This method parses a stream from a fileout with styling and generates the text style specific objects. Now, 1) are we writing that style section in our fileouts? 2) Is this really necessary in RunArray? It's class comment does not say anything to me about Text nor TextStyle or stuff: "My instances provide space-efficient storage of data which tends to be constant over long runs of the possible indices. Essentially repeated values are stored singly and then associated with a "run" length that denotes the number of consecutive occurrences of the value." The method is the following: scanFrom: strm "Read the style section of a fileOut or sources file. nextChunk has already been done. We need to return a RunArray of TextAttributes of various kinds. These are written by the implementors of writeScanOn:" | runs values attrList char | (strm peekFor: $( ) ifFalse: [^ nil]. runs := OrderedCollection new.
