# darkcloud-nvimconfig

A theme, config and collection of plugins for Neovim

## Requirements

* **Neovim**: [neovim](https://neovim.io) is a hard dependency
* **Bash**: Required by the _update_ script
* **Coreutils**: Required by the _update_ script
* **Git**: Required by the _update_ script and git-related plugins

## Optional Requirements

* **Powerline Fonts**: Required to enable the fancier looking status line
* **Universal CTags**: Required by _vim-gutentags_ and _vista_, and optional for _nvim-cmp_
* **Compilers, Linters and Runtimes**: The _ale_ plugin can use compilers, linters and runtimes to provide real-time syntax checking

## Distribution Features

* **Default Configuration**: A complete set of defaults, focusing on the most modern settings that still provide a compatible experience
* **Custom theme**: An original colour scheme with explicit values set to optimize the look of individual filetypes
* **Key Bindings/Aliases**: A set of bindings and aliases defined to group similar features and provide numerous (and sometimes more familiar) ways to access options
* **Plugins**: A set of plugins have been included and configured to provide support for most normally-unsupported filetypes, and a set of features useful when using Vim as an editor
* **Custom Configuration**: A second vimrc and bundle folder are included that aren't maintained as part of the repo, making custom plugins and configuration easy to add

## Installation

1. Clone the darkcloud-nvimconfig repo and run the `update` script
2. By default darkcloud-nvimconfig expects to be installed @ `/etc/darkcloud-nvimconfig`, if you're installing it elsewhere you should add `let g:darkcloudpath = "/path/to/darkcloud-nvimconfig"` to your neovim init
3. Add `source /path/to/darkcloud-nvimconfig/init.vim` to your neovim init (after `let g:darkcloudpath = ...` if present)

## Configuration

* **Configure Variables**: The following variables can be added to `local/user.vim` and have their values set to the values you require:
  * `g:autostartchecker`: **1** = Enable the syntax checker when a file is opened | **0** = Check syntax only after being toggled on (default: **0**)
  * `g:enabletreesitter`: **1** = Use treesitter for compatible files | **0** = Keep treesitter disabled (default: **0**)
  * `g:enablecompletion`: **1** = Enable autocompletion | **0** = Disable autocompletion (default: **0**)
  * `g:enableautotags`: **1** = Automatically generate tags files | **0** = Disable tag generation (default: **0**)
  * `g:enablepowerline`: **1** = Render the statusline using characters that require powerline-patched fonts | **0** = Render the statusbar with characters that work with all fonts (default: **0**)
* **Custom Plugins**: Pathogen compatible plugins can be cloned or extracted to `local/bundle/`, or a folder named `bundle` in any of the folders in the runtimepath
* **Update Script**: (requires: bash+git) Use the `update` script to update the project and submodules, as well as handle any required maintenance
