| # `list` Function |
| |
| The `list` function is no longer available. Prior to Terraform v0.12 it was |
| the only available syntax for writing a literal list inside an expression, |
| but Terraform v0.12 introduced a new first-class syntax. |
| |
| To update an expression like `list(a, b, c)`, write the following instead: |
| |
| ``` |
| tolist([a, b, c]) |
| ``` |
| |
| The `[ ... ]` brackets construct a tuple value, and then the `tolist` function |
| then converts it to a list. For more information on the value types in the |
| Terraform language, see [Type Constraints](/terraform/language/expressions/types). |
