Zaid Ajaj 0d458a47df [program-gen] Fix PCL bind error "cannot iterate over a value of type number" (#17569 ) ### Description Often when converting terraform modules such as tf VPC module, the range expression of resources is a conditional expression of the form `if should_create_resource ? N : 0`. These expressions resolve their type to one of `int`, `bool`, `Output[int]` or `Output[bool]`. Any other type we assume we are dealing with a collection that we are trying to iterate over. However if the conditional expression resolves to `optional(int)` then we think it is a collection, try to get it's key-value pair types and error with "cannot iterate over a value of type number" This PR fixes this problem by unwrapping `int` from `optional(int)` when encountered in these range expressions. I was able to isolate a subset of the converted PCL from terraform VPC module where this problem occurs and created a unit test from it. Interesting note is that this only occurs in _non-strict_ mode 🤔 in strict mode, the expression type from `range` is not optional. I've not been able to find out why that is the case yet.		2024-10-17 20:55:38 +00:00

Code generation

Code generation is essential to Pulumi's ability to support both a variety of programming languages and a variety of cloud providers. This package defines the core components of Pulumi's code generation functionality (known as Pulumi CrossCode). At a high level, code generation is used to manage three categories of output: SDKs, programs, and documentation. At a lower level, these all make use of a number of shared concepts such as schema and Pulumi Configuration Language (PCL).
