Summary

• Adds a new docs format subcommand for applying rich text formatting to existing text in Google Docs
• Adds formatting flags (--font-family, --font-size, --text-color, --bg-color, --bold, --italic, --underline, --strikethrough, --alignment, --line-spacing) to docs write
• Uses Google Docs API batchUpdate with UpdateTextStyle and UpdateParagraphStyle requests

docs format command

Target text by content match or apply to entire document:

# Format specific text
gog docs format <docId> --match "Hello World" --bold --text-color "#FF0000"

# Format all occurrences
gog docs format <docId> --match "important" --match-all --underline --bg-color "#FFFF00"

# Format entire document
gog docs format <docId> --font-family "Georgia" --font-size 14

docs write formatting

Apply formatting after writing content:

gog docs write <docId> --text "Hello" --font-family "Arial" --font-size 16 --text-color "#003399"

Implementation

• FormattingOpts struct + buildFormattingRequests() in docs_formatter.go — builds typed API requests with proper field masks
• DocsFormatCmd in docs_edit.go — reuses existing findTextInDoc/findTextMatches for text search
• Reuses existing parseHexColor from docs_sed_helpers.go via hexToOptionalColor wrapper
• Supports ForceSendFields for explicitly setting boolean values to false (e.g., removing bold)

Test plan

• gog docs format <id> --match "text" --bold --text-color "#FF0000" — verify bold red text in browser
• gog docs format <id> --match "text" --match-all --underline — verify all occurrences underlined
• gog docs format <id> --alignment center — verify whole doc centered
• gog docs write <id> --text "Hello" --font-family Georgia --font-size 16 — verify font applied
• gog docs format <id> --match "nonexistent" — verify error message
