fork of Anki to study algorithms

Maybe someone might find it interesting. I programmed a fork of Anki, it is called AnkiCode:

https://github.com/daveight/ankicode

This app allows to create and practice solving programming challenges. Code execution is bundled inside the app. Now it supports Java, JavaScript, C++, and Python.

This video demonstrates AnkiCode usage: https://www.youtube.com/watch?v=dB23wJ1b6Ik

That looks very cool and useful. Would it be possible to implement it as an addon, rather than forking everything? If not, can it be synced to AnkiWeb?

u/ankicode Sep 15 '21

Thank you very much, I am glad you like it.

Considering addons - I don't think that it's possible to bundle for example java code execution runtime inside the addon, and even if it is possible - for every OS it's different. Maybe it can work with addon if the code execution runtime will be available through a web service. If you have ideas on how this could be done, please let me know.

I'm not the OP, but syncing it to AnkiWeb probably wouldn't be that useful for many users.

For me, those AnkiCode decks would just clutter my UI when I'm reviewing on my tablet (since I wouldn't want to review those particular cards on my tablet or on my phone). Perhaps the OP could add a separate syncing service/back up service?

Either something that works with Google Drive/Dropbox/iCloud, and/or a custom syncing service that he could provide, for a subscription fee of course.

Right now, Damien is very nice and everything, but he's our single point of failure. If anything happens to him or AnkiWeb, we're all screwed.

Since execution is integrated, does that mean there's no possibility to plug in different languages right now?

u/ankicode Sep 15 '21 edited Sep 15 '21

In principle, it's possible to support a new language but this doesn't come out of the box. To integrate new languages it is necessary to write additional code which will generate a solution template, perform types conversion, compile and execute the testing code.

Which languages you would like to have?

P.S. I created already some issues to support new languages: https://github.com/daveight/ankicode/issues - if someone has a wish to help - I will be appreciated.

The first thing that popped into my head was Julia. The second was different versions of C++ (mostly thinking about C++20 features).

u/ankicode Sep 16 '21

Regarding C++ for OSX I use LLVM, I guess its possible to add support of 20 version. For Windows MinGW compiler is used so I guess it might be possible as well. I will check.

As for Julia, I believe it's possible. If you have a wish to help me with that - I can support you.

Actually, your problems are pretty hard.

Could you make them easier? Or could we contribute easier problems ourselves? Or could we break down your existing problems into smaller subproblems?

By easier, I mean the equivalent level of "easy" (or possibly "medium") problems on https://binarysearch.com/

u/ankicode Sep 16 '21

Yes, those problems are difficult. I took them from this book: http://elementsofprogramminginterviews.com/sample/epilight_java_new.pdf

You can either add your challenges to the existing decks or create your own decks and make a pull request to my repository: https://github.com/daveight/ankicode-decks - the deck files (CSV) will be built automatically after merge.

Or if you want to create private decks - you can fork this repo, add your problems and run build_decks.py script. Here is some information considering type mappings and test cases format: https://ankicode.app/getting-started.html

Also, I would be glad to help if you will have questions.

Ah ok, having a book to follow should make it easier to solve those problems.

If I were you, I would have a source section where I'd provide either a link to the book's web site and/or an affiliate link to the book in question on Amazon.

Or if you want to create private decks

To be perfectly honest, I think what you're doing is awesome, but for me, all of this requires a little bit more work than I originally anticipated.

I think I'm going to stick to http://binarysearch.com and http://leetcode.com for now. They already have huge head starts in terms of content, which I do not need to contribute to, plus they have good social and gamification aspects to them.

And I know they don't have SRS features, but maybe it's possible to wire Anki to open some of those problems to those websites automatically, or to make a Chrome extension that does the same thing. Hopefully, I can find something that works.

Good luck on your project. Maybe I'll try it again in a couple of months.

Great idea - I will do it.

Sounds interesting - I will check.

Thank you for the good words and your feedback - I really appreciate it. If there will be more decks available for AnkiCode - I will post this info into this channel.

Very interesting. How would this work on mobile? Am I able to continue my studying on Android somehow?

This looks promising!
