" SpaceVim is a bundle of custom settings and plugins with a modular
" configuration for Vim. It was inspired by Spacemacs.
"

""
" @section Options, options
" SpaceVim uses `~/.SpaceVim.d/init.toml` as its default global config file.
" You can set all the SpaceVim options and layers in it. `~/.SpaceVim.d/` will
" also be added to runtimepath, so you can write your own scripts in it.
" SpaceVim also supports local config for each project. Place local config
" settings in `.SpaceVim.d/init.toml` in the root directory of your project.
" `.SpaceVim.d/` will also be added to runtimepath.
"
" here is an example setting SpaceVim options:
" >
"   [options]
"     enable-guicolors = true
"     max-column = 120
" <

" @section Configuration, config
" If you still want to use `~/.SpaceVim.d/init.vim` as configuration file,
" please take a look at the following options add @section(functions)


""
" @section Public functions, functions
" All of these functions can be used in `~/.SpaceVim.d/init.vim` and bootstrap
" functions.

" @section search-and-replace, usage-search-and-replace
" @parentsection usage
" This section document how to find and replace text in SpaceVim.
"
" @subsection Searching with  an external tool
"
" SpaceVim can be interfaced with different searching tools like:
" 1. rg - ripgrep
" 2. ag - the silver searcher
" 3. pt - the platinum searcher
" 4. ack
" 5. grep
" The search commands in SpaceVim are organized under the `SPC s` prefix
" with the next key being the tool to use and the last key is the scope.
" For instance, `SPC s a b` will search in all opened buffers using `ag`.
" 
" If the `<scope>` is uppercase then the current word under the cursor
" is used as default input for the search.
" For instance, `SPC s a B` will search for the word under the cursor.
" 
" If the tool key is omitted then a default tool will be automatically
" selected for the search. This tool corresponds to the first tool found
" on the system from the list `search_tools`, the default order is
" `['rg', 'ag', 'pt', 'ack', 'grep', 'findstr', 'git']`.
" For instance `SPC s b` will search in the opened buffers using
" `pt` if `rg` and `ag` have not been found on the system.
" 
" The tool keys are:
" >
"     Tool     | Key
"     ---------|-----
"     ag       | a
"     grep     | g
"     git grep | G
"     ack      | k
"     rg       | r
"     pt       | t
" <
" The available scopes and corresponding keys are:
" >
"     Scope                      | Key
"     ---------------------------|-----
"     opened buffers             | b
"     buffer directory           | d
"     files in a given directory | f
"     current project            | p
" <
" Instead of using flygrep to search text. SpaceVim also provides a general
" async searcher. The key binding is `SPC s j`, an input promote will be
" opened. After inserting text and press enter. searching results will be
" displayed in quickfix window.

""
" @section FAQ, faq
" This is a list of the frequently asked questions about SpaceVim.
"
" 1. How do I enable YouCompleteMe?
"
"   Step 1: Add `enable_ycm = true` to custom_config. By default it should be
"   `~/.SpaceVim.d/init.toml`.
"
"   Step 2: Get into the directory of YouCompleteMe's author. By default it
"   should be `~/.cache/vimfiles/repos/github.com/Valloric/`. If you find the
"   directory `YouCompleteMe` in it, go into it. Otherwise clone
"   YouCompleteMe repo by
"   `git clone https://github.com/Valloric/YouCompleteMe.git`. After cloning,
"   get into it and run `git submodule update --init --recursive`.
"
"   Step 3: Compile YouCompleteMe with the features you want. If you just want
"   C family support, run `./install.py --clang-completer`.
" 
"
" 2. How to add custom snippet?
" 
"  SpaceVim uses neosnippet as the default snippet engine. This can be changed
" by @section(options-snippet_engine) option.
"
"  If you want to add a snippet for a current filetype, run |:NeoSnippetEdit|
" command. A buffer will be opened and you can add your custom snippet.
" By default this buffer will be save in `~/.SpaceVim.d/snippets`.
"
"  For more info about how to write snippet, please
" read |neosnippet-snippet-syntax|.
"
"
" 3. Where is `<c-f>` in cmdline-mode?
" 
"   `<c-f>` is the default value of |cedit| option, but in SpaceVim we use that
" binding as `<Right>`, so maybe you can change the `cedit` option or use
"   `<leader>+<c-f>`.
"
" 4. How to use `<Space>` as `<Leader>`?
" 
"   Add `let g:mapleader = "\<Space>"` to bootstrap function.
" 
" 5. Why does Vim freeze after pressing Ctrl-s?
"
"   This is a feature of terminal emulators. You can use `Ctrl-q` to unfreeze Vim. To disable
" this feature you need the following in either `~/.bash_profile` or `~/.bashrc`:
">
"   stty -ixon
"<
"
" 6. How to enable `+py` and `+py3` in Neovim?
"
"   In Neovim we can use `g:python_host_prog` and `g:python3_host_prog`
"   to config python prog. But in SpaceVim the custom configuration file is
"   loaded after SpaceVim core code. So in SpaceVim itself, if we using `:py`
"   command, it may cause errors.
"   
"   So we introduce two new environment variables: `PYTHON_HOST_PROG` and
"   `PYTHON3_HOST_PROG`.
"
"   For example:
" >
"   export PYTHON_HOST_PROG='/home/q/envs/neovim2/bin/python'
"   export PYTHON3_HOST_PROG='/home/q/envs/neovim3/bin/python'
