Class Methods
.new
Creates a new PLtuple object.
Arguments:
| list |
Symbol or Ptuple list arg. If a Symbol is passed, list can be assigned to an envir variable later on. This lists's elements can be dynamically replaced by Patterns or Streams. |
| repeats |
Symbol or Ptuple repeats arg. If a Symbol is passed, repeats can be assigned to an envir variable later on. Defaults to inf. |
| cutItems |
Symbol or Boolean or Integer (0 or 1) or a Function returning Boolean or Integer. If a Symbol is passed, cutItems can be assigned to an envir variable later on. Determines if list items, which are Patterns or Streams themselves, will be finished if a replacement occurs during their embedding, or if they will be replaced immediately. The latter is the default behaviour (default value true). For protecting whole lists from immediate replacements see PLn. |
| envir |
Dictionary or one of the Symbols \top, \t (topEnvironment), \current, \c (currentEnvironment). Dictionary to be taken for variable reference. Defaults to \current. |
