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.
Kudos to @sglienke
BTW, Use the develop branch (which is 2.0rc5) - it’s very stable.
Feel free to chime in with any others you have discovered.
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).
Thanks for the tip on 2.0rc5.
FWIW Kudos for TBuffer and most things in Spring.Crypto goes to Baoquan Zuo (aka Paul) the author of Spring4D.
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
