This part of nom was not great and a bit of a hack, +so this will give better options for those parsers. + +At last, documentation! There are now more code examples, functions and macros that require +specific cargo features are now clearly indicated, and there's a new `recipes` module +containing example patterns. + +### Breaking changes + +- the minimal Rust version is now 1.44 (1.37 if building without the `alloc` or `std` features) +- streaming parsers return the number of additional bytes they need, not the total. This was supposed to be the case everywhere, but some parsers were forgotten +- removed the `regexp_macros` cargo feature +- the `context` combinator is not linked to `ParseError` anymore, instead it come with its own `ContextError` trait +- `Needed::Size` now contains a `NonZeroUsize`, so we can reduce the structure's size by 8 bytes. When upgrading, `Needed::Size(number)` can be replaced with `Needed::new(number)` +- there is now a more general `Parser` trait, so parsers can be something else than a function. This trait also comes with combinator methods like `map`, `flat_map`, `or`. Since it is implemented on `Fn*` traits, it should not affect existing code too much +- combinators that returned a `impl Fn` now return a `impl FnMut` to allow parser closures that capture some mutable value from the context +- `separated_list` is now `separated_list0` +- removed the deprecated `methods` module +- removed the deprecated `whitespace` module +- the default error type is now a struct (`nom::error::Error`) instead of a tuple +- the `FromExternalError` allows wrapping the error returned by the function in the `map_res` combinator +- renamed the `dbg!` macro to avoid conflicts with `std::dbg!` +- `separated_list` now allows empty elements + + +### Added + +- function version of regex parsers +- `fill`: attempts to fill the output slice passed as argument +- `success`: returns a value without consuming the input +- `satisfy`: checks a predicate over the next character +- `eof` function combinator +- `consumed`: returns the produced value and the consumed input +- `length_count` function combinator +- `into`: converts a parser's output and error values if `From` implementations are available +- `IResult::finish()`: converts a parser's result to `Result<(I, O), E>` by removing the distinction between `Error` and `Failure` and panicking on `Incomplete` +- non macro versions of `u16`, `i32`, etc, with configurable endianness +- `is_newline` function +- `std::error::Error` implementation for nom's error types +- recipes section of the documentation, outlining common patterns in nom +- custom errors example +- bitstream parsing with the `BitSlice` type from the bitvec crate +- native endianness parsers +- github actions for CI + +### Changed + +- allows lexical-core 0.7 +- number parsers are now generic over the input type +- stabilized the `alloc` feature +- `convert_error` accepts a type that derefs to `&str` +- the JSON example now follows the spec better + +### Fixed +- use `fold_many0c` in the `fold_many0` macro + +## 5.1.1 - 2020-02-24 + +### Thanks + +- @Alexhuszagh for float fixes +- @AlexanderEkdahl, @JoshOrndorff, @akitsu-sanae for docs fixes +- @ignatenkobrain: dependency update +- @derekdreery: `map` implementation for errors +- @Lucretiel for docs fixes and compilation fixes +- adytzu2007: warning fixes +- @lo48576: error management fixes + +### Fixed + +- C symbols compilation errors due to old lexical-core version + +### Added + +- `Err` now has a `map` function + +### Changed + +- Make `error::context()` available without `alloc` feature + +## 5.1.0 - 2020-01-07 + +### Thanks + +- @Hywan, @nickmooney, @jplatte, @ngortheone, @ejmg, @SirWindfield, @demurgos, @spazm, @nyarly, @guedou, @adamnemecek, for docs fixes +- @Alxandr for error management bugfixes +- @Lucretiel for example fixes and optimizations +- @adytzu2007 for optimizations +- @audunhalland for utf8 fixes + +### Fixed + +- panic in `convert_error` +- `compile_error` macro usage + +### Added + +- `std::error::Error`, `std::fmt::Display`, `Eq`, `ToOwned` implementations for errors +- inline attribute for `ToUsize` + +### Changed + +- `convert_error` optimization +- `alt` optimization + +## 5.0.1 - 2019-08-22 + +### Thanks + +- @waywardmonkeys, @phaazon, @dalance for docs fixes +- @kali for `many0_m_n` fixes +- @ia0 for macros fixes + +### Fixed + +- `many0_m_n` now supports the n=1 case +- relaxed trait requirements in `cut` +- `peek!` macro reimplementation +- type inference in `value!` + +## 5.0.0 - 2019-06-24 + +This version comes with a complete rewrite of nom internals to use functions as a base +for parsers, instead of macros. Macros have been updated to use functions under +the hood, so that most existing parsers will work directly or require minimal changes. + +The `CompleteByteSlice` and `CompleteStr` input types were removed. To get different +behaviour related to streaming or complete input, there are different versions of some +parsers in different submodules, like `nom::character::streaming::alpha0` and +`nom::character::complete::alpha0`. + +The `verbose-errors` feature is gone, now the error type is decided through a generic +bound.

The previous versions +were focused on `&[u8]` and bit streams parsing, but there's a need for more text +parsing with nom.

It indicates that all child parsers will take a `(&[u8], usize)`as input, with the second parameter indicating the bit offset in the first byte. This allows viewing a byte slice as a bit stream. Most combinators can be used directly under `bits!` +- `take_bits!` takes an integer type and a number of bits, consumes that number of bits and updates the offset, possibly by crossing byte boundaries +- bit level parsers are all written in `src/bits.rs` + +### Changed + +- Parsers that specifically handle bytes have been moved to src/bytes.rs`. This applies to `tag!`, `is_not!`, `is_a!`, `filter!`, `take!`, `take_str!`, `take_until_and_consume!`, `take_until!`, `take_until_either_and_consume!`, `take_until_either!` + +## 0.3.9 - 2015-07-20 + +### Thanks +- @badboy for fixing `filter!` +- @idmit for some documentation fixes + +### Added +- `opt_res!` applies a parser and transform its result in a Result.

The macro has a variant with a third argument indicating the expected input size for the second parser +- benchmarks are available at https://github.com/Geal/nom_benchmarks +- more documentation +- **Unnamed parser syntax**: warning, this is a breaking change. With this new syntax, the macro combinators do not generate functions anymore, they create blocks. That way, they can be nested, for better readability. The `named!` macro is provided to create functions from parsers. Please be aware that nesting parsers comes with a small cost of compilation time, negligible in most cases, but can quickly get to the minutes scale if not careful. If this happens, separate your parsers in multiple subfunctions. +- `named!`, `closure!` and `call!` macros used to support the unnamed syntax +- `map!`, `map_opt!` and `map_res!` to combine a parser with a normal function, transforming the input directly, or returning an `Option` or `Result` + +### Fixed +- `is_a!` is now working properly + +### Removed +- the `o!` macro does less than `chain!`, so it has been removed +- the `fold0!` and `fold1!` macros were too complex and awkward to use, the `many*` combinators will be useful for most uses for now + +## 0.1.6 - 2015-02-24 +### Changed +- consumers must have an end method that will be called after parsing + +### Added +- big endian unsigned int and float parsers: be_u8, be_u16, be_u32, be_u64, be_f32, be_f64 +- producers can seek +- function and macros documentation +- README documentation +### Fixed +- lifetime declarations +- tag!
