Revision 3729 - (show annotations) (download) (as text)
Fri Jan 31 10:57:53 2020 UTC (4 years, 1 month ago) by schoenebeck
File MIME type: text/x-c++hdr
File size: 4005 byte(s)
NKSP parser: track code locations also by raw byte position and length.

* NKSP VM API: Added member variables 'firstByte' and 'lengthBytes' to
  struct 'CodeBlock'.

* NKSP Editor API: Added methods firstByte() and lengthBytes() to
  class 'VMSourceToken'.

* NKSP VM language parser: track all positions also by raw byte offset
  and length (along to the already existing tracking by line/column).

* NKSP editor syntax highlighting scanner: track all positions also by
  raw byte offset and length (along to the already existing tracking by
  line/column).

* Bumped version (2.1.1.svn45).
