nvda-addon-kit

Scaffold, build, translate and install NVDA add-ons from a single addon.toml.

This is the successor to the SCons-based addonTemplate. Instead of forking a template repository and editing buildVars.py, you install a tool:

pip install nvda-addon-kit
nvaddon init myAddon
cd myAddon
nvaddon build

Commands

Run nvaddon <command> --help for the flags each one accepts.

Releasing

nvaddon release 1.2.0 --channel beta

This writes the version and channel into addon.toml, commits, tags 1.2.0-beta, and pushes the commit and tag with git push --atomic so the remote takes both or neither. If anything fails the working tree is restored to where it started, leaving no half-made release behind. Use --no-push to stop before publishing.

addon.toml

[addon]
name = "myAddon"
# Translators: Summary/title for this add-on, shown on install and in the add-on store.
summary = "Add-on user visible name"
# Translators: Long description shown for this add-on in the add-on store.
description = """Description for the add-on.
It can span multiple lines."""
version = "1.0.0"
author = "Name <name@domain.com>"
minimumNVDAVersion = "2024.1"
lastTestedNVDAVersion = "2025.3"

[build]
pythonSources = ["addon/globalPlugins/**/*.py"]

[l10n]
baseLanguage = "en"

The comment above a translatable key becomes that string's translator note in the generated .pot, exactly as # Translators: comments in buildVars.py did:

#. Translators: Summary/title for this add-on, shown on install and in the add-on store.
#: addon.toml:3
msgid "Add-on user visible name"
msgstr ""

Migrating an existing add-on

cd myExistingAddon
pip install nvda-addon-kit
nvaddon migrate
nvaddon check
nvaddon build

migrate leaves buildVars.py, sconstruct and site_scons/ in place; delete them once you are satisfied the build output matches.
