Support for ?? (double question mark) as the coalesce operator has been added to DWScript.
The coalesce operator is a binary operator, which looks at its left operand, and if not “falsey”, returns it, otherwise returns its right operand.
A new syntax-highlighting editor has been unleashed upon the Delphi world by Lasse Rautiainen, it’s named TBCEditor, and it is quite full-featured, clean, stable and fast.
The main source code is TBCEditor on github and supports Delphi XE4-XE8, I have made a fork TBCEditorXE on bitbucket which supports XE.
Here is a quick guide on migrating a project code from Google Code (SVN) to BitBucket (git) using TortoiseGIT, so with a GUI, and with no cryptic command line in sight.
Migrating Wiki/Issues is a bit more involved and not covered here. Migrating downloads has to be done by re-uploading to BitBucket (but at least BitBucket supports binary downloads).
With the closing of Google Code, I will be moving my projects, a priori to BitBucket.
The new URL is https://bitbucket.org/egrange/dwscript
If you have Issues in the Google Code Issue Tracker that matter to you, please copy-paste them to the BitBucket Issue Tracker.
Hash, IndexOf, Lookup, Performance, Search, Sorted, String
As a followup to the previous String Lookup: Hash, Sorted or Unsorted here is a look at what happens for longer strings.
When the string you’re searching have more than a dozen characters, and you only have a few hundreds of them, a clear winner emerges.
When looking up a string, what is the fastest strategy?
A hash map, a sorted list or an unsorted list?
Of course it depends on how many strings you have, but where are the cutoff points?
Here is a quick test, and an interesting tidbit is uncovered…
(more…)
A trivial way to turn a case-sensitive String hash function into a case-insensitive one is to to pass a lower-case (or upper-case) version of the String.
However, in our days of Unicode strings, this is not innocuous…
A new version 2014.10.15 of the DWS Web Server 
is available.
This version contains a variety of improvements and fixes, along with a new sample for JS libraries.
The pre-compiled 2014.10.13 version of the DWScript WebServer is now available!
This version includes the Pascal to JavaScript CodeGen!
Below is a quick summary of changes in the SVN since the last post.
There is also a mini-sneak peek of things to come!
