Tcl_RecordAndEval()

save command on history list before evaluating 

Tcl Library Procedures


SYNOPSIS

#include <tcl.h>

int Tcl_RecordAndEval(interp, cmd, flags)


ARGUMENTS

Tcl_Interp *interp (in) 

Tcl interpreter in which to evaluate command.

char *cmd (in) 

Command (or sequence of commands) to execute.

int flags (in) 

An OR'ed combination of flag bits. 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.


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 don't 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-invoked 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 object-based procedure Tcl_RecordAndEvalObj(). That object-based procedure records and optionally executes a command held in a Tcl object instead of a string.
