Real-World Usage of the CLI

In this page, you can find real-life examples on the CLI's usage.

Evaluating from a file

Assuming we have a file called myfile.rsea, it's easy to evaluate it without any coding skills.

# !standard: official-25
# myfile.rsea
win.+ -> "You're on Windows"
(ubuntu|debian).* -> "Debian-based Linux"
.+ -> "Sorry, I don't know your OS"

>>> cat myfile.rsea | RSML.CLI eval --expand-any
Debian-based Linux
