ignore

Marks a value to be ignored, causing it to be excluded from branch output. This is useful in conditional branches where you want to discard certain paths.

Syntax

ignore()

Arguments

None.

Examples

Conditionally exclude a value

echo '{"name":"Tom","age":30}' | dasel -i json '(name, if (age > 40) { age } else { ignore() })'

Output:

"Tom"

Since age is not greater than 40, the ignore() branch is taken and only name is output.

Filter branches in a multi-select

(
  name,
  if (has("email")) { email } else { ignore() }
)

This outputs email only if the field exists, without erroring on missing keys.
