Dotfiles

Note that the .gitconfig assumes this repo is cloned to ~/tools/dotfiles, personal name and email are in ~/tools/.gitconfig_personal and that any work-related settings (basically just name and email) are in ~/repos/dotfiles/.gitconfig_work.

Tool usage

vim TIL

A very small list of useful vim commands. Assumes basic vim proficiency.

• jumplist: CTRL-o (older), CTRL-i/<Tab> (newer)
  • vim tracks jumps within windows, allowing navigation to and from previous files and positions
• CTRL-^
  • Edits the alternate file (usually the previously edited file). Useful as a toggle between two files.
• ZZ, ZQ
  • ZZ: :x; ZQ: :q!
• !, .!
  • !: shell from vim; .!: shell and forward output
• K
  • runs man for keyword under cursor
• #, *
  • # searches for keyword under cursor backward, * searches forward
• g
  • some cool examples
• :earlier and :later
  • :earlier 30m, :later 3h 22m
• gf
  • go to file. Works for local paths for python, javascript, etc.
• :Le(xplore)
  • Netrw explorer window with changes made to window to (right pane)
• reg(ister)
  • reg to access registers. If you yank and then yank again, your previous register is still stored!
  • "kyy to store a line in k, then "kp to paste. `k
  • Register : holds the last command, / the last search. .e.g. ":p to paste the last command, "/p the last search.`
• marks
• q:, q\
  • q: (or :CTRL-F) for command line w/ history, q\ (or \CTRL-F) for searches.
• CTRL-R CTRL-W, CTRL-R CTRL-0
  • Inserts the current word under the cursor and the most recent item yanked, respectively
• gqip
• :bd removes buffer from open buffers
• ctrl-x, ctrl-l
  • whole line completion
• changelist: g; (older), g, (newer)
  • vim tracks locations of changes, allowing jumps to those locations
• ctrl-r-w, ctrl-r-<register>
  • paste contents of current highlighted word / current register in insert and command-line modes
• H, M, L, zt, zz, zb
  • first three move cursor in current view, last three keep cursor but shift screen
  • also remember there is more than ctrl-u/d (ctrl-b/f/e/y)
• Reminder to use marks to copy/paste arbitrary chunks of code / across the screen (ma, d`a)
• :%! python -m json.tool
• cfdo: https://thoughtbot.com/blog/lists-vim-and-you
  • ctrl-a ctrl-q to put in quickfix list
  • :cfdo %s/snakeCase/snake_case/g | update to run over each file
  • :cdo %s/snakeCase/snake_case/g | update to run over each element
• Don't forget about vim unimpaired. i.e. [u and ]u encode and decode URLs
• Numbered lists:
  • ctrl-a increment / ctrl-x decrement under cursor or first occurence to right. Can add prefix e.g. 3 ctrl-a

vim todo

• Investigate :help changes
• Investigate vimux?
• Consider vim-sleuth
• Give vim-sneak another try (or vim-seek, commands like yrwp look interesting, so does clever-f, possibly)
• look up multilvel undo
• look up undofile
• cfdo

vim links I liked

• Productive shortcuts
  • Good primer of ex command set
• Good intro
  • e.g. good vim users more likely to use things like H, M, L, %, f, /, ]] than h, j, k, l, etc.

git

Basic git.

• clean: Remove untracked items. -f for files, -d for directories. Obliterates uncommitted unstages changes.
• reset: Unstages all files. Safe.
  • reset <file>: Unstage <file>. Safe.
  • reset <commit>: "Undo" commit, keeping files but unstaged, only to be used for local commits.
  • reset --hard: Reset staging and working directory to match the most recent commit. Obliterates uncommitted staged changes.
• revert <commit>: Generate new commit that undoes the changes introduced in <commit>, then apply it to the current branch.
• checkout <commit>: Update all files in the working directory to match the specified commit.
• checkout (<commit>) <file>: Check out a previous version of a file. This turns the <file> that resides in the working directory into an exact copy of the one from and adds it to the staging area.

• Undoing git changes

fish

Things I forgot:

• ctrl-f accepts autosuggestion (in addition to → but easier to type!)
• alt-→ accepts single word of autosuggestion
• Fish basics

tmux (with kitty I no longer use tmux)

• Intro to point people to
  • Basic key mappings and tmux functionality
