The front-end is actua two possibly interchangeable parsers (from two different projects): ▪ 🚫‹C11-FrontEnd›: 🌐‹https://hackage.haskell.org/package/language-c› ▪ 🌐‹https://gitlri.lri.fr/ftuong/isabelle_c/tree/C/C18-FrontEnd›: 🌐‹https://github.com/jhjourdan/C11parser› present, the recommended and default version is C11. section ‹Getting started› text ‹ A first installation step is: ▪ ▩‹isabelle build -D› 🚫‹.› › text ‹ which should work out of the box. › text ‹ The following C examples or entry-points of documentation can be executed: ▪ ▩‹isabelle jedit -d› 🚫‹.› 🚫‹C11-FrontEnd/examples/C0.thy› ▪ ▩‹isabelle jedit -d› 🚫‹.› 🚫‹C11-FrontEnd/examples/C2.thy› ▪ ▩‹isabelle jedit -d› 🚫‹.› 🚫‹C11-FrontEnd/examples/C1.thy› ▪ ▩‹isabelle jedit -d› 🚫‹.› 🚫‹C11-FrontEnd/appendices/C_Appendices.thy› › text ‹ ▪ The example 🚫‹C11-FrontEnd/examples/C0.thy› is basically used to the faithfulness of the C11 parser implementation. ▪ The example 🚫‹C11-FrontEnd/examples/C2.thy› shows common cases of C and editing support in PIDE; it also contains annotation commands without any seman ▪ The example 🚫‹C11-FrontEnd/examples/C1.thy› is a show-case for markup and the use of bindings resulting from the static C environment. ▪ The example 🚫‹C11-FrontEnd/appendices/C_Appendices.thy› shows the use of /C documentation facilities. text ‹ AFP version of Isabelle/C does not include semantic back-ends (these are distri submissions or available via the web; see below). The structure of 🚫‹.› has designed to create a directory ‹C11-BackEnds› into which back-ends can be . The structure of 🚫‹.› is actually similar as 🌐‹https://gitlri.lri.fr/ftuong/isabelle_c›: see for example 🌐‹https://gitlri.lri.fr/ftuong/isabelle_c/tree/C/C11-BackEnds› where several -ends can be copied and tried. subsection ‹Isabelle/C/README› text ‹ 🚫‹README.md› is automatically generated from 🚫‹README.thy› 🌐‹https://gitlri.lri.fr/ftuong/isabelle_c/blob/C/README.sh›. › text ‹ Note that this shell-script requires the prior installation of ▩‹pandoc› (🌐‹https://github.com/jgm/pandoc›). › section ‹Authors› text ‹ ▪ Frédéric Tuong (🌐‹https://www.lri.fr/~ftuong›) ▪ Burkhart Wolff (🌐‹https://www.lri.fr/~wolff›) › section ‹License› text ‹ /C is licensed under a 3-clause BSD-style license (where certain files are in th compatible with the 3-clause BSD). more details: ▪ The generated files 🚫‹C11-FrontEnd/generated/c_ast.ML› and 🚫‹C11-FrontEnd/generated/c_grammar_fun.grm› are mixing several source code of different projects: ▪ In 3-clause BSD: the part representing the Haskell Language.C library. ▪ In 2-clause BSD: the C99 AST in HOL (before reflection to SML) adapted from th one in the L4.verified project. ▪ In 3-clause BSD: the HOL translation C11 to C99 from the Securify project. ▪ In 3-clause BSD: any other binding and translations of meta-models from the Ci project. ▪ In 3-clause BSD: the two combined generators generating 🚫‹C11-FrontEnd/generated/c_ast.ML› based on some modified version of Haskabelle and Citadelle. ▪ In 3-clause BSD: the Happy modified generator generating 🚫‹C11-FrontEnd/generated/c_grammar_fun.grm› ▪ In HPND: the ML-Yacc modified generator generating the two 🚫‹C11-FrontEnd/generated/c_grammar_fun.grm.sig› and 🚫‹C11-FrontEnd/generated/c_grammar_fun.grm.sml› (i.e., the ML-Yacc version of MLton). ▪ In HPND: the modified grammar library of ML-Yacc loaded in 🚫‹C11-FrontEnd/src/C_Parser_Language.thy›. ▪ In 3-clause BSD: the remaining files in 🚫‹C11-FrontEnd/src› constituting Isabelle/C core implementation. \<^item> Most examples in \<^dir>\<open>C11-FrontEnd/examples\<close> are in 3-clause BSD, some ar used for quotation purposes to test the Isabelle/C lexer (hyperlinks around each example deta their provenance). \<close> end
