Q: Unwieldy Rails model method

I was asked to make a view which is a mix of HTML & ERB logic available in multiple views. At first this seemed pretty simple. However, some of these views required the output to be plaintext instead of HTML & ERB. The rational behind this was that the strings can be added to, removed and updated...

Q: Efficiently return a ChatColor

I am working on a plugin for a Minecraft server. In it, I have a function that returns a ChatColor depending on what permission level you are. Whenever I need reference the user with proper colors, I always get a color from the below function. /** * ChatColor * * @param Player * @return Cha...

Quill

Console.WriteLine("Found none count: " + (nodes.Count() ?? 0)); // Operator "??" cannot be applied to operands of 'int' and 'int'

Phrancis

huh?

EBrown

00:34

Unfortunately, I don't see that room being of any value with the current way the chat system stands.

Quill

I thought that was how you use the null-coalesce operator

EBrown

@Quill No.

The left side has to be nullable.

Phrancis

@EBrown Can you clarify what you mean by "current way"? Just curious

EBrown

nodes.Count() returns an int, which is not nullable.

@Phrancis The 20 rep requirement, mostly.

Should SE make a way for RO's to specify a specific minimum rep requirement, then it might be viable.

Phrancis

Oh, right, that is a bit of a PITA but I understand why it is there

Quill

00:35

@EBrown ah, I see. thanks

EBrown

@Quill You can do nodes?.Count() ?? 0, though.

At least, in C#6.0.

Phrancis

Ah, null-coalesce, so handy :) (in SQL at least)

Quill

EBrown

The ?. means "execute the right side ONLY if the left side is not null", then the ?? 0 means "if the left side is null, then evaluate as 0."

Quill

lol

EBrown

00:37

What is that "lol" for?

Quill

your face is glaring at me is all, like that "no face" meme.

EBrown

LOL I see it now.

That stern look, "No."

Also, what are you trying to get the count of where it's a method? A List<T>?

Quill

HtmlNodeCollection part of the HtmlAgilityPack nuget

EBrown

Ah, it doesn't have a Length property?

Quill

and no, I don't think so

EBrown

00:40

Ah, well that's a bummer.

Usually something being a method means it has side-effects.

And it does. It looks like HtmlNodeCollection is an IEnumerable.

This is when documentation is absolutely useless.

But I'd star that.

@EBrown whoops

Your chat profile links to your SO profile, FYI

EBrown

@Phrancis That's because I was on SO before CR.

No idea how to change it.

Phrancis

<-- Click your picture, choose User Profile

Then you'll see a link that say Parent User, click [Change]

That's it

Well that was dumb, I clicked yours expecting the link to be there. Lol

Tomas, this is fantastic. TVM. 1Q - with prices I am just publishing a series of prices for each id (a list/set of prices), but for volume I am publishing series of amounts at various prices (a list/set of price/amount pairs). I notice you have removed what I had declared as a generic and made it Event<int> rather than Event<'a>. Was this by design? I was rather hoping to "put in" the different data 'under' the generic hood. — Simon Woods Jun 26 '12 at 8:04

They could say "the connection is probably lost," but it's more fun to do naive time-averaging to give you hope that if you wait around for 1,163 hours, it will finally finish.

@Quill That's a little frightening, yet cool.

Mat's Mug

wouldn't idiomatic JS be document.getElementsByTagName?

SirPython

Yes, but it's only off by a character.

Aren't both C# and JavaScript part of the ES standard?

difference is that the C# links is likely some IEnumerable<Element> while the JS links is some ..duck.
