Changed

documentation fixes
Ci fixes
the move to minimal-lexical for float parsing introduced bugs that cannot be resolved right now, so this version moves back to using the standard lib' parser. This is a performance regression*. If you have specific requirements around float parsing, you are strongly encouraged to use recognize_float and another library to convert to a f32 or f64

Added

alt now works with 1 elment tuples

7.0.0 - 2021-08-21

This release fixes dependency compilation issues and strengthen the minimum supported Rust version (MSRV) policy. This is also the first release without the macros that were used since nom's beginning.

Thanks

@homersimpsons
@lo48576
@myrrlyn

@nickelc
@cenodis

Added

take_until1 combinator
more to_owned implementations
fail: a parser that always fail, useful as default condition in other combinators
text to number parsers: in the character::streaming and character::complete modules, there are parsers named i8, u16, u32, u64, u128 and u8 ,u16, u32, u64, u128 that recognize decimal digits and directly convert to a number in the target size (checking for max int size)

Removed

now that function combinators are the main way to write parsers, the old macro combinators are confusing newcomers. THey have been removed
the BitSlice input type from bitvec has been moved into the nom-bitvec crate. nom does not depend on bitvec now
regex parsers have been moved into the nom-regex crate. nom does not depend on regex now
ErrorKind::PArseTo was not needed anymore

Changed

relax trait bounds
some performance fixes
split_at_position* functions should now be guaranteed panic free
the lexical-core crate used for float parsing has now been replaced with minimal-lexical: the new crate is faster to compile, faster to parse, and has no dependencies

Fixed

infinite loop in escaped combinator
many_m_n now fails if min > max

Notable changes

This release is a more polished version of nom 5, that came with a focus on function parsers, by relaxing the requirements: combinators will return a impl FnMut instead of impl Fn, allowing closures that change their context, and parsers can be any type now, as long as they implement the new Parser trait. That parser trait also comes with a few helper methods.

Error management was often a pain point, so a lot of work went into making it easier. Now it integrates with std:error::Error, the IResult::finish() method allows you to convert to a more usable type, the into combinator can convert the error type if there's a From implementation, and there are more specific error traits like ContextError for the context combinator, and FromExternalError for map_res. While the VerboseError type and its convert_error function saw some changes, not many features ill be added to it, instead you are encouraged to build the error type that corresponds to your needs if you are building a language parser.

This version also integrates with the excellent bitvec crate for better bit level parsing. 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

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. To get equivalent behaviour to verbose-errors, check out nom::error::VerboseError

Thanks

Added

the VerboseError type accumulates position info and error codes, and can generate a trace with span information
the lexical-core crate is now used by default (through the lexical compilation feature) to parse floats from text
documentation and code examples for all functions and macros

Changed

nom now uses functions instead of macros to generate parsers
macros now use the functions under the hood
the minimal Rust version is now 1.31
the verify combinator's condition function now takes its argument by reference
cond will now return the error of the parser instead of None
alpha*, digit*, hex_digit*, alphanumeric* now recognize only ASCII characters

Removed

deprecated string parsers (with the _s suffix), the normal version can be used instead
verbose-errors is not needed anymore, now the error type can be decided when writing the parsers, and parsers provided by nom are generic over the error type
AtEof, CompleteByteSlice and CompleteStr are gone, instead some parsers are specialized to work on streaming or complete input, and provided in different modules
character parsers that were aliases to their *1 version: eol, alpha, digit, hex_digit, oct_digit, alphanumeric, space, multispace
count_fixed macro
whitespace::sp can be replaced by character::complete::multispace0
method combinators are now in the nom-methods crate
take_until_either, take_until_either1, take_until_either_and_consume and take_until_either_and_consume1: they can be replaced with is_not (possibly combined with something else)
take_until_and_consume, take_until_and_consume1: they can be replaced with take_until combined with take
sized_buffer and length_bytes!: they can be replaced with the length_data function
non_empty, begin and rest_s function

Changed

macro import in edition 2018 code should work without importing internal macros now
the regex parsers do not require the calling code to have imported the regex crate anymore
error conversions are more ergonomic
method combinators are now deprecated. They might be moved to a separate crate
nom now specifies Rust 1.24.1 as minimum version. This was already the case before, now it is made explicit

Breaking changes

the IResult type now becomes a Result from the standard library
Incomplete now returns the additional data size needed, not the total data size needed
verbose-errors is now a superset of basic errors
all the errors now include the related input slice
the arguments from error_position and other such macros were swapped to be more consistent with the rest of nom
automatic error conversion: to fix error type inference issues, a custom error type must now implement std::convert::From<u32>
the not! combinator returns unit ()
FindToken's calling convention was swapped
the take_* combinators are now more coherent and stricter, see commit 484f6724ea3ccb for more information
many0 and other related parsers will now return Incomplete if the reach the end of input without an error of the child parser. They will also return Incomplete on an empty input
the sep! combinator for whitespace only consumes whitespace in the prefix, while the ws! combinator takes care of consuming the remaining whitespace

Added

the AtEof trait for input type: indicate if we can get more input data later (related to streaming parsers and Incomplete handling)
the escaped* parsers now support the &strinput type
the Failure error variant represents an unrecoverable error, for which alt and other combinators will not try other branches. This error means we got in the right part of the code (like, a prefix was checked correctly), but there was an error in the following parts
the CompleteByteSlice and CompleteStr input types consider there will be no more refill of the input. They fixed the Incomplete related issues when we have all of the data
the exact!() combinator will fail if we did not consume the whole input
the take_while_m_n! combinator will match a specified number of characters
ErrorKind::TakeUntilAndConsume1
the recognize_float parser will match a float number's characters, but will not transform to a f32 or f64
alpha and other basic parsers are now much stricter about partial inputs. We also introduce the *0 and *1 versions of those parsers
named_args can now specify the input type as well
HexDisplay is now implemented for &str
alloc feature
the InputTakeAtposition trait allows specialized implementations of parsers like take_while!

Removed

the producers and consumers were removed
the error_code and error_node macros are not used anymore

Fixed

anychar! now works correctly with multibyte characters
take_until_and_consume1! no longer results in "no method named `find_substring`" and "no method named `slice`" compilation errors
take_until_and_consume1! returns the correct Incomplete(Needed) amount
no_std compiles properly, and nom can work with alloc too
parse_to! now consumes its input

Changed

alt and other combinators will now clone the input if necessary. If the input is already Copy there is no performance impact
the rest parser now works on various input types
InputIter::Item for &[u8] is now a u8 directly, not a reference
we now use the compile_error macro to return a compile time error if there was a syntax issue
the permutation combinator now supports optional child parsers
the float numbers parsers have been refactored to use one common implementation that is nearly 2 times faster than the previous one
the float number parsers now accept more variants

3.2.1 - 2017-10-27

Thanks

@ordian for alt_complete fixes
@friedm for documentation fixes
@kali for improving error management

Fixed

there were cases where alt_complete could return Incomplete

Added

an into_error_kind method can be used to transform any error to a common value. This helps when the library is included multiple times as dependency with different feature sets

3.2.0 - 2017-07-24

Thanks

@jedireza for documentation fixes
@gmorenz for the bytes combinator
@meh for character combinator fixes for UTF-8
@jethrogb for avoiding move issues in separated_list

Changed

new layout for the main page of documentation
anychar can now work on any input type
length_bytes is now an alias for length_data

Fixed

one_of, none_of and char will now index correctly UTF-8 characters
the compiler_error macro is now correctly exported

Added

the bytes combinator transforms a bit stream back to a byte slice for child parsers

3.1.0 - 2017-06-16

Thanks

@sdroege: implementing be_i24 and le_i24
@Hywan: integrating faster substring search using memchr

@doomrobo: implementing separated_list_complete and separated_nonempty_list_complete
@CWood1: fixing memchr integration in no_std
@lu_zero: integrating the compiler_error crate
@dtolnay: helping debug a type inference issue in map

Changed

memchr is used for substring search if possible
if building on nightly, some common syntax errors will display a specific error message. If building no stable, display the documentation to activate those messages
count no longer preallocates its vector

Fixed

better type inference in alt_complete
alt should now work with whitespace parsing
map should not make type inference errors anymore

Added

be_i24 and le_i24, parsing big endian and little endian signed 24 bit integers
separated_list_complete and separated_nonempty_list_complete will treat incomplete from sub parsers as error

3.0.0 - 2017-05-12

Thanks

Chris Pick for some Incomplete related refactors
@dbrgn for documentation fixes

Breaking Changes

escaped, separated_list and separated_nonempty_list can now return Incomplete when necessary
InputIter does not require AsChar on its Item type anymore
the core feature that was putting nom in no_std mode has been removed. There is now a std feature, activated by default. If it is not activated, nom is in no_std
in verbose-errors mode, the error list is now stored in a Vec instead of a box based linked list
chain! has finally been removed

Changed

Endianness now implements Debug, PartialEq, Eq, Clone and Copy
custom input types can now be cloned if they're not Copy
the infamous 'Cannot infer type for E' error should happen less often now

Fixed

FileProducer will be marked as Eof on full buffer
named_args! now has lifetimes that cannot conflict with the lifetimes from other arguments

Added

be_u24: big endian 24 bit unsigned integer parsing
IResult now has a unwrap_or method

2.2.1 - 2017-04-03

Thanks

@Victor-Savu for formatting fixes in the README
@chifflier for detecting and fixing integer overflows
@utkarshkukreti for some performance improvements in benchmarks

Changed

when calculating how much data is needed in IResult::Incomplete, the addition could overflow (it is stored as a usize). This would apparently not result in any security vulnerability on release code

2.2.0 - 2017-03-20

Thanks

@seppo0010 for fixing named_args
@keruspe for implementing or() on IResult, adding the option of default cases in switch!, adding support for cargo-travis

Changed

hex_u32 accepts uppercase digits as well
the character based combinators leverage the input traits
the whitespace parsers now work on &str and other types
take_while1 returns Incomplete on empty input
switch! can now take a default case

Fixed

named_args! now imports IResult directly
the upgrade to regex 0.2 broke the regex combinators, they work now

2.1.0 - 2017-01-27

Thanks

@nickbabcock for documentation fixes
@derekdreery for documentation fixes
@DirkyJerky for documentation fixes
@saschagrunert for documentation fixes
@lucab for documentation fixes
@hyone for documentation fixes
@tstorch for factoring Slice
@shepmaster for adding crate categories
@antoyo for adding named_args!

Added

verify! uses a first parser, then applies a function to check that its result satisfies some conditions
named_args! creates a parser function that can accept other arguments along with the input
parse_to! will use the parse method from FromStr to parse a value. It will automatically translate the input to a string if necessary
float, float_s, double, double_s can recognize floating point numbers in text

Changed

escaped! will now return Incomplete if needed
permutation! supports up to 20 child parsers

2.0.1 - 2016-12-10

Bugfix release

Warning: there is a small breaking change, add_error! is renamed to add_return_error!. This was planned for the 2.0 release but was forgotten. This is a small change in a feature that not many people use, for a release that is not yet widely in use, so there will be no 3.0 release for that change.

Thanks

@nickbabcock for catching and fixing the add_error! mixup
@lucab for documentation fixes
@jtdowney for noticing that tag_no_case! was not working at all for byte slices

Fixed

add_error! has been renamed to add_return_error!
the not! combinator now accepts functions
tag_no_case! is now working as accepted (before, it accepted everything)

2.0 - 2016-11-25

The 2.0 release is one of the biggest yet. It was a good opportunity to clean up some badly named combinators and fix invalid behaviours.

Since this version introduces a few breaking changes, an upgrade documentation is available, detailing the steps to fix the most common migration issues. After testing on a set of 30 crates, most of them will build directly, a large part will just need to activate the "verbose-errors" compilation feature. The remaining fixes are documented.

This version also adds a lot of interesting features, like the permutation combinator or whitespace separated formats support.

Thanks

@lu-zero for license help
@adamgreig for type inference fixes
@keruspe for documentation and example fixes, for the IResult => Result conversion work, making AsChar's method more consistent, and adding many_till!
@jdeeny for implementing Offset on &str
@vickenty for documentation fixes and his refactoring of length_value! and length_bytes!
@overdrivenpotato for refactoring some combinators
@taralx for documentation fixes
@keeperofdakeys for fixing eol behaviour, writing documentation and adding named_attr!
@jturner314 for writing documentation
@bozaro for fixing compilation errors
@uniphil for adding a crates.io badge
@badboy for documentation fixes
@jugglerchris for fixing take_s!
@AndyShiue for implementing Error and Display on ErrorKind and detecting incorrect UTF-8 string indexing

Added

the "simple" error management system does not accumulates errors when backtracking. This is a big perf gain, and is activated by default in nom 2.0
nom can now work on any type that implement the traits defined in src/traits.rs: InputLength, InputIter, InputTake, Compare, FindToken, FindSubstring, Slice
the documentation from Github's wiki has been moved to the doc/ directory. They are markdown files that you can build with cargo-external-doc
whitespace separated format support: with the ws! combinator, you can automatically introduce whitespace parsers between all parsers and combinators
the permutation! combinator applies its child parsers in any order, as long as they all succeed once, and return a tuple of the results
do_parse! is a simpler alternative to chain!, which is now deprecated
you can now transform an IResult in a std::result::Result
length_data! parses a length, and returns a subslice of that length
tag_no_case! provides case independent comparison. It works nicely, without any allocation, for ASCII strings, but for UTF-8 strings, it defaults to an unsatisfying (and incorrect) comparison by lowercasing both strings
named_attr! creates functions like named! but can add attributes like documentation
many_till! applies repeatedly its first child parser until the second succeeds

Changed

the "verbose" error management that was available in previous versions is now activated by the "verbose-errors" compilation feature
code reorganization: most of the parsers were moved in separate files to make the source easier to navigate
most of the combinators are now independent from the input type
the eof function was replaced with the eof! macro
error! and add_error! were replaced with return_error! and add_return_error! to fix the name conflict with the log crate
the offset() method is now in the Offset trait
length_value! has been renamed to length_count!. The new length_value! selects a slice and applies the second parser once on that slice
AsChar::is_0_to_9 is now AsChar::is_dec_digit
the combinators with configurable endianness now take an enum instead of a boolean as parameter

Fixed

the count!, count_fixed! and length_*! combinator calculate incomplete data needs correctly
eol, line_ending and not_line_ending now have a consistent behaviour that works correctly with incomplete data
take_s! didn't correctly handle the case when the slice is exactly the right length

1.2.4 - 2016-07-20

Thanks

@Phlosioneer for documentation fixes
@sourrust for fixing offsets in take_bits!
@ChrisMacNaughton for the XFS crate
@pwoolcoc for rest_s
@fitzgen for more IResult methods
@gtors for the negative lookahead feature
@frk1 and @jeandudey for little endian float parsing
@jethrogb for fixing input usage in many1
@acatton for beating me at nom golf :D

Added

the rest_s method on IResult returns the remaining &str input
unwrap_err and unwrap_inc methods on IResult
not! will peek at the input and return Done if the underlying parser returned Error or Incomplete, without consuming the input
le_f32 and le_f64 parse little endian floating point numbers (IEEE 754)

Fixed

documentation fixes
take_bits! is now more precise
many1 inccorectly used the len function instead of input_len
the INI parser is simpler
recognize! had an early return that is removed now

1.2.3 - 2016-05-10

Thanks

@lu-zero for the contribution guidelines
@GuillaumeGomez for fixes on length_bytes and some documentation
@Hywan for documentation and test fixes
@Xirdus for correct trait import issues
@mspiegel for the new AST example
@cholcombe973 for adding the cond_with_error! combinator
@tstorch for refactoring many0!
@panicbit for the folding combinators
@evestera for separated_list! fixes
@DanielKeep for correcting some enum imports

Added

Regular expression combinators starting with re_bytes_ work on byte slices
example parsing arithmetic expressions to an AST
cond_with_error! works like cond! but will return None if the condition is false, and Some(value) if the underlying parser succeeded
fold_many0!, fold_many1! and fold_many_m_n! will take a parser, an initial value and a combining function, and fold over the successful applications of the parser

Fixed

length_bytes! converts the result of its child parser to usize
take_till! now imports InputLength instead of assuming it's in scope
separated_list! and separated_nonempty_list! will not consume the separator if there's no following successfully parsed value
no more warnings on build

Changed

simpler implementation of many0!

1.2.2 - 2016-03-09

Thanks

@conradev for fixing take_until_s!
@GuillaumeGomez for some documentation fixes
@frewsxcv for some documentation fixes
@tstorch for some test refactorings

Added

nom::Err now implements std::error::Error

Fixed

hex_u32 does not parses more than 8 chars now
take_while! and take_while1! will not perturb the behaviour of recognize! anymore

1.2.1 - 2016-02-23

Thanks

@sourrust for adding methods to IResult
@tstorch for the test refactoring, and for adding methods to IResult and Needed
@joelself for fixing the method system

Added

mapping methods over IResult and Needed

Changed

apply_rf is renamed to apply_m. This will not warrant a major version, since it is part missing from the methods feture added in the 1.2.0 release
the regexp_macros feature that used regex! to precompile regular expressions has been replaced by the normal regex engine combined with lazy_static

Fixed

when a parser or combinator was returning an empty buffer as remaining part, it was generating one from a static empty string. This was messing with buffer offset calculation. Now, that empty slice is taken like this: &input[input.len()..].
The regexp_macros and no_std feature build again and are now tested with Travis CI

1.2.0 - 2016-02-08

Thanks

@zentner-kyle for type inference fixes
@joelself for his work on &str parsing and method parsers
@GuillaumeGomez for implementing methods on IResult
@dirk for the alt_complete! combinator
@tstorch for a lot of refactoring work and unit tests additions
@jansegre for the hex digit parsers
@belgum for some documentation fixes
@lwandrebeck for some documentation fixes and code fixes in hex_digit

Added

take_until_and_consume_s! for consumption of string data until a tag
more function patterns in named!. The error type can now be specified
alt_complete! works like the alt! combinator, but tries the next branch if the current one returned Incomplete, instead of returning directly
more unit tests for a lot of combinators
hexadecimal digit parsers
the tuple! combinator takes a list of parsers as argument, and applies them serially on the input. If all of them are successful, it willr eturn a tuple accumulating all the values. This combinator will (hopefully) replace most uses of chain!
parsers can now be implemented as a method for a struct thanks to the method!, call_m! and apply_rf! combinators

Fixed

there were type inference issues in a few combinators. They will now be easier to compile
peek! compilation with bare functions
&str parsers were splitting data at the byte level, not at the char level, which can result in inconsistencies in parsing UTF-8 characters. They now use character indexes
some method implementations were missing on IResult<I,O,E> (with specified error type instead of implicit)

1.1.0 - 2016-01-01

This release adds a lot of features related to &str parsing. The previous versions were focused on &[u8] and bit streams parsing, but there's a need for more text parsing with nom. The parsing functions like alpha, digit and others will now accept either a &[u8] or a &str, so there is no breaking change on that part.

There are also a few performance improvements and documentation fixes.

Thanks

@Binero for pushing the work on &str parsing
@meh for fixing Option and Vec imports
@hoodie for a documentation fix
@joelself for some documentation fixes
@vberger for his traits magic making nom functions more generic

Added

string related parsers: tag_s!, take_s!, is_a_s!, is_not_s!, take_while_s!, take_while1_s!, take_till_s!
value! is a combinator that always returns the same value. If a child parser is passed as second argument, that value is returned when the child parser succeeds

Changed

tag! will now compare even on partial input. If it expects "abcd" but receives "ef", it will now return an Error instead of Incomplete
many0! and others will preallocate a larger vector to avoid some copies and reallocations
alpha, digit, alphanumeric, space and multispace now accept as input a &[u8] or a &str. Additionally, they return an error if they receive an empty input
take_while!, take_while1!, take_while_s!, take_while1_s! wilreturn an error on empty input

Fixed

if the child parser of many0! or many1! returns Incomplete, it will return Incomplete too, possibly updating the needed size
Option, Some, None and Vec are now used with full path imports

1.0.1 - 2015-11-22

This releases makes the 1.0 version compatible with Rust 1.2 and 1.3

Thanks

@steveklabnik for fixing lifetime issues in Producers and Consumers

1.0.0 - 2015-11-16

Stable release for nom. A lot of new features, a few breaking changes

Thanks

@ahenry for macro fixes
@bluss for fixing documentation
@sourrust for cleaning code and debugging the new streaming utilities
@meh for inline optimizations
@ccmtaylor for fixing function imports
@soro for improvements to the streaming utilities
@breard-r for catching my typos
@nelsonjchen for catching my typos too
@divarvel for hex string parsers
@mrordinaire for the length_bytes! combinator

Breaking changes

IResult::Error can now use custom error types, and is generic over the input type
Producers and consumers have been replaced. The new implementation uses less memory and integrates more with parsers
nom::ErrorCode is now nom::ErrorKind
filter! has been renamed to take_while!
chain! will count how much data is consumed and use that number to calculate how much data is needed if a parser returned Incomplete
alt! returns Incomplete if a child parser returned Incomplete, instead of skipping to the next parser
IResult does not require a lifetime tag anymore, yay!

Added

complete! will return an error if the child parser returned Incomplete
add_error! will wrap an error, but allow backtracking
hex_u32 parser

Fixed

the behaviour around Incomplete is better for most parsers now

0.5.0 - 2015-10-16

This release fixes a few issues and stabilizes the code.

Thanks

@nox for documentation fixes
@daboross for linting fixes
@ahenry for fixing tap! and extending dbg! and dbg_dmp!
@bluss for tracking down and fixing issues with unsafe code
@meh for inlining parser functions
@ccmtaylor for fixing import of str::from_utf8

Fixed

tap!, dbg! and dbg_dmp! now accept function parameters

Changed

the type used in count_fixed! must be Copy
chain! calculates how much data is needed if one of the parsers returns `Incomplete
optional parsers in chain! can return Incomplete

0.4.0 - 2015-09-08

Considering the number of changes since the last release, this version can contain breaking changes, so the version number becomes 0.4.0. A lot of new features and performance improvements!

Thanks

@frewsxcv for documentation fixes
@ngrewe for his work on producers and consumers
@meh for fixes on chain! and for the rest parser
@daboross for refactoring many0! and many1!
@aleksander for the switch! combinator idea
@TechnoMancer for his help with bit level parsing
@sxeraverx for pointing out a bug in is_a!

Fixed

count_fixed! must take an explicit type as argument to generate the fixed-size array
optional parsing behaviour in chain!
count! can take 0 elements
is_a! and is_not! can now consume the whole input

Added

it is now possible to seek to the end of a MemProducer
opt! returns Done(input, None) if the child parser returned Incomplete`
rest will return the remaining input
consumers can now seek to and from the end of input
switch! applies a first parser then matches on its result to choose the next parser
bit-level parsers
character-level parsers
regular expression parsers
implementation of take_till!, take_while! and take_while1!

Changed

alt! can return Incomplete
the error analysis functions will now take references to functions instead of moving them
performance improvements on producers
performance improvement for filter!
performance improvement for count!: a Vec of the right size is directly allocated

0.3.11 - 2015-08-04

Thanks

@bluss for remarking that the crate included random junk lying non committed in my local repository

Fixed

cleanup of my local repository will ship less files in the crates, resulting in a smaller download

0.3.10 - 2015-08-03

Added

bits! for bit level parsing. 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. This parser never fails
cond_reduce! takes an expression as parameter, applies the parser if the expression is true, and returns an error if the expression is false
tap! pass the result of a parser to a block to manipulate it, but do not affect the parser's result
AccReader is a Read+BufRead that supports data accumulation and partial consumption. The consume method must be called afterwardsto indicate how much was consumed
Arithmetic expression evaluation and parsing example
u16!, u32!, u64!, i16!, i32!, i64! take an expression as parameter, if the expression is true, apply the big endian integer parser, if false, the little endian version
type information for combinators. This will make the documentation a bit easier to navigate

Fixed

map_opt! and map_res! had issues with argument order due to bad macros
delimited! did not compile for certain combinations of arguments
filter! did not return a byte slice but a fixed array

0.3.8 - 2015-07-03

Added

code coverage is now calculated automatically on Travis CI
Stepper: wrap a Producer, and call the method step with a parser. This method will buffer data if there is not enough, apply the parser if there is, and keep the rest of the input in memory for the next call
ReadProducer: takes something implementing Read, and makes a Producer out of it

Fixed

the combinators separated_pair! and delimited! did not work because an implementation macro was not exported
if a MemProducer reached its end, it should always return Eof
map! had issues with argument matching

0.3.7 - 2015-06-24

Added

expr_res! and expr_opt! evaluate an expression returning a Result or Opt and convert it to IResult
AsBytes is implemented for fixed size arrays. This allows tag!([41u8, 42u8])

Fixed

count_fixed! argument parsing works again

0.3.6 - 2015-06-15

Added

documentation for a few functions
the consumer trait now requires the failed(&self, error_code) method in case of parsing error
named! now handles the alternative named!(pub fun_name<OutputType>, ...)

Fixed

filter! now returns the whole input if the filter function never returned false
take! casts its argument as usize, so it can accepts any integer type now

0.3.5 - 2015-06-10

Thanks

@cmr for some documentation fixes

Added

count_fixed! returns a fixed array

Fixed

count! is back to the previous behaviour, returning a Vec for sizes known at runtime

Changed

functions and traits exported from nom::util are now directly in nom::

0.3.4 - 2015-06-09

Thanks

@andrew-d for fixes on cond!
@keruspe for features in chain!

Added

chain! can now have mutable fields

Fixed

cond! had an infinite macro recursion

Changed

chain! generates less code now. No apprent compilation time improvement

0.3.3 - 2015-06-09

Thanks

@andrew-d for the little endian signed integer parsers
@keruspe for fixes on count!

Added

le_i8, le_i16, le_i32, le_i64: little endian signed integer parsers

Changed

the alt! parser compiles much faster, even with more than 8 branches
count! can now return a fixed size array instead of a growable vector

0.3.2 - 2015-05-31

Thanks

@keruspe for the take_str parser and the function application combinator

Added

take_str!: takes the specified number of bytes and return a UTF-8 string
apply!: do partial application on the parameters of a function

Changed

Needed::Size now contains a usize instead of a u32

0.3.1 - 2015-05-21

Thanks

@divarvel for the big endian signed integer parsers

Added

be_i8, be_i16, be_i32, be_i64: big endian signed integer parsers
the core feature can be passed to cargo to build with no_std
colored hexdump can be generated from error chains

0.3.0 - 2015-05-07

Thanks

@filipegoncalves for some documentation and the new eof parser
@CrimsonVoid for putting fully qualified types in the macros
@lu_zero for some documentation fixes

Added

new error types that can contain an error code, an input slice, and a list of following errors
error! will cut backtracking and return directly from the parser, with a specified error code
eof parser, successful if there is no more input
specific error codes for the parsers provided by nom

Changed

fully qualified types in macros. A lot of imports are not needed anymore

Removed

FlatMap, FlatpMapOpt and Functor traits (replaced by map!, map_opt! and map_res!)

0.2.2 - 2015-04-12

Thanks

@filipegoncalves and @thehydroimpulse for debugging an infinite loop in many0 and many1
@thehydroimpulse for suggesting public named parsers
@skade for removing the dependency on the collections gate

Added

named! can now declare public functions like this: named!(pub tst, tag!("abcd"));
pair!(X,Y) returns a tuple (x, y)
separated_pair!(X, sep, Y) returns a tuple (x, y)
preceded!(opening, X) returns x
terminated!(X, closing) returns x
delimited(opening, X, closing) returns x
separated_list(sep, X) returns a Vec<X>
separated_nonempty_list(sep, X) returns a Vec<X> of at list one element

Changed

many0! and many1! forbid parsers that do not consume input
is_a!, is_not!, alpha, digit, space, multispace will now return an error if they do not consume at least one byte

0.2.1 - 2015-04-04

Thanks

@mtsr for catching the remaining debug println!
@jag426 who killed a lot of warnings
@skade for removing the dependency on the core feature gate

Fixed

in one case, opt! would not compile

Removed

most of the feature gates are now removed. The only one still needed is collections

0.2.0 - 2015-03-24

works with rustc 1.0.0-dev (81e2396c7 2015-03-19) (built 2015-03-19)

Thanks

Ryman for the AsBytes implementation
jag426 and jaredly for documentation fixes
eternaleye on #rust IRC for his help on the new macro syntax

Changed

the AsBytes trait improves readability, no more b"...", but "..." instead
Incomplete will now hold either Needed;;Unknown, or Needed::Size(u32). Matching on Incomplete without caring for the value is done with Incomplete(_), but if more granularity is mandatory, Needed can be matched too
alt! can pass the result of the parser to a closure
the take_* macros changed behaviour, the default case is now not to consume the separator. The macros have been renamed as follows: take_until! -> take_until_and_consume!, take_until_and_leave! -> take_until!, take_until_either_and_leave! -> take_until_either!, take_until_either! -> take_until_either_and_consume!

Added

peek! macro: matches the future input but does not consume it
length_value! macro: the first argument is a parser returning a n that can cast to usize, then applies the second parser n times. 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
