Could you please provide a license. I am using quick-format and have just realised there is no license mentioned.

A repository link in package.json would also be appreciated.
#4 looks like a good option

This commit: 858729a

Causes this issue: pinojs/pino#983

Reproduction:

{
  "dependencies": {
    "qfu2": "npm:[email protected]",
    "quick-format-unescaped": "4.0.1"
  }
}

'use strict'

const assert = require('assert')
const qfu = require('quick-format-unescaped')
const qfu2 = require('qfu2')

const out1 = qfu(undefined, [])
const out2 = qfu2(undefined, [])

assert.equal(out1, out2)

If two %s is next to each other, the last one will be ignored:

var format = require('quick-format-unescaped')
format('%s%s', 'foo', 'bar') // => "foo%s bar"
format('%s %s', 'foo', 'bar') // => "foo bar"

Arguments are get skipped when %% is used:

const util = require('util');
const format = require('quick-format-unescaped');

console.log(util.format('test with %%: %s', 'foo')); // -> test with %: foo
console.log(format(['test with %%: %s', 'foo'])); // -> test with %: %s

console.log offers %f and %i as replacements which are unsupported by this package.
%f is an alternative to %d where %i floors the numeric value.

e.g.

console.log('%f', 42.9) //> 42.9
console.log('%i', 42.9) //> 42

Is it a goal of this lib to support those replacements?

currently if an object has a circular reference the whole object is serialized as: [Circular]

This is a problem, first if the intended JSON is a key or some other stringify JSON it's going to cause an error on parse (since [Circular] isn't quoted) - second all other non-circular properties on the object are lost

we could use json-stringify-safe but this double or triples the benchmarks, so we need a faster version of json-stringify-safe

I met this issue when I test with pino.
I noticed there is a similar issue #18
But it seems there are still some other issues when a format string next to one another.

The detail would be

const format = require('quick-format-unescaped')

console.log(format('%d%d', [11, 22]));
console.log(format('%d%s', [11, 22]));
console.log(format('%d%o', [11, { aa: 22 }]));
console.log(format('%d%d%d', [11, 22, 33]));
console.log(format('%d%d%s', [11, 22, 33]));
console.log(format('%d%o%d%s', [11, { aa: 22 }, 33, 'sss']))
console.log(format('%d%%%d', [11, 22]));
console.log(format('%d%%%s', [11, 22]));
console.log('\n');
console.log(format('%s%d', [11, 22])); // 
console.log(format('%s%s', [11, 22]));
console.log(format('%s%o', [11, { aa: 22 }]));
console.log(format('%s%d%d', [11, 22, 33]));
console.log(format('%s%d%s', [11, 22, 33]));
console.log(format('%s%o%d%s', [11, { aa: 22 }, 33, 'sss']))
console.log(format('%s%%%d', [11, 22]));
console.log(format('%s%%%s', [11, 22]));

These produce:

11%d
11%s
11%o
11%d22
11%d22
11%oNaN%s
11%%d
11%%s


1122
1122
11{"aa":22}
1122%d
1122%s
11{"aa":22}33%s
11%22
11%22

fast-safe-stringify is now on 2.0.7 and it would be nice to update to use it

• https://www.npmjs.com/package/quick-format-unescaped
• https://www.npmjs.com/package/quick-format

They're using the same git repo https://github.com/davidmarkclements/quick-format.

I have some problem with format. This is not convenient for testing

Example:

let util = require('util');
let format = require('quick-format-unescaped');

let a = util.format('foo %o', {name: "alex"}); // foo { name: 'alex' }
let b = format('foo %o', [{name: "alex"}]); // foo {"name":"alex"}

a === b // false

Is it possible add option for change formatting?

I've used pino logger and found that interpolated messages get escaped. So, it happens here.

const util = require('util');
const format = require('quick-format-unescaped');

console.log(util.format('test: %s', 'with \"qoutes\"')); // -> test: with "qoutes"
console.log(format(['test: %s', 'with \"qoutes\"'])); // -> test: with \"qoutes\"

I recently upgraded to the latest version of pinojs, which pulls in this library. In the previous version of pino, I could do something like this:

log.info('Uhoh, an error occurred:', err);
--or--
log.info('This object was just received', { some: 'object', with: 'values' });

Which would print the string + the provided object/arguments.

I see that in quick-format-unescaped v4, this was changed to not work without using the format: log.info('This object was just received %s, { some: 'object', with: 'values' });, which ends up breaking a lot of logging code that I had.

@davidmarkclements could you elaborate what the purpose was for this change? (i.e. 7113010)

Or, is there some workaround?
