每天一回一回的看，終於把Practical Vim看完了
不過到了後期，大部分就真的都看不太懂了＝ ＝
所以大多還是只記錄了前期我比較看得懂的一些 tip
Ch1: The Vim Way
Tip2: Don't Repeat Yourself
.command: Repeat the last change- Command in normal mode
- The insert mode between two normal mode
Repeatable action and how to repeat them
| Intent | Act | Repeat | Reverse |
|---|---|---|---|
| Make a change | . | u | |
| Scan line for next character | f | ; | , |
| Scan line for previous character | F | ; | , |
| Scan document for next match | /pattern<CR> |
n | N |
| Scan document for previous match | ?pattern<CR> |
n | N |
| Perform substitution | :s/target/replacement | & | u |
| Execute a sequence of changes | qx | @x | u |
Ch2: Normal Mode
Tip10: Use Counts to Do Simple Arithmetic
<C-a>: Add number<C-x>: Sub number- What if the cursor is not on a number?
- Operate on the number after the cursor
Combine and Conquer
- Operator + Motion = Action
- When an operator command is invoked in duplicate, it acts upon the current line (e.g. dd)
| Trigger | Effect |
|---|---|
| c | Change |
| d | Delete |
| y | Yank into register |
| g! | Swap case |
| gu | Make lowercase |
| gU | Make uppercase |
| > | Shift right |
| < | Shift left |
| = | Autoindent |
Ch3: Insert Mode
Tip13: Make Corrections Instantly from Insert Mode
If we make a mistake while composing text in Insert mode, we can fix it immediately
| Keystrokes | Effect |
|---|---|
<C-h> |
Delete back one character(backspace) |
<C-w> |
Delete back one word |
<C-u> |
Delete back to start of line |
The keystrokes above can also be used in bash shell
Tip14: Get Back to Normal Mode
<C-o> Switch to Insert Normal mode
Tip15: Paste from a Register Without Leaving Insert Mode
<C-r>0: Paste the text that we just yanked at the current cursor position
Tip19: Overwrite Existing Text with Replace Mode
R: Enter replace mode
Ch5: Command-Line Mode
Tip28: Execute a Command on One or More Consecutive Lines
- range
:{start, end}: from line "start" to line "end".: current line%: all lines
Tip31: Repeat the Last Ex Commands
@:: Repeat the last Ex command
Tip32: Tab-Complete Your Ex Commands
<C-d>: Reveal a list of possible completions
Tip33: Insert the Current Word at the Command Prompt
<C-r><C-w>: Get the word under cursor in Ex mode
Ch8: Navigate Inside Files with Motions
This chapter is extremely practical
Ch9: Navigate Between Files with Jumps
Tip55: Travel the Jump List
| Command | Effect |
|---|---|
[count]G |
Jump to line number |
//pattern<CR>/?pattern<CR>/n/N |
Jump to next/previous occurrence of pattern |
% |
Jump to matching parenthesis |
(/) |
Jump to start of previous/next sentence |
{/} |
Jump to start of previous/next paragraph |
H/M/L |
Jump to top/middle/bottom of screen |
gf |
Jump to file name under the cursor |
<C-]> |
Jump to definition of keyword under the cursor |
/ |
Jump to a mark |
Ch12: Matching Patterns and Literals
Tip74: Use the \V Literal Switch for Verbatim Searches
Put \V before words when searching can cancel regular expression
Ch13: Search
Tip81: Preview the First Match Before Execution
Use <C-r> <C-w> to autocomplete when searching
Ch14
Tip88: Find and Replace Every Match in a File
%s/word1/word2/g
