String default values parsed from .fbs schemas are un-escaped by the IDL
parser (e.g., \x22 becomes a raw " byte), but code generators embed these
raw values directly into generated source code string literals. This allows
specially crafted .fbs files to break out of string literals and inject
arbitrary code into generated C++, Rust, TypeScript, and Swift source.
Fix by adding EscapeCodeGenString() helper that re-escapes string content
before embedding, and applying it to all 7 affected injection points across
5 code generators (C++, Rust, TypeScript, Swift, FBS).
Resolves the TODO comments in idl_gen_cpp.cpp and idl_gen_rust.cpp.
* Add --ts-undefined-for-optionals command line option
# Details
- Fixes#7656

* chore(idl): Check for case insensitive keywords
Most languages are not affected by this change. In PHP, some names such
as Bool cannot be used because it is a reserved keyword for to the bool
data type. The field `keywords_casing` in the configs enables checking
all characters in lowercase against every keyword. This should be safe
as flatbuffers does not allow non-ASCII characters in its grammar.
* chore: Fix formatting to follow google's coding style for enums
* chore: Extract convert case to lower when CaseInsensitive

Fixes an issue where exports were using incorrect relative paths for
>=3 namespace levels. This is fixed by making the starting range of the
namespace components relative to the amount of components.

* TS/JS: Export object based classes on entry
Along with the non object ones, for consistency. This is a regression
introduced recently.
Before:
`export { UpdateSettingsRequest } from './worker/update-settings-request.js';`
Now:
`export { UpdateSettingsRequest, UpdateSettingsRequestT } from './worker/update-settings-request.js';`
* only export object based classes for structs
Enums are not elegible.

Unfortunately, we lose typing information because the new esbuild method
of generating single files does not generate type information.
The method used here is a bit hack-ish because it relies on parsing the
console output of flatc to figure out what to do.

#7451 caused getFullyQualifiedName to return a name with underscores,
not periods. Because the fully qualified name is a property of
FlatBuffers, not the language being codegen'd for, it should use
periods. Fixes#7564.

+/-inf were not being handled, and so invalid typescript was being
generated when a float/double had an infinite default value. NaN was

* [TS] Add support for fixed length arrays on Typescript (#5864) (#7021)
* Typescript / Javascript don't have fixed arrays but it is important to support these languages for compatibility.
* Generated TS code checks the length of the given array and do truncating / padding to conform to the schema.
* Supports the both standard API and Object Based API.
* Added a test.

The logic to manage generating typescript in a single file was
generating self imports and unused local names, which triggered some

The headline here is adding a flatbuffer_ts_library rule for generating
typescript code in bazel. This entails some non-trivial other changes,
but ideally none are user-visible.
In particular:
* Added a --ts-flat-file flag that generates a single *_generated.ts
file instead of separate files for each typescript type. This makes
bazel much happier.
* Import the bazel rules_nodejs stuff needed to support building
typescript in bazel
* Move flatbuffers.ts to index.ts because I wasn't sure how to make
bazel comprehend the "main" attribute of the package.json. Happy
to take another stab at figuring that out if really needed.
* Fix another couple keyword escaping spots in typescript...
