybind11 --cmakedir`)
+    - You can pass this to CMake as: `-Dpybind11_DIR="<output of --cmakedir>"`

README_py.md (4)

64-65: Make example config robust to pybind11 discovery issues

Passing pybind11_DIR from the active venv helps avoid hardcoded paths and missing-package confusion.

Apply:

-cmake -B build
+cmake -S . -B build -Dpybind11_DIR="$(python -m pybind11 --cmakedir)"

-cmake -B build
+cmake -S . -B build -Dpybind11_DIR="$(python -m pybind11 --cmakedir)"
 cmake --build build --config Release

---

83-86: Use the exact cloned folder name to avoid confusion

When cloning, the default directory is EmotiBit_Brainflow_SpO2_Algorithm; using the exact name is clearer and avoids copy/paste mistakes.

Apply:

-- `cd` into the `EmotiBit Brainflow SpO2 Algorithm` folder and checkout the following commit: `7bc9dc3b02f361c37e9e917477abefe9f5468a68`
+- `cd EmotiBit_Brainflow_SpO2_Algorithm` and checkout the following commit: `7bc9dc3b02f361c37e9e917477abefe9f5468a68`

-- Follow the instructions under `pybind/README.md` to finish building the algorithm
+- Follow the instructions under `pybind/README.md` in that repository to finish building the algorithm

Please confirm the commit SHA is the intended one for validation.

🛠️ Refactor suggestion

Fix venv name mismatch and strengthen cross‑platform install notes

• Line 43 says the venv folder will be named “plugins” but the command creates “emotibit_plugins”. This will confuse users.
• Prefer “python -m pip …” to ensure the venv’s pip is used.
• Add a macOS/Linux variant for the venv creation command.

Apply:

- - Run the following command `python -m venv emotibit_plugins`
- -  - This creates a new folder called `plugins` containing the virtual Python environment
+ - Run the following command `python -m venv emotibit_plugins`
+   - On macOS/Linux you may need: `python3 -m venv emotibit_plugins`
+ -  This creates a new folder called `emotibit_plugins` containing the virtual Python environment
@@
-- Run the following command to install pybind11. `pip install pybind11==2.13.5`
+- Run the following command to install pybind11. `python -m pip install pybind11==2.13.5`

Follow-up: please standardize this venv name (“emotibit_plugins”) across CMake and the rest of the repo to avoid breakage when locating pybind11.

I can scan the repo and draft diffs to align the venv name everywhere if helpful.

In README_py.md around lines 39 to 49, the venv creation notes are inconsistent
and not cross-platform: the text incorrectly claims the venv folder will be
named "plugins" while the command creates "emotibit_plugins"; the pip install
should use the venv's pip via "python -m pip"; and there is no macOS/Linux
variant for the venv creation command. Update the paragraph to consistently use
"emotibit_plugins" as the venv name, change the install command to use "python
-m pip install pybind11==2.13.5", add a macOS/Linux venv creation example (e.g.,
python3 -m venv emotibit_plugins), and add a short note to standardize this venv
name across CMake and the repo (or link to a follow-up task to align
references).

In README_py.md around lines 72 to 76, the example uses the incorrect lowercased
directory name "pyExample_emotibitPacket" which will break on case-sensitive
filesystems; update the README to use the correct casing
"pyExample_EmotiBitPacket" wherever that path is referenced (e.g., "cd to
`pyExample_EmotiBitPacket`") and scan the file for any other occurrences of the
incorrect casing and fix them to match the actual directory name.
