Notepad++ for Linux

A native Linux build of the Notepad++ editor on Qt and Scintilla — same menus, shortcuts and file formats, and it runs real Notepad++ plugin DLLs through Wine.

Description

Notepad++ for Linux

A native Linux build of Notepad++, written in Python with Qt 6 and Scintilla, the same editing component the Windows original is built on. The goal was fidelity, not inspiration. The menu tree, command identifiers, default shortcuts and language definitions are generated from the Notepad++ sources, so the layout matches item for item and your muscle memory carries over.

What it does

• Editing: multi-caret and column selection, the Column Editor, code folding, brace and tag matching, smart highlighting, bookmarks, hidden lines, a change-history margin, all 14 Sort Lines variants, line and case operations, macros, and completion and parameter hints from Notepad++'s own API files.
• Searching: Find, Replace, Find in Files, Find in Projects and Mark, with normal, extended and regex modes, plus a results panel and incremental search.
• Files: encoding detection with the full Encoding menu, EOL conversion, atomic saves, tail -f monitoring, printing, and sessions.
• Unsaved work survives a restart. It uses session snapshots with periodic backup. The session is protected against the editor's own failures by a safety copy and a crash guard that logs internal errors instead of dying.
• Layout: two views with Clone and Move, Document Map, Function List, Document List, Folder as Workspace and Project panels, a Ctrl+Tab switcher, a Document Peeker and the system tray.
• 96 languages, plus Notepad++ User Defined Language files used unchanged. About 400 of them exist in the official collection.
• 94 interface languages from Notepad++'s own translation files, switchable live.
• Light and dark themes, dark mode in seven tones, a Style Configurator, and a Shortcut Mapper covering 324 commands plus Scintilla's own keys.

Real Notepad++ plugins, on Linux

Plugins are Windows DLLs. Instead of inventing a new plugin API, the editor runs the real ones, unmodified, in a small host process under Wine and forwards their Scintilla and Notepad++ messages to the Linux editor. Plugins Admin installs from the official plugin list with SHA-256 verification. MIME Tools, Converter, NppExport, JSTool, XML Tools and ComparePlus were checked working. Without Wine the feature switches itself off and says why.

Install

• AppImage (62 MB): self-contained, runs on any distribution with glibc 2.34 or newer.
• .deb (1.7 MB): for Debian 12+, Ubuntu 24.04+ and Linux Mint 22+; Qt comes from the distribution.
• From source: ./install.sh && ./notepad-plus-plus

How it was built

It was written entirely by Claude (Claude Code) from a short brief, then refined through about two dozen plain-language requests and bug reports from one person testing it on their desktop. There are 403 automated tests. They include runs of the real program from start-up to shutdown, a sweep of every menu command, and checks that every bundled Notepad++ data file parses.

Its own source code is MIT licensed. The data files taken from Notepad++ stay under the GPL v3, as do PyQt and QScintilla. This is an independent reimplementation, not affiliated with the Notepad++ project.

Downloads
