2.0 (2020-07-20)
~~~~~~~~~~~~~~~~
- Added new code generation backend for Go and a new ``re2go`` program

- 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🎏o``, ``re2c🎏output``.
- Changes in ``re2c🎏t``, ``re2c🎏type-header`` configuration:
filename is now relative to the output file directory.
- Added option ``--case-ranges`` and configuration ``re2c🎏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".
