vim-rust-ide

My attempt to make vim more rust friendly from an IDE perspective

These instructions get neovim setup for

• Autocompletion
• Live-linting
• Autoformatting
• Syntax-highlighting
• hover docs
• jump to def

Install the rust toolchains

Install rustup Add ~/.cargo/bin to PATH echo "~/.cargo/bin" >> ~/.bashrc

RLS

Rust Language Server RLS

rustup toolchain install stable
rustup toolchain install nightly
rustup default stable
rustup component add rls rust-analysis rust-src

Racer

Rust Code Completion utility Racer

cargo +nightly install racer

It is recommeded to set RUST_SRC_PATH for speed it isn't needed

echo "export RUST_SRC_PATH=\"$(rustc --print sysroot)/lib/rustlib/src/rust/src\"" >> ~/.bashrc

rustfmt

Format Rust code rustfmt

cargo install rustfmt-nightly

python modules

Most operating systems come with python installed Python

Need to have msgpack >= 1.0.0

python3 -m pip install -U pynvim msgpack

nodejs install

coc.nvim uses nodejs. Some may not like nodejs installed. If that is the case use deoplete. There are some commits in the repo that have examples of how to use it with rust. coc.nvim

curl -sL install-node.now.sh/lts | bash

Neovim

vim-plug

curl -fLo ~/.local/share/nvim/site/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

Install neovim Neovim

Update ~/.config/nvim/init.vim using init.vim file in source repo

cp init.vim ~/.config/nvim/

Install patched powerline font (Optional)

SauceCodePro

Start neovim

nvim

Inside neovim install plugins :PlugInstall Inside neovim install Coc :CocInstall

Alacritty terminal (Optional)

cp alacritty.yml ~/.config/alacritty/

Tmux (Optional)

Install tmux Tmux

Copy tmux.conf from repo

cp tmux.conf ~/.tmux.conf

tmux

ctrl+b I to install plugins ctrl+b r to reload tmux

Prettier Formatter (downside is it relies on editorconfig and not rustfmt.toml)

prettier cd ~/.config/coc/extensions

npm install coc-prettier

Open nvim :CocConfig

Update the file

{
  "coc.preferences.formatOnSaveFiletypes": ["*"]
}
