|
|||
Unlike ocamllex, lexers work on stream of Unicode codepoints, not
|
||||
bytes.
|
||||
|
||||
Like ocamllex, sedlex uses **longest match** with **first rule priority**:
|
||||
|
||||
- The lexer always tries to match the longest possible prefix of the
|
||||
input. It does so by continuing to read characters as long as some
|
||||
rule can still match a longer string, while remembering the last
|
||||
position at which a rule did match.
|
||||
|
||||
- When two or more rules match the same longest prefix (a tie), the
|
||||
rule that appears first in the `match%sedlex` definition wins. For
|
||||
example, given the rules `| "if" -> ...` and `| Plus ('a'..'z') -> ...`,
|
||||
the input `"if"` is matched by the first rule because it is listed
|
||||
first, even though the second rule also accepts `"if"`.
|
||||
|
||||
The actions can call functions from the Sedlexing module to extract
|
||||
(parts of) the matched lexeme, in the desired encoding.
