TCL_NO_EVAL means record the +command but don't evaluate it. TCL_EVAL_GLOBAL means evaluate +the command at global level instead of the current stack level. +.BE + +.SH DESCRIPTION +.PP +\fBTcl_RecordAndEval\fR is invoked to record a command as an event +on the history list and then execute it using \fBTcl_Eval\fR +(or \fBTcl_GlobalEval\fR if the TCL_EVAL_GLOBAL bit is set in \fIflags\fR). +It returns a completion code such as TCL_OK just like \fBTcl_Eval\fR +and it leaves information in \fIinterp->result\fR. +If you don't want the command recorded on the history list then +you should invoke \fBTcl_Eval\fR instead of \fBTcl_RecordAndEval\fR. +Normally \fBTcl_RecordAndEval\fR 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-invoked commands. +If the \fIflags\fR argument contains the TCL_NO_EVAL bit then +the command is recorded without being evaluated. +.PP +Note that \fBTcl_RecordAndEval\fR has been largely replaced by the +object-based procedure \fBTcl_RecordAndEvalObj\fR. +That object-based procedure records and optionally executes +a command held in a Tcl object instead of a string. + +.SH "SEE ALSO" +Tcl_RecordAndEvalObj + +.SH KEYWORDS +command, event, execute, history, interpreter, record |
