Spotlight on dwsJSON

dwsJSON is a unit that supports JSON parsing/creating, it’s part of DWScript but relatively “standalone”, in that if you add it in your Delphi (or FPC) projects, it won’t pull the whole of DWScript library, and thus can be used anywhere you need.

The JSON parser in dwsJSON generates an object tree based on TdwsJSONValue (and its subclasses), you can also create such a tree from scratch and use it to spit out JSON. There is also a low-level JSON writer for fast, write-only streaming. All classes support full Unicode (in Delphi) as well as very long strings (like a base64 streamed image).

This site and news have been neglected for much of 2016, this year’s resolution will be to try and revive it a bit.

In particular announcements and articles have fallen way behind the code as far as DWScript is concerned. So I will start the year by attempting to rectify that.

Fuzz Testing in Delphi

Monkey-typingI am a big fan of TBCEditor by Lasse Rautiainen, in case you have not heard about it, it is fork of SynEditthat diverged very significantly and includes support for code folding, fully JSON-based syntax highlighters, minimap and many other features.

Of course a code editor is a very complex piece of software, with many opportunities for bugs to hide. I have been helping by providing some Fuzz Testing code and vectors.
