Examples

Shows how to use NUMCHARS, NUMWORDS, NUMPAGES and PAGE fields to track the size of our documents.

doc = aw.Document(MY_DIR + "Paragraphs.docx")
builder = aw.DocumentBuilder(doc)

builder.move_to_header_footer(aw.HeaderFooterType.FOOTER_PRIMARY)
builder.paragraph_format.alignment = aw.ParagraphAlignment.CENTER

# Below are three types of fields that we can use to track the size of our documents.
# 1 -  Track the character count with a NUMCHARS field:
field_num_chars = builder.insert_field(aw.fields.FieldType.FIELD_NUM_CHARS, True).as_field_num_chars()
builder.writeln(" characters")

# 2 -  Track the word count with a NUMWORDS field:
field_num_words = builder.insert_field(aw.fields.FieldType.FIELD_NUM_WORDS, True).as_field_num_words()
builder.writeln(" words")

# 3 -  Use both PAGE and NUMPAGES fields to display what page the field is on,
# and the total number of pages in the document:
builder.paragraph_format.alignment = aw.ParagraphAlignment.RIGHT
builder.write("Page ")
field_page = builder.insert_field(aw.fields.FieldType.FIELD_PAGE, True).as_field_page()
builder.write(" of ")
field_num_pages = builder.insert_field(aw.fields.FieldType.FIELD_NUM_PAGES, True).as_field_num_pages()

self.assertEqual(" NUMCHARS ", field_num_chars.get_field_code())
self.assertEqual(" NUMWORDS ", field_num_words.get_field_code())
self.assertEqual(" NUMPAGES ", field_num_pages.get_field_code())
self.assertEqual(" PAGE ", field_page.get_field_code())

# These fields will not maintain accurate values in real time
# while we edit the document programmatically using Aspose.Words, or in Microsoft Word.
# We need to update them every we need to see an up-to-date value.
doc.update_fields()
doc.save(ARTIFACTS_DIR + "Field.field_num.docx")
