01. Install and Setup

Prerequisites

• An AI key (such as OpenAI)

Install Raku

The Slangify focus is writing DSLs in Raku. Raku is an open source programming language with built-in Grammar capability. Why Raku?.

Use rakubrew to install a Raku compiler...

...for macOS:

curl https://rakubrew.org/install-on-macos.sh | sh

...for linux:

curl https://rakubrew.org/install-on-perl.sh | sh

See https://raku.org/install for more options.

Raku comes complete with the zef package manager.

Clone the Module

git clone https://github.com/librasteve/Slangify-Tutorial
cd Slangify-Tutorial
zef install --/test .

This will bring in all the dependencies - such as the LLM::Functions module.

Set your API key

LLM::Functions picks up your key from the environment:

export OPENAI_API_KEY=sk-...

See https://raku.land/zef:antononcube/LLM::Functions for other supported LLMs.

You can append the export cmd to your ~/.zshrc or ~/.bashrc.

Verify the install

You should see a JSON string with name, party, time, restaurant, and date fields.
