Tcl_RecordAndEval - save command on history list before evaluating
#include <tcl.h> int Tcl_RecordAndEval(interp, cmd, flags)
- Tcl_Interp *interp (in)
- Tcl interpreter in which to evaluate command.
- const 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 do not evaluate it. TCL_EVAL_GLOBAL means evaluate the
command at global level instead of the current stack level.
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-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 value-based procedure Tcl_RecordAndEvalObj. That value-based procedure records and optionally executes a command held in a Tcl value instead of a string.
