Enum yash_syntax::syntax::SwitchCondition

source · [−]

pub enum SwitchCondition {
    Unset,
    UnsetOrEmpty,
}

Expand description

Condition that triggers a switch.

In the lexical grammar of the shell language, a switch condition is an optional colon that precedes a switch type.

Variants

`Unset`

Without a colon, the switch is triggered if the parameter is unset.

`UnsetOrEmpty`

With a colon, the switch is triggered if the parameter is unset or empty.
