Release Notes

rust-bakery/nom (nom)

`v8.0.0`

Compare Source

This version represents a significant refactoring of nom to reduce the amount of code generated by parsers, and reduce the API surface. As such, it comes with some breaking changes, mostly around the move from closure based combinators to trait based ones. In practice, it means that instead of writing combinator(arg)(input), we now write combinator(arg).parse(input).

This release also marks the introduction of the nom-language crate, which will hold tools more focused on language parsing than the rest of nom, like the VerboseError type and the newly added precedence parsing combinators.

Thanks

Added

Parser::map_res
Parser::map_opt
many and fold combinators using ranges
many can collect into other types than Vec
Error and VerboseError can be converted to owned versions

Removed

nom::bits::* is no longer re-exported at the crate root. This export caused frequent confusion, since e.g. nom::complete::tag referred to nom::bits::complete::tag instead of the much more commonly used nom::bytes::complete::tag. To migrate, change any imports of nom::{complete::*, streaming::*, bits, bytes} to nom::bits::[...].
parse combinator
InputIter, InputTakeAtPosition, InputLength, InputTake and Slice are now merged in the Input trait

Changed

Parser::map and Parser::flat_map now take a FnMut as argument

`v7.1.3`

Compare Source

`v7.1.2`

Compare Source

Thanks

Changed

documentation fixes
tests fixes
limit the initial capacity of the result vector of many_m_n to 64kiB
bits parser now accept Parser implementors instead of only functions

Added

implement Tuple parsing for the unit type as a special case
implement ErrorConvert on the unit type to make it usable as error type for bits parsers
bool parser for bits input

`v7.1.1`

Compare Source

Thanks

Changed

documentation fixes
more examples

`v7.1.0`

Compare Source

Thanks

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

`v7.0.0`

Compare Source

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

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
