Concrete Tool Capabilities And Performance-Relevant Mechanics
sqlite-scanner is presented as the proof-of-concept: it identifies SQLite DB files via magic-header byte matching, uses goroutine concurrency to accelerate scanning, and emits results in pipeline-friendly formats (text/JSON/NDJSON) with optional file sizes. The change is less about novel detection and more about demonstrating a compiled, concurrent CLI being distributable and usable in Python-centric workflows.
- sqlite-scanner detects SQLite databases by matching the first 16 bytes of a file against the SQLite magic header "SQLite format 3\x00".
- sqlite-scanner accelerates scanning using concurrent goroutines.
- sqlite-scanner is a Go CLI tool that scans filesystems to find SQLite database files.
- sqlite-scanner can stream results in plain text, JSON, or newline-delimited JSON.
- sqlite-scanner can optionally include file sizes in its output.
Operationalization: Automation And Release Workflow
The corpus describes tooling (go-to-wheel) and a repeatable build/test/publish workflow: build multi-platform wheels with embedded version and metadata, validate via uv, then upload dist artifacts to PyPI using twine authenticated by an API token. The delta is an apparent reduction in ongoing operational friction for distributing many Go CLIs this way.
- go-to-wheel is a tool created to automate building Python wheels from Go projects.
- go-to-wheel is published to PyPI for execution via "uvx go-to-wheel".
- sqlite-scanner wheels for multiple OS/architectures were built using go-to-wheel with parameters including embedding a version variable, metadata, and a README.
- The produced sqlite-scanner wheel was validated by running it directly via uv before uploading.
- Publishing the produced wheel set to PyPI can be done by uploading dist/* with twine and authenticating using a saved PyPI API token.
Binary Distribution Via Pypi/Uvx
The corpus describes a distribution pattern where end users can execute a Go CLI through Python tooling (uvx) without manual downloads or compilation, relying on platform/architecture-tagged wheels for automatic artifact selection. The key change is treating PyPI (via uv/pip) as an OS/arch-aware binary distribution channel, not only a Python-source package index.
- pip and uv select the correct precompiled binary wheel by matching the wheel filename platform and architecture tags to the user's system.
- Publishing Go binaries as platform-specific Python wheels on PyPI can make a Go CLI executable available via a simple uvx invocation.
- sqlite-scanner can be run without manual downloads or compilation using "uvx sqlite-scanner".
- When run via uvx, sqlite-scanner defaults to scanning the current directory unless directories are provided as arguments.
Wheel Wrapper Design For Non-Python Executables
The mechanism for making a bundled executable behave like an installed Python CLI is an entry point that locates the embedded binary, adjusts execute permissions on Unix, and launches it with OS-appropriate process semantics (exec on Unix, subprocess on Windows). This is the core enabling detail that generalizes beyond any specific Go project.
- The sqlite-scanner wheel bundles the compiled binary alongside a Python entry point that locates the binary and ensures it is executable on Unix.
- The sqlite-scanner Python entry point runs the bundled binary using exec on Unix and subprocess on Windows.
Python Ecosystem Composability Via Subprocess-Called Binaries
The corpus claims a strategic benefit beyond end-user installs: Python packages can declare a binary wheel as a dependency and call the embedded executable. datasette-scan is a concrete example that depends on sqlite-scanner to scan directories and attach discovered databases to a Datasette instance.
- datasette-scan is a Datasette plugin that depends on sqlite-scanner and uses it to scan directories for SQLite databases and attach them to a Datasette instance.
- Packaging Go binaries as wheels enables them to be used as dependencies by other Python packages, which can call the binary via subprocess.
Unknowns
- Does uvx-based installation and execution of these binary wheels work reliably across Windows/macOS/Linux and across common CPU architectures in real-world environments?
- What are the practical limitations or failure modes of the wrapper approach (permissions on Unix, subprocess behavior on Windows, path resolution, and error propagation)?
- How large are the resulting wheel artifacts, and does wheel size materially impact distribution or installation speed for typical users and CI systems?
- How stable is PyPI’s stance on hosting and distributing binary-only wheels that primarily package non-Python executables?
- To what extent will third-party maintainers adopt go-to-wheel or similar tooling to distribute additional Go CLIs through PyPI?
