Using MSYS2 with Visual Studio Code

Using MSYS2 with Visual Studio Code is extremely easy now thanks to the Shell Launcher extension by Tyriar.

First, install the extension and reload Visual Studio Code.

Then, open the settings.json to edit your settings.

Add the field shellLauncher.shells.windows. I recommend using autocompletion here so that all the default shells are added.

You should having something like this now:

Debug zsh startup time

Debug zsh startup time

  1. Inject profiling code

    At the beginning of your .zshrc add following: zmodload zsh/zprof

    and at the end add: zprof

    This will load zprof mod and display what your shell was doing durung your initialization.

An iTerm2 Cheatsheet

In the below keyboard shortcuts, I use the capital letters for reading clarity but this does not imply shift, if shift is needed, I will say shift. So + D does not mean hold shift. + Shift + D does of course.

Tabs and Windows

Function Shortcut
New Tab + T
Close Tab or Window + W (same as many mac apps)
Go to Tab + Number Key (ie: ⌘2 is 2nd tab)
Go to Split Pane by Direction + Option + Arrow Key
