.SH DESCRIPTION
.PP
This series of C functions provides an interface whereby commands that
are implemented in C can be evaluated, and invoke Tcl commands scripts
and scripts, without consuming space on the C stack. The non-recursive
evaluation is done by installing a \fItrampoline\fR, a small piece of
code that invokes a command or script, and then executes a series of
callbacks when the command or script returns.





.PP
The \fBTcl_NRCreateCommand\fR function creates a Tcl command in the
interpreter designated by \fIinterp\fR that is prepared to handle
nonrecursive evaluation with a trampoline. The \fIcmdName\fR argument
gives the name of the new command. If \fIcmdName\fR contains any
namespace qualifiers, then the new command is added to the specified
namespace; otherwise, it is added to the global namespace. \fIproc\fR
gives the procedure that will be called when the interpreter wishes to
evaluate the command in an unoptimized manner, and \fInreProc\fR is
the procedure that will be called when the interpreter wishes to
evaluate the command using a trampoline. \fIdeleteProc\fR is a
function that will be called before the command is deleted from the
interpreter. When any of the three functions is invoked, it is passed
the \fIclientData\fR parameter.
.PP
\fBTcl_NRCreateCommand\fR deletes any existing command
\fIname\fR already associated with the interpreter
(however see below for an exception where the existing command
is not deleted).
It returns a token that may be used to refer


to the command in subsequent calls to \fBTcl_GetCommandName\fR.
If \fBTcl_NRCreateCommand\fR is called for an interpreter that is in

the process of being deleted, then it does not create a new command,

does not delete any existing command of the same name, and returns NULL.
.PP
The \fIproc\fR and \fInreProc\fR function are expected to conform to
all the rules set forth for the \fIproc\fR argument to
\fBTcl_CreateObjCommand\fR(3) (\fIq.v.\fR).


.PP
When a command that is written to cope with evaluation via trampoline
is invoked without a trampoline on the stack, it will usually respond
to the invocation by creating a trampoline and calling the
trampoline-enabled implementation of the same command. This call is done by
means of \fBTcl_NRCallObjProc\fR. In the call to
\fBTcl_NRCallObjProc\fR, the \fIinterp\fR, \fIclientData\fR,
\fIobjc\fR and \fIobjv\fR parameters should be the same ones that were
passed to \fIproc\fR. The \fInreProc\fR parameter should designate the
trampoline-enabled implementation of the command.
.PP
\fBTcl_NREvalObj\fR arranges for the script contained in \fIobjPtr\fR
to be evaluated in the interpreter designated by \fIinterp\fR after
the current command (which must be trampoline-enabled) returns. It is
the method by which a command may invoke a script without consuming

space on the C stack. Similarly, \fBTcl_NREvalObjv\fR arranges to
invoke a single Tcl command whose words have already been separated
and substituted. The \fIobjc\fR and \fIobjv\fR parameters give the
words of the command to be evaluated when execution reaches the
trampoline.
.PP
\fBTcl_NRCmdSwap\fR allows for trampoline evaluation of a command whose
resolution is already known.  The \fIcmd\fR parameter gives a

\fBTcl_Command\fR token (returned from \fBTcl_CreateObjCommand\fR or
\fBTcl_GetCommandFromObj\fR) identifying the command to be invoked in
the trampoline; this command must match the word in \fIobjv[0]\fR.
The remaining arguments are as for \fBTcl_NREvalObjv\fR.

.PP
\fBTcl_NREvalObj\fR, \fBTcl_NREvalObjv\fR and \fBTcl_NRCmdSwap\fR
all accept a \fIflags\fR parameter, which is an OR-ed-together set of
bits to control evaluation. At the present time, the only supported flag
available to callers is \fBTCL_EVAL_GLOBAL\fR.
.\" TODO: Again, this is a lie. Do we want to explain TCL_EVAL_INVOKE
.\"       and TCL_EVAL_NOERR?
If the \fBTCL_EVAL_GLOBAL\fR flag is set, the script or command is
evaluated in the global namespace. If it is not set, it is evaluated
in the current namespace.



.PP
\fBTcl_NRExprObj\fR arranges for the expression contained in \fIobjPtr\fR
to be evaluated in the interpreter designated by \fIinterp\fR after
the current command (which must be trampoline-enabled) returns. It is
the method by which a command may evaluate a Tcl expression without consuming
space on the C stack.  The argument \fIresultPtr\fR is a pointer to an
unshared Tcl_Obj where the result of expression evaluation is to be written.
If expression evaluation returns any code other than TCL_OK, the
\fIresultPtr\fR value is left untouched.
.PP
All of the routines return \fBTCL_OK\fR if command or expression invocation

has been scheduled successfully. If for any reason the scheduling cannot
be completed (for example, if the interpreter is unable to find
the requested command), they return \fBTCL_ERROR\fR with an
appropriate message left in the interpreter's result.
.PP
\fBTcl_NRAddCallback\fR arranges to have a C function called when the
current trampoline-enabled command in the Tcl interpreter designated
by \fIinterp\fR returns.  The \fIpostProcPtr\fR argument is a pointer
to the callback function, which must have arguments and return value

consistent with the \fBTcl_NRPostProc\fR data type:
.PP
.CS
typedef int
\fBTcl_NRPostProc\fR(
        \fBClientData\fR \fIdata\fR[],
        \fBTcl_Interp\fR *\fIinterp\fR,
        int \fIresult\fR);
.CE
.PP
When the trampoline invokes the callback function, the \fIdata\fR
parameter will point to an array containing the four one-word
quantities that were passed to \fBTcl_NRAddCallback\fR in the
\fIdata0\fR through \fIdata3\fR parameters. The Tcl interpreter will
be designated by the \fIinterp\fR parameter, and the \fIresult\fR
parameter will contain the result (\fBTCL_OK\fR, \fBTCL_ERROR\fR,
\fBTCL_RETURN\fR, \fBTCL_BREAK\fR or \fBTCL_CONTINUE\fR) that was
returned by the command evaluation. The callback function is expected,
in turn, either to return a \fIresult\fR to control further evaluation.
.PP
Multiple \fBTcl_NRAddCallback\fR invocations may request multiple
callbacks, which may be to the same or different callback
functions. If multiple callbacks are requested, they are executed in
last-in, first-out order, that is, the most recently requested
callback is executed first.
.SH EXAMPLE
.PP
The usual pattern for Tcl commands that invoke other Tcl commands
is something like:


.PP
.CS
int
\fITheCmdOldObjProc\fR(
    ClientData clientData,
    Tcl_Interp *interp,
    int objc,
................................................................................

    return result;
}
\fBTcl_CreateObjCommand\fR(interp, "theCommand",
        \fITheCmdOldObjProc\fR, clientData, TheCmdDeleteProc);
.CE
.PP
To enable a command like this one for trampoline-based evaluation,
it must be split into three pieces:
.IP \(bu
A non-trampoline implementation, \fITheCmdNewObjProc\fR,
which will simply create a trampoline
and invoke the trampoline-based implementation.
.IP \(bu
A trampoline-enabled implementation, \fITheCmdNRObjProc\fR.  This
function will perform the initialization, request that the trampoline
call the postprocessing routine after command evaluation, and finally,
request that the trampoline call the inner command.
.IP \(bu
A postprocessing routine, \fITheCmdPostProc\fR. This function will
perform the postprocessing formerly done after the return from the
inner command in \fITheCmdObjProc\fR.
.PP
The non-trampoline implementation is simple and stylized, containing
a single statement:
.PP
.CS
int
\fITheCmdNewObjProc\fR(
    ClientData clientData,
    Tcl_Interp *interp,
    int objc,
    Tcl_Obj *const objv[])
{
    return \fBTcl_NRCallObjProc\fR(interp, \fITheCmdNRObjProc\fR,
            clientData, objc, objv);
}
.CE
.PP
The trampoline-enabled implementation requests postprocessing,
and returns to the trampoline requesting command evaluation.
.PP
.CS
int
\fITheCmdNRObjProc\fR
    ClientData clientData,
    Tcl_Interp *interp,
    int objc,
    Tcl_Obj *const objv[])
................................................................................
    /* \fIdata0 .. data3\fR are up to four one-word items to
     * pass to the postprocessing procedure */

    return \fBTcl_NREvalObj\fR(interp, objPtr, 0);
}
.CE
.PP
The postprocessing procedure does whatever the original command did
upon return from the inner evaluation.
.PP
.CS
int
\fITheCmdNRPostProc\fR(
    ClientData data[],
    Tcl_Interp *interp,
    int result)
{
................................................................................

    \fI... postprocessing ...\fR

    return result;
}
.CE
.PP
If \fItheCommand\fR is a command that results in multiple commands or
scripts being evaluated, its postprocessing routine may schedule
additional postprocessing and then request another command evaluation
by means of \fBTcl_NREvalObj\fR or one of the other evaluation
routines. Looping and sequencing constructs may be implemented in this way.
.PP
Finally, to install a trampoline-enabled command in the interpreter,
\fBTcl_NRCreateCommand\fR is used in place of
\fBTcl_CreateObjCommand\fR.  It accepts two command procedures instead
of one. The first is for use when no trampoline is yet on the stack,
and the second is for use when there is already a trampoline in place.
.PP
.CS
\fBTcl_NRCreateCommand\fR(interp, "theCommand",
        \fITheCmdNewObjProc\fR, \fITheCmdNRObjProc\fR, clientData,
        TheCmdDeleteProc);

Name of the command to create.
.AP Tcl_ObjCmdProc *proc in
Called in order to evaluate a command.  Is often just a small wrapper that uses

Arbitrary one-word value passed to \fIproc\fR, \fInreProc\fR, \fIdeleteProc\fR
and \fIobjProc\fR.
.AP Tcl_CmdDeleteProc *deleteProc in/out
Called before \fIcmdName\fR is deleted from the interpreter, allowing for
command-specific cleanup. May be NULL.

.BE
.SH DESCRIPTION
.PP
These functions provide an interface to the function stack that an interpreter
iterates through to evaluate commands.  The routine behind a command is
implemented by an initial function and any additional functions that the
routine pushes onto the stack as it progresses.  The interpreter itself pushes
functions onto the stack to react to the end of a routine and to exercise other
forms of control such as switching between in-progress stacks and the
evaluation of other scripts at additional levels without adding frames to the C
stack.  To execute a routine, the initial function for the routine is called
and then a small bit of code called a \fItrampoline\fR iteratively takes
functions off the stack and calls them, using the value of the last call as the
value of the routine.
.PP





\fBTcl_NRCallObjProc\fR calls \fInreProc\fR using a new trampoline.







.PP
\fBTcl_NRCreateCommand\fR, an alternative to \fBTcl_CreateObjCommand\fR,




resolves \fIcmdName\fR, which may contain namespace qualifiers, relative to the
current namespace, creates a command by that name, and returns a token for the
command which may be used in subsequent calls to \fBTcl_GetCommandName\fR.

Except for a few cases noted below any existing command by the same name is
first deleted.  If \fIinterp\fR is in the process of being deleted
\fBTcl_NRCreateCommand\fR does not create any command, does not delete any
command, and returns NULL.
.PP



\fBTcl_NREvalObj\fR pushes a function that is like \fBTcl_EvalObjEx\fR but
consumes no space on the C stack.
.PP














\fBTcl_NREvalObjv\fR pushes a function that is like \fBTcl_EvalObjv\fR but
consumes no space on the C stack.




.PP


\fBTcl_NRCmdSwap\fR is like \fBTcl_NREvalObjv\fR, but uses \fIcmd\fR, a token
previously returned by \fBTcl_CreateObjCommand\fR or
\fBTcl_GetCommandFromObj\fR, instead of resolving the first word of \fIobjv\fR.


.  The name of this command must be the same as \fIobjv[0]\fR.
.PP









\fBTcl_NRExprObj\fR pushes a function that evaluates \fIobjPtr\fR as an
expression in the same manner as \fBTcl_ExprObj\fR but without consuming space
on the C stack.
.PP










All of the functions return \fBTCL_OK\fR if the evaluation of the script,
command, or expression has been scheduled successfully.  Otherwise (for example

if the command name cannot be resolved), they return \fBTCL_ERROR\fR and store
a message as the interpreter's result.
.PP




\fBTcl_NRAddCallback\fR pushes \fIpostProcPtr\fR.  The signature for
\fBTcl_NRPostProc\fR is:
.PP
.CS
typedef int
\fBTcl_NRPostProc\fR(
        \fBClientData\fR \fIdata\fR[],
        \fBTcl_Interp\fR *\fIinterp\fR,
        int \fIresult\fR);
.CE
.PP
\fIdata\fR is a pointer to an array containing \fIdata0\fR through \fIdata3\fR.
\fIresult\fR is the value returned by the previous function implementing part
the routine.












.SH EXAMPLE
.PP


The following command uses \fBTcl_EvalObjEx\fR, which consumes space on the C
stack, to evalute a script:
.PP
.CS
int
\fITheCmdOldObjProc\fR(
    ClientData clientData,
    Tcl_Interp *interp,
    int objc,
................................................................................

    return result;
}
\fBTcl_CreateObjCommand\fR(interp, "theCommand",
        \fITheCmdOldObjProc\fR, clientData, TheCmdDeleteProc);
.CE
.PP
To avoid consuming space on the C stack, \fITheCmdOldObjProc\fR is renamed to
\fITheCmdNRObjProc\fR and the postprocessing step is split into a separate
function, \fITheCmdPostProc\fR, which is pushed onto the function stack.
\fITcl_EvalObjEx\fR is replaced with \fITcl_NREvalObj\fR, which uses a
trampoline instead of consuming space on the C stack.  A new version of
\fITheCmdOldObjProc\fR is just a a wrapper that uses \fBTcl_NRCallObjProc\fR to

call \fITheCmdNRObjProc\fR:







.PP



.CS
int
\fITheCmdOldObjProc\fR(
    ClientData clientData,
    Tcl_Interp *interp,
    int objc,
    Tcl_Obj *const objv[])
{
    return \fBTcl_NRCallObjProc\fR(interp, \fITheCmdNRObjProc\fR,
            clientData, objc, objv);
}
.CE
.PP



.CS
int
\fITheCmdNRObjProc\fR
    ClientData clientData,
    Tcl_Interp *interp,
    int objc,
    Tcl_Obj *const objv[])
................................................................................
    /* \fIdata0 .. data3\fR are up to four one-word items to
     * pass to the postprocessing procedure */

    return \fBTcl_NREvalObj\fR(interp, objPtr, 0);
}
.CE
.PP



.CS
int
\fITheCmdNRPostProc\fR(
    ClientData data[],
    Tcl_Interp *interp,
    int result)
{
................................................................................

    \fI... postprocessing ...\fR

    return result;
}
.CE
.PP
Any function comprising a routine can push other functions, making it possible



implement looping and sequencing constructs using the function stack.

\fB#\fR
Requests an alternate output form. For \fBo\fR

If the precision is specified with \fB*\fR rather than a number

it must be a numeric string.
.SS "OPTIONAL SIZE MODIFIER"
.PP
The fifth part of a conversion specifier is a size modifier,
which must be \fBll\fR, \fBh\fR, or \fBl\fR.
If it is \fBll\fR it specifies that an integer value is taken
without truncation for conversion to a formatted substring.
If it is \fBh\fR it specifies that an integer value is
truncated to a 16-bit range before converting.  This option is rarely useful.
If it is \fBl\fR it specifies that the integer value is
truncated to the same range as that produced by the \fBwide()\fR
function of the \fBexpr\fR command (at least a 64-bit range).


If neither \fBh\fR nor \fBl\fR are present, the integer value is
truncated to the same range as that produced by the \fBint()\fR
function of the \fBexpr\fR command (at least a 32-bit range, but
determined by the value of the \fBwordSize\fR element of the
\fBtcl_platform\fR array).
.SS "MANDATORY CONVERSION TYPE"
.PP
The last thing in a conversion specifier is an alphabetic character
................................................................................
\fBg\fR or \fBG\fR
If the exponent is less than \-4 or greater than or equal to the
precision, then convert number as for \fB%e\fR or
\fB%E\fR.
Otherwise convert as for \fB%f\fR.
Trailing zeroes and a trailing decimal point are omitted.
.TP 10







\fB%\fR
No conversion: just insert \fB%\fR.




.SH "DIFFERENCES FROM ANSI SPRINTF"
.PP
The behavior of the format command is the same as the
ANSI C \fBsprintf\fR procedure except for the following
differences:
.IP [1]
Tcl guarantees that it will be working with UNICODE characters.
.IP [2]
\fB%p\fR and \fB%n\fR specifiers are not supported.
.IP [3]
For \fB%c\fR conversions the argument must be an integer value,
which will then be converted to the corresponding character value.
.IP [4]
The size modifiers are ignored when formatting floating-point values.
The \fBll\fR modifier has no \fBsprintf\fR counterpart.
The \fBb\fR specifier has no \fBsprintf\fR counterpart.

This option implies \fB\-sorted\fR and cannot be used with either \fB\-all\fR
or \fB\-not\fR.
.VE 8.6
.SS "NESTED LIST OPTIONS"
.PP
These options are used to search lists of lists.  They may be used
with any other options.
.TP
\fB\-stride\0\fIstrideLength\fR
.
If this option is specified, the list is treated as consisting of
groups of \fIstrideLength\fR elements and the groups are searched by
either their first element or, if the \fB\-index\fR option is used,
by the element within each group given by the first index passed to
\fB\-index\fR (which is then ignored by \fB\-index\fR). The resulting
index always points to the first element in a group.
.PP
The list length must be an integer multiple of \fIstrideLength\fR, which
in turn must be at least 1. A \fIstrideLength\fR of 1 is the default and
indicates no grouping.
.TP
\fB\-index\fR\0\fIindexList\fR
.
This option is designed for use when searching within nested lists.
The \fIindexList\fR argument gives a path of indices (much as might be
used with the \fBlindex\fR or \fBlset\fR commands) within each element
to allow the location of the term being matched against.
................................................................................
.PP
It is also possible to search inside elements:
.PP
.CS
\fBlsearch\fR -index 1 -all -inline {{a abc} {b bcd} {c cde}} *bc*
      \fI\(-> {a abc} {b bcd}\fR
.CE
.PP
The same thing for a flattened list:
.PP
.CS
\fBlsearch\fR -stride 2 -index 1 -all -inline {a abc b bcd c cde} *bc*
      \fI\(-> {a abc b bcd}\fR

.BE
.SH DESCRIPTION
.PP
The \fBmsgcat\fR package provides a set of functions
that can be used to manage multi-lingual user interfaces.
Text strings are defined in a
.QW "message catalog"
................................................................................
Each package has its own message catalog and configuration settings in \fBmsgcat\fR.
.PP
A \fIlocale\fR is a specification string describing a user language like \fBde_ch\fR for Swiss German.
In \fBmsgcat\fR, there is a global locale initialized by the system locale of the current system.
Each package may decide to use the global locale or to use a package specific locale.
.PP
The global locale may be changed on demand, for example by a user initiated language change or within a multi user application like a web server.





.SH COMMANDS
.TP
\fB::msgcat::mc \fIsrc-string\fR ?\fIarg arg ...\fR?
.
Returns a translation of \fIsrc-string\fR according to the
current locale.  If additional arguments past \fIsrc-string\fR
are given, the \fBformat\fR command is used to substitute the
................................................................................
\fB::msgcat::mc\fR is the main function used to localize an
application.  Instead of using an English string directly, an
application can pass the English string through \fB::msgcat::mc\fR and
use the result.  If an application is written for a single language in
this fashion, then it is easy to add support for additional languages
later simply by defining new message catalog entries.
.RE











.TP
\fB::msgcat::mcmax ?\fIsrc-string src-string ...\fR?
.
Given several source strings, \fB::msgcat::mcmax\fR returns the length
of the longest translated string.  This is useful when designing
localized GUIs, which may require that all buttons, for example, be a
fixed width (which will be the width of the widest button).
.TP
\fB::msgcat::mcexists\fR ?\fB-exactnamespace\fR? ?\fB-exactlocale\fR? \fIsrc-string\fR
.
.VS "TIP 412"
Return true, if there is a translation for the given \fIsrc-string\fR.
.PP
.RS
The search may be limited by the option \fB\-exactnamespace\fR to only check the current namespace and not any parent namespaces.
.PP
It may also be limited by the option \fB\-exactlocale\fR to only check the first prefered locale (e.g. first element returned by \fB::msgcat::mcpreferences\fR if global locale is used).





.RE

.VE "TIP 412"

.TP

























\fB::msgcat::mclocale \fR?\fInewLocale\fR?
.
This function sets the locale to \fInewLocale\fR.  If \fInewLocale\fR
is omitted, the current locale is returned, otherwise the current locale










is set to \fInewLocale\fR.  msgcat stores and compares the locale in a
case-insensitive manner, and returns locales in lowercase.
The initial locale is determined by the locale specified in
the user's environment.  See \fBLOCALE SPECIFICATION\fR
below for a description of the locale string format.
.RS
.PP
.VS "TIP 412"
If the locale is set, the preference list of locales is evaluated.
Locales in this list are loaded now, if not jet loaded.
.VE "TIP 412"
.RE
.TP
\fB::msgcat::mcpreferences\fR
.
Returns an ordered list of the locales preferred by
the user, based on the user's language specification.
The list is ordered from most specific to least
preference.  The list is derived from the current
locale set in msgcat by \fB::msgcat::mclocale\fR, and
cannot be set independently.  For example, if the







current locale is en_US_funky, then \fB::msgcat::mcpreferences\fR
returns \fB{en_us_funky en_us en {}}\fR.




.TP
\fB::msgcat:mcloadedlocales subcommand\fR ?\fIlocale\fR?
.
This group of commands manage the list of loaded locales for packages not setting a package locale.
.PP
.RS
The subcommand \fBget\fR returns the list of currently loaded locales.
................................................................................
Note that this routine is only called if the concerned package did not set a package locale unknown command name.
.RE
.TP
\fB::msgcat::mcforgetpackage\fR
.
The calling package clears all its state within the \fBmsgcat\fR package including all settings and translations.
.VE "TIP 412"
















.PP
.SH "LOCALE SPECIFICATION"
.PP
The locale is specified to \fBmsgcat\fR by a locale string
passed to \fB::msgcat::mclocale\fR.
The locale string consists of
a language code, an optional country code, and an optional
................................................................................
.PP
.CS
\fBmsgcat::mc\fR {Produced %1$d at %2$s} $num $city
# ... where that key is mapped to one of the
# human-oriented versions by \fBmsgcat::mcset\fR
.CE
.VS "TIP 412"
.SH Package private locale
.PP
A package using \fBmsgcat\fR may choose to use its own package private
locale and its own set of loaded locales, independent to the global
locale set by \fB::msgcat::mclocale\fR.
.PP
This allows a package to change its locale without causing any locales load or removal in other packages and not to invoke the global locale change callback (see below).
.PP
................................................................................
This command may cause the load of locales.
.RE
.TP
\fB::msgcat::mcpackagelocale get\fR
.
Return the package private locale or the global locale, if no package private locale is set.
.TP
\fB::msgcat::mcpackagelocale preferences\fR
.
Return the package private preferences or the global preferences,
if no package private locale is set.












.TP
\fB::msgcat::mcpackagelocale loaded\fR
.
Return the list of locales loaded for this package.
.TP
\fB::msgcat::mcpackagelocale isset\fR
.
................................................................................
.
Returns true, if the given locale is loaded for the package.
.TP
\fB::msgcat::mcpackagelocale clear\fR
.
Clear any loaded locales of the package not present in the package preferences.
.PP
.SH Changing package options
.PP
Each package using msgcat has a set of options within \fBmsgcat\fR.
The package options are described in the next sectionPackage options.
Each package option may be set or unset individually using the following ensemble:
.TP
\fB::msgcat::mcpackageconfig get\fR \fIoption\fR
.
................................................................................
The called procedure must return the formatted message which will finally be returned by msgcat::mc.
.PP
A generic unknown handler is used if set to the empty string. This consists in returning the key if no arguments are given. With given arguments, format is used to process the arguments.
.PP
See section \fBcallback invocation\fR below.
The appended arguments are identical to \fB::msgcat::mcunknown\fR.
.RE
.SS Callback invocation
A package may decide to register one or multiple callbacks, as described above.
.PP
Callbacks are invoked, if:
.PP
1. the callback command is set,
.PP
2. the command is not the empty string,
.PP
3. the registering namespace exists.
.PP
If a called routine fails with an error, the \fBbgerror\fR routine for the interpreter is invoked after command completion.
Only exception is the callback \fBunknowncmd\fR, where an error causes the invoking \fBmc\fR-command to fail with that error.
.PP
.SS Examples















































Packages which display a GUI may update their widgets when the global locale changes.
To register to a callback, use:
.CS
namespace eval gui {
    msgcat::mcpackageconfig changecmd updateGUI

    proc updateGui args {

\fB::msgcat::mc \fIsrc-string\fR ?\fIarg arg ...\fR?

Returns a translation of \fIsrc-string\fR according to the
current locale.  If additional arguments past \fIsrc-string\fR
are given, the \fBformat\fR command is used to substitute the
................................................................................
\fB::msgcat::mc\fR is the main function used to localize an
application.  Instead of using an English string directly, an
application can pass the English string through \fB::msgcat::mc\fR and
use the result.  If an application is written for a single language in
this fashion, then it is easy to add support for additional languages
later simply by defining new message catalog entries.

\fB::msgcat::mcn \fInamespace\fR \fIsrc-string\fR ?\fIarg arg ...\fR?
.
Like \fB::msgcat::mc\fR, but with the message namespace specified as first argument.
.PP
.RS
\fBmcn\fR may be used for cases where the package namespace is not the namespace of the caller.
An example is shown within the description of the command \fB::msgcat::mcpackagenamespaceget\fR below.

.TP
\fB::msgcat::mcmax ?\fIsrc-string src-string ...\fR?
.
Given several source strings, \fB::msgcat::mcmax\fR returns the length
of the longest translated string.  This is useful when designing
localized GUIs, which may require that all buttons, for example, be a
fixed width (which will be the width of the widest button).
.TP
.VS "TIP 412"
\fB::msgcat::mcexists\fR ?\fB-exactnamespace\fR? ?\fB-exactlocale\fR? ?\fB-namespace\fR \fInamespace\fR? \fIsrc-string\fR
.
Return true, if there is a translation for the given \fIsrc-string\fR.
.PP
.RS
The search may be limited by the option \fB\-exactnamespace\fR to only check the current namespace and not any parent namespaces.
.PP
It may also be limited by the option \fB\-exactlocale\fR to only check the first prefered locale (e.g. first element returned by \fB::msgcat::mcpreferences\fR if global locale is used).
.PP

An explicit package namespace may be specified by the option \fB-namespace\fR.
The namespace of the caller is used if not explicitly specified.

\fB::msgcat::mcpackagenamespaceget\fR
.
Return the package namespace of the caller.
This command handles all cases described in section \fBOBJECT ORIENTED PROGRAMMING\fR.
.PP
.RS
Example usage is a tooltip package, which saves the caller package namespace to update the translation each time the tooltip is shown:
.CS
proc ::tooltip::tooltip {widget message} {
    ...
    set messagenamespace [uplevel 1 {::msgcat::mcpackagenamespaceget}]

\fB::msgcat::mclocale \fR?\fInewLocale\fR?
.

If \fInewLocale\fR is omitted, the current locale is returned, otherwise the current locale
is set to \fInewLocale\fR.
.PP
.RS
If the new locale is set to \fInewLocale\fR, the corresponding preferences are calculated and set.
For example, if the current locale is en_US_funky, then \fB::msgcat::mcpreferences\fR returns \fB{en_us_funky en_us en {}}\fR.
.PP
The same result may be acheved by \fB::msgcat::mcpreferences\fR {*}[\fB::msgcat::mcutil getpreferences\fR \fInewLocale\fR].
.PP
The current locale is always the first element of the list returned by \fBmcpreferences\fR.
.PP
msgcat stores and compares the locale in a
case-insensitive manner, and returns locales in lowercase.
The initial locale is determined by the locale specified in
the user's environment.  See \fBLOCALE SPECIFICATION\fR
below for a description of the locale string format.

.PP
.VS "TIP 412"
If the locale is set, the preference list of locales is evaluated.
Locales in this list are loaded now, if not jet loaded.
.VE "TIP 412"
.RE

Without arguments, returns an ordered list of the locales preferred by
the user.
The list is ordered from most specific to least preference.
.PP
.VS "TIP 499"
.RS
A set of locale preferences may be given to set the list of locale preferences.
The current locale is also set, which is the first element of the locale preferences list.
.PP
Locale preferences are loaded now, if not jet loaded.

As an example, the user may prefer French or English text. This may be configured by:

\fB::msgcat:mcloadedlocales subcommand\fR ?\fIlocale\fR?
.
This group of commands manage the list of loaded locales for packages not setting a package locale.
.PP
.RS
The subcommand \fBget\fR returns the list of currently loaded locales.
................................................................................
Note that this routine is only called if the concerned package did not set a package locale unknown command name.

The calling package clears all its state within the \fBmsgcat\fR package including all settings and translations.

.TP
\fB::msgcat::mcutil getpreferences\fR \fIlocale\fR
.
Return the preferences list of the given locale as described in section \fBLOCALE SPECIFICATION\fR.
An example is the composition of a preference list for the bilingual region "Biel/Bienne" as a concatenation of swiss german and swiss french:
.CS
% concat [lrange [msgcat::mcutil getpreferences fr_CH] 0 end-1] [msgcat::mcutil getpreferences de_CH]

The system locale is returned as described by the section \fBLOCALE SPECIFICATION\fR.
.VE "TIP 499"
.PP
.SH "LOCALE SPECIFICATION"
.PP
The locale is specified to \fBmsgcat\fR by a locale string
passed to \fB::msgcat::mclocale\fR.
The locale string consists of
a language code, an optional country code, and an optional

.SH "PACKAGE PRIVATE LOCALE"
.PP
A package using \fBmsgcat\fR may choose to use its own package private
locale and its own set of loaded locales, independent to the global
locale set by \fB::msgcat::mclocale\fR.
.PP
This allows a package to change its locale without causing any locales load or removal in other packages and not to invoke the global locale change callback (see below).
.PP
................................................................................
This command may cause the load of locales.
.RE
.TP
\fB::msgcat::mcpackagelocale get\fR
.
Return the package private locale or the global locale, if no package private locale is set.
.TP
\fB::msgcat::mcpackagelocale preferences\fR ?\fIlocale preference\fR? ...
.
With no parameters, return the package private preferences or the global preferences,
if no package private locale is set.
The package locale state (set or not) is not changed (in contrast to the command \fB::msgcat::mcpackagelocale set\fR).
.PP
.RS
.VS "TIP 499"
If a set of locale preferences is given, it is set as package locale preference list.
The package locale is set to the first element of the preference list.
A package locale is activated, if it was not set so far.
.PP
Locale preferences are loaded now for the package, if not jet loaded.
.VE "TIP 499"
.RE

.TP
\fB::msgcat::mcpackagelocale loaded\fR
.
Return the list of locales loaded for this package.
.TP
\fB::msgcat::mcpackagelocale isset\fR

Returns true, if the given locale is loaded for the package.
.TP
\fB::msgcat::mcpackagelocale clear\fR
.
Clear any loaded locales of the package not present in the package preferences.
.PP
.SH "CHANGING PACKAGE OPTIONS"
.PP
Each package using msgcat has a set of options within \fBmsgcat\fR.
The package options are described in the next sectionPackage options.
Each package option may be set or unset individually using the following ensemble:
.TP
\fB::msgcat::mcpackageconfig get\fR \fIoption\fR
.
................................................................................
The called procedure must return the formatted message which will finally be returned by msgcat::mc.
.PP
A generic unknown handler is used if set to the empty string. This consists in returning the key if no arguments are given. With given arguments, format is used to process the arguments.
.PP
See section \fBcallback invocation\fR below.
The appended arguments are identical to \fB::msgcat::mcunknown\fR.
.RE
.SH "Callback invocation"
A package may decide to register one or multiple callbacks, as described above.
.PP
Callbacks are invoked, if:
.PP
1. the callback command is set,
.PP
2. the command is not the empty string,
.PP
3. the registering namespace exists.
.PP
If a called routine fails with an error, the \fBbgerror\fR routine for the interpreter is invoked after command completion.
Only exception is the callback \fBunknowncmd\fR, where an error causes the invoking \fBmc\fR-command to fail with that error.

 *	and < TCL_INDEX_AFTER (INT_MAX).
 *      The largest string supported in Tcl 8 has bytelength INT_MAX.
 *      This means the largest supported character length is also INT_MAX,
 *      and the index of the last character in a string of length INT_MAX
 *      is INT_MAX-1.
 *
 *      Any absolute index value parsed outside that range is encoded
 *      using the before and after values passed in by the
 *      caller as the encoding to use for indices that are either
 *      less than or greater than the usable index range. TCL_INDEX_AFTER
 *      is available as a good choice for most callers to use for
 *      after. Likewise, the value TCL_INDEX_BEFORE is good for
 *      most callers to use for before.  Other values are possible
 *      when the caller knows it is helpful in producing its own behavior
 *      for indices before and after the indexed item.
 *
 *      A token can also be parsed as an end-relative index expression.
 *      All end-relative expressions that indicate an index larger
 *      than end (end+2, end--5) point beyond the end of the indexed
 *      collection, and can be encoded as after.  The end-relative
 *      expressions that indicate an index less than or equal to end
 *      are encoded relative to the value TCL_INDEX_END (-2).  The
 *      index "end" is encoded as -2, down to the index "end-0x7ffffffe"
 *      which is encoded as INT_MIN. Since the largest index into a
 *      string possible in Tcl 8 is 0x7ffffffe, the interpretation of
 *      "end-0x7ffffffe" for that largest string would be 0.  Thus,
 *      if the tokens "end-0x7fffffff" or "end+-0x80000000" are parsed,
 *      they can be encoded with the before value.
 *
 *      These details will require re-examination whenever string and
 *      list length limits are increased, but that will likely also
 *      mean a revised routine capable of returning Tcl_WideInt values.
 *
 * Returns:
 *      TCL_OK if parsing succeeded, and TCL_ERROR if it failed.
 *
 * Side effects:
 *      When TCL_OK is returned, the encoded index value is written
 *      to *indexPtr.

# Tcl package index file, version 1.0
# This file is generated by the "pkg_mkIndex" command
# and sourced either when an application starts up or
# by a "package unknown" script.  It invokes the
# "package ifneeded" command to set up package-related
# information so that packages will be loaded automatically
# in response to "package require" commands.  When this
# script is sourced, the variable $dir must contain the
# full path name of this file's directory.
