Setting up Coc Vim

To unleash your coding skills with Coc Vim, you'll need to set it up properly. Here's a step-by-step guide:

  1. Make sure you have Vim installed on your system.
  2. Install Node.js on your system to be able to use Coc Vim.
  3. Install the Coc Vim plugin for Vim using your plugin manager of choice (e.g. vim-plug or Vundle).
  4. Install the language servers for the programming languages you want to work with. This allows Coc Vim to provide accurate and efficient autocompletion suggestions based on the language-specific context. For example, to set up the C language server, you can run the following command: :CocInstall coc-ccls.
  5. Configure the Coc Vim settings to your preferences, such as enabling/disabling certain features or key bindings.
  6. Enjoy using the ultimate C autocompletion tool!

With Coc Vim set up properly, you'll have access to advanced code autocompletion, syntax highlighting, and smart refactoring tools that can greatly enhance your coding experience.

Basic Coc Vim commands

Using Coc Vim can seem intimidating, but once you get the hang of it, you can unlock its full potential. Here are some basic commands to get you started:

  • :CocInstall [extension]: This command installs a Coc Vim extension, which adds new features and autocompletion for different languages.

  • :CocList extensions: This command displays a list of all installed Coc Vim extensions, including their features and version numbers.

  • :CocConfig: This command opens the configuration file for Coc Vim, where you can customize settings for different features, such as autocompletion threshold and formatting options.

  • <Leader> g d: This command jumps to the definition of a function or variable. You can define your own leader key by adding let mapleader = "," to your .vimrc file, for example.

  • <Leader> r: This command renames a variable, function or file, and updates all references automatically. This is a powerful feature that can save you a lot of manual labor.

  • <Leader> f: This command searches for files or symbols in the project, and displays a list of results that you can navigate easily. You can filter by filename, type, and other options.

  • <Leader> a: This command triggers autocompletion suggestions for the current cursor position, based on the language and libraries you're using.

By using these simple commands, you can start to explore the wealth of features that Coc Vim offers for coding and debugging. Over time, you may find yourself tweaking your settings and adding new extensions to make your workflow even smoother.

Live examples of C autocompletion using Coc Vim

Coc Vim is an ultimate autocompletion tool for C programmers that provides live examples to streamline the coding process. Let's take a closer look at some :

  • Structs and Pointers: Coc Vim can complete structures, their members, and pointer access without any explicit configuration. It uses clangd for parsing, and that's how it provides accurate completion. By typing struct [variable], you can see a list of members that you can access. Moreover, you can see a description of each member so that you know what to expect.

  • Suggestions for Required Headers: Coc Vim automatically suggests the headers that are usually required for a particular function or keyword. For example, when you type malloc, Coc Vim suggests the header file <stdlib.h> that needs to be added to your program to use this function. This feature saves a lot of time and effort searching for the appropriate header files, especially when dealing with complex programs.

  • Type Inference: In C language, you have to specify the type of a variable before using it. However, Coc Vim makes this process easier by inferring types based on context. When you type list = malloc(sizeof(, Coc Vim will suggest the data type based on the value in the parentheses. This saves time and reduces the chance of errors.

  • Code Navigation: Coc Vim also provides powerful code navigation features for C programmers. For instance, by pressing gd in normal mode, you can jump to the definition of a function, structure, or variable under the cursor. This is useful when debugging or modifying code.

Coc Vim is an excellent tool for C programmers who want to increase their productivity and improve their coding experience. With its powerful autocompletion, code navigation, and type inference features, it simplifies the development process and enables programmers to focus on writing code rather than searching for syntax errors or missing headers. Try it out and see for yourself how much time and effort it can save you!

Tips and tricks for efficient coding with Coc Vim

Coc Vim, the ultimate C autocompletion tool, is a powerful tool that can help streamline your coding workflow. Here are some tips and tricks to help you get the most out of this tool:

  • Use the language server protocols: Coc Vim uses language server protocols to provide autocompletion, code navigation, and other features. By default, it supports several popular languages like JavaScript, TypeScript, Rust, and PHP. However, if you're working with a custom language, you can create your own language server using the LSP specification.

  • Configure your settings: Coc Vim comes with many configuration options that allow you to customize its behavior. For example, you can set the amount of buffer space that is allowed for the autocompletion menu, or choose to display completions in a split window. You can also configure the formatting options and define your own mappings for the tool.

  • Use the snippet support: Coc Vim supports snippet expansion, which allows you to define custom code templates that can be quickly inserted into your code. This is particularly useful for frequently used code patterns or boilerplate code. You can define your own snippets or use pre-defined snippets provided by Coc Vim.

  • Take advantage of Vim plugins: Coc Vim is designed to work seamlessly with Vim, and you can use Vim plugins to extend its functionality even further. For example, you can use the 'vim-commentary' plugin to quickly comment and uncomment blocks of code, or 'fzf' plugin to easily search for and open files.

By using these tips and tricks, you can unleash the full power of Coc Vim and take your coding skills to the next level. Whether you're a beginner or an experienced programmer, this tool can help you write better code and be more productive.


In , Coc Vim is an excellent tool for anyone looking to improve their C coding skills.
