# 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_ and _gentags_ scripts
* **Coreutils**: Required by the _update_ script
* **Git**: Required by the _update_ script and git-related plugins

## Optional Requirements

* **Compilers, Linters and Runtimes**: The ale plugin can use compilers, linters and runtimes to provide real-time syntax checking
* **CTags**: Required by the _tagbar_ and _deoplete_ plugins as well as the _gentags_ script ([ctags website](http://ctags.sourceforge.net))
* **Powerline Fonts**: Required to enable the fancier looking status line ([powerline-fonts repo](https://github.com/Lokaltog/powerline-fonts))
* **Python**: Required for _deoplete_ autocompletion functionality
* **Neovim Python Module**: Required for _deoplete_ autocompletion
* **Python Msgpack**: Required for _deoplete_ autocompletion

## 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 the config expects darkcloud-nvimconfig 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 the neovim init that you want to use the config with

## 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:autostarttagbar`: **1** = Load a file with the tagbar visible | **0** = Require the tagbar to be 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 Settings**: Settings with priority over those set by darkcloud-nvimconfig can be added to `local/user.vim`
* **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
