Full Changelog: aviator-5.3.3...aviator-5.4.1

AviatorScript 5.3.3

Main changes:

• Fixed memory leak in lambda function caching #494 #481
• Fixed wrong value captured by function #496
• Adds seq.add_all(seq1, seq2) to add all elements of seq2 to seq1. #500

AviatorScript 5.3.2

Several bugs fixed：

• #466 constant folding do not work when operator is overrided
• #484 Stackoverflow in ArrayUtils
• #483 A corner case in parser.
• #476 Expression#getVariableFullNames() returns the class names when the script has a new statement.

Thank you for all these bug reports.

It's recommended to upgrade.

AviatorScript 5.3.1

Main changes:

• Adds new method AviatorEvaluatorInstance.aliasOperator(OperatorType, String) to set an alias token for logical && and || operator, read the doc.
• Improve [] index operator and seq functions performance when processing arrays.
• Fixed #431 Expression#getVariableNames returns wrong result in nested scope.
• Fixed AviatorEvaluator.execute(String, Map) not work with global caching.

主要改动：

1. 增加 AviatorEvaluatorInstance.aliasOperator(OperatorType, String) 方法用于给 && 和 || 逻辑运算符定义别名，比如定义成 and 或者 or，参见文档
2. 改进对数组的访问性能。
3. 修复 #431 ， Expression#getVariableNames 在处理嵌套范围的时候返回错误结果
4. 修复 AviatorEvaluator.execute(String, Map) 方法不支持全局缓存的 bug

AviatorScript 5.3.0

Release 5.3.0 officially, main changes:

• Supports interpreter mode, you can use aviatorscript on android(or other not-standard JVM) right now. See InterpreterExample and doc. #403 #334 #29
• Fixed assign and define operator can't work when enable TRACE_EVAL. #408
• Implements ApplicationContextAware for SpringContextFunctionLoader. Now SpringContextFunctionLoader can be managed by spring container.

AviatorScript 5.2.7

Main changes:

• Fixed a concurrent issue in Expression#getVariableNames and Expression#getVariableFullNames.
• Should throw no such property exception if property not found when using variable a.b.c dot syntax.

AviatorScript 5.2.6

A strongly recommended upgrading version if you are using 5.x versions.

Main changes:

• Fixed:
  • Anonymous function can't support variadic arguments.
  • continue statement not work with if/else or nested if statements #394
  • LambdaFunction ThreadLocal caching may leak environment context #392
• New features:
  • New function: partial(f, &args) that takes a function f and fewer than the normal arguments to f, and returns a fn that takes a variable number of additional args. When called, the returned function calls f with args + additional args.
  • Use soft reference for caching reflection result #386
  • Added key info to exception message when sequence is null in seq.get function.

[Deprecated] AviatorScript 5.2.5

Main changes:

• Auto convert java boxing types into aviator number types when invoking java methods #369
• Adds a calcuator example which evaluate arithmetic expression in string.
• Bug fixes: can't call overload getter/setter by reflection #368
• Used array-based hashmap for internal env to reduce memory consumption.

[Deprecated] AviatorScript 5.2.4

New features:

• Define anonymous function by fn syntax (instead of lambda ... -> ... end), let add = fn(x, y) { x + y); add(1, 2) for example.
• Unpacking arguments(as sequence) by *args syntax like python, for example:

fn test(a, b, c, d) {
  a * b + c * d
}
let a = tuple(1, 2);
let list = seq.list(3, 4);
p(test(*a, *list));

• Adds AVIATOR_DEPS environment variable to point third-party jar files directory for aviator shell command-line, default is $HOME/.aviatorscript/deps , all jar files under this directory will be added to JVM CLASSPATH .
• Improve for statement, supports index( List/Array sequence etc.) and key/value(Map) iterating:

let a = tuple(1, 2, 3, 4, 5, 6, 7, 8, 9);
for i, x in a {
  assert(i + 1 == x);
}
let m = seq.map("a", 1, "b", 2, "c", 3);
for k, v in m {
    if k == "a" {
      assert(v == 1);
    }elsif k == 'b' {
      assert(v == 2);
    }elsif k == 'c' {
      assert(v == 3);
    }else {
      throw "should not happen";
    }
}

• seq.array_of(Class, dimension1, dimension2, ...dimensions) to create a multidimensional array.
• New functions to add/retrieve/remove object's metadata:

let a = 1;
## retrieve meta ,null if not found
p(meta(a)); 

## associate key/value metadata to any objects by with_meta(obj, key, value)
a = with_meta(a, "key", tuple(1, 2, 3));
p(meta(a));  ## {"key" => [1, 2, 3]}
p(meta(a, "key")); ## [1, 2, 3]

## remove metadata by without_meta(obj, key)
a = without_meta(a, "key");
p(meta(a));  

• Bugs fixed:
  • Wrong size number of Range .
  • JUnit dependency issue, Thanks to DQinYuan

Change log details.
