DWScript – October 2012 – 2.3 preview 2
A new DWScript 2.3 preview 2 7zip (422 kB) is available for download for those that don’t use the DWScript SVN. This version should be the last before a release candidate for 2.3. As the lead version is Delphi XE, users of Delphi 2009, 2010, XE2 and XE3 are especially encouraged to report any issues they encounter. FreePascal support is still considered experimental at this moment.
Re-rooting Object Pascal
A while ago I asked about the name of TObject ancestor, well, it’s now live in the SVN and its name is ‘Object‘.
Object is thus the new root class, above TObject. Eventually, it’ll be the ancestor for every other type.
DWScript for Delphi XE3
DWScript (SVN version) should now compile under Delphi XE3, thanks to Steffen Binas for providing a workaround for a compiler bug (internal error URW1147).
The workaround will alas reduce performance, for a proper fix, a futureXE3 update will be required,see QC #109187.
While I’m at it, I might also raise awareness of another XE3 bug, QC #108942 (internal error G9413).
(on a side note, my XE3 trial expired, so any fixes or workarounds for XE3 will have to come from you guys)
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).
