* This change updates `ParseCallbacks::generated_name_override` to accept a second parameter indicating the kind of item the name applies to (currently, either `Function` or `Var`).
* A `CallbackItemKind` enum was added to serve as the type for this second parameter.
* Tests have been updated to verify that the names of both function and variable can be updated by this callback.

Fixes #2008.
Example:
```c
enum Enum { Variant };
typedef int16_t Enum;
```
This is valid and idiomatic C (though not valid C++). `cbindgen` uses this idiom as the default C translation of Rust enums, the equivalent of what would be `enum Enum : int16_t { Variant };` in C++.
`bindgen header.h` before:
```rust
pub const Enum_Variant: Enum = 0;
pub type Enum = ::std::os::raw::c_uint;
pub type Enum = i16;
```
```console
error[E0428]: the name `Enum` is defined multiple times
--> generated.rs:3:1
|
2 | pub type Enum = ::std::os::raw::c_uint;
| --------------------------------------- previous definition of the type `Enum` here
3 | pub type Enum = i16;
| ^^^^^^^^^^^^^^^^^^^^ `Enum` redefined here
|
= note: `Enum` must be defined only once in the type namespace of this module
```
After:
```rust
pub const Enum_Variant: Enum = 0;
pub type Enum = i16;
```

This reverts commit e8ffb42ab66405ac56d04494a30e54b584f2d4dd and adds a new `--wrap-unsafe-ops` option as a workaround.
|
|
This method can be used to process comments and replace them with whatever the user wants.
|
|
This PR introduces a new non-exhaustive `struct` called `DeriveInfo` to be used as the sole argument of `ParseCallbacks::add_derives` with the purpose of being able to extend the information passed to this method in a backwards-compatible manner, meaning that adding new fields to `DeriveInfo` won't be a breaking change when releasing a new version.

Even though this change does name deduplication in a slower way, it
avoids name collisions without any breaking changes in the test suite.
Fixes #2202

Given that C keeps a different namespace for `struct`/`enum`/`union` and `typedef` aliases. The
following patterns
```c
typedef const struct foo {
void *inner;
} *foo;
typedef struct bar {
void *inner;
} *bar;
```
are valid C code and produces both a `struct` and a pointer called `foo`
and `bar` in different namespaces. Given that Rust does not make this
distinction, we add the `_ptr` prefix to the pointer type aliases to
avoid any name collisions.

This fixes #2325.
The issue is that `__bf16` is not exposed at all by libclang, which
causes us to crash. It's a bit of a shame libclang doesn't expose it but
there's no rust equivalent I think, so this should be ok for now.
Unfortunately no test because the header crashes older clang versions.

This guarantees that bindings generated by `bindgen` compile even if the `unsafe_op_in_unsafe_fn` lint is denied.
|
|
* Clean the implementation of `Default` for `BindgenOptions`
|
|
* Add support for the `"C-unwind"` ABI
This allows using `"C-unwind"` as an ABI override if the rust target is
nightly.
|
|
* Add the `--override-abi` option.
This option can be used from the CLI with the <abi>:<regex> syntax and
it overrides the ABI of a function if it matches <regex>.
Fixes #2257
|
|
* Allow callback composition
Store all the callbacks added to the builder in a `Vec` so bindgen
invokes each one of them in a last-to-first manner.
|
|
|
|
* Run `Bindings::generate` again if required.
This adds a mechanism so `bindgen` is able to run `Bindings::generate`
multiple times with the same user input if the `generate_static_inline`
option is enabled and `GenerateResult::ShouldRestart` is returned by
`Bindings::generate`.
This is done to eventually solve #1090 which would require to check for
any static inline functions and generate a new header file to be used as
an extra input and run `Bindings::generate` again.
|
|
* tests: Avoid using globs as regexes
* Sanitize regex set input to properly handle alternation
* Add test case for alternates/anchors interaction
* emit warning if wildcard pattern is used
* update changelog and bump versions

Travis-CI was fully removed as of faf8b3edbaeb591315fc6f370c1228b8caf9860f.
The only badge now [mentioned in the Cargo book][1] is `maintenance`. The
`travis-ci` badge reference was [removed from Cargo two years ago][2]. The
Cargo book advises putting badges in README.md instead.

In Clang 16, anonymous items may return names like
`(anonymous union at ..)` rather than empty names.
The right way to detect them is using clang_Cursor_isAnonymous.

Closes #2316

One of the advantages of doing this is that `ParseCallbacks` no longer
needs to implement `UnwindSafe` which means that users can rely on
`RefCell` and `Cell` to extract information from the callbacks.
Users relying on `catch_unwind` can still achieve similar behavior using
`std::thread::spawn`.
Fixes #2147.

The allowed casts are because c_longlong etc aren't guaranteed to map to
i64 / etc. I believe c_double maps to f64 in all platforms tho.

This adds a new special case for constants like:
```c
extern const char some_static_string[];
```
so `bindgen` emits a `static` instead of a `static mut` for them.

|
Implement `Clone` for `Builder`
|
|
Make postprocessing more robust
|
|
This is done by moving all the remaining `Builder` state into
`BindgenOptions` so any internal logic that affects `Builder` state only
runs once the builder is consumed by `Builder::generate`:
- move `input_headers` to `BindgenOptions`.
- move `input_header_contents` to `BindgenOptions`.
- derive `Clone` for `Builder`.
|
|
This is done by merging extern blocks and sorting items in every module
instead of just in the root module.
The tests were changed to use `cxx` namespaces so they effectively check
that items are manipulated correctly in every single module.

versions, and experiment with new ones.
It's a pity that we don't support clang 3.7 and similar for generating C
bindings, when it should be straight-forward.
This should allow us to support older clang versions, and also experiment with
pre-release clang APIs if needed.
This depends on: https://github.com/KyleMayes/clang-sys/pull/44
