REPL

A real terminal running the actual @enumeratio/cli eval core in your browser — not a recording. Pick an example from the dropdown, or type your own. Results are exact; :help lists every command.

• Input: Epsil by default (Binomial(10, 3), 1/2 + 1/3, Sqrt(144)); wrap LaTeX in $…$; :latex / :wolfram / :mathjson / :epsil force a syntax for one line.
• Output: :form <name> switches how results print (:forms to list).
• Graphics: :plot <expr> and :glyph <kind> <list> draw below the terminal.
• Environments: :env print / :env pipe reduce every result for somewhere that cannot drive a control — a slider pins or samples into small multiples; :env auto hands it back. At a real terminal the controls are live instead: see Environments.
• History: Out(n) is the n-th result (%n for short, %/%% for the last two), In(n) re-evaluates the n-th input, InString(n) is the line as typed.
• Keys: ↑/↓ history, ←/→ edit, Ctrl+C cancels a line, Ctrl+L clears.

See the CLI reference for the full command list and the command-line playground for scriptable notatio invocations.
