Variants

Syntax(String)

A syntax error in a check line.

UndefVariable(String)

A check refers to an undefined variable.

The pattern contains $foo where the foo variable has not yet been defined. Use $$ to match a literal dollar sign.

Backref(String)

A pattern contains a back-reference to a variable that was defined in the same pattern.

For example, check: Hello $(world=.*) $world. Backreferences are not supported. Often the desired effect can be achieved with the sameln check:

check: Hello $(world=[^ ]*)
sameln: $world

DuplicateDef(String)

A pattern contains multiple definitions of the same variable.

Regex(Error)

An error in a regular expression.

Use cause() to get the underlying Regex library error.
