 @malte:maltee.de | is there an easy way to use use a negative sign in connections of the connect function of RobustAndOptimalControl? | 19:29:37 |

| @malte:maltee.de | Is this room still alive or is this the widow of a libera.chat bridged room with all the action happening on the IRC side? | 08:52:15 |
 rollskatflat | People still use IRC a lot? | 09:51:26 |
| @malte:maltee.de | ¯\_(ツ)_/¯ | 09:52:46 |
| @malte:maltee.de | I noticed julialang.org mentions zulip, slack and discord, so this room is unofficial? | 09:53:22 |
| 27 Dec 2023 |
 vchuravy | it's not yet active enough to be official | 14:22:32 |
| @malte:maltee.de | Has anyone ever suggested to bridge the different channels? I know slack and discord can be bridged to matrix. Having multiple channels on multiple platforms seems quite inefficient. | 14:55:05 |

 Hannes | I know the Julia Slack can be strict about not archiving the messages on there in any way because they like the ephemeral disappearing messages, so they'd probably be against a bridge | 01:46:30 |
 dionisos | Hi, I am trying to pass a type as an argument of a function, which create other function, using this type (to avoid type instability). But I get this error:
ERROR: LoadError: syntax: local variable NodeType cannot be used in closure declaration

| dionisos | In fact it is obvious it doesn’t work, given that MyType is given at runtime. But I suppose there is some other ways to avoid type instability in these kinds of cases. | 18:07:23 |

 qwjyh | If the type need only one function, then you can use
function (v::MyType)(a::MyType, b::MyType)
...
end
https://github.com/FluxML/Flux.jl/blob/df468ba0a10d86b660eebed98d1b484cbce113a7/src/layers/basic.jl#L170
If the type need two or more functions, define a new method with the type on the first argument. e.g. https://github.com/JuliaStats/Distributions.jl/blob/b2d765246e0f35473fe354dc578a3f7edf11958d/src/univariate/continuous/uniform.jl#L74

Thank you for your answer | 23:29:20 |
| dionisos | I admit I doesn’t know the syntax you are using, I will try to understand how it works | 23:30:01 |
| dionisos | I mean the "(v::MyType)" | 23:30:14 |
| dionisos |
ERROR: LoadError: syntax: Global method definition around test.jl:2 needs to be placed at the top level, or use "eval".
| 23:57:18 |
| dionisos | When I try like that :
function create_function(MyType)
function (test::MyType)(a::MyType, b::MyType)
return a+b
end
return test
end
| 23:58:20 |
| 29 Dec 2023 |
| dionisos | Ok I found how to do that, it should be :
function create_function(MyType, value)
function test(a::MyType, b::MyType) where MyType
return a+b
end
return test
end
But I admit I don’t really understand why.
| 00:04:23 |
| dionisos | Also I am curious about the "(test::MyType)" syntax | 00:05:41 |
| qwjyh | Do you want to generate a function based on a type automatically? If normal multiple dispatch doesn't meet your need, you should use macro. | 00:06:12 |
| dionisos | * Ok I found how to do that, it should be :
function create_function(MyType)
function test(a::MyType, b::MyType) where MyType
