amber-docs VS prettier-java

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.

I ended up, from a friend suggestion, looking into a java prettier plugin. Prettier allowed for an easy integration with most Web IDE, can be configured to format on save for vscode and is trivial to run in CI.

Prettier does not natively support Java, they have a community plugin for Java https://github.com/jhipster/prettier-java (link is from prettier.io) are you using this? I don't use prettier with Java though, Im not sure it works with the VS Code extension out of the box. prettier by itself is a separate thing from the VS Code extension

I didn’t realize prettier was used for other languages. I’ve been kinda frustrated with our java formatter at work, so I took a look at the prettier java formatter: https://github.com/jhipster/prettier-java

Prettier has support for Java. https://github.com/jhipster/prettier-java

Did you know Prettier for Java is a JHipster project?
