Install

On Linux and macOS, run:

curl -fsSL https://raw.githubusercontent.com/poplar-mc/poplar/main/install.sh | sh

On Windows, run this in PowerShell:

irm https://raw.githubusercontent.com/poplar-mc/poplar/main/install.ps1 | iex

The script downloads the latest release for your platform and installs poplar with its standard library. On Linux and macOS it installs to ~/.local, and on Windows to %LOCALAPPDATA%\Programs\poplar. To install somewhere else, set POPLAR_PREFIX.

Update

poplar update checks for a newer release and asks before it installs one. See the CLI page for its options.

Language server

Poplar comes with a language server, which you start with poplar lsp. It reports errors as you type and handles hover, go to definition and completion.

Build from source

Building Poplar yourself needs Zig 0.17.0:

git clone https://github.com/poplar-mc/poplar.git
cd poplar/compiler
zig build -Doptimize=ReleaseSafe -p ~/.local

This installs the compiler to ~/.local/bin/poplar and the standard library to ~/.local/lib/poplar/std/.

The compiler looks for the standard library at ../lib/poplar/std next to its binary. If you move the binary, set POPLAR_STD to the standard library folder.
