Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

A metaprogrammer should be able to reason about the semantics of the generated code.Multi-stage programming introduced an elegant and powerful solution to this problem.It follows a semantically driven approach to code generation, where semantics are fully ...

Proof of Multi-Stage Programming with Generative and Analytical Macros

Martin Odersky, Nicolas Alexander Stucki, Jonathan Immanuel Brachthäuser

In metaprogramming, code generation and code analysis are complementary. Traditionally, principled metaprogramming extensions for programming languages, like MetaML and BER MetaOCaml, offer strong foundations for code generation but lack equivalent support ...

EPFL2021

Scala 3 provides a metaprogramming interface that represents the abstract syntax tree definitions using algebraic data types. To allow the compiler to freely evolve without breaking the metaprogramming interface, we present virtual algebraic data types (or ...

Semantics-preserving inlining for metaprogramming

Martin Odersky, Sébastien Jean R Doeraene, Nicolas Alexander Stucki

Inlining is used in many different ways in programming languages: some languages use it as a compiler-directive solely for optimization, some use it as a metaprogramming feature, and others lay their design in-between. This paper presents inlining through ...

A Practical Unification of Multi-stage Programming and Macros

Martin Odersky, Nicolas Alexander Stucki

Program generation is indispensable. We propose a novel unification of two existing metaprogramming techniques: multi-stage programming and hygienic generative macros. The former supports runtime code generation and execution in a type-safe manner while th ...

Truly abstract interfaces for algebraic data types: the extractor typing problem

Martin Odersky, Nicolas Alexander Stucki, Paolo Giosuè Giarrusso

Pattern matching enables inspecting algebraic data types, but typically prevents hiding the implementation of the matched algebraic data type. In Scala, instead, extractors also allow pattern matching on non-algebraic data types and invoking methods on the ...

Dotty Phantom Types

Martin Odersky, Nicolas Alexander Stucki

Phantom types are a well-known type-level, design pattern which is commonly used to express constraints encoded in types. We observe that in modern, multi-paradigm programming languages, these encodings are too restrictive or do not provide the guarantees ...

Linker call graph with full Dotty support

Nicolas Alexander Stucki

This project consisted in bringing the linker call graph up to date with dotty/master, restructure the code, make it support the full Scala language and make it support calls to Java code. Also implemented dead code elimination of unreachable methods based ...

Semantics-Driven Interoperability between Scala.js and JavaScript

Sébastien Jean R Doeraene, Nicolas Alexander Stucki, Tobias Schlatter

Hundreds of programming languages compile to JavaScript. Yet, most of them fail, at one level or another, to provide satisfactory interoperability with JavaScript APIs. This is limiting, as interoperability is at least required to manipulate web pages thro ...

Generics on the Java platform are compiled using the erasure transformation, which only supports by-reference values. This causes slowdowns when generics operate on primitive types, such as integers, as they have to be transformed into reference-based obje ...
