Hightail — automatic tester for programming contests Hi! In this post I would like to introduce you to an application called [Hightail](http://github.com/dj3500/hightail). [Hightail](http://github.com/dj3500/hightail) is an automatic tester for programming contests such as CodeForces rounds. It will parse the problem statement, extract sample test cases (inputs and outputs) from it, and verify the correctness of your program against them. It is built to provide maximum automation and to relieve the contestant as much as possible. A list of Hightail's features: - parsing problem statements - parsing entire contests (autoloading all problems) - scheduling contest parsing ahead of time - ability to comfortably view, edit and add test cases - handling of all verdicts: WA, TLE, RE, even AC - customizable time limits - ability to create in/out files in your working directory - detection of floating point values (comparing 0.1 vs. 0.10 does not give WA) - easy-to-use UI, keyboard shortcuts - resilient: it is multi-threaded so ...

CFBooster: A tool to help grab first bloods Hello Codeforces! It's a new decade already and I decided to write a tool to help me grab first bloods faster in Codeforces rounds, and I made it open-source _[since the Codeforces rules say so](https://codeforces.com/blog/entry/8790)_. Everyone knows to grab first bloods faster, you need to write code and test samples with lightning speed. There's [Hightail](https://codeforces.com/blog/entry/13141) over there already but still, it's not the most comfortable tool for me to use. So... (loud music) here comes my new tool CFBooster! You can click [this link in github](https://github.com/fjzzq2002/CFBooster) to download it. Basically, it will help you test inputs & outputs right inside your program and can even help you write some codes for input. I'm too lazy to repeat it all again since there's a README in the above link there already. You can see an image of it in action by clicking [here](https://raw.githubusercontent.com/fjzzq2002/CFBooster/master/sample.gif) (sadly I cannot ...

Competitive Companion — Parse problems from the browser Hi! After releasing [CHelper Companion](http://codeforces.com/blog/entry/56275) as an alternative to the original CHelper extension six months ago, development has been ongoing and CHelper Companion has "evolved" into [Competitive Companion](https://github.com/jmerle/competitive-companion). Competitive Companion is a browser extension for [Chrome](https://chrome.google.com/webstore/detail/chelper-companion/cjnmckjndlpiamhfimnnjmnckgghkjbl) and [Firefox](https://addons.mozilla.org/en-US/firefox/addon/competitive-companion/) that can parse problems and contests and extract the useful data. This includes things like time/memory constraints and sample test cases. While CHelper Companion was only capable of sending this data to CHelper, Competitive Companion works with pretty much all popular tools. Next to that, Competitive Companion is also capable of sending the data to your private tools, without requiring a complex setup. Using it is very simple. Just install the extension, make ...

Google Chrome extension for automatic sample case testing on Codeforces Hello all, I'd like to share with you a google chrome extension called [Sample Case Tester](https://chrome.google.com/webstore/detail/sample-case-tester/dmjempfpjamhmpjmhgadajdogngacegg). Like the name says, it helps you in easily testing your code against the given sample cases for any problem, both in a contest and in practice. It adds an editor to the problem page where you need to just paste your code and run it to see if your code passes the given sample cases for that problem or not.  If your program is giving wrong output for one or more of the sample cases, it'll show you that case along with your program's output and also the expected output. If there are any compilation or runtime errors, it'll show those as well. And ofcourse, if your program gives the right output for all the cases, it'll tell you that your code passed! ![ ](https:/...

HAC: Helper for Algorithm Competitions **hac 1.0.5 released (2015-10-16)** **hac** is a command-line tool that: - prepares source-code templates, - downloads test-cases, - evaluates solution against test-cases. **hac** is highly extensible and configurable, it has it's own plugin system that dynamically discovers: - site-processors (Python files for handling sites like Codeforces), - programming language and "runner" (e.g. shell script) templates. ### Links - [Homepage](https://github.com/plesiv/hac) - [Installation](https://github.com/plesiv/hac#install) - [Usage](https://github.com/plesiv/hac#usage) ### Acknowledgement I was inspired to write **hac** by previous work of some other people [1] [2] [3] [4] [5]. I would like to thank those people as well as everyone else invested in the Codeforces community (admins, contest-organizers)! <3 [1] http://codeforces.com/blog/entry/15871 [2] http://codeforces.com/blog/entry/10416 [3] https://github.com/lovrop/codeforces-scraper [4] https...

Hightail automatic tester (CPP) for programming contests running issues. I tried running Hightail as mentioned [here](https://github.com/dj3500/hightail)... 1) I downloaded the .jar file 2) As I had JDK installed I simply opened .jar file with Java(TM) Platform SE binary First time a welcome message showed up saying "This config file couldn't be loaded( probably because this is first run ). A new config file will be created and you'll be taken to the settings" On clicking "OK" the following error message showed up &mdash; "The configuration file could not be created. Make sure that Hightail has write rights to its directory" Hightail version &mdash; Hightail-v0.9.7 OS &mdash; windows 10 I tried making some changes into properties but all in vain. I'd really appreciate any help to get this up and running.

ACHelper — Another Contest Helper Let me introduce the competitive programming tool that's aimed to help you get AC more easily: **ACHelper**, [wiki](https://github.com/AlCash07/ACHelper/wiki) I tried to take the best elements from [Hightail](http://codeforces.com/blog/entry/13141), [CHelper](http://codeforces.com/blog/entry/18974) and [Caide](http://codeforces.com/blog/entry/18838), and add project generation using CMake on top of that. The tool itself is cross-platform and should work with any programming language and IDE that is supported by CMake (or other project generator). However, templates **only for C++ for Mac** (that should work for Linux as well) are implemented at the moment. Any help on Windows support is highly appreciated, more details on that [here](https://github.com/AlCash07/ACHelper/wiki/How-to-contribute). A [screenshot](http://i.imgur.com/u1aneUm.png) of ACHelper with my AppCode IDE after the testing.  Let me know what you think.

A Codeforces Testing Framework for cpp and terminal users ;) Hi all, Recently I have written some small scripts which can parse a Codeforces contest, download all the sample cases and auto-test your code. Basically it's doing the same thing with [Hightail](http://codeforces.com/blog/entry/13141) but it's specialized to terminal and cpp users and much more light-weighted. You can find the project [here](https://github.com/orzzzl/codeforces-autotesting-script). And you can refer to the [README files](https://github.com/orzzzl/codeforces-autotesting-script/blob/master/README.md) for instruction of how to use it. Thanks.
