amber-docs VS FizzBuzz Enterprise Edition

Record patterns are one step on the path to general pattern matching utility. The bigger building block is general deconstructors. I recommend reading Functional Transformation of Immutable Objects by Brian Goetz. The idea of "withers" shown there requires deconstructors:

This is the vague plan.

You may be joking but...

Here is the much more detailed version: https://github.com/openjdk/amber-docs/blob/master/eg-drafts/reconstruction-records-and-classes.md

This kind of pattern matching is discussed in the design notes: https://github.com/openjdk/amber-docs/blob/master/site/design-notes/patterns/pattern-match-object-model.md

True, but that only pushes the question of value down the line.

I'm curious about lenses because Java did have a serious problem that required a solution: working with "simple" data correctly was difficult. The chosen solution was ADTs, so we did buy into that. But the approach being explored for transforming records (https://github.com/openjdk/amber-docs/blob/master/eg-drafts/...) only works one level at a time rather than for an entire path. So I wonder how valuable it would be to have a solution for paths. If the answer is that it's mostly valuable for an approach we haven't bought into yet, then we might not need to consider it just yet.

Just a heads up, something like that spread operator is actually coming sooner or later to java: https://github.com/openjdk/amber-docs/blob/master/eg-drafts/...

Pattern matching (for records) is already a preview feature.

That "Hello World Enterprise Edition" looks dangerously under-engineered - I could understand it! Far better to follow the best practices demonstrated in the Fizz Buzz Enterprise Edition...

Clean code is a balancing act - you’ll want to make sure you don’t turn your codebase into something like this.

It seems to me that all large software projects eventually grow into "Enterprise" code. What I mean by this is something like FizzBuzz Enterprise Edition; large codebases with many layers where Design Patterns and SOLID principles are applied vigorously.

???

I'll answer your question with a question: Have you seen https://github.com/EnterpriseQualityCoding/FizzBuzzEnterpris... ? :)

I'm guess that to those of us who remember when Java came out, "FizzBuzz: EE" is what we think of when we think of Java. :P

In Java I have to type a bazillion characters to get anything done! And make all these useless directories and files and InterfaceClassFactoryProtocolStreamingSerializer BS. And worry about how that executes.

C++? No bloat*, just speed

*Yes, there's some _optional_ bloat. But compared to Java? no contest.
