rgpdf

繁體中文 · English

rgpdf is a cross-platform desktop application for searching text-layer PDFs with plain text or regular expressions. Matches appear as they are found and can be opened in an asynchronous page preview with precise, configurable highlighting.

Features

• Search multiple PDFs in a folder, optionally including subfolders.
• Plain-text and regular-expression modes with optional case sensitivity.
• Matches across lines and page boundaries, including line-end dehyphenation.
• Incremental per-match results without blocking the interface.
• Three coordinated views for files, matching passages, and PDF page preview.
• Per-character highlight geometry and configurable highlight colors.
• English and Traditional Chinese interfaces, plus system/light/dark themes.
• Persistent search and appearance preferences.

rgpdf searches existing PDF text layers. It does not perform OCR or modify source files.

Install the latest release

Windows standalone download

Download the versioned rgpdf-*-windows-x86_64.exe and its .sha256 file from the latest GitHub Release. The executable is currently unsigned, so Windows SmartScreen may show an unknown-publisher warning. Verify that the SHA-256 value matches the published file before choosing to run it.

No Python or uv installation is required for the standalone executable.

Install with uv

Install uv, then install the latest release from PyPI:

uv tool install rgpdf

Run the application:

rgpdf

To update an existing installation:

uv tool upgrade rgpdf

Windows and macOS are supported; uv manages the required Python environment.

To install the latest source release directly from GitHub instead, use the moving latest tag:

uv tool install "git+https://github.com/codemee/rgpdf.git@latest"

Development

git clone https://github.com/codemee/rgpdf.git
cd rgpdf
uv sync
uv run pytest
uv run rgpdf

Build a self-contained Windows executable (Python and uv are only required on the build machine):

uv sync --frozen
./scripts/build-windows.ps1 -Python .venv/Scripts/python.exe

The result is dist/rgpdf.exe. GitHub Actions also publishes the executable, LICENSE, and third-party notices as the rgpdf-windows-x86_64 workflow artifact. Public release distribution additionally requires the corresponding source materials listed in the release compliance checklist.

See Technical details for architecture, matching semantics, concurrency, and release engineering. Version history is in the changelog.

Releases

Immutable releases use version tags such as v0.0.3. The movable latest Git tag always points to the newest published source release. PyPI provides the canonical packaged release.
