Abstract:

A computer program describes not only the basic computations to be performed on input data, but also in which order and under which conditions to perform these computations. To express this sequencing of computations, programming language provide mechanisms called control structures. Since the "goto" jumps of early programming languages, many control structures have been deployed: conditionals, loops, procedures and functions, exceptions, iterators, coroutines, continuations… After an overview of these classic control structures and their historical context, the course develops a more modern approach of control viewed as an object that programs can manipulate, enabling programmers to define their own control structures. Started in the last century by early work on continuations and the associated control operators, this approach was recently renewed through the theory of algebraic effects and its applications to user-defined effects and effect handlers in languages such as OCaml 5.

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
