is it possible to define a method dispatching on an object that is a child of multiple classes; for example with made-up syntax: `(defmethod method ((obj (and parent1 parent2))) ...)`

to avoid x-y, i'm abusing classes and multiple inheritance to define traits: https://en.wikipedia.org/wiki/Trait_(computer_programming) and i want to define a method that'd dispatch on any class that inherits from two of the traits

You could use non standard method combinations that walk through the class hierarchy
<_death>
there's no built-in way.. you can introduce an intermediate class and inherit from that, or perform the dispatch yourself, even introduce a new kind of specializer (see project called "specializable")
<nytpu>
i don't want to define an intermediatry class and dispatch off of that, because then a subclass would have to use that intermediary specifically instead of being able to inherit those two traits separately, maybe at different points in the hierarchy
<nytpu>
i'm thinking for the level of complexity it's currently at it'd be best to just use duck typing instead of proper method dispatch; maybe i'd look into a MOP solution if it got a lot more complex

there are also some ambiguities.. for example what if there are two methods, (and p1 p2) and (and p1 p3) and the class is a subclass of (p1 p2 p3)

<_death>
you would have to decide how to resolve them in a way that easy to understand.. CLOS has a precedence rule, but it probably needs to be extended to handle these cases
<nytpu>
_death: yeah, that's true. a lot of ambiguities there

There are ways to dig at languages that don't involve calling people young or inexperienced.

I have tried to figure out what they are afraid of, by interviewing students I had in the past, but their answers are always puzzling.

could it be that you were slightly biased (in favor of your favorite language) when you were interpreting the answers?

When in line at university I tie a paren to a rope, rope to a stick, and use it to scare off the people in front of me in the line.

Try attaching three parens to the rope. Mass panic will ensue.

haskell has balanced parens though, doesn't it

I'm sure it does. I was just joking at the seemingly only existence for this infix precedence operator is to avoid parens and make it confusing to even mathematicians to look at.

Does anyone know if there was a lot of tension between the haskell and CL parties during the standardization period, when haskell showed up on the map? I remember about 20 years ago I was banned from some haskell channel for asking the question about this operator trying not to look like that other research language being standardized?
<mfiano>
That is the reason why I started learning Lisp. haskellers were meanies :(

yitzi: with shasht how can I dynamically append keys to a json object? I have a hash table and I want to serialize that as part of an object, not as separate object
eddof13 has joined #commonlisp

You'd probably have to write your own write-json method...
<Josh_2>
I have (shasht:with-json-object stream (shasht:print-json-key-value ...) ;;my hash (maphash (lambda (key val) (shasht:print-json-key-value ..))) .. next hash ..) but I get no output from the hash tables

Is this a one-off or a specific class with a slot that contains a hash table?

a class
<yitzi>
Do you have some code somewhere... or a paste I can look at? I think I understand what you mean...just want to be sure.
<yitzi>
hmmm...that seems like that should work. Let me see if I can reproduce it.
<Josh_2>
Wait
<Josh_2>
dont
<Josh_2>
Just hold on before you take some time out
<yitzi>
ok
<Josh_2>
Okay it does work I'm just an idiot
<Josh_2>
Sorry :facepalm:
<yitzi>
No worries, buddy.
<yitzi>
If you are doing this a lot you could write a general print method that automatically does this for hash table slots.
<Josh_2>
hmm
<Josh_2>
I am currently only doing it for this one class
<yitzi>
If you look in write.lisp there is a print-json-mop function that you could tweak. Just an idea.
<Josh_2>
There is a lot of variable information for that class so I decided I'd store it as JSON in postgres rather than tweak my db everytime I come up with a new key
<yitzi>
Ok, then maybe not useful.
<yitzi>
ahhh
<Josh_2>
Each slot is a column and the hash tables are jsonb, but when the end user receives a serialized version of the class I wanted the key/vals from those 3 hash tables appended rather than as slot name -> object pairs
<yitzi>
gotcha
<Josh_2>
I want both the request and response to be transparent to the end user
<Josh_2>
let my program sort the keys etc
<Josh_2>
seems to be working, works better than my previous system anywho
<yitzi>
Well that is good.

When telling another service about the current configured timezone in my system, whats the best way? Should I just use the offset relative to UTC? Along with the location used?
<Josh_2>
Ie -6:00 America/Winnipeg or something
<Josh_2>
I dont see a convenient way to do this with local-time
<pjb>
It's better to use a symbolic timezone, because of summer-time/winter-time offsets.
<Josh_2>
Okay :sunglasses:

I have set to America/Winnipeg which has a bunch of subzones but no single zone oof
