read-from-file

Reads new contents for the editor from a stream. The return value is #t if there are no errors, #f otherwise. See also File Formats.

The stream provides either new mappings for names in the editor's style list, or it indicates that the editor should share a previously-read style list (depending on how style lists were shared when the editor was written to the stream; see also write-to-file).

• In the former case, if the overwrite-styles? argument is is #f, then each style name in the loaded file that is already in the current style list keeps its current style. Otherwise, existing named styles are overwritten with specifications from the loaded file.
• In the latter case, the editor's style list will be changed to the previously-read list.

• (send a-text read-from-file stream start overwrite-styles?) -> boolean
      stream : editor-stream-in% object
      start : exact non-negative integer or 'start
      overwrite-styles? = #t : boolean

  New data is inserted at the position indicated by start, or at the current position if start is 'start.
