Paradox Modding Toolkit for Notepad++

Plugin 0.2.2 with px-lsp 0.3.8. The bundled server comes from the PX Toolkit 0.5.5 prerelease. Download 0.2.2 for x86, x64 or ARM64 Notepad++.

Language tools for Crusader Kings III, Victoria 3, and Europa Universalis V mods. The plugin connects Notepad++ to px-lsp.

Notepad++ plugin version 0.2.2 adds clearer settings, more Windows architectures, and reliability fixes. It bundles px-lsp 0.3.8 and Windows Node. The plugin, the language server, and the main PX Toolkit have separate version numbers. Available releases.

Limited maintenance

I do not plan to develop this Notepad++ version much further. My main focus is PX Toolkit for VS Code, and I do not use Notepad++ myself. I may fix reported issues when time permits, but regular feature updates and response times are not guaranteed. Community contributions and a new maintainer are welcome. Open an issue to report a problem or discuss taking over maintenance.
