16:37 <EEVV> hello

16:37 <EEVV> I'm trying to compile pony on my raspberry pi and I get `execinfo.h: No such file or directory`

16:41 <jemc> have you already looked into which package provides that for your distro? (rapsbian?) probably called `libexecinfo-dev` or some such

16:44 <EEVV> jemc, someone should add that to the readme.md

16:44 <EEVV> unless there is a better place to figure this stuff out...

16:47 <jemc> if you want to add a Raspbian section to the README with your findings (similar to the other Linux sections), that would probably be fine

16:47 <jemc> the Alpine and OpenBSD sections both mention needing to install libexecinfo - I'm guessing the other linux distros don't because it's included by default or something

17:15 <EEVV> what is netatalk/at.h?

17:18 <jemc> I'm not familiar with it, tbh

17:20 <jemc> what's the context?

17:21 <slfritchie> AppleTalk network protocol

17:22 <EEVV> apparently it is part of glibc-devel

17:22 <EEVV> but I'm on musl, sadly I don't think a package for that library exists

17:24 <slfritchie> There's an ifndef for alpine linux in socket.c that you can twiddle/move to to account for it. Or just delete the #include line. I was trying to be inclusive of many network protocols that many OSes support ... but keeping track of all the Linux distros is impossible.

17:25 <EEVV> well I'll ask around if there is a package for this

17:28 <EEVV> what is libponyrt?

17:28 <EEVV> do I need that

17:30 <jemc> libponyrt should be built as part of running `make`

17:38 <EEVV> can I somehow have a behaviour in my TCPConnectionNotify so I can send data?

17:38 <EEVV> to the client

17:42 <jemc> no you can't, but there are workarounds; if you could have such a behaviour, what would the parameter(s) be?

17:42 <jemc> (I'm asking the question because the answer will tell me how to advise you to workaround)

17:43 <EEVV> jemc, an array of bytes

17:43 <EEVV> well let's this is what I want do do

17:43 <EEVV> my TCPListenerNotify would have a loop running that every... let's say 30 seconds it tells all of the connections to send a ping

17:49 <jemc> if what you want to send is an array of bytes that needs to be encoded by the listener into the protocol format, then you're in luck

17:51 <jemc> you can implement `sent` and/or `sentv` in your `TCPConnectionNotify` to interecept the data that is being written to the socket actor and modify it as necessary before it actually gets written: https://github.com/ponylang/ponyc/blob/8276504b32bc6f8cf627ae0e37c65b23296d4efc/packages/net/tcp_connection_notify.pony#L51-L66

17:51 <jemc> basically, you can use it as a hook to encode your protocol specifics there

17:51 <jemc> for example, the stdlib SSL library uses it in this way: https://github.com/ponylang/ponyc/blob/8276504b32bc6f8cf627ae0e37c65b23296d4efc/packages/net/ssl/ssl_connection.pony#L46

22:16 <harber> i'm just starting to goof around with pony. i can use lldb via cli, but has anybody figured out if there's a combination of things that works for debugging via vs code lldb extensions?

22:22 <jemc> I've only ever invoked via CLI, so I can't help with vscode setup, unfortunately

22:23 <jemc> if you don't get a response from anyone here, you can try our new Slack server for possibly a broader reach in your question: https://www.ponylang.io/get-slack-invite
