Debug Adapter Protocol Support

Back in #​926 (v0.26.0), support was added for the Debug Adapter Protocol (DAP), based on the new OPA SDK added in #​6876 (documentation). This release improves on this making it ready for consumption in clients. Namely, the addition of a new Debug Code Lens in #​1103 and a bug fix for ast.ref_to_string which brings the Regal implementation inline with OPA’s (#​1106).

Please see our documentation here to get started.

Neovim DAP Support

Thanks to community member @​rinx, DAP support is also available in the Neovim editor. This is based on nvim-dap, and @​rinx’s own project nvim-dap-rego. This is an awesome contribution which represents an important improvement for Neovim users of Regal. Thank you Rintaro Okamura for all your work here, it is appreciated.

New Rule: comprehension-term-assignment

This rule flags cases where an intermediate assignment is used within a comprehension body when the value can be directly used as the comprehension term. It enforces the removal of redundant assignments, encouraging more concise and readable code.

### avoid
names := [name |
    some user in input.users
    name := user.name
]

### prefer
names := [user.name | some user in input.users]

Compiler Stage Source Explorer

A new Source Action has been added to allow users of compatible clients to explore the compiler stages of the Rego code they’re working on.

By integrating opa-explorer with Regal, it’s now possible to launch a web server to view the explorer output. Users will see a "Source Action" in the context menu of Rego files, which opens the explorer for that file. This feature is currently limited to VS Code due to available commands. Currently, only a single file is loaded into the explorer for compilation.
