Verify your installation
Three quick checks confirm that Otter is installed and working.
1. Check the version
PowerShell
otter --version
Output
Otter 1.0.0
Running from the project folder without installing? Use .\otter.cmd --version.
2. Try the interactive session
Run otter with nothing after it to start the REPL, type a statement, and press Enter. Type exit to leave.
PowerShell
otter
3. Run a program
Save one line as hello.ot and run it:
Otter
say "Hello, world!"
PowerShell
otter hello.ot
Output
Hello, world!
If a command is not found, see Troubleshooting: it is almost always a terminal that was opened before the PATH changed.
