First round. I'll go into actual code in the next.

Do we keep the Apple copyright message? Mostly a question for Anne and George.

As per the email discussion, the previously included license as been removed in order to use the existing license in this repository, but these copyright notices should not be disturbed.

Nit: Some comments start with capital letters, some don't. Some have space between # and text and some don't.

I have changed this file to make the comments more consistent in style.

Dumb question - what do we use Java for in this project?

It's dictionary-parser. Denny will likely want to look at that code. It can be reimplemented in another programming language when using wikidata as a data source, but I wanted to provide the tool source code so that the logic behind generating the lexical dictionaries is a lot clearer. The tool will likely be deleted once wikidata can be ingested.

This also had a Java wrapper through JNI. That implementation was excluded from this contribution at this time to expedite making this implementation open source.

Is this just mapping one form of LangID to another? Why (comment)?

It's an aliasing scheme. In this case, we're making the script explicit for a given region.

This has been removed. It was informative about the previous implementation, but it's not helpful anymore.

Do we care how it's generated? If yes, some epointers to the generator would be good.

This is generated with the generateICUWrapper tool. It takes an existing ICU installation, and generates C++ wrappers around the C API. This provides a natural adaptor for C++ API, but with the stability of the C ABI.

The file can be regenerated when ICU adds new C API.

+BreakIterator(UBreakIteratorType type, const char * locale, std::u16string_view text) {
+    UErrorCode ec = U_ZERO_ERROR;
+    wrappee_ = ubrk_open(type, locale, (const UChar *)text.data(), (int32_t)text.size(), &ec);
+    ::morphuntion::exception::ICUException::throwOnFailure(ec);


Some companies don't allow exceptions in code. Do these bubble up to top or are they always caught and then API returns an error?

They're not caught on the C++ API. The C API wrappers around the C++ code converts the exceptions to CFErrorRef. If you don't want C++ exceptions, use the C API. If you want C++ exceptions, use the C++ API. C++ library code also generates exceptions. So you can't completely omit them from C++.

Hopefully this works everywhere we care about (we use guards instead). https://en.wikipedia.org/wiki/Pragma_once

That page doesn't show any compilers that don't support it. I guess the only issue would be if you want to use an old compiler. From a maintenance point of view, this is much more reliable than using macros.

GitHub makes reviewing 800+ files PR a nightmare (everything is super laggy and slow). Let's land this and then go over important details in follow up PRs.
I guess current legal discussion is preventing the merge.

I wonder if, long term, we could convert this into Python or some kind of a template language e.g. https://github.com/kainjow/Mustache

Yes, rewriting this in another programming language is fine. It’s rarely run anyway.
