## [7.1.1](https://github.com/ISibboI/evalexpr/compare/7.1.0...7.1.1) - 2022-03-14
|
|
|
|
### Fixed
|
|
|
|
* Set regex minimum version to `1.5.5`, as the previous versions contains a security vulnerability.
|
|
See https://groups.google.com/g/rustlang-security-announcements/c/NcNNL1Jq7Yw?pli=1.
|
|
This vulnerability does not affect this crate as of now, but if we ever allow passing parameters to the regex engine, it might.
|
|
|
|
## [7.1.0](https://github.com/ISibboI/evalexpr/compare/7.0.1...7.1.0) - 2022-03-13
|
|
|
|
### Added
|
|
|
|
* Bit shift functions `shl` and `shr`, same as Rust's shift functions on `i64`.

## [7.0.1](https://github.com/ISibboI/evalexpr/compare/7.0.0...7.0.1) - 2022-02-20
|
|
|
|
### Changed
|
|
|
|
* Updated the optional dependencies, and fixed them to a minimum tested version.
|
|
For simplicity, I fixed them to the newest version, but since I export none of them, this is luckily not breaking.
|
|
* Updated the dev-dependencies.
|
|
|
|
## [7.0.0](https://github.com/ISibboI/evalexpr/compare/6.6.0...7.0.0) - 2022-01-13
|
|
|
|
### Changed
|
|
|
|
* Made the `EvalexprError` enum `non_exhaustive`.
|
|
|
|
### Fixed
|
|
|
|
* Expressions that have dangling parenthese expressions such as `4(5)` now produce an error.

## [5.0.0](https://github.com/ISibboI/evalexpr/compare/4.1.0...5.0.0) - *'Sanity'* - 2019-08-30
|
|
|
|
### Notes
|
|
|
|
Finally, 'Sanity' has been released, including a huge bunch of new features.
|
|
Notably, and providing a reason for the name of this release, function call and tuple semantics have improved a lot.
|
|
Functions now always take exactly one argument, but this can then be a tuple.
|
|
It is now possible to construct tuples of tuples, such that mode complex values can be constructed.
|
|
As of now there is no way to deconstruct them though.
|
|
|
|
A lot has been done on string processing, special thanks for that goes to [bittrance](https://github.com/bittrance).
|
|
Specifically, under the feature flag `regex_support` two regex functions for strings are hiding now.
|
|
Also, the operators `+` and comparison operators have been fitted to support strings.
|
|
|
|
Thanks to [lovasoa](https://github.com/lovasoa), we now have a nice macro for context creation.
|
|
|
|
Thanks to [Atul9](https://github.com/Atul9), the crate is now Rust 2018 compliant.
|
|
|
|
Thanks to [mestachs'](https://github.com/mestachs) request, we now have functions to iterate over identifiers within an expression.
|
|
|
|
Internally, the structure of the operator tree changed from being `&dyn`-based to being `enum`-based.
|
|
Also, we have benchmarks now to observe performance changes in future releases.
|
|
|
|
### Added
|
|
|
|
* Iterator over all identifiers within an expression, including duplicates
|
|
* Iterators over only variable or only function identifiers within an expression, including duplicates
|
|
* Overload the `+` operator to concatenate strings
|
|
* Overload `<`, `<=`, `>` and `>=` for strings using lexical ordering (Note: `==` and `!=` compare strings as expected)
|
|
* Add `len`, `str::regex_matches`, `str::regex_replace`, `str::to_lowercase`, `str::to_uppercase`, `str::trim` functions for strings
|
|
* Add a macro for more convenient definition of contexts including the direct definition of static contexts
|
|
* Add API for value decomposition
|
|
* Allow using context operations in `eval` calls without context
|
|
* Operator assignment operators for each binary operation (`+=`, `-=`, ...)
|
|
* The `Operator` enum is now public for better error types
|
|
* Benchmarks for observing performance of future releases
|
|
|
|
### Removed
|
|
|
|
* Function arguments are not decomposed anymore.
|
|
The function implementation will receive exactly one argument now.
|
|
This allows the function to be called on a tuple properly.
|
|
|
|
### Changed
|
|
|
|
* Operators are an enum now instead of trait objects
|
|
* Update to Rust 2018
|
|
* Updated dependencies
|
|
|
|
### Fixed
|
|
|
|
* Allow variable assignments in eval calls without context.
|
|
A `HashMapContext` is created automatically now.
|
|
* The error string for `ExpectedNumber` was wrong
|
|
* Operators panicked when adding a number to a string
|
|
* Some documentation was not updated for the 4.x releases
|

## [4.1.0](https://github.com/ISibboI/evalexpr/compare/4.0.0...4.1.0) - 2019-03-31
|
|
|
|
### Added
|
|
|
|
* Export `expect_function_argument_amount`
|
|
|
|
## [4.0.0](https://github.com/ISibboI/evalexpr/compare/3.1.0...4.0.0) - 2019-03-30
|
|
|
|
### Added
|
|
|
|
* String constants
|
|
|
|
## [3.1.0](https://github.com/ISibboI/evalexpr/compare/3.0.0...3.1.0) - 2019-03-28
|
|
|
|
### Added
|
|
|
|
* Add serde support to `HashMapContext`
|
|
* Make `HashMapContext` derive `Default` and `Debug`
|
|
|

|
|
## [3.0.0](https://github.com/ISibboI/evalexpr/compare/2.0.0...3.0.0) - 2019-03-28
|
|
|
|
### Notes
|
|
|
|
The 3.0.0 update transforms the expression evaluator `evalexpr` to a tiny scripting language.
|
|
It allows assignments and chaining of expressions.
|
|
Some changes in this update are breaking, hence the major release.
|
|
|
|
### Added
|
|
|
|
* Methods `Node::eval_<type>_with_context_mut` and crate level `eval_<type>_with_context_mut`
|
|
* Empty type and corresponding shortcut methods. The empty type is emitted by empty expressions or empty subexpressions `()`.
|
|
* The assignment operator `=`
|
|
* The expression chaining operator `;`
|
|
|
|
### Removed
|
|
|
|
* Generic arguments from `Context` traits are now static to allow using trait objects of `Context`
|
|
* `EvalexprError::EmptyExpression` is not required anymore since empty expressions now evaluate to the empty type
|
|
|
|
### Changed
|
|
|
|
* Merge `ContextMut` trait into `Context` trait
|
|
|
|
## [2.0.0](https://github.com/ISibboI/evalexpr/compare/1.2.0...2.0.0) - 2019-03-28
|
|
|
|
### Notes
|
|
|
|
The 2.0.0 update is the first step to transform evalexpr to a tiny scripting language with support of at least variable assignment.
|
|
The main change for now is that `Configuration` is called `Context`, which seems to be a more proper naming for a set of variables that can not only be read, but also manipulated via expressions.
|
|
This update includes further renamings and some inconsistencies in the API were fixed.
|
|
For more details, see the following subsections.
|
|
|
|
### Added
|
|
|
|
* Add the `ContextMut` trait, that is a manipulable configuration/context
|
|
* Add `ContextNotManipulable` error variant for the `EmptyContext`
|
|
* Make the `TupleType` alias public
|
|
* Add the `ValueType` enum that represents the type of a value for easier comparisons and matchings
|
|
* Add `EvalexprResult<T>` type that uses the `EvalexprError` type (renamed from `Error`)
|
|
* Add `Node::eval_number` and `Node::eval_number_with_context` to evaluate to int or float and silently converting to float
|
|
* Add `eval_number` and `eval_number_with_context` crate methods to evaluate to int or float and silently converting to float
|
|
|
|
### Changed
|
|
|
|
* Get rid of some unwraps to improve safety
|
|
* Rename `Error` to `EvalexprError`
|
|
* Rename `Configuration` to `Context`
|
|
* Rename `HashMapConfiguration` to `HashMapContext` and `EmptyConfiguration` to `EmptyContext`
|
|
* Rename `Value::as_float` to `Value::as_number` and add new `Value::as_float` that fails if value is an integer
|
|
|
|

|
|
### Added
|
|
|
|
* Internal aliases `IntType` and `FloatType` used by the `Value` enum are now public
|
|
* Type alias `TupleType` used to represent tuples was added
|
|
* Error types like `Error::ExpectedInt` for expecting each value type were added
|

|
|
* Documentation for the shortcut functions was added
|
|
* Functions to decompose `Value`s were added and documented
|
|
|
|
### Removed
|
|
|
|
