What is it?

Notepad4 is a text and code editor for Windows built on the Scintilla editing component. It provides syntax highlighting, code folding, auto-completion and API lists for a wide range of programming languages and document formats, including C/C++, Python, Go, Rust, JavaScript, Markdown and many others.

The project is a modern C++ rewrite of Notepad2 and Notepad2-mod. It adds features such as bookmarks, marking all occurrences of a word or selection, context-based auto-completion, color preview in call tips, and Base64 and number-base conversion. It also supports Direct2D/DirectWrite rendering, font ligatures, color emoji, and improved input for Chinese, Japanese and Korean.

The package bundles matepath, a file browser plugin derived from metapath. Builds are available for x86, x64 and ARM64 Windows, and the editor can run under Wine on other systems.
