Tcl_RecordAndEval(3) Tcl Library Procedures Tcl_RecordAndEval(3)
Tcl_RecordAndEval - save command on history list before evaluating
Tcl_RecordAndEval(interp, cmd, flags)
Tcl_Interp *interp (in) Tcl interpreter in which to evaluate
const char *cmd (in) Command (or sequence of commands) to
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.
