About

Wgurecky's neovim configuration files. Useful for rust, cpp, python, and latex files.

This config depends on neovim's new lsp (language server protocol) integration.

Work in progress:

• Migrating to pure lua configuration.

Depends

• neovim with built in lsp (neovim >=v0.5) formerly nvim-lsp
• rust-analyzer
• ty
• ruff
• pynvim
• clang
• clangd

Neovim plugins are not listed here. lazy.nvim handles installation and updates of all neovim plugins.

Optional

• ripgrep
• clang-tidy

Install

Clone this repo into your ~/.config dir:

cd ~/.config && git clone https://github.com/wgurecky/nvim

On neovim startup lazy.nvim should try to download automatically, if not install from https://github.com/folke/lazy.nvim

Next, run :Lazy sync to install all plugins followed by :Lazy show

Config

C++ / C

This neovim configuration assumes that a C/C++ project is built out of the src tree and is a git repository:

PROJECT_BASE
+-- CMakeLists.txt
+-- README.md
+-- .git
|   +-- FETCH_HEAD
|   +-- '...'
+-- build
|   +-- do_configure.sh
|   +-- makefile
+-- src
|   +-- foo_bar.cpp
|   +-- foo_bar.hpp

Build

A function present in the included init.vim attempts to set makeprg automatically. The function might not always produce the expected result. Check that makeprg is set by issuing:

:set makeprg

To manually set makeprg:

:set makeprg=make\ -C\ ~/path/to/project/build

Once makeprg is verified, run:

:Make!

Which will launch make in the background so that you can continue to edit uninterrupted. To view the results run:

:Copen

Note: The designated project build folder name can be adjusted in the ./ftplugin/<c,cpp> files. By default it is set to build.

Auto Completion

Clangd provides autocompletion for C/C++ projects. Some linux distributions have a clang-tools package that contains Clangd.

To use Clangd you must first generate a compilation database with the cmake option:

cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=on \

If cmake is not the build system of choice one can use the tool Bear to generate a json compilation database instead.

Python

Optional: Place flake8 file in ~/.config/. to ignore some minor PEP8 violation warnings from showing up in the quickfix window.

Auto Completion

Auto complete for python requires the ty language server to be installed:

pip install ty

Linting

Install ruff, for ex:

pip install ruff

Breakpoints in Python

In normal mode <leader> b inserts a breakpoint on the line above the current cursor position.

Notes

Telescope Find File

To search for a file in the current project:

<C-p>

Find/Replace Mappings and Shortcuts

To search and replace a word inside all files in a directory:

:Ack {pattern} [{dir}]
:cdo s/foo/bar/gc | update

To search and replace all instances of a word inside a project that is a git repository use:

:vg <pattern>
:cdo s/foo/bar/gc | update

or

<C-f> <pattern>
<C-q>
:cdo s/foo/bar/gc | update

To search and replace all instances of the current word under the cursor in the current git repo do:

<leader>*
<C-q>
:cdo s/foo/bar/gc | update

Where <leader> is set to \ by default. The <C-q> (Ctrl+q) is required to send the telescope results to the quickfix list.

To find replace the current word under the cursor in the current file use:

<leader>s

Code folding

The ./ftplugin directory provides code folding settings. By default, folding by indentation level is on. za toggles folding for the current indent level. zR and zM unfolds and folds all respectively.
