.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 {
................................................................................
}

.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.
.PP
.VS tip490
Object oriented programming is supported by the use of a package namespace.

.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
.VS "TIP 490"
.TP
\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.
.RE
.PP
.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
.VE "TIP 412"
.VS "TIP 490"
An explicit package namespace may be specified by the option \fB-namespace\fR.
The namespace of the caller is used if not explicitly specified.
.RE
.PP
.VE "TIP 490"
.VS "TIP 490"
.TP
\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}]
    ...
    bind $widget  [list ::tooltip::show $widget $messagenamespace $message]
}

proc ::tooltip::show {widget messagenamespace message} {
    ...
    set message [::msgcat::mcn $messagenamespace $message]
    ...
}

\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
.TP
\fB::msgcat::mcpreferences\fR ?\fIlocale preference\fR? ...
.
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.
.PP
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.

\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

.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.

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.
