Command line: giving a tool a written instruction
A command-line interface, or CLI, lets you control a tool by typing a command. A terminal is a window that shows this text conversation. A shell, such as PowerShell, reads your command and starts the requested tool.
These terms describe different pieces. Pliro’s CLI is the tool you call; PowerShell is not the Pliro language.
Two kinds of commands
In a terminal with Pliro installed and available, you can use:
pliro version
To check a source file in the current folder:
pliro check hello.pliro
The second command assumes hello.pliro exists. Use the actual filename of your program. These are shell commands, so do not paste them into a .pliro source file.
Inside a Pliro source file, an instruction might instead be say "Hello". A REPL lets you try language instructions interactively; the REPL guide explains its own controls.
Read before pressing Enter
The working directory is the folder a command currently starts from when resolving relative paths. Check that folder when a tool says it cannot find a file.
Only run commands you understand. Shell commands can have effects outside your Pliro project. Start with harmless commands such as showing the version or checking your own source.
