Article contents:[[tags: manual]] [[toc:]] == Module (chicken repl) This module provides procedures you can use to create your own Read-Eval-Print Loop (REPL). === repl <procedure>(repl [EVALUATOR])</procedure> Start a new read-eval-print loop. Sets the {{reset-handler}} so that any invocation of {{reset}} restarts the read-eval-print loop. Also changes the current exception-handler to display a message, write any arguments to the value of {{(current-error-port)}} and reset. If {{EVALUATOR}} is given, it should be a procedure of one argument that is used in place of {{eval}} to evaluate each entered expression. You can use {{quit}} to terminate the current read-eval-print loop. Encountering end-of-file also terminates the current REPL. === repl-prompt <parameter>(repl-prompt)</parameter> A procedure that should evaluate to a string that will be printed before reading interactive input from the user in a read-eval-print loop. Defaults to {{(lambda () "#;N> ")}}. === quit <procedure>(quit [RESULT])</procedure> In the interpreter {{quit}} exits the currently active read-eval-print loop. In compiled code, it is equivalent to calling {{exit}}. See also the {{repl}} procedure. === reset <procedure>(reset)</procedure> Reset program (Invokes {{reset-handler}}). === reset-handler <parameter>(reset-handler)</parameter> A procedure of zero arguments that is called via {{reset}}. The default behavior in compiled code is to invoke the value of {{(exit-handler)}}. The default behavior in the interpreter is to abort the current computation and to restart the read-eval-print loop. --- Previous: [[Module (chicken read-syntax)]] Next: [[Module (chicken sort)]] Description of your changes:
