2.0 KiB
Version 0.12 (not yet released)
Version 0.11
Updated to use the regex-syntax crate for regular expression
parsing instead of rolling our own parser. This means we can now
support the same regular expression syntax as the regex crate,
and in particular can support unicode character classes like \p{Greek}.
Note that some regex features -- such as non-greedy repetition and
named capture groups -- are still not supported (or just not meaningful).
Optimized LR(1) construction time by approximately 5x.
Improved handling of location tokens @L and @R so that they can be
freely used without ever causing parse conflicts.
Version 0.10
Major update to LALRPOP error messages in cases of shift/reduce and reduce/reduce conflicts. The messages now try to explain the problem in terms of your grammar, as well as diagnosing common problem scenarios and suggesting solutions.
Added a standalone LALRPOP executable.
We no longer generate incomplete files when grammar generation fails (Issue #57).
Version 0.9
Miscellaneous bug fixes, mostly. Processing for a build.rs file now
starts from the project directory, rather than being hardcoded to
start from src.
Version 0.8
Add support for inlining nonterminals. Nonterminals can now be
annotated with #[inline]. If you do so, each use of the nonterminal
will be inlined into its place. This can be very helpful in addressing
shift-reduce or reduce-reduce conflicts, at the cost of a larger
grammar. We now inline Foo*, Foo?, and (Foo Bar) nonterminals by
default.
Version 0.7
This is mostly a bug-fix release.
Various minor issues were addressed:
- Issue #25: Unbalanced parens in string literals appearing in code now work properly.
- Issue #32: Regular expression parsing consumed infinite memory when a
.appeared. - Issue #34: Automatic tokenizer generation did not play well with generic type parameters.

I hadn't yet started writing release notes, sorry.
