Previously, a string first argument was treated as a format string even if it did not actually contain format specifiers. Now it will only be treated as a format string when it contains format specifiers which is in line with the Console Standard.

Additionally, this eliminates output inconsistencies in the non-format-string case where elements were output differently depending on their position in the argument list.

Should we update this note with something like this:

If the first argument is not a string then... ->
If the first argument is not a string or it does not contain any format specifiers then...?

@vsemozhetbyt thanks, updated docs quite a bit to be more accurate and also renamed placeholders to format specifiers.
@cjihrig you sure about this semver-major label? All our current tests pass and I think the only real change is the escaping of ' in strings.

I think it's an edge case, but still needs to be treated as semver major just to be safe. Our own test suite has not been a great measuring stick in the past for these things. If others feel strongly that it's not semver major, feel free to remove the label.

On second thought, I'm fine with keeping it major.

From citgm, something changes independently of the first string parameter content:

 !!! Invalid input or expected stdout
 ---INPUT---
 {
     var o = {
         n: NaN
     };
     console.log(o.n == o.n, o.n === o.n, o.n != o.n, o.n !== o.n, typeof o.n);
 }
 ---EXPECTED STDOUT---
 false false true true 'number'
 ---ACTUAL STDOUT---
 false false true true number

Another one:

 ---INPUT---
 {
     var a = "32";
     !function() {
         var b = a + 1;
         !function(a) {
             console.log(a++, b);
         }(0);
     }();
 }
 ---EXPECTED STDOUT---
 0 '321'
 ---ACTUAL STDOUT---
 0 321

That may be because I use inspect instead of String on numbers, which I recall was necessary to get some of our own tests to pass. Will check.

Looks like the old implementation did use inspect on all arguments if the first argument is not a string. When first was a string, String was used on types other than objects and symbols.

Guess I have to reimplement this inconsistency for the sake of compatibilty.

I cannot fix above errors without re-introducing the issue that this was meant to fix.

Our current implementation of util.format outputs types other then object and symbol using String() when the first argument is a string. When the first argument is not a string, inspect is used on all arguments, which results in inconsistent output like this:

My implementation removes this inconsistency by always formatting arguments the same, regardless of their position in the argument list:

screenshot 2018-09-30 at 10 43 44

I think this is the best compromise we can do and it's worth the breaking change in the console output.

A even better way could be to run all types through util.inspect, but that would mean we'd have to remove string quotes and all strings in console output would become colored, which would probably break a ton of things.

Added a second changelog entry to clarify the details on the formatting change. If we disregard color, the only real difference in console/format output is on the arguments [nonstring, string] where previously, string would have been logged with quotes which are now gone.

Looks like this needs a rebase? :/

not replaced.
If a specifier does not have a corresponding argument, it is not replaced.

Values that are not part of the format string are formatted using

Yeah makes sense, I moved it after the code block.

util: treat format arguments equally
Two changes here which bring us closer to the console standard:

- Arguments to `util.format` are no longer formatted differently
  depending on their order, with format strings being an exception.
- Format specifier formatting is now only triggered if the string
  actually contains a format string.

Under the hood, we now use a single shared function to format the given
arguments which will make the code easier to read and modify.

I see your point, but I don't really like adding quotes. They change the content and are not transparent to dumb terminals or other apps consuming the output. Colors are better (both Chrome and Firefox format non-strings with color in console) but I can guarantee that if we start coloring or quoting console output, there will be a huge outcry because console is the go-to method of writing to stdout for many users. If you want to limit your changes just to util.inspect that might be more acceptable.

@silverwind this PR actually broke a couple of expectations from modules like uglify and we did not fix those expectations. With my suggestion, those expectations would likely be met again.
So what I propose might actually "unbreak" the ecosystem and I do not see this huge outcry that you talk about. Adding the quotes would be a very consistent in this case as it's only done in cases with multiple data types and it makes it easier to identify those types immediately.

I used inspect by mistake in the examples. util.inspect only accepts a single input argument and nothing I said above would fit to that.

Yes, there were a few breaking cases in here, but they only applied when first arg was not a string. Now we're talking about changing the first arg too and I could see applications using for example

console.log('Number of open tasks:', num)
// now: Number of open tasks: 5
// then: 'Number of open tasks:' 5

I think this would be quite unexpected to the user, and not straightforward to solve.

Could this conversation be moved to a new issue or PR? I'm going to skip uglify-js in citgm until it's clear if they have to adapt their tests or it's something to fix in core.

lookup: skip uglify-js on v12
Some tests are broken by changes in the output of `console.log`. It's
not clear yet if this should be fixed in Node core or in the module's
tests.

make tests compatible with Node.js 12
In Node.js 12, the formatting of console arguments will change slightly.
Previously, a string other than the first argument was formatted using
single quotes if the first argument was non-string. Now, quotes are
never added regardless of position of a string argument.

To make test compatible in all Node.js versions, I work around by
ensuring the first argument to console.log is a string which prevents
the quotes from being added on older versions of Node.js.

Make tests compatible with Node.js 12 and prerelease versions (#197)
* make version check work with prerelease versions

semver.satisfies does not match a prerelease version against a
non-prerelease one, e.g. 12.0.0-pre does not match >= 10. Use a regex
match to workaround this fact.
