React Native utilizes flexbox for layout, and you can apply styles inline, or via external stylesheets. We will learn about both approaches, and create some basic styles for a native application.
For getting your application setup, you might want to checkout this lesson
Learn to use git grep to only search through the tracked files in a git repo. This is especially useful when you want to exclude build artifacts or locally installed dependencies, such as webpack bundles or the node_modules directory. You'll also note that git grep is automatically colorized - we'll see how to get the same coloring effect with grep --color.
Learn to use grep's extended regular expressions to describe more complex patterns. The
+ special characters describe optional patterns. The
? character matches zero or one instance of the preceding term, and the
+ character matches one or more instances of the preceding term. To use these characters, you'll need to either escape them with backslashes or turn on extended regular expressions with the
Describe optional patterns with grep OR using the vertical bar character
|. By using the
| special character, you can write either-or style patterns. In this lesson we'll look for matches on "grey" or "gray". Like the
? characters, the
| character is part of extended regular expressions with grep, so you'll either need to escape it with a backslash, or use the -E flag.
Learn to use the special anchor characters
$ to indicate the beginning and end of lines when writing regular expressions for grep. These line anchors are part of basic regular expressions in grep, so you don't need to escape them.
Learn to write components that render differently on iOS and Android, but present the same API. First, we'll use the Platform module to change behavior based on the platform. Then, we'll use the platform-specific file extensions, .ios.js and .android.js, to render platform-specific components.
It's a lot easier to manage your tmux session when they have sensible names. We'll cover:
Learn to organize your workspace using tmux. We'll create a new tmux session and learn how to create and navigate panes within a tmux window.
In tmux, a window is a collection of panes. Creating multiple windows is a great way to organize your workspace. In this lesson, we'll cover:
One non-obvious, but extremely useful, feature in tmux is copy-pasting text between panes. This also allows you to scroll back in a tmux sessoin. We'll cover how to use copy and paste in tmux using C-b [ and C-b ], for both emacs- and vim-style keybindings.
Do you have a standard workflow that involves setting up a specific tmux layout, or running certain commands? By writing tmux scripts, you can automate your tedious daily setup, while simultaneously documenting it for yourself. We'll cover the tmux command equivalents of common key bindings and write some simple, useful scripts.
In this lesson, we'll learn how to detach from a running tmux session and leave it running in the background. Then, we can re-attach to it later.
- How to exit a session by killing all active panes
- Detaching explicitly with C-b d
- Detaching a specific session with C-b D
- Viewing all running tmux sessions using tmux ls
- Reattaching with tmux attach -t
You can modify tmux's behavior with your tmux configuration file, .tmux.conf. You can use your tmux config to change color schemes, set custom keybindings, set defaults, modify the status bar, and more. In this lesson, we'll change some of the default color options as well as modify the prefix key.
In this lesson, we'll look at how to manage your history between tmux sessions, and ensure that your setup preserves your bash history between multiple windows. By adding a special PROMPT_COMMAND to your .bashrc, you can update and reload your history after every command, regardless of if you're in a different session, window, or tab.
