Module flags 

Clap flatten structs for shared flags. Shared clap flatten structs.

Structs

-n/--dry-run with --preview as the visible alias.

One warning. Display is the stderr line after {bin}: warning: .

FormatArgs

-f/--format and -q/--quiet without -c.

FormatLong

--format and -q/--quiet without -f, for CLIs that already use -f for a domain flag such as --file.

OutputArgs

Global pretty/JSON output, color, quiet. Flatten onto the root parser.

Enums

WarningKind

How two (or more) flags fight.

Traits

EnvPrefix

Binds each long option of a Command and of every subcommand to <PREFIX>_<LONG>, so the environment can set any flag a CLI declares.

Functions

chassis_warnings

Chassis flags known to ctl-core.

emit_warnings

Print {bin}: warning: … for each finding.

env_under_flags

Removes each variable that the command line overrules, so the command line wins, and refuses two variables that conflict.

resolve_color

--no-color wins over a --color value.

switch

Last-wins boolean after clap overrides_with. on is the yes flag.

warn_opposites

--foo / --no-foo both present.
