7 .TH Tcl_RecordAndEvalObj 3 8.0 Tcl "Tcl Library Procedures"
8 .\" The -*- nroff -*- definitions below are for supplemental macros used
9 .\" in Tcl/Tk manual entries.
11 .\" .AP type name in/out ?indent?
12 .\" Start paragraph describing an argument to a library procedure.
13 .\" type is type of argument (int, etc.), in/out is either "in", "out",
14 .\" or "in/out" to describe whether procedure reads or modifies arg,
15 .\" and indent is equivalent to second arg of .IP (shouldn't ever be
16 .\" needed; use .AS below instead)
19 .\" Give maximum sizes of arguments for setting tab stops. Type and
20 .\" name are examples of largest possible arguments that will be passed
21 .\" to .AP later. If args are omitted, default tab stops are used.
24 .\" Start box enclosure. From here until next .BE, everything will be
25 .\" enclosed in one large box.
28 .\" End of box enclosure.
31 .\" Begin code excerpt.
36 .\" .VS ?version? ?br?
37 .\" Begin vertical sidebar, for use in marking newly-changed parts
38 .\" of man pages. The first argument is ignored and used for recording
39 .\" the version when the .VS was added, so that the sidebars can be
40 .\" found and removed when they reach a certain age. If another argument
41 .\" is present, then a line break is forced before starting the sidebar.
44 .\" End of vertical sidebar.
47 .\" Begin an indented unfilled display.
50 .\" End of indented unfilled display.
53 .\" Start of list of standard options for a Tk widget. The manpage
54 .\" argument defines where to look up the standard options; if
55 .\" omitted, defaults to "options". The options follow on successive
56 .\" lines, in three columns separated by tabs.
59 .\" End of list of standard options for a Tk widget.
61 .\" .OP cmdName dbName dbClass
62 .\" Start of description of a specific option. cmdName gives the
63 .\" option's name as specified in the class command, dbName gives
64 .\" the option's name in the option database, and dbClass gives
65 .\" the option's class in the option database.
68 .\" Print arg1 underlined, then print arg2 normally.
71 .\" Print arg1 in quotes, then arg2 normally (for trailing punctuation).
74 .\" Print an open parenthesis, arg1 in quotes, then arg2 normally
75 .\" (for trailing punctuation) and then a closing parenthesis.
77 .\" # Set up traps and other miscellaneous stuff for Tcl/Tk man pages.

283 \fBTcl_RecordAndEvalObj\fR(\fIinterp, cmdPtr, flags\fR)
285 .AS Tcl_Interp *interp
286 .AP Tcl_Interp *interp in
287 Tcl interpreter in which to evaluate command.
288 .AP Tcl_Obj *cmdPtr in
289 Points to a Tcl value containing a command (or sequence of commands)
292 An OR'ed combination of flag bits. \fBTCL_NO_EVAL\fR means record the
293 command but do not evaluate it. \fBTCL_EVAL_GLOBAL\fR means evaluate
294 the command at global level instead of the current stack level.
299 \fBTcl_RecordAndEvalObj\fR is invoked to record a command as an event
300 on the history list and then execute it using \fBTcl_EvalObjEx\fR
301 (or \fBTcl_GlobalEvalObj\fR if the \fBTCL_EVAL_GLOBAL\fR bit is set
303 It returns a completion code such as \fBTCL_OK\fR just like \fBTcl_EvalObjEx\fR,
304 as well as a result value containing additional information
305 (a result value or error message)
306 that can be retrieved using \fBTcl_GetObjResult\fR.
307 If you do not want the command recorded on the history list then
308 you should invoke \fBTcl_EvalObjEx\fR instead of \fBTcl_RecordAndEvalObj\fR.
309 Normally \fBTcl_RecordAndEvalObj\fR is only called with top-level
310 commands typed by the user, since the purpose of history is to
311 allow the user to re-issue recently invoked commands.
312 If the \fIflags\fR argument contains the \fBTCL_NO_EVAL\fR bit then
313 the command is recorded without being evaluated.
