A Posh Sublime Setup in Ubuntu

Here is a posh Sublime setup for Ubuntu that includes the following features:

1. Build system with timeout and memory limit
2. Build system to run program in the terminal
3. Problem parser
4. Linter
5. Good suggestions similar to VS Code.

Sublime Installation

First, we need to install Sublime. You can download it from the Ubuntu Software Center.

Alternatively, you can use the following commands to install Sublime:

wget -qO - https://download.sublimetext.com/sublimehq-pub.gpg | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/sublimehq-archive.gpg > /dev/null
echo "deb https://download.sublimetext.com/ apt/stable/" | sudo tee /etc/apt/sources.list.d/sublime-text.list

sudo apt update
sudo apt install sublime-text

gcc Installation

If you don't have the C++ compiler installed, then open the terminal and type the following command to install it.

sudo apt install gcc g++

Procedures

1. Making build system with time and memory limit

• Open Sublime and create a view for three files. Go to View -> Layout -> Columns: 2. Then, with the cursor in the right column, go to View -> Groups -> New Group

• Now open your c++ file and create 2 files named input.txt and output.txt in the same directory as you c++ file. Your code will take input from the input.txt file and write output to output.txt.

• Now create a new build system by selecting Tools -> Build Systems -> New Build System. Copy the contents of the file CppIO.sublime-build and paste it into the build system you created and save it.

  Note : Make sure you are saving the build system in the sublime's package file. Make sure the name of the build system ends with .sublime-build, for example CppIO.sublime-build.

• Now select the automatic build system by going Tools -> Build System -> Automatic. Press ctrl + shift + b. And select the build system you created(for example: CppIO ). Now press ctrl + b and the code will run.

2. Setting up Terminus for terminal based build system

• Install Terminus package for accessing terminal in sublime. Press ctrl + shift + p and type "install" and choose "install package", then type Terminus and chose terminus and press enter.

• Create a build system to run programs in terminal. Copy the contents of the file Cpp Terminal.sublime-build. Now go to Tools -> Build Systems -> New Build System and paste and save the build system.

  Note : Make sure you are saving the build system in the sublime's package file. Make sure the name of the build system ends with .sublime-build, for example Cpp Terminal.sublime-build.

• To run the terminal build system press ctrl + shift + b and select the terminal build system(for example: Cpp Terminal).

3. Setting up problem parser

• Now its time to setup the problem parser. Press ctrl + shift + p and type install and choose "install package" and wait. Once the packages loaded type "cppfastolympiccoding" and chose CppFastOlympicCoding and wait for it to install. Once its instelled press ctrl + alt + b and it will pop up an window at the right runing the current code.

  Note : If install package option is not available, there might be an option called Install package control, select that, and after some time you would get the message "installed package control" after that you can install package.

• Now go to Preferences -> Browse Package . Open a terminal on that folder and run this command. This is a repo of DrSwad

  git clone https://github.com/DrSwad/FastOlympicCodingHook.git
  

  Note : if you don't have git, install it using this command

  sudo apt install git
  

• Now open up your browser and install an extension called Competitive Companion.
  a. If you are using chrome when you go to the options of the extension, a popup box will occur before you asking for the port. Type 12345 and close the popup box.
  b. If you are using firefox, then go the the settings of the extension. Then in the preferences menu set the port to 12345

• Now when you right click on a file in subilme you will see an option called Listen to competitive companion. Now we'll change the run key bindings and make some optimization. First go to Preferences -> Browse Package -> CppFastOlympicCoding then open Default (Linux).sublime-keymap. Using ctrl + f find ctrl + alt + b and change it to ctrl + ;. Threre will be 2 occurences. Change both of them.

• Copy all the content in the Default (Linux).sublime-keymap and go to Preferences -> Key bindings. In the right panel paste everything you copied.

• Press ctrl + shift + p and type setting and go to cppfastopympiccoding setting. In the left panel, in "run_settings", in compile_cmd change the -std=c++11 to -std=c++17, and in the lint_compile_cmd change the -std=gnu++11 to -std=gnu++17. And you are set to go.

• The procedure to get problem test case is -
  a. Press Ctrl + h
  b. Then go the problem page and click on the competitive companion icon.
  c. When the blue line goes from left to right, then the test cases will be fetched from the page to sublime. Now go to sublime and press ctrl + ;.

4. Setting up Linter

• Problem parser is done, now lets setup the linter and auto suggestion. We need to install 2 packages, SublimeLinter, SublimeLinter-gcc for linter. Press ctrl + shift + p and type "install" and choose install package and install these packages one by one.

• Copy all the content from SublimeLinter.sublime-settings. Now press ctrl + shift + p and type "Settings" and choose "SublimeLinter - Settings" and in the right panel paste everything you copied.

5. Setting up auto suggestion

• For auto suggestion install package called LSP. Press ctrl + shift + p and type "install" and choose "install package" and install the package.

• Now open terminal and install clangd

  sudo apt install clangd
  

• Now go to sublime and type ctrl + shift + p and type setting and go to "LSP - Settings". Now copy all the content from LSP.sublime-settings and paste in the LSP setings file.

• Now the auto suggestion and linter both will work.
