DataFixerUpper VS hoogle

You don't need to load a world in every version and in fact this is not recommended because later versions fix various bugs with converting older worlds and with the exception of Beta 1.3 (Alpha to Region*) and release 1.2 (Region to Anvil*) only chunks you've loaded will be converted (since 1.13 there is an "optimize world" feature which can force a full conversion and is recommended mainly to avoid lag due to the game converting chunks on the fly; modern versions change data formats so often Mojang created an entire "data fixer" library and data versioning so it can tell exactly what version a file was last saved in and update it properly, anything without a version tag is assumed to be pre-1.9, which barely changed aside from Alpha-Region-Anvil).

No need to guess, we know pretty much exactly what this is referring to, because it was performance changes in one of the open-source components, DataFixerUpper. The code is open to the public, and you can look at the changes yourself if you want to. It's somewhat technical but I'll try to explain.

Read it and weep! https://github.com/Mojang/DataFixerUpper

java and generics mentioned in the same headline and noone's linked the funny library yet, smh

And I work on Minecraft.

DataFixerUpper, particularly codecs

You can write a library for profunctor optics, something that is usually used in functional languages like Haskell, in Java, but that doesn't mean it's convenient or even practical to use.

Dimensions behave somewhat like a "type system" for math. These dimensional-analysis tricks act like the trick you see in Haskell sometimes, where you can easily guess an implementation of an expression once you know it's type (or e.g. search by type signature https://hoogle.haskell.org/ )

Haskell Spotlight makes vscode a client for hoogle. It isn't too different than jumping into your browser and type https://hoogle.haskell.org/. The main advantage is that you have everything in one place

https://hackage.haskell.org/package/base and https://hoogle.haskell.org are automatically up to date and better searchable than almost any other reference of any other programming language. maintaining a redundant reference that needs to be kept up to date manually is simply stupid.

Ideally like this: https://zio.dev/reference/#concurrency

Or this: https://hoogle.haskell.org/?hoogle=fork

And yeah I get it, it's hard to Google for punctuation operators in languages because it doesn't give useful search results (but not impossible, for example, Haskell has a search engine for documentation that handles symbols/punctuation).

{ "customLocalFormatters.formatters": [ { "command": "make format", "languages": ["haskell"] } ], "emeraldwalk.runonsave": { "commands": [ { "match": "*.hs", "isAsync": true, "cmd": "make retag retag_file=${file}" } ] }, "ghcid.command": "make ghcid", "goto-documentation.customDocs": { "hs": "https://hoogle.haskell.org/?hoogle=${query}" } }

You had a look at Hoogle?

For some type signatures there is (are) only one (or only a few) meaningful implementation(s).
