I have an interesting idea how to preserve comments & layout information. The relevant structures should be included in the tree under a special meta key:
Config file:
key1 data1 ;comment before key2 key2 data2 ;comment after key2, on the same line
The resulting tree might look like that:
key1 data1 key2 data2 _metadata_ { key1 { row 1 column 1 } comment "comment before key2" { row 2 column 1 } .. etc }
It may be needed to store also: * location of data * anything in between key and data (=, spaces) * information about any transformations made by the parser (e.g. transparent handling of \ at the end of lines, escape sequences if they are used, presence or lack of parenthesis, their kind, numeric formatting, ...) If one deletes a data item will the corresponding metadata dissappear automatically? The metadata my use different allocator than the 'normal' data. /Pavel
