TMUX

TMUX Cheat Sheet

I setup TMUX to work with nvim using vim-tmux-navigator, so my defaults for moving left, right, up, and down are vim defaults.

• Start tmux using tmux
• Think of windows as “screens” and panes as tabs
• Start tmux with name using tmux new -s name
• List tmux sessions: tmux ls
• Attach to a session: tmux a #
• Attach to a named session: tmux a -t name
• Kill a session: tmux kill-session -t name
• Kill tmux server: tmux kill-server
• Use Ctrl+hjkl to switch between panes
• Press Ctrl-a to prefix tmux keyboard shortcuts (remapped)
• % to split screen horizontally
• " to split screen vertically
• d to detach (leaving it running in background)
• x to kill current pane
• ? to list all keybindings
• { move current pane left
• } move current pane right
• o go to next pane
• z toggle full-screen mode for current pane

Vim

• Use i to do an action within a motion
  • e.g. ciw to change the word
• Use c to change within motion
• Use p to denote paragraph
• Use :set to access or modify values
  • Append option with ? to see the current value
• Buffers: an open file in memory
  • Three states:
    • Active: buffer is displayed in a window
    • Hidden: buffer exists, but is not displayed
    • Inactive: buffer is not displayed and does not link to a file
  • :buffers or :ls to list all the current buffers
    • Displays buffer ID, state, name, and cursor line
    • Hidden buffers won’t be displayed, either set hidden or append ! to command
  • Most buffer commands start with :b
    • :bn to move to next buffer
    • :bp to move to previous buffer
    • :bf to move to first buffer
    • :bl to move to last buffer
    • Ctrl-^ to switch to alternate buffer
    • Run command on all buffers: :bufdo <command>
    • Use :b <name> to switch to buffer with name using partial name matching
  • Create and delete buffers:
    • :badd <filename> adds <filename> to the buffer list
    • :bdelete <ID_or_name> deletes all buffers in <ID_or_name>
    • :%bdelete deletes all buffers
• Windows: where vim can display the content of a buffer
  • To create a new window use :new
    • CTRL-W s to split the current window horizontally
    • CTRL-W v to split the current window vertically
    • CTRL-W n to split the current window horizontally and edit a new file
    • CTRL-W ^ to split the current window with the alternate file (buffer with # indicator)
    • <buffer_ID>CTRL-W ^ split current window with <buffer_ID>
  • To switch between windows:
    • CTRL-W CTRL-W to switch to last (alternate?) window
    • CTRL-<hjkl> to move left, down, up, or right (remap)
  • To rotate windows:
    • CTRL-W r rotate the windows
    • CTRL-W x exchange with next window
  • To resize windows:
    • CTRL-W = resize windows to fit on screen with the same size
    • CTRL-W + increase window height
    • CTRL-W - decrease window height
    • CTRL-W < decrease window width
    • CTRL-W > increase window width
  • Exit windows with :q or :q! (these commands don’t quit vim, but quit a window!)
• To edit a new file use :e

Lua + Neovim

• Lua basics: honestly pretty similar to JS/Python

• comments are --, multi-line is two brackets [[comment here]]

• use if condition then for if statements

  • finish if statements with end

• blocks use do/end

• not equals is: ~=

• finish functions with end after return

• most everything else is either unimportant for what I care about right now, or something I’ll google

• Neovim lua config:

• To edit global settings, use the global variable/module vim

  • i.e. vim.opt.option_name = value

• lua/plugins.lua contains the config file for loading plugins
