Outcome conditions

You need to replace ${name} with its actual canonified value.

✅ Ok: variable_iterator_from_file_${name}_ok
- ☑️ Already compliant: variable_iterator_from_file_${name}_kept
- 🟨 Repaired: variable_iterator_from_file_${name}_repaired
❌ Error: variable_iterator_from_file_${name}_error

Example

method: variable_iterator_from_file
params:
  comments_regex: VALUE
  prefix: VALUE
  name: VALUE
  file_name: VALUE
  separator_regex: VALUE

The generated variable is a special variable that is automatically iterated over. When you call a generic method with this variable as a parameter, n calls will be made, one for each items of the variable. Note: there is a limit of 10000 items Note: empty items are ignored

To use the generated variable, you must use the form ${prefix.name} with each name replaced with the parameters of this method.

Be careful that using a global variable can lead to unpredictable content in case of multiple definition, which is implicitly the case when a technique has more than one instance (directive). Please note that only global variables are available within templates.
