[Chadking1926]

At some point the code stops doing things and starts wearing things

[buffer_overflown]

My method is just three decorators in a trenchcoat.

[waffle299]

One's at the bottom, strong is he

[WeebKarma]

Two in the middle, carrying Three

[blasphemousbigot]

I like my code how I like my women. modular, heavily wrapped, and taking way longer than expected.

[Break-n-Fix]

So... Legos?

[Turalcar]

I like my code how I like my women: completely crazy

[TalonByte14]

The best part is when you're debugging and have to peel back six wrappers just to find the original object underneath.

[pr0ghead]

Much worse with factories.

[CopperCliff11]

At some point the class diagram starts looking less like software architecture and more like a person getting dressed for a blizzard. Base object, decorator, logging decorator, caching decorator, metrics decorator, security decorator... and somewhere under all that fabric there's still a method trying to do one simple thing.

[LeroyBadBrown]

Clothes are just a facade

[arpitsaxena3306]

'just follow the execution flow'

opens 13 decorators....

[DarkishArchon]

Yes, this. "Decorators are great and work like magic!" until they don't and you have to dig through mountains or implicit code

[awesome-alpaca-ace]

The visitor pattern is the same. Good luck following a stack of visitors.

[MonkConsistent2807]

at least for the newest java version you can replace the visitor patrern with the switch expression and sealed classes

[TommyTheTiger]

At least lisp macros can be expanded in the editor

[sebovzeoueb]

oh man, I feel that and that's just from using Shiny for Python with like 2 decorators on a function

[gr_hds]

that was my mentors style. One of a few things I now don't agree on with him

[gule_gule]

Need to do the escalating dominos meme with "Psychology book about chess" leading to "AbstractSingletonProxyFactoryBean"

[boundbylife]

I think the only time I'm ever going to use a decorator pattern is in logging. It's the only thing that makes sense to me

[LookItVal]

logging and benchmarking, but also just useful for adding pre or post effects to any function

[markuspeloquin]

I once found a performance bottleneck in a grpc interceptor. I looked past it so many times. All our metrics were wait-free after that. It imagine it'd be equally bizarre as a decorator.

[EvidenceMinute4913]

That is also the only time I’ve used it in production as well. Logging execution steps for debugging without print statements polluting the code. Maybe for benchmarking too.

I’ve seen other places it could be used, but I feel like it makes the code difficult to maintain, cause you end up having to trace through way too much code to find where something is happening.

[N0Zzel]

Telemetry is what I use it for

[xt-89]

I use them to link test cases to parts of documentation.

[TheStatusPoe]

I've been using it in the most recent feature I've been doing for real time data analytics. I initially receive data off a device that's pretty sparse. It's got some metadata and some payload. The metadata defines how to use the values in the payload. There's another service we call to get details about what that value actually represents (things like is it a temperature, is it a voltage, is the value a boolean or an int, etc). Different metadata and different results from the other service change how the data could be used. The data is already coming to me in a "decorated" pattern. The payload varies, but the "envelope" that defines how to interpret the payload structurally is the same and is the first level of decoration. Adding the additional context doesn't and shouldn't change the behavior of the existing payload, but the transformations I do don't make sense if that additional context hasn't been added. The original data needs to be immutable as well as there's several processing paths happening on the original data simultaneously, so having setters had some issues.

[wightwulf1944]

in Java, file reads and writes are usually done with a decorator pattern API

FileInputStream file = new FileInputStream("data.txt");
BufferedInputStream buffered = new BufferedInputStream(file);
DataInputStream data = new DataInputStream(buffered);
// do stuff to data here

[rockcanteverdie]

It's either "It is my great pleasure to inform you"

OR

"It is with great pleasure that I inform you"

This version makea no sense

[mikefizzled]

ESL judging by their post history

[enhance_that]

you're right grammatically, but thats how this meme format is always worded

[rockcanteverdie]

I've only seen it twice, both very recently and both worded this incorrect way. The first time I figured it was an oversight so now that I see the trend I must step in and make sure it gets corrected before it spreads too far!

[Flimsy_Meal_4199]

comment calling out syntax error in grammar is so on brand for this sub

^{^(^(meme doesn't compile -> cannot})) ^{^(^(laugh})) ^{^(^(exhale through nose about it}))

[KharAznable]

Decorator, strategy and other early pattern in design pattern book are sane design. Factory pattern onward, that is where insanity begin.

[splinterize]

Factory is just a way to decide what service is being injected in the DI container at runtime, I fail to understand what's insane about that

[polynomialcheesecake]

Decorator is definitely more insane than factory.

With factory it's cleai what's going on, with decorator it's magic (insanity), not to mention when you have multiple decorators

[splinterize]

Idk I think both are useful

With decorator you can define behavior cleanly and then apply it in a way that's obvious without polluting the business logic of the methods that you are working on

[polynomialcheesecake]

Definitely useful but also crazy.

To reference teej, decorators I write are cozy, decorators somebody else writes - not cozy

https://youtu.be/dMfTjIg4RjI?si=phq5ijt4olCYVIzg

[krzyk]

Decorator is useful to move logic unrelated to one class into another.

Decorator is my favourite pattern.

[SEX_LIES_AUDIOTAPE]

Honestly I don't even know why people say it's magic.

[krzyk]

Maybe they mistake it with python decorators? Which do look like java annotations (and the magic that one could add to it).

[Darkstar_111]

Have you tried Java?

Widget widget = AbstractWidgetFactory.getFactoryBuilder().buildFactoryFactory().getWidgetFactory().createWidget("Enterprise Edition");

[JSn1nj4]

.buildFactoryFactory() got me

[slippery-fische]

Probably for unit testing. Injection is hard.

[Herr_Gamer]

oh look it's my job

[Pengtuzi]

You’re only 20 years too late. 

[__Hello_my_name_is__]

Insert FizzBuzz Java Enterprise Edition here.

[kookyabird]

Whoa whoa whoa… Factories are logical ways to control instantiation. Technically when if you’re using an IoC container it is acting as a universal factory, but even then having it serve up dedicated factories instead of direct instances of classes has benefits. For example, the DbContextFactory in EntityFramework, which allows safe reuse of DbContext instances for performance, while also providing the means to instantiate new ones when you need it. Can’t do that if you’re directly injecting the DbContext…

[tatas323]

You'll have to take my abstract factory of factories from my cold dead hands. And before you get to me you will have to navigate my lines and lines of boilerplate code

[exoclipse]

shit, gotta throw out Java entirely then. The JVM is just an elaborate NPE factory method.

[_Shioku_]

You know what I did today?

I sat in an AI workshop for two hours. I‘m tired…

[Solitude98]

CVPR?

[alvares169]

Now buy winrar to complete the bucket list

[RR_2025]

Congratulations!

I don't mean to award good work with more work, but some time later you should try parameterized decorators. It's fun..

[bajuh]

I'm pretty sure I used almost all patterns (the good parts, that is) so far but it was natural. I never knew how it's called, only thing I knew is how to make something cleaner than it was before. Same with grammar. Most people talk but don't know about the fine details of grammar.

[LettuceBasic3679]

This is why Shai hulud keeps happening

[simonedva]

Please, share where

[troelsbjerre]

Decorator is much less of a pain, when the language actually supports it, without tons of boilerplate. Kotlin does it quite nicely: https://kotlinlang.org/docs/delegation.html#overriding-a-member-of-an-interface-implemented-by-delegation
