New SWAG Pascal database viewer
Just released the first beta of a new web application that displays the content of the old SWAG Pascal code database. There's no new code but the database has been tidied up a little and the new interface is, I hope, cleaner than the old versions. Any feedback welcome.

Two new URI encode / decode routines added to Code Snippets Database
Two new snippets, URIEncode and URIDecode, have been added to the Code Snippets Database. URIEncode URL encodes a string according to RFC 3986 while URIDecode decodes an encoded string back to its original form. Both routines have the option to encode and decode URL query strings. These routines supersede URLEncode and URLDecode which are not standards compliant.

CodeSnip v4.4.1 released - fixes bug in v4.4.0
CodeSnip v4.4.1 has just been rushed out to fix a silly little bug in v4.4.0 that I really should have noticed before release. The program was using the wrong URL for web services, giving a 404 error. I've patched the website to recognise the bad URL and redirect it to the correct place, so the bug shouldn't bite you now - no more 404 errors in v4.4.0 now! Best to update though. That'll teach me to test only on my development web server and forget to test on the live server!

CodeSnip v4.4.0 has been released
CodeSnip v4.4.0 has just been released. It adds a facility to automatically check for program and online Code Snippets database updates. Update checking runs in a background thread and any available updates are notified to the user by means of a small pop up window at the bottom right of the main window. By default CodeSnip checks for updates no more that once per week. The frequency can be changed or the feature switched off from the Updates tab of the Preferences dialogue box.

6 assorted snippets added to the Code Snippets Database
A rag-bag of six unrelated snippets has been added to the Code Snippets Database. The snippets are: GetDefaultPrinterName - returns name of any default printer on the computer; DirPurge - deletes a directory and all its contents; FileInProgramDir - returns the path to a given file, located in side the same directory as the program; SafeFreeEncoding - frees a TEncoding object unless it is one of the standard encodings; IsIEInstalled - checks if Internet Explorer is installed; EnglishColorName - returns the name of a known colour in American English.

Released v3.0 of the Console Application Runner Classes
v3.0 of the Console Application Runner Classes project. The main change is the removal of the PJPipe, PJPipeFilters and PJFileHandler units following their inclusion in the recently released I/O Utility Classes project. The remaining PJConsoleApp unit has been prepared for use with Delphi XE2 and later - the code's dependence on the VCL has been removed to permit its use in both VCL and FireMonkey projects. In addition the code now compiles and works correctly with either 32 or 64 bit Windows targets. Demos have been tidied up and three new FireMonkey demo projects have been added.

New I/O Utility Classes Delphi Library project (v1.0.0)
A new "I/O Utilities Classes" project has been added the Delphi Library. This contains the PJPipe, PJFileHandle and PJPipeFilters units taken from the Console Application Runner Classes project. I've done this because these classes are of more general use than simply helping to interface with console applications. The units will be removed from the next release of the Console Application Runner Classes project. The units have been updated to work correctly with both the Windows 32 and 64 bit Delphi XE2 and later compilers. The code is suitable for use with both VCL and FireMonkey projects.

Four new tips from the former Delphi Pool website have been added to the Delphi Tips database, starting from tip #214. They are: tip #214, "How to create a GUID"; tip #215, "How to create a greyscale palette"; tip #216, "What is a DispInterface?" and tip #217, "The purpose and use of DispInterface".

Added two new maths routines to the Code Snippets Database
Two new routines have been added to the Mathematics category of the Code Snippets database. The first, Pow, raises an integer to value to a non-negative integer power. The second snip is named SAR and performs an arithmetic right shift operation on an integer (Pascal's 'shr' is a logical left shift operator). Don't forget that new snippets now don't display in the old Code Snippets online viewer - you need the CodeSnip program or the new viewer at to see them.
