Hello World

To use FTD language we have to use FPM the package manager and server for FTD.

In this exercise we will install FPM, and run a hello world program.

This installs fpm in /usr/local/bin/fpm. If you are curious this is the source code of fpm-install.sh.

Alternately, you can go to the FPM Releases Page and download the fpm binary for your platform from the latest release as well.

We support recent versions of Linux, Mac and Windows.

To test if the installation worked, run:

And it will show you the fpm help text. Shout out to let everyone know when you are done with this step.

If you get an error message in chat or speak up.

Note: If you have not yet cloned ftd-lang/ftd-workshop repo as mentioned in workshop basics, please do it now: git clone https://github.com/ftd-lang/ftd-workshop.git.

FTD files are organized in FPM as a “fpm package”. This is like npm package for JavaScript or cargo crate for Rust.

A FPM package is a folder containing a file named FPM.ftd and some FTD files.

If you run fpm serve right now and go to http://127.0.0.1:8000 it will fail with message in terminal saying FPM.ftd file is missing.

Lets fix this by creating a FPM.ftd file with the following content:

We have “imported” fpm, a special ftd module (each ftd file is called a fpm module, the way we call .py files python modules).

We have created an instance of fpm.package and passed hello as the name of the package.

Now if you run fpm serve it will pick up FPM.ftd and when you go to the server address (http://127.0.0.1:8000 by default), you will see an empty page.

Congrats, you have created your first FPM package!
