Integration with custom applications (extensions, plugins)

We recommend using PlatformIO Core Installer Script when you integrate PlatformIO Core into an application, such as an extension or plugin for IDE.

Prerequisite

Python Interpreter

PlatformIO Core Installer Script is written in Python and is compatible with Python 2.7+ and Python 3.5+. We highly recommend using the latest Python 3.

Python is installed by default on the most popular Unix OS (macOS, Linux, FreeBSD). If there is no Python on a user machine (you can check running python --version), we have 2 options:

  1. Ask the user to install Python 3 using our guide Install Python Interpreter

  2. You can automatically Download Portable Python 3 (API) and unpack it in a cache folder of your application. Later, you can use unpacked_protable_python_dir/python.exe for the installer script.

Installer Script

There are 2 options on how to work with PlatformIO Core Installer Script:

  1. Bundle get-platformio.py file into your application

  2. Download get-platformio.py file on demand.

In both cases, you will need to have get-platformio.py script on the end-user machine. You can copy or download it to a cache/temporary folder.

A list of arguments and options for the installer script is available via

python get-platformio.py --help

Workflow

We will describe a simple workflow on how to automatically install PlatformIO Core (CLI) for end-user of your application/extension. We assume that get-platformio.py script is already copied/downloaded and exists on the end-user machine. See above for how to get it.

Step 1. Where is PlatformIO Core installed?

You should check the PlatformIO Core installation state each time when the user starts your application. You need to call the Installer Script with check core arguments:

python get-platformio.py check core

This command returns 0 “exit code” when PlatformIO Core is already installed and is ready for use, otherwise, the non-zero code of the subprocess will be returned and you need to install PlatformIO Core (see Step #2 below).

If you need to have full information about the PlatformIO Core installation state, please run with --dump-state option and specify a folder or a full path where to save data in JSON format:

get-platformio.py check core --dump-state tmpdir/pioinstaller-state.json

Now, read JSON file and use platformio_exe binary to call PlatforIO Core using CLI (see CLI Guide). You can also export penv_bin_dir into the system environment PATH variable and the platformio command will be available without a full path.

Example of pioinstaller-state.json run on macOS:

{
  "cache_dir": "/Users/Freedom/.platformio/.cache",
  "core_dir": "/Users/Freedom/.platformio",
  "core_version": "4.3.1",
  "installer_version": "0.2.0",
  "is_develop_core": false,
  "penv_bin_dir": "/Users/Freedom/.platformio/penv/bin",
  "penv_dir": "/Users/Freedom/.platformio/penv",
  "platformio_exe": "/Users/Freedom/.platformio/penv/bin/platformio",
  "python_exe": "/Users/Freedom/.platformio/penv/bin/python",
  "system": "darwin_x86_64"
}

Step 2. Install PlatformIO Core

To install PlatformIO Core into the virtual environment in an automatic mode, please call the installer script without any arguments:

python get-platformio.py

Available options:

  • --verbose, verbose output

  • --dev, install the latest development version of PlatformIO Core

  • --ignore-python, a path to Python to be ignored (multiple options and Unix wildcards are allowed)

More options are available at python get-platformio.py --help.

Installer Script will return exit code 0 on success, otherwise non-zero code and error explanation.

Next time just use again python get-platformio.py check core as described in Step #1 (see above).
