Changelog

Unreleased

v4.2.0

Added

• Support for passing the size of the input string to the matching algorithm.
  • Call pt_match_n instead of pt_match to pass the string size.
  • pt_match simply forwards the call to pt_match_n passing SIZE_MAX as the string size.
  • A new PT_OP_CUSTOM_MATCHER_N operation was added for custom matchers that receive the input string size. Use the PT_CUSTOM_MATCHER_N macro or CUSTOM_MATCHER_N alias to create such expression.

v4.1.0

Added

• Support for passing custom malloc/ realloc / free functions in pt_match_options

Fixed

• Compilation and support for literals, case insensitive and set expressions when PT_ELEMENT_TYPE is not char

Deprecated

• PT_MALLOC, PT_REALLOC and PT_FREE macros. Pass custom memory functions in pt_match_options instead.

v4.0.0

Changed

• Refactor project as a single header implementation
• Split Quantifier Expressions into At Least and At Most expressions
• Make PT_DATA type configurable, just #define PT_DATA <your type here>
• Add Action Expressions to simplify implementation and make code more readable
• Reimplement match algorithm using recursion. This is much faster than the previous approach.
• Make Expressions be layed out contiguously in memory and remove heap based creation and destruction of them
• Grammar literals are now definable at compile-time

v3.0.0

Added

• Add Byte expression

Changed

• Change actions to receive the capture with pointer and size, instead of pointer to input string, start and end of capture
• Change Character Class Expressions to use only functions defined in ctype.h
• Change Range Expressions to use 2 bytes instead of a NULL terminated string
• Use Grammars without malloc'ing them.

v2.1.0

Added

• Populate pt_match_result.data.i with the first syntactic error code when syntactic errors occur

v2.0.1

Fixed

• Put extern "C" declarations in inner headers.

v2.0.0

Changed

• ABI change on pt_match_options
• Included Case Insensitive and Character Class Expressions (the old Custom Matcher)
• Changed Custom Matcher Expressions to allow operating on strings, also receiving userdata

v1.2.7

Changed

• Removed all the Action sequence computation, as Actions are already stacked in the right sequence. Running actions is now iterative, O(n) and use far less memory.

v1.2.6

Fixed

• Fixed SEQ and OR expression macros on C++, turns out they behave differently about temporary lifetime of arrays.

v1.2.5

Fixed

• Fixed SEQ and OR expression macros to compile on both C and C++ using preprocessor macros and initializer_list directly on macro-on.h.

v1.2.4

Fixed

• Added extern "C" declaration on pega-texto.h for using in C++.

v1.2.3

Fixed

• Fixed validation error code emmited when pt_is_nullable returned true, as it may find an error other than PT_VALIDATE_LOOP_EMPTY_STRING.

v1.2.2

Fixed

• Added NULL string check on match.

v1.2.1

Fixed

• Fixed validation error on empty SEQ and OR Expressions, which are valid with a NULL pointer.

v1.2.0

Chaged

• Macros for Expressions to not own memory buffers
• Empty SEQ and OR Expressions don't allocate a 0-byte buffer anymore

Fixed

• Fixed validation error on Non-terminal cycles.

v1.1.1

Fixed

• Fixed validation error on Non-terminal cycles.

v1.1.0

Added

• Basic error handling support.

v1.0.0

Added

• Expressions, Grammars, parsing, validation, actions.
