var

PREREQUISITE: Read bpx-shared.

Usage

bpx var list <file.uasset> bpx var set-default <file.uasset> --name <var> --value '<json>' [--dry-run] [--backup] bpx var rename <file.uasset> --from <old> --to <new> [--dry-run] [--backup]

Behavior

list: merges CDO defaults with declaration metadata.

set-default: writes a variable default on CDO properties.

rename: rewrites matching NameMap entries from --from to --to.

rename fails when destination variable is already declared; may return declaration warnings.

[!CAUTION] This command includes write-capable operations. Confirm intent and run --dry-run first.
