.IP "[2] \fBEvaluation.\fR"
A command is evaluated in two steps.
First, the Tcl interpreter breaks the command into \fIwords\fR
and performs substitutions as described below.
These substitutions are performed in the same way for all
commands.
Secondly, the first word is used to locate a routine to
carry out the command, and the remaining words of the command are
passed to that routine.
The routine is free to interpret each of its words
in any way it likes, such as an integer, variable name, list,
or Tcl script.
Different commands interpret their words differently.
.IP "[3] \fBWords.\fR"
Words of a command are separated by white space (except for
newlines, which are command separators).
.IP "[4] \fBDouble quotes.\fR"

\fBTcl_UtfToLower\fR is the same as \fBTcl_UtfToUpper\fR except it
turns each character in the string into its lower-case equivalent.
.PP
\fBTcl_UtfToTitle\fR is the same as \fBTcl_UtfToUpper\fR except it
turns the first character in the string into its title-case equivalent
and all following characters into their lower-case equivalents.







.SH KEYWORDS
utf, unicode, toupper, tolower, totitle, case

sequence consists of a lead byte followed by some number of trail bytes.
.PP
\fBTCL_UTF_MAX\fR is the maximum number of bytes that it takes to
represent one Unicode character in the UTF-8 representation.
.PP
\fBTcl_UniCharToUtf\fR stores the character \fIch\fR as a UTF-8 string
in starting at \fIbuf\fR.  The return value is the number of bytes stored
in \fIbuf\fR. If ch is a high surrogate (range U+D800 - U+DBFF), then
the return value will be 1 and a single byte in the range 0xF0 - 0xF4
will be stored. If you still want to produce UTF-8 output for it (even
though knowing it's an illegal code-point on its own), just call
\fBTcl_UniCharToUtf\fR again specifying ch = -1.
.PP
\fBTcl_UtfToUniChar\fR reads one UTF-8 character starting at \fIsrc\fR
and stores it as a Tcl_UniChar in \fI*chPtr\fR.  The return value is the
number of bytes read from \fIsrc\fR.  The caller must ensure that the
source buffer is long enough such that this routine does not run off the
end and dereference non-existent or random memory; if the source buffer
is known to be null-terminated, this will not happen.  If the input is

\fBarray nextelement\fR will not indicate whether the search
has been completed.
.TP
\fBarray default \fIsubcommand arrayName args...\fR
.VS TIP508
Manages the default value of the array. Arrays initially have no default
value, but this command allows you to set one; the default value will be
returned when reading from an element of the array \fIarrayName\fR if the read
would otherwise result in an error. Note that this may cause the \fBappend\fR,
\fBdict\fR, \fBincr\fR and \fBlappend\fR commands to change their behavior in
relation to non-existing array elements.
.RS
.PP
The \fIsubcommand\fR argument controls what exact operation will be performed
on the default value of \fIarrayName\fR. Supported \fIsubcommand\fRs are:

\fB\-vacuumtrigger \fIdeletionCount\fR
.
A count of the number of persistent cookie deletions to go between vacuuming
the database.
.RE
.PP
Cookie jar instances may be made with any of the standard TclOO instance
creation methods (\fBcreate\fR or \fBnew\fR).
.TP
\fB::http::cookiejar new\fR ?\fIfilename\fR?
.
If a \fIfilename\fR argument is provided, it is the name of a file containing
an SQLite database that will contain the persistent cookies maintained by the
cookie jar; the database will be created if the file does not already
exist. If \fIfilename\fR is not supplied, the database will be held entirely within

This creates a class method, or (if \fIargList\fR and \fIbodyScript\fR are
omitted) promotes an existing method on the class object to be a class
method. The \fIname\fR, \fIargList\fR and \fIbodyScript\fR arguments are as in
the \fBmethod\fR definition, below.
.RS
.PP
Class methods can be called on either the class itself or on the instances of
that class. When they are called, the current object (see the \fBsel\fR and
\fBmy\fR commands) is the class on which they are called or the class of the
instance on which they are called, depending on whether they are called on the
class or an instance of the class, respectively. If called on a subclass or
instance of the subclass, the current object is the subclass.
.PP
In a private definition context, the methods as invoked on classes are
\fInot\fR private, but the methods as invoked on instances of classes are

.
Unary minus, unary plus, bit-wise NOT, logical NOT.  These operators
may only be applied to numeric operands, and bit-wise NOT may only be
applied to integers.
.TP 20
\fB**\fR
.
Exponentiation.  Valid for numeric operands.  The maximum exponent value
that Tcl can handle if the first number is an integer > 1 is 268435455.
.TP 20
\fB*\0\0/\0\0%\fR
.
Multiply and divide, which are valid for numeric operands, and remainder, which
is valid for integers.  The remainder, an absolute value smaller than the
absolute value of the divisor, has the same sign as the divisor.

.SH DESCRIPTION
.PP
Available commands:


.TP
\fBinfo args \fIprocname\fR
.
Returns the names of the parameters to the procedure named \fIprocname\fR.


.TP
\fBinfo body \fIprocname\fR
.
Returns the body of the procedure named \fIprocname\fR.

.TP
\fBinfo class\fI subcommand class\fR ?\fIarg ...\fR
.
Returns information about the class named \fIclass\fR.
See \fBCLASS INTROSPECTION\fR below.
.TP
\fBinfo cmdcount\fR
.

Returns the total number of commands evaluated in this interpreter.
.TP
\fBinfo cmdtype \fIcommandName\fR
.VS TIP426
Returns a the type of the command named \fIcommandName\fR.
Built-in types are:
.RS
.IP \fBalias\fR
\fIcommandName\fR was created by \fBinterp alias\fR.
In a safe interpreter an alias is only visible if both the alias and the
target are visible.
.IP \fBcoroutine\fR
\fIcommandName\fR was created by \fBcoroutine\fR.
.IP \fBensemble\fR
\fIcommandName\fR was created by \fBnamespace ensemble\fR.
.IP \fBimport\fR
\fIcommandName\fR was created by \fBnamespace import\fR.
.IP \fBnative\fR
\fIcommandName\fR was created by the \fBTcl_CreateObjProc\fR
interface directly without further registration of the type of command.
.IP \fBobject\fR
\fIcommandName\fR is the public command that represents an
instance of \fBoo::object\fR or one of its subclasses.
.IP \fBprivateObject\fR
\fIcommandName\fR is the private command, \fBmy\fR by default,
that represents an instance of \fBoo::object\fR or one of its subclasses.
.IP \fBproc\fR
\fIcommandName\fR was created by \fBproc\fR.
.IP \fBslave\fR
\fIcommandName\fR was created by \fBinterp create\fR.
.IP \fBzlibStream\fR
\fIcommandName\fR was created by \fBzlib stream\fR.
.PP

Other types may be also registered as well.  See \fBTcl_RegisterCommandTypeName\fR.
.RE
.VE TIP426
.TP
\fBinfo commands \fR?\fIpattern\fR?
.

Returns the names of all commands visible in the current namespace.  If



\fIpattern\fR is given, returns only those names that match according to







\fBstring match\fR.  Only the last component of \fIpattern\fR is a pattern.


Other components identify a namespace.  See \fBNAMESPACE RESOLUTION\fR in the
\fBnamespace\fR(n) documentation.


.TP
\fBinfo complete \fIcommand\fR
.
Returns 1 if \fIcommand\fR is a complete command, and \fB0\fR otherwise.


Typically used in line-oriented input environments
to allow users to type in commands that span multiple lines.


.TP
\fBinfo coroutine\fR
.
Returns the name of the current \fBcoroutine\fR, or the empty
string if there is no current coroutine or the current coroutine
has been deleted.
.TP
\fBinfo default \fIprocname parameter varname\fR
.
If the parameter \fIparameter\fR for the procedure named \fIprocname\fR has a

default value, stores that value in \fIvarname\fR and returns \fB1\fR.
Otherwise, returns \fB0\fR.

.TP
\fBinfo errorstack \fR?\fIinterp\fR?
.
Returns a description of the active command at each level for the
last error in the current interpreter, or in the interpreter named
\fIinterp\fR if given.
.RS
.PP
The description is a dictionary of tokens and parameters. Tokens are
currently either \fBCALL\fR, \fBUP\fR, or \fBINNER\fR, but other values may be
introduced in the future. \fBCALL\fR indicates a command call, and its
parameter is the corresponding \fBinfo level\fR \fB0\fR. \fBUP\fR indicates a
shift in variable frames generated by \fBuplevel\fR or similar, and applies to
the previous \fBCALL\fR item. Its parameter is the level offset. \fBINNER\fR
identifies the
.QW "inner context" ,
which is the innermost atomic command or bytecode instruction that raised the
error, along with its arguments when available. While \fBCALL\fR and \fBUP\fR
provide a trail of the call path, \fBINNER\fR provides details of the offending
operation in the innermost procedure call, even to sub-expression
granularity.
.PP
This information is also present in the \fB\-errorstack\fR entry of the
options dictionary returned by 3-argument \fBcatch\fR; \fBinfo errorstack\fR
is a convenient way of retrieving it for uncaught errors at top-level in an
interactive \fBinterpreter\fR.
.RE
.TP
\fBinfo exists \fIvarName\fR
.
Returns \fB1\fR if a variable named \fIvarName\fR is visible and has been

defined, and \fB0\fR otherwise.
.TP
\fBinfo frame\fR ?\fIdepth\fR?
.
Returns the depth of the call to \fBinfo frame\fR itself.  Otherwise, returns a
dictionary describing the active command at the \fIdepth\fR, which counts all
commands visible to \fBinfo level\fR, plus commands that don't create a new
level, such as \fBeval\fR, \fBsource\fR, or \fIuplevel\fR. The frame depth is

always greater than the current level.

.RS
.PP


If \fIdepth\fR is greater than \fB0\fR it is the frame at that depth.  Otherwise
it is the number of frames up from the current frame.



.PP
As with \fBinfo level\fR and error traces, for nested commands like




.QW "foo [bar [x]]" ,
only
.QW x
is seen by \fBinfo frame\fR invoked within
.QW x .

.PP
The dictionary may contain the following keys:

.TP
\fBtype\fR
.

Always present.  Possible values are \fBsource\fR, \fBproc\fR,
\fBeval\fR, and \fBprecompiled\fR.
.RS
.TP
\fBsource\fR\0\0\0\0\0\0\0\0
.
A script loaded via the \fBsource\fR
command.
.TP
\fBproc\fR\0\0\0\0\0\0\0\0
.
The body of a procedure that could not be traced back to a
line in a particular script.
.TP
\fBeval\fR\0\0\0\0\0\0\0\0
.
The body of a script provided to \fBeval\fR or \fBuplevel\fR.
.TP
\fBprecompiled\fR\0\0\0\0\0\0\0\0
.
A pre-compiled script (loadable by the package
\fBtbcload\fR), and no further information is available.

.RE
.TP
\fBline\fR
.
The line number of of the command inside its script.  Not available for

\fBprecompiled\fR commands.  When the type is \fBsource\fR, the line number is
relative to the beginning of the file, whereas for the last two types it is
relative to the start of the script.
.TP
\fBfile\fR
.
For type \fBsource\fR, provides the normalized path of the file that contains
the command.
.TP
\fBcmd\fR
.
The command before substitutions were performed.





.TP
\fBproc\fR
.

For type \fBprod\fR, the name of the procedure containing the command.
.TP
\fBlambda\fR
.
For a command in a script evaluated as the body of an unnamed routine via the

\fBapply\fR command, the definition of that routine.
.TP
\fBlevel\fR
.
For a frame that corresponds to a level, (to be determined).


.PP

When a command can be traced to its literal definition in some script, e.g.

procedures nested in statically defined procedures, and literal eval scripts in
files or statically defined procedures, its type is \fBsource\fR and its
location is the absolute line number in the script.  Otherwise, its type is
\fBproc\fR and its location is its line number within the body of the
procedure.
.PP
In contrast, procedure definitions and \fBeval\fR within a dynamically
\fBeval\fRuated environment count line numbers relative to the start of
their script, even if they would be able to count relative to the
start of the outer dynamic script. That type of number usually makes
more sense.
.PP
A different way of describing this behaviour is that file-based
locations are tracked as deeply as possible, and where this is not
possible the lines are counted based on the smallest possible
\fBeval\fR or procedure body, as that scope is usually easier to find
than any dynamic outer scope.
.PP
The syntactic form \fB{*}\fR is handled like \fBeval\fR. I.e. if it
is given a literal list argument the system tracks the line number
within the list words as well, and otherwise all line numbers are
counted relative to the start of each word (smallest scope)

.TP
\fBinfo functions \fR?\fIpattern\fR?
.
If \fIpattern\fR is not given, returns a list of all the math
functions currently defined.
If \fIpattern\fR is given, returns only those names that match

\fIpattern\fR according to \fBstring match\fR.
.TP
\fBinfo globals \fR?\fIpattern\fR?
.
If \fIpattern\fR is not given, returns a list of all the names
of currently-defined global variables.
Global variables are variables in the global namespace.
If \fIpattern\fR is given, only those names matching \fIpattern\fR
are returned.  Matching is determined using the same rules as for
\fBstring match\fR.
.TP
\fBinfo hostname\fR
.
Returns the name of the current host.

This name is not guaranteed to be the fully-qualified domain
name of the host.  Where machines have several different names, as is
common on systems with both TCP/IP (DNS) and NetBIOS-based networking
installed, it is the name that is suitable for TCP/IP networking that
is returned.
.TP
\fBinfo level\fR ?\fIlevel\fR?
.
If \fInumber\fR is not given, the level this routine was called from.

Otherwise returns the complete command active at the given level.  If

\fInumber\fR is greater than \fB0\fR, it is the desired level.  Otherwise, it


is \fInumber\fR levels up from the current level.  A complete command is the

words in the command, with all subsitutions performed, meaning that it is a
list.  See \fBuplevel\fR for more information on levels.

directory in which the scripts distributed with Tcl scripts are stored.


.TP
\fBinfo loaded \fR?\fIinterp\fR? ?\fIpackage\fR?
.
Returns the name of each file loaded in \fIinterp\fR va \fBload\fR as part of
\fIpackage\fR .  If \fIpackage\fR is not given, returns a list where each item



is the name of the loaded file and the name of the package for which the file
was loaded.  For a statically-loaded package the name of the file is the empty


string.  For \fInterp\fR, the empty string is the current interpreter.

.TP
\fBinfo locals \fR?\fIpattern\fR?
.
If \fIpattern\fR is given, returns the name of each local variable matching


\fIpattern\fR according to \fBstring match\fR.  Otherwise, returns the name of
each local variable.  A variables defined with the \fBglobal\fR, \fBupvar\fR or
\fBvariable\fR is not local.

exact version of the Tcl library initially stored.
.TP
\fBinfo procs \fR?\fIpattern\fR?
.


Returns the names of all visible procedures. If \fIpattern\fR is given, returns



only those names that match according to \fBstring match\fR.  Only the final
component in \fIpattern\fR is actually considered a pattern.  Any qualifying
components simply select a namespace.  See \fBNAMESPACE RESOLUTION\fR in the


\fBnamespace\fR(n) documentation.
.TP
\fBinfo script\fR ?\fIfilename\fR?
.
Returns the pathname of the innermost script currently being evaluated, or the


empty string if no pathname can be determined.  If \fIfilename\fR is given,
sets the return value of any future calls to \fBinfo script\fR for the duration
of the innermost active script.  This is useful in virtual file system
applications.

.TP
\fBinfo sharedlibextension\fR
.
Returns the extension used on this platform for names of shared libraries, e.g.
\fB.so\fR under Solaris.  Returns the empty string if shared libraries are not
supported on this platform.

.TP
\fBinfo tclversion\fR
.
Returns the value of the global variable \fBtcl_version\fR, in which the
major and minor version of the Tcl library are stored.
.TP
\fBinfo vars\fR ?\fIpattern\fR?
.
If \fIpattern\fR is not given, returns the names of all visible variables.  If


\fIpattern\fR is given, returns only those names that match according to

\fBstring match\fR.  Only the last component of \fIpattern\fR is a pattern.





Other components identify a namespace.  See \fBNAMESPACE RESOLUTION\fR in the
\fBnamespace\fR(n) documentation.  When \fIpattern\fR is a qualified name,

results are fully qualified.




A variable that has declared but not yet defined is included in the results.

.SH DESCRIPTION
.PP
The first and second form will evaluate \fIscript\fR until the interval
\fItime\fR given in milliseconds elapses, or for 1000 milliseconds (1 second)
if \fItime\fR is not specified.
.sp
The parameter \fImax-count\fR could additionally impose a further restriction
by the maximal number of iterations to evaluate the script.
If \fImax-count\fR is specified, the evalution will stop either this count of
iterations is reached or the time is exceeded.
.sp
It will then return a canonical tcl-list of the form

which indicates:
.IP \(bu
the average amount of time required per iteration, in microseconds ([\fBlindex\fR $result 0])
.IP \(bu
the count how many times it was executed ([\fBlindex\fR $result 2])
.IP \(bu
the estimated rate per second ([\fBlindex\fR $result 4])
.IP \(bu
the estimated real execution time without measurement overhead ([\fBlindex\fR $result 6])
.PP
Time is measured in elapsed time using the finest timer resolution as possible,
not CPU time.
This command may be used to provide information as to how well the script or a
tcl-command is performing and can help determine bottlenecks and fine-tune
application performance.
.TP
\fI-calibrate\fR
.
To measure very fast scripts as exact as posible the calibration process
may be required.

The \fI-calibrate\fR option is used to calibrate timerate, calculating the
estimated overhead of the given script as the default overhead for future
invocations of the \fBtimerate\fR command. If the \fItime\fR parameter is not
specified, the calibrate procedure runs for up to 10 seconds.
.TP
\fI-overhead double\fR
.
The \fI-overhead\fR parameter supplies an estimate (in microseconds) of the
measurement overhead of each iteration of the tested script. This quantity
will be subtracted from the measured time prior to reporting results.
.TP
\fI-direct\fR
.
The \fI-direct\fR option causes direct execution of the supplied script,
without compilation, in a manner similar to the \fBtime\fR command. It can be
used to measure the cost of \fBTcl_EvalObjEx\fR, of the invocation of canonical
lists, and of the uncompiled versions of bytecoded commands.
.PP
As opposed to the \fBtime\fR commmand, which runs the tested script for a fixed
number of iterations, the timerate command runs it for a fixed time.
Additionally, the compiled variant of the script will be used during the entire
measurement, as if the script were part of a compiled procedure, if the \fI-direct\fR
option is not specified. The fixed time period and possibility of compilation allow
for more precise results and prevent very long execution times by slow scripts, making
it practical for measuring scripts with highly uncertain execution times.

.SH EXAMPLE
Estimate how fast it takes for a simple Tcl \fBfor\fR loop (including
operations on variable \fIi\fR) to count to a ten:
.PP
.CS
# calibrate:
timerate -calibrate {}
# measure:
timerate { for {set i 0} {$i<10} {incr i} {} } 5000
.CE
.PP
Estimate how fast it takes for a simple Tcl \fBfor\fR loop, ignoring the
overhead for to perform ten iterations, ignoring the overhead of the management
of the variable that controls the loop:
.PP
.CS
# calibrate for overhead of variable operations:
set i 0; timerate -calibrate {expr {$i<10}; incr i} 1000
# measure:
timerate { for {set i 0} {$i<10} {incr i} {} } 5000
.CE
.PP
Estimate the speed of calculating the hour of the day using \fBclock format\fR only,
ignoring overhead of the portion of the script that prepares the time for it to
calculate:
.PP
.CS
# calibrate:
timerate -calibrate {}
# estimate overhead:
set tm 0
set ovh [lindex [timerate { incr tm [expr {24*60*60}] }] 0]
# measure using esimated overhead:
set tm 0
timerate -overhead $ovh {
    clock format $tm -format %H
    incr tm [expr {24*60*60}]; # overhead for this is ignored
