Hi Guys!

CP Editor met Competitive Companion in 3.0, giving it the ability to parse contests from over 30+ online competitive programming websites. Now, with CP Editor 5.0, it met CF tools, a wonderful tool by xalanq which can do all most everything in code-forces, even submit solutions. Read more about CF tools in his blog.

If you are a pro-user and like vim keybindings, using cf-tools on your favorite terminal with tmux would give your more than what CP Editor has to offer but at the same time, it is very time consuming and difficult to setup on windows.

Let's dive into what is new for us in CP Editor 5.0

Submit solution to Codeforces from CP Editor, you don't need to copy or upload your solutions manually. Let CP Editor do it for you with just one button click. This feature requires that you have cf-tools installed and you have correctly configured cf-tools. Read the instructions below on how to install and setup cf-tools. Please note the submit button will be only visible in the editor if the problem was parsed by Competitive Companion from code-forces.

Installation and setup of cf-tool

First download the zip file which contains CF-tool. It will be one single file with no dll or dependencies. You can download it from https://github.com/xalanq/cf-tool/releases
Now you need to add it to your SYSTEM ENVIRONMENT PATH. Here is how I prefer to add it. First Create a new directory in your Home directory (in windows C:\Users\<name>) named bin, and copy cf to that directory. Now your cf is located in ~/bin/cf (in unix) or C:\\Users\\bin\cf.exe (in windows). Add this directory to your PATH just like normal. Alternatively, UNIX users can directly copy cf to /usr/local/bin
Verify if you added it to your PATH correctly by opening a new terminal or command window and typing cf --version. If you get the version proceed to next step, else go to step 2 and follow (re)carefully.
Now you need to login to code-forces using cf tools. In a command window type cf config and then choose type 0 (username and password). Enter your username and password of code-forces. If everything goes well, cf tool will say login succeeded!
Now you need to set templates in cf tools. In our case templates will decide which code-forces language to choose when doing a submission (there are many C++ compiler, which to use? when uploading .cpp file). Follow the given steps below to add a template to cf tools (in this case Python). You may need to do add up to 3 templates for each language. If however are sure you will never use java then you can skip addition of java template.
5.1 Open a command window or terminal.
5.2 Type cf config
5.3 Choose index 1 (add template)
5.4 Select a language index (this is the language you want to submit on codeforces with, 31 for python3)
5.5 Now cf tool will ask for any template for selected language.
5.6 Type in an absolute PATH to any file with language extension. (It must have .py extension in this case)
5.7 Now it ask other suffix. Keep it empty
5.8 Now it will ask for Template alias. Type in extension of language (py in this case)
5.9 Now it asks before script. Keep it empty
5.10 Now it asks script. Type anything (say "dummy" in this case)
5.11 Not it asks after script. Keep it empty
5.12 Make it default (NO)
You should repeat step 5.1 to 5.12 for other language as well. Make sure that you change the file extension in 5.8 and file in 5.6 (It can be an empty file but must be one of .cpp or .py or .java extension depending upon language for which you are adding template)
Now nothing is needed, yes make sure to reboot or sign out for updated PATH variable to be visible to CP Editor. Make sure you don't create two different templates for same language, if you did so by mistake please delete one with cf config -> remove template.

Set up snippets of codes like Sublime Text, You can add as many snippets as you want in all 3 officially supported languages in CP Editor. You can set up hotkeys for triggering snippets and then search for your snippets and paste it into text editor. You can even rename snippets. Snippets are language defined, you won't find C++ Snippets when your Tab language is set to Python. All snippets are stored inside cp_editor_settings.ini file, which is located in your home directory and contains all the settings of CP Editor. This also, portable and platform independent. In order to inspect it, you can open it like any normal text file.

Big Thanks to ouuan for his work in making snippets available.

View Modes: CP Editor now has 3 view modes, in Editor mode the complete window of the application will be occupied with Code Editor, in IO Mode complete window will be occupied by Input output boxes and normal mode is called Split Mode, in which window is shared between the two. You can even set hotkeys to toggle the views from Preferences for a quick change of view modes.
You now have ability to just apply settings. There are three options, "Okay", "Apply" and "Cancel", Okay will close the window and settings will be applied and Apply will keep the preference window open while settings are applied and Cancel will close the preference window.
There are many other bug fixes and quality of experience improvements. There are some performance improvements too.

Star the project and spread the word about this editor.
else you can open Editor and Help -> Support me, to buy me a coffee

I will be busy with my new semester and also with Google Summer of Code 2020, Hence pace of development will slow down a bit for this project starting today.

If you found any bugs or have any feature requests, please open an issue here, and don't forget to follow the issue templates. Users' responses are important for contributors to improve the project.

If you want a try on developing, you can install Qt and CMake, then fix bugs / make new features by yourself! After finishing the coding, just open a pull request here. Don't worry if you are not familiar with Qt / GUI programming, Google is your friend, and Qt is a well documented library. I've never used Qt before contributing to CP Editor, but I've made 33 commits, including 1979 additions and 1620 deletions up to now.

One of those times where the like button for a comment is not enough.

I will always welcome contributions to the work. Together we can build an editor for ourselves.

Your extension will have it’s own codeforces soon :D

There have been many new features since 5.0:

New Test Cases UI. Now you can open up to 100 test cases or delete some of them. It's also easier to add tests from files.
New Diff Viewer. The new diff viewer uses diff-match-patch, so that you can see the beautiful diff result in HTML.
New File Logic. Now the tab status/open files/save files are almost the same as Sublime. For example, external file changes on the disk is detected.
Hot Exit. Now you can save the status for the next session.
Transparency Setting. You can set the transparency for the editor. Then, you can see the problem statement/your desktop/some pictures while coding, or just be cool.
Single Application. Now when you open a new file while there is a CP Editor running, the new file will be opened in a new tab instead of a new window.
Open Contests. You can open a folder with A.cpp, B.cpp, ..., Z.cpp easily. The folder and the number of files (number of problems) is chosen by you.
Command-Line Options. See CPEditor --help for more information. Now it's easier to open CP Editor from the command line.
Open File Progress Bar. Show progress bar for file opening.
Tab Bar Context Menu. A menu with options like Close Others/Reveal in Explorer. Right-click on the tab bar to open it.
Many bug fixes.

Some features are not well-tested yet, if you are interested in them, try it and report bugs if you find any.

Again, contributions are always welcomed, together we can build a better editor for ourselves.

When we open contest and create 'n' files,and after that when we parse tasks from contest do the test cases(of the corresponding problem) get updated or new tabs come up?

I checked it now,its not updating rather creating new tabs. It would be better if just the test cases would have got updated so that we can directly save our code and submit.

You can use Competitve Companion to parse a contest.

Yes,but what I meant to say is when we parse contest,it would be better to just update the test cases of the created contest in cp-editor than creating more new tabs.

The basic idea of this feature is that you can save directly without choosing where to save.

If you want new features, open issues on Github.

UPD: I didn't read his comment carefully so I didn't realize he is talking about parsing a contest after "Open Contest".

When I press ctrl+shift+U on contest dashboard, I got [an invalid Payload was delivered on the listening port] in CP-editor, How can I resolve this?

What does this shortcut does. Press Green plus icon on contest dashboard.

Got same error even on pressing green icon.

Which version of editor? See Help->About

← Rev. 2 →

5.8.3

Please try with latest stable 5.7.1-stable, if you still have that issue take a minute and open issue on GitHub. https://github.com/coder3101/cp-editor

Also please let me know the competitive companion version and the browser you are using.

Also try parsing some other problem or contest.

I raises an issue and also attached image there, please look over that once

still facing same problem in version 5.7.1 stable

5.8.3 is beta and not tested release.

But the competitive companion part is nearly the same.

Did the same as mentioned in above procedure but getting the error as -

[You will not be able to submit code to Codeforces because CFTools is not installed or is not on SYSTEM PATH. You can set it manually in settings.]

Can anyone help me with the solution for this problem!!

Thanking You in advance.

You can set the path of CF Tool in the preferences (Options→Preferences→Extras→Misc→CF Tool Command), just like the "error" said.
