Installation

RDBMS Playground is a single self-contained program. There is nothing to configure and no separate database to install — everything it needs is built in.

Pick the tab for your platform — we try to select it automatically — then use whichever method you prefer. The one-line installers are the quickest if you just want to get going.

Linux

One-line installer

curl -fsSL https://git.lazyeval.net/oli/rdbms-playground/raw/branch/main/scripts/install.sh | sh

It detects your CPU, installs to ~/.local/bin, and prints a hint if that directory isn’t on your PATH. Set RDBMS_INSTALL_DIR to install elsewhere, or RDBMS_VERSION=vX.Y.Z to pin a version. Prefer to read a script before running it? It lives at scripts/install.sh.

Homebrew

brew tap lazyeval/tap https://git.lazyeval.net/lazyeval/homebrew-tap
brew install lazyeval/tap/rdbms-playground

macOS

One-line installer

curl -fsSL https://git.lazyeval.net/oli/rdbms-playground/raw/branch/main/scripts/install.sh | sh

It detects your CPU (Apple Silicon or Intel), installs to ~/.local/bin, and prints a hint if that directory isn’t on your PATH. Set RDBMS_INSTALL_DIR to install elsewhere, or RDBMS_VERSION=vX.Y.Z to pin a version. Prefer to read a script before running it? It lives at scripts/install.sh.

Homebrew

brew tap lazyeval/tap https://git.lazyeval.net/lazyeval/homebrew-tap
brew install lazyeval/tap/rdbms-playground

Windows

One-line installer (PowerShell)

irm https://git.lazyeval.net/oli/rdbms-playground/raw/branch/main/scripts/install.ps1 | iex

It downloads the matching .exe, verifies its checksum, installs to %LOCALAPPDATA%\Programs\rdbms-playground, and adds that folder to your user PATH. Use -InstallDir to choose a different location or -Version to pin a release.

Scoop

scoop bucket add lazyeval https://git.lazyeval.net/lazyeval/scoop-bucket
scoop install rdbms-playground

winget

A winget package (winget install LazyEvaluation.RdbmsPlayground) is on its way and awaiting review in the public winget catalogue. Until it lands, use Scoop or the PowerShell one-liner above.

With cargo

These work on any platform with a Rust toolchain. Install from crates.io:

cargo install rdbms-playground

For a faster install that fetches a prebuilt binary instead of compiling, use cargo-binstall (install it first — it is not part of cargo itself):

cargo binstall rdbms-playground

Prebuilt binaries

Every release publishes static Linux, standalone Windows, and macOS binaries (x86_64 and aarch64), each with a .sha256 checksum, on the releases page. Download the one for your platform, make it executable if needed, and put it somewhere on your PATH.

Run it

Start the playground with no arguments and it opens a fresh, automatically named temporary project so you can start experimenting immediately:

rdbms-playground

To open an existing project, pass its path:

rdbms-playground path/to/project

Useful options (run rdbms-playground --help for the full list):

Option	What it does
--resume	Reopen the most recently used project.
--data-dir <PATH>	Use a different location for stored projects.
--theme <light|dark>	Force a theme instead of auto-detecting.
--mode <simple|advanced>	Start in a specific input mode.
--version	Print the version and exit.

The full list, with examples, is on the command-line options page.

Next: create your first project.
