Support for XeLaTeX
Is there a plan to support XeTeX / XeLaTeX in the future as well? I'd also like to help out - if there is some documentation on how other projects are structured in general (for pdftex and luatex), that would help me get started.
As for the how to do it, it’s relatively simple: cross compile to an arm64 binary (using cross-compiling tools), add dependency to ios_system for input, output and file system communication, and make sure memory is released when the command leaves.
For XeTeX, the problem is in the first step: it has a strong dependency on frameworks and libraries that are specific to OS X, and so it cannot be cross-compiled for arm64. Luatex code is much better for cross-compiling.
To the best of my knowledge, luatex abilities are a superset of those of XeTeX (anything XeTeX can do, luatex can also do), so there is little to be gained by adding XeTeX.
