Tcl_RecordAndEval(3) Tcl Library Procedures Tcl_RecordAndEval(3) ________________________________________________________________________________ NAME Tcl_RecordAndEval - save command on history list before evaluating SYNOPSIS #include <tcl.h> int Tcl_RecordAndEval(interp, cmd, flags) ARGUMENTS Tcl_Interp *interp (in) Tcl interpreter in which to evaluate com- mand. const char *cmd (in) Command (or sequence of commands) to exe- cute. int flags (in) An OR'ed combination of flag bits. TCL_NO_EVAL means record the command but do not evaluate it. TCL_EVAL_GLOBAL means evaluate the command at global level in- stead of the current stack level. ________________________________________________________________________________ DESCRIPTION Tcl_RecordAndEval is invoked to record a command as an event on the history list and then execute it using Tcl_Eval (or Tcl_GlobalEval if the TCL_EVAL_GLOBAL bit is set in flags). It returns a completion code such as TCL_OK just like Tcl_Eval and it leaves information in the interpreter's result. If you do not want the command recorded on the history list then you should invoke Tcl_Eval instead of Tcl_RecordAndEval. Normally Tcl_RecordAndEval is only called with top-level commands typed by the user, since the purpose of history is to allow the user to re-issue recently-in- voked commands. If the flags argument contains the TCL_NO_EVAL bit then the command is recorded without being evaluated. Note that Tcl_RecordAndEval has been largely replaced by the value-based procedure Tcl_RecordAndEvalObj. That value-based procedure records and op- tionally executes a command held in a Tcl value instead of a string.
