##INTRO: VERSION: 1.10

This is a vim keymap file contains mathematic symbols. with some effort to reduce typing conflict and increase typing speed.

Also contains a keyhelper for help inputting.

  • Superscript and Subscript :

      `0 ⁰  `+ ⁺ ... ( 0-9 + - ( ) / ^ . , > < )
      `a ᵃ  `A ᴬ ... ( a-z except q , Some of A-Z)
    
      _0 ₀  _+ ₊ ... ( 0-9 + - ( ) / ^ )
      _a ₐ  _e ₑ ... (a e h i k l m n o p r s t u v x)

  • Latex CMD:

      Based on Vim-Latex suite.
      Only contains latex command which have corresponding unicode chars.
      Fixed some incorrect mapping of Vim-Latex suite:
      (\bigodot \bigoplus \bigotimes \long...arrow \iint ...)
    
      e.g: 
          \neq     => ≠  ,  \Leftarrow =>  ⇐
          \simeq   => ≃  ,  \Re        =>  ℜ
          \mathbbA => 𝔸  ,  \mathfrakA =>  𝔄
          ...
    
      You can use Vim-Latex suite to check these command.
      or this pdf of math symbols.
      http://amath.colorado.edu/documentation/LaTeX/Symbols.pdf 
    
  • Key Helper(:KeyHelper):

      KeyHelper makes viewing and inputting these symbols easier.
    
      :KeyHelper to open the window.
      It will dynamicly showing matching keymap with your input.
      And press '<Enter>' in the KeyHelper window to append character to file.
    
      And you can input more unicode symbols:
      0x2500-0x2800,  0x1D100 - 0x1D1DD
    

HOW TO USE:

Extract to your ~/.vim folder.

  • You can make a mapping to use it easyier:

      " use it
      map <leader>km :set keymap=mathematic<CR>
      " stop use it
      map <leader>kn :set keymap=<CR>
      " view it's details, modify it at your convenience.
      map <leader>kvm :sp ~/.vim/keymap/mathematic.vim<CR>
    
      " show inputting cmd:
      " set showcmd
      " when a longer time for inputting is needed:
      " set timeoutlen=3000
      " or disable inputting timeout:
      " set notimeout
    

':h keymap' for further details.

  • Using KeyHelper: (:KeyHelper (<leader>\))

      " if your mathematic.vim is not in '~/.vim/bundle/' or '~/.vim/keymap'
      " then you should set g:mathematic_user_dir
      " let g:mathematic_user_dir = "~/.vim/myplug/keymap/mathematic.vim"
      " map KeyHelper with another mapping
      " nmap <leader>kk :KeyHelper<CR>
      " if you want fuzzy matching
      " let g:mathematic_fuzzymatch = 1

To request adding keymap CMDS , please post CMD and Character.

TODO:

  • add more symbols
  • add more descrptions.
