+" 
+" If `has('unnamedplus')`, the register used by `<Leader> y` is `+`,

+" >
+"   curl -s -F "content=<-" http://dpaste.com/api/v2/

+"    SPC c $     | comment current line from cursor to the end of the line
+" <
+" Tip: `SPC ;` will start operator mode, in this mode, you can use a motion 
+" command to comment lines. For example, `SPC ; 4 j` will comment the current
+" line and the following 4 lines.
+" 
+" @subsection Undo tree
+" 
+" Undo tree visualizes the undo history and makes it easier to browse
+" and switch between different undo branches. The default key binding is `F7`.

+" @subsection Multi-Encodings
+" 
+" SpaceVim uses utf-8 as the default encoding. There are four options for this:
+" 
+" 1. fileencodings (fencs): ucs-bom,utf-8,default,latin1
+" 2. fileencoding (fenc): utf-8
+" 3. encoding (enc): utf-8
+" 4. termencoding (tenc): utf-8 (only supported in Vim)
+" 
+" To fix a messy display: `SPC e a` is the mapping to auto detect the file
+" encoding. After detecting the file encoding, you can run the command below
+" to fix it:
+" >
+"   set enc=utf-8

+TEXT INSERTION COMMANDS
+
+Text insertion commands (start with `i`):
+>
+  Key bindings | Descriptions
+  ------------ |
+    ---------------------------------------------------------------------
+   SPC i l l   | insert lorem-ipsum list
+   SPC i l p   | insert lorem-ipsum paragraph
+   SPC i l s   | insert lorem-ipsum sentence
+   SPC i p 1   | insert simple password
+   SPC i p 2   | insert stronger password
+   SPC i p 3   | insert password for paranoids
+   SPC i p p   | insert a phonetically easy password
+   SPC i p n   | insert a numerical password
+   SPC i u     | Search for Unicode characters and insert them into the active
+    buffer.
+   SPC i U 1   | insert UUIDv1 (use universal argument to insert with CID
+    format)
+   SPC i U 4   | insert UUIDv4 (use universal argument to insert with CID
+    format)
+   SPC i U U   | insert UUIDv4 (use universal argument to insert with CID
+    format)
+<
+
+>
+<
+NOTE: You can specify the number of password characters using a prefix
+argument (i.e. `10 SPC i p 1` will generate a 10 character simple password).
+
+EXPAND REGIONS OF TEXT
+
+Key bindings available in visual mode:
+>
+  Key bindings | Descriptions
+  ------------ | -------------------------------------------------
+   v           | expand visual selection of text to larger region
+   V           | shrink visual selection of text to smaller region
+<
+INCREASE/DECREASE NUMBERS
+
+>
+  Key Bindings | Descriptions
+  ------------ | ------------------------------------------------
+   SPC n +     | increase the number and initiate transient state
+   SPC n -     | decrease the number and initiate transient state
+<
+In transient state:
+>
+  Key Bindings  | Descriptions
+  ------------- | -------------------------------------------
+   +            | increase the number under the cursor by one
+   -            | decrease the number under the cursor by one
+  Any other key | leave the transient state
+<
+Tip: You can set the step (1 by default) by using a prefix argument (i.e. `10
+SPC n +` will add 10 to the number under the cursor).
+
+COPY AND PASTE
+
+If `has('unnamedplus')`, the register used by `<Leader> y` is `+`, otherwise
+it is `*`. Read `:h registers` for more info about other registers.
+>
+  Key          | Descriptions
+  ------------ | --------------------------------------------
+   <Leader> y  | Copy selected text to system clipboard
+   <Leader> p  | Paste text from system clipboard after here
+   <Leader> P  | Paste text from system clipboard before here
+   <Leader> Y  | Copy selected text to pastebin
+<
+To change the command of clipboard, you need to use bootstrap after function:
+>
+  " for example, to use tmux clipboard:
+  function! myspacevim#after() abort
+    call clipboard#set('tmux load-buffer -', 'tmux save-buffer -')
+  endfunction
+<
+
+within the runtime log (`SPC h L`), the clipboard command will be displayed:
+
+
+>
+  [ clipboard ] [11:00:35] [670.246] [ Info  ] yank_cmd is:'tmux load-buffer
+    -'
+  [ clipboard ] [11:00:35] [670.246] [ Info  ] paste_cmd is:'tmux save-buffer
+    -'
+<
+
+>
+
+<
+The `<Leader> Y` key binding will copy selected text to a pastebin server. It
+requires `curl` in your `$PATH`. The default command is:
+>
+  curl -s -F "content=<-" http://dpaste.com/api/v2/
+<
+This command will read stdin and copy it to dpaste server. It is same as:
+>
+  echo "selected text" | curl -s -F "content=<-" http://dpaste.com/api/v2/
+<
+
+COMMENTING
+
+Comments are handled by nerdcommenter, it’s bound to the following keys.
+>
+  Key Bindings | Descriptions
+  ------------ | -------------------------------------------------------
+   SPC ;       | comment operator
+   SPC c a     | switch to the alternative set of delimiters
+   SPC c h     | hide/show comments
+   SPC c l     | toggle line comments
+   SPC c L     | comment lines
+   SPC c u     | uncomment lines
+   SPC c p     | toggle paragraph comments
+   SPC c P     | comment paragraphs
+   SPC c s     | comment with pretty layout
+   SPC c t     | toggle comment on line
+   SPC c T     | comment the line under the cursor
+   SPC c y     | toggle comment and yank
+   SPC c Y     | yank and comment
+   SPC c $     | comment current line from cursor to the end of the line
+<
+Tip: `SPC ;` will start operator mode, in this mode, you can use a motion
+command to comment lines. For example, `SPC ; 4 j` will comment the current
+line and the following 4 lines.
+
+UNDO TREE
+
+Undo tree visualizes the undo history and makes it easier to browse and switch
+between different undo branches. The default key binding is `F7`. If `+python`
+or `+python3` is enabled, mundo will be loaded, otherwise undotree will be
+loaded.
+
+Key bindings within undo tree windows:
+>
+  key bindings    | description
+  --------------- | -------------------
+   G              | move bottom
+   J              | move older write
+   K              | move newer write
+   N              | previous match
+   P              | play to
+   <2-LeftMouse>  | mouse click
+   /              | search
+   <CR>           | preview
+   d              | diff
+   <down>         | move older
+   <up>           | move newer
+   i              | toggle inline
+   j              | move older
+   k              | move newer
+   n              | next match
+   o              | preview
+   p              | diff current buffer
+   q              | quit
+   r              | diff
+   gg             | move top
+   ?              | toggle help
+<
+MULTI-ENCODINGS
+
+SpaceVim uses utf-8 as the default encoding. There are four options for this:
+
+  1. fileencodings (fencs): ucs-bom,utf-8,default,latin1
+  2. fileencoding (fenc): utf-8
+  3. encoding (enc): utf-8
+  4. termencoding (tenc): utf-8 (only supported in Vim)
+
+To fix a messy display: `SPC e a` is the mapping to auto detect the file
+encoding. After detecting the file encoding, you can run the command below to
+fix it:
+>
+  set enc=utf-8
+  write
+<

+起源于 2016 年 12 月份，目前主要由 [Eric Wong](https://wsdjeg.net) 在维护。
-早期的模块化配置理念来源于 airline 作者的 Vim 配置。
+
-进一步受到 spacemacs 的 layers 这一概念的影响，最终形成了最早期的版本。
