iarna

Times are off of my Linux laptop.

You can run with: ```console $ npx https://gist.github.com/acfba145e421d51c4de2cdb7faa3f309.git

With default config, using node_modules, which has 1295 files (6.6M):

```console
$ node benchmark.js

iarna

// render thread
// index
// record indexes of natural line breaks
//   record indexs of wrapped line breaks w/ predefined width
// display (line start, #lines, width)

const fs = require('fs')
let exampleText
let lineBreaks = []

iarna

made a folder called install-package-lock-only containing only a package.json with these contents:

{
  "name": "install-package-lock-only",
  "version": "1.0.0",
  "dependencies": {
    "mkdirp": "^0.3.4"
 }

These is a basic console capability test. Clone this repo (https://gist.github.com/58553b13c477de79069e.git) and use node cat console-test.txt to dump the test to your screen. (On Mac & Linux you can just use cat.) There's also a hide-cursor.txt and show-cursor.txt that should do what they say.

All of this is about me trying to figure out what actually is shared cross platform and what isn't.

What I've learned so far is:

iarna

npm and symlinks

npm link

→ Runs npm install and then symlinks the current module into your globals

npm link /path/to/thing

→ If thing is already in globals, unlink it.

iarna

Optimize for readability:

• Emphasize the important things.
• Demphasize the noise.
• Leave most of the content uncolored.

I emphasize:

• literals – light cyan
• constants - light green
• immutable operators - bright white
• mutating operators - yellow
