Describe the bug
When you modify the word document and save it, the old document.xml must be replaced.
But currently It adds a file with the same name to the word document.

Example
In this case, after calling save function we have two document.xml:
Archive: my_test.docx
Length Date Time Name

  573  02-03-2019 17:16   _rels/.rels
  513  02-03-2019 17:16   docProps/app.xml
  732  02-03-2019 17:16   docProps/core.xml
  531  02-03-2019 17:16   word/_rels/document.xml.rels
  280  02-03-2019 17:16   word/settings.xml
  853  02-03-2019 17:16   word/fontTable.xml
 1480  02-03-2019 17:16   word/document.xml
 2585  02-03-2019 17:16   word/styles.xml
 1118  02-03-2019 17:16   [Content_Types].xml
 1602  07-03-2019 23:14   word/document.xml

10267                     10 files

Expected behavior
Remove the old document.xml and replace it with the new one.

Additional context
This may be due to the zip library.

Many of the recent Pull Requests have experienced issues with build failures due to the old GCC 5 on Travis CI (this might be a bug in the travis config as the intended version seems to be 6). Many of the modern C++ features (11 and above) don't appear to be fully supported.

I couldn't find anything explicitly stating that this library should support C++98 compilers. Could you clarify what is the minimum version we should target, and then update the cmake config to reflect this.

Personally I don't see any reason to keep support for C++98, as this is a new library there is no legacy code that depends on it compiling in C++98. Additionally many features we know and love (smart pointers, lambdas, auto, move semantics, etc.)

i am a newer in c++ could you give me a example about how to create a docx example

For example I have a task. Make a 20x3 table with number sequences. According to the examples, I can create it manually, read it with DuckX, and display it in the console for example. But can I create it automatically and fill it in automatically?

I would be interested in the ability to work with images in a Word .docx file.

Examples:

• Insert a new PNG or JPG (or other) image in the document
• Access image data in a document as an array of bytes
• Methods for identifying the image format or file type

This feature would be useful when generating reports from C++ software, where charts, maps or other kinds of figures are required.

To do this currently, it's necessary to jump through a lot of hoops involving writing temporary files in an intermediate format (e.g. HTML) and then invoking external executables to handle the conversion to docx. This is a massive pain. It would be much better to be able to do this entirely within C++ code.

DuckX is using zip library that only supports appending or writing new files. (unable to update a file inplace!)
So currently Save function works as follows:

• make a new file
• write any new files
• copy the old files
• delete old docx
• rename new file to old file

And this process has a terrible performance on large files!

I test sample1.cpp, it works fine.

While I change the code by giving it a Chinese docx file, the output can not be read.
Seems to be concerned with character encoding.

Help!

Describe the bug
I followed the steps of installing, but when I try to build my project I got an error("cannot open source file "duckx.hpp" ")
I'm working in visual studio 2017
Can you help me ?
Or can you be more specified with instructions of installing ? maybe I missed a step

Thank you :) !

Describe the bug
Whenever .open is called on a Document object that has a directory that is not a word document the application crashes.

To Reproduce
Steps to reproduce the behavior:
create a project and add this code:
duckx::Document doc("test.docx");
doc.open();

make sure test.docx does not exist

run the code

Expected behavior
A new docx file named test should be crated, but instead the application crashes

Additional context
Add any other context about the problem here.

Paragraph::has_next returns true if the current paragraph exists in the document, even if there is no next paragraph. next() then returns an empty paragraph which does not exist.

Since that last paragraph is empty, this issue is unnoticeable when reading a document. The problem occurs when the user tries inserting a paragraph after the last paragraph:

Paragraph last = doc.paragraphs();
while(last.has_next()) last = last.next();
last.insert_paragraph_after("This should appear after the last paragraph!");

Since last is actually a non-existing paragraph referring to an pugi::xml_node without a rode, the last paragraph is not written to the file.

I intend to fix this issue myself. I also want to add methods append_paragraph and append_run to Document. This would allow generating a long document without using a while loop to obtain the last paragraph as in the example above, and then working on a new Paragraph object for every new paragraph; instead, one would only use the Document object the entire time.

When creating an instance of Document without any file path the code executes with no errors.
However, when you create it with a file path it returns an error ("1 unresolved externals")

It would be useful to have the ability to access & modify document properties.

This would allow creating a template docx file, with fields set up to display custom document properties. Using DuckX, the property values could be populated with output data from C++ software. When loaded into MS Word, the final docx file would display the completed report, and user would still have the ability to edit.

To work around the lack of document property support at the moment, I am experimenting with searching all paragraphs for a particular string (e.g. [REPORTBODY]) and replacing with the corresponding value.

For me I changed the source code in Visual Studio, so that I am able to work with documents with headers and footers. Where can I put the changed the code, so that somebody can review and test it.
One question Í have: is there a way to duplicate a document within Duckx, so that I could produce the basis for serial letters, because I want to get rid of the MS macros in word. There are to much restrictions.

Function bool duckx::Run::set_text(const char *text) writes text into document.xml with no issues for English characters.
When I try to write Russian letters (wide char) it writes with no issues but the MS Word can not open the docx file showing an error.

What I tried (stages):

1. Create docx with one Russian letter (i.e Ж)
2. Replace Russian letter with English one (i.e J) using set_text function.
3. Save document - DOCX OPENS WITH NO ERRORS
4. Replace English Letter with Russian (J -> Ж)
5. Save document - DOCX OPENS WITH AN ERROR
6. Replace Russian Letter with the English one (Ж -> J)
7. Save document - NO ERRORS

I compared original file (stage 1 - manually created file with Russian letter) and the one with an English letter (stage 7 or 3). The only file that was changed is document.xml.

Stage 1 - document.xml has UTF-8 encoding and header <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
Stage 2-7 - document.xml now has ANSI encoding and NO header from stage 1. The letter writes correctly inside <w:t>Ж</w:t>. But due to ANSI encoding and removed header from original file it can not be opened if contain wide characters. No issues for ordinary characters though.

Is there's something I am missing in library configuration or is it a bug then?

Does DuckX support to create new docx files?
The README file says that it supports to create docx files, but I can only get damaged files after calling the Save function.
Maybe I made some mistakes. Could you give me a sample of create new docx files? Thanks a lot.

Describe the bug
When a word document is opened, reading the file will fail

I found duckx support font image setting. but how to set text font?

I would like to use this library for my android project can you tell me how can i compile it for android.

The project just provide api, but I don't know how to create a 3*3 table. I would be apprecicate if someone can provide me a demo.

I believe this could be due to a an error on line 23 of CMakeLists.txt

Does DuckX support to insert image into docx file?
The website says that it supports Adding Images to Word DOCX Files, but I cannot find any hints in the samples.
Could you clarify it? Thanks a lot.

Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:
p.add_run("A ");
p.add_run("run");
p.add_run(" test");

Expected behavior
"A run test" is expected; "Aruntest" is obtained. The leading and trailing spaces are there in the XML, but they are not preserved unless xml:space="preserve" is added to the "w:t" tag.

I plan to fix this myself; I'm opening an issue as requested in Contributing.md.

Describe the bug
In a word document, one line of text is mixed in Chinese and English, but the read text is multiple lines

Paragraphs inside tables are not reported by the library.

First of all thanks so much for creating this library!
Very clean and easy to use interface with few dependencies - great!
I tried libopc and while it seems to be very comprehensive, it has a ton of dependencies which makes it rather hard to add to a real app.

I'm about to start a new project which requires parsing docx (among others).
I thought there would be several libraries for reading docx files with C++ but had to find out there are actually not many.

The documents I need to parse typically contain tables and while using the DuckX sample code I'm ending up with almost no output. Do you think it's possible to add support for tables in the near future?

Thanks and keep up the great work!

I'm trying to add few paragraph at the end of my file but it is impossible. I tried

While(p.has_next())
p = p.next()

but it doesn't write anything.

I tried other things that a i don't remember. Do you have the issue ?

Thanks
