3.4 (2025-03-28)

• Make the library compatibility with ppxlib.0.36 (#166)

3.3 (2024-10-29)

• Add support for unicode 16.0.0 (#157)
• Add API for retrieving start and stop positions separately (#155)

3.2 (2023-06-28):

• Restore compatibility with OCaml 4.08
• Use Sedlexing.{Utf8,Utf16}.from_gen to initialize UTF8 (resp. UTF16) lexing buffers from string.
• Delay raising Malformed until actually reading the malformed part of the imput. (#140)
• Count lines in all cases (#130). Previously, certain functions for initiating the lexical buffer would disable lines counting.
• Check and fix invariants from Cset. The codebase was not respecting invariants documented in the Cset module which could break code relying on it. The code generated by sedlex.ppx could be affected.
• Do not rely on comments from unicode UCD files
• Add API to track position in bytes. Should be opt-in and backward compatible. (#146)

3.1:

• Fix directly nested sedlex matches (@smuenzel, PR #117, fixes: #12)
• Use explicit stdlib in generated code (@hhugo, PR #122, fixes: #115)
• Preserve location of lexbuf (@hhugo, PR #118, fixes: #19)
• Don't use gen to consume channels (@hhugo, PR #124, fixes: #45)
• New expect_test testsuite (@hhugo, PR #124)
• Properly recognize malformed truncated input (@hhugo, PR #124)
• Raise Malformed instead of Invalid_arg (@hhugo, PR #126, fixes: #91)
• Updated unicode support to 15.0.0
