Contributions Guide

Hi! We’re glad that you’re interested in contributing to idf-build-apps. This document would guide you through the process of setting up the development environment, running tests, and building documentation.

Supported ESP-IDF Versions

Here’s a table shows the supported ESP-IDF versions and the corresponding Python versions.

ESP-IDF Version	ESP-IDF Supported Python Versions	idf-build-apps Releases
4.1	2.7, 3.4+	1.x
4.2	2.7, 3.4+	1.x
4.3	2.7, 3.4+	1.x
4.4	2.7, 3.4+	1.x
5.0	3.7+	main (2.x)
5.1	3.7+	main (2.x)
5.2	3.7+	main (2.x)
5.3	3.8+	main (2.x)
master (5.4)	3.8+	main (2.x)

idf-build-apps is following the semantic versioning. The major version of idf-build-apps is the same as the ESP-IDF version it supports. For example, idf-build-apps 1.x supports ESP-IDF 4.x, and idf-build-apps 2.x supports ESP-IDF 5.x.

In order to compatible to all 5.x ESP-IDF versions, please don’t forget to keep the code compatible with python 3.7, even it’s end of life on 2023-06-05.

Setup the Dev Environment

Create virtual environment
```
python -m venv venv
```
Activate the virtual environment
```
. ./venv/bin/activate
```
Install flit

We use flit to build the package and install the dependencies.
```
pip install flit
```
Install all dependencies

All dependencies would be installed, and our package idf-build-apps would be installed with editable mode.
```
flit install -s
```

Run Testing

We use pytest for testing.

pytest

Build Documentation

We use sphinx and autodoc for generating documentation and API references. Besides, we treat warnings as errors while building the documentation. Please fix them before your commits got merged.

cd docs && make html

For documentation preview, you may use any browser you prefer. The executable has to be searchable in PATH. For example we’re using firefox here.

firefox _build/html/index.html
