I try to append new text to an existing docx file like this:
readFile, err := os.Open(filename)
if err != nil {
// ...
}
fileinfo, err := readFile.Stat()
if err != nil {
//...
}
size := fileinfo.Size()
oldDoc, err := docx.Parse(readFile, size)
if err != nil {
//...
}
doc := docx.LoadBodyItems(oldDoc.Document.Body.Items, []docx.Media{})
p := doc.AddParagraph()
p.AddText(text).Size("10")
if err != nil {
//...
}
_, err = doc.WriteTo(readFile)
if err != nil {
//...
}
err = readFile.Close()
if err != nil {
//...
}but it just adds new content and erases the old file...
It also seems to ignore '\n' in the text - no new lines are made, how do I insert a new line?
请问现在有可以更换A4为A3的调用吗，以及是否可以添加分页符？
A good open source library cannot go without a good documentation!
Suggest to add in documentation for different use cases and examples.
A good starting point could be based on the existing features:
Maybe it can also be linked back to Microsoft OpenXML's documentation for easier references.
Easier way to get started is by directly writing into the repository's README file but it could get cluttered real quick.
Perhaps having a Nextra documentation site would be helpful.

Is there any possible way to set page margins (w:pgMar)?
go-docx的表格设计， 可以支持表格中的部分表格合并吗，就是类似单元格合并的功能
Hello! I'll try my best to make this issue the last one, so I won't litter issues with my questions that much. Thanks for the help in advance!!!
code:
readFile, err := os.Open(filename)
if err != nil {
slog.Error("error while oppening docx file", "unit_guid", devInfo.UnitGuid, "err", err)
}
fileinfo, err := readFile.Stat()
if err != nil {
slog.Error("error while reading docx file stat file", "unit_guid", devInfo.UnitGuid, "err", err)
}
size := fileinfo.Size()
oldDoc, err := docx.Parse(readFile, size)
if err != nil {
slog.Error("error while parsing docx file", "unit_guid", devInfo.UnitGuid, "err", err)
}
newDoc := docx.NewA4()
p := newDoc.AddParagraph()
p.AddText(text).Size("10")
// ADD OLD FILE CONTENT HERE
newDoc.AppendFile(oldDoc)
if err != nil {
slog.Error("error while creating file", "unit_guid", devInfo.UnitGuid, "err", err)
}
_, err = newDoc.WriteTo(readFile)
if err != nil {
slog.Error("error while writing file", "unit_guid", devInfo.UnitGuid, "err", err)
}
err = readFile.Close()
if err != nil {
slog.Error("error while saving file", "unit_guid", devInfo.UnitGuid, "err", err)
}this whole block of code is executed about 3-4 times, and should add one line to the file at a time
however, after the program exits, the created file has only one out of 3-4 lines it should
I tried literally everything at this point, but still cant get it to work...
Hi, thank you for writing up this library.
Currently, I am facing issue trying to Parse an existing docx file which consists of table with decimal point width as follows:
...
<w:tblW w:w="11116.8" w:type="dxa" />
...doc, err := docx.Parse(readFile, size)
if err != nil {
panic(err)
}And got error output:
strconv.ParseInt: parsing "11116.8": invalid syntaxSuspect is due to this line
https://github.com/fumiama/go-docx/blob/master/structtable.go#L280
I am no expert in working with docx file. Should the library supports decimal points value by using strconv.ParseFloat instead? This might also apply to other components, not just table width.
Thank you!
如何读写修改docx文件并且保存呢 WriteTo 方法并不能保存修改
你好，看了下代码，没有找到设置页面方向 portrait、landscape 相关的代码。
请问可以设置页面方向为横向或者考虑支持吗？
<w:strike>子元素会被跳过
可以在RunProperties加一个Strike成员
并在structrun.go:300加一个case "strike"

I have a requirement to merge certain rows in a table. Do you have any plans to support this feature in the future?
I'm not sure of what's happening here. I have a perfectly functioning .docx as input file. But after parse it (didn't mody a thing) and write it as new file.. the output file gets corrupted)
func OpenDocx(path string) *docx.Docx {
readFile, err := os.Open(path)
util.Panic(err)
fileInfo, err := readFile.Stat()
util.Panic(err)
size := fileInfo.Size()
doc, err := docx.Parse(readFile, size)
util.Panic(err)
return doc
}
func WriteDocx(doc *docx.Docx, path string) {
f, err := os.Create(path)
util.Panic(err)
_, err = doc.WriteTo(f)
util.Panic(err)
err = f.Close()
util.Panic(err)
}and somwhere in my main.go
...
...
doc := docxLib.OpenDocx(inputFile)
docxLib.WriteDocx(doc, "copy.docx")
...
...when I try to open copy.docx in Word, I cannot because of corrupted file.
