FYI @WarkahScott authored and committed b47f228, even though it self-attributes to "Googler". I believe future commits will correctly attribute @WarkahScott . |

The main use case we're working toward for shorthand flags is to have them defined in an rcfile and then later used on the command line. Swapping the parsing order allows for the parser to build the full list of known aliases before running into something that looks like an unknown option. For #11750 PiperOrigin-RevId: 327485224

Description of the problem / feature request:
Provide a way to alias Starlark flags so they don't take up so much space on the command line.
Feature requests: what underlying problem are you trying to solve with this feature?
Keep command lines crisp, simple, focused, uncluttered, and clear.
Also, as we migrate native (built into Bazel) flags like
--cputo Starlark flags, we don't want that to bloat command lines.Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.
# Native (built directly into Bazel) flag: $ bazel build //:my_project --cpu=x86# Same-repository Starlark flag: $ bazel build //:my_project --//my/starlark_flags:flag=foo# Different-repository Starlark flag: $ bazel build //:my_project --@some_other_repo//my/starlark_flags:flag=fooHave you found anything relevant by searching the web?
Design document forthcoming.
