Installation

💡 Installing the pls executable currently requires the Deno CLI version 1.29.2 or higher to be installed. This requirement will be removed once the preview period is over.

To install the Platformscript interpreter on your system, run the following:

$ deno install -A https://platformscript-anztkndh0nng.deno.dev/pls

This will install the pls executable on your path, which you can confirm by running

$ pls --version

Once you have pls installed, you can use it to run PlatformScript programs.

To try it out, create a file called hello-world.yaml and paste the following text into it:

Hello world!

You can now use pls to execute PlatformScript programs. To do this we use the run command. Try it out in your console with the file you just created.

$ pls run hello-world.yaml
Hello world!

💡By default, the result of evaluating a PlatformScript value is itself. Hence the hello world program in PlatformScript is the YAML string Hello world!

What's happening here is that the pls run command is evaluating the PlatformScript module contained in the file hello-world.yaml. But modules can be located anywhere adressable by a URL, not just on the local filesystem. For example, you can run run the preceding example online with the command:

$ pls run https://pls.pub/examples/hello-world.yaml
Hello world!
