GAD language
GAD is a programming language written in Haitian Creole, invented by GETHO GUERRIER / GRAN LAKU COMPANY. Its compiler comes with WASDEV: write, run, check and build GAD programs without installing anything.
What GAD is
GAD keywords are Creole words: montre prints a value, si means if, fè defines an action and fini closes a block. The language does not change for other countries: a developer who does not read Creole uses the dictionary and the translate command.

- The compiler in WASDEV is GAD 1.4.0.
- Accents are optional in keywords:
fèandfeare the same word. - One compiler runs the program, checks it, formats it, tests it and builds it.
What you can build today
Every line of this table was run for these pages. The sub-pages show the code, the command and what the terminal printed.
| Kind of program | How |
|---|---|
| Terminal program | gad kouri |
| Windows application (.exe) | gad bati |
| Desktop window | sèvi ak vizyon |
| Static web page | gad bati … pou web |
| HTTP server and API | sèvi ak simbi |
| Data that stays on disk | sèvi ak depo, sql |
| Tests | gad tès |
| Program for a device | <aparèy> |
- GAD Mobile (Android / iOS) and GAD RASIN (firmware flashed on a board) are not in the compiler yet. WASDEV shows them in the Run panel as not available.

gad-examples.zip. - Extract the ZIP in a folder of your choice.
- In WASDEV, open the File menu, choose Open Folder… and select the folder
gad-examples. - Open a file, for example

Your first GAD program
Create a GAD file in WASDEV, run it, check it and format it. Every command on this page was run in the WASDEV terminal.
2The GAD language
The words of the language: values, conditions, loops, actions, lists and models, each with a short example.
3Library and modules
What GAD gives without asking, what it gives only when the program asks with sèvi ak, and the library families.
Desktop applications
A window drawn by GAD on the graphics card, a state that updates the screen, and a Windows application you can double-click.
5Web pages and servers
The same interface code becomes a static web page, and a few lines make an HTTP server with a database.
6Tests, projects and packages
Write tests in GAD, declare a project with lakou.gad, start every GAD target from the Run panel and add packages.
7Devices and firmware
What GAD does today for a program that runs on a machine, what is proved by the compiler, and what is not available yet.
