My terminal configurations

Bruce's Ultimate Perl Vim Configuration

Vim App

• Save (write): :w
• Save All: :wa
• Save All + quit: :wqa
• Quit: :q
• Quit (no save): :q!
• Quit+Save: :wq
• Quit all: :qa
• Quit all no save: :qa!

Note: You can use Ctrl-z to put vim in background, and fg command to put vim back to foreground.

Tip: execute any bash command via :!. For example, quickly change the permission of your current file via :!chmod +x %.

Navigation

Open Files by Name

• Search files by name: <c-p>, in CtrlP:
  • Switch filename/fullpath search only: <c-d>
  • next/previous string in the prompt's history: <c-n>, <c-p>
  • regex mode: <c-r>
  • cycle modes: <c-f> <--> <c-b>
  • search buffers: \b
• Toggle NERDTree: F5, in NERDTree:
  • Scope to directory: C
  • Go up one directory: U
  • go to parent: p
  • set working directory: cd inside NERDTree
  • search folder by name: /foo and ?foo as you would normally search in a file
  • create/delete file/folder: m
  • refresh tree: r

Jump to Definition

You need to have ctags configured

• Go to definition: ctrl-], ctrl-t to go back
• Navigate around jumps: ctrl-o <--> ctrl-i

In File

• Character: h j k l
• Word/WORD: bB <--> wW
• Line: 0 <--> $
• First char of line: ^
• Prev/Next occurence of word under cursor: # <--> *
• Page: ^d v--^ ^u

Code Outline

Launch TagBar: <F8> In Tagbar:

• Jump to file without closing the panel: p
• Go to area and close panel <cr>

Buffers

• Properly close buffer: \w
• Close all buffers but this: \aw
• Go to buffer :b1, where 1 is buffer id
• Next buffer: bn
• Previous buffer: bp

Error Checking

Errors then show up in the location panel, which you can open :lopen and close :lclose.

Editing Code

Code Commenting

• comment line: \cl
• minimal comment block: \cm
• uncomment line/block \cu
• append comment: \cA

Search/Replace in Files

Within file

• Search: ?foo <--> /foo, on [enter], press N <--> n to jump between matches
• • Clear search highlight: :noh
• Replace: :%s/source/target/gcI
  • % search whole file
    • '<,'> search selection (visual select)
    • default to search current line
  • c asks for confirmation, default to replace all
    • on c+[enter], y n to replace, q to stop
  • I case sensitive, default to insensitive

In visual mode:

• search selection: <c-l>
• search+replace selection with confirmation: <c-r>

In normal mode:

• Search word under cursor: *

Across files (Using CtrlSF)

Toggle search panel: \t

CtrlSF Arguments

• -R - Use regular expression pattern.
• -I, -S - Search case-insensitively (-I) or case-sensitively (-S).
• -C, -A, -B - Specify how many context lines to be printed, identical to their counterparts in Ag/Ack.
• -W - Only match whole words.

In insert mode:

• search something: \f
• search word under cursor: \n

In visual mode:

• search selection: \f

Copy Pasting

Within Vim

copy (yank): y paste: p

Outside Vim

Copy the whole file: leave vim and use cat filename, then copy from terminal.

If your vim doesn't copy to clipboard, a hack is to copy from the terminal. <F3> disables mouse input and line numbers, but allows you to select the text to copy. Press <F3 to toggle back again.

Selecting

Select inner block of matching brace: vi{

• { can replaced with (, ', ", [
• use va{ if you also want to include the brace

Column select: ctrl-v Line select: V

Code Folding

Define Folds

• Fold visual select: zf
• Fold all within {} block: zfa{
• Delete fold: zd

Using Folds

• close/open fold zc/zo
• close/open all folds: zM/zR

Change Settings

Edit .vimrc: \\r Source .vimrc: \r

Neat Commands

• Execute perl tidy on current file: :Tidy (usually you won't need to do this because saving the file executes perl tidy)
• Open terminal: :vert term, <c-w> :q to close
• Search perl-doc: either :Perldoc commandname or K on keyword.
• Remove trailing whitespaces :FixWhitespace

Tmux

• :set-window-option -g mode-keys vi - vi or emacs (default) mode
• :set-option mouse off - turns off mouse mode so you can copy paste
• ] - paste from tmux buffer
• % - split horizontal
• " - split vertical
• , - rename window
• I - install plugins

Copy Paste Mode

In mouse mode, scroll to enter

• / v--^ ? - find in window (vi)
• c-s v--^ c-r - find in window (emacs)
