Development version

  • Support for Clang/LLVM 16.0.x and 17.0.x

  • #5, #6: fix printing of elaborated declarations in function parameters (reported by rsaill, #5)

  • New function Clang.get_compiler_predefined_macros runs compiler front-end to get the list of predefined macros. They can be passed to compiler command-line with Clang.Command_line.define.

  • New function Clang.get_compiler_include_directories runs compiler front-end to get the list of basic include directories. They can be passed to compiler command-line with Clang.Command_line.include_directory.

  • New function Clang.ext_type_get_field_decl returns the cursor pointing to the field declaration given a type and a field name.

  • New option ignore_no_keyword to suppress NoKeyword elaborated nodes introduced in LLVM 16.

  • Disable clangml.ppx support for now (may be restored if there is use of it).

2022-09-05, 4.8.0

  • Support for Clang/LLVM 15.0.0

  • Ast.character_kind and Ast.string_kind are now distinct types (aliases for Clang.clang_ext_characterkind and Clang.clang_ext_stringkind respectively. The constructor Ordinary replaced the former constructor Ascii for string_kind, to match the new convention used by clang::StringLiteral::StringKind from Clang 15.0.0. The constructor Ascii for character_kind is left unchanged.

  • #1, #2: Ast.Var and Ast.Function constructors now have a storage field in addition to the computed linkage, exposing the value previously accessible via cursor_get_storage_class. The storage classes are now correctly printed by the printer. (reported by Ronan, rsaill/n47, #1)

  • #3, #4: fix Clang.Expr.radix_of_integer_literal when the literal comes from a macro expansion, and fix printing of unsigned/long integer literals with Clang.Printer. (reported by Ronan, rsaill/n47, #3)

2022-08-09, 4.7.0

2022-03-22, 4.6.0

2021-11-11, 4.5.0

  • Support for Clang/LLVM 12.0.1 and 13.0.0.

  • [compatibility break] initializer_list for constructors now contains items with a dedicated type constructor_initializer.

  • Fields for anonymous struct/unions and indirect fields can now be represented in the AST by disabling options.ignore_indirect_fields and options.ignore_anonymous_fields. (reported by Seungwan Kwon)

  • Fields for implicit constructors and methods can now be represented in the AST by disabling options.ignore_implicit_constructors and options.ignore_implicit_methods.

  • Fields for injected class nameds can now be represented in the AST by disabling options.ignore_injected_class_names.

  • Fix segmentation fault issue when accessing NULL TypeInfoLoc* in attributes

2021-02-21, 4.4.0

  • Support for Clang/LLVM 11.0.1, 11.1.0 and 12.0.0.

  • Support for OCaml 4.12.

  • Fix integer overflow on 32-bit platforms.

2020-09-22, 4.3.0

  • Port to ppxlib 0.16 / ocaml-migrate-parsetree 2.0.0

  • Support for Clang/LLVM 11.0.0

  • New module Clang.Cursor, exposing the signature Hashtbl.HashedType with type t = cxcursor and Clang.Cursor.Hashtbl.

  • New function Clang.Decl.annotate_access_specifier, to enumerate class fields with their access specifiers.

  • Fix segmentation fault when parsing the redeclaration of a function decl without prototype when the previous declarations has some parameters. (reported by Kihong Heo)

  • New field has_written_prototype in function_decl to distinguish between function declarations where the prototype is actually provided and declarations where the prototype is inherited.

2020-07-15, 4.2.0

  • Support for Clang/LLVM 10.0.1

C/C++ AST features

  • Support for all C/C++ Clang attributes (including _Alignas (C) and alignas (C++) attributes, that have been requested by Damien Rouhling). See the auto-generated bootstrap/attributes.ml.

  • class base specifiers now expose a full qual_type instead of a mere ident string.

  • ident_ref now carries a template_arguments parameter.

  • function_decl now exposes inline_specified and inlined fields.

  • function_type now exposes ref_qualifier field.

  • TypeLoc are used broaderly to compute qual_type: in particular, parameters in function types have now correct names. The type type_loc and the functions Clang.Decl.get_type_loc and Clang.Parameter.get_type_loc are kept for compatibility, but qual_type should contain all the informations.

API changes

  • Clang.Lazy exposes a lazy AST, that is to say that each desc field is a lazy value that is computed on demand. This is useful to explore large ASTs efficiently (note that Clang parsing itself can still be slow; the lazy part only concerns the conversion into the Clang.Lazy.Ast datatypes). Modules Clang.Ast, Clang.Expr, Clang.Stmt, Clang.Type, ..., have their lazy counter-parts: Clang.Lazy.Ast, Clang.Lazy.Expr, Clang.Lazy.Stmt, Clang.Lazy.Type, etc.

  • The common signature exposed by every AST node module (Clang.Expr, Clang.Stmt, ...) now declares a hash function and and a Hashtbl module.

  • Clang.format_diagnostics now prints presumed locations by default and the behavior can be changed through the optional ?options argument. The implementation now relies on the new Clang.pp_diagnostic which is an OCaml reimplementation of clang_formatDiagnostic from libclang.

  • Clang.Expr.parse_string parses strings as C expressions. (suggested by Damien Rouhling)

  • Clangml_printer has now moved to Clang.Printer. The package clangml.printer still exists for compatibility and reexposes the Clang.Printer interface.

2020-05-15, 4.1.0

  • Compatible with LLVM from 3.4.2 to 10.0.0, OCaml from 4.03.0 to 4.11.0

  • Typeloc structures which contains non-transformed type informations can be obtained with Clang.Decl.get_type_loc and Clang.Parameter.get_type_loc. In particular, typeloc structures can be obtained to get the original size expression from constant arrays. (suggested by Damien Rouhling)

  • Clang.Expr.get_definition and Clang.Decl.get_canonical to retrieve the cursors to the declaration site of identifiers, and Clang.compare_cursors for comparing cursors. (suggested by Arthur Charguéraud)

  • Fix: Constant array sizes are no longer reported as default values for parameters.

  • Fix: Correct representation of integer literal from 32 to 64 bits (reported by Hyunsoo Shin)

  • Relies on metapp, metaquot and refl. All AST types are reflexive in the sense of the refl package. ppxlib and override are not dependencies anymore.

  • clangml.show and clangml.compare packages don't exist anymore. Every AST node module (Clang.Expr, Clang.Stmt, ...) exposes a common signature (Clang.S) with compare, equal, pp and show functions, and Set and Map modules.

  • Access to semantic form for initialization lists (suggested by Hyunsoo Shin)

  • Representation for designated initialization expressions (C99) (suggested by Hyunsoo Shin)

  • Fix: Some distributions such as ArchLinux now gather clang libraries in -lclang-cpp. (reported by Armaël Guéneau)

  • libclang's tokenize and related functions are now accessible, new utility function Clang.Expr.radix_of_integer_literal.

  • Fix: C stub generation used to declare CAMLlocal inside for loops, causing infinite loops in the GC in some occasions. (reported by Armaël Guéneau)

2019-09-30, 4.0.1

  • Support for Clang/LLVM 9.0

  • Compatible with OCaml 4.09

  • Better representation for input and outputs in assembler statements

  • u'c' syntax is now correctly supported with Clang 3.6 and 3.7

  • Support for C++ exception specification, function try block

  • Better support for Gentoo

  • Bug fixes

2019-07-11, 4.0.0

  • C++ support: all the code examples from C++14 and C++17 norms are covered by the AST.

  • AST pretty-printers, comparators and lifters are now defined in sub-libraries (clangml.show, clangml.ord, clangml.lift). Visitors are no longer derived by default (override PPX library can be used to derive visitors from the AST if needed.)

  • A very limited C/C++ pretty-printer is provided in the sub-library clangml.printer. It should be extended in next releases.

  • Compatible with OCaml 4.08

  • Bug fixes

  • Flag dune as a build dependency (suggested by @kit-ty-kate in ocaml/opam-repository#13434)

2019-02-11, 4.0.0beta1

  • First public release
