2.0.3 (2020-08-22) ~~~~~~~~~~~~~~~~~~ - Fix issues when building re2c as a CMake subproject (`#302 <https://github.com/skvadrik/re2c/pull/302>`_: - Final corrections in the SIMPA article "RE2C: A lexer generator based on lookahead-TDFA", https://doi.org/10.1016/j.simpa.2020.100027 2.0.2 (2020-08-08) ~~~~~~~~~~~~~~~~~~ - Enable re2go building by default. - Package CMake files into release tarball. 2.0.1 (2020-07-29) ~~~~~~~~~~~~~~~~~~ - Updated version for CMake build system (forgotten in release 2.0). - Added a short article about re2c for the Software Impacts journal. 2.0 (2020-07-20) ~~~~~~~~~~~~~~~~ - Added new code generation backend for Go and a new ``re2go`` program (`#272 <https://github.com/skvadrik/re2c/issues/272>`_: Go support). Added option ``--lang <c | go>``. - Added CMake build system as an alternative to Autotools (`#275 <https://github.com/skvadrik/re2c/pull/275>`_: Add a CMake build system (thanks to ligfx), `#244 <https://github.com/skvadrik/re2c/issues/244>`_: Switching to CMake). - Changes in generic API: + Removed primitives ``YYSTAGPD`` and ``YYMTAGPD``. + Added primitives ``YYSHIFT``, ``YYSHIFTSTAG``, ``YYSHIFTMTAG`` that allow to express fixed tags in terms of generic API. + Added configurations ``re2c:api:style`` and ``re2c:api:sigil``. + Added named placeholders in interpolated configuration strings. - Changes in reuse mode (``-r, --reuse`` option): + Do not reset API-related configurations in each `use:re2c` block (`#291 <https://github.com/skvadrik/re2c/issues/291>`_: Defines in rules block are not propagated to use blocks). + Use block-local options instead of last block options. + Do not accumulate options from rules/reuse blocks in whole-program options. + Generate non-overlapping YYFILL labels for reuse blocks. + Generate start label for each reuse block in storable state mode. - Changes in start-conditions mode (``-c, --start-conditions`` option): + Allow to use normal (non-conditional) blocks in `-c` mode (`#263 <https://github.com/skvadrik/re2c/issues/263>`_: allow mixing conditional and non-conditional blocks with -c, `#296 <https://github.com/skvadrik/re2c/issues/296>`_: Conditions required for all lexers when using '-c' option). + Generate condition switch in every re2c block (`#295 <https://github.com/skvadrik/re2c/issues/295>`_: Condition switch generated for only one lexer per file). - Changes in the generated labels: + Use ``yyeof`` label prefix instead of ``yyeofrule``. + Use ``yyfill`` label prefix instead of ``yyFillLabel``. + Decouple start label and initial label (affects label numbering). - Removed undocumented configuration ``re2c:flags:o``, ``re2c:flags:output``. - Changes in ``re2c:flags:t``, ``re2c:flags:type-header`` configuration: filename is now relative to the output file directory. - Added option ``--case-ranges`` and configuration ``re2c:flags:case-ranges``. - Extended fixed tags optimization for the case of fixed-counter repetition. - Fixed bugs related to EOF rule: + `#276 <https://github.com/skvadrik/re2c/issues/276>`_: Example 01_fill.re in docs is broken + `#280 <https://github.com/skvadrik/re2c/issues/280>`_: EOF rules with multiple blocks + `#284 <https://github.com/skvadrik/re2c/issues/284>`_: mismatched YYBACKUP and YYRESTORE (Add missing fallback states with EOF rule) - Fixed miscellaneous bugs: + `#286 <https://github.com/skvadrik/re2c/issues/286>`_: Incorrect submatch values with fixed-length trailing context. + `#297 <https://github.com/skvadrik/re2c/issues/297>`_: configure error on ubuntu 18.04 / cmake 3.10 - Changed bootstrap process (require explicit configuration flags and a path to re2c executable to regenerate the lexers). - Added internal options ``--posix-prectable <naive | complex>``. - Added debug option ``--dump-dfa-tree``. - Major revision of the paper "Efficient POSIX submatch extraction on NFA". ---- 1.3x ---- 1.3 (2019-12-14) ~~~~~~~~~~~~~~~~ - Added option: ``--stadfa``. - Added warning: ``-Wsentinel-in-midrule``. - Added generic API primitives: + ``YYSTAGPD`` + ``YYMTAGPD`` - Added configurations: + ``re2c:sentinel = 0;`` + ``re2c:define:YYSTAGPD = "YYSTAGPD";`` + ``re2c:define:YYMTAGPD = "YYMTAGPD";`` - Worked on reproducible builds (`#258 <https://github.com/skvadrik/re2c/pull/258>`_: Make the build reproducible). ---- 1.2x ---- 1.2.1 (2019-08-11) ~~~~~~~~~~~~~~~~~~ - Fixed bug `#253 <https://github.com/skvadrik/re2c/issues/253>`_: re2c should install unicode_categories.re somewhere. - Fixed bug `#254 <https://github.com/skvadrik/re2c/issues/254>`_: Turn off re2c:eof = 0. 1.2 (2019-08-02) ~~~~~~~~~~~~~~~~ -
