I am trying to figure out how to achieve consistent console output across Node.js versions, in a module that applies colors to the text.
Up until v12 of Node.js there was no problem, but with v12 many of my tests stopped working, and here's why...
const a = [1, 'text\nwith', 'line\nbreaks'];
console.log.apply(null, a);
This test outputs the following under any Node.js version before v12:
1 'text\nwith' 'line\nbreaks'
And after v12, it outputs the following:
1 text
with line
breaks
i.e. it breaks console output on \n.
Is there any new API that can make the output consistent across multiple versions?
Is there a known commit/PR that brought this breaking change?
UPDATE
Probably even a better question - how to detect that the Node.js version supports this new line-break on the console output?
Internally, it seems that Node.js makes the call into util.format:
const util = require('util');
const a = [1, 'text\nwith', 'line\nbreaks'];
console.log(util.format.apply(null, a));
The question is then, how to determine if util.format now supports a different output?
Just escape the backslash character. I don't know what version of 12 "broke" as you say, but use \\n to escape instead of \n.

This question is based on this question. During coding, I got some new things popping up and because the initial question is properly answered, I want to describe my issues in this question.
My goal is to have a RegEx which filters out everything, instead of some special requirements:
Alphanumeric allowed
non-Lating e.g. Chinese or Japanese allowed
.,-?!"'=$|<>[]{} allowed
Works with NodeJS 8.9.4
During implementation of the answer from the main question, I've found out, that this only works with newer Node versions (because of the supported ES version). Sadly, our project runs on 8.9.4 which can't be changed in any way. So upgrading is not an option.
I've started searching around and found this page: https://github.com/slevithan/xregexp/blob/master/tools/output/categories.js
With the help of another question, I've tried to build something together which matches my requirements. I came out with:

Somehow, the answer from the first question works better as the parsed categories from me. So there must be something wrong, which I'm unable to find.
At the end, I want to put everything inside a var.replace() command, to replace everything bad with a single whitespace.
For testing, I'm using: https://regexr.com/
You can either use regexpu to transpile the regex into an ES6-compliant regex, or you may go to the Unicode Utilities: UnicodeSet page and get the code point ranges manually.
In your case, paste [^\p{L}\p{N}] into the Input field, check Abbreviate and Escape, then click Show Set. Add the .,?!"'=$|<>[\]{}- at the end of the character class. Then, double the backslashes (also, escape the ' or ", your string literal delimiter char, I escaped ' below) and put inside the pattern_from_uu variable definition in this JavaScript code and then, all you need to define the regex is const reg = new RegExp(pattern, "gu") or const reg = new RegExp(pattern, "u"):

var date = /(?|(Sat)ur|(Sun))day/;
console.log(date.exec("Sunday"));
This fails with:
SyntaxError: Invalid regular expression: /(?|(Sat)ur|(Sun))day/: Invalid group
Is there a version of NodeJS that supports this? Or some library out there that
I tested this with nodejs v8.12.0
Not really. An advanced alternative regex library for JavaScript is XRegExp, but it doesn't have the feature you're after - not even as an addon.
A simpler regex feature that is supported by XRegExp is named capture groups, so you can write:
var days = XRegExp('(?:(?<d>Sat)ur|(?<d>Sun))day', 'gi');
You can't use numbers as group names, but named groups should fit what your needs - they allow backreferences (using \k<d>), replacement (${d}), capturing (match.d), and all features of a regular numbered group.
Named captured groups is supported natively by ES2018: ES2018 Regular Expression Updates.
According to node.green, named capture groups are supported by Node.js ≥10.3.0, or by ≥8.6.0 with the --harmony flag.
Нello! I'm running a clustered node project with a number of nodes. They do a fair bit of console output. I also want to be able to do beautiful coloured output.
My problem: I'm getting jumbled, race-condition-y console output ONLY WHEN USING COLOURS.
I've been boiling things down to isolate my issue, and my current setup is for every node in the cluster to have its own unique string. This is the only string the node will output to console.
let chars = 'abcdefghijklmnopqrstuvwxyz1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ';
let getMyUniqueString = () => {
return chars[Math.floor(Math.random() * chars.length)].repeat(100);
};
I run a bunch of nodes which are using this function to determine their unique strings, and I see something like the following:
Isn't that beautiful! No matter how long and how furiously all those nodes output, this console output never gets jumbled.
Now, I try with unique strings which contain just a tiny bit of colour:
let chars = 'abcdefghijklmnopqrstuvwxyz1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ';
let getMyUniqueString = () => {
let redEscSeq = '\x1b[41m';
let clearEscSeq = '\x1b[0m';
let aRedBoxOfText = redEscSeq + ' ' + clearEscSeq;
let repeatedChars = chars[Math.floor(Math.random() * chars.length)].repeat(100);
return aRedBoxOfText + repeatedChars;
};
And look how sad some of my results look!
The ONLY way data is being sent to the terminal, across all nodes, is through the console.log function.
Why is console.log smart enough to keep the output from many nodes unjumbled when there is no colour, but not smart enough to do it when even a bit of colour is included??
Thanks for any help!
(Just for reference, the following image is the kind of unjumbled output I'd expect to see consistently in the coloured case; it's just a red box (two spaces with red background colour) prefixing each line:)
EDIT: While this problem exists in the native windows "cmd.exe" console, in the powershell console, and in ConEmu (a nice 3rd party windows terminal shown in the screenshots), it does NOT exist in the Cygwin terminal! In Cygwin there is never any jumbling, even with tons of colours and async output. Is there anything I can do to encourage this Cygwin behaviour in other consoles??
It is a race condition, and it's unlikely you can do anything about it, maybe except reporting a bug to library used by nodejs.
While windows API itself does in fact support printing multi-colored string in a single API call, as shown here: https://learn.microsoft.com/en-us/windows/console/writeconsoleoutput, where every character contains its color information. But it also doesn't support ANSI escape codes. And this is not what's actually used by javascript.
Nodejs engine uses a library called libuv to write strings to terminal, which is crossplatform and internally translates ANSI escape codes to do the right thing. But if you look closely at the source of libuv for handling ANSI escape codes, you will see that it does a complete buffer flush after every escape code, meaning at some poiint it has to become multiple windows API calls to print one line of text.
Under normal circumstances this is obviously not an issue, but if you have multiple threads doing the writing, it means that parts of those lines may become jumbled... just like what you see here.
So the answer here is that there is no solution. Or you accept using cygwin as a solution.
I tried the following snippet of Alloy4, and found myself confused by the behavior of the util/Natural module. The comments explain more in detail what was unexpected. I was hoping someone could explain why this happens.
module weirdNatural
private open util/natural as nat
//Somehow, using number two obtained from incrementing one works as I expect, (ie, there is no
//number greater than it in {0,1,2}. but using number two obtained from the natrual/add function
//seems to work differently. why is that?
let twoViaAdd = nat/add[nat/One, nat/One]
let twoViaInc = nat/inc[nat/One]
pred biggerAdd {
some x: nat/Natural | nat/gt[x, twoViaAdd]
}
pred biggerInc {
some y: nat/Natural | nat/gt[y, twoViaInc]
}
//run biggerAdd for 10 but 3 Natural //does not work well, it does find a number gt2 in {0,1,2}
run biggerInc for 10 but 3 Natural //works as expected, it finds a number gt2 in {0,1,2,3}, but not in {0,1,2}
Thanks for this bug report. You are absolutely right, that is a weird behavior.
Alloy4.2 introduced some changes to how integers are handled; namely, the + and - operators in Alloy4.2 are always interpreted as set union/difference, so built-in functions plus/minus have to be used to express arithmetic addition/subtraction. On the other side, the util/natural module (mistakenly) hasn't been updated to use the latest syntax, which was the root cause of the weird behavior you experienced (specifically, the nat/add function uses the old + operator instead of plus, whereas nat/inc doesn't).
To work around this issue, you can either
open the util/natural module (choose "File -> Open Sample Models" from the main menu)
edit the file and replace the two occurrences of <a> + <b> with plus[<a>, <b>]
save the new file in the same folder with your model als file (e.g., as "my_nat.als")
open it from your main module (e.g., open my_nat as nat)
or
download the latest unofficial version where this bug is fixed (you might need to manually delete the Alloy temp folder to make sure that the Alloy Analyzer is not using the old (cached) version of the util/natural library).
I'm trying to insert a large amount of text into a mongodb collection from nodejs. I've done some testing and found that the maximum length of the string can be only 49072. Here's how i do it:
collection.insert({'largetext':POST["text"]});
Basically if I do a substring of (0, 49072) it works fine. (I can see the collection in mongodb). But if i do (0, 49073) then it just never appears in the db. There is no error either (I tried using {safe:true}, and using an error function to capture any errors...there weren't any).
I'm using http://github.com/christkv/node-mongodb-native/ as my mongo driver.
Anyone have any clues what could be wrong here? I think it might be some Javascript maximum string length restriction, but if it is how do i still insert large text?
Thanks!

passes without any problems so this might be a red herring and the problem could be somewhere else. I would suggest you try the test and see if it passes. also make sure you are on the latest node.js version and latest npm package.
