Installation

Pleno ships as five programs: pleno (run, check, format, test), plm (packages), pleno-lsp (language server), pleno-dap (debugger) and pleno-repl.

With VS Code

Install the VS Code extension, then run Pleno: Install or Update Toolchain from the Command Palette. It downloads the latest release for your system, checks its SHA-256 checksum, and makes the tools available in VS Code's terminals.

With the install script

Linux and macOS

curl -fsSL https://raw.githubusercontent.com/otabekoff/pleno/main/scripts/install.sh | sh

Windows

irm https://raw.githubusercontent.com/otabekoff/pleno/main/scripts/install.ps1 | iex

The script downloads the latest release from GitHub into ~/.pleno/bin (Windows: %USERPROFILE%\.pleno\bin) and adds that folder to your PATH. Open a new terminal afterwards.

By hand

1. Download the archive for your platform from the releases page:

   Platform	Archive
   Windows (x64)	pleno-vX.Y.Z-x86_64-pc-windows-msvc.zip
   Linux (x64)	pleno-vX.Y.Z-x86_64-unknown-linux-gnu.tar.gz
   Linux (ARM64)	pleno-vX.Y.Z-aarch64-unknown-linux-gnu.tar.gz
   macOS (Intel)	pleno-vX.Y.Z-x86_64-apple-darwin.tar.gz
   macOS (Apple silicon)	pleno-vX.Y.Z-aarch64-apple-darwin.tar.gz

2. Check it against the .sha256 file next to it.

3. Extract it and put the programs in a folder on your PATH.
