Character Classification

val is_cased : 
  Unsigned.uint32 ->
  int
    Bindings.Libregexp__c_generated_functions__Function_description__Functions.return

Check if character has uppercase/lowercase variants (Cased property)

val is_case_ignorable : 
  Unsigned.uint32 ->
  int
    Bindings.Libregexp__c_generated_functions__Function_description__Functions.return

Check if character is ignored during case mapping (Case_Ignorable)

val is_id_start : 
  Unsigned.uint32 ->
  int
    Bindings.Libregexp__c_generated_functions__Function_description__Functions.return

Check if character can start an identifier (ID_Start)

val is_id_continue : 
  Unsigned.uint32 ->
  int
    Bindings.Libregexp__c_generated_functions__Function_description__Functions.return

Check if character can continue an identifier (ID_Continue)

val is_space : 
  int ->
  bool
    Bindings.Libregexp__c_generated_functions__Function_description__Functions.return

Check if character is whitespace (works for all codepoints)

Case Conversion

val case_conv : 
  Unsigned.uint32 Ctypes_static.ptr ->
  Unsigned.uint32 ->
  int ->
  int
    Bindings.Libregexp__c_generated_functions__Function_description__Functions.return

Convert character case. conv_type: 0 = uppercase, 1 = lowercase, 2 = case folding Returns number of output codepoints (1-3)

val canonicalize : 
  Unsigned.uint32 ->
  int ->
  int
    Bindings.Libregexp__c_generated_functions__Function_description__Functions.return

Canonicalize character for case-insensitive regex matching. is_unicode: 1 = full Unicode folding, 0 = ASCII only

Normalization

val normalize : 
  Unsigned.uint32 Ctypes_static.ptr ->
  int ->
  int ->
  Unsigned.uint32 Ctypes_static.ptr Ctypes_static.ptr ->
  int
    Bindings.Libregexp__c_generated_functions__Function_description__Functions.return

Normalize Unicode string. n_type: 0 = NFC, 1 = NFD, 2 = NFKC, 3 = NFKD Returns length of output, or -1 on error

val normalize_free : 
  Unsigned.uint32 Ctypes_static.ptr ->
  unit
    Bindings.Libregexp__c_generated_functions__Function_description__Functions.return

Free buffer allocated by normalize
