Changelog

v0.6.1

  • #5, ec2233e - Avoid panic on spelling inconsistencies errors.
  • #7, bff52b5 - Fix the calculation of inverse bracket expressions.

Changes

v0.6.0

  • 12bfeb8 - Refactor the UCD file parsers.
  • 2359623 - Fix key of generalCategoryCodePoints map. Use the abbreviation cn of the general category value unassigned as a key of generalCategoryCodePoints map.
  • bedf0c1, 6ebbc8f, e9af227, 301d02d - Support White_Space, Lowercase, Uppercase, Alphabetic, and Script properties. (Meet RL1.2 of UTS #18 partially)
  • 10d0c5d - Make character properties available in an inverse expression (Make [^\p{...}] available).
  • 5ebc2f4 - Move all UCD-related processes to ucd package.
  • cb9d92f - Make contributory properties unavailable except internal use.
  • f0870a4 - Remove default value's code points of General_Category.
  • 847bcc7 - Move UTF8-related processes to utf8 package.
  • 19b68a5, e3195d8, d595194, 4321811 - Use CPTree and byteTree instead of AST. CPTree represents characters in code points, while byteTree represents characters in UTF-8 byte sequences. In the past, when we excluded a part of a character range, like [^...], we needed to subtract byte sequences from each other. This process is complicated. Therefore, we simplified the UTF-8 related processing by calculating the character range in code points and then converting it to UTF-8 byte sequences.
  • 46d49df - Make character properties unavailable in bracket expressions.
  • 3ec662c - Add tests of compiler/parser package.
  • a630029 - Remove --lex-spec option from maleeni compile command.

Changes

v0.5.1

  • fe865a8 - Generate constant values representing mode IDs, mode names, kind IDs, and kind names.
  • 7be1d27 - Add name field to the lexical specification. maleeni uses the name field to generate a source file name of the lexer. For instance, when the name is my_lex, the source file of the lexer is named my_lex_lexer.
  • cf4f533 - Keep the order of AST nodes constant. This change is intended to output the same transition table for the same inputs.
  • 9f3a334 - Remove --debug option from compile command.
  • a8ed73f - Disallow upper cases in an identifier.
  • 12658e0 - Format the source code of a lexer maleeni-go generates.
  • 60a5089 - Remove the ModeName and KindName fields from the driver.Token struct.

Changes

v0.5.0

  • 6332aaf - Remove --debug option from maleeni lex command.
  • f691b5c, 96a555a - Add maleeni-go command to generate a lexer that recognizes a specific lexical specification.

Changes

v0.4.0

Changes

v0.3.0

Changes

v0.2.0

  • 7e169f8 - Support passive mode transition.
  • a30fe0c - Add a function spec.EscapePattern to escape the special characters that appear in patterns.

Changes

v0.1.0

  • maleeni v0.1.0, this is the first release, supports the following features.
    • Definitions of lexical specifications by regular expressions
      • Alternation: |
      • Dot expression: .
      • Bracket expressions: [...], [^...]
      • Code point expressions: \u{...}
      • Character property expressions: \p{...}
      • Repetition: *, +, ?
      • Grouping: (...)
      • Fragment: \f{...}
    • Mode transition
