Bindings

PRQL has bindings for many languages, in three tiers:

• Supported
• Unsupported
• Nascent

Supported

Supported bindings require:

• A maintainer.
• Implementations of the core compile functions.
• Test coverage for these functions.
• A published package to the language's standard package repository.
• A script in Taskfile.yaml to bootstrap a development environment.
• Any dev tools, such as a linter & formatter, in pre-commit or MegaLinter.

The currently supported bindings are:

• JavaScript
• Python
• R
• Rust

Most of these are in the main PRQL repo, and we gate any changes to the compiler's API on compatible changes to the bindings.

Unsupported

Unsupported bindings work, but don't fulfil all of the above criteria. We don't gate changes to the compiler's API. If they stop working, we'll demote them to nascent.

• Java
• Elixir
• prqlc-c, the C bindings

Nascent

Nascent bindings are in development, and may not yet fully work.

• .NET
• PHP

Naming

Over time, we're trying to move to a consistent naming scheme:

• Crates are named prqlc-$lang.
• Where possible, packages are published to each language's package repository as prqlc.
