It was initially part of [SICL][] but has been extracted and\nthe missing required features completed.\n\n# Requirements\n\n[ABCL][], [Clasp][], [ECL][], and [SBCL][] is the only current\nimplementations that this system has been tested on. \n\nIn addition to a clone of this repository in a location that is\ndiscoverable by ASDF you will also need a clone of\n[nontrivial-gray-streams][], [Incless][] and [Inravina][].\n\n# Usage\n\nThe core functionality is in the `invistra` package, but the Common\nLisp-like interface of `format` and `formmatter` is in the\n`invistra-extrinsic` package and system. To call format try\nthe following in SBCL:\n\n```\n* (asdf:load-system :invistra-extrinsic)\nT\n* (invistra-extrinsic:format t \"Wibble: ~a~%\"\n                             :quux)\nWibble: QUUX\nNIL\n```\n\nInvistra can also replace an implementation's FORMAT\nimplementation. This is done with the `invistra-shim` system.\n\n```\n* (asdf:load-system :invistra-shim)\nT\n* (format t \"Wibble: ~a~%\" :quux)\nWibble: QUUX\nNIL\n```\n\n[ABCL]: https://armedbear.common-lisp.dev/\n[CLASP]: https://github.com/clasp-developers/clasp\n[ECL]: https://ecl.common-lisp.dev/\n[Incless]: https://github.com/s-expressionists/Incless\n[Inravina]: https://github.com/s-expressionists/Inravina\n[SBCL]: http://sbcl.org\n[SICL]: https://github.com/robert-strandh/SICL\n[nontrivial-gray-streams]: https://github.com/yitzchak/nontrivial-gray-streams\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fs-expressionists%2Finvistra","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fs-expressionists%2Finvistra","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fs-expressionists%2Finvistra/lists"}
