javascript. i have a stack of variables which are all almost, but not quite, the same. (e.g. whatever_1, whatever 2, etc.) i need to iterate through them. right now i'm just building the variable names as strings and then slapping them into an eval() because idgaf

is there a better/more elegant way to do this?

eh. proper async/await support is a strictly better interface, but promises at least papers over the callback hell, and with yield they can even be tolerable to write

yeah as soon as you have yield or some other ersatz do-notation, you don't even have to the cps transform for the nested stuff

quote:

the big problem with the js promises i've seen is they tend to swallow errors because there's nowhere to raise them

with an async statement you have a call point where you can just raise the exception as normal, with a proper stack trace and everything

well if you don't maintain a callstack you don't get poo poo, but it is surprising, to me at least, that errors get thrown down the chain in javascript rather than up, given it doesn't do any tco

quote:

promise stack traces tend to suck, when you even get them

yeah

when your state machine transitions map to function calls it's always a happy fun time, and hell when it isn't

slap em in an object mate

var my_butt = {};

my_butt.whatever_1 = "poop fart";

then you can sorta iterate through em

for (var c in my_butt) { console.log(c, my_butt[c]) }

once i realised that the code that was the most aesthetically pleasing was also the most unfriendly to beginners or new people to a code base, often hard to find somewhere to start, or relying on a very very clever and well greased abstraction

i've become a lot more sloppy where i know there isn't really a corner to cut but just a bikeshed to paint

best thing to do is read a bunch of other libraries for a bit and pick up bits and pieces rather than trying to pick everything up at once

unless you've done enough of a similar language where it's easier to learn the differences and core operations

i'm familiar enough with basic concepts and have glancing experience with c++ and java. hobbyist-grade knowledge, i guess?

educationally i got through about � of a computer science degree before switching to literature/writing, so y'know.

Proper support for yield/poll/wait/fetch whatever beats the hell out of promises day and night. I guess cps promises are an okay lesser evil when you don't have that though.

if it's anything like our 350 line SSRS sprocs it will create a table, then insert some stuff into it, then potentially modify those rows with sums or differences or hiding negative values or whatever, then return that table to the SSRS report

comment out the sproc parts and run it as a SSMS query

then comment out everything except for the initial table generation

slowly uncomment sections in turn (hopefully they should be linear/procedural, ours are) until you work out what each piece does

good luck

(it really sucks that a report can't be backed by a nice snippet of C# code without doing annoying things like SQL Server hosted assemblies)

yeah it makes sense (other than the confusing as hell short names for all the tables) and i'm reasonably competent with sql server but i've never worked with anything so big, so complicated, or so on a client's production system before and it's scary af

nothing against coworkers but apparently this is true from what I observed.

plus I already got the "you did what to the client's data" out of the way

protip: don't delete things from client production databases without telling someone in charge first (double happy ending: they had a daily backup plus the one I made beforehand and I was right anyway)

actually, doing anything at all in production other than "roll out a new version" is highly suspicious. clone that stuff to a dev instance (if necessary) and work on it there.

I agree with all these things because working with production databases for a huge app I know not very much about the inner workings of is :froggonk:

we have local instances and test instances out the rear end but it's always the loving case where they tried to import data from Lotus 1-2-3 using Windows CardFile or some poo poo and their data got hosed

impostor syndrome is failure to recognize that the only job skill that really matters over anybody's career is if you can spit game or not, and if you can learn poo poo to back up that game

code:

import java.util.Scanner;

public class CLI {
	
		public CLI(){
		}
		
		public static void main(String args[]){
			boolean running = true;
			        Scanner s = new Scanner(System.in);
			        while(running){
			           String command = s.next();
			           System.out.println(command);
			        }
		}
}

so say I have something like this. i export it as a runnable jar (with eclipse), and then get a jar file that wont run. ive tried using command line and running:

java -jar testJar.jar

but nothing, the process just hangs. no errors, just nothing
