0.3.0

Released 2020/06/11

Changed

  • The DemangleOptions API has changed to be more future-proof and the DemangleNodeType enum now has an __NonExhaustive variant to discourage pattern matching without a _ => () arm.

0.2.17

Released 2020/06/09

Added

  • Return types can now be elided from demangled symbols via DemangleOptions::no_return_typ. #202

  • A vtable marker is now emitted for semantic consumers.

0.2.16

Released 2020/05/13

Added

  • Block invocation symbols. #197

  • The spaceship operator <=>. #198

0.2.15

Released 2020/04/24

Added

  • A C API to cpp_demangle is now available. #191

  • Additional AST markers are emitted for semantic consumers. #189

Fixed

  • Multiple clone suffixes are now supported. #194

0.2.14

Released 2019/11/15

Fixed

  • Certain symbols can have cyclic back references, or at least very deep stacks of back references. Many of those symbols are valid! But as a practical implementation to avoid stack overflows and infinite loops, we now place a limit on the depth of back references we will follow. This is similar to the parse limit that we already had, but for a different phase of the demangling. #186

0.2.13

Released 2019/07/30

Fixed

  • Fix parsing of outdated sr forms that prevented parsing other symbols. See #173 for details.

  • Ensures a space is printed before a & or && reference qualifier. #176

  • Fixed placement of parentheses in symbols with function pointer arguments that have const qualifiers. #175

0.2.12

Released 2018/08/09

Fixed

  • Actually fixed builds using no-default-features = true to not accidentally enable no_std mode, which requires nightly rust, and break builds on non-nightly channels. Enabling the no_std mode now requires disabling the std feature and enabling the alloc feature.

0.2.11

Released 2018/08/09

Fixed

  • Fixed builds using no-default-features = true to not accidentally enable no_std mode, which requires nightly rust, and break builds on non-nightly channels. Enabling the no_std mode now requires disabling the std feature and enabling the alloc feature.

0.2.10

Released 2018/08/08

Added

  • Added support for no_std! This currently requires nightly Rust's alloc feature to get access to BTreeMap. Enable no_std support by building without the on-by-default std feature. #148

Fixed

  • Fixed formatting of some conversion operators. #149
  • Fixed parsing some tricky symbols with template argument packs that came out of boost. #150 #152

0.2.9

Released 2018/05/14

Fixed

  • Fixed a few issues with parentheticals.
  • Should not force recompilation via build.rs for every compile anymore (bug introduced in 0.2.8 when trying to make the package that is distributed on crates.io smaller).

0.2.8

Released 2018/05/11

Bug fixes, more libiberty tests passing, and we can now parse and demangle all but one symbol from Firefox's libxul:

Total number of libxul symbols:                       274346
Number of libxul symbols parsed:                      274345 (100.00%)
Number of libxul symbols demangled:                   274345 (100.00%)
Number of libxul symbols demangled same as libiberty: 227259 (82.84%)

Fixed

  • AFL.rs fuzzing integration is fixed for the new AFL.rs releases.
  • Fixed formatting of constructors and destructors.
  • Fixed parsing of the <function-param> production.
  • Fixed parsing of call expression productions.
  • Parsing an operator's operands will only parse as many operands as the operator's arity, instead of as many as it can.

0.2.7

Released 2017/11/27

Making lots of progress on symbols found in the wild! Here are our stats for symbols from Firefox's libxul:

Total number of libxul symbols:                       274346
Number of libxul symbols parsed:                      274319 (99.99%)
Number of libxul symbols demangled:                   274319 (99.99%)
Number of libxul symbols demangled same as libiberty: 199928 (72.88%)

Additionally, the libiberty test threshold bumped up from 70 to 83 during this release.

Added

  • Added support for GCC's "global constructors" and "global destructors" extensions.
  • Added support for GCC's extensions to the <special-name> production: construction vtables, typeinfo functions, TLS initialization functions, TLS wrapper functions.
  • Added support for the now-defunct <local-source-name> production. My understanding is that this is from an older version of the ABI standard. It isn't in the current version, but all the other demanglers support it, so we will too.

Changed

  • cpp_demangle is now part of the gimli-rs GitHub organization. The canonical repository is now https://github.com/gimli-rs/cpp_demangle
  • Literals are now formatted how libiberty formats them. For example, foo<true>() rather than foo<1>().
  • Unary operators are now formatted with parentheses, matching libiberty.

Fixed

  • Nested array types and multi-dimensional arrays are now mangled correctly.
  • Nested function types and their qualifiers are now mangled correctly.
  • Arrays of function types and function types with array return and parameter types are now mangled correctly.
  • The new operator is now correctly formatted as operator new rather than operatornew. Same for the delete operator.

0.2.6

Released 2017/11/08

Added

  • Added support for vector types
  • Added support for ABI tags
  • Added support for <unqualified-name> ::= <closure-type-name> productions

Fixed

  • Fixed erroneous insertions into the substitutions table with prefixes and nested names
  • Well known components were previously incorrectly not permitted to prefix template arguments
