Support

Support the development of Chromafi by becoming a patreon.

Features

* JavaScript objects that are logged to the console... still look like JavaScript objects.
* Chromafi highlights JavaScript functions.
* Adjust indentation for tabbed code with Chromafi.
* User defined color palettes.
* Line numbers optional.
* Padding adjustment for use with background colors or tight spaces.
* Chromafi also highlights strings of code in 176 languages.

Usage

``javascript
const chromafi = require('chromafi')

const obj = {
foo: 'bar',
baz: 1337,
qux: true,
zxc: null,
'foogle-bork': function (a, b) {
return b - a
}
}

const chromatastic = chromafi(obj)

console.log(chromatastic)
`

`javascript
const chromafi = require('chromafi')

function add (a, b) {
return a + b
}

const chromantic = chromafi(add)

console.log(chromantic)
`

$3

`javascript
const chromafi = require('chromafi')

const codeString =
// Creates a Class based on Type
const create = (kind, parent) => {
// Create the Class based on the Type's
// Constructor or use an Anon. Func
const protoclass = kind.ctor || function () {}

// Inherit from a parent object
if (parent) {
protoclass.prototype = new Parent()
}

// Merge prototype from Class's Type
if (kind.proto) {
merge.call(protoclass.prototype, kind.proto)
}

return protoclass
}

const chromadactic = chromafi(codeString)

console.log(chromadactic)
`

Options

`javascript
const chromafi = require('chromafi')
const chalk = require('chalk')

const obj = {foobar: 1337}

const options = {
lineNumberPad: 0,
codePad: 0,
indent: 2,
lineNumbers: true,
colors: {
base: chalk.bgBlack.white.bold,
line_numbers: chalk.bgCyan.black
}
}

const chromafanatic = chromafi(obj, options)

console.log(chromafanatic)

`

Light Color Scheme

Chromafi uses Chalk to write ANSI color codes to the terminal.

`javascript
const chromafi = require('chromafi')

const chromafi = require('.')
const chalk = require('chalk')

const obj = {
foo: 'bar',
baz: 1337,
qux: true,
zxc: null,
'foogle-bork': function (a, b) {
return b - a
}
}

const chromafantastic = chromafi(obj, {
colors: {
base: chalk.bgWhite.black.bold,
keyword: chalk.red,
number: chalk.blue.dim,
function: chalk.black,
title: chalk.blue,
params: chalk.black,
string: chalk.black,
built_in: chalk.blue,
literal: chalk.blue,
attr: chalk.black,
// Just pass chalk to ignore colors
trailing_space: chalk,
regexp: chalk.blue,
line_numbers: chalk.bgBlue.white
}
})

console.log(chromafantastic)
`

Highlighting Other Languages

Chromafi uses Highlight.js to syntax highlight to your code. This means Chromafi can highlight any language that Highlight.js can.

Let's Chromafi some assembler syntax:

`javascript
const chromafi = require('chromafi')

const armAssemblyCode =
.text

.global connect
connect:
mov r3, #2 ; s->sin_family = AF_INET
strh r3, [sp]
ldr r3, =server_port ; s->sin_port = server_port
ldr r3, [r3]
strh r3, [sp, #2]
ldr r3, =server_addr ; s->sin_addr = server_addr
ldr r3, [r3]
str r3, [sp, #4]
mov r3, #0 ; bzero(&s->sin_zero)
str r3, [sp, #8]
str r3, [sp, #12]
mov r1, sp ; const struct sockaddr *addr = sp

ldr r7, =connect_call
ldr r7, [r7]
swi #0

add sp, sp, #16
pop {r0} ; pop sockfd

pop {r7}
pop {fp, ip, lr}
mov sp, ip
bx lr

.data
socket_call: .long 281
connect_call: .long 283

/ all addresses are network byte-order (big-endian) /
server_addr: .long 0x0100007f ; localhost
server_port: .hword 0x0b1a

const chromalicious = chromafi(armAssemblyCode, {lang: 'arm'})

console.log(chromalicious)
