This type of message should be a code block reply. ^

yeah...

or like, use triple backtick like most sane things (i can see reasons against that tho but still)

Chat – SE's forgotten child.

edit a third time

⎕←42

mod abuse

hm. i'll need to store which replies are attached to which messages

which shouldn't be an issue since i only need to store them for like 2 minutes anyway

Too bad TA didn't take off. It has really nice chat features, including code fences with syntax colouring, native real-time TIO integration (it has preview of your message, and recomputes via TIO while you're writing). Even after you post a TIO-powered message, others can "edit" (locally) your input and the output is updated (only for them).

@Adám if a message gets edited and the bot can no longer edit its reply, should it just post a new one or just ignore the edit?

this can only happen if a mod does the editing tho

@Adám oh wow that's really cool

TA looks like it has a lot of features but its design is kind of poor (no offense to it - it just looks underdeveloped) and unfortunately never really got the community built up :(

It also comes with native customisable language bar, and lets you choose from a selection of fonts.

@hyper-neutrino Yes, sad.

@hyper-neutrino I wouldn't worry about it then. But couldn't it happen if someone edits just before the time limit?

oh, true

i guess i'll just watch edits and if there's an attached message, it'll attempt to update it, and if failed, just ignore it, and if not, add a new reply

Sounds sane enough.

If failed, it could respond with "Too late to edit my reply." Not critical though.

i mean, at that point i may as well just send the new reply :p

@Adám see

Woo.

editing to something with no output will not do anything though

boo

@Adám Response looks like a 1-by-0 matrix.

or rather, something that doesn't contain code

It could delete its message ;-)

like editing `⎕←42` to hello will leave the 42 response, but editing it to `⎕←0⍴0` will still edit the reply to the "looks empty" thing

But then it can't undelete it…

⎕←0⍴0

@hyper-neutrino Response looks like a 1-by-0 matrix.

@hyper-neutrino 42

@Adám yeah, that's the problem with it... idk. i could also just edit down the reply so there's still a hooked message to edit instead of needing to repost

"Nothing to see here."

@hyper-neutrino How hard would it be for the bot to detect messages that begin with "⎕←" or "⋄" and respond "Did you forget to put backticks around your code?"?

@Adám not very. should it just run it anyway or just reply with that?

also i could make it so replying "no" to that message makes it never say that to you again :p

@hyper-neutrino I'm not sure that's a good idea, but if you reply "yes", it could reply with the result :-D

But seriously, no, I don't think its a good thing for it to run unbackticked code.

oh wait, if you don't backtick it i can't scan where it ends

The reason is that things can get rather confusing ⎕←*\1 2 3

Did you forget to add backticks around your code (`code`)? You can edit your message and I will edit my reply.

oops forgot to make it ping

@neutrino-bot Very nice. I was just about to suggest the note about editing.

How comes the bot doesn't get rate limited on edits?

i think it does

but i get rate limited too so i can't edit quickly enough to make it hit the limit :P

Ah.

alright, changes applied to the real bot
