There is no doubt, coding is getting more complex nowadays. I have to code in Python, C and C++ and I have usually used vi for small edits. For production I have used PyCharm, for C, C++ Visual Studio.
Visual Studio Code is a great editor with multiple extensions to support different languages. Although, I am used to vim and I always tried to setup intellisense to support different languages.
I like to use Visual Studio Code, however, I feel more productive with vi editor. In this post I’m setting up NeoVim with Coc to code in my favorite languages. In the past I tried vim with different plugins to have code completion.
Finally, I think NeoVim plus Coc is a good option to use vim.
COC requires nodejs and yarn. So, first step is to install those tools:
Install nodejs, create node repo:
curl -sL https://rpm.nodesource.com/setup_14.x | sudo bash
Install nodejs
sudo dnf install nodejs
Install yarn:
Create yarn repo with
[yarn]
name=Yarn Repository
baseurl=https://dl.yarnpkg.com/rpm/
enabled=1
gpgcheck=1
gpgkey=https://dl.yarnpkg.com/rpm/pubkey.gpg
Install yarn
sudo dnf install yarn
Install Vim Plug:
sh -c 'curl -fLo "${XDG_DATA_HOME:-$HOME/.local/share}"/nvim/site/autoload/plug.vim --create-dirs \
https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'
Setup Plugin Manager in your init.vim file:
Plug 'neoclide/coc.nvim', {'do': 'yarn install --frozen-lockfile'}
Launch NeoVim and manage code completion from inside NeoVim. This is what I like more about COC, you can install all the code completion extensions using CocInstall:
CocInstall coc-rust-analyzer and others....
PYTHON
Notes: Set interpreter to python 3. Optional use Jedi or language server. I’ll use Jedi:
I had to remove python3-jedi package from Fedora and install it with pip3. You can use CocConfig to setup json file and toggle jedi or language server.
C++
RUST
You need to setup Rust-Analyzer with CocConfig
GO
SetUp Go settings with CocConfig.
My coc-settings.json:
