IIRC a List<T> is internally an array; a Dictionary<T> is internally a HashSet<T> ..right?

yeah

wait, no

<facepalm/>

hey I had 4 hours of sleep in the past 48 hours

gimme a break

mjolka

@Mat'sMug goto sleep;

Mat's Mug

I can't, Bar doesn't resolve

mjolka

you can hit the Bar later

i think i've gone down a rabbit hole where my servicelocator needs a servicelocator of its own. something is seriously broken with this design

Mat's Mug

but... ....why service-locator?

mjolka

because i don't know any better, probably :(

it would be great if i could pick your brain about this problem, some other time

Mat's Mug

5:10 AM

sure!

mjolka

thanks :)

Mat's Mug

ah, found it

    private readonly Stack<Declaration> _withQualifiers = new Stack<Declaration>();

^^ I have Class1 declaration right here.. and I'm not using it

mjolka

@Mat'sMug i think if you turn on Warnings as Errors, unused fields will cause the build to fail

Mat's Mug

well I Push and I Pop it, so it is used.

mjolka

ah ok

                var parentMemberName = memberProcedureCallContext.Stop.Text;
                var matchingParents = _declarations.Items.Where(d => d.IdentifierName == parentMemberName);

                Declaration parentType = null;
                if (_withQualifiers.Any())
                {
                    parentType = _withQualifiers.Peek();
                }
                else
                {
                    parentType = matches.SingleOrDefault(m => matchingParents.Any(p => m.ComponentName == p.AsTypeName));

wtf

I wasn't Peeking at it though ;)

mjolka

see that's a good place to use a ternary

Mat's Mug

lol.. was going to say (resists urge to turn if-else into ternary)

but yeah

var parentType = _withQualifiers.Any()
    ? _withQualifiers.Peek()
    : matches.SingleOrDefault(m => matchingParents.Any(p => m.ComponentName == p.AsTypeName));

mjolka

is matchingParents used elsewhere?

Mat's Mug

oops, I borked it

@mjolka nope

            var memberProcedureCallContext = context.Parent as VBAParser.ICS_B_MemberProcedureCallContext;
            if (memberProcedureCallContext != null)
            {
                var parentMemberName = memberProcedureCallContext.Stop.Text;
                var matchingParents = _declarations.Items.Where(d => d.IdentifierName == parentMemberName);

                var parentType = _withQualifiers.Any()
                    ? _withQualifiers.Peek()
                    : matches.SingleOrDefault(m => matchingParents.Any(p => m.ComponentName == p.AsTypeName));

well I'm missing d.DeclarationType == DeclarationType.Class there for sure

@Mat'sMug this Controls that you mentions seems to be a WinForm thing. do you happen to know the wpf equivalent of it mat?

Mat's Mug

5:26 AM

@Mehrad indeed. You don't need any of that in WPF. Just use databindings to your ViewModel

Mehrad

this is a shitty little project and I wanted to do the easiest possible

Mat's Mug

yes, easy in WPF means databindings and viewmodels.

otherwise you get into very complicated shitz

Mehrad

:"(

Mat's Mug

make a class that implements INotifyPropertyChanged and raise the PropertyChanged event whenever a property setter is called

have a public bool property bound to each checkbox and you're done

Mehrad

:"""""""""""""(

Mat's Mug

5:29 AM

you're thinking in WinForms

life in WPF gets very complicated very fast if you think in WinForms

Mehrad

Friday afternoon + shitty little project = laziness :)

mjolka

@Mat'sMug looks like multiple enumerations of matchingParents -- might want to consider something like this

    var parentMemberName = memberProcedureCallContext.Stop.Text;
    var matchingParents = _declarations.Items
        .Where(d => d.IdentifierName == parentMemberName)
        .Select(p => p.AsTypeName)
        .ToHashSet();

    var parentType = _withQualifiers.Any()
        ? _withQualifiers.Peek()
        : matches.SingleOrDefault(m => matchingParents.Contains(m.ComponentName));

Mehrad

I have never Winformed so I wouldn't know

@Mat'sMug thanks

mjolka

(i made up ToHashSet. why isn't that a thing?)

Mat's Mug

@Mehrad whenever you think you need to deal with controls anywhere other than in the view's code-behind (i.e. almost never), you're thinking in WinForms ;)

if you really want to write your logic in the view's code-behind, you can. but that's not something WPF makes easy. you're going to end up with named controls, and very WinFormsy code.

Q: Highly repeditive code when using multiple dispatch to walk tree

Because (in Julia 0.3 at least) every tuple has its type encoded, a tuple containing either further tuples or leaf node types, is a reasonable way to represent a tree. Then walking the tree can be done with multiple dispatch of methods. However this does seem the result in a lot of replicated co...

Mat's Mug

@mjolka ooh good catch! R# seems to skip those in anonymous methods...

(déjà-vu)

mjolka

all over again

Mat's Mug

ah, the bug is that I'm matching parentMemberName, which is Foo - but since I'm in a With block it's the type of Foo I need to match.

back to if-else ;)

wait, no.. that's what Peek does - gets me Class1

mjolka

@Mat'sMug what do you think of ToHashSet?

Mat's Mug

I think there's gotta be a reason why it's not implemented ;)

A: How to convert linq results to HashSet or HashedSet

I don't think there's anything built in which does this... but it's really easy to write an extension method: public static class Extensions { public static HashSet<T> ToHashSet<T>(this IEnumerable<T> source) { return new HashSet<T>(source); } } Note that you really do want...

Mat's Mug

ah

oh wow.. I have 4 matches for Foo: 3 procedures and 1 variable. Only one of them is in the _currentScope. I guess I've found my bug :)

return parentType == null ? null : matches.SingleOrDefault(m => m.ParentScope == parentType.ParentScope);

return parentType == null ? null : matches.SingleOrDefault(m => m.ParentScope == _currentScope);

...wait.. then why do I need the parentType for?

ugh

Mehrad

@Mat'sMug I agree. as I am familiar with wpf i have started this project in it but I should've done it in Winforms. It's okay. I am almost done. it was a single day job :)

6:11 AM

the @Mug here at this hour? seems unusual

mjolka

he's having parent issues

janos

lol, I can see that

Mat's Mug

oooooh the stupid bug

scoping issues actually

return parentType == null ? null : matches.SingleOrDefault(m => m.ParentScope == parentType.Scope);

parentType.Scope, not parentType.ParentScope

that works beautifully!

ta-da!

refactor/rename works!

thanks @mjolka!

mjolka

@Mat'sMug not sure what i did but you're welcome!

Mat's Mug

been my rubberduck ;)

2:17AM, TTGTB

mjolka

6:17 AM

it's rubberducks all the way down

Mat's Mug

no. TTCTC!!

mjolka

time to check in the code?

off for a smoke, night mug

Mat's Mug

commit these changes

oh I have other tests to do... gotta see if functions work, property get/let/set too

and then member calls as well

janos

"checkin the code" also works :)

Mat's Mug

OMG IT WORKS!

Q: My first complete haskell program -- A websocket channel server, intended for webRTC signalling

I've written a server to use as a webRTC signalling channel. It's totally generic though, any websocket client can use it. I feel like the first half of the code (non-IO) is decent, but the second half (IO) is pretty bad, with long functions and very dense code. Here is the code, including an exa...
