  • Show HN: Heynote – A Dedicated Scratchpad for Developers
    Performance is mostly handled by CodeMirror (, the underlying editor that Heynote is built upon. It seems to handle quite large buffers well. Where I have seen some minor performance issues is when working with very large blocks in certain language modes. - Source: Hacker News / 5 months ago
  • Building interactive tutorials with WebContainers
    We'll use some innovative technologies, including WebContainers, CodeMirror, and XTerm, to build this. If you're not familiar with these, don't worry, we'll cover them all during the process. - Source: / 6 months ago
  • Racket branch of Chez Scheme merging with mainline Chez Scheme
    I don’t think the arrows are possible with VScode? Someone said they might be possible with CodeMirror (Just in general - not specifically for racket- I’d love to see this for rust and elixir). - Source: Hacker News / 7 months ago
  • Our Code Editor is open source
    I don't see them on the list of sponsors for the CodeMirror project, but I hope they dedicate some funds for it. - Source: Hacker News / 11 months ago
  • JSF 2.0 AJAX: Call a bean method from javascript with jsf.ajax.request (or some other way)
    Some background: I am building a custom JSF component. The component is basically a text editor and it should have a "Save" -button for saving the content string of the editor. As I am using the CodeMirror library, I need to fetch the content (string) from the editor with javascript and send that to the server. Therefore, in this case I cannot use XML-based JS invocation such as f:ajax. Source: 11 months ago
  • Created a simple online JavaScript Playground, it's a place for you to try out your code and ideas.
    Thanks u/OutlandishnessKey953, the playground built with React, Docusaurus(, CodeMirror(, Sucrase(, etc. Source: 11 months ago
  • Is it possible to create a textarea with automatic syntax highlightning where the user can write commands (sql)?
    Unfortunately NiceGUI does not yet have a ready-made code editor ui element. But it should not be too hard to create it. Maybe based on the popular Vue3 component? We have an example showing how to adopt custom vue components in the repo. You could either do it directly in your project or create a pull-request to have it integrated into the NiceGUI core. We would be eager to see you and... Source: about 1 year ago
  • Making script files editable on web
    CodeMirror would be an example for a web-based code editor. Source: about 1 year ago
  • Writing a (simple) code editor for the web?
    Hey there! Thanks for reaching out. Writing a code editor with syntax highlighting in a browser can be a little tricky, but it's definitely doable. One resource that might be helpful is the Ace Editor library ( It's a lightweight but powerful editor that includes syntax highlighting for a huge range of languages. You could also check out CodeMirror (, which is another... Source: about 1 year ago
  • Writing a (simple) code editor for the web?
    If it's the latter, I would suggest CodeMirror. It's very easy to set up, modular and supports syntax highlighting, lots of keybinds, emmet, ... Source: about 1 year ago
  • What is the proper language markup type we should use for a MakeFile code snippet?
    Alternatively, you can use the cm-editor-syntax-highlight-obsidian plugin which allows syntax highlighting for code blocks in the editor using CodeMirror which also supports GNUMake syntax highlighting. Source: about 1 year ago
  • Create a Business Language for a Rails Application
    I had a Rails app, between 2006-2018, where I created a DSL for end-users to specify report specifications. The report "Spec" language lexer/parser used techniques in Marc-André Cournoyer's book "How To Create You Own Freaking Awesome Programming Language". In addition to the new language grammer, it also supported in-line SQL where clauses, and Excel formulas. The GUI was a codemirror-backed editor with syntax... Source: over 1 year ago
  • Creating a Custom Language Code Editor Using React
    In order to achieve this, we started researching potential solutions and found Code Mirror. - Source: / over 1 year ago
  • The ShnooTalk programming language
    Of course you can just use the UI elements and use a different editor like code mirror or monaco, and rewrite the backend to your liking. Source: over 1 year ago
  • Innovative Rich Text Editing: Typing Affinity
    I've spent a lot of time reading through these codebases and found that reading very useful. - - Source: Hacker News / over 1 year ago
  • Ask HN: How to write a rich text editor?
    Https:// A toolkit for building rich-text editors on the web ProseMirror was written by Marijn Haverbeke, who also wrote (and rewrote!) the much used [CodeMirror] editor. So the design of his "editor toolkits" are based on years of experience developing and maintaining text editors. Marijn is very responsive on all the respective discussion boards. Examples, including markdown:... - Source: Hacker News / over 1 year ago
  • Editable/Runnable Python In StackOverflow
    Hi Python People! Just wanted to share that I made a way to add runnable and editable Python to your StackOverflow Questions and Answers! The "brains" of the project is Pyodide, the "face" is CodeMirror, and what is in between (the skull?) is what I did. Hope this is useful to you! Source: over 1 year ago
  • Show HN: Make 3D art in your browser using Lisp and math
    It's CodeMirror! All I had to do was write a Janet grammar for it -- very easy to do. CodeMirror is pretty amazing -- I was able to implement the "edit values with your mouse" by just asking CodeMirror for the syntax node under the cursor, checking if it parsed as a number, and if so replacing it with a different string. I went with... - Source: Hacker News / over 1 year ago
  • Show HN: Make 3D art in your browser using Lisp and math
    I'm using as the editor, and I'm basically just running an onchange event on every keystroke. Not very fancy or sophisticated. The details of what exactly happens in that event are very specific to WASM/Janet/Bauble, but I think you could do something similar with JavaScript code pretty trivially. Long-term I think I'd rather break this out into a separate page with multiple canvases inline... - Source: Hacker News / over 1 year ago
