ValidationRuleParser

Create a new validation rule parser.

Parse the human-friendly rules into a full rules array for the validator.

Explode the rules into an array of explicit rules.

Explode the explicit rule into an array if necessary.

Prepare the given rule for the Validator.

Define a set of rules that apply to each element in an array attribute.

Uses a direct tree walk instead of flattening the entire data array with Arr::dot() and regex matching. This is O(n) in the number of matching keys instead of O(n*m) where m is the total flattened key count. Port of laravel/framework PR #59287.

Explode wildcard rules using the original flatten + regex approach.

Used for CompilableRules which need the flattened data context that the tree-walk path doesn't provide.

Expand a wildcard attribute into all matching concrete keys by traversing the data structure directly.

Recursively traverse data segments to expand wildcard keys.

Determine if a rules array contains any CompilableRules at any nesting level.

Checks both top-level elements and elements inside nested arrays, so mixed rule arrays like ['nullable', Rule::forEach(...)] are detected.

Merge additional rules into a given attribute(s).

Merge additional rules into a given attribute.

Extract the rule name and parameters from a rule.

Parse an array based rule.

Parse a string based rule.

Parse a parameter list.

Determine if the rule is a regular expression.

Normalizes a rule so that we can accept short types.

Expand the conditional rules in the given array of rules.

Flush all static state.
