Changelog

0.11.0

• Migrates custom lexer logic to alex-tools package
• Floating-point and integers distinguished in Exp type

0.10.0

• Track the end positions of tokens and the AST in addition to the start

0.9.0

• Transition to parsing Text using a simplified alex lexer and happy parser

0.8.0

• We can now parse Unicode strings from UTF-8 encoded files. By default these literals are not interpreted, and we have StringLiteral.interpretStringLiteral for interpretation and StringLiteral.constructStringLiteral for constructing Lua string literals from UTF-8 encoded ByteStrings.

  Main invariant is that if you print a parsed Lua string, it should be printed the same way. (including long strings)

• Empty statements(EmptyStat) are now printed by pretty printer to avoid ambiguous printing. Previously these two statements were printed the same:

  f();(f)()
  f()(f)()
  

  But the first line does not have the parse ambiguity(3 function applications in one statement or two function application statements).

• Forgotten Annotated instance for Name implemented.

• Some warnings are fixed for GHC < 7.10.

0.7.1

• Integer division parsing fixed.

0.7.0

• language-lua now supports Lua 5.3.
• Some warnings printed with base >= 4.8 are fixed.

0.6.3.3

• Some bugs related with assignment statement parsing are fixed(#22).
• Wrong error message for expected == operator is fixed(#23).

0.6.3.2

• Build fixed for GHC 7.10.

0.6.3.1

• Build-tools field is added to Cabal file.

0.6.3

• Fixed some issues with string parsing. (#17)
• Added named variant of text parsers to allow specifying source names. (#18)

0.6.2.1

• Missing test files are added to Cabal package.

0.6.2

• base dependency is relaxed for GHC 7.10. Note that alex version

  3.1.4 is required to compile with GHC 7.10.

0.6.1

• Generic and NFData instances are implemented for syntax trees.

0.6.0

• Fixed a long string literal parsing bug which was causing long strings to terminate at wrong points.
• \z escape characters in strings are now scanned and interpreted correctly.
• This is first version that parses all of Lua 5.2.2 test suite.

0.5.0

• 2-years-old operator parsing bug fixed. Chained/nested operator expressions are now properly parsed.

0.4.6

• Language.Lua.Annotated.Lexer module exposed.

0.4.5

• Fixed a bug that made lexer accept invalid escape sequences in strings.
• Strings are now interpreted -- string "\n" is now parsed to Haskell string "\n", instead of "\\n".
• Fixed character code parsing.

0.4.4

• Printer now takes operator precedences into account while printing Binop and Unop expressions and prints parenthesis as necessary.
• Printer now does not put line break in Binop expressions.

0.4.3

• Data and Typeable instances are implemented for syntax tree.

0.4.2

• More tweaks in pretty printer.
• Started using 2 spaces for indentation(instead of 4 as before).

0.4.1

• Some tweaks in pretty-printer.

0.4.0

• Table and FunDef nodes are removed from simplified syntax.

0.3.1

• Fixed incorrectly exported name exp in Language.Lua.Parser module.

0.3.0

• Added non-annotated syntax to make code-generation easier.

0.2.3

• Minor internal changes.

0.2.2

• Some tweaks in pretty-printer.

0.2.0

• Syntax tree is annotated. All parsers(parseText, parseFile) annotate resulting tree with source positions.
