What it is

Notepad++ is a free, open-source code editor for Windows that provides syntax highlighting, code folding, and language support for 100+ programming languages via its built-in lexer system. It's a lightweight Notepad replacement with extensibility through plugins (UDL 2.0 and Scintilla-based), making it the go-to text editor for Windows developers who want something faster and more feature-rich than Notepad or VS Code alternatives. Monolithic C++ desktop application: PowerEditor/ contains the main UI and editor engine; PowerEditor/Test/ holds language-specific function parsing tests (ada/, cpp/, bash/, etc. with unitTest files and .expected.result golden files); .github/workflows/ manages…

Start here

Open these first:

• PowerEditor/Test/FunctionList — Core test suite directory containing language-specific function list parsing tests that validate the parser's correctness…
• .github/workflows/CI_build.yml — GitHub Actions workflow that orchestrates the continuous integration pipeline; understanding this reveals how the project…
• BUILD.md — Essential documentation for building Notepad++ from source; required reading before any local development or contribution.
• CONTRIBUTING.md — Official contribution guidelines defining the project's standards, workflow, and expectations for all contributors.
• LICENSE — GPL License governing the entire codebase; critical to understand legal obligations and restrictions when contributing.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/notepad-plus-plus/notepad-plus-plus.git
cd notepad-plus-plus
cat BUILD.md  # Read Windows-specific build instructions (Visual Studio required)

Build requires Visual Studio 2019+ on Windows; no Linux/Mac builds supported. Follow BUILD.md for compiler flags and Scintilla submodule setup.

Daily commands:

This is a compiled Windows desktop app, not a dev server. Build steps: open PowerEditor/visual.cpp/.sln in Visual Studio → compile → run notepad++.exe. No npm/Python scripts visible for local dev. See BUILD.md for detai…

Key cautions & unknowns

• Could not verify license from the available repository evidence
• Windows-only: Codebase uses Win32 API extensively; cross-platform builds will fail. Visual Studio required: GCC/Clang not supported; must use MSVC. Scintilla submodule: Git clone must include…
• License evidence is incomplete or ambiguous.
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
