其中.用来访问对象的属性,例如:staff.name、#staff.age;[]用来访问数组、集合的元素,例如:array[0]、#map[key]。理论上,支持任意级嵌套使用,例如:list[0][1].name、#map[key][1].staff.name。1.4.0版本开始支持参数访问符。 参数转换器 参数转换器用于对参数值进行转换,主要应用场景是统一获取用户输入参数...

Now we can look at the DLR AST. In the Visual Studio Locals window, expand the node called block, which is a CodeBlock AST node. This is the root node for the file of Python code. Part of translating a language's specific syntax tree to the DLR's AST is clea...

I have a dynamic array type in C++ that I would like to expose through the buffer protocol. The type is already exposed as a sequence in Python, but I want to build NumPy arrays with the C++ array data, and I am hoping that a buffer will be faster than the element-wise construction...
Preamble Following up on the actionflows issue and how it used global context to provide "dynamic subroutine calls" capabilities. Description Add ability to perform link-call dynamically Update documentation Considerations / questions Sh...
The Lambda editor and Calc.ts should be a pretty good fit. The editor checks syntax but if that is OK why not a form to accept a set of test parameters and display results on a small grid? As for FastExcel it is possible to download a time limited test copy. What I was suggesting...
