Writing rad Elixir

Zach Daniel

Watching now

Thomas Coopman new try to check the latency

Thomas Coopman it's not better

pikdum test

pikdum lol

Thomas Coopman but doesn't matter that much

Zach Daniel lame

Thomas Coopman :D

Max Gorin Testing YT chat latency

Saul Ernesto Hi

shahryar tavakkoli hey

pikdum test

Max Gorin it's showing up in about 5 secs

Thomas Coopman foo

Thomas Coopman yes, it's the video chat indeed

Barnabas Jovanovics hey 👋

riotonthebay It's in main

Bernhard Hackl Typo in `:unles`

Sean Powell I'm new!

Bill Boz can't hear it yet

Bryan Bryce barely

Sean Powell I've been watching both you and Louis a couple of time but never chat. I love it though

Thomas Coopman yes it's fin

Sean Powell Also music is so low

Thomas Coopman fine*

Sean Powell Actually music is fine now

Sean Powell must be the delay

Sean Powell What is this editor btw?

POEtatoenjoyer Nah it's great

Bryan Bryce Zed editor

riotonthebay I believe it's from ignoring the meta when updating the AST during renaming

riotonthebay Ah, fair enough; not sure then. Could be in the fancy shit.

riotonthebay What I do in these cases: in IEx, use Sourceror to parse string of an if both with and without the newline

riotonthebay and compare the meta

riotonthebay (btw, I'm @zachallaun, for whatever reason I can't change my display name on YouTube)

riotonthebay Yes, the do was on the next line

riotonthebay line: 2 in the :__block__

riotonthebay (Sorry, there's about a 15 second delay on chat, I think)

riotonthebay Sourceror just uses Elixir algebra though, nothing custom for formatting

riotonthebay Good, that at least makes the fix easier :)

riotonthebay Yes, agreed

riotonthebay Nice, that's handy

POEtatoenjoyer credo would hate this function

riotonthebay This is a totally separate conversation, but I was thinking that you sometimes want the {:ok, zipper} | :error API and sometimes just always want zipper, and it would be nice to have a naming idiom

riotonthebay Yeah, I think you're right, that returns the zipper if it's {:ok, zipper} and just returns original if it's :error

riotonthebay I missed some context but agreed about path, it's tricky to grok and can be surprising in some cases

riotonthebay Is there a reason we need to be operating on supertrees directly? Can you bust out of the supertree and then re-create them after everything's updated as you want?

riotonthebay Don't worry too much about it, I'm very likely just missing something

riotonthebay I think the piece of context that I'm missing is why the supertree would ever need to be explicitly updated. Wouldn't it reform with new children once you break out of it?

riotonthebay It's definitely hard to describe and talk about

riotonthebay I might be accidentally inventing Sourceror APIs

riotonthebay Okay, I think I finally understand the use-case. The zipper is focused on the OLD filter syntax, and it's inside a within, and you're replacing the single call with a block containing 2 calls.

riotonthebay And you don't want nested blocks

riotonthebay And is reducing over the reversed children of the block and calling Zipper.insert_right not an option?

riotonthebay Fair, you've tried a lot more options than I have

riotonthebay Nah, I know what you're saying though

riotonthebay Stick a backslash at the end of the expectation you're interpolating

riotonthebay Yeah that's a nicer fix

riotonthebay *Shakes fist at YouTube*

riotonthebay Arity?

riotonthebay Good catch

riotonthebay I think there might be some missed first arguments elsewhere

riotonthebay I could be wrong, I just noticed it while you were looking through cases and might have seen it incorrectly

riotonthebay All of this really makes me wonder whether higher-level, "syntax pattern matching utilities" that normalize a lot of this stuff would be possible

riotonthebay because this shit is *really* hard to get right

riotonthebay I agree, somewhere you need this stuff

riotonthebay I wonder though if there are patterns that could be extracted and useful

riotonthebay Yes, exactly that

riotonthebay Regex for source code lol

riotonthebay Cool, I think those two you just found were what I saw

riotonthebay they were one-liners like that

riotonthebay I have to run, but enjoyed this! Will try to tune into the next one.
