Notepad++ Plugin Manager
Notepad++ Plugin Manager
The nppPluginManager repository contains the legacy Plugin Manager for Notepad++, a tool that once allowed users to easily install, update, and remove plugins within the editor. It relied on a centrally hosted XML file that listed available plugins, which the manager compared against those already installed. Since 2019, however, the plugin is no longer actively maintained, and the supporting web service that provided plugin lists has been discontinued. Users are now encouraged to rely on Notepad++’s built-in plugin solution instead of this deprecated tool. This project is the old location for the plugin list for Notepad++ Plugin Manager. Please use https://github.com/bruderstein/npppluginmanager for any issues and current code -

This project includes special build scripts that clone Microsoft’s vscode repo, run the build commands, and upload the resulting binaries for you to GitHub releases. These binaries are licensed under the MIT license. Telemetry is disabled. If you want to build from source yourself, head over to Microsoft’s vscode repo and follow their instructions. VSCodium exists to make it easier to get the latest version of MIT-licensed VSCode. Please note that some Visual Studio Code extensions have licenses that restrict their use to the official Visual Studio Code builds and therefore do not work with VSCodium. -

Notepads
A modern, lightweight text editor with a minimalist design
I have been waiting long enough for a modern Windows 10 notepad app to come before I decided to create one myself. Don’t get me wrong, Notepad++, VS Code, and Sublime are great text editors. I have used them all and I will continue to use them in the future. However, they are either too heavy or look less appealing. There are times that I just wanted to use Windows Notepad for things like writing notes or editing config files. So I decided to create a win32 notepad replacement here and try to give it a modern look and feel. Most importantly, it has to be blazingly fast and appeal to everyone. -
