There are two expressions in HCL2 that are used to iterate over
collections:
- Splat expressions, e.g. `foo.*.bar`, and
- For expressions, e.g. `[for v in foo: v.bar]`
In both of these cases, the parts of the expression that are not the
collection being iterated behave like callbacks, and must be treated as
such by the apply rewriter.
Some of the apply rewriter's assumptions were broken by the richer
expressions available in HCL2. These changes fix those broken
assumptions, in particular the assumption that only scope traversal
expressions are sources of eventual values.
- Define `null` in Pulumi HCL2
- Bind Pulumi HCL2 in topological order s.t. variable types can be
properly computed
- Fix resources that range over bools and numbers
- Add element, length, lookup, readFile, and split functions
- Do not rewrite function signatures with input types during binding
- Fix splat expression binding for non-lists
- Add support for evaluating expressions
- Add support for operator precedence to code generators
- Add support for constants to the HCL2 IR
- Add support for generating ranged resources in Python
- Add support for generating conditional resource in Node and Python
- Fix various naming issues in Python
* Make `async:true` the default for `invoke` calls (#3750)
* Switch away from native grpc impl. (#3728)
* Remove usage of the 'deasync' library from @pulumi/pulumi. (#3752)
* Only retry as long as we get unavailable back. Anything else continues. (#3769)
* Handle all errors for now. (#3781)
* Do not assume --yes was present when using pulumi in non-interactive mode (#3793)
* Upgrade all paths for sdk and pkg to v2
* Backport C# invoke classes and other recent gen changes (#4288)
Adjust C# generation
* Replace IDeployment with a sealed class (#4318)
Replace IDeployment with a sealed class
* .NET: default to args subtype rather than Args.Empty (#4320)
* Adding system namespace for Dotnet code gen
This is required for using Obsolute attributes for deprecations

* Fix the nullability of config type properties in C# codegen (#4379)
Pulumi HCL2 IR:
- Add support for invokes
- Add support for resource options, incl. ranged resources
- Allow the apply rewriter to ignore promise-typed values
- Add tests for the binder
- Add support functions for TF: entries and range
NodeJS codegen:
- Simplify for expression codegen
- Add support for invoke codegen
- Add support for entries and range functions
- Add tests
Python codegen:
- Implement codegen for most expression types
- Add support for invoke codegen
- Add tests
- config variables are now specified as `config <name> <type>`
- output variables are now specified as `output <name> <type>`
- apply arguments are assigned better names by the apply rewriters
These changes add preliminary (read: incomplete) support for
representing Pulumi programs using HCL2. Language-specific code
generators can use this representation as a basis for understanding the
semantics of a Pulumi program.
