In this post, I am going to show you {when|how} to use Clojure marcos, ->> aka thread-last and -> aka thread-first. In some case, -> and ->> may perform the same operation if you do not pay enough attention. So I will also show you what's the difference between them. Note that doc -> and docs ->> din't make sense for me at first, so if same thing happened to you I hope that this post will make it clear.

If I am coding a function in Clojure, I would not think to write in macro firstly(maybe I am still new to it?). Macros like -> and ->> only come in my mind when it comes to refactoring. They are not neccessary in our program but they will make it elegant.

To explain how both of these macros work, let's us solve a quiz together.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

I use tmux splits (panes). Inside one of these panes there's a Vim process, and it has its own splits (windows).

In Vim I have key bindings C-h/j/k/l set to switch windows in the given direction. (Vim default mappings for windows switching are the same, but prefixed with C-W.) I'd like to use the same keystrokes for switching tmux panes.

An extra goal that I've solved with a dirty hack is to toggle between last active panes with C-\.

Here's how it should work:

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a
