Functions
-
auto byte_at(std::
string_view text, grapheme_index_t cell) → byte_offset_t noexcept - Byte offset at the
cell-th grapheme cluster (clamped to text.size()). -
auto byte_at_column(std::
string_view text, width_t column) → byte_offset_t noexcept - Byte offset for the grapheme cluster at
column. -
auto byte_offset(std::
size_t n) → byte_offset_t constexpr noexcept - Construct a byte offset.
-
auto cell_at(std::
string_view text, byte_offset_t byte) → grapheme_index_t noexcept - Grapheme cluster index for a byte offset, snapped to the previous boundary.
-
auto cluster_width(std::
string_view cluster) → width_t noexcept - Display width of one grapheme cluster.
-
auto column_at(std::
string_view text, byte_offset_t byte) → width_t noexcept - Display column for a byte offset, snapped to the previous boundary.
-
auto complete_words_prefix_size(std::
string_view text) → std:: size_t noexcept - Size in bytes of the prefix that ends on a word boundary.
-
auto count(std::
string_view text) → grapheme_index_t noexcept - Number of grapheme clusters in
text. -
auto decode(std::
string_view text, byte_offset_t byte) → Decoded noexcept -
auto display_width(std::
string_view text) → width_t noexcept - Display width of all grapheme clusters in
text. -
auto floor_boundary(std::
string_view text, byte_offset_t byte) → byte_offset_t noexcept - Byte offset of the nearest grapheme boundary at or before
byte. -
auto grapheme_index(std::
size_t n) → grapheme_index_t constexpr noexcept - Construct a grapheme index.
-
auto is_line_break(std::
string_view cluster) → bool noexcept - True when a grapheme cluster is a line break.
-
auto is_word_separator(std::
string_view cluster) → bool noexcept - True when a grapheme cluster should separate words.
-
auto next(std::
string_view text, byte_offset_t byte) → byte_offset_t noexcept -
auto operator-(byte_offset_t a,
byte_offset_t b) → std::
size_t constexpr noexcept - Difference between two byte offsets.
-
auto prev(std::
string_view text, byte_offset_t byte) → byte_offset_t noexcept - auto regional_indicator(utf8proc_int32_t cp) → bool noexcept
-
auto segments(std::
string_view text) → segment_view noexcept - Return a segment range over borrowed text.
-
auto words(std::
string_view text) → word_view noexcept - Return a word range over borrowed text.
