Module: Uniword::Wordprocessingml::DocumentStyling

Included in:
DocumentRoot
Defined in:
lib/uniword/wordprocessingml/document_styling.rb

Overview

Theme and style application for DocumentRoot — Word's Design/Layout/Styles surfaces as document-level API.

Extracted from DocumentRoot to keep the document model focused: bundled and file-based theme application, stylesets, font and color schemes, font replacement, page setup, and style management (rename/remove).

#auto_transition_theme ⇒ Hash?

Auto-transition from MS theme to Uniword equivalent

Detects the MS theme in the document's embedded theme and replaces it with the corresponding Uniword theme (font-substituted, renamed).

puts "Transitioned from " \
     "#{result[:ms_name]} to #{result[:uniword_slug]}"

Returns:

  • (Hash, nil) —

    { uniword_slug:, ms_name: } or nil if no match

#remove_style(style_id) ⇒ Style?

Remove one style from the document's style definitions

Default styles (w:default="1") are never removed.

Parameters:

  • style_id (String) —

    Style id (w:styleId)

Returns:

#rename_style(identifier, new_name) ⇒ Style?

Rename a style's display name (w:name) — Word's style rename. References (pStyle/rStyle/tblStyle) target the styleId, so they keep working unchanged.

Parameters:

  • identifier (String) —

    Style id (w:styleId) or current display name (w:name)

  • new_name (String) —

    New display name

Returns:

#replace_font(from:, to:) ⇒ Integer

Replace one font family with another across the document

Mirrors Word's Home → Replace → Replace Fonts: rewrites rFonts references in styles and defaults, body content, headers, footers, notes, comments, and numbering. Theme font references (asciiTheme etc.) are untouched — use #apply_font_scheme for those.

  • from (String) —

    Font family to replace (exact match)

  • to (String) —

    Replacement font family

Returns:

  • (Integer) —
