New Mac Setup Notes

Install Xcode and the Xcode Command Line Tools.

Upgrade the shell to Oh My Zsh.

sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
Open ~/.zshrc

Change:
ZSH_THEME=”robbyrussell”
To:
ZSH_THEME=“gnzh”

Note: zsh aliases git to ‘g’

Setup Git Aliases

Open ~/.gitconfig (or create it if it doesn’t exist). Add:

[alias]
aliases = !git config –list | grep ^alias\\. | cut -c 7- | grep -Ei –color \”$1\” “#”
co = checkout
st = status
adds = “!f() { git ls-files –modified | grep “\\.swift$” | xargs git add; }; f”
addm = “!f() { git ls-files –modified | grep “\\.m$” | xargs git add; }; f”
addh = “!f() { git ls-files –modified | grep “\\.h$” | xargs git add; }; f”
addsb = “!f() { git ls-files –modified | grep “\\.storyboard$” | xargs git add; }; f”
addproj = “!f() { git ls-files –modified | grep “\\.pbxproj$” | xargs git add; }; f”
appcode = “!git ls-files –modified | grep “\\.xcscheme$” | xargs git co”
l = log –name-status

Setup git ignore file list (Usually ~/.gitignore_global but check via git config --list --show-origin)

If no ignore files are present create one and link it to git: i.e. git config --global core.excludesfile ~/.gitignore_global

Edit the file to include the following lines:

*~
.DS_Store

##Cocoapods
Pods/*
Podfile.lock

## User settings
xcuserdata/

Install Homebrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

• Objective-C

   brew install clang-format
  

  Download the Xcode code formatting plugin and open it. Set the formatting of your choice within the tool. Mine (similar to a workplace who’s coding convention I liked) is here:

   AlignAfterOpenBracket: true
   AlignConsecutiveAssignments: false
   AlignConsecutiveDeclarations: false
   AlignEscapedNewlinesLeft: true
   AlignOperands: true
   AlignTrailingComments: true
   AllowAllParametersOfDeclarationOnNextLine: true
   AllowShortBlocksOnASingleLine: false
   AllowShortCaseLabelsOnASingleLine: false
   AllowShortFunctionsOnASingleLine: false
   AllowShortIfStatementsOnASingleLine: false
   AllowShortLoopsOnASingleLine: false
   AlwaysBreakBeforeMultilineStrings: false
   AlwaysBreakTemplateDeclarations: true
   BraceWrapping : {
     AfterClass: true,
     AfterControlStatement: false,
     AfterFunction: false,
     AfterObjCDeclaration: false,
     AfterStruct: true,
     AfterUnion: true,
     BeforeCatch: false,
     BeforeElse: false,
   }
   BinPackArguments: false
   BinPackParameters: false
   BreakBeforeBraces : Custom
   BreakBeforeTernaryOperators: false
   BreakConstructorInitializersBeforeComma: false
   BreakStringLiterals: true
   ColumnLimit: 0
   IndentWidth: 4
   IndentCaseLabels: true
   KeepEmptyLinesAtTheStartOfBlocks: false
   MaxEmptyLinesToKeep: 1
   ObjCBlockIndentWidth: 4
   ObjCSpaceAfterProperty: true
   ObjCSpaceBeforeProtocolList: true
   PointerAlignment: Right
   ReflowComments: true
   SortIncludes: false
   SpaceAfterCStyleCast: false
   SpaceBeforeAssignmentOperators: true
   SpaceBeforeParens: ControlStatements
   SpaceInEmptyParentheses: false
   SpacesBeforeTrailingComments: 1
   SpacesInAngles: false
   SpacesInCStyleCastParentheses: false
   SpacesInContainerLiterals: false
   SpacesInParentheses: false
   SpacesInSquareBrackets: false
   TabWidth: 4
   UseTab: Never
  

  Go to your system’s System Preferences → Extensions

  Verify that clang-format in the Xcode Source Editor section is checked.

  To setup a keyboard shortcut, open System Preferences, click Keyboard, and switch to the Shortcuts tab.

  On the left column, select App Shortcuts, then hit the + button. Select Xcode, enter Format Source Code, and define a shortcut. I use option-command-l.
