• v0.3.0 Changes

  May 07, 2015

  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!)

• v0.2.2 Changes

  April 12, 2015

  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

• v0.2.1 Changes

  April 04, 2015

  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

  ➕ Added

  • little endian unsigned int parsers le_u8, le_u16, le_u32, le_u64
  • 📜 count! to apply a parser a specified number of times
  • 📜 cond! applies a parser if the condition is met
  • 📜 more parser development tools in util::*

  🛠 Fixed

  • in one case, opt! would not compile

  ✂ Removed

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

• v0.2.0 Changes

  March 24, 2015

  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
  • 0️⃣ 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

• v0.1.6 Changes

  February 24, 2015

  🔄 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! can return Incomplete

• v0.1.5 Changes

  February 17, 2015
