contains:\n\n+ Development blogs which are written for general audience\n+ [Installation](https://www.aya-prover.org/guide/install.html)\n  instructions (basically telling you what to download in [GitHub Releases])\n+ [Tutorial for functional programming features](https://www.aya-prover.org/guide/haskeller-tutorial.html)\n+ [Tutorial for theorem proving features](https://www.aya-prover.org/guide/prover-tutorial.html)\n\n\u003e [!WARNING]\n\u003e\n\u003e Aya is under active development, so don't be surprised about bugs, usability or performance issues\n\u003e (please file issues or create threads in discussions!), but we have the goal to make it as\n\u003e user-friendly as we can feasibly do.\n\n## What to expect?\n\n+ Dependent types, including Π-types, Σ-types, indexed families, etc.\n  You could write a [sized-vector type][gadt].\n+ Set-level cubical type theory (XTT).\n  + Demonstration of [quotient-inductive-inductive types][hiir],\n    no forward declaration or mutual block needed!\n    We infer the type checking order by how definitions use each other.\n  + Proof of `funExt` in [paths.aya][funExt].\n+ Pattern matching with first-match semantics.\n  Checkout the [red-black tree][rbtree] (without deletion yet).\n+ A JIT-compiler that translates Aya code to higher-order abstract syntax in Java.\n  This makes the interpreter to run tree-sort 10x faster! See [benchmark code][tbtree-bench].\n+ Overlapping and order-independent patterns. Very [useful][oop] in theorem proving.\n+ A literate programming mode with inline code fragment support, inspired from Agda and [1lab].\n  You may preview the features (in Chinese)\n  [here](https://blog.kiva.moe/posts/intro-literate-aya.html).\n+ Binary operators, with precedence specified by a partial ordering\n  (instead of a number like in Haskell or Agda).\n+ A fairly good termination checker.\n  We adapted some code from Agda's implementation to accept more definitions such as the\n  `testSwapAdd` example in [this file][foetus] (which are rejected by, e.g. Arend).\n\nSee also [use as a library](#use-as-a-library).\n\n[GitHub Releases]: https://github.com/aya-prover/aya-dev/releases/tag/nightly-build\n[1lab]: https://1lab.dev\n\n## Contributing to Aya\n\nSee [HACKING.md](HACKING.md) for technical details,\n[CONTRIBUTING.md](CONTRIBUTING.md) for social responsibilities,\nand [CODE_OF_CONDUCT.md](CODE_OF_CONDUCT.md).\n\nQuestions are _always_ welcomed in [Discussion](https://github.com/aya-prover/aya-dev/discussions).\nWe will try our best to answer your questions. Please be nice to us!\nWe also welcome nitpicks on any user-interaction issues, especially on error reporting.\nLet us know if you have any suggestions.\n\n[actions]: https://github.com/aya-prover/aya-dev/actions/workflows/gradle-check.yaml/badge.svg\n[codecov]: https://img.shields.io/codecov/c/github/aya-prover/aya-dev?logo=codecov\u0026logoColor=white\n[maven]: https://img.shields.io/maven-central/v/org.aya-prover/base?logo=gradle\n[oop]: ../cli-impl/src/test/resources/shared/src/arith/nat/base.aya\n[gadt]: ../cli-impl/src/test/resources/shared/src/data/vec/base.aya\n[regularity]: ../cli-impl/src/test/resources/shared/src/paths.aya\n[funExt]: ../cli-impl/src/test/resources/shared/src/paths.aya\n[rbtree]: ../jit-compiler/src/test/resources/TreeSort.aya\n[tbtree-bench]: ../jit-compiler/src/test/java/RedBlackTreeTest.java\n[hiir]: https://www.aya-prover.org/blog/tt-in-tt-qiit.html\n[foetus]: ../cli-impl/src/test/java/org/aya/test/fixtures/TerckError.java\n[maven-repo]: https://repo1.maven.org/maven2/org/aya-prover\n\n## Use as a library\n\nIt's indexed in [mvnrepository](https://mvnrepository.com/artifact/org.aya-prover),\nand here are some example build configurations:\n\n```xml\n\u003c!-- Maven --\u003e\n\u003cdependency\u003e\n    \u003cgroupId\u003eorg.aya-prover\u003c/groupId\u003e\n    \u003cartifactId\u003e[project name]\u003c/artifactId\u003e\n    \u003cversion\u003e[latest version]\u003c/version\u003e\n\u003c/dependency\u003e\n```\n\n```groovy\n// Gradle\nimplementation group: 'org.aya-prover', name: '[project name]', version: '[latest version]'\n```\n\n+ `[project name]` specifies the subproject of Aya you want to use,\n  and the options are `pretty`, `base`, `cli-impl`, `parser`, etc.\n  + For the list of the subprojects, see [HACKING.md](HACKING.md).\n+ `[latest version]` is what you see on this badge ![maven].\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Faya-prover%2Faya-dev","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Faya-prover%2Faya-dev","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Faya-prover%2Faya-dev/lists"}
