Installation ⚡

The following instructions are for Windows (powershell). An admin prompt is required.

1. Install chocolatey.

   Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

2. Install main dependencies.

   choco install -y git.install --params "/GitAndUnixToolsOnPath /NoGitLfs /SChannel /NoShellIntegration";
   choco install -y neovim python SumatraPDF.install miktex.install;
   # Needed for various plugins
   choco install -y universal-ctags strawberryperl make SQLite ripgrep fd golang; refreshenv; exit
   

3. Install python dependencies.

   pip install pynvim neovim-remote
   

4. Clone the repository and open nvim-qt or nvim.

   For fresh installation:

   git clone https://github.com/Neelfrost/nvim-config.git "$HOME\Appdata\Local\nvim"; nvim-qt.exe
   

   For existing config:

   ren "$HOME\Appdata\Local\nvim" 'nvim-old'; git clone https://github.com/Neelfrost/nvim-config.git "$HOME\Appdata\Local\nvim"; nvim-qt.exe
   

LaTeX

Formatting (latexindent)

latexindent is now included with miktex, so downloading it separately is no longer necessary. Moreover, null-ls is pre-configured to run latexindent on save for tex files. Global formatting rules can be changed by:

1. Creating $HOME/indentconfig.yaml:

   paths:
     - C:\Users\<username>\defaultSettings.yaml

2. Creating $HOME/defaultSettings.yaml, followed by copying and overriding defaultSettings.

For further reading refer: docs.

Viewing PDF

To launch SumatraPDF using VimTeX (\lv), ensure SumatraPDF.exe is added to environment path.

Inverse Search

For inverse search, open SumatraPDF then go to Settings -> Options and set inverse search command-line to:

cmd /c start /min nvim --headless -c "PackerLoad vimtex" -c "VimtexInverseSearch %l '%f'"
