Customization

The various phases of the read-eval-print loop may be customized by assigning values to switches.

Settable


\begin{inset}{} Accesses the {\tt READ} part of the read-eval-print loop. Initially, this is {\tt READ}. \end{inset}

Settable


\begin{inset}{} Accesses the {\tt EVAL} part of the read-eval-print loop. Initially, this is {\tt EVAL}. \end{inset}

Settable


\begin{inset}{} Accesses the {\tt PRINT} part of the read-eval-print loop. Initially, this is {\tt PRINT}. \end{inset}

Settable


\begin{inset}{} Accesses the prompting routine used in the read-eval-print loop.... ...s {\tt > } at the top level, {\tt >> } at the level below that, etc. \end{inset}

Settable


\begin{inset}{} If {\tt (LOAD-NOISILY?)} is true (which it is initially), then {... ...tandard compiler only). The output goes to the terminal output port. \end{inset}

Operation


\begin{inset}{} Read-eval-print loops will not print any object which answers tr... ...ote that this is unrelated to the functioning of {\tt PRINT} itself. \end{inset}


\begin{inset}{} Its value is an object which answers true to the {\tt REPL-WONT-... ...INT $\equiv$\ (OBJECT NIL ((REPL-WONT-PRINT? SELF) T)) \end{codexenv}\end{inset}
