My shell setup

I use this repo to have a similar shell experience in different computers on mac os x and for some helpful shortcuts and commands.

Note: this used to be my vim config, but I've mostly stopped using plain vim for code and it was really out of date anyway - the most useful parts for me were the shell commands and shortcuts, so I'm mostly maintaining those now

Setup

Clone this repo into home dir as .. eg. arnorhs-shell-config - (I'll refer to that name for the rest of this setup guide:

git clone git@github.com:arnorhs/vimrc.git ~/arnorhs-shell-config

Enabling shell defaults, shortcuts and gitconfig shortcuts

Really, these are disparate things - so you can pretty much pick and choose which of these things you end up using:

• zsh / bash defaults and shortcuts include shell-files from your local shell's rc file:

  source ~/arnorhs-shell-config/.zshrc

  or for bash:

  source ~/arnorhs-shell-config/.bash_profile

• gitconfig aliases and defaults Use the git/base.gitconfig file without changing/deleting your existing one (and thus allowing you to keep using your own user.name / user.email settings and allows for overriding anything else) - edit (or create) your ~/.gitconfig file and append the following:

  [include]
    path = arnorhs-shell-config/git/base.gitconfig
  

• gitconfig for delta aliases and defaults I started using git-delta to highlight my diffs. It adds way too much UI to the diffs in my opinion, so I'll probably tweak the settings with time, but you need to install it and then include:

  [include]
    path = arnorhs-shell-config/git/delta.gitconfig
  

• vim config Sym link config files for .vim

  ln -s ~/arnorhs-shell-config/.vimrc ~/.vimrc

Overview of stuff

git config

• Really good config trust me
• Mostly around not accidentally doing something nasty like disabling default git push without specifying a remote - this is really helpful if you are clumsy and have a lack of focus
• Sets a default of not changing line endings for repos that have horrble CRLF endings etc
• Some other things...

git aliases (many of these are copied from other places years ago...)

Note: A lot of people like to simply alias their bash commands for ie. gci for git commit etc - i personally don't like that and prefer that my git commands are all scoped under git - and if you feel like typing git before things, that's just a skill issue and you should work on your typing speed (the irony is not lost on me, with the majority of these commands relating to shortening things to type).

• Plain git xx shortcuts: co → checkout, ci => commit, st => status, br → branch
• git hist - prettier git history log printout - mostly useful when you have merge commits. most of the time I work with code that has linear history, so it's not really that useful to me anymore
• git fshow - prints out a full absolute path file listing of all the files changed in a particular commit/ref range - this is useful for passing into other commands and command line tools.
• git brr <number> - show the <number> of most recently used branches (I use this A LOT)
• git wip - adds everything in the working tree and commits it with the commit message "wip"
• git todo <ref> - finds all the things that have changed in your current branch that have a TODO:-style comment (prefixed by // unfortunately, so only works for things with those types fo comments) - When I'm working on a change, I like to add a bunch of TODOs all over the place to remind me of things I may forget to do - also helps with not going on tangents any time I see something. By default it compares to origin/master but you can supply the branch with the first argument
• git update <ref> - fetches and rebases the current branch on top of the provided branch. (the cool kids probably use git pull --rebase or something, but I haven't gotten around to getting used to that)
• git base - gives you the first parent commit that both the current branch and the master branch have - usefull for seeing changes compared to master when both have changes etc
• git basemain - same as git base but for origin/main - i haven't been bothed to see how plain git-aliases take in arguments
• git squash <ref> - starts interactive rebase squash against the <ref> - defaults to origin/master
• git amend - adds the working tree and commit-amends to the last commit without prompting for a commit message, also sets the date to now.

.zshrc specifics

• Sets the word-select and modifier key-word navigation to what I'm used to - jump between words with modifier keys + arrows
• Sets the prompt to eg. ~/arnorhs-shell-config % in blue - im used to that.
• Loads zsh-completions - if you have brew installed
• adds node_modules/.bin to your $PATH - makes it so you can use bin scripts in node_modules without typing out the full path to them and without prefixing them with bun/npm run/yarn/pnpm etc

aliases

Note: invoking functions and aliases is mostly the same thing, except for the behavior of aliases where you are still running the same command as something else, so you can generally append extra arguments etc - so that's better suited for cases where you just want to augment an existing command with some defaults.

And these defaults are pretty conservative for the most part - I hardly ever have to reach out for a normal grep for instance.

• g - grep ignoring most common things, defaults to case insensitive and recursive and prints the file & line number & highlights matches
• ls - ls with -laG
• ip - show your current local ip address - usefull because ifconfig gives you so many virtual interfaces
• gti - because i'm a dumbass

functions

• duf / dus - reasonably readable file size summary of the current dir
• removecontainers - force remove all docker containers
• armageddon - remove all docker containers, images, volumes and network interfaces
• wip - add & commit the current working tree and push to remote branch (errors if on main/master branch) - optionally supply a commit message other than "wip" (surround with quotes)
• port_kill - tries to find a process runnin on a particular port and tries to forcefully kill it - port is first argument
• port_list - list processes listening to a particular port - port is first argument
• jwtdecode - decode first argument as a jwt token

vimrc

If you really want to use vim, you should be using neovim anyways.

The config is mostly just some sane defaults copied from a bunch of places.
