.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.
.VE tip490
.PP
.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).

.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).
.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.

\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}]

.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.
.RS

\fB::msgcat::mcpreferences\fR
\fB::msgcat::mcpreferences\fR ?\fIlocale preference\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
Without arguments, returns an ordered list of the locales preferred by
the user.

A set of locale preferences may be given to set the list of locale preferences.

Return the preferences list of the given locale as described in section \fBLOCALE SPECIFICATION\fR.

.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.

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).

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.
