Chromafi

🦅 cli syntax highlighting: any function - any object - 176 languages

Fork notice

This is Truffle's customized fork of Chromafi. The original Chromafi can be found here.

The differences are as follows:

1. This fork allows colors to continue across lines.
2. This fork exposes the hljs object as chromafi.hljs so that it can be modified.
3. This fork uses lodash.merge instead of deepmerge for Webpack compatibility.
4. This fork has removed the ansi-mark functionality and dependency.

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

Chromafi a JavaScript Object

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)

Chromafi a JavaScript Function

const chromafi = require('chromafi')

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

const chromantic = chromafi(add)

console.log(chromantic)

Chromafi a String of Code

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

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.

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:

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)
