Boost.Regex provides extensive support for run-time localization, the localization
model used can be split into two parts: front-end and back-end.
< / p >
< p >
Front-end localization deals with everything which the user sees - error
messages, and the regular expression syntax itself. For example a French
application could change [[:word:]] to [[:mot:]] and \w to \m. Modifying
the front end locale requires active support from the developer, by providing
the library with a message catalogue to load, containing the localized strings.
Front-end locale is affected by the LC_MESSAGES category only.
< / p >
< p >
Back-end localization deals with everything that occurs after the expression
has been parsed - in other words everything that the user does not see or
interact with directly. It deals with case conversion, collation, and character
class membership. The back-end locale does not require any intervention from
the developer - the library will acquire all the information it requires
for the current locale from the underlying operating system / run time library.
This means that if the program user does not interact with regular expressions
directly - for example if the expressions are embedded in your C++ code -
then no explicit localization is required, as the library will take care
of everything for you. For example embedding the expression [[:word:]]+ in
your code will always match a whole word, if the program is run on a machine
with, for example, a Greek locale, then it will still match a whole word,
but in Greek characters rather than Latin ones. The back-end locale is affected
by the LC_TYPE and LC_COLLATE categories.

There are three separate localization mechanisms supported by Boost.Regex:

This is the default model when the library is compiled under Win32, and is
2007-12-14 10:11:21 +00:00
encapsulated by the traits class < code class = "computeroutput" > < span class = "identifier" > w32_regex_traits< / span > < / code > .
2008-12-23 11:46:00 +00:00

2007-06-08 09:23:23 +00:00
LCID, by default this is the users default setting as returned by GetUserDefaultLCID,
2007-12-14 10:11:21 +00:00
but you can call imbue on the < code class = "computeroutput" > < span class = "identifier" > basic_regex< / span > < / code >
2007-06-08 09:23:23 +00:00
object to set it's locale to some other LCID if you wish. All the settings
used by Boost.Regex are acquired directly from the operating system bypassing
the C run time library. Front-end localization requires a resource dll, containing
a string table with the user-defined strings. The traits class exports the
function:
< / p >
2007-12-14 10:11:21 +00:00

2007-06-08 09:23:23 +00:00

which needs to be called with a string identifying the name of the resource
dll, before your code compiles any regular expressions (but not necessarily
2007-12-14 10:11:21 +00:00
before you construct any < code class = "computeroutput" > < span class = "identifier" > basic_regex< / span > < / code >

This model has been deprecated in favor of the C++ locale for all non-Windows

2007-06-08 09:23:23 +00:00
can force this model to take effect by defining the pre-processor symbol
BOOST_REGEX_USE_C_LOCALE. When this model is in effect there is a single
2007-12-14 10:11:21 +00:00
global locale, as set by < code class = "computeroutput" > < span class = "identifier" > setlocale< / span > < / code > .
2007-06-08 09:23:23 +00:00
All settings are acquired from your run time library, consequently Unicode
support is dependent upon your run time library implementation.

Finally note that if you build the library with a non-default localization
model, then the appropriate pre-processor symbol (BOOST_REGEX_USE_C_LOCALE
or BOOST_REGEX_USE_CPP_LOCALE) must be defined both when you build the support
2007-12-14 10:11:21 +00:00
library, and when you include < code class = "computeroutput" > < span class = "special" > < < / span > < span class = "identifier" > boost< / span > < span class = "special" > /< / span > < span class = "identifier" > regex< / span > < span class = "special" > .< / span > < span class = "identifier" > hpp< / span > < span class = "special" > > < / span > < / code >

in your code. The best way to ensure this is to add the #define to < code class = "computeroutput" > < span class = "special" > < < / span > < span class = "identifier" > boost< / span > < span class = "special" > /< / span > < span class = "identifier" > regex< / span > < span class = "special" > /< / span > < span class = "identifier" > user< / span > < span class = "special" > .< / span > < span class = "identifier" > hpp< / span > < span class = "special" > > < / span > < / code > .

In order to localize the front end of the library, you need to provide the
library with the appropriate message strings contained either in a resource
dll's string table (Win32 model), or a POSIX message catalogue (C++ models).
In the latter case the messages must appear in message set zero of the catalogue.
The messages and their id's are as follows:

Finally, custom collating element names are loaded starting from message
id 400, and terminating when the first load thereafter fails. Each message
looks something like: "tagname string" where tagname is the name
used inside [[.tagname.]] and string is the actual text of the collating
element. Note that the value of collating element [[.zero.]] is used for
the conversion of strings to numbers - if you replace this with another value
then that will be used for string parsing - for example use the Unicode character
0x0660 for [[.zero.]] if you want to use Unicode Arabic-Indic digits in your
regular expressions in place of Latin digits.
< / p >
< p >
Note that the POSIX defined names for character classes and collating elements
are always available - even if custom names are defined, in contrast, custom
error messages, and custom syntax messages replace the default ones.
