IDE as a Front-end and Fast time-to-market language support in Eclipse IDE relying on LSP, TextMate and CLI
C# and Rust case studies
Dynamic programming languages execute behaviors like extending code or modifying types at runtime rather than during compilation. They are well suited for rapid prototyping, have good string processing capabilities, and allow for highly expressive and readable code. C# 4.0 introduced the dynamic keyword to optionally add dynamic features to a statically typed language via the Dynamic Language Runtime (DLR).
The document discusses Microsoft .NET platform. It states that .NET is a software platform and framework that allows development of applications for web and Windows. The .NET framework provides a common language runtime (CLR) environment that executes all .NET programs. The CLR offers thread and memory management. Languages compile code into Microsoft intermediate language (MSIL) that runs on the CLR. The .NET framework also includes a base class library (BCL) of common functions that can be used by all .NET languages. It ensures different .NET languages can interact through a common type system.
The Hitchhiker's Guide to Faster Builds. Viktor Kirilov. CoreHard Spring 2019corehard_by
C++ is known for things such as performance, expressiveness, the lack of a standard build system and package management, complexity and long compile times. The inability to iterate quickly is one of the biggest killers of productivity. This talk is aimed at anyone interested in improving the last of these points - it will provide insights into why compilation (and linking) take so long for C++ and will then provide an exhaustive list of techniques and tools to mitigate the problem, such as: - tooling and infrastructure - hardware, build systems, caching, distributed builds, diagnostics of bottlenecks, code hygiene - techniques - unity builds, precompiled headers, linking (static vs shared libraries) - source code modification - the PIMPL idiom, better template use, annotations - modules - what they are, when they are coming to C++ and what becomes obsolete because of them
The document discusses the LLVM compiler framework and infrastructure. It provides reusable components for building compilers to reduce the time and cost of building new compilers. The LLVM compiler framework uses the LLVM infrastructure to build static compilers, JITs, and trace-based optimizers. It emits C code or native code for x86, Sparc, and PowerPC architectures. The three primary LLVM components are the virtual instruction set (the common language- and target-independent intermediate representation), a collection of well-integrated libraries, and a collection of tools built from the libraries.
This document discusses creating LiveCode Builder extensions, including libraries and widgets. It covers:
- Creating a "Hello World" library that extends LiveCode with a function to return "Hello World!"
- Compiling the library and installing it into the LiveCode IDE
- The differences between libraries and widgets and when each should be used
Build Great Networked APIs with Swift, OpenAPI, and gRPCTim Burks
This document discusses building APIs with Swift, OpenAPI, and gRPC. It introduces protocol buffers for defining data structures, and gRPC for building APIs. It recommends using the gnostic tool to convert OpenAPI descriptions to protocol buffers for use with gRPC plugins. This allows building high-quality code generators in different languages by separating the generator from the API description parsing. The document provides examples of building gRPC APIs and clients in Swift.
C++ CoreHard Autumn 2018. Создание пакетов для открытых библиотек через conan...corehard_by
Использование сторонних библиотек в языке C++ никогда не было простым - необходимо было правильно собрать их, имея дело с различными системами сборки, но с появлением пакетного менеджера conan.io процесс стал намного проще, так что теперь осталось только сделать пакеты для нужным библиотек, и в этом поможет команда bincrafter-ов.
The LLVM project is a collection of compiler and toolchain technologies, including an optimizer, code generators, and front-ends like llvm-gcc and Clang. The project aims to provide modular, reusable compiler components to reduce the time and cost of building compilers. It also seeks to implement modern compiler techniques to generate fast, optimized code. LLVM has been used to build fast C/C++ compilers like LLVM-GCC that show improvements in compilation speed and generated code quality compared to GCC.
LLVM is a compiler infrastructure that provides modular and reusable compiler components. It supports link-time optimization (LTO) which allows interprocedural optimizations by treating LLVM bitcode files like native object files during linking. LTO involves four phases: reading bitcode files, symbol resolution, optimizing bitcode, and final symbol resolution. It uses the libLTO shared object to handle LLVM bitcode, performing operations like creating and disposing modules, querying symbols, and compiling to a native object file.
The document discusses using gRPC and Protocol Buffers to build fast and reliable APIs, describing how gRPC uses Protocol Buffers to define service interfaces and handle serialization, and allows building clients and servers in various languages that can communicate over the network through language-independent services. It provides examples of using gRPC to define and call both unary and streaming RPC services from Swift clients and servers.
Thesis - LLVM toolchain support as a plug-in for Eclipse CDTTuononenP
Integrates LLVM toolchain tools to Eclipse CDT IDE. It allows build automation and configuration via GUI. The first and currently the only cross-platform and open-source IDE that supports LLVM via this plug-in.
LLVM is a compiler and toolkit for building compilers that converts source code into machine-readable code. It started at the University of Illinois in 2000 and provides modular, reusable technologies. LLVM differs from GCC in that it is a framework for generating code from any source, rather than supporting specific languages. It works by using Clang to turn source into an intermediate representation, then optimizes and converts it to machine code. LLVM can optimize code aggressively during compilation and linking but does not handle language parsing or memory management itself.
The document provides an introduction to .NET, describing what it is, its core components like the .NET Framework and Common Language Runtime (CLR), advantages such as cross-language development and improved security, and popular languages for .NET development like C# and Visual Basic .NET. Key aspects of the .NET Framework are outlined, including namespaces for organizing classes, support for web standards, and ADO.NET for database access. Differences between C# and Visual Basic .NET are highlighted, such as syntax and intended uses as a rapid application development tool.
Docker Amsterdam Summer meetup, August 2014: using Docker at Cloud9 IDE
This talk showcases how we use Docker at c9.io, and highlights some of the challenged we faced in adopting docker for our use case.
Clang Static Analyzer is an open source static analysis tool that was released in 2005 and is extensively used by Apple. It integrates with Xcode to identify possible runtime errors in code as it is being written in real time with minimal setup effort and no additional computing resources required. Clang is free to use, updated regularly, and while it will not find all errors, it provides suggestions to help improve code quality and catch syntax issues.

Three talks in one:
- The power of limits: Partial continuations in Scheme
- Postcards from the web: Lessons from JavaScript
- Guile in 2012: A look back at 2.0, a look forward to 2.2
The power of limits: Partial continuations in Scheme
I’ll describe what delimited continuations are, how they are better than call/cc, and then go on to demonstrate and describe an event-based cooperative threading system built with delimited continuations, showing how it makes for much clearer code. I’ll show a simple implementation of the memcached protocol.
Postcards from the web: Lessons from JavaScript
In this talk I will mention some things that I have learned about language implementations from having worked on V8 and JavaScriptCore.
Guile in 2012: A look back at 2.0, a look forward to 2.2
It will briefly summarize the 2.0 release series of Guile, how it went, what worked well and what didn’t. Then we’ll look forward to the next cycle, which is probably some 6 months away.
This ppt will demonstrate the compilation process stages in C language. C compilation process has 4 stages. They are pre-processor, compiler, assembler and linker. Each stage has its own functionality. The final outcome of these stages would be a C executable file. GCC tool is used in linux platform to compile C code. And It will generate *.out files as an executable.

Jit builder status and directions 2018 03-28Mark Stoodley
Quick status summary of the JitBuilder library at the Eclipse OMR project, followed by the areas the community is currently focusing on for 2018. This presentation is a starting point for ongoing discussion with the community of users and contributors; there are many GitHub issue links where you can join us to participate in the evolution of this exciting project!
PyPy is a Python implementation that uses a just-in-time (JIT) compiler. It is written in RPython, a restricted subset of Python, and uses a translation framework to generate C code from RPython programs. This allows PyPy to run programs faster than the standard CPython implementation while also supporting features like lazy evaluation, pluggable object spaces, and stackless concurrency.
The core idea of PyPy is to produce a flexible and fast implementation of the Python programming language. The talk will cover the interpreter, translator and jit parts of the code and their relationships and the fundamental ways in which PyPy differs from other virtual machine implementations.
Minko - Build WebGL applications with C++ and asm.jsMinko3D
This document summarizes an HTML5 Meetup about building WebGL applications with C++ and ASM.js. It discusses how C++ is more expressive than JavaScript for complex 3D applications and allows leveraging existing C++ libraries and performance through GPU programming. It outlines using Emscripten to cross-compile C++ to JavaScript, generating optimized ASM.js code. It also discusses tools like Premake for cross-platform building and Vagrant for consistently provisioning the build environment. Examples are given of building a 3D application with C++ and WebGL that runs across desktop, mobile and web with good performance and binary size.
Multiplatform C++ on the Web with EmscriptenChad Austin
IMVU is using Emscripten to bring its multiplatform C++ codebase to web browsers with HTML5 and WebGL. See how Emscripten works, how to use, and what you can expect.
This document discusses using Emscripten to compile C++ code to JavaScript. It shows how Emscripten adds an asm.js backend to LLVM, allowing any LLVM-supported language like C++ to target JavaScript. Benchmarks show Emscripten-compiled code runs faster than native JavaScript for tasks like summing arrays and matrix multiplication by using optimized libraries and compiler optimizations not available to JavaScript. The document advocates using Emscripten to compile C++ to JavaScript when performance is important, as it allows using the best tools and libraries for the job.
The document discusses implementing dynamic programming languages in virtual machines. It argues against directly writing virtual machines in low-level languages like C, which can limit flexibility, maintainability and performance. Instead, it advocates writing interpreters in high-level languages and using meta-programming techniques to automatically generate virtual machines from these interpreters through translation. This approach aims to achieve flexibility, simplicity and performance together for language implementations.
RubyCocoa allows Ruby scripts to access and control Objective-C objects. It automatically creates Ruby proxy objects that are bridged to Objective-C classes, forwarding Ruby messages to instances of Objective-C classes. This allows mixing Ruby and Objective-C in the same source files. RubyCocoa is officially supported by Apple and supports key Cocoa features. To use it, one imports the RubyCocoa framework, subclasses NSObject in Ruby, and connects Ruby controllers to outlets and actions in Interface Builder. A demo showed controlling a Lego Mindstorms NXT robot via Bluetooth using the ruby-nxt gem.
[EclipseCon France 2017] Language Server Protocol in actionMickael Istria
The Language Server Protocol in a popular IDE-independent and Language-independent interface to provide and consume language edition services - such as code analysis, completion, hyperlinking... It basically lets the language providers implement the protocol as a server, and the IDEs consume the protocol as a client to have the IDEs presenting the language-specific data without having to know about the language.
This protocol already has multiple successful stories. In this talk we’ll demonstrate:
* How a C# language server can be used in Eclipse IDE (thanks to LSP4E) to provide rich C# edition capabilities
* How a Java language server implemented on top of JDT is integrated into VSCode to have VSCode supporting rich Java edition capabilities
* How you can easily write a language server in Java (with LSP4J) and plug it into Eclipse IDE (with LSP4E) and VSCode and demonstrate how easy it becomes to ship additional features for your language in all tools at once.

ConFoo Montreal - Microservices for building an IDE - The innards of JetBrain...Maarten Balliauw
Ever wondered how IDE’s are built? In this talk, we’ll skip the marketing bit and dive into the architecture and implementation of JetBrains Rider. We’ll look at how and why we have built (and open sourced) a reactive protocol, and how the IDE uses a “microservices” architecture to communicate with the debugger, Roslyn, a WPF renderer and even other tools like Unity3D. We’ll explore how things are wired together, both in-process and across those microservices. Let’s geek out!
While the Language Server Protocol (LSP) has quickly become an industry standard in the devtools domain and Eclipse IDE promptly got support for it with the Eclipse LSP4J and LSP4E projects, LSP is only targetting the code edition activity. However, code edition is just one activity amongst others for a developer, and some would argue that it's not the main use-case that justifies usage of an IDE over a simple text editor.
One of the most important activity (where IDEs are usually better than other tools) for a developer is debugging: watching a program run, digging hints of what could be wrong, experimenting things against the running application... Similarly to the Language Server Protocol, as part of Visual Studio Code, a JSON-based language and tool agnostic protocol was created to support typical debug interactions and facilitate the binding of a devtool with a debugger. Eclipse LSP4J and LSP4E enabled in early 2018 support for this Debug Adapter Protocol in Eclipse IDE.
Eclipse aCute, providing an IDE for C# and .NET Core, managed to use this Debug Adapter Protocol and the existing integrations with Eclipse IDE to relatively easily and quickly integrate support for netcoredbg, an open-source debugger for .NET Core.
In this presentation, we'll explain how the Debug Adapter Protocol works, how LSP4J can be used to support it in any Java application (either a debugger or a client), how LSP4E can be used to support it out-of-the-box in Eclipse IDE, and we'll use aCute example to show how plugin providers can extend LSP4E and provide the final steps of a good and simple UX.
The .NET Framework provides a common language runtime and class libraries for building and running applications across platforms and languages. It includes features like garbage collection, type safety, exception handling and Just-In-Time compilation. The .NET Framework supports multiple programming languages and allows components written in different languages to interact seamlessly.
Language Server Protocol - Why the Hype?mikaelbarbero
The Language Server Protocol developed by Microsoft for Visual Studio Code is a language and IDE agnostic protocol which clearly separates language semantics from UI presentation. Language developers can implement the protocol and benefit from immediate support in all IDEs, while IDE developers, who implement the protocol get automatic support for all these languages without having to write any language-specific code. This session will let you learn more about the innards of the LSP. We will also have an overview of the current implementations in Eclipse, and outside Eclipse as well.
How to Create Your Own Product-Modeling EnvironmentTim Geisler
This document discusses how to create a product modeling environment using domain-specific languages (DSLs) and Eclipse tools. It describes using DSLs to model products tailored to a company's needs, with an Eclipse-based IDE for editing. It provides examples of DSLs used at Nokia Siemens Networks for product modeling and integration with SAP, and discusses the various components involved in creating a customized product modeling environment, including the DSL grammar/metamodel, validation, code generation, and integration with other systems.
This document provides an introduction to ASP.NET by discussing key concepts such as the .NET framework, Common Language Runtime, and Common Type System which allow for language and platform independence.

Ever since the “CloudNative revolution” took over our development environment (devenv), we have never been more challenged (or more excited). With Kubernetes, Docker (Containerd) & many other microservice-related technologies, we have a handful of technologies to master before we write the first line of code.
The document discusses native application development for Android. It covers using the Native Development Kit (NDK) to write parts of Android apps in native code like C/C++ for performance benefits. The key points are:
- Native code can provide speed improvements for tasks like signal processing but also increases complexity.
- Google's Bionic C library is used instead of glibc for size, speed and licensing reasons and has some differences like lacking C++ exceptions.
- The NDK allows building native code libraries and combining them with Java code via the Java Native Interface (JNI).
- Native code interfaces with Android via JNI and system headers while the build system handles toolchains.
The document provides an introduction to the .NET framework. It discusses that .NET is a software platform that is language-neutral and allows writing programs in any compliant language. It also describes the Common Language Runtime (CLR) which works like a virtual machine to execute code in any .NET language. The framework offers a fundamental shift to server-centric application development.
This document provides an introduction to ASP.NET and discusses key concepts related to .NET programming. It describes .NET as a framework for developing OS-platform-independent and programming-language-independent applications. It explains how .NET achieves this through the use of an intermediate language (MSIL) and a common language runtime (CLR) that allows any .NET compliant language to produce code that runs on any operating system with the .NET runtime installed. It also discusses how .NET enables web-based and distributed applications through standards like SOAP, UDDI, and WSDL.

The document provides information about internationalization (i18N) and localization (L10N). It discusses topics like what i18N and L10N are, why they are important, character encodings, locales, Unicode, and how to implement i18N in technologies like ColdFusion and Java. It also provides examples of using i18N functions and resource bundles for localization in ColdFusion applications.
Parallel builds in Eclipse IDE workspace - EclispeCon Europe 2018Mickael Istria
https://www.eclipsecon.org/europe2018/sessions/parallel-builds-eclipse-ide-workspace-value-making-and-optimal-usages
Eclipse Platform 4.8 introduced support for parallel builds in the workspace. This feature is placed at the lowest level of the workspace so it can easily be profitable to any adopter without specific adoption effort, besides respecting usual good practices. This can in theory turn the Eclipse workspace into one of the fastest polyglot build engines in developer world.
In this presentation, we’ll explain what is the value to expect from this parallel builds (mostly performance gain and faster availability of project output).
Then we’ll also get into the details of how all that is implemented, reminding ourselves some basics of dependency resolution, graph processing and scheduling rules. We’ll remind the important best practices of builders and scheduling in the Eclipse resource model that are necessary to reach best results.
And we’ll go through a few case studies of project builders to highlight how those may be improved to take advantage of parallel builds, and get into deep details of how this can be enabled in JDT and other important Eclipse projects.
After this presentation, plugin developers will be empowered to make their project builders take advantage of parallel builds in Eclipse IDE, and may get ideas about really using this feature as an alternative build engine to speed up their headless builds as well.
This document discusses parallel builds in the Eclipse IDE workspace. It describes how builds can be parallelized by creating one job per build and throttling the number of threads. Parallel builds provide benefits like shorter completion times and faster availability of individual projects. However, parallelization must account for dependencies between projects and conflicting scheduling rules used by builders. The document recommends that builders use the narrowest possible scheduling rule to minimize conflicts and allow more parallelism. It analyzes specific cases like long build chains and provides examples to illustrate how scheduling rules impact parallelization.
[EclipseCon France 2017] Eclipse Platform Generic EditorMickael Istria
The document discusses the New Generic and Extensible Code Editor for Eclipse. It describes the current state of editors in Eclipse which can be inconsistent and difficult to extend. The new editor aims to address these issues by providing a single generic editor that can be extended through plugins for different languages and features. This will improve consistency, reduce duplication and make it easier to quickly add support for new languages. The editor is demonstrated by adding syntax highlighting and editing support for new file types through simple extensions. Future plans include improving the editor framework and integrating it more fully into the IDE.

https://www.eclipsecon.org/na2014/session/integration-tests-rcp-made-easy-swtbot-and-tycho
Although we live in a modular world, it will always make sense to write and run integration-tests that allow the testing of the whole application, and not just a module. These integration-tests are often the only way to test real usage scenarios that rely on multiple modules and that can be affected by other modules and by the packaging of your application.
Some recent improvements have happened in the Eclipse world to make it easier to produce and run integration tests for RCP applications, reducing significantly their cost while keeping their coverage high, and conformance to real use-cases and ability to spot bugs. This presentation will show how SWTBot Test Recorder can be used to speed up the creation of valid integration-tests against your RCP product, and how Tycho can be used to run it easily on any existing and packaged RCP application, the same as the one your users will get.
This document provides guidance on how to contribute to Eclipse projects. It recommends contributing to projects you are interested in or depend on through documentation, user support, reporting bugs, suggesting improvements, and coding. The best ways to engage and contribute include participating in mailing lists, writing documentation on the wiki, submitting bugs and suggestions through Bugzilla, and providing code reviews through Gerrit. Following specific projects, weighing in on discussions, and submitting code for review are encouraged ways for newcomers to get involved in open source projects.
This document discusses target platforms in Eclipse and Tycho. It describes how target platforms were managed before and how the target platform concept was introduced to specify dependencies. It also covers editing and using target platforms in Eclipse and Maven builds, sharing target platforms, and some missing concepts like project-specific and compound target platforms. Performance techniques like aggregating repositories and using mirrors are presented. Related topics on sustainable repositories and linking to other repositories are also mentioned.
This document discusses new features in Eclipse 4 for developers, including using CSS in RCP applications, modeling the workbench and renderer with services, dependency injection with annotations instead of overriding classes, using the event broker for communication between components, and a compatibility layer for migrating Eclipse 3 plug-ins to Eclipse 4.
GMF Tooling provides a set of tools to configure and generate graphical editors from Ecore models. Version 2.4.0 was recently released. Improvements include a new project lead, improved documentation, and continuous integration testing. Future plans include making GMF Tooling more extensible and integrating more closely with other modeling projects. Developers are encouraged to get involved.
This document discusses principles of code generation and how they relate to compilation. It advocates applying iterative and agile principles to code generation by maintaining configuration as source code and generating code through multiple iterations. It also discusses strategies for consuming custom code within generated code without customizing all dependent code, such as leveraging underlying APIs, using the "generation-gap pattern", and customizing the generator itself as a last resort.
The document discusses modeling with Eclipse. It defines what models and metamodels are, and explains that Eclipse Modeling Framework (EMF) allows defining and manipulating models. EMF can generate Java code from models and provides editors to work with models. Various Eclipse projects like GMF and Xtext allow graphical and textual modeling and code generation from models.

How Valletta helped healthcare SaaS to transform QA and compliance to grow wi...Egor Kaleynik
This case study explores how we partnered with a mid-sized U.S. healthcare SaaS provider to help them scale from a successful pilot phase to supporting over 10,000 users—while meeting strict HIPAA compliance requirements.
Faced with slow, manual testing cycles, frequent regression bugs, and looming audit risks, their growth was at risk. Their existing QA processes couldn’t keep up with the complexity of real-time biometric data handling, and earlier automation attempts had failed due to unreliable tools and fragmented workflows.
We stepped in to deliver a full QA and DevOps transformation. Our team replaced their fragile legacy tests with Testim’s self-healing automation, integrated Postman and OWASP ZAP into Jenkins pipelines for continuous API and security validation, and leveraged AWS Device Farm for real-device, region-specific compliance testing. Custom deployment scripts gave them control over rollouts without relying on heavy CI/CD infrastructure.
The result? Test cycle times were reduced from 3 days to just 8 hours, regression bugs dropped by 40%, and they passed their first HIPAA audit without issue—unlocking faster contract signings and enabling them to expand confidently. More than just a technical upgrade, this project embedded compliance into every phase of development, proving that SaaS providers in regulated industries can scale fast and stay secure.
Exceptional Behaviors: How Frequently Are They Tested? (AST 2025)Andre Hora
Exceptions allow developers to handle error cases expected to occur infrequently. Ideally, good test suites should test both normal and exceptional behaviors to catch more bugs and avoid regressions. While current research analyzes exceptions that propagate to tests, it does not explore other exceptions that do not reach the tests. In this paper, we provide an empirical study to explore how frequently exceptional behaviors are tested in real-world systems. We consider both exceptions that propagate to tests and the ones that do not reach the tests. For this purpose, we run an instrumented version of test suites, monitor their execution, and collect information about the exceptions raised at runtime. We analyze the test suites of 25 Python systems, covering 5,372 executed methods, 17.9M calls, and 1.4M raised exceptions. We find that 21.4% of the executed methods do raise exceptions at runtime. In methods that raise exceptions, on the median, 1 in 10 calls exercise exceptional behaviors. Close to 80% of the methods that raise exceptions do so infrequently, but about 20% raise exceptions more frequently. Finally, we provide implications for researchers and practitioners. We suggest developing novel tools to support exercising exceptional behaviors and refactoring expensive try/except blocks. We also call attention to the fact that exception-raising behaviors are not necessarily “abnormal” or rare.
TestMigrationsInPy: A Dataset of Test Migrations from Unittest to Pytest (MSR...Andre Hora
Unittest and pytest are the most popular testing frameworks in Python. Overall, pytest provides some advantages, including simpler assertion, reuse of fixtures, and interoperability. Due to such benefits, multiple projects in the Python ecosystem have migrated from unittest to pytest. To facilitate the migration, pytest can also run unittest tests, thus, the migration can happen gradually over time. However, the migration can be timeconsuming and take a long time to conclude. In this context, projects would benefit from automated solutions to support the migration process. In this paper, we propose TestMigrationsInPy, a dataset of test migrations from unittest to pytest. TestMigrationsInPy contains 923 real-world migrations performed by developers. Future research proposing novel solutions to migrate frameworks in Python can rely on TestMigrationsInPy as a ground truth. Moreover, as TestMigrationsInPy includes information about the migration type (e.g., changes in assertions or fixtures), our dataset enables novel solutions to be verified effectively, for instance, from simpler assertion migrations to more complex fixture migrations. TestMigrationsInPy is publicly available at: https://github.com/altinoalvesjunior/TestMigrationsInPy.
