Pango.LogAttr

Fields

Name	Type	Access	Description
backspace_deletes_character	int	r/w	if set, backspace deletes one character rather than the entire grapheme cluster. This field is only meaningful on grapheme boundaries (where is_cursor_position is set). In some languages, the full grapheme (e.g. letter + diacritics) is considered a unit, while in others, each decomposed character in the grapheme is a unit. In the default implementation of Pango.break_(), this bit is set on all grapheme boundaries except those following Latin, Cyrillic or Greek base characters.
is_char_break	int	r/w	if set, can break here when doing character wrapping
is_cursor_position	int	r/w	if set, cursor can appear in front of character. i.e. this is a grapheme boundary, or the first character in the text. This flag implements Unicode’s Grapheme Cluster Boundaries semantics.
is_expandable_space	int	r/w	is a whitespace character that can possibly be expanded for justification purposes.
is_line_break	int	r/w	if set, can break line in front of character
is_mandatory_break	int	r/w	if set, must break line in front of character
is_sentence_boundary	int	r/w	is a sentence boundary. There are two ways to divide sentences. The first assigns all inter-sentence whitespace/control/format chars to some sentence, so all chars are in some sentence; is_sentence_boundary denotes the boundaries there. The second way doesn’t assign between-sentence spaces, etc. to any sentence, so is_sentence_start/is_sentence_end mark the boundaries of those sentences.
is_sentence_end	int	r/w	is first str after a sentence. Note that in degenerate cases, you could have both is_sentence_start and is_sentence_end set for some character. (e.g. no space after a period, so the next sentence starts right away)
is_sentence_start	int	r/w	is first character in a sentence
is_white	int	r/w	is whitespace character
is_word_boundary	int	r/w	is a word boundary, as defined by UAX#29. More specifically, means that this is not a position in the middle of a word. For example, both sides of a punctuation mark are considered word boundaries. This flag is particularly useful when selecting text word-by-word. This flag implements Unicode’s Word Boundaries semantics.
is_word_end	int	r/w	is first non-word str after a word Note that in degenerate cases, you could have both is_word_start and is_word_end set for some character.
is_word_start	int	r/w	is first character in a word
