As we do not appear to have access to a good DTD validation library in
Node.js, we will instead convert the DTD to a JSON schema file and use
that for validation.
I have not verified every aspect of the JSON schema at this point, but
will incrementally do so as I implement further aspects of the compiler.
This updates all the testing to use the schema. As the schema validation
is slow, I have increased the 'normal' time for tests.
Generates a valid .kmx file (legacy structures only) from an
intermediate in-memory structure. Included for completeness, although it
is anticipated that LDML keyboards will not have any groups, though they
will probably have some metadata stores.
Defines kmx binary structures and wireframe builder to emit a .kmx file.
Currently the builder will emit a roughly correct header. Next steps are
to build a .kmx file with stores, groups and keys, to match existing KMX
compiler behaviour. Once that is done, will return to generation of
KMXPlus data structures.
Compiler is designed to work independent of file system so it should run
inside browser or node environment. kmldmlc.ts is node-specific, but all
other modules should be multi-platform.
