Make commands

As a convenience, python-template-cppjswasm uses a Makefile for commonly used commands. You can print the main available commands by running make with no arguments

> make

build                          build the library
clean                          clean the repository
fix                            run autofixers
install                        install library
lint                           run lints
test                           run the tests

Prerequisites

python-template-cppjswasm has a few system-level dependencies which you can install from your machine package manager. Other package managers like conda, nix, etc, should also work fine.

Clone

Clone the repo with:

git clone https://github.com/python-project-templates/python-template-cppjswasm.git
cd python-template-cppjswasm

Install C++ Compiler

Ensure you have a C++ compiler available (e.g. g++, clang++, or MSVC on Windows).

Install Emscripten

Follow the instructions for installing Emscripten SDK for your system. This is required for building the JavaScript/WebAssembly bindings.

Install Python dependencies

Python build and develop dependencies are specified in the pyproject.toml, but you can manually install them:

make requirements

Note that these dependencies would otherwise be installed normally as part of PEP517 / PEP518.

Build

Build the python project in the usual manner:

make build
