It consists of a core calculus with effect\nhandlers and explicit casts, and its metatheory.  This development is\nwritten in Literate Agda; it can be read as a PDF document `doc.pdf`\nincluded in the archive, which also illustrates the proof of gradual\nguarantee with simulation diagrams.\n\nThis development was authored by\n\n   [Li-yao Xia](https://poisson.chat/)\n   [Philip Wadler](https://homepages.inf.ed.ac.uk/wadler/)\n\nas part of the Huawei SAGE project at the University of Edinburgh.\nIt is based on code originally written by\n\n   [Jeremy Siek](https://wphomes.soic.indiana.edu/jsiek/),\n   [Peter Thiemann](http://www2.informatik.uni-freiburg.de/~thiemann/),\n   and\n   [Philip Wadler](https://homepages.inf.ed.ac.uk/wadler/).\n\n[Link to the code repository](http://github.com/Lysxia/gradual-eff-paper)\n\n\nBuild\n-----\n\nThe definitions and proofs can be checked with the following command (it takes a couple of minutes):\n\n```\nmake check\n```\n\nThe PDF document can be (re)compiled with:\n\n```\nmake doc\n```\n\nThe main dependencies are (latest versions as of May 2023):\n\n- Agda 2.6.3\n- [standard-library 1.7.2](https://github.com/Agda/agda-stdlib)\n- pandoc 2.19.2\n- Python\n- [pandoc-latex-environment](https://github.com/chdemko/pandoc-latex-environment)\n\nContents\n--------\n\n- the syntax of types and the imprecision relation (`Types.lagda.md`)\n- the syntax of terms (intrinsically typed) (`Core.lagda.md`)\n- an operational semantics, and an evaluator, which doubles as a proof of progress (`Progress.lagda.md`)\n- the imprecision relation between terms (`Prec.lagda.md`)\n- the proof of the gradual guarantee, as a simulation proof (`SimAux.lagda.md`, `Sim.lagda.md`)\n- some example terms (`Example.lagda.md`, made more readable using an auxiliary module `Sugar.lagda.md`)\n- general-purpose definitions (`Utils.lagda.md`, `VecPointwise2.lagda.md`)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flysxia%2Fgradual-eff-paper","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flysxia%2Fgradual-eff-paper","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flysxia%2Fgradual-eff-paper/lists"}
