    VSCodium

    VSCodium

    binary releases of VS Code without MS branding/telemetry/licensing

    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.

    CopyTranslator

    CopyTranslator

    Foreign language reading and translation assistant

    Copy-and-translate foreign language assisted reading and translation solution. Just copy the text to the clipboard, you can view the translation results in the next second. Solve the problem of garbled codes caused by redundant sentence breaks and line breaks, and the translation results are more in line with reading habits. Infinitely close to the system-level open source implementation of translating, drag and drop to select and copy the translation. With the update of CopyTranslator, the functions are constantly enriched, and the differences between different versions are gradually significant. Therefore, the user guides of different versions are separate. CopyTranslator monitors the clipboard changes, processes the clipboard content (such as removing redundant line breaks, etc.), and displays the translation results. Compared with copying and pasting directly to the web version, the translation effect is greatly improved.

    Inkdown

    Inkdown

    A WYSIWYG Markdown editor, improve reading and editing experience

    Inkdown (bluestone) is a Markdown reading, editing, and sharing tool. Almost fully compatible with the GitHub Flavored Markdown standard, while extending the Mermaid graphics and Katex formula, supporting light and dark styles, and somewhat different from other WYSIWYG editors, Inkdown does not pursue complete customization. Its core goal is comfortable reading, smooth editing of Markdown, and document sharing in the simplest way possible. As a document publisher, markdown source code mode is undoubtedly efficient and free, but as a note, it is not conducive to reading. The table element of markdown is not conducive to writing, and the double-column mode is not conducive to focusing, so the Inkdown Editor was developed. It combines rich text with markdown editing habits to help you record daily, and saves it in standard markdown format, which allows your notes to be used anywhere and backed up in any way.

For the purposes of versioning, any changes that break any of the endpoints or APIs documented here will be considered semver-major breaking changes. Undocumented library internals may change between minor versions, and previous APIs may be deprecated (but not removed). The minimum supported TypeScript version of the included typings is 3.9; for use in earlier versions you may need to set skipLibCheck: true in your config.

    ngx-quill

    ngx-quill

    Angular components for the Quill Rich Text Editor

    ngx-quill is an angular (>=2) module for the Quill Rich Text Editor containing all components you need. It is possible to set custom default modules and Quill config options with the import of the QuillModule.forRoot(). Use <quill-editor></quill-editor> in your templates to add a default quill editor. Do not forget to include quill + theme CSS in your build process, module or index.html! For builds with angular-cli >=6 only add quilljs to your scripts or scripts section of angular.json, if you need it as a global. In most cases, a WYSIWYG editor is used in the back office to store the content to the database. On the other side, this value should be used, to show the content to the end user. In general, QuillJS recommends using a QuillJS instance to present your content. Just create a quill editor without a toolbar and in read-only mode. With some simple CSS lines you can remove the default border around the content.
