Improved teardrops and curved traces

I recently read this [https://mitxela.com/projects/melting_kicad](https://mitxela.com/projects/melting_kicad) and thought I would have a go at making an equivalent EasyEDA script. The result is here: [https://github.com/mattshepcar/easyeda-round-tracks](https://github.com/mattshepcar/easyeda-round-tracks) ~~It would be nice to turn this into a proper EasyEDA extension using the javascript API but I'm not too sure on the process for reloading/debugging JS extensions with EasyEDA.~~ Edit: This is now an extension you can use directly within EasyEDA.

This looks really nice! Do you think you can port it to JavaScript in general? The extension part isn't a huge deal. You do have a simple API to load either the selected objects or the whole JSON source in javascript, do your thing, and apply either the updated json source or update the selected objects. (Of course it can get way more complex). We can help with that :) However - me not knowing very much python - porting it to JavaScript may be the harder part of this.

Thanks. It shouldn't be too hard to port it as a command line command line util I guess.. I'll give it a go and then worry about making it an extension afterwards.

@matt_1626 Well, EasyEDA runs in the Browser, so if you want seamless integration, your extension has to also run in the Browser. So it should be native JavaScript (and maybe WebAssebmbly). If you create a separate command line utility that runs on the host operating system, it may also interface with EasyEDA (e.g. as the autorouter does) but it will be a separate piece of software.

yeah I mean purely as a starting point so the code is actually written in JS and not in Python.. I can look at making it an extension after that.

@matt_1626 Okay, now I understand ;) You, you can do that. The basic script for manipulating the PCB with the API would be this: ``` js source = api('getSource','json'); // now source contains the complete JSON source of the pcb, do something with it // e.g. log it in the console: console.log(source); api('applySource',{source: source, createNew: false}); ``` You can simply run this in `Advanced` - `Ectensions` - `Run script ...` or run it in the Browsers javascript console if you e.g. install my example extension [https://github.com/xsrf/easyeda-extension-example](https://github.com/xsrf/easyeda-extension-example) or expose the api manually by executing the script `window.api = api` under `Run script ...` once. The example extension also shows how to create a simple menu and run the code via the menu, but you can concentrate on that later.

i've got it working as a node.js app now [https://github.com/mattshepcar/easyeda-scripts/tree/main/node.js](https://github.com/mattshepcar/easyeda-scripts/tree/main/node.js) The next step will be to try and run it in the browser.

I still need to add a user interface but it now works as an extension! hooray! :)

@matt_1626 wow, you're pretty fast and even used my sketchy hacks :D Btw. there is a way to load the additional javascript files using their blob-url generated by EasyEDA. Maybe they can even be directly imported with the blob url, I'm not sure... One example of fetching their content is used here: https://github.com/turbobabr/easyeda-quick-align-extension/blob/main/src/easy-fns.js#L183

Yes, your extensions were a good reference, thanks very much! I borrowed part of your readme too, i hope you don't mind. ;) I think the sketchy hack for importing different js modules is kind of ok, it's not really so different from how it looked in the node.js version except instead of "module.exports = " i have "extension.\<modulename> = "

@matt_1626 You're welcome, reuse whatever is useful ;) And you're right, it's not much different from module exports. But when I used the minified paper.js I would have preferred not having to modify the js file, but just include it. This would also remove the need to either hardcode the extension id or use the hack to get it in each file ;)

That's true. It works though and that's the main thing. :) Hopefully EasyEDA will get better support for extensions in the future and a better documented API. A built in extension registry/installer would be really nice as I think very few people even know that extensions are a thing at the minute!

I tried using this extension but for some reason it only applies teardrops to three places. I created arrays of PTHs and traces and then used the add teardrops function but it didn't apply to all of them. Does anyone know why that might be? Below is a screenshot where you can see the teardrop function only applied to a small area. Selecting all the traces or all the PTHs or both before adding teardrops did not change the outcome. Thanks. ![image.png](//image.easyeda.com/pullimage/s9I1wYd82NozVG9KFeHpOlgGrLa79CgtBcnw0cad.png)
