Hi Guys! For the past couple of weeks, I was working on a new Code Editor for Competitive Programmers. Today, I am happy to present it to you all, the first release of CP Editor.

But First, Why we need a new editor?

There exists so many code editor of all types, written in all languages but all of them are tailored down for Development of Software and none is specially focused for Competitive Programming. As competitive Programmers, we need our Editor to be Fast, Reliable and Something that just works. We focus mostly on correctness of our code and this involves compiling and re-running on sample test cases again and again.

CP Editor is Fast written in Native C++ (Qt), Cross-platform (works everywhere), and has all basic features that a competitive programmer needs from an editor. CP Editor takes away your responsibility of compiling the code and running it on your sample test cases. It automatically with just one click or keystroke compiles and runs your program and gives back to you the output.

Features
  • Code formatting with clang-format or any other tool of your choice.
  • Auto-parenthesis, Word Wraps, auto-indentation and all other basic editor features.
  • Syntax highlighting for C/C++
  • Dark theme for the code editor
Limitations
  • No support for language other than C/C++ (Sorry Python and Java users, I will try to add these languages ASAP)
  • No Auto-complete or Intelli-sense (It makes things slower, learn to remember stuff don't rely on LS too much).
  • Highlighting of Closed and its corresponding Open braces is not working. (I am working on it).
Installation
  • For Windows, you can get the Installer file from here. Install it just as you do with other software.
  • For Linux, you can download and run the Editor on any distribution with AppImages. Get it here

This is a code editor and does not come with any Compiler bundled.

So you will need mingW-gcc or clang or msvc on your PATH.

As with every great software, this Editor also comes with all its code open-sourced and you can verify for yourself that your code remains on your machine and never goes anywhere.

The project is available at https://github.com/coder3101/cp-editor2

For complete instructions, setup queries and other issues please refer to the above URL.

Happy Coding !!!

EDIT

If you face any issue regarding VCRUNTIME140_1.DLL MISSING.

Please Install Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 for your system.

Great Software Bruh! Loved it. Its easy to use and also lightweight. Takes less time to compile and run. Dark Mode is awesome. More than two input files can run together and in just a very few seconds, we can see the output as well. From today onwards, I will use this software to write codes for cp questions.

Hi! I installed the precompiled setup for Windows but I am having trouble running it.

After installing when I first tried to run CP-Editor, an error message popped up saying

VCRUNTIME140_1.dll is missing.

I downloaded the DLL file but now it shows a different error -

The procedure entry point __CxxFrameHandler4 could not be located in the dynamic link library.

Please fix.

I have not used the app however there's a suggestion from my side to use single key for run(maybe F10) and compile & run(F9). Small improvement but makes a huge diff.

    In some future release I will provide a way to customize the shortcut keys. But Even having F10 or F5 still requires pressing Fn Keys. In most of the newer laptop the Function keys by default perform operations like volume Up, brightness and stuff, unless the behavior is changed from BIOS.

    I thought if it needs 2 keys anyways, why not make it easy to reach key like Ctrl+R to run.

    First you need to have a compiler installed. Install mingW-gcc. Then add it to your PATH (Environment variable). To verify if everything went well open a command prompt and run g++ --version it should return the version. Now go to editor setting and write compile command like g++ -Wall and now you should be able to compile.

    As for format command leave it default and run command also can be left as default.

    Note Incase you already had DevCpp installed. You most likely have g++ installed. Simply navigate to the directory you installed DevCpp and inside of it you should find a directory named mingw, add this mingw/bin to environment variable and everything should work.

    In a nutshell add any C++ compiler to your environment PATH.

Very good IDE for competitive programming purposes, but please implement some form of variable autocomplete. When upsolving I like to use long, descriptive variable names, and autocomplete is very useful.

            It seems that you need to upgrade to Ubuntu Disco or Eoan. Otherwise you won't have the required libc version.

    Are you using a Cross compiler. The gcc or compiler you have used in compile command is most likely to be old and is producing 16 bit binaries. Use a different compiler the one compatible with your system.

      My compiler is called "GNU GCC Compiler" as in Code::Blocks 17.12. I've been using this compiler at Code::Blocks and it works fine (assume that it means my compiler is compatible with my system).

      I think the problem may be my compile command: g++ -Wall -fexceptions -g -O3 -std=c++14 -c. I'm not familiar with writing compile commands, since Code::Blocks automates it, so I think that there's something wrong with my compile command.

      For reference, I'm using a 64-bit Windows 7 Professional.

          So I tested the editor on another code today, and the error above no longer shows up. Instead I saw this at the Compiler Messages:

          [09:32:43] [Runner[1]] [Error occurred during execution on first testcase]

          right after I run my code. The same error occurred for all the inputs I've specified. I've then changed my compile command into g++ -Wall but that doesn't seem to change anything.

          Is there a way I can reset all the settings other than uninstalling and reinstalling the editor?

            There will be a file in your home directory (in case of windows : C:/Users/your_name) named cp_editor_settings.ini. Delete it or you can also reset all settings from Help => Reset Settings

            If problem persist, try disabling your Antivirus which maybe preventing your executable from running. For that check to C:/Users/name/AppData/Local/Temp directory a file named a.exe, if it exists try running it by double clicking it, does it starts. (a.exe will exist only after compilation was okay)

            1. I was suggesting you try setting the path to your Clang Format executable file in "Clang Format Command".

            2. Have you got this warning: "Code formatting failed to work. Please check whether the clang-format binary is in the PATH and the style is valid."?

            3. Can you run exactly clang-format --version in the terminal to get the version of Clang Format?

            4. Can you use Clang Format in the terminal to format a file in no more than 2 seconds?

    Large input to stdin?. As for stopping compilation if an compilation was active and you again press compile button. The old would get killed a new would start. Making sure that editor only executes one compiler process at a time. Yes, a button to killing a running executable would be nice. I already added a killtimer. So if your process hang up. Say in some infinite loop. The editor will kill the process after 5 sec. (It doesn't seem to work on windows but works on my linux)

    2. 1<<32 will cause overflow because 1 is an int literal, $$$2^{32}$$$ is out of the range of int.

    Settings up CF tool is easy. Just add CF tool to PATH and if you were able to submit from command line using CF submit, You should be able to submit using editor as well. cf parse and cf race are not supported yet. We do plan to release YouTube videos as tutorials but we have some more work to do in improving editor now. Meanwhile you can ask all your queries at our telegram group ( @cpeditor )

    For competitive companion, go to chrome extensions and add it. Set the port to 10045 in extension options of competitive companion.

    For CF Tool, download latest zip and extract. Now move the file to the PATH by typing sudo mv cf ~/usr/bin on the terminal. Be sure to be in the directory of cf by cd.
    Now in the terminal, type cf config, 0: to login, 1:add template.
    In template, after selecting the language,just enter the path to your default code. just type the other suffixes, press enter in the optional stuff and write the path to your .exe or a.out of your default code.

    after this u are good to go and submit through CP EDITOR!!

    That functionality is not added yet. Instead you can set a big font size for the time being.

snapdragon3101 I added the path "/usr/bin/clang++-10" after installing clang by the command 'sudo apt install clang' on Ubuntu 20.04 Now this error pops up in the Binary Formatter on the right. Can you please suggest me how to fix this.

clang: error: unsupported option '--cursor=360' clang: error: unsupported option '--style=file' ]

      snapdragon3101 Can you tell me the details like put clang-format but, where in the path or style. And if you meant to include a file named 'clang-format' then where do I find that, because I can only see these five executables in my \usr\bin directory clang clang++ clang++-10 clang-10 clang-cpp-10

        Short answer: sudo apt install clang-format-10 and put clang-format-10 in Clang Format->Path in the Preferences.

        Other details:

        1. clang++ is the compiler, not the formatter.
        2. Though the name of that setting is "Path", you only need to make sure that you can run it in the terminal, so if it's in the PATH, you don't need to put the complete path.
        3. I'm not using Ubuntu so I'm not sure, but perhaps clang-format is not included in the clang package on Ubuntu.

    Seems like you had out some invalid configuration in .clang-format style: Reset that settings to default and check back again.
