00:45:16Varriount_federico3: I don't think so. You can set a global flag thought.
00:46:14Varriount_federico3: The problem with raising an exception on SIGTERM is that A: How would you catch it in a deterministic way, and B: You would violate the expectations of code that is guaranteed not to raise any exceptions.

04:57:29girvoHey all
04:58:18girvoI'm working on a Docker Client for Nim at the moment for some tooling we're building at work
04:58:44girvoIt's going quite nicely when using HTTP as the transport, which is fine, but typically one uses a unix socket to communicate to the Docker daemon
04:59:20girvoI can see the low-level posix API in nim can handle unix sockets, but is there anything higher level? Using httpclient is beautiful, but doesn't work with a unix socket at the moment it seems
05:09:36ldleworkgirvo: don't know the answer, but awesome to hear

08:39:19veganskawayHi to all! Anyone knows this guy? https://github.com/wheineman. His REPL for Nim (nrpl) project is cool, but it's frozen and bugs are not fixed for a long time.
08:42:31veganskawayI sent him e-mail about a month ago about it, still no answer. Maybe we can change it's repository url in nimble packages to it's working fork?

14:43:21enthus1astim learning pegs atm and i'm stuck at a strange issue, i would like to match an email header but the match is stopping to early and i don't know why.

15:25:17cheatfateenthus1ast, do you make finds() on full message? or you doing your finds() while downloading?
15:26:35arnetheduckhi, anyone knows why in the newSeq impl, addInt & mulInt are called as functions (vs using just +, * as usual)?
15:26:36enthus1asti read the file with readFile
15:28:10enthus1astcheatfate: i have some email test files, and i read one of the examples. My idea was to match everything that is not a double newline to get the header.
15:31:41cheatfateif assume that peg module - not buggy, then it looks like your algorithm fail
15:32:13cheatfateenthus1ast, i dont know may be you are reading file by 16 byte chunks or something...
15:32:31enthus1asthttps://gist.github.com/enthus1ast/f65590bd1dc0c3c8db29e569922c79f4
15:32:31enthus1astthis is the whole example
15:32:38enthus1astmhh
15:34:08dom96enthus1ast: You just want to capture the headers?
15:34:36enthus1astyeah.
15:36:49Araqarnetheduck: because these must always perform overflow checks due to security issues
15:37:22dom96enthus1ast: Just write a little while loop to capture the characters until you find two `\n`'s
15:37:40enthus1asti've done this this works but i will learn pegs : )
15:40:15arnetheduckoh, so they bypass the mAddInt magics on purpose? ie isn't there a pragma that could be used?
15:41:44cheatfateenthus1ast, its not a good idea to parse emails with pegs :)
15:42:06enthus1astbut the idea should be correct right? i match everything that is not a double newline, as the seperator i choose the double newline
15:42:19enthus1astcheatfate: why? ;)
15:42:26arnetheduckoh, and incidentally the gogc newSeq uses +,*, so that would be a bug?
15:43:13Araqarnetheduck: yup.
15:43:46cheatfateenthus1ast, security issues can be happen... for example somebody can send you endless From: ....
15:43:51Araqthere is a .push overflowChecks:on but that would turn it on for the whole proc
15:45:05cheatfateenthus1ast, this is main problem of current asynchttpserver.nim
15:45:42enthus1astmhh too bad
15:47:30enthus1astwith endless From you mean a long line without a newline?
15:48:10enthus1astcheatfate: ^
15:48:19cheatfateyep
15:51:18cheatfateyou must also check this http://stackoverflow.com/a/1592310/3208443 and you will get some info about 'folding' :)
15:51:31cheatfatethat can be happend in emails
15:52:30enthus1astjep
15:53:04enthus1astive addressed this with a simple "return header.replace(peg"\n\s","")"
15:53:20enthus1astthis is what the rfc says
15:54:07enthus1astthis is what i would do to the header if i could extract the header : )
15:55:36enthus1astthen i would loop through the splittet("\n") header then i use pegs to match key: val etc.
15:56:12enthus1astso i could check the line lenght first before feeding it to pegs
15:57:02cheatfateenthus1ast, it looks like you use cannon where you can use only knife :)

18:12:46dyce_or like 32KB of ram?

18:59:51dyce_ldlework: why is that
19:00:55ldleworkwell nim is a fairly complicated language
19:01:07ldleworkits certainly not characterized by its simplicity
19:01:28ldleworkits not a dig on Nim, I love nim obviously, but just being straight about it
19:01:53dyce_ldlework: would you say python keeps it simple?
19:02:41ldleworkSort of? Not really? Python has a good deal of syntax too. However it makes up with it by having a consistent data model.
19:03:23ldleworkJust because you can use a subset of a thing effectively doesn't objectively change what it is qualitatively.
19:03:51ldleworkgo and lisp are simple languages, Python and Nim are rich but each to use languages
19:03:56ldleworkthere's a difference imo is all
19:04:05ldleworkeasy to use*
19:04:44dyce_i think python is pretty simple. but im open to seeing a language. I don't like how go looks, thats my python bias
19:05:31ldleworkbut you're not talking about the complexity of the language
19:05:41ldleworkwhether you like something has no bearing on this topic :)
19:05:47ldleworkbut I do agree, python and nim are my favorites

21:07:26dyce_arduino ram is 32KB
21:09:26Matthias247that makes a raspberry pi have lots of memory ;)
21:11:19dyce_i guess i need to read this: https://www.quora.com/How-did-game-developers-pack-entire-games-into-so-little-memory-twenty-five-years-ago/answer/Dave-Baggett?srid=z9ZA&share=1
21:11:25Matthias247didn't know what the current states of routers is, but most "application cpus" (Cortex A, ...) will nowadays have quite a bit more. Because you don't get so small RAM chips anymore
21:11:36dyce_had no idea playstation 1 only had 2MB of ram
21:13:01dyce_Matthias247: ideally, raspberry pi foundation should improve their distribution model for pi zero.
21:13:17dyce_hopefully pi zero 2 will do that
21:13:18Matthias247the microcontrollers we use in some automotive products have 2MB RAM and Flash. You can get quite a lot of logic in there
21:13:27dyce_maybe it will be called pi -1
21:13:47Matthias247I thought the zero was totally uninteresting, because it lacks network
21:13:59dyce_im hoping pi zero 2 will have BLE/Wifi
21:14:07dyce_that would be fun
21:14:37dyce_if you live by a microcenter you can actually get one for 5 dollars
21:15:07dyce_dont know when shipping things that could fit in an envelope costed more than a few stamps
21:17:42Matthias247I have bought a pi2 wenn it came out and haven't even unpackaged it
21:17:49Matthias247probably I don't need one more :)
21:21:09dyce_this one is cool too https://wiki.hackerspace.pl/projects:zsun-wifi-card-reader
21:21:15dyce_can get for 8-10 dollars
21:22:23Matthias247yeah - in the meantime there's quite a lot of interesting hardware for cheap prices
