Installation

The l research preview ships as an osx binary. More architectures will follow.

Download

Download the osx artifact from the download page, after accepting the research-preview terms.

Install

Clear Apple’s quarantine attribute, make it executable, and run it:

xattr -cr l_m64 && chmod +x $_ && ./l_m64

To avoid a global install, keep the binary in a project directory and call it by path.

First run

Start the REPL:

l

Run a small expression:

l>sum 1 2 3 4 5 6
21

Updating

Builds are versioned by release folder. Download a newer one and replace the binary.
