ace VS quickjs

I used a note system built on top of Fossil as my primary system for quite a while. Here are the details in case anyone is interested.

Fossil allows CGI extensions[1]. There's a database for tickets, but that's just a regular SQLite table that you can use to store anything you want, and it's version controlled and queryable. I stored the notes plus metadata in the tickets database. The CGI returned HTML with the Ace editor for creating/editing notes.[2] Notes were stored using the command line.[3] I needed to add the web server user to the sudoers file to access the Fossil binary.

There were two reasons to use Fossil for this. The biggest was that it handled authentication. The second is that I had a version controlled database to do all the work for me.

I think I eventually moved away from it because I prefer working locally. The "transition" was dumping the data out of the database and into markdown files.

Ace editor -> https://ace.c9.io/

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 (https://ace.c9.io/). It's a lightweight but powerful editor that includes syntax highlighting for a huge range of languages. You could also check out CodeMirror (https://codemirror.net/), which is another popular library for building web-based code editors. Good luck, and let us know how it goes!

neocities seems to use the ace editor, and you can view its default keybinds here: https://github.com/ajaxorg/ace/wiki/Default-Keyboard-Shortcuts

The frontend uses the ace editor for syntax highlighting and then sends all the "text" you have typed to a python backend. The backend then writes all the text to a temporary directory and calls the compiler using subprocess (something similar to os.system).

It is built using Reveal.js and Ace, and is a simple markdown presentation tool right in the browser.

It's a pretty complex JavaScript application but you can development and even run tests locally without ever needing to "build". I'm building a JavaScript-based text editor, too, and it also uses Makefile and you can just run a static file server such as Python SimpleHTTPServer to host all the files in the directory. I still have and componentized HTML/CSS, separated JS files.

Thanks for the suggestion! Although Ace is not the most popular kid in the block, it is still maintained. It does support tmLanguage and could be used for a proof-of-concept editor!

For the code editing you can use Ace.

It uses service workers to cache static files, by the time it opens up you already free to be offline, try toggle network switch to verify.

It has download link at bottom of the about page ([accdoo.app/about]) which you could then self host it by dropping into any static hosting services.

btw, the Pi feature was by-product from the original App but I won't expand here, if you'd like to learn more, please checkout its two Show HN post (39115559 and 39138957) previously.

Just go with quickjs, I think this is what you are looking for.

QuickJS

I think QuickJS, written in C, is a user-"friendly" starting point for implementing ECMA-262. Documentation QuickJS Javascript Engine.

There is a readme on the project's main page: https://bellard.org/quickjs/

The newsworthy bit here is that the activity seemed to have stalled for year or two and now Fabrice pushed a few fixes and made a new release.

Just to demonstrate GitHub repositories do not necessarily reflect upon a programmers' body of work, Fabrice Bellard has one (1) repository published on GitHub, quickjs. Compare the list of work on Bellard's home page https://bellard.org/.

> I am still confused, it's a JavaScript runtime intended to be deployed to JavaScript/Wasm runtimes?

Seemingly.

> Why does a JavaScript runtime need a JavaScript runtime?

Because if you want to create a Service Worker server for CloudFlare Workers and other JavaScript/Wasm runtimes, that's the only option for doing that AFAIK.

FWIW, this isn't a new idea. For example, Figma uses QuickJS (https://bellard.org/quickjs/) for their plug-in runtime: https://www.figma.com/blog/an-update-on-plugin-security/
