Hi,
I'm happy to announce the next major release of the antlr4ng TypeScript
runtime, which has been greatly improved.
This release completes the conversion of the Java (and JavaScript)
ANTRL4 runtime to TypeScript. It's a significant improvement over the
existing TS (and JS) runtimes, as it includes now all relevant parts
from the Java runtime and has been optimised for performance. It's now
twice as fast for cold runs and 20% faster with a warm parser/lexer.
Except for small tests where the JS runtime still shines by a very small
margin, this one is faster than any other tested TypeScript and
JavaScript runtime (antlr4, antlr4ts and antlr4wasm). See the original
times taken before the optimisation and the comparison with the other
runtimes

) and compare that to the latest numbers in the antlr4ng repo
(https://urldefense.com/v3/__https://github.com/mike-lischke/antlr4ng/__;!!DeIc-uvKXH9G!49vQ1b1lSRAw85TBvD51UyIrsxtzHFwzA0gYnLonuC656zKZ2Mo9ZkmJVsLr1VVFW9v2h2TzqUCqJHdtBlxlpzywdEAfrKZh96QG$
).
Beside the speed improvements there are a number of API changes (hence
the new major version), which require some adjustments in your code when
you upgrade to this release. If you see problems with it don't hesitate
to open an issue in the repo
(https://urldefense.com/v3/__https://github.com/mike-lischke/antlr4ng/issues__;!!DeIc-uvKXH9G!49vQ1b1lSRAw85TBvD51UyIrsxtzHFwzA0gYnLonuC656zKZ2Mo9ZkmJVsLr1VVFW9v2h2TzqUCqJHdtBlxlpzywdEAfrK6pBD0z$
). The new release is available as NPM package too
(https://urldefense.com/v3/__https://www.npmjs.com/package/antlr4ng__;!!DeIc-uvKXH9G!49vQ1b1lSRAw85TBvD51UyIrsxtzHFwzA0gYnLonuC656zKZ2Mo9ZkmJVsLr1VVFW9v2h2TzqUCqJHdtBlxlpzywdEAfrHG53aAq$
).
Regards,
Mike
