Theia is a framework to build IDEs, so you can't really 'run' Theia itself. However, you can run the example applications included in its repository. One is a browser-based IDE and the other is the Electron-based equivalent. The following instructions are for Linux and macOS. For Windows instructions click here. Prerequisites; Quick Start. Eclipse Theia - Cloud & Desktop IDE. But we can´t use Electron for it. Our goal is to display Theia still as browser content running in the. Run theia electron example by running command yarn start:electron In case of errors caused by native modules run command yarn rebuild:clean && yarn rebuild:electron and repeat previous step. Open chrome dev tools execute process.versions and verify that electron version is 11. Manually test functionalities.

Traditionally, software development has taken place on individual machines using desktop applications like the Eclipse IDE. With the rise of cloud and container technologies such as Kubernetes, the idea of coding in container workspaces, running in the cloud, has become more popular. Software development in the cloud

  • relieves the individual engineer from maintaining and setting up projects locally,

  • allows them to scale beyond the limits of their individual machines,

  • simplifies sharing and collaboration,

  • improves context switches (different projects, branches, etc.) through automation, and

  • centralizes control and confidentiality of source code.

But for the time being there are still many good reasons to prefer a locally running desktop editor, some of which are:

  • bad network connections,

  • deeper integration with local operating system features, and

  • the use of multiple different tools for different tasks (e.g. Git clients, editors, shells)

Today, every editor or IDE project either focusses on running in browsers (e.g. Eclipse Che’s IDE) or as a local desktop app (e.g. the classic Eclipse IDE). Technologies like Electron, however, allow to run the same code in the browser as well as in an integrated desktop app. Therefore, it is no longer a choice of either desktop or cloud IDE but both scenarios can be supported with a single tool.

Furthermore, since 2016 we have witnessed the rise of protocols such as the Language Server Protocol (LSP) and the Debug Adapter Protocol (DAP). They cleanly separate language specific logic that often needs to deal with internals of compilers and runtimes from the actual tool. Today we count over 50 language servers for different languages. Implementing support for such protocols within an IDE makes these assets immediately available.

Ericsson leverages Eclipse Theia to deliver user friendly cloud-first development and debugging capabilities

This is a guest post by Ericsson, an Eclipse Cloud DevTools Strategic Working Group member. Authored by Colin Grant and Kenneth Marut, Web Technology Developers at Ericsson.

When dealing with low-level code, the ability to inspect the state of memory as a program unfolds is a critical tool in a developer’s toolbox. To make that process as accessible as possible, we’ve been working at Ericsson to improve the capabilities of the Theia CPP Extension's cpp-debug-extension, and we are excited to make that work available to the open source community. This work, which we’re calling the improved ‘Memory Inspector,’ includes significant improvements to the frontend of the extension as well as a number of new features to improve the experience of viewing memory during a debug session. Developers building custom IDEs for low-level development with Eclipse Theia are welcome to try out the Memory Inspector and include it in their own products.

Cloud-based IDEs have become increasingly popular due to their operating system agnosticism, ease of setup, and flexibility. The Theia CPP Extension is built for Eclipse Theia, an open source, extensible IDE framework built with web technologies that allows users to develop custom cloud and desktop IDEs. A Theia-based IDE can run in either a desktop (using Electron) or browser environment and is ideal for creating a custom IDE tailored to a specific use case. Our work at Ericsson leverages Theia's flexibility by allowing us to deploy a desktop application to meet current needs while planning for a cloud-first future of work primarily in the browser. We have been building the next-generation IDE for our C developers, providing them with a modern user-interface, convenient wrappers around custom tooling, and an overall updated workflow so they can be more productive and effective in a world where remote work and distributed teams are increasingly common.

One important area of focus for us is improving the debugging experience. Our users had been dissatisfied with the cpp-debug extension’s existing memory viewer, naturally comparing it to the legacy memory viewer available in the Eclipse IDE. As we received more user feedback regarding the memory viewer, and after several weeks of design and implementation, we released the Memory Inspector internally, designed with Theia's goals of extensibility and adherence to open-source standards in mind.

By default, the Memory Inspector depends on the requests built into the Debug Adapter Protocol and is compatible with any debug adapter that implements a ReadMemory request, but it allows adopters to substitute any memory providing mechanism desired. It is built with several use cases already in mind, including displaying memory, viewing registers, and comparing memory from different regions or different points in time; it also includes a UI for writing memory values, for debug adapters that support a custom WriteMemory request ahead of that request's addition to the Debug Adapter specification. Adopters can easily extend these classes and customize the behavior to suit their use cases and the specific capabilities of their chosen debug adapter.

The list below highlights some of the primary improvements provided by the Memory Inspector:

More entry points for viewing memory during a debug session

Theia

Create a new memory view during a debug session by right-clicking inside the debugger pane’s Variable tree view.

Alternatively, generate a new memory by clicking on the Create New Memory View icon in the toolbar, and manually specify an address.

Dynamic updating views while advancing the debugger

Memory views are now dynamic and will update as you step through code. Memory locations that have changed from one frame to the next will be highlighted.

Click here for full size image.

Improved settings and configuration

Memory views now have editable titles for better organization. Additionally, each view will populate a list of recently viewed addresses for easily swapping between locations. Views also can now be ‘locked’ in time, preventing dynamic updates (this may be useful for comparing a single memory address at separate times).

Inspect memory values on-hover

Eclipse Theia Download

Improving on Simon Marchi’s work in this pull request, we have added and improved the ability to show colorized variable values in-line with memory addresses (high contrast theme also added). A custom hover renderer displays different representations (radices) when hovering over values.

Support of multiple memory views

Spawn any number of memory views, independent of each other and drag/drop them to anywhere inside of the application window.

Memory views can now be ‘diffed’, allowing you to compare memory at different addresses and/or different times.

We are excited to make the Memory Inspector available to the Eclipse Theia community, and hope that it will benefit others building IDEs for low-level development. With the future in mind, debugging memory using Theia may soon have an edge over other IDEs by encouraging and enabling collaborative memory debugging and workspace sharing. The pull request for the Memory Inspector can be found here with step-by-step setup instructions. We encourage anyone who may be interested to try it out and submit any comments, questions, or feedback via GitHub.
