Using vim faster than the other guy

Quick tech talk about vim usage, and how be more efficient doing it.

Transcript

1. Using vim faster than the other guy Quick tips to master vim
2. Remaps your caps lock to control! You can thank me after a month using it. :) ∴ QUICK TIP OF EFFICIENCY
3. ∴ LET’S TALK ABOUT VIM
4. ∴ VIM MODES • VIM is a MODAL Text Editor, and the most important modes are: • Normal Mode • Insert Mode • Visual Mode
5. ∴ WHERE TO START • Always start mastering Normal mode from: • Unshifted keys • Shifted keys • Control keys • Looking to your keyboard, do you know what each key do in Normal Mode?
6. ∴ GETTING HELP
7. ∴ GETTING HELP MOTION
8. ∴ MOTION COMBO
9. ∴ WHAT JUST HAPPENED? I searched for the word baixar From normal mode I typed /baixar
10. ∴ WHAT JUST HAPPENED? As soon I got there I typed cw which means change word
11. ∴ MOTION COMBO
12. ∴ WHAT JUST HAPPENED? For some reason I was in the middle of the baixar word, and then I typed change inside word
13. ∴ MOTION COMBO
14. ∴ WOW, WHAT JUST HAPPENED? If I want to get rid of the entire text block (paragraph). I simply type change inside paragraph
15. ∴ THAT REMEMBER US How destructive vim can be Watch out what you are typing
16. ∴ MOTION COMBO
17. ∴ WHAT JUST HAPPENED? If I want to change the content of a given tag. I just type change inside tag
18. ∴ TPOPE This is possible thanks to the surround.vim plugin, by Tim Pope <3
19. ∴ PRACTICE IS THE KEY Get all the keystrokes in your muscle memory, is the best thing you can do
20. ∴ MOVING BETWEEN LINES
21. ∴ MOVING BETWEEN LINES Using j and k to move between lines is tedious and very inefficient
22. ∴ MOVING BETWEEN LINES
23. ∴ MOVING BETWEEN LINES Well not tedious, but inefficient for sure. It is a nice to have, but that affect one principle when using vim
24. ∴ THAT PRINCIPLE I gonna talk about in a minute
25. ∴ MOVING BETWEEN LINES
26. ∴ MOVING BETWEEN LINES Now we are talking. Use 12j or 12k, it’s like 12 times faster than use j and k alone
27. ∴ MOVING BETWEEN LINES Nice, but when you have a file with hundred lines?
28. ∴ MOVING BETWEEN LINES
29. ∴ MOVING BETWEEN LINES Search is definitely the most efficient way to move between lines, it is fast and you don’t care about how many lines the file have
30. ∴ PRINCIPLE TO REMEMBER
31. ∴ PRINCIPLE TO REMEMBER Read is the worst thing you can do
32. ∴ PRINCIPLE TO REMEMBER Scan is a little bit better
33. ∴ PRINCIPLE TO REMEMBER But the best scenario is simply do
34. ∴ VIM IS ABOUT DRY TOO Whenever possible, don't repeat yourself
35. ∴ REPEATABLES
36. By deleting a line with dd, you should never repeat it with dd again ∴ REPEATABLES
37. ∴ REPEATABLES
38. ∴ REPEATABLES Delete the first line with dd, and then use dot . to repeat it over and over
39. ∴ REPEATABLES • For motion, normal mode and other commands you have dot . as repeatable • For substitute command :s// you have & as repeatable • For search command / you have n to search next word and N for the previous • For visual lines you have :’<,'>mode to run some mode commands on each selected line • When search a character with f you can go back and forth with , and ;
40. ∴ FILE NAVIGATION Vim doesn’t have a decent file navigation system
41. ∴ FILE NAVIGATION
42. ∴ FILE NAVIGATION I would hang myself if I had to navigate between files this way
43. ∴ FILE NAVIGATION Thanks to the community we have a plenty options available
44. ∴ FILE NAVIGATION • Tree directories • NERDTree • For fuzzy search • Command-T (sucks because depends on ruby) • Selecta (again depends on ruby) • Ctrl-p (awesomeness is pure Vimscript)
45. ∴ FILE NAVIGATION
46. ∴ FILE NAVIGATION NERDTree, what is it good for?
47. ∴ FILE NAVIGATION Well, if you are new in a project and don’t have all directories and files in mind
48. ∴ FILE NAVIGATION
49. ∴ FILE NAVIGATION Definitely the best, just like the ctrl-p on Sublime
50. ∴ FILE NAVIGATION We can improve that even further
51. ∴ FILE NAVIGATION
52. ∴ FILE NAVIGATION Starting directly from the app/views the fuzzy search became faster to match a given view
53. ∴ FILE NAVIGATION • Rails Projects • <leader>cv app/views • <leader>cm app/models • <leader>ct app/controllers • <leader>cs spec/ • VivaReal Site • <leader>va src/main/webapp-resources/assets • <leader>vm src/main/webapp/mustache
54. ∴ FILE NAVIGATION Common files such as Gemfile, routes.rb, Gruntfile.js and etc…
55. ∴ FILE NAVIGATION Map some keys to go directly to them, without take too much keystrokes
56. ∴ FILE NAVIGATION
57. ∴ FILE NAVIGATION The best scenario is to have the most used files mapped dynamically
58. ∴ FILE NAVIGATION For rails projects the super awesome vim-rails plugin does
59. ∴ CONTROLLER - SPEC
60. ∴ CONTROLLER - VIEW
61. ∴ VIEW - PARTIAL
62. ∴ CONTROLLER - MODEL
63. ∴ MODEL - SCHEMA
64. ∴ FILE NAVIGATION • Most used commands • :A (Alternative) - Switch between controller and spec • :R (Relative) - Switch between current cursor controller action to view • gf - Native vim go to file • <leader><leader> - remap it to <C-^>, which switch from the current buffer to the last opened
65. ∴ FILE NAVIGATION Just :A and :R are from vim-rails plugin, gf on normal mode is vim default behaviour. Such as <C-^>
66. ∴ REGISTERS Your IDE or Text Editor have a huge number of clipboards?
67. ∴ REGISTERS On vim you can easily have more than 30 clipboards, including the system clipboard
68. ∴ REGISTERS Look at your keyboard, if it’s not a modifier key can be a register
69. ∴ REGISTERS They are not just clipboards, you can use registers to record a series of keystrokes creating a macro
70. ∴ REGISTERS
71. ∴ MACROS
72. ∴ NON DUMB WAY
73. ∴ JUST OUT OF CURIOSITY You know what grep mean?
74. ∴ JUST OUT OF CURIOSITY Where he came from?
75. ∴ JUST OUT OF CURIOSITY From vim, of course
76. ∴ JUST OUT OF CURIOSITY From command mode :g/re/p
77. ∴ JUST OUT OF CURIOSITY Which means :global/regularExpression/print :g/re/p grep
78. ∴ EXAMPLE
79. ∴ EX MODE The best mode to edit css or any other sentence that repeats over and over
80. ∴ EX MODE
81. ∴ VIM IS HUGE There is a lot more to cover, and this talk couldn’t satisfy all vim aspects
82. ∴ JUST REMEMBER • Learn normal mode keys • Motion commands • Don’t Repeat Yourself • From lowest to fastest: Read > Scan > Do • Get help from vim or from community • Use vim and have fun
83. ∴ THANK YOU!
