Simplified notation for avoiding the [weak self]/strongSelf dance with closures

• Proposal: TBD
• Author: Evan Maloney
• Status: Draft

Introduction

Frequently, closures are used as completion callbacks for asynchronous operations, such as when dealing with network requests. It is quite common to model these sorts of operations in such a way that an object instance represents a request/response transaction, for example:

function -d "Fuzzy change directory"  fcd
    if set -q argv[1]
        set searchdir $argv[1]
    else
        set searchdir $HOME
    end

    # https://github.com/fish-shell/fish-shell/issues/1362
    set -l tmpfile (mktemp)
    find $searchdir \( ! -regex '.*/\..*' \) ! -name __pycache__ -type d | fzf > $tmpfile

        //get the storyboard the ViewController under test is inside
        let storyboard: UIStoryboard = UIStoryboard(name: "Main_iPhone", bundle: nil)

Vim without NERD tree or CtrlP

I used to use NERD tree for quite a while, then switched to CtrlP for something a little more lightweight. My setup now includes zero file browser or tree view, and instead uses native Vim fuzzy search and auto-directory switching.

Fuzzy Search

There is a super sweet feature in Vim whereby you can fuzzy find your files using **/*, e.g.:

:vs **/*<partial file name><Tab>
