Installation

npm i cornsol
# or
yarn add cornsol

Cautions

cornsol use the default naming for asynchronous.

If you want to use synchronous functions then use functions below.

function openPrintGroupSync<T>(fn?: () => T): T;
function closePrintGroupSync<T>(fn?: () => T): T;
function printStepSync<T = void>(stepName: string, stepFunction: () => T): T;
function printGroupSync<T = void>(stepFunction: () => T, open?: () => void, close?: () => void): T;
function printArraySync(fn: (msg: any, ...params: any[]) => void, messages: any[]): void;
function printBufferSync(fn: (msg: any, ...params: any[]) => void, chunk: any): void;

Usage

Register globally

const corn = require("cornsol");

corn.register();

// Unregister
corn.unregister();

Function supports

Overloads

• log
• debug
• dir
• info
• warn
• error
• group
• table
• trace
• groupCollapsed
• groupEnd

Extra features

• div
• array
• chunk

Group

Example

const corn = require("cornsol");

corn.register();

// Open and close the group manually
console.group("group start");
console.log("content");
console.groupEnd("close group");
// or
corn.openPrintGroup(console.log, "group start");
console.log("content");
corn.closePrintGroup(console.log, "close group");

Result

➤ 0000: ─ This is an example for print group
➤ 0001: ┌ group start
        │ content
        └ group end
➤ 0002: ┌ group start
        │ content
        └ close group

Array

Example

const corn = require("cornsol");

corn.register();

// Synchronous
console.array(["Item 1", "Item 2"]);
// or
corn.printArraySync(console.log, ["Item 1", "Item 2"]);

// Asynchronous
console.array.async(["Item 1", (async () => "Item 2")()]);
// or
corn.printArray(console.log, ["Item 1", (async () => "Item 2")()]);

Result

➤ 0000: ┌ Item 1
        └ Item 2

Step

Example

const corn = require("cornsol");

corn.register();

// Synchronous
const result = console.step("Step title", () => {
  console.log("Process 1");
  console.log("Process 2");

  return 1;
});
// or
const result = corn.printStepSync("Step title", () => {
  // ...
});

// Asynchronous
const result = console.step.async("Step title", () => {
  // ...
});
const result = corn.printStep("Step title", () => {
  // ...
});

console.log(result);

Result

➤ 0000: ┌ Step title step
        │ Process 1
        │ Process 2
        └ Completed in 0s
➤ 0001: ─ 1

Chunk

Example

const corn = require("cornsol");
const { exec } = require("child_process");

const proc = exec("ls");

corn.register();

// Synchronous
proc.stdout.on("data", console.chunk);
// or
proc.stdout.on("data", (chunk) => corn.printChunkSync(console.log, chunk));

// Asynchronous
proc.stdout.on("data", console.chunk.async);
// or
proc.stdout.on("data", (chunk) => corn.printChunk(console.log, chunk));

// It works internally like
corn.printArray(console.log, Buffer.from(chunk).toString().trim().split("\n"));

Result

➤ 0000: ┌ dist
        │ LICENSE
        │ node_modules
        │ package.json
        │ README.md
        │ src
        │ test
        │ tsconfig.json
        └ yarn.lock

Divider

Example

console.log("message 1");
console.div("This is a divider");
console.log("message 2");

// or

const { printDivider } = require("cornsol");

console.log("message 1");
printDivider("This is a divider");
console.log("message 2");

Result

➤ 0000: ─ message 1
───────── This is a divider
➤ 0001: ─ message 2

Customizations

cornsol supports customizing.

Spinners

cornsol use ASCII spinners on group print.

There are some presets for spinner.

// Built-in presets
export const spinners = [
  /* 0  */ "⣾⣽⣻⢿⡿⣟⣯⣷",
  /* 1  */ "←↖↑↗→↘↓↙",
  /* 2  */ "⠁⠂⠄⡀⢀⠠⠐⠈",
  /* 3  */ "▉▊▋▌▍▎▏▎▍▌▋▊▉",
  /* 4  */ "▁▂▃▄▅▆▇█▇▆▅▄▃▂▁",
  /* 5  */ "▖▘▝▗",
  /* 6  */ "┤┘┴└├┌┬┐",
  /* 7  */ "◢◣◤◥",
  /* 8  */ "◰◳◲◱",
  /* 9  */ "◴◷◶◵",
  /* 10 */ "◐◓◑◒",
  /* 11 */ "◡⊙◠",
  /* 12 */ "bᓂqᓄ",
  /* 13 */ "dᓇpᓀ",
  /* 14 */ "d|b|",
  /* 15 */ "q|p|",
  /* 16 */ "ᓂ—ᓄ—",
  /* 17 */ "ᓇ—ᓀ—",
  /* 18 */ "|/—\\",
];

// Update config
const corn = require("cornsol");

corn.configure({
  spinner: {
    symbols: corn.spinners[4], // "▁▂▃▄▅▆▇█▇▆▅▄▃▂▁"
  },
});

Line numbers

Example

const corn = require("cornsol");

corn.register();

corn.configure({
  formatters: {
    lineNumber: (context) => `${String(context.lineNo).padStart(2, "0")} [${new Date().toISOString()}]:`,
  },
});

console.log(0);
console.log(1);
console.log(2);

Result

➤ 01 [2022-12-20T02:48:47.909Z]: ─ 0
➤ 02 [2022-12-20T02:48:47.909Z]: ─ 1
➤ 03 [2022-12-20T02:48:47.909Z]: ─ 2

Step messages

Example

const corn = require("cornsol");

corn.register();

corn.configure({
  formatters: {
    stepStart: (context, name) => `The cool step ${name}`,
    stepEnd: (context, name, duration) => `The cool step ${name} has been completed in ${context.duration(duration)}`,
  },
});

console.log(0);
console.log(1);
console.log(2);

Result

➤ 0000: ┌ The cool step Test
        │ 0
        │ 1
        │ 2
        └ The cool step Test has been completed in 0s 1ms

Symbols

Example

const corn = require("cornsol");

corn.register();

corn.configure({
  symbols: {
    prefix: "$",
    singleLine: "*",
    newLine: "&",
    groupStart: "┳",
    groupLine: "┣",
    groupEnd: "┗",
  },
});

console.log(0);
console.log(1);
console.log(2);

console.group(0);
console.log(1);
console.log(2);
console.log(3);
console.groupEnd(4);

Result (small size terminal)

$ 0000: * 0
$ 0001: * 1
$ 0002: * 2
$ 0003: ┳ The cool step Test
        ┣ 0
        ┣ 1
        ┣ 2
        ┗ The cool step Test has been
