# darkcloud-nvimconfig
2024-03-01 16:28:35 -05:00
A theme, config and collection of plugins for Neovim
## Requirements
* **Vim**: The latest [vim](http://www.vim.org) should be installed to use this distribution.
* **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.
2018-03-13 15:38:03 -04:00
* **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 and _MatchTagAlways_ 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
2024-03-01 16:28:35 -05:00
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
### Vimpager
2024-03-01 16:28:35 -05:00
You can configure your PAGER to use darkcloud-nvimconfig using vimpager by adding the following to your bashrc (assuming the default path @ _"/etc/darkcloud-nvimconfig"_):
```
2024-03-01 16:28:35 -05:00
export PAGER=/etc/darkcloud-nvimconfig/vim/bundle/vimpager/vimpager
alias less="$PAGER"
alias zless="$PAGER"
```
## Configuration
2024-03-01 16:28:35 -05:00
* **Configure Variables**: The following variables can be added to `vim/user.vim` and have their values set to the values you require:
* `g:autostartchecker`: **1** = Check syntax once an appropriate file is loaded | **0** = Check syntax only after syntax checking is toggled on (_default_: **0**)
* `g:autostarttagbar`: **1** = Have the tagbar load automatically when a compatible format is run | **0** = The tagbar will stay hidden until triggered on demand with its toggle (_default_: **0**)
2018-03-13 15:38:03 -04:00
* `g:disablecompletion`: **1** = Disable _deoplete_ autocompletion | **0** = Enable _deoplete _autocompletion_ if the requirements are met (_default_: **0**)
* `g:disableautotags`: **1** = Prevent tags from being automatically generated and highlighted | **0** = Automatically generate and highlight tags (_default_: **0**)
* `g:disablelinebreaks`: **1** = Override filetype plugins so linebreaks never occur | **0** = Linebreaks are disabled by default, but filetype plugins can override this setting (_default_: **0**)
* `g:powerlinefonts`: **1** = Render the statusline using characters available with powerline-patched fonts | **0** = Render the statusbar with less attractive but more compatible characters available in all fonts (_default_: **0**)
2024-03-01 16:28:35 -05:00
* **Custom Settings**: Settings with priority over those set by darkcloud-nvimconfig can be added to `vim/user.vim` or any of the folders in the runtimepath.
* **Custom Plugins**: Pathogen compatible plugins can be cloned or extracted to `darkcloud-nvimconfig/vim/bundle.user/`, 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, generate docs from the pathogen plugins and create missing config scripts with preset values.
