It should not be used to do real work, but it aspires to be fun and educational.\n\n[Java Virtual Machine]: https://en.wikipedia.org/wiki/Java_virtual_machine\n[tenyr assembly]: https://github.com/kulp/tenyr/wiki/Assembly-language\n[tenyr]: https://github.com/kulp/tenyr\n\n## Status\n\nThe capability envelope is defined by the [test suite], which demonstrates both Java-language capabilities (like [static blocks] or [switches]) and algorithms (like [GCD] or a [sieve of Eratosthenes]).\n\nMany capabilities of the JVM remain unimplemented, including basic things like memory allocation (although [references to allocation][allocation] can be translated).\n\n[test suite]: https://github.com/kulp/tyrga/tree/develop/test\n[static blocks]: https://github.com/kulp/tyrga/blob/develop/test/Static.java\n[switches]: https://github.com/kulp/tyrga/blob/develop/test/Switch.java\n[GCD]: https://github.com/kulp/tyrga/blob/develop/test/GCD.java\n[sieve of Eratosthenes]: https://github.com/kulp/tyrga/blob/develop/test/Sieve.java\n[allocation]: https://github.com/kulp/tyrga/blob/develop/test/Allocate.java\n\n## Basic Usage\n\nThe `tyrga-cli` binary drives the `tyrga-lib` library. The main entry point is `tyrga-cli translate`, which takes Java 11-compatible `.class` files on input and produces `.tas` output files.\n\n    javac --release 11 -g:none test/Sieve.java\n    tyrga-cli translate --output test/Sieve.tas test/Sieve.class\n\nCompare [`Sieve.java`](https://github.com/kulp/tyrga/blob/develop/test/Sieve.java) and [`Sieve.tas`](https://github.com/kulp/tyrga/blob/develop/test/Sieve.tas).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkulp%2Ftyrga","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fkulp%2Ftyrga","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkulp%2Ftyrga/lists"}
