Repl and playground
You might want to explore Derw in an interactive fashion, and for that there's two tools that are handy: the repl, and the playground.
Repl
To access the repl, simply run derw repl
.
In the repl, you can enter definitions for imports, types, functions and consts. They will not be evaluated until you use :run
or :show
. Between each definition, you should enter a blank newline so that it will be parsed. If parsed successfully, the repl will inform you - and if not, it will show you any errors.
:run
run will evaluate functions and constants
:show
show will first evaluate the current repl body, then print the value of the named value provided
:eval
eval can be used to run some Derw code without needing a definition
:help
And if you forget all the above, you can use help to get a reminder
Playground
