Links: Vim
Yes, Vim has grammar, and it probably is one of the most interesting parts about it, but if you didn’t like English at school don’t worry, you can also see this as a sort of programming language.
To understand this, we’ll divide Vim commands in 3 groups: Verbs, Modifiers and Nouns.
Verbs
This are mostly Editing commands
| command | description |
|---|---|
| x | delete character under cursor |
| r | replace character under cursor |
| c | change |
| y | yank (copy) |
| d | delete |
| p | paste |
| v | visually select |
Modifiers
| command | description |
|---|---|
| i | inside |
| a | around |
| NUM | any number (0,1,2..) |
| t | searches for something and stops before it (to —) |
| f | searches for something and lands on it (find) |
| / | find a string |
Noun
This are mostly Movement commands
| command | description |
|---|---|
| w | start of next word |
| b | start of previous word (before) |
| e | end of word |
| s | sentence |
| p | paragraph |
| t | tag (HTML) |
| b | code block |
| h,j,k,l | left, down, up, right |
| $ | end of line |
| 0 | start of line |
Make Sentences
You can use the number modifier with any command to repeat it set number of times. For example 2w will move the cursor two words instead of one.
Now with a verb, d2w will delete the current and next word.
Here you have some other examples:
| command | description |
|---|---|
| vap | Visually select this paragraph (visual around paragraph) |
| ci” | Change text inside quotes |
| ca” | Change text around quotes (includes quotes) |
| dt, | Delete text until the next coma on the current line |
| dj | Delete this and the line below |
| d/something | Delete text until the next search that matches “something” |
