Changelog for NimbleParsec

v1.4.2 (2025-01-21)

Enhancements

  • Remove more warnings on Elixir v1.18+

v1.4.1 (2025-01-15)

Enhancements

  • Remove warnings on Elixir v1.18+

v1.4.0 (2023-11-08)

Enhancements

  • Remove warnings and require Elixir v1.12

v1.3.1 (2023-04-30)

Bug fixes

  • Make error messages consistent across Elixir versions
  • Ensure integer(max: ...) also sets a minimum of 1
  • Do not lose context on repeat_while

v1.3.0 (2023-03-27)

Deprecations

  • Deprecate returning a {acc, context} from quoted_post_traverse and quoted_pre_traverse. Return {rest, acc, context} instead.

Bug fixes

  • Avoid compile warnings with negative lookahead
  • Fix clause warning for integer combinator

v1.2.3 (2022-02-28)

Enhancements

  • Allow :export_combinator in defparsec

v1.2.2 (2022-02-12)

Enhancements

  • Allow rest to be returned from post_traverse/pre_traverse

v1.2.1 (2022-01-26)

Bug fixes

  • Improve typespecs

v1.2.0 (2021-11-07)

Enhancements

  • Add generator support to NimbleParsec: it now generates code that matches a combinator

Bug fixes

  • Fix using eventually with constructs that can accumulate
  • Fix lookahead combinators running in reverse order
  • Raise on invalid min for integer

v1.1.0 (2020-10-02)

Enhancements

  • Add defcombinator and support for remote parsec. This allows larger parsers to be broken over multiple modules to speed up compilation by leveraging parallelism.

v1.0.0 (2020-09-25)

Enhancements

  • Allow byte_offset to be given to :line

v0.6.0 (2020-05-25)

NimbleParsec v0.6.0 requires Elixir v1.6+.

Bug fixes

  • Avoid unused variable warnings

v0.5.3 (2019-12-11)

Enhancements

  • Add eventually/2 combinator

v0.5.2 (2019-11-10)

Enhancements

  • Optimize repeat with initial lookahead
  • Add @spec to parsec/2

v0.5.1 (2019-08-04)

Enhancements

  • Remove dialyzer warnings from emitted code
  • Optimize lookahead with choice
  • Support min: 0 on utf8_string/ascii_string
  • Remove compiler warnings in code generated by mix nimble_parsec.compile
  • Add @spec to combinators

v0.5.0 (2018-12-12)

Enhancements

  • Introduce pre_traverse/3
  • Introduce lookahead/2 and lookahead_not/2 which accepts combinators
  • Introduce eos/1 (end of string combinator)

Backwards incompatible changes

  • Deprecate traverse/3 in favor of post_traverse/3
  • repeat_until/3 has been removed in favor of repeat/2 with lookahead_not/2 (see repeat_while/3 docs for an example)
  • lookahead/2 with a call has been removed as it can be easily achieved with a post_traverse/3

v0.4.0 (2018-08-10)

Enhancements

  • Add defcombinatorp and clarify the role of defparsecp

v0.3.2 (2018-06-02)

Bug fixes

  • Fix compilation error for certain combinations of ascii_string/utf8_string + traverse
  • Respect the label construct when wrapping a choice

v0.3.1 (2018-04-10)

Bug fixes

  • Avoid exponential compilation time when line break is unknown

v0.3.0 (2018-04-08)

Enhancements

  • Add unwrap, tag and unwrap_and_tag
  • Add nimble_parsec.compile to compile parsers without a NimbleParsec dependency

v0.2.2 (2018-03-08)

Bug fix

  • Ensure multiple runtime traversals compose

v0.2.1 (2018-03-04)

Bug fix

  • Do not duplicate entries in integer/ascii_string/utf8_string

v0.2.0 (2018-03-04)

Enhancements

  • Support parser combinator contexts and return them in ok/error tuples
  • Add ascii_string/3 and utf_string/3 combinators
  • Add lookahead/2 combinator
  • Rename literal/2 to string/2
  • Add line/2 and byte_offset/2 combinators
  • The MFA given to repeat_while/3 now receives the accumulator, context, line, and byte_offset values and must return {:cont, context} | {:halt, context}
  • The MFA given to quoted_repeat_while/3 now receives the accumulator, context, line, and byte_offset values and must return {:cont, context} | {:halt, context}
  • The MFA given to traverse/3 now receives the rest, accumulator, context, line, and byte_offset values and must return {acc, context} | {:error, reason}
  • The MFA given to quoted_traverse/3 now receives the ASTs for the rest, accumulator, context, line, and byte_offset and must return {acc, context} | {:error, reason}
  • Instead of line as a positive integer, we now track {line, line_offset} where line is the same as before and line_offset is the byte offset after the new line
  • Instead of column as a positive integer, we now track byte_offset as a non-negative integer

v0.1.0 (2018-03-02)

  • First release.
