Open Source JavaScript Text Editors

Microsoft’s vscode source code is open source (MIT-licensed), but the product available for download (Visual Studio Code) is licensed under this not-FLOSS license and contains telemetry/tracking. The VSCodium project exists so that you don’t have to download+build from source. This project includes special build scripts that clone Microsoft’s vscode repo, run the build commands, and upload the resulting binaries for you to GitHub releases. These binaries are licensed under the MIT license. Telemetry is disabled. If you want to build from source yourself, head over to Microsoft’s vscode repo and follow their instructions. VSCodium exists to make it easier to get the latest version of MIT-licensed VSCode. Please note that some Visual Studio Code extensions have licenses that restrict their use to the official Visual Studio Code builds and therefore do not work with VSCodium.

CloudBeamer is a Cloud application which supports the creation of LaTeX presentations with the Beamer package. It allows you to edit and compile your LaTeX presentations online, without having to install anything. CloudBeamer adds the flexibility of seeing your slides compiled as you type without having to compile the entire presentation first, along with the option of exporting the presentation as an HTML5 page which shows the slides as if they where on the faces of a cube. Actually this feature, which appears in the editor too, is only supported by Google Chrome browser. This development project is intended to design new features for CloudBeamer and has so far reached the goal of adding Cloud Storage for presentations and images contained within them. This feature is designed in a modular way, which will allow in the near future to support other Cloud storage platforms than the one which is actually avaliable (Dropbox).
