MetaCall Polyglot Runtime

MetaCall is a polyglot runtime that lets you call functions across multiple languages as if they were native. This README covers the one-line installer scripts and how to customize your installation.

Quick Links:

• Official Docs
• Releases (Linux)
• Releases (macOS)
• Releases (Windows)

• curl or wget (for Linux/macOS)
• PowerShell v5+ (for Windows)
• Internet access (unless installing from a local tarball)

One-line installer:

• Linux / macOS (bash/zsh):

  curl

  curl -sL https://raw.githubusercontent.com/metacall/install/master/install.sh | sh

  wget

  wget -O - https://raw.githubusercontent.com/metacall/install/master/install.sh | sh

• Windows (PowerShell):

  powershell -NoProfile -ExecutionPolicy Unrestricted -Command \
    "[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12; \
    &([scriptblock]::Create((Invoke-WebRequest -UseBasicParsing 'https://raw.githubusercontent.com/metacall/install/master/install.ps1')))"

By default, these scripts fetch the latest release.

• Install with wget using Docker installer:

[1]: The list of versions are available here.

Example:

• Install tarball version v0.1.0 into D:\MetaCall:

  powershell -NoProfile -ExecutionPolicy unrestricted -Command "[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12; &([scriptblock]::Create((Invoke-WebRequest -UseBasicParsing 'https://raw.githubusercontent.com/metacall/install/master/install.ps1'))) -InstallDir 'D:\MetaCall' -Version '0.1.0'"

Requires docker to be installed.

git clone https://github.com/metacall/install.git metacall-install
cd metacall-install
./test.sh

Windows does not include a test script yet, but you can use install.ps1 script for testing yourself on your computer.

git clone https://github.com/metacall/install.git metacall-install
cd metacall-install
powershell -NoProfile -ExecutionPolicy unrestricted ./install.ps1

Sometimes the domain raw.githubusercontent.com maybe blocked by your ISP. Due to this, you may not be able to install metacall directly from previous commands. In that case, you may clone this repo and directly run install.sh for Linux and run install.ps1 for Windows.
