Support for Tracking changes in Paragraph

[devarsh]

Description

I was going through the properties in Paragraph but there is no property in the structure to add <w:ins> and <w:del> child property and then add run to those properties like how MS Word keeps tracks of text changes in the word document.

Below is the code snippet and the generated output and the output generated from Microsoft word.

func main() {
	doc := document.New()
	doc.Settings.X().TrackRevisions = wml.NewCT_OnOff()
	para := doc.AddParagraph()
	doc.AddParagraph()
	run := para.AddRun()
	run.AddText("I am working at")
	AddOldValue(&para, "Yahoo", "00475D3C", 0)
	AddNewValue(&para, "Google", "00475D3C", 1)
	doc.SaveToFile("demo.docx")
}

func AddNewValue(p *document.Paragraph, newVal string, revNum string, id int64) {
	exprops := p.Properties().X()
	pprChange := wml.NewCT_PPrChange()
	exprops.PPrChange = pprChange
	pprChange.AuthorAttr = "Devarsh"
	t := time.Now()
	pprChange.DateAttr = &t
	pprChange.IdAttr = id
	run := p.AddRun()
	run.X().RsidDelAttr = &revNum
	ic := wml.NewEG_RunInnerContent()
	run.X().EG_RunInnerContent = append(run.X().EG_RunInnerContent, ic)
	ic.InstrText = wml.NewCT_Text()
	ic.InstrText.Content = newVal
}

func AddOldValue(p *document.Paragraph, oldVal string, revNum string, id int64) {
	exprops := p.Properties().X()
	pprChange := wml.NewCT_PPrChange()
	exprops.PPrChange = pprChange
	pprChange.AuthorAttr = "Devarsh"
	t := time.Now()
	pprChange.DateAttr = &t
	pprChange.IdAttr = id
	run := p.AddRun()
	run.X().RsidDelAttr = &revNum
	ic := wml.NewEG_RunInnerContent()
	run.X().EG_RunInnerContent = append(run.X().EG_RunInnerContent, ic)
	ic.DelText = wml.NewCT_Text()
	ic.DelText.Content = oldVal
}

Output :

<w:body>
    <w:p>
      <w:pPr>
        <w:pPrChange w:author="Devarsh" w:date="2019-09-06 02:05:53.786744 +0530 IST m=+0.002038602" w:id="1">
          <w:pPr/>
        </w:pPrChange>
      </w:pPr>
      <w:r>
        <w:t>I was working at</w:t>
      </w:r>
      <w:r w:rsidDel="00475D3C">
        <w:delText>Yahoo</w:delText>
      </w:r>
      <w:r w:rsidDel="00475D3C">
        <w:instrText>Google</w:instrText>
      </w:r>
    </w:p>
    <w:p/>
  </w:body>
