CodeMirror VS slate

codemirror - a code editor component for the web

massCode uses Codemirror as the basis for the editor and .tmLanguage as the grammar for syntax highlighting. This tandem opens the door to over 600 existing grammars. The application currently supports more than 160 grammars. In addition to .tmLanguage, the application supports .tmTheme for themes. There is also…

After giving up countless times since I started this project, I finally managed to dig the dark secrets of Pyodide and run pyTermTk on a browser, all of this, of course, thanks to the magic of xterm.js. I know, my friend, I know what you are thinking, I was disgusted at first picturing that hideous javascript defiling the python purity of my code, but, when I saw my red pepper shining on webkit engine, well, I couldn't hold back a tear. And after that, who am I to not include also an editor and my collection of demos and examples? So, here it is, a super minimal buggy and feature incomplete pyTermTk Sandbox

syntax highlighting is simple with https://codemirror.net/

Can CodeMirror 2 be used to highlight code from a DIV or PRE tag (without the editor)?

There sure is, take a look at Code Mirror

Codemirror is open source, so you can look at, clone and experiment with its actual code as much as you like to figure out how it works.

Developed using the LAMP stack mainly because I'm more of a back-end (PHP) dev, and for various other reasons, like affordable web servers. The front-end is vanilla JavaScript (AJAX for dynamic stuff). I also use CodeMirror to provide the visual-code editor for programmers.

- it creates a layout based on rows and cells, so it support multi-column layout - each cell can contain a different "cell-plugin", - richt-text editor based on https://github.com/ianstormtaylor/slate is built in and comes with its own plugin system. It can do weight, italic, block-types, alignment and lists and can be extended as you want (even with elements storing data and interactive components) - you can create custom cell plugins based on a schema (or custom control ui) and a component that should be rendered - it stores an object tree that represent it, not html. It therefore can contain any react component, which is great if you want to allow your editors to add interactive components or components that you already built as part of the app - i carefully optimized for SSR and bundle size, so no editor ui is rendered nor loaded. editor ui is only loaded on the client if you disable readOnly. (lazy loading) - it mainly tested with nextjs, since i used it for content-heavy pages. - its not yet tested with react-server components, but it should actually work in read-only mode

Finally there's Slate and Lexical which are super powerful in terms of customizability and extensibility. They're great options for when the editing experience plays a major role in the product.

Slate, as per its documentation, is a completely customizable framework for building rich text editors. Therefore, it doesn't offer a feature-rich text editor but instead provides tools to build one. Let's create a component called Slate and see what the Slate editor looks like.

Word of warning about Slate: I love the API and the design goals, but it appears to suffer from some fundamental issues. We were experiencing issues similar to this one and a team of multiple 10+ year experienced frontend devs couildn't figure out what was going on. I had to completely rip out a feature we had built with Slate and had to reimplement a new version from scratch with Lexical. So far we have no issues other than those inherent to rich text editing.

We're trying to choose between Lexical and Slate at work. Do you have any examples that would be similar to this? https://github.com/ianstormtaylor/slate/blob/main/site/examp...

If you are going to customise a ton of functionalities and/or implement new functionality I suggest using SlateJS. If not, have a look at Sun editor.

You definitely need to give Slate (https://github.com/ianstormtaylor/slate) a try - the best editor framework I've used.

Slate: Looks very promising, but it's for React. (Someone has floated the idea of making it framework-agnostic, but the maintainers haven't committed to that goal yet.)
