Changelog
=========
----
2.2x
----
2.2 (2021-08-01)
~~~~~~~~~~~~~~~~
- Added named blocks and block lists in directives.
- Added local blocks ``/*!local:re2c ... */``.
- Added in-block ``!include`` directive.
- Added in-block ``!use`` directive.
- Allowed reusable blocks without ``-r --reusable`` option.
- Allowed customizing the generated code with configurations for directives
``max:re2c``, ``maxnmatch:re2c``, ``stags:re2c``, ``mtags:re2c`` and
``types:re2c`` (see directive descriptions for details).
- Forbid arbitrary text at the end of ``max:re2c`` directive. This may break
backwards compatibility, although it is unlikely that this was used by anyone.
The change was necessary in order to allow customization of the generated code
with configurations.
- Deprecated configurations ``flags:i``, ``flags:no-debug-info`` in favour of
the global options ``-i``, ``--no-debug-info``.
- Reimplemented re2c test runner in Python (thanks to
`Serghei Iakovlev <https://github.com/sergeyklay>`_). Improved integration
with GitHub Actions.
- Changes in the experimental libre2c library: added new algorithms that
construct t-string or extract submatch on all repetitions; added TDFA
benchmark written in Java by Angelo Borsotti.
- Updated documentation.
----
2.1x
----
2.1.1 (2021-03-27)
~~~~~~~~~~~~~~~~~~
- Added missing CMakeLists.txt to release tarballs
(`#346 <https://github.com/skvadrik/re2c/issues/346>`_).
2.1 (2021-03-26)
~~~~~~~~~~~~~~~~
- Added GitHub Actions CI for Linux, macOS and Windows and fixed numerous build
issues on those platforms (thanks to
`Serghei Iakovlev <https://github.com/sergeyklay>`_).
- Added benchmarks for submatch extraction in lexer generators (ragel vs.
kleenex vs. re2c with TDFA(0), TDFA(1) or sta-DFA algorithms).
+ New Autotools (configure) options: ``--enable-benchmarks``,
``--enable-benchmarks-regenerate``
+ New CMake options: ``-DRE2C_BUILD_BENCHMARKS``, ``-DRE2C_REGEN_BENCHMARKS``
+ New `json2pgfplot.py
<https://github.com/skvadrik/re2c/blob/master/benchmarks/json2pgfplot.py>`_
script that converts benchmark results in JSON to a PDF with bar charts
- Added option ``--depfile <filename>`` to generate build dependency files
(allows to track ``/*!include:re2c*/`` dependencies in the build system).
- Added option ``--fixed-tags <none | all | toplevel>`` and improved fixed-tag
optimization to work with nested tags.
- Added lzip to the distribution tarballs.
- Added registerless-TDFA algorithm in the experimental libre2c library.
- Explicitly disallowed invalid configuration when ``-f``, ``--storable-state``
option is used, but ``YYFILL`` is disabled
(`#306 <https://github.com/skvadrik/re2c/issues/306>`_).
- Fixed bug in UTF-8 decode for 4-bytes rune
(`#307 <https://github.com/skvadrik/re2c/pull/307>`_, thanks to
`Satoshi Yasushima <https://github.com/s-yasu>`_).
- Fixed bugs in rare cases of the end-of-input rule ``$`` usage
(`277f0295 <https://github.com/skvadrik/re2c/commit/277f0295fc77a2dad3b9838e45f787319b54a25f>`_,
`68611a57 <https://github.com/skvadrik/re2c/commit/68611a57a9683c05801255b35ba6217b91391dd8>`_
and `a9d582f9 <https://github.com/skvadrik/re2c/commit/a9d582f9d2a6d123aa55f3b8b73076aae7cb5616>`_).
- Optimized ``--skeleton`` generation time.
- Renamed internal option ``--dfa`` to ``--nested-negative-tags``.
- Updated documentation for end of input handling and submatch extraction.
----
2.0x
----
2.0.3 (2020-08-22)
~~~~~~~~~~~~~~~~~~
- Fix issues when building re2c as a CMake subproject
(`#302 <https://github.com/skvadrik/re2c/pull/302>`_:
Using CMake add_subdirectory fails)
- 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:
