after the if { ... }. I.e., it must be placed after the code
for creating the English translator at the beginning, and before the
else { ... } part that creates the translator for the
default language (English again).

twice (i.e. in the \c \#ifndef and \c \#define preprocessor commands at
the beginning of the file).
idLanguage() change "english" into the
name of your language (use lower case characters only). Depending
on the language you may also wish to change the member functions
latexLanguageSupportCommand(), idLanguageCharset() and others
(you will recognize them when you start the work).
OUTPUT_LANGUAGE = your_language_name
in the config file to generate output in your language.
translator_xx.h to me so I can add it to doxygen.
Send also your name and e-mail address to be included in the
\c maintainers.txt list.
trFile(true, false) is called. This is the
mostly used case at the time of introducing the new method -- see
above. While this may look too complicated, the technique allows
the developers of the core sources to change the Translator
interface, while the users may not even notice the change. Of
course, when the new \c trFile() is used with different arguments,
the English result is returned and it will be noticed by non English
users. Here the maintainer of the language translator should
implement at least that one particular method.
What says the base class of a language translator?
If the language translator class inherits from any adapter class the
maintenance is needed. In such case, the language translator is not
considered up-to-date. On the other hand, if the language
translator derives directly from the abstract class \c Translator, the
language translator is up-to-date.
The translator adapter classes are chained so that the older
translator adapter class uses the one-step-newer translator adapter
as the base class. The newer adapter does less \e adapting work
than the older one. The oldest adapter class derives (indirectly)
from all of the adapter classes. The name of the adapter class is
chosen so that its suffix is derived from the previous official
version of doxygen that did not need the adapter. This way, one can
say approximately, when the language translator class was last
updated -- see details below.
The newest translator adapter derives from the abstract \c
TranslatorAdapterBase class that derives directly from the abstract
\c Translator class. It adds only the private English-translator
member for easy implementation of the default translation inside the
adapter classes, and it also enforces implementation of one method
for noticing the user that the language translation is not up-to-date
(because of that some sentences in the generated files may appear in
English).
Once the oldest adapter class is not used by any of the language
translators, it can be removed from the doxygen project. The
maintainers should try to reach the state with the minimal number of
translator adapter classes.
To simplify the maintenance of the language translator classes
for the supported languages, the \c translator.py Python
script was developed (located in \c doxygen/doc directory).
It extracts the important information about obsolete and
new methods from the source files for each of the languages.
The information is stored in the translator report ASCII file
(translator_report.txt). \htmlonly If you compiled this documentation
from sources and if you have also doxygen sources available the
link doxygen/doc/translator_report.txt should be valid.\endhtmlonly
Looking at the base class of the language translator, the script
guesses also the status of the translator -- see the last column of
the table with languages above. The \c translator.py is called
automatically when the doxygen documentation is generated. You can
also run the script manualy whenever you feel that it can help you.
Of course, you are not forced to use the results of the script. You
can find the same information by looking at the adapter class and
its base classes.
How should I update my language translator? Firstly, you
should be the language maintainer, or you should let him/her know
about the changes. The following text was written for the language
maintainers as the primary audience.
There are several approaches to be taken when updating your
language. If you are not extremely busy, you should always chose
the most radical one. When the update takes much more time than you
expected, you can always decide use some suitable translator adapter to
finish the changes later and still make your translator working.
The most radical way of updating the language translator is
to make your translator class derive directly
from the abstract class \c Translator and provide translations for the
methods that are required to be implemented -- the compiler will
tell you if you forgot to implement some of them. If you are in
doubt, have a look at the \c TranslatorEnglish class to recognize the
purpose of the implemented method. Looking at the previously used
adapter class may help you sometimes, but it can also be misleading
because the adapter classes do implement also the obsolete methods
(see the previous \c trFiles() example).
In other words, the up-to-date language translators do not need the
\c TranslatorAdapter_x_y_z classes at all, and you do not need to
implement anything else than the methods required by the Translator
class (i.e. the pure virtual methods of the \c Translator -- they
end with =0;).
If everything compiles fine, try to run \c translator.py, and have a
look at the translator report (ASCII file) at the \c doxygen/doc
directory. Even if your translator is marked as up-to-date, there
still may be some remarks related to your souce code. Namely, the
obsolete methods--that are not used at all--may be listed in the
section for your language. Simply, remove their code (and run the \c
translator.py again). Also, you will be informed when you forgot to
change the base class of your translator class to some newer adapter
class or directly to the Translator class.
If you do not have time to finish all the updates you should
still start with the most radical approach as described
above. You can always change the base class to the translator
adapter class that implements all of the not-yet-implemented methods.
If you prefer to update your translator gradually, have a look
at \c TranslatorEnglish (the \c translator_en.h file). Inside, you
will find the comments like new since 1.2.4 that separate
always a number of methods that were implemented in the stated
version. Do implement the group of methods that are placed below the
comment that uses the same version numbers as your translator adapter
class. (For example, your translator class have to use the \c
TranslatorAdapter_1_2_4, if it does not implement the methods below
the comment new since 1.2.4. When you implement them,
your class should use newer translator adapter.
Run the \c translator.py script occasionaly and give it your \c xx
identification (from \c translator_xx.h) to create the translator
report shorter (also produced faster) -- it will contain only the
information related to your translator. Once you reach the state when
the base class should be changed to some newer adapter, you will see
the note in the translator report.
Warning: Don't forget to compile Doxygen to discover, whether it is
compilable. The \c translator.py does not check if everything is
correct with respect to the compiler. Because of that, it may lie
sometimes about the necessary base class.
The most obsolete language translators would lead to
implementation of too complicated adapters. Because of that, doxygen
developers may decide to derive such translators from the \c
TranslatorEnglish class, which is by definition always up-to-date.
When doing so, all the missing methods will be replaced by the
English translation. This means that not-implemented methods will
always return the English result. Such translators are marked using
word \c obsolete. You should read it really obsolete. No
guess about the last update can be done.
Often, it is possible to construct better result from the obsolete
methods. Because of that, the translator adapter classes should be
used if possible. On the other hand, implementation of adapters for
really obsolete translators brings too much maintenance and
run-time overhead.
