10 '\" The definitions below are for supplemental macros used in Tcl/Tk
13 '\" .AP type name in/out ?indent?
14 '\" Start paragraph describing an argument to a library procedure.
15 '\" type is type of argument (int, etc.), in/out is either "in", "out",
16 '\" or "in/out" to describe whether procedure reads or modifies arg,
17 '\" and indent is equivalent to second arg of .IP (shouldn't ever be
18 '\" needed; use .AS below instead)
21 '\" Give maximum sizes of arguments for setting tab stops. Type and
22 '\" name are examples of largest possible arguments that will be passed
23 '\" to .AP later. If args are omitted, default tab stops are used.
26 '\" Start box enclosure. From here until next .BE, everything will be
27 '\" enclosed in one large box.
30 '\" End of box enclosure.
33 '\" Begin code excerpt.
38 '\" .VS ?version? ?br?
39 '\" Begin vertical sidebar, for use in marking newly-changed parts
40 '\" of man pages. The first argument is ignored and used for recording
41 '\" the version when the .VS was added, so that the sidebars can be
42 '\" found and removed when they reach a certain age. If another argument
43 '\" is present, then a line break is forced before starting the sidebar.
46 '\" End of vertical sidebar.
49 '\" Begin an indented unfilled display.
52 '\" End of indented unfilled display.
55 '\" Start of list of standard options for a Tk widget. The
56 '\" options follow on successive lines, in four columns separated
60 '\" End of list of standard options for a Tk widget.
62 '\" .OP cmdName dbName dbClass
63 '\" Start of description of a specific option. cmdName gives the
64 '\" option's name as specified in the class command, dbName gives
65 '\" the option's name in the option database, and dbClass gives
66 '\" the option's class in the option database.
69 '\" Print arg1 underlined, then print arg2 normally.

246 .TH Tcl_RecordAndEval 3 7.4 Tcl "Tcl Library Procedures"
249 Tcl_RecordAndEval \- save command on history list before evaluating
252 \fB#include <tcl.h>\fR
255 \fBTcl_RecordAndEval\fR(\fIinterp, cmd, flags\fR)
257 .AS Tcl_Interp *interp;
258 .AP Tcl_Interp *interp in
259 Tcl interpreter in which to evaluate command.
261 Command (or sequence of commands) to execute.
263 An OR'ed combination of flag bits. TCL_NO_EVAL means record the
264 command but don't evaluate it. TCL_EVAL_GLOBAL means evaluate
265 the command at global level instead of the current stack level.
270 \fBTcl_RecordAndEval\fR is invoked to record a command as an event
271 on the history list and then execute it using \fBTcl_Eval\fR
272 (or \fBTcl_GlobalEval\fR if the TCL_EVAL_GLOBAL bit is set in \fIflags\fR).
273 It returns a completion code such as TCL_OK just like \fBTcl_Eval\fR
274 and it leaves information in the interpreter's result.
275 If you don't want the command recorded on the history list then
276 you should invoke \fBTcl_Eval\fR instead of \fBTcl_RecordAndEval\fR.
277 Normally \fBTcl_RecordAndEval\fR is only called with top-level
278 commands typed by the user, since the purpose of history is to
279 allow the user to re-issue recently-invoked commands.
280 If the \fIflags\fR argument contains the TCL_NO_EVAL bit then
281 the command is recorded without being evaluated.
283 Note that \fBTcl_RecordAndEval\fR has been largely replaced by the
284 object-based procedure \fBTcl_RecordAndEvalObj\fR.
285 That object-based procedure records and optionally executes
286 a command held in a Tcl object instead of a string.
