| | 1 | This is the README file for the internationalization sample for wxWidgets. |
| | 2 | |
| | 3 | Q. What does this stupid program do? |
| | 4 | A. It demonstrates how to translate all program messages to a foreign language. |
| | 5 | In any program using wxWidgets there is going to be 3 kinds of messages: the |
| | 6 | messages from the program itself, the messages from the wxWidgets library and |
| | 7 | the messages from the system (e.g. system error messages). This program |
| | 8 | translates the first 2 kinds of messages but the system messages will be only |
| | 9 | translated if your system supports it. |
| | 10 | |
| | 11 | Brief usage summary: "Test|File" tries to open a non existing file (provoking |
| | 12 | system error message), "Test|Play" shows a message box asking for a number. |
| | 13 | Hint: try some special values like 9 and 17. |
| | 14 | |
| | 15 | Q. Why the error message when I try to open a non existing file is only partly |
| | 16 | translated? |
| | 17 | A. Your system doesn't have the translation in the language you use, sorry. |
| | 18 | |
| | 19 | Q. Why the message when I enter '9' is not translated? |
| | 20 | A. This is on purpose: the corresponding string wasn't enclosed in _() macro and |
| | 21 | so didn't get into the message catalog when it was created using xgettext. |
| | 22 | |
| | 23 | Q. Why the message when I enter '17' is only partly translated? |
| | 24 | A. This will only work under some versions of Linux, don't worry if the second |
| | 25 | half of the sentence is not translated. |
| | 26 | |
| | 27 | Q. I don't speak french, what about translations to <language>? |
| | 28 | A. Please write them - see the next question. French is chosen by default |
| | 29 | because it's the only translation which is currently available. To test |
| | 30 | translations to the other languages please run the sample with 2 command line |
| | 31 | arguments: the full language name and the name of the directory where the |
| | 32 | message catalogs for this language are (will be taken as 2 first letters of |
| | 33 | the language name if only 1 argument is given). |
| | 34 | |
| | 35 | Q. How to do translations to other language? |
| | 36 | A. First of all, you will need the GNU gettext tools (see the next questions). |
| | 37 | After you've probably installed them, type the following (example is for Unix |
| | 38 | and you should do exactly the same under Windows). |
| | 39 | |
| | 40 | # all translations forgiven language should be in a separate directory. |
| | 41 | # Please use the standard abbreviation for the language names! |
| | 42 | mkdir <language> |
| | 43 | cd <language> |
| | 44 | |
| | 45 | # generate the .po file for the program itself |
| | 46 | # see `xgettext --help' for options, "-C" is important! |
| | 47 | xgettext -C -n -k_ -kwxPLURAL:1,2 -kwxTRANSLATE -o internat.po ../internat.cpp |
| | 48 | |
| | 49 | # .po file for wxWidgets might be generated in the same way. An already |
| | 50 | # generated wxstd.pot as well as translations for some languages can be |
| | 51 | # found in the locale directory. |
| | 52 | cp ../../locale/<language>.po ./wxstd.pot |
| | 53 | - or - |
| | 54 | cp ../../locale/wxstd.pot . |
| | 55 | |
| | 56 | # now edit the files and do translate strings (this isn't done by gettext) |
| | 57 | # you can use another editor if you wish :-) No need to edit wxstd.pot if you |
| | 58 | # already got a translated one. |
| | 59 | vi internat.po wxstd.pot |
| | 60 | |
| | 61 | # create the message catalog files |
| | 62 | msgfmt -o internat.mo internat.po |
| | 63 | msgfmt -o wxstd.mo wxstd.pot |
| | 64 | |
| | 65 | # run the sample to test it |
| | 66 | cd .. |
| | 67 | ./internat <language> |
| | 68 | |
| | 69 | Q. How to do update the translation of 'internat' sample for a language? |
| | 70 | A. First of all, you will need the GNU gettext tools (see the next question). |
| | 71 | After you've probably installed them, type the following (example is for Unix |
| | 72 | and you should do exactly the same under Windows). |
| | 73 | |
| | 74 | # enter the directory of an already-existing translations which needs to be updated |
| | 75 | cd <language> |
| | 76 | |
| | 77 | # the -j flag tells xgettext to merge and not simply overwrite the output file |
| | 78 | xgettext -j -C -n -k_ -kwxPLURAL:1,2 -kwxTRANSLATE -o internat.po ../internat.cpp |
| | 79 | |
| | 80 | # now edit the files and do translate the new strings (this isn't done by gettext) |
| | 81 | vi internat.po |
| | 82 | |
| | 83 | # update the message catalog: |
| | 84 | msgfmt -o internat.mo internat.po |
| | 85 | |
| | 86 | Q. How to get the gettext tools? |
| | 87 | A. For Unix, you should be able to get the source distribution of any GNU mirror |
| | 88 | (see www.gnu.org for a start). gettext() version 0.10 is buggy, try to get at |
| | 89 | least version strictly greater than 0.10. gettext RPMs can be downloaded from |
| | 90 | the standard locations for Linux. For Windows, you can get the precompiled |
| | 91 | binaries from wxWidgets web page. |
| | 92 | |
| | 93 | Q. What's i18n? |
| | 94 | A. Count the number of letters in the word "internationalization". |
| | 95 | |
| | 96 | Q. Where to send comments, |
| | 97 | additional translations, |
| | 98 | flames, |
| | 99 | money? |
