PEGTL 2.2.0

• Added possibility for actions' apply() or apply0()-methods to return a bool which is then used to determine overall success or failure of the rule to which such an action was attached.
• Added <tao/pegtl/contrib/parse_tree.hpp> and the examples/parse_tree.cpp application that shows how to build a parse tree. The example goes beyond a traditional parse tree and demonstrates how to select which nodes to include in the parse tree and how to transform the nodes into an AST-like structure.
• Added bom rules for UTF-8, UTF-16 and UTF-32.
• Added some missing includes for config.hpp.
• Added automated testing with Clang 5.
• Added automated testing with Xcode 9.

PEGTL 2.1.4

• Fixed shadow warning.

PEGTL 2.1.3

• Fix raw_string with optional parameters.

PEGTL 2.1.2

• Bump version.

PEGTL 2.1.1

• Fixed build with MinGW on Windows.
• Added automated testing with MinGW.

Note: This version accidentally identifies as 2.1.0 - this has been fixed by version 2.1.2.

PEGTL 2.1.0

• Added optional template parameters to raw_string for rules that the content must match.
• Added new contrib rules rep_one_min_max and ellipsis.
• Fixed broken TAOCPP_PEGTL_KEYWORD macro.
• Fixed a bug in the contrib HTTP grammar which prevented it from parsing status lines in some cases.
• Fixed build with MinGW-w64 on Windows.
• Added automated testing with MinGW-w64.
• Added automated testing with GCC 7.

PEGTL 2.0.0

• Project

  • Migrated to "The Art of C++".
  • A migration guide for porting applications from 1.y to 2.z is available.
  • Version 2.z can be installed and used in parallel to version 1.y of the PEGTL.
  • The semantics of all parsing rules and grammars is the same as for versions 1.y.

  • Added support for custom incremental input readers.
  • Added support for parsing C streams, i.e. std::FILE*.
  • Added support for parsing C++ streams, i.e. std::istream.
  • Added support for different EOL-styles.
  • Renamed class position_info to position.
  • Added the byte position to input classes and position.
  • Added fast parsing without line counting (except in errors).
  • Refactored the input class into multiple input classes.
  • Refactored the file parser classes into input classes.
  • Refactored the handling of nested parsing.
  • Removed the begin() member from class position.
  • Removed most parsing front-end functions.

• Parsing Rules

  • Added combinator class minus.
  • Added ASCII rule class keyword.
  • Added string rules for UTF-8, UTF-16 and UTF-32.
  • Added apply, apply0 and if_apply rules for intrusive actions.
  • Added incremental input support rules discard and require.

• String Macros

  • Renamed to TAOCPP_PEGTL_(I)STRING.
  • Increased allowed string length to 512.
  • Allowed embedded null bytes.

  • Replaced layered matching with superior Duseltronik™.
  • Reduced template instantiation depth.
  • Added support for CMake.
  • Added automated testing with Visual Studio 2015 and 2017.
  • Added automated testing with Android 5.1, NDK r10e.

PEGTL 1.3.1

• Fixed unit test to use eol instead of hard-coded line ending.

PEGTL 1.3.0

• Tentative Android compatibility.
• Fixed build with MinGW on Windows.
• Changed file reader to open files in binary mode.
• Changed eol and eolf to accept both Unix and MS-DOS line endings.
• Optimised bumping the input forward and removed little used bump function.
• Simplified grammar analysis algorithm (and more analyze() tests).

PEGTL 1.2.2

• Improved the JSON grammar and JSON string escaping.
