Usage:
require "clang"
index = Clang::Index.new
files = [
#Clang::UnsavedFile.new("input.c", "#include <pcre.h>\n"),
Clang::UnsavedFile.new("input.c", "#include <clang/Basic/ABI.h>\n"),
]
tu = Clang::TranslationUnit.from_source(index, files, [
"-I/usr/include",
"-I/usr/lib/llvm-5.0/include",
])
tu.cursor.visit_children do |cursor|
p cursor

endSee the samples folder for some example usages:
samples/debug.crwill print the AST of C or C++ headers as they are parsed;samples/c2cr.crwill automatically generate Crystal bindings for a C header.
For example:
$ shards build --release
$ bin/c2cr -I/usr/lib/llvm-5.0/include llvm-c/Core.h \
--remove-enum-prefix=LLVM --remove-enum-suffix > llvm-c/Core.cr
$ bin/c2cr -I/usr/lib/llvm-5.0/include clang-c/Index.h \
--remove-enum-prefix > clang-c/Index.cr
$ bin/c2cr gtk-2.0/gtk/gtkenums.h --remove-enum-prefix > gtk/enums.crDistributed under the Apache 2.0 license.
