vim

I have been actively using vim (technically ) for development at work and at home for almost 4 years (and was switching between between vim and atom the year before). I like it mainly because it allows me to use modal editing which is faster for me compared to or . Another reason is that almost all servers has either vi or vim available. One more reason is that I am pretty bad at using point-and-click interfaces and I would like to stick to command line tools as much as possible. Perhaps the most important reason, it looks cool to code in a terminal, isn’t it?

The learning curve of vim is pretty steep at the beginning. Luckily, I got myself a little head start by using . I then forked it and made . The way that I start learning vim is by going through and try to understand the mappings involved and try it out in vim. In retrospect, this is probably not the best way to start and I should have start with vimtutor and go through the basics instead. As many people have already suggested, I did not try to use it at work at the beginning as this would affect my productivity too much. After trying it out for 8-10 weekends with my hobby projects, I felt more confident with vim and tried to use vim and Visual Studio Code at work. After 3 or 4 months, I was getting more used to vim and use it solely at work. During this process, one of the things I have done to help myself learning more about vim is to consume a large amount of YouTube videos where people demonstrate their skills with vim. Here is a list of my favourite channels.

Besides YouTube videos, I learned quite a lot by reading through sub-reddits of and .

It is amazing that I can still learn something new about vim everyday now although I have been using it for more than 4 years full-time. The rest of this post is not meant to be a tutorial but rather showing what vim can do with some of my configuration and I hope this can inspire someone to use vim as their editor.

Apart from configuration, there are plug-ins to make life easier to use vim. There are many plug-in managers available. I inherited Jess Frazelle’s way of doing it by using from Tim Pope. I like this way of managing it as it is purely git operations (although everyone else is using which is good as well). The rest of this post is based on and many of the key bindings (or mappings) are not the same as the built-in ones.

If the following is too long a read for you, feel free to jump to .

Essentials

To be able to know what mappings are available is important for learning so that we would know what we can try. :Maps (with help of plug-in ) does exactly this.

File searching is also available using ctrl+p. It is like file search in any other editors or IDEs. Behind the scene, it is using fzf and .

^ can be used to jump to the first character of the current line.

$ can be used to jump to the end of the current line.

V can be used to visually select a line. Sometimes, one may want to select the previous visual select by gv. The following example visually select a bullet point, copy it, move the cursor somewhere else and select the paragraph again.

[s and ]s can be used to jump to the previous and the next spelling mistake respectively. When the cursor is on the spelling mistake, z= can be used show a list of suggested correct spellings. The following example jumps to the previous spelling mistake and take the first suggestion to fix it by [s1z=.

% can be used to jump between square bracket or parentheses surrounding the current cursor.

[{ and ]} can be used to jump to the previous and the next curly brackets respectively.

:jumps shows the list of locations of previous jumps made. ctrl+o and ctrl+i jumps to the previous and the next position respectively.

Editing

S starts cursor in the current line with correct indentation. It also wipes out the current line as well.

[+space and ]+space can be used to add empty line above and below the current line respectively. The following example uses 2[space to add to empty lines above the cursor.

[e and ]e swap the current line with the line above and below respectively. The following example demonstrates [e.

With cursor in parentheses of a method/function parameters, gs can be used to visually select a parameter and swap it. The following example selects the parameter to be swapped by using j and k, and the parameter is moved around by using h and l.

The same command can be used to swap a visually selected list as well.

Change operation can be pretty powerful. For example, 2ci( can be used to change all the text within two parentheses.

The above are some of the very basic stuff. I will cover more in the future blog posts.

Enjoy coding.
