+# Changelog
+
+# 6.0.2
+
+> Mar 23, 2023
+
+- Switch to `nom-7`.
+
+# 6.0.1
+
+> Jul 11, 2021
+
+- Better scheme for parenthesis generation in the GLSL transpiler.
+- Fix matrices types in the GLSL transpiler.
+- Fix end-of-line parser, which now accepts CR LF too.
+
+# 6.0
+
+> Dec 7th, 2020
+
+- Change the meaning of `Visitor` and `Host`. They now take the AST nodes by simple references (`&`) and not via
+  mutable references (`&mut`) anymore. This will allow people to use visitors in much more contexts.
+- Add `VisitorMut` and `HostMut` to visit AST nodes mutably. These correspond to the previous (version `<6.0`) `Visitor`
+  and `Host` traits. If you were using them and require mutability, feel free to simply switch to `VisitorMut` and
+  `HostMut`.
+
+# 5.0.2
+
+> Nov 1st, 2020
+
+- Bump `nom-6.0`.
+
+# 5.0.1
+
+> Aug 12th, 2020
+
+- Fix float / double literal parsing priority. Floats are parsed first now in case of a polymorphic
+  constant.
+
+# 5.0.0
+
+> Jul 27th, 2020
+
+- Fix array specifiers by splitting the `ArraySpecifier` type into two types:
+  - `ArraySpecifier`, which holds a non-empty list of `ArraySpecifierDimension`.
+  - `ArraySpecifierDimension`, which is the “old” `ArraySpecifier`.
+  This change allows for multidimensional array specifiers.
+
+## Migration guide
+
+- If you were using array specifiers, you need to wrap them inside an `ArraySpecifierDimension`
+  and wrap it in a `ArraySpecifier { dimensions: NonEmpty(vec![here]) }` expression, where `here`
+  is your specifier.
+
+# 4.1.1
+
+> Wed Jul 1st 2020
+
+- Fix the _identifier_ parser, that previously failed to parse identifiers starting with an
+  underscore (`_`) while it is permitted (chapter 3.7 of the GLSLang spec).
+- Fix associativity for logical binary operators (`||`, `&&`).
+
+# 4.1
+
+> Fri Jun 19th 2020
+
+- Implement `std::error::Error` for error types.
+
+# 4.0.3
+
+> Fri Mar 6th 2020
+
+- Move all the unit tests code into their ow module to prevent rustc from parsing them if we
+  don’t build with tests.
+
+# 4.0.2
+
+> Mon 10th Feb 2020
+
+- Remove the `lexical` feature from `nom`. It’s useful only when using functions such as the
+  `float` combinator, which we don’t use.
+
+# 4.0.1
+
+> Tue 21st Jan 2020
+
+- Fix a bug occurring in the function-like `#define` parser (i.e. `#define foo(x) (y)`) that
+  would prevent the use of whitespaces in the argument list.
+
+# 4.0
+
+> Mon 6th Jan 2020
+
+## Major changes
+
+- Add support for `attribute` and `varying` keyword as a backward-compatible parser.
+- Fix binary operator associativity. They were (_erroneously_) right-associative. They’re now
+  parsed as left-associative.
+
+# 3.0
+
+> Wed 14th Nov 2019
+
+## Major changes
+
+- `JumpStatement::Return` now takes an optional `Expr` instead of an `Expr` directly. That allows
+  for parsing statements such as `return;`, which should have
+  been supported from the beginning.
+- Support for missing preprocessor directives:
+  - `#if`.
+  - `#ifdef`.
+  - `#ifndef`.
+  - `#elseif`.
+  - `#else`.
+  - `#endif`.
+  - `#error`.
+  - `#include`.
+  - `#line`.
+  - `#pragma`.
+  - `#undef`.
+
+## Patch changes
+
+- Add a `rustfmt.toml` to reformat everything and stay consistent. If you want contribute, ensure
+  you are correctly using `rustfmt` (either by running `cargo fmt` before submitting a PR or by
+  configuring your editor to format the code for you). This is important, as not respecting the
+  formatting would make your contribution impossible to merge due to a CI check.
+- Support for _multiline_ annotations (`\`). Multiline annotations are currently supported as
+  part of _spaces_ — i.e. you cannot use them to break an identifier on two lines for instance.
+  This choice makes it faster to parse without too much compromises (after all, `\` is mostly used
+  in CPP directives in GLSL).
+- Fix a bug with _recoverable parsers_ that would produce parent parsers to ignore GLSL grammar
+  errors. That fix also implies a boost in performance due to short-circuiting optimizations.
+
+# 2.0.1
+
+> Fri 8th Nov 2019
+
+- Improve performance of expression parsers.
+
+# 2.0
+
+> Thu 24th Oct 2019
+
+## Major changes
+
+- Add `ShaderKind::Compute`.
+- Remove `NonEmpty::from_iter` and `TranslationUnit::from_iter` as they were deprecated. Use
+  `*::from_non_empty_iter` instead.
+
+## Patch changes
+
+- Fix tokenizer of `Block`.
+- Fix a bug while parsing floating-point numbers.
+- Reformat with `rustfmt`.
+
+# 1.2
+
+> Wed 18th Sep 2019
+
+## Deprecations
+
+- `NonEmpty::from_iter` and `TranslationUnit::from_iter` are deprecated in favor of
+  `*::from_non_empty_iter`.
+
+## Minor changes
+
+- Add binary SPIR-V transpilation. That enables to transpile GLSL directly into a SPIR-V buffer.
+- Add `NonEmpty::from_non_empty_iter` and `TranslationUnit::from_non_empty_iter`.
+
+# 1.1.1
+
+> Tue 17th Sep 2019
+
+- Update internal code for Rust edition 2018.
+
+# 1.1
+
+> Tue 30th of July 2019
+
+- Add the `ShaderStage` type alias to `TranslationUnit`.
+- Enhance the front documentation to showcase how to use how to use the crate.
+
+# 1.0.2
+
+> Tue 23rd of July 2019
+
+- Change the description of the project and update documentation.
+
+# 1.0.1
+
+> Tue 23rd of July 2019
+
+- Change the `external_declaration` parser so that it can also accept _GLSL460_. That should be a
+  breaking change because now, _GLSL450_ formatted input accepts feature from _GLSL460_, which
+  shouldn’t be allowed. Nevertheless, the added feature (being able to use semicolons (`;`) on
+  empty lines at top-level) is not really an interesting property and no breakage should happen.
+
+# 1.0
+
+> Thu 18th of July 2019
+
+- Migrate all parsers to [nom-5](https://crates.io/crates/nom/5.0.0).
+- Improve and add unit and integration tests.
+- Improve overall documentation.
+- Enhance some allocation scheme (removed them by using more adapted parsers).
+- Completely remove the byte (`&[u8]`) parsing. That was a bad idea, for both its impractical
+  aspect and error removing. Parsing is done on string slices now (`&str`).
+
+# 0.13.5
+
+> Sun 9th of December 2018
+
+- Add the SPIR-V transpiler. Currently, it’s feature-gated and *very* experimental. Feel free to
+  try and provide feedback about it.
+- Add simple accessors for `ParseResult`.
+- Fix a typo in the documentation of syntax.
+- Add some unit and integration tests.
+- Add `Identifier::as_str` and `TypeName::as_str`
+
+# 0.13.4
+
+> Wed 25nd of November 2018
+
+- Add `NonEmpty::push` and `NonEmpty::pop`.
+- Implement `Deref` and `DerefMut` for `TranslationUnit`.
+
+# 0.13.3
+
+> Wed 24nd of November 2018
+
+- Add `NonEmpty::from_iter` and `TranslationUnit::from_iter`.
+- Implement `IntoIterator` for `NonEmpty` and `TranslationUnit`.
+
+# 0.13.2
+
+> Wed 22nd of November 2018
+
+- Fix a typo in documentation.
+
+# 0.13.1
+
+> Wed 22nd of November 2018
+
+- Fix a link in documentation.
+
+# 0.13
+
+> Wed 21st of November 2018
+
+- Update/reset hyperlinks in all the documentation for types, traits, methods, etc.
+- General enhancement of the documentation.
+- `ExternalDeclaration::new_struct` can now fail. Check the doc for further details.
+- `NonEmpty`, `Identifier` and `TypeName` and `TranslationUnit` are now plain types and not
+  aliases anymore.
+- Add AST visitors. Visitors allow for traversing through an AST and on-the-fly mutation,
+  filtering, etc.
+- The `#define` preprocessor pragma is now supported in a limited form (it can only be used in
+  the global scope).
+
+# 0.12
+
+> Sun 11th of November 2018
+
+- Fix the type of identifier stored in `Block`: it now uses the new encoding for arrayed
+  identifiers.
+- `Block` parsers update for the arrayd identifier change.
+
+# 0.11
+
+> Sat 10th of November 2018
+
+- Add helper functions to build objects form the `syntax` module. Those are intended to be a
+  simple way to build ASTs out of Rust code instead of parsing.
+- Enhance the documentation of the `Preprocessor` type.
+
+# 0.10.1
+
+> Fri 2nd of November 2018
+
+- Add some missing implementors of `Parse` for types from `glsl::syntax`.
+
+# 0.10
+
+> Fri 2nd of November 2018
+
+- Hide the `parsers` module. It’s not exposed anymore as it was mostly
+  [nom](https://crates.io/crates/nom) parsers and we don’t like leaking internals.
+- Introduce the `Parser` trait, acting as an abstraction over the internal parsers. Implementors
+  provide a type-driven parsing experience that is very similar to the one as
+  [FromStr](https://doc.rust-lang.org/std/str/trait.FromStr.html). This change is actually
+  mandatory for the [glsl-quasiquote](https://crates.io/crates/glsl-quasiquote) crate’s `glsl!`
+  proc-macro to allow people use it for any GLSL item (and not only `TranslationUnit`).
+- Enhance the overall documentation.
+
+# 0.9.2
+
+> Wed 3rd of October 2018
+
+ - Fix GLSL transpiled representation of `IVec*`. It was plain wrong.
+
+# 0.9.1
+
+> Sat 7th of July 2018
+
+- Fix unit testing in transpilers.
+
+# 0.9
+
+> Sat 7th of July 2018
+
+- Big cleanup of the module hierarchy.
+- Enhanced the documentation.
+
+# 0.8.1
+
+> Sun, 17th of June 2018
+
+- Add the `README.md` path to the `Cargo.toml` manifest.
+
+# 0.8
+
+> Sun 17th of June 2018
+
+This version introduces breaking changes because public types used in return positions have changed.
+These concern only intermediate `nom` functions, so if you do not make a fancy use of this crate,
+you souldn’t have to worry too much when migrating.
+
+- Fix the roundtrip issue with the GLSL writer (precedence wasn’t correctly respected).
+- Simplify internal code.
+- Error instead of panicking when parsing overflowing integer literals.
+- Fix panic trying to parse literals starting with whitespace.
+- Add fuzzing to find out panics.
+
+# 0.7.2
+
+> Wed 13th of December 2017
+
+- Fix the `show_expr` when the `Expr` is a `Expr::UIntConst`.
+
+# 0.7.1
+
+> Mon 20th of November 2017
+
+- `std::error::Error` is now implemented for `ParseError`.
+
+# 0.7
+
+> Wed 27th of September 2017
+
+- Add support for postfix expressions as function identifiers.
+
+# 0.6.5
+
+> Mon 4th of September 2017
+
+- Fix the formatting of floating values when the fractional part is `0`.
+
+# 0.6.4
+
+> Mon 4th of September 2017
+
+- Fix the output for `show_struct_specifier`.
+
+# 0.6.3
+
+> Mon 4th of September 2017
+
+- Fix the output for `show_struct_specifier`.
+
+# 0.6.2
+
+> Mon 4th of September 2017
+
+- Remove a warning.
+
+# 0.6.1
+
+> Mon 4th of September 2017
+
+- Fix `show_struct_specifier`.
+
+# 0.6
+
+> Fri 1st of September 2017
+
+- The `TypeSpecifier` type was wrong as it didn’t carry any `ArraySpecifier` information while the
+  GLSL specification’s grammar about type specifiers states they should. Fixed.
+
+# 0.5
+
+> Mon 7th of August 2017
+
+- The `parse` and `parse_str` functions now take as second argument the parser to run. This enables
+  using those functions and all the neat logic the wrap in dependent projects.
+
+# 0.4.2
+
+> Fri 4th of August 2017
+
+- A GLSL writer is now available.
+- Some parsers yield non-empty list of syntax trees. Those had the incorrect `Vec` type. They were
+  replaced by `NonEmpty`, which is an alias to `Vec`, but carry the semantic that it has at least
+  one element in it.
+
+# 0.4.1
+
+> Thu 3rd of August 2017
+
+- Uni/multi-line comments are now supported.
+
+# 0.4
+
+> Wed 2nd of August 2017
+
+- The `Declaration::Block` variant was refactored for a better usage.
+- Dot field selections and, in a mory general way, postfix expressions completely fixed. The
+  `syntax` module was altered to make it easier to work with dot field selection. Also related,
+  the function identifier syntax is now isomorphic to an identifier.
+
+# 0.3.1
+
+> Tue 1st of August 2017
+
+- Fix the `preprocessor` parser so that it eats surrounding blanks.
+
+# 0.3
+
+> Mon 31st of July 2017
+
+- Add a very minimalistic yet working preprocessor. It parses `#version` and `#extension`
+  commands. Those have to be declared at the top of your file, even though this implementation
+  accepts them at any place an external declaration could be defined. Feel free to submit a PR
+  if you want to change that behavior, I don’t really mind.
+- Enhance the runtime error reporting. It’s not perfect, but it’s way better than before!
+- `void` is now recognized as `TypeSpecifier::Void` instead of the erroneous
+  `TypeSpecifier::TypeName("void")`.
+
+# 0.2.2
+
+> Mon 31st of July 2017
+
+- The `layout` parser had a nasty bug that would treat a list of key-value pairs as an expression
+  assignment. This was fixed and it now treats it as a list of pairs of identifier associated with a
+  possible constant expression.
+- The `StructFieldSpecifier` type and its associated parser were wrong. Was missing:
+  + the type qualifier
+  + for each identifier defined in the field specifier, its optional array specifier, as in
+    `float foo[3];` or `vec3 bar[];` for unsized ones.
+
+# 0.2.1
+
+> Sun 30th of July 2017
+
+- More documentation to help people to get their feet wet.
+
+# 0.2
+
+> Sat 29th of July 2017
+
+- The whole parsing API is public.
+
+# 0.1
+
+- Initial revision.
