Vim is great. Despite its steep learning curve<\/a>\u00a0, it has many advantages and many loyal Vim followers will tell you that you should force yourself to use it.<\/span><\/span><\/p>\n

Personally I started using Vim when I was ssh-ing into the group servers or into my computer in department. In such scenarios, I could not open the IDEs with the nice GUIs \ud83d\ude41\u00a0However, as time passed, Vim started to grow on me. Now, I can list a few reasons why I think it is great, for example,<\/span><\/span>\u00a0it requires a small amount of memory to run, has a short start up time\u00a0and can handle large files pretty well.\u00a0<\/span><\/span><\/p>\n

Although, I am definitely not a Vim expert, I will tell you about some of the things I have added to my .vimrc<\/code>.<\/span><\/span>\u00a0The .vimrc<\/code> file is very handy for containing all your favourite settings, such as\u00a0key mappings, custom commands, formatting and syntax highlighting.<\/span><\/span> The file uses vimscript which is a programming language in itself. However, there is a lot of help online that tells you with what lines to add to your .vimrc<\/code>. I would recommend installing Vundle<\/a>\u00a0which is a Vim plugin manager.\u00a0<\/span><\/span><\/p>\n

Here I will list some cool things that I have discovered you can do with your .vimrc<\/code>.\u00a0 \u00a0It has certainly made\u00a0my life a bit nicer. <\/span><\/span><\/p>\n

    \n
  1. Code Folding<\/strong>
    \nMost IDEs provide a way to collapse functions and classes that results in only seeing the function\/class definition and hiding the code. To do this in Vim add the following lines to your .<\/code><\/span><\/span>vimrc<\/span><\/span>\u00a0<\/span><\/span><\/code><\/code><\/code><\/p>\n
    \" Enable folding\r\nset\u00a0foldmethod=indent\r\nset\u00a0foldlevel=99\r\n\" Enable folding with the spacebar\r\nnnoremap\u00a0<space> za<\/pre>\n
    <\/code><\/code>
    \nAlternatively, you can install the Vim plugin     SimpylFold<\/a>.<\/span><\/span><\/li>\n
  2. Python indentation<\/strong>
    \nVim does not do auto indention like many IDEs. To automatically do PEP-8 indentation for Python, add the following to your .<\/span><\/span>vimrc .\u00a0<\/span><\/span>
    \n<\/span><\/span><\/span><\/p>\n
    \" PEP indentation\r\nau\u00a0BufNewFile,BufRead\u00a0*.py\r\n\\ set\u00a0tabstop=4\u00a0 \u00a0 \r\n\\ set\u00a0softtabstop=4\u00a0\u00a0\u00a0 \r\n\\ set\u00a0shiftwidth=4\u00a0\u00a0\u00a0 \r\n\\ set\u00a0textwidth=79\u00a0\u00a0\u00a0 \r\n\\ set\u00a0expandtab\u00a0\u00a0\u00a0 \r\n\\ set\u00a0autoindent\u00a0\u00a0\u00a0 \r\n\\ set\u00a0fileformat=unix\r\n<\/pre>\n
    <\/code><\/p>\n
    You can also install the Vim plugin\u00a0vim-flake8<\/a>\u00a0which is a static syntax and style checker for Python source code. It shows errors in a quickfix window and lets you jump to their location inside your code.<\/span><\/span><\/span><\/span><\/li>\n
  3. Turn line numbers on<\/span><\/span><\/strong>\u00a0<\/span><\/strong>
    <\/span>Rather than typing in\u00a0<\/span><\/span>\u00a0<\/span>
    <\/span>:set nu<\/span><\/span><\/code>\u00a0<\/span><\/code>
    <\/span>every time you\u00a0<\/span><\/span>open<\/span><\/span>\u00a0your files. You can always have them turned on by\u00a0<\/span><\/span>adding :set<\/span><\/span>\u00a0nu to your .<\/code><\/span><\/span>vimrc<\/span><\/span><\/code><\/li>\n
  4. Autocompletion<\/span><\/span><\/strong>\u00a0<\/span><\/strong>
    <\/span>When I switch from PyCharm to Vim I feel a bit lost without the autocompletion however, after a quick search I found many are using the Vim package\u00a0<\/span><\/span>    Youcompleteme<\/span><\/span><\/a>\u00a0and it is awesome.\u00a0<\/span><\/span><\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
