[Перевод] Разрыв в неизменяемости: почему Java Records нужны оптики (Lenses)

Records, pattern matching и sealed-типы сделали Java куда более «функциональной» — читать вложенные данные стало легко и красиво. Но как только вам нужно изменить что-то глубоко внутри неизменяемой структуры, начинается боль: каскад пересоздания records, копирование полей, десятки строк ради одного изменения. В новом переводе от команды Spring АйО рассмотрим, почему у современной Java всё ещё есть пробел в истории неизменяемости — и как оптики закрывают его. Если pattern matching — это про элегантное чтение , то оптики дают то, чего так не хватает, — композиционную запись : определили путь один раз и дальше меняете вложенные поля одной строкой, без ручной реконструкции и без циклов.

With the rail done my #optics #microscopy project is going into the next phase meaning new problems. I want to use a beam splitter to direct some light to a guide camera (small Basler Cam on the side). However astigmatism from the 50/50 mirror is so bad that I don't get a usable image. Help?!

I purchased a 1924 Bausch & Lomb Balopticon (https://archive.org/details/balopticonsacces00baus/mode/2up) today. It's in pretty rough condition (missing some parts, the bottom of it is rusted almost all the way through, etc.), but I mostly just wanted the lenses. I managed to get the larger of the two off without any trouble and it is a *chonk*. 4x5 cameras for scale. It weighs just over 12lbs. 😂

Not sure what to do with it yet. Any thoughts?

Uniting Optics with Effects in a fluent api.

Functional Optics for Modern Java - Part 5

A unique feature of Higher-Kinded-J is uniting Optics with Effects in a fluent api. In Part 5 we dive into effect polymorphism and how effects structure our code with Higher-Kinded-J's Effect Path API; a fluent interface for computations that might fail, accumulate errors, or require deferred execution.
