I have a Qt project which uses XML files. Those XML files contain human-readable text and this text should be translated by using the Qt tools (lupdate, lrelease, QtLinguist).
The question is if it is possible to generate entries in .ts file via lupdate without duplicating the strings from the XML files in a source code file by using the QT_TR_NOOP() macro and friends? Or in general, how do you translate strings in non-source files for Qt projects?
We had the same problem : XML files containing human readable strings.
Our solution was to make sure that human readable strings in the XML files were easy to extract (we put them in a LABEL attribute) and we developped a small tool which would parse the XML files, extract the strings, generate a context (by extracting data from the XML file), and then generating a CPP header file containing a list of QT_TR_NOOP().
This file was added to our project file (.pro) that was used by lupdate.
This solution was fine for us but we had to be very careful about two things :
run this tool each time the content of an XML file changed.
make sure the XML files are UTF-8 encoded.
You can translate anything you want at runtime by using tr(), as long as the .qm file has a matching translation/context. It shouldn't make any difference whether lupdate extracted it or not.
I don't know how to make lupdate to extract strings from arbitrary XML, but that doesn't mean you can't use linguist.
.ts files are also XML; it should be easy to make an XSLT that transforms your XML into a .ts file. If you want to target something standard instead of just Qt, lupdate(and linguist) can process also XLIFF files.
you can have multiple .ts files (just call QTranslator::load more than once when setting it up)
If you really want to have it all in one file for the translator, have your XSLT copy the lupdate-generated file into its output.
As long as you use a context name that doesn't duplicate something used in the source code, this shouldn't be any different (from Qt's point of view) from the way many apps load a .qm for each DLL that has GUI.

I am working on a multilingual project with wxWidgets, coding in c++. For now, the texts I was translating were all in the cpp files using gnu gettext. Now, I want to use xml files for specific configuration parameters. Among those are different strings to be displayed in multilingual.
Current solution
I design the xml as follows. I declare the strings to be displayed, and I also declare the respective translated strings in the xml. I can then upload them in my program while reading the xml and look in the resulting container for a string depending on the language. But I think this solution is not as elegant as with using gettext.
Do you have better ideas? Am I able to somehow use gettext with xml files on specific nodes?
I thank you in advance for your help.
I've got a C++ Plug-in project that needs to be translatable. As such I've created a Dictionary class that can be used to access the strings. However, I'm not entirely sure what the best way of storing the strings is. I was thinking of creating an XML file and storing all the strings there with their different locales stored under one variable name, e.g.
<sHello>
<en_GB>Hello</en_GB>
<fr_FR>Bonjour</fr_FR>
...
</sHello>
However, I would prefer not to have to distribute the XML file along with the other distributables. The Plug-in needs to be cross platform so I'm developing the Windows version in Visual Studio and the Mac OS version in XCode. Preferably, the C++ code in my Dictionary class for accessing the XML values would be the same on both platforms, meaning I could just included the XML in the respective projects and not have to worry about maintaining 2 separate code bases.
Is it possible to embed the XML file as a compiled resource in such a way that it doesn't need to be distributed?
What's wrong with distributing the xml file?
If you really don't want to distribute the XML file, you could make a small utility program that converts the xml file to a C++ source file that would look e.g like this:
// autogenerated by <put your fancy name here>
// Don't hand edit this source file
const char xmlfile[] = "<sHello>\
<en_GB>Hello</en_GB>\
<fr_FR>Bonjour</fr_FR>\
...\
</sHello>";
Instead of XML you could use any other suitable format such as json or whatever you think fits best for your needs.
Currently, i am working on a project using WEKA. Being naive and newbie in it, there are many things which i am not familair with. In my last project I used text files as a classification using WEKA. I applied the TextDirectoryLoader convertor to convert a directory containing text files as mentioned on this URL Text categorization with WEKA. Now I want to use the same stretagy for converting a directory containing source code (instead of text). For example, I have a Jedit source file containing Java source code. I am trying to convert it to ARFF file so that i can apply classifiers or other functions present in WEKA on that ARFF file for data mining purposes. I have also tried a test file given on following URL ARFF files from Text Collections. I believe i can use the same file as an example to convert source code files. However, I do not know what attributes should I define in a FastVector? and What format should the data be in (String or numeric). And what other sections should an ARFF file may have?
As in the example the authors have defined following attributes
FastVector atts = new FastVector(2);
atts.addElement(new Attribute("filename", (FastVector) null));
atts.addElement(new Attribute("contents", (FastVector) null));
I have tried to find some examples on Google but no success.
Could anyone here suggests me any solution or alternate to solve the above said problem? (Example code will be highly appreciated).
Or atleast could give me a short example which convertes a source code directory into an ARFF file. (If it is possible).
If not possible what could be the possible reason
Any alternate solution (except WEKA) where I can use the same set of functions on a source code.
It is not clear, what is your goal? Do you want to classify the source code files, or find the files which are contains any bug, or what?
As I imagine, you want to extract features from each source file, and represent it with an instance. Then you can apply any machine learning based algorithm.
Here, you can find a java example, how can you construct an arff file from java:

But, you have to define your task specific features and extract it from each source code files.
I have a folder that contains 300 different files. There are 150 .cft files and 150 .s01 files. Each .cft file has a corresponding .s01 file of the same name. I would like to create a program that can read the files from the folder and place each .cft file and its corresponding .s01 file into an excel document. I would like the .cft file to be on the first worksheet in the document and the .s01 file to be on the second sheet. Then I would like the program to save the file and name it (---------).xls. The (---------) would be the name of the .cft and .s01 file since they are both the same.
So!!! I wrote a program that is able to take the .cft file and the .s01 file, append them and place them in a user defined .xls document. However...I don't want to manually get the names of the 150 files and have to type each one into the program. I also don't want the files to be placed on the same worksheet.
So!!!! I don't want to waste time trying to code something impossible, so before I spend anymore time on this I have a few questions:
Is it possible to read all of the files in a folder and match files of the same name but with different types?
If this is possible, is it then possible to place the corresponding .cft file and .s01 file in the same excel document but on different worksheets?
Then, is it possible to create and save this worksheet as (---------).xls, (-------) being the name of the matching .cft and .s01 file?
So basically...I want to write this code because I am lazy and I don't want to do anything manually ><;;; lol
Example:
The main folder contains 8 files:
dog.cft dog.s01 cat.cft cat.s01 tree.cft tree.s01 bird.cft bird.s01
The program reads all of the files in the folder and recognizes that dog.cft and dog.s01 go together.
The program then creates an excel document and on worksheet 1 places dog.cft and on worksheet 2 places dog.s01.
The program then saves the excel document as dog.xls
Then the program loops through the main folder repeating this process for each of the .cft and .s01 pairs until all 150 pairs have been separated and saved in their own excel document.
I don't know if I'm dreaming a little too big with this but any advice is much appreciated!
personally I would do this with a macro in excel rather than in c++ because doing excel related functions is much easier that way. All of the requirements are possible using VBA within excel.
Yes, it's possible.
For the listing of files in a folder, you can use the Windows API functions FindFirstFile and FindNextFile. When you finish iterating the folder, you'll need to call FindClose.
For creating the Excel spreadsheet and working with the workbook's sheets, you can use COM automation. Here's a link to an article on doing so from C++ (MFC); the article explains where to find one that isn't MFC based.
If you get started and have specific questions about either of the tasks, please post them as separate questions. This should have been two individual questions, in fact - one about iterating the content of a folder and a different one about working with Excel files from C++.
I am writing a Word add-in which is supposed to store some own XML data per document using Word object model and its CustomXMLPart. The problem I am now facing is the lack of IStream-like functionality for reading/writing XML to/from a CustomXMLPart. It only provides BSTR interface and I am puzzled how to handle UTF-8 XMLs with BSTRs. To my understanding an UTF-8 XML file should really never have to undergo this sort of Unicode conversion. I am not sure what to expect as a result here.
Is there another way of using Word automation interfaces to store arbitrary custom information inside a DOCX file?
The "package" is an OPC document (Open Packaging Convention), which is basically a structured zip folder with a different extension (e.g. .pptx, .docx, .xps, etc.). You can get that file in stream and manipulate it any which way you like - but not artibitrarily. It will not be recognized as valid docx if you put things in the wrong places (not just xml elements, but also files in the folders inside the zip file). But if you're just talking "artibitrary" meaning CustomXMLPart, then that's okay.
This is a good kicker page to learn more about the Open XML SDK and if you're up to it, which allows for somewhat easier access to the file formats than using (.NET) System.IO.Packaging or a third-party zip library. To go deeper, grab the eBook (free) Open XML Explained.
With the Open XML SDK (again, this can all be done without the SDK) in .NET, this is what you'll want to do: How to: Insert Custom XML to an Office Open XML Package by Using the Open XML API.
