I absolutely love the Spring4D libraries and have used them for years. But I am realising I have only scratched the surface. So I thought I would post some of my favourite but less well known features.
I was today years old when I discovered the TBuffer type - it’s part of the cryptography code - but it’s immensely useful
Assignable to/from TBytes
ToHexSting method
Load from/save to TStream
ToString method
Access to the underlying memory via Memory property (pointer).
Size property
Bitwise And/Or/Xor operations.
It’s just an incredibly well thought out type. It’s basically what TBytes should have been!
I only discovered it today when I needed to do some hashing - the spring4d crpytography code is pretty neat too, with support for MD5, SHA1,SHA256, SHA384 and SHA512.
The whole of Spring4D is a gem. I too have only scratched the surface (we primarily use the core features in Collections, Services, Container). I haven’t looked at new features or changes for the last couple of years (note to self - to review).
One hidden gem that we use is Spring.SystemUtils.TEnum that provides convenient ways to convert between enums and strings and integers (e.g. persistence).
I love DelphiPraxis but it sucks for notifications - any post into the Google group directly goes to my emails (well when Google does not mess it up and leaves it closed for ages due to a false positive on some malicious content filter)
The same is the case for StackOverflow - once a week or so I check the spring4d tag.
I use RSS - I have a “bot” (at the moment, a service on a Windows machine) that checks feeds, and posts new entries to related channels in my Slack workspace, e.g. #forum-posts for DP and SO, and #qp for Quality Portal
