Module `Lang.Utf`Source

This module provides facilities for translating language-based locations to protocol-based locations.

After a long discussion (thanks Léo !), we have decided that the best is to have `Lang.Point` to store columns offset in the values that are native to the protocol under consideration, set by the upper layers.

This scheme kind of follows what we have done since the start with coq-lsp.

Future work: support setting protocol enconding

Unicode terminology refresher:

character, code point: The real unicode character
byte or 16bit offset / code unit: The encoded version

Sourcetype utf8_string = string

Sourcetype char = int

Sourcetype utf8_index = int

Sourcetype utf16_index = int

Source

val utf16_offset_of_utf8_offset : 
  line:utf8_string ->
  offset:utf8_index ->
  utf16_index

UTF-16 offset from UTF-8 offset; line is enconded in UTF-8

Source

val utf8_offset_of_utf16_offset : 
  line:utf8_string ->
  offset:utf16_index ->
  utf8_index

Get the byte position of a code point indexed in UTF-16 code units in a UTF-8 encoded utf8_string. Returns the position of the last character if the UTF-16 position was out of bounds.

To UTF-16 offsets

Sourceval length_utf16 : utf8_string -> utf16_index

Length in UTF-16 code points

Not used anywhere, remove?

Number of characters in the utf-8-encoded utf8_string.

Converstion from char to UTF-8/16

Sourceval utf8_offset_of_char : line:utf8_string -> char:char -> utf8_index option

UTF-8 Char to byte index position; line is enconded in UTF-8

Sourceval utf16_offset_of_char : line:utf8_string -> char:int -> utf16_index

Get the utf16 position of a code point indexed in unicode code points in a UTF-8 encoded utf8_string. The position must be in bounds.

Converstion to char from UTF-8/16

Sourceval char_of_utf8_offset : line:utf8_string -> offset:utf8_index -> char option

Byte index to character position also called a codepoint, line is encoded in UTF-8

Sourceval char_of_utf16_offset : line:utf8_string -> offset:utf16_index -> char

Get the unicode position of a code point indexed in UTF-16 code units in a utf-8 encoded utf8_string. Returns the position of the last character if the utf-16 position was out of bounds.

Sourceval next : string -> int -> int
