Great idea, I released an update which adds the keyboard shortcut Ctrl+Shift+U to parse problems/contests, it should be available in a few minutes. Whenever the green plus icon is visible, that shortcut will work too.

I'm assuming you are seeing a blue bar, not a green one (because if it's green, it's probably not from my extension).

When you see that bar, it is retrieving all the problems and extracting the useful data out of all of them, after which it sends them to one of the supported tools.

To make use of this extracted data, you need to do one of the following:
- Use one of the supported tools (see the post to see which one are supported).
- Add support for the extension to your tool, which requires quite a bit more work. Instructions on how to do that can be found here.

If you need help with getting up and running using one of the supported tools, please tell me which one you are using so I can give more specific instructions.

If anybody runs into similar problem, it was somehow because my Intellij ended up with "Build project automatically" unchecked. I followed steps here and now everything works great, thanks for the tremendous plugin!

Unfortunately, LeetCode cannot be added. This is because LeetCode forces solutions to be written in a pre-defined method with a pre-defined signature (method parameters and return type), which is something that Competitive Companion does not support. The chances of it being implemented in the future is pretty low, considering how none of the publically available tools that Competitive Companion sends data to are capable of handling such constraints at the moment.

Besides that, LeetCode doesn't seem to have any structure in their problem descriptions, which makes it pretty much impossible to parse something like the sample testcases.

I have just released version 2.5.0 which adds a problem parser for Virtual Judge. Your browser should auto-update within 24 hours.

Unfortunately, I could not find a way to parse all problems in a contests at once due to how Virtual Judge renders contest problems dynamically. You can however parse all problems in a contest separately, just like how you would parse out-of-contest problems.

It's also worth noting that while the problem parser can parse the sample testcases for a lot of problems, it will not work correctly for all of them. This is because Virtual Judge does not have a standarized format for problem descriptions, so the extension has to look for signs of sample testcases like <pre> and <span style="font-family: some-monospace-font;"> tags. This isn't a rock-solid solution, but it works for the majority of the problems. Feel free to create an issue on GitHub when you find a problem that isn't parsed correctly.

Thanks for the suggestion, but I'm not planning on changing this. I think "AThreatreSquare" is better than "1A" when you're participating in a contest with multiple problems. Especially when having to differentiate between different problems having the full name instead of just the letter can be very helpful.

I am not very good at making videos, and I think this paragraph in my post already explains how the extension works pretty clearly:

"Using it is very simple. Just install the extension, make sure you got one of the supported tools open, navigate to a problem page and click on the green plus icon in the top-left of your browser. On websites where Competitive Companion is able to parse contests, navigating to the page with all the problems and clicking on the green plus icon will download and parse all problems in the contest at once. You can also use the shortcut Ctrl+Shift+U instead of the green plus icon."

I did, however, record a short video two years ago for a PR I made to add Competitive Companion support to Hightail: https://www.youtube.com/watch?v=LnI4HuzWY18 for PR #107.

I have just fixed the USACO Training issue you mentioned. I'll look into the UVa issue later this week because UVa seems to be down right now, and I'll publish a new release once that's done.

That's odd, I released 2.17.2 about a week ago to make the extension work with the Facebook Coding Competitions platform with the upcoming Qualification Round you linked. When I released it everything seemed to work fine on archived problems, so either the live problems are displayed somewhat differently or the platform as a whole got some last-minute updates in preparation of the Qualification Round.

Either way, I am on vacation right now so I'll have a look at it at the beginning of next week.

You're right, I forgot to change that when I switched it from fileName to pattern (I removed the regex type 1.5 years ago). This is fixed in 4904656 which will be released in the next few days.

Hmm, yeah, I seem to have snuck in a breaking change in 2.18.0 when I re-added the regex input type after it being gone for 1.5 years. It is used when parsing FHC problems because depending on what stage you're in the filename of the input file changes (problem_name_validation_input.txt -> problem_name_input.txt).

Although I try to avoid breaking changes (this is the first one in over 2 years as far as I can tell), in this case I'm going to let it stay because most tools seem to play well with the regex input type already (CHelper, JHelper, my own private tool, acmX, CP Editor, basically any tool except for Caide).

Because I don't know if Caide will be patched soon, the best solution for Caide users would be to manually install version 2.17.4 and to manually update the filename when needed to.

Please send me the links of the Codeforces contest page and the CodeChef problem page you tried to parse.

Competitive Companion only parses problems and sends the extracted data to external tools like CHelper, JHelper, Hightail, acmX and others. If you don't have a tool that listens for Competitive Companion data running, then clicking on the + button does nothing.

Because it's not clear from your comment whether you are already using a tool which listens for Competitive Companion data:
- If you are using such a tool and nothing happens when you press on the + button, send a bug report to the developer of the tool you're using.
- If you are not using such a tool you'll have to start using one if you want to make use of Competitive Companion. For Sublime Text the combination of FastOlympicCoding and FastOlympicCodingHook should work (note that neither of those tools are made by me so I can't provide support for them).

At the moment I don't think there are vim specific tools, although you could try IDE-agnostic tools like Caide or Hightail. You could also create your own tool which is documented here (for inspiration you can watch the first ~12 minutes of ecnerwala's Google Kickstart 2020 Round E video in which he explains his setup, which includes vim and Competitive Companion).

Thanks for reporting the issue! I have just released version 2.18.3 which fixes this bug, it is already available for Firefox and is pending review on the Chrome Web Store.

This won't happen. I don't own any Apple devices (apart from a very old iPod Touch 4), so I can't meet Apple's requirements regarding packaging and distributing Safari extensions.

I created a parser for TLX/TOKI and sent a pull request: https://github.com/jmerle/competitive-companion/pull/122

Competitive Companion only parses problems and sends the extracted data to external tools like CHelper, JHelper, Hightail, acmX and others. If you don't have a tool that listens for Competitive Companion data running, then clicking on the + button does nothing.

As far as tools go, at the moment I believe the only Sublime Text-specific tool is FastOlympicCoding together with FastOlympicCodingHook. You could also try one of the IDE-agnostic tools like Hightail, caide and egor. Please note that I did not create any of these tools, if you need help with them you'll have to contact their developer(s).
