You know what really sucks?

When I have a method that returns a Foo and like 300 places it gets called.

And then I change it to return an ever so slightly different Bar

Ah, now I need to go and update the code in 300 places cause the return type changed.

"Can't you just sed your codebase?"

Maybe, but it could cause some serious unintended dawizard

The solution to this problem (and many others) is to use an IDE / editor which supports refactoring like that. Which is pretty much every IDE / editor unless you're using some very obscure language I think.

anything that supports your language's language server protocol

Yup, that's what I meant. I really don't see why anyone wouldn't use it nowadays.

I dont think external tooling should be a factor in deciding your language's definition.

[-] lseif@sopuli.xyz 1 points 7 months ago

a lot of languages these days ship with tooling.

[-] sudo@programming.dev 1 points 7 months ago

That doesnt change my point. The tooling is completely downstream of the language.

Hello!

This is the current Lemmy equivalent of https://www.reddit.com/r/ProgrammingLanguages/.

The content and rules are the same here as they are over there. Taken directly from the /r/ProgrammingLanguages overview:

This community is dedicated to the theory, design and implementation of programming languages.

Be nice to each other. Flame wars and rants are not welcomed. Please also put some effort into your post.

This isn't the right place to ask questions such as "What language should I use for X", "what language should I learn", and "what's your favorite language". Such questions should be posted in /c/learn_programming or /c/programming.

This is the right place for posts like the following:

"Check out this new language I've been working on!"
"Here's a blog post on how I implemented static type checking into this compiler"
"I want to write a compiler, where do I start?"
"How does the Java compiler work? How does it handle forward declarations/imports/targeting multiple platforms/?"
"How should I test my compiler? How are other compilers and interpreters like gcc, Java, and python tested?"
"What are the pros/cons of ?"
"Compare and contrast vs. "
"Confused about the semantics of this language"
"Proceedings from PLDI / OOPSLA / ICFP / "

See /r/ProgrammingLanguages for specific examples
