1. How to vim
author: Marcin Rogacki <mrogacki@nexway.com>, <rogacki.m@gmail.com>
experience in vim: 6 months

2. Why try?
1. Successfully used as IDE by others.
2. Don’t need X enviroment (Production quick fix? No problem!)
3. Lightweight & fast.
4. Able to edit large files 50MB, 100MB, 1GB (Ok... search the 1GB file is
an horror but still is openable).
5. Code is written faster (with enough vim experience).
6. Your keyboard skills will be improved.

3. place of new recruits is to the proving ground
run shell command: vimtutor
training

4. Now time for ‘Missions’.
They show practical tricks (at least I have hope
that they are practical) or just examples how to
fight with vim.

5. Basics

6. ● move: hjklweb$0gGf
● edit: aiorxdvc
● search: /nf
● undo and redo: u, ctrl+r
● copy & paste: ypdx
combine all of above into “advanced basics”
don’t use arrows or mouse!

27. Macros

28. Armory
q - record macro (in fly!)
small but powerful

29. how to use macros
1. find some ‘regularities’
2. record macro by q and pick an <register> (e.g. ‘a’ key)
3. work as usual with vim
4. stop recording by q
5. set cursor at next ‘regularity’ <number of repeats>@<register>

30. output
input
Mission: add ‘irregular’ text
Accomplished: qakf(wyw0jf(pa,ESCF(wctrl+a0jq10@a
Before start ensure that cursor is set at 2-nd line, keys: ggj. Then just invoke this sequence.

38. Last words

39. 1. Vim is not better than other IDE's. It is different. There is advantages
and disadvantages e.g. I think native IDE will alwasy have better code
autocomplete.
2. Before grabbing a mouse, early try do it with keyboard. Power of vim
is: to be always ready for text typing.
3. Beginnings are difficult, but after time will appear the conditioned
response, in the other words copy&paste/movement/refactor will take
milliseconds.
