00:12:52FromGitter<ephja> yes, the pointer to the element would probably point to something else upon reallocation of the sequence buffer
00:18:09FromGitter<adamrezich> well shoot, should've known that would be too easy. guess I'll have to change my refs to ptrs and make my own allocation system :p
00:23:20FromGitter<ephja> are you implying that the items are references? if so, then you don't need a reference to it since it already is a reference
00:27:10FromGitter<ephja> you can have pointers to the elements as long as you only manipulate the size beforehand
00:27:33FromGitter<ephja> but you might as well store element indices in that case

02:25:50thomasrossIs it possible to make thread variable objects?
02:26:51relaxI kind of hate that so much more of my API is marked "public" so the unit tests can poke a little more. I take it this is just a fact of life?

06:29:47FromGitter<Varriount> @Grabli66 I have an old module that uses ReadDirectoryChanges, you might look at that.
06:30:37FromGitter<Grabli66> Yes, i want. Please, give me link to that module
06:31:20FromGitter<Varriount> relax: use a "when defined(unittest)" to present a set of point declarations, otherwise present private versions.
06:33:34Araqvarriount, relax: the unit test can also 'include' the module instead of 'import' it
06:33:48Araqmuch simpler, no 'when's required

07:00:43FromGitter<zacharycarter> not sure if that answers your question or not
07:00:46FromGitter<zacharycarter> but hopefully it does
07:02:11FromGitter<Grabli66> It's strange. In playground it works. But on local machine i got "type mismatch: got (ref PDWORD) but expected 'PDWORD =ptr DWORD'

07:11:18FromGitter<zacharycarter> you can also add the {.experimental.} pragma to your code and get auto dereferencing - at least I think that's still a thing
07:14:28FromGitter<Grabli66> It's dereferencing. ⏎ But i want pass argument as pointer. For example: ⏎ var mywar : DWORD = 0 ⏎ someProc(ptr myvar) # it's not work [https://gitter.im/nim-lang/Nim?at=59a908d4ba0f0f6e3805dd3f]

Generic my cause a problem as they contain idents which counted as "uses" but I'm not sure.
07:20:49Araqbigepsilon: the problem is that currently 'type' sections are not merged
07:21:02Araqalternatively you can make the compiler frontend process

08:24:12cremGut, dann wenn ich eine Frage über Nim haben werde, werde ich in Deutsch fragen. Ich hatte derselbe in #c++ versucht, aber es ist schwierig zu wählen, ob ich muss ein Englisches oder Deutsches Wort nutzen, z.B. pointer vs Zeiger.

10:43:33Yardanicoah
10:43:59*ShalokShalom_ is now known as ShalokShalom
10:44:14couven92that's why I though timeouts first... the main repo is pretty big, so it might be that nimsuggest has to chew some extra ms to get an answer
10:44:14Yardanicowell it works for me
10:44:37Yardanicowell nimsuggest works for me on unicode.nim
10:44:46Yardanicobut I haven't opened it as a project folder
10:44:49Yardanicojust as separate file
10:45:22Yardanicohmm it works for me even if I open "Nim" folder
10:45:29Yardanicoand open lib/pure/unicode.nim here
10:45:37Yardanicooh yes
10:45:41Yardaniconimsuggest is crashing :)

10:46:40Yardanicoit's not crashing anymore
10:46:41Yardanicohmm
10:47:04Yardanicocouven92, can you try to open some empty folder and open "unicode.nim" as a separate file?
10:47:07Yardanicothis might help
10:50:38couven92found a crash
10:54:10couven92https://github.com/pragmagic/vscode-nim/issues/59
10:54:21couven92It was a timeout issue! :)
10:54:31couven92rejected promise not handled within 1 second
11:09:56Yardanicocouven92, well nimsuggest can crash too :(
11:10:05Yardanicoand there are some memory leaks in it, but no one knows here
11:10:08Yardanico*where
11:11:57couven92that's the thing, I haven't experienced nimsuggest to crash on me
11:12:14Yardanicowell yeah, it's a rare thing
11:12:20Yardanicobut a big thing
11:12:27YardanicoE.g. if it crashes - it can restart
11:12:34Yardanicobut memory leaks - it takes ALL ram on a PC
11:12:38Yardanicoso only reboot :)
11:17:50couven92For example now: Visual Studio Code does not give me any suggestions (nothing in the error log). But when I start nimsuggest with --stdin and command `sug lib/pure/unicode.nim:1521:46` I get `sug skVar lastIndex int C:\Users\fra006\Documents\Source\GitHub\nim-lang-Nim\lib\pure\unicode.nim 1514 4 "" 0 Prefix``
11:18:18couven92so it seems that nimsuggest is doing fine, but VS Code is doing a crappy job!
11:27:12Yardanicocouven92, not vscode itself :)

13:05:06YardanicoI mean you can't make this work
13:05:22Yardanicoyou should firstly declare "b" as a variable

13:08:13Yardanicoalso - there are already Option types in nim stdlib (if you really need something like Boxed)

13:11:56Yardanicobut I'm not sure why appveyor still failed

13:20:06ipjkCould it be that 'var ... = ...' is impossible to overload?
13:20:20Yardanicoipjk, yes
13:20:26Yardanicoit probably could be
13:20:59ipjkI would also recommend keeping overloading of operators at minimum.
13:21:19ipjkCosidering variable assignment is core language syntax
13:22:12couven92AppVeyor still fails: https://ci.appveyor.com/project/dom96/nim/build/229
13:22:18couven92same error

13:23:27FromGitter<zacharycarter> > **<Araq>** oops, I broke boostrapping, working on it, relax
13:23:33ipjkGrabli66: I'd go with Yardanico's example. It's more verbose but tells you exactly what it does. I like to think of operator overloading as uses in edge-cases. Like vectors, etc.
13:23:37Yardanicozach: he fixed it

13:36:51MJCaleyhi, i'm having trouble registering to the forum. i can't get the email since my mail server is rejecting it. it looks like the EHLO it's giving is just "mail" instead of a fully qualified domain name. does anyone know who i could talk to about that? maybe open an issue with the website issue tracker?
13:37:20couven92MJCaley, talk to dom96
13:37:45Yardanicohe'll approve you manually :)
13:38:17dom96|wThe NimForum uses Nim's smtp module to send emails
13:38:43dom96|wThe source code for that module is in the Nim repo (just press 't' and type 'smtp')
13:38:50dom96|wThe NimForum source code is also on GitHub
13:38:54dom96|wUnder the nim-lang org
13:39:07dom96|wFeel free to create an issue on the nimforum repo
13:43:32euantordom can also probably create you a user manually if you can't get the emails
13:44:00euantorIt would be nice to add "login with GitHub" to the forums. I also still want to change the way sessions are handled and make some other changes when I get time
13:44:38MJCaleythanks, ya if i could get approved manually that'd be great in the meantime. I used the same username.
13:44:54MJCaleyi don't think it's the forum code that's the problem, just the Postfix config

15:07:08Araqso ... I'm thinking about how an ORM should be done for Nim
15:08:27YardanicoAraq, functional style or complete SQL - Nim objects mapping? For example this https://docs.ponyorm.com/ (ab) uses python generators
15:08:34Yardanicoto provide pythonic ORM
15:08:46Yardanicoselect(c for c in Customer if sum(c.orders.total_price) > 1000)
15:08:52YardanicoCustomer.select(lambda c: sum(c.orders.total_price) > 1000)
15:08:58*xet7 quit (Quit: Leaving)
15:09:00*xet7_ quit (Quit: Leaving)
15:09:22Yardanicoor maybe something simple like http://docs.peewee-orm.com/en/latest/peewee/quickstart.html
15:09:28*xet7 joined #nim
15:10:39Araqwell nothing like that
15:10:52FromGitter<ephja> does "simple" imply potentially slow?
15:11:18Yardanicowell pony orm converts your python generator expressions to SQL
15:11:38FromGitter<ephja> sqlalchemy seems to support most things, so it can probably be as fast as possible in most cases. I wonder if the complexity is justified though. some aspects are confusing
15:12:05Araqlet q = select:
15:12:05Araq tableA: (a, b, c, d)
15:12:05Araq tableB: (x, y, z)
15:12:07Araq where a == _ or c == _
15:12:20Araqfor stuff in q(4, "boo"): ...
15:12:21*Trustable joined #nim
15:12:31Yardanicowow
15:12:36Araq'select' is a macro that produces an interator
15:12:36Yardanicothat's actually nice
15:13:33Araqhowever, I want to read an SQL description via parsesql and check column, table names are correct and that the typing rules are adhered to
15:13:55FromGitter<ephja> it might have been the joins in sqlalchemy that weren't obvious
15:14:18FromGitter<ephja> do the official libraries only work with strings?
15:14:35Araqactually there is a "raw" accessor too
15:14:46Araqwhich I intend to use
15:14:56FromGitter<ephja> it's a good starting point, because it's simple and often fast enough I'm sure
15:14:58FromGitter<ephja> right
15:15:32AraqI'm not sure how to do the compiletime checking
15:15:33Yardanicowell I don't thing that ORM will be a bottleneck in some language like Nim :)
15:15:57Araqit should be optional
15:16:01Yardanicoyeah
15:16:16Araqthe question is mostly how to feed the 'select' macro the required information
15:18:46Araqalso it needs to support the queries as string literals
15:19:08Araqbecause often you tweak these in the db REPL and then paste them into your program
15:19:23Araqso a Nim'ish syntax is not all that great
15:26:34YardanicoAraq, also maybe a possibility to debug generated queries?
15:26:59YardanicoI mean that macro would echo them
15:27:26Araqsure but the macro does query checking against the schema
15:27:31Araqno need to debug things :P
15:27:45AraqI think this would work:
15:27:56AraqparseStmt(staticExec("ormin", "my.db"))
15:28:17Araqwhere 'ormin' is my helper tool that parses SQL and produces Nim code
15:30:05Araqbut hmmm if I have a tool that can parse SQL I might as well feed it the queries I need
15:30:26Yardanicohmm, it seems that appveyor doesn't offer 90-minute timeout for us anymore?
15:30:29Yardanicohttps://ci.appveyor.com/project/dom96/nim/build/230
15:30:35YardanicoBuild execution time has reached the maximum allowed time for your plan (60 minutes).
15:31:16Araqyeah suckers.
15:32:25Yardanicowhy Windows is generally slower at compiling software? not only nim
15:32:38Yardanicoah nvm
15:33:22Yardanicotravis ci has 2hr timeout
15:36:49Araqwe use gcc on windows, not really speedy
15:37:00Araqalso the tester is still not parallel

15:44:17dom96|wYou should take the approach that SQLAlchemy takes: many layers.
15:44:27dom96|wThe lowest layer abstracts the differences between SQL servers.
15:46:23Yardanicowell yeah, but sqlalchemy it's a bit too big
15:47:50Araqdom96|w: meh, that's lots of work and assumes one just pulled the decision of which DB to use out of one's ass
15:48:13Araqdifferent DBs have different strengths and different features
15:48:35Araqabstract over these differences if you don't care about features or speed
15:48:37dom96|wAraq: So are you just going to support postgresql
15:48:37dom96|w?
15:48:58Araqno, I support the db_* stuff we have
15:49:39Araqthat's 2 layers then I guess, not "many"
15:50:09Yardanicoso sqlite, postgresql, mysql?
15:50:36Araqyeah
15:50:38dom96|wso... you will be doing what I'm suggesting
15:51:03AraqI can bet SQLAlchemy uses more layers and 10x the amount of code
15:51:20dom96|wperhaps.
15:51:43dom96|wJust please consider this before implementing.

17:30:49krux02is there a solution to this problem: http://ix.io/zx7
17:31:47Yardanicokrux02, AFAIK no, only if you create additonal variable
17:32:01YardanicoI mean
17:32:08YardanicoI don't know if you can modify "data" this way
17:32:30krux02this is AFAIK something that nim really needs to be improved on
17:32:50krux02I hit this problem several times and at some point in tim this really need to be fixed
17:33:24Yardanicois there a way to modify item in "data" sequence inside of a grid? https://gist.github.com/Yardanico/e08a99c0172833ac3576a46e21d9ab14
17:33:53thomasross_is there an equivalent of python's pass keyword?

17:40:57Yardanicoafter you get needed value from vector you can change it and it'll be changed in vector too
17:41:01Yardanicobecause it's passed by reference
17:41:18YardanicoAFAIK you can't do "ref int"
17:42:11krux02you can do a reference to an int
17:42:16Yardanicohow?
17:42:23krux02it's just confusing on how it is named
17:42:27Yardanicoptr ?
17:42:38krux02proc foobar([...]): var int = ...
17:43:02krux02proc foobar(i: var int): var int = i
17:43:15krux02var i = 0; foobar(i) += 1
17:43:56krux02that is a real reference by the way, not like "ref"
17:44:10Yardanicowell I want something like this - https://gist.github.com/Yardanico/7076367b6bef065c813e865b99bbd8b4

17:45:13krux02welll you can't assign a reference to a variable
17:45:19krux02there you have to use a pointer

17:45:36krux02only in parameters and return values
17:46:47krux02but what you can do, is to declare a local template that expands to an expression
17:52:44Yardanicokrux02, ehm, but how? I've never written code in nim that needed stuff like this, so I don't know
17:56:09krux02Yardanico: template myVal = grid[5, 3]

20:08:21dom96I think you muted him a bit too early
20:08:33Yardanicothis seems to be the same person as before
20:08:34dom96People might say that we just mute anyone that criticises us, which isn't something we want.
20:08:40*dddddd quit (Ping timeout: 240 seconds)
20:08:57dom96this person didn't deserve to be muted IMO
20:10:16PMunchYeah, it should be allowed to criticize. Of course if you had showed him the source and he then continue to whine about then a mute might be in place :P
20:10:19*Trustable quit (Remote host closed the connection)
20:10:47dom96True.
20:11:21Yardanicodom96, btw, they didn't merge your PR sadly :( https://gitlab.com/gasche/gc-latency-experiment/merge_requests/16
20:11:50dom96They didn't merge anyone's
20:12:01Yardanicooh I see now
20:12:06Yardanicobad guys :D
20:12:16Yardanicowell they actually did

20:13:17dom96feel free to ping them
20:13:55Araqdom96: he PM'ed me afterwards
20:14:03Yardanicome too btw
20:14:18Araqoh interesting, troll or not?
20:14:27Yardanicohe was asking how to compile dom96's "snake"
20:14:57Yardanicowell I explained him how to do it
20:15:07dom96oh, ok
20:15:09dom96Fair
20:15:12Araq"those GC numbers on the homepage are probably just from a hello world app or something" is a troll
20:15:48*couven92 joined #nim
20:16:05dom96yes, but not one that deserves to be muted (yet)
20:16:08Araqhe can easily see it's not even our benchmark
20:16:16dom96but if he was PM'ing multiple people then he did deserve the mute
20:16:33Araq"why pretend to beat java and golang, languages who are developed by billion dollar companies who spend decades researching GCs?" is moreso a troll
20:19:50Yardanicowell maybe he can't understand the fact that nim, being a lot less popular/enterprise backed than go/java, can be actually better at some things
20:21:27Yardanicoisn't that a win if people actually compare compiled language without any runtime VM with interpreted dynamically typed language? (well sometimes it's a bad thing to compare)
20:21:44*dddddd joined #nim
20:23:28Yardanicoah guys

20:32:14mahmudovso i couldnt use intTostr
20:32:26Yardanicodom96, well I'm not finding you in IRC logs, but on the forums
20:32:32Yardanicofrom 2008-2010
20:33:37couven92Araq, for editDistance in unicode, is it okay if I just simply convert the strings to Rune-seqs instead... it just makes it it sooo much easier! :P
20:33:55Yardanicocouven92, well I cheated the same way :D
20:34:14Araqtold you it's not ok, learn how to blindly apply syntactic transformations please
20:34:33Araqyour math grades will thank you.
20:35:11Yardanicodom96, I didn't program at all when I was 12! https://social.msdn.microsoft.com/Forums/en-US/76baf3de-ef61-4657-920e-2c1f0a94643c/how-do-i-make-my-program-not-minimize-any-other-programs-when-my-program-runs
20:35:21couven92Araq, ich hab tatsächlich geschafft eine 3 im Mathe-LK im Abi zu bekommen... :(
20:35:21Yardanico(well maybe it's not you)
20:35:42Yardanicoit seems you've been programming since long time
20:35:43Araqcouven92: rate was ich hatte :P
20:35:48Yardanicotop 5% wow
20:36:07*relax joined #nim
20:36:08couven92okay... I juggle with it a little more... :P
20:36:43Araqlen --> runeLen, s[i] --> s.runeAt(i) inc(i) --> inc(i, s.runeLenAt(i))
20:37:00Araqthese 3 rules should suffice
20:37:01YardanicoAraq, didn't work for me last time I've tried
20:37:09YardanicoI'll try again
20:37:17dom96Yardanico: Yep. That's me. If you search for QuickScreenshot you might find what I was developing :)
20:37:22couven92I figured that I could just save and increase an offset with each more-than-one-char Rune... but that doesn't work, since the first row is initialized with the length
20:37:40couven92and I figures just using runeLen on the entire string would still be cheating
20:37:53Araqoh no, runeLen is allowed :P
20:37:57Araqsince it doesn't allocate
20:38:57couven92Araq, but it takes an entire additional pass through the strings!
20:39:06Yardanicocouven92, :D
20:42:54couven92Yeah, okay Araq, if I'm allowed to do runeLen, then it's really easy!
20:42:58*Yardanico quit (Remote host closed the connection)
20:43:02Araqtold ya.
20:44:02Araqin fact, you can do this:
20:44:16Araqtype UString = distinct string
20:44:34Araqproc len*(s: UString): int = runeLen(s)
20:45:00Araqproc `[]`*(a: UString; i: int): Rune = runeAt(a, i)
20:45:09couven92tja... do we want a distinct unicode string type in unicode.nim?
20:45:31Araqwell no, inc(i) cannot be transformed this way lol
20:46:08couven92yeah... but fastRuneAt basically does everything I need it to do, so...
21:06:35PMunchHmm, I'm starting to really like my Vim config now :)
21:06:55*yglukhov quit (Read error: Connection reset by peer)
21:07:03PMunchIt highlights spaces and tab indentation in a non-obtrusive way which is really nice for Nim
21:07:24PMunchSomething that's bugged me when writing in Vim that I couldn't always easily tell the indent level
21:07:47*yglukhov joined #nim
21:12:22couven92PMunch, I have that as well, here's mine: https://gist.github.com/couven92/f9649c9423a2ba2d34f8d008b448ec52

21:12:53couven92I also have render whitespace in every other editor on by default... :)
21:13:31PMunchThis is a bit more than render whitespace though
21:13:41PMunchIt only shows the character for indent levels
21:14:03PMunchhttps://github.com/Yggdroot/indentLine
21:14:11PMunchThat's the plugin (scroll down for images)
21:14:41PMunchAnd then I use a custom "set list" option to show tabs as a slightly heavier line
21:15:16PMunchhttp://ix.io/zxh
21:15:19PMunchThat's mine
21:15:42PMunchBut I've done some changes to the plugins (especially the Nim one), and made a custom colour scheme
21:16:19PMunchBrb, watching an episode of dollhouse
21:16:25couven92hmmm... indent guides are nice, yes... We got those in VS Code some time ago, and they've also been in Visual Studio a while now iirc
21:19:21FromGitter<adamrezich> should I be using ints for array indices?
