Changelog: ========== - Added capturing groups with leftmost greedy semantics: - Added non-capturing groups: - Regenerated Unicode include header to support a newer standard - Published TDFA paper: https://arxiv.org/abs/2206.01398, co-authored with Angelo Borsotti - Removed experimental algorithms that are superseded by TDFA(1) and generally less efficient: - Fixed parsing of raw UTF-8 characters in Flex compatibility mode - Added header file to the dependencies generated with "--depfile" option - Fixed stack overflow on large regular expressions by rewriting recursive functions in iterative form and limited stack to 256K on GithubActions CI - Added minimal http://bazel.build integration - Added configure option "--enable-parsers" that regenerates bison parsers - Added CMake option "RE2C_REBUILD_PARSERS" - Moved the entire codebase to C++11. - Added uniform error handling (return codes are now properly checked and returned to the caller). - Reorganized codegen subsystem in four well-defined phases (analyze, generate, fixup, render) and separated codegen from parsing phase. - Improved memory allocation by using slab allocators instead of global free lists. - Moved to pure API for bison parsers. - Unified code style. - Added "--verbose" flag to run_tests.py and suppressed verbose output by default. - Multiple improvements of continuous testing with GithubActions.
