The tokens that make up the "key" portion of an index traversal
(e.g. `"foo"` in `a["foo"]`) are structured like those that make up a
block label: an open quote token, a string literal token, and a close
quote token. The token mapper did not account for that fact, and instead
recorded the key token as the open quote. These changes correct that
error, and adjust the code in `literalText` to allow for
properly-escaped and quoted strings where necessary.
- 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
- Parentheses were not handled properly
- Literals inside of template control sequences were not handled
properly
These changes also improve test coverage for the printers.
