section ‹Isabelle/C›
text ‹
Isabelle/C contains a C99/C11/C18 front-end support for Isabelle. The front-end is actually
composed
of 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›
At 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/C1.thy›
▪ ▩‹isabelle jedit -d› ‹.› ‹C11-FrontEnd/examples/C2.thy›
▪ ▩‹isabelle jedit -d› ‹.› ‹C11-FrontEnd/examples/C3.thy›
▪ ▩‹isabelle jedit -d› ‹.› ‹C11-FrontEnd/examples/C4.thy›
▪ ▩‹isabelle jedit -d› ‹.› ‹C11-FrontEnd/C_Appendices.thy›
›
text ‹
▪ The example ‹C11-FrontEnd/examples/C0.thy› is basically used to
demonstrate the faithfulness of the C11 parser implementation.
▪ The example ‹C11-FrontEnd/examples/C1.thy› is a show-case for markup
generation and the use of bindings resulting from the static C environment.
▪ The example ‹C11-FrontEnd/examples/C2.thy› shows common cases of C and
C editing support in PIDE; it also contains annotation commands without any semantics.
▪ The example ‹C11-FrontEnd/C_Appendices.thy› shows the use of
Isabelle/C documentation facilities.
›
text ‹
The AFP version of Isabelle/C does not include semantic back-ends (these are distributed by other
AFP submissions or available via the web; see below). The structure of ‹.› has
been designed to create a directory ‹C11-BackEnds› into which back-ends can be
installed. 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
back-ends can be copied and tried.

subsection ‹Isabelle/C/README›

‹README.md› is automatically generated from ‹README.thy›
using ‹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 ‹License›
text ‹
Isabelle/C is licensed under a 3-clause BSD-style license (where certain files are in the HPND
license compatible with the 3-clause BSD).
In 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 the original
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 Citadelle
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.
▪ Most examples in ‹C11-FrontEnd/examples› are in 3-clause BSD, some are
used for quotation purposes to test the Isabelle/C lexer (hyperlinks around each example detail
their provenance).
