v1.2.0

Version 1.2.0 released to crates.io.

Bug fixes with breaking script changes

• As originally intended, function calls with a bang (!) now operates directly on the caller's scope, allowing variables inside the scope to be mutated.
• As originally intended, Engine::XXX_with_scope API's now properly propagate constants within the provided scope also to functions in the script.
• Printing of integral floating-point numbers is fixed (used to only prints 0.0).
• func!() calls now work properly under no_closure.
• Fixed parsing of unary negation such that expressions like if foo { ... } -x parses correctly.

New features

• #[cfg(...)] attributes can now be put directly on plugin functions or function defined in a plugin module.
• A custom syntax parser can now return a symbol starting with $$ to inform the implementation function which syntax variant was actually parsed.
• AST::iter_literal_variables is added to extract all top-level literal constant/variable definitions from a script without running it.
• Engine::call_fn_dynamic is deprecated and Engine::call_fn_raw is added which allows keeping new variables in the custom scope.

Enhancements

• Array methods now avoid cloning as much as possible (although most predicates will involve cloning anyway if passed a closure).
• Array methods that take function pointers (e.g. closures) now optionally take the function name as a string.
• Array adds the dedup method.
• Array adds a sort method with no parameters which sorts homogeneous arrays of built-in comparable types (e.g. INT).
• Inlining is disabled for error-path functions because errors are exceptional and scripts usually fail completely when an error is encountered.
• The optimize module is completely eliminated under no_optimize, which should yield smaller code size.
• NativeCallContext::position is added to return the position of the function call.
• Scope::clone_visible is added that copies only the last instance of each variable, omitting all shadowed variables.

Deprecated API's

• NativeCallContext::call_fn_dynamic_raw is deprecated and NativeCallContext::call_fn_raw is added.
• From<EvalAltResult> for Result<T, Box<EvalAltResult>> is deprecated so it will no longer be possible to do EvalAltResult::ErrorXXXXX.into() to convert to a Result; instead, Err(EvalAltResult:ErrorXXXXX.into()) must be used. Code is clearer if errors are explicitly wrapped in Err.

v1.1.2

This release fixes a number of bugs:

• 0.0 now prints correctly (used to print 0e0).
• Unary operators are now properly recognized as an expression statement.
• The global namespace is now searched before packages, which is the correct behavior.

A regression in string operations via the + operator is also reversed.

v1.1.1

Bug fixes

• Assignment to indexing expression with dot expressions inside no longer cause a compilation error.
• The no_module and internals features now work together without a compilation error.
• String literal operations (such as "hello" + ", world") now optimizes correctly.

v1.1.0

Version 1.1.0 released to crates.io.

Bug fixes

• Custom syntax starting with a disabled standard keyword now works properly.
• When calling Engine::call_fn, new variables defined during evaluation of the body script are removed and no longer spill into the function call.
• NamespaceRef::new is fixed.

Enhancements

Engine API

• Engine::consume_XXX methods are renamed to Engine::run_XXX to make meanings clearer. The consume_XXX API is deprecated.
• Engine::register_type_XXX are now available even under no_object.
• Added Engine::on_parse_token to allow remapping certain tokens during parsing.
• Added Engine::const_empty_string to merge empty strings into a single instance.

Custom Syntax

• $symbol$ is supported in custom syntax to match any symbol.
• Custom syntax with $block$, } or ; as the last symbol are now self-terminating (i.e. no need to attach a terminating ;).

Dynamic Values

• Dynamic::as_string and Dynamic::as_immutable_string are deprecated and replaced by into_string and into_immutable_string respectively.
• Added a number of constants to Dynamic.
• Added a number of constants and fromXXX constant methods to Dynamic.
• Added sin, cos and tan for Decimal values.

Decimal Values

• parse_float(), PI() and E() now defer to Decimal under no_float if decimal is turned on.
• Added log10() for Decimal.
• ln for Decimal is now checked and won't panic.

String Values

• SmartString now uses LazyCompact instead of Compact to minimize allocations.
• Added pop for strings.
• Added ImmutableString::ptr_eq to test if two strings point to the same allocation.
• The serde feature of SmartString is turned on under metadata to make Map serializable.

Scope API

• Scope::set_value now takes anything that implements Into<Cow<str>>.
• Added Scope::is_constant to check if a variable is constant.
• Added Scope::set_or_push to add a new variable only if one doesn't already exist.

AST API

• Added ASTNode::position.
• ReturnType is removed in favor of option flags for Stmt::Return.
• Stmt::Break and Stmt::Continue are merged into Stmt::BreakLoop via an option flag.
• StaticVec is changed to keep three items inline instead of four.

v1.0.6

Bug fixes

• Eliminate unnecessary property write-back when accessed via a getter since property getters are assumed to be pure.
• Writing to a property of an indexed valued obtained via an indexer now works properly by writing back the changed value via an index setter.

Enhancements

• MultiInputsStream, ParseState, TokenIterator, IdentifierBuilder and AccessMode are exported under the internals feature.

v1.0.5

This is a bug fix version with the following fixes:

• FloatWrapper is no longer erroneously exported under no_float+internals.
• The sign function now works properly for float values that are NaN.

v1.0.4

Fixed bug with catch variable used in catch block.

This release fixes a bug in 1.0.3 which has been yanked.

v1.0.2

Fixed bug in method call followed by an array indexing.

v1.0.1

Bug fixes

• Fixed bug in using indexing/dotting inside index bracket.
• while and loop statements are no longer considered pure (since a loop can go on forever and this is a side effect).

v1.0.0

The official version 1.0.

Almost the same version as 0.20.3 but with deprecated API's removed.

Version 1.0.0 released to crates.io.

Bug fixes

• Fixed infinite loop in certain script optimizations.
• Building for no-std no longer requires patching smartstring.
• Parsing a lone return or throw without a semicolon at the end of a block no longer raises an error.

Breaking changes

• All deprecated API's (e.g. the RegisterFn and RegisterResultFn traits) are removed.
• Module::set_id is split into Module::set_id and Module::clear_id pair.
• begin, end, each, then, unless are no longer reserved keywords.

Enhancements

• New methods is_odd, is_even for integers, and is_zero for all numbers.
• From<BTreeSet> and From<HashSet> are added for Dynamic, which create object maps with () values.
