Introduction
Comma-leading lists are an objectively better presentation style.
They make logical sense; the next value on the list is d...

I read it, I saw maybe a thin benefit. But I just can't do it. It make me want to cry.
I do similar for ternary and logic operators. It has all the benefits of the above, plus you can comment out the line without having to faff about with commenting the '&&' or '||' at the end of the previous line.
My god this actually convinced me
I write SQL this way - in a SQL editor (like SQL Tools) and in my code (mostly Visual Studio). You can comment out individual items from your select and not break anything if you structure it right.
I didn't read the post so if that's what he said then I completely agree :-)
I refuse to do this. Even though I really should
The git argument seems correct but doesn't it just reverse the problem? Wouldn't adding a value to the top of the list have all the same problems?
adding to the top will create a [+2, -1] diff in both styles. you'll need to keep the opening bracket on its own line to avoid that.
So yes?
uh, yes, but 'reverse the problem' is incorrect since it exists for both
But that depends on the style of the language or developers involved. When having the bracket on a separate line is expected, "reverse the problem" seems correct to me.
separating the bracket will fix the problem for both styles.
logically speaking, there’s no ‘reversal’ no matter how you peg it, as you’re coupling the data with its dependent comma instead of separating them
The reversal is in the location of where the style causes potential git merge issues. With comma-first the issue can happen at the top of the list with comma-last the issue can happen at the bottom of the list.
Im not sure what you mean by removing the dependency on the comma. If the language uses commas to separate the data there is no real way to remove that dependency. It is built into the language.
ah, i get you, so in the case where brackets are on their own lines, prepending the list will still cause a double diff
in fairness, i’d argue that appending is much more common from my personal experience, be it adding adding data to a JSON, extending an SQL query or passing more attributes to an HTML tag
good spot, though 🙂
I wonder the probability of encountering such a merge conflict versus the amount of code you will write (and read) in a not-so-human-readable way. The complexity introduced doesn't justify its use case.
This is genius!
In Elm this is the norm ❤️
I hadn't encountered comma first until recently in some old code. Drove me crazy and I couldn't figure out why someone would do that. This explanation makes a lot of sense.
Thought it was a creepy trolls, but it's arguably logic.
Nice one, I'll go into it
I understand why people are looking at leading commas, but they're a hack to get things to work better with VCS. And you know what? That shouldn't impact how you use the language.
Indeed, just resolve the conflict and move on.
No way the code look awful
no way to get this in an eslint/prettier config to apply automatically?
Write a shopping list in this style and give it to someone more ordinary than Haskell programmers... You will be surprised.
It's just disgusting.
