Expect to add support for word template replacement text and tables

[ai-emmasun]

Set the text variable and table template to be replaced in the word template, and generate a new document by calling the API to replace the template.

To replace the template function also has a good library, hope to be able to merge to come in, the address is https://github.com/legion-zver/go-docx-templates

This is a code change to support not just loading templates from files but also sending template from calling code which is a bit more "cloud" friendly. My fork includes similar changes for images.

package godocx

import (
	_ "embed"
	"os"
	"path/filepath"

	"godocx/docx"
	"godocx/packager"
)

//go:embed templates/default.docx
var defaultDocx []byte

// NewDocument creates a new document from the default template.
func NewDocument() (*docx.RootDoc, error) {
	return InitialDocument(defaultDocx)
}

// OpenDocument opens a document from the given file name.
func OpenDocument(fileName string) (rd *docx.RootDoc, err error) {
	var docxContent []byte
	if docxContent, err = os.ReadFile(filepath.Clean(fileName)); err != nil {
		return
	}
	return InitialDocument(docxContent)
}

// InitialDocument starts a document using the document template given
func InitialDocument(docTemplate []byte) (*docx.RootDoc, error) {
	return packager.Unpack(docTemplate)
}

Regards.
