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.
