08:00:01FromGitter<superfunc_twitter> I think the table is immutable
08:00:11FromGitter<Bennyelg> seems like
08:00:16FromGitter<Bennyelg> but this is very strange lol
08:00:21FromGitter<superfunc_twitter> You'd need `var Table[string, string]`
08:00:26FromGitter<superfunc_twitter> in the type signature
08:00:59FromGitter<Bennyelg> I pass Table from another scope
08:01:06FromGitter<Bennyelg> I just want to add/ modify/delete keys from it
08:01:15FromGitter<Bennyelg> I need to ref to another object?
08:02:36*cspar_ quit (Ping timeout: 252 seconds)
08:03:23FromGitter<superfunc_twitter> if the table being passed in is a var, then you just need to change the type sig

08:05:20FromGitter<Bennyelg> how can I pass it as a var just x(var x: Table[..]) ?
08:05:31FromGitter<Bennyelg> how to cast Some() value to string

11:02:56flyxGrabli66: you need to make dosome() a template in order to capture the actual type of this
11:03:47flyxor at least that's what I expect
11:05:12FromGitter<Grabli66> I tried like this: template dosome(this : untyped) : untyped = echo this.type.name
11:05:16FromGitter<Grabli66> Also not works
11:08:19FromGitter<ChristianWitts> `echo this.name` works
11:09:19flyxGrabli66: echo name(this.type)
11:09:30flyxthat works with the proc version
11:10:16FromGitter<Grabli66> Great. It works
11:10:41flyxbut don't ask me why this.type.name does not
11:11:00FromGitter<Grabli66> Why it does not? :)

11:24:27*haha_ quit (Quit: haha_)
11:24:43Araqhmm after the VS code update indentation is super fucked up, yay
11:26:16couven92Araq, oh so it's like that with you too? I was wondering whether I had just fucked my settings... :O
11:26:26cremReading others' nim code, it's a bit hard to find meaning of idenfieir defined in different module. It's just not clear where to search. (And I don't have an idea how that could be fixed. Probably using IDEs is good enough, but if it's just a code on github, then it's not simple.)
11:26:43*crem is afraid to sound criticizing again.
11:29:02AraqI heard that a lot and it never made too much sense.
11:29:27Araqvar x: MyObject; x.foo # where does 'foo' come from?
11:30:05Araqanswer: chances are high from where MyObject comes from.
11:30:26Araqthat's the same for every other widespread language out there, Python, Ruby, C#...
11:32:19cremBut where MyObject comes from?
11:32:37AraqMyObject.nim or myobjects.nim
11:32:44Yardanicocrem, "go to definition" ? :)
11:32:48Araqthe jury is still out, most prefer MyObject.nim
11:32:55FromGitter<Bennyelg> how I can multiple string ? for example echo("=" * 10)
11:32:56cremThere's no "go to definition" on github.
11:33:01PMunchHard to do on GitHub Yardanico
11:33:07YardanicoBennyelg: strutils.repeat
11:33:15Yardanicoso like
11:33:16FromGitter<Bennyelg> Thanks
11:33:20Yardanicoecho("=".repeat(10))
11:33:35Araqmaybe github is a primitive environment for code navigation. big surprise
11:34:30FromGitter<Bennyelg> Thanks.
11:35:51PMunchHaha, that's true Araq
11:36:07PMunchAnd I guess the problem here is more to do with people stylistic choices than anything else
11:36:13YardanicoAraq, crem, "go to definition" ? :)
11:36:16FromGitter<Grabli66> Maybe make a special command for compiler to list all procs with module name for some type? Example: nim proclist main.nim MyObject
11:36:16Yardanicooh sorry

11:37:07PMunchGrabli66 can't nimsuggest do that already?
11:37:15Yardanicoit can
11:37:23Yardanicobut not as a separate cmd afaik
11:37:50FromGitter<Grabli66> It can? Cool. I did not know
11:38:08Yardanicoit definitely can
11:38:13Yardanicobecause nimsuggest uses compiler :)
11:38:21FromGitter<Grabli66> Great
11:38:49FromGitter<Grabli66> Then, there is no problem at all :)
11:39:25*Arrrr joined #nim
11:40:53FromGitter<Grabli66> Hhhm. Nimsuggest is a tool for IDE? I can't use this from console?
11:41:56Yardanicoyou definitely can
11:42:05Yardanicobut yes, it's mostly for IDEs and text editors
11:43:04Yardanicoe.g. you can use it in vim/emacs/vscode/sublime (with nim plugins)
11:43:08Yardanicoalso in notepad++
11:43:19FromGitter<Grabli66> Ok. Tell me how i can get all procs for some type with nimsuggest. I don't see any command for that in nimsuggest
11:43:36Yardaniconimsuggest operates on files
11:44:42Yardanicohttps://nim-lang.org/docs/nimsuggest.html
11:47:25Araqgrabli66: that's 'nim doc2 foo.nim' and then "group by type"
11:50:58YardanicoAraq, are nim docs regenerated after new release?
11:51:01couven92Araq, BTW, editDistance for Unicode is not as simple as you suggested, you cannot easily get the upper or lower triangles (whatever those are) because there is no easily calcultable half of the string
11:51:51FromGitter<Grabli66> Great. I created documentation. But it's not what i want. In my source code, i use a "Request" object. And i want a list of all procedures, with module names that can be used with that object.
11:53:42PMunchcouven92, wouldn't you just handle them separately as glyphs?
11:53:51PMunchOr runes rather
11:54:06YardanicoPMunch, well
11:54:10Yardanicothis is slower
11:54:23couven92PMunch, I would, but Araq won't let be convert the string to runes, since it creates (very much) memory allocation overhead
11:54:38YardanicoI've implemented it with two runes sequences (the most inefficient way), and it was 20x slower than ascii version
11:55:58PMunchAah
11:56:22Yardanicowell it still can be done faster
11:56:25Yardanicobecause I choose the easy way
11:56:40Yardanico(store two seqs of each string runes)
11:56:56FromGitter<Bennyelg> way i cant do this: typeMapping.keys.join(",")
11:57:08AraqGrabli66: so ... and how do you think this can work? nimsuggest compiles any .nim file out there for you to answer that question?
11:57:23AraqtoSeq(typeMapping.keys).join","
11:57:27Yardanicoyeah
11:57:33Yardanicothere's a feature request on github btw
11:57:38Yardanicofor this exact proc
11:57:55Yardanicohttps://github.com/nim-lang/Nim/issues/943
11:58:17Yardanicowell it would be easy to add "keys" proc which will return a seq
11:58:25Yardanicobut I don't know if it would be a good addition to stdlib
11:58:25FromGitter<Bennyelg> @Araq it's not working
11:58:29Yardanicoimport sequtils
11:58:38FromGitter<Bennyelg> undecleard field 'keys'
11:58:40Yardanicoah
11:58:44Yardanicowait
11:58:50Yardanicowhat is your "typeMapping" ?
11:59:09FromGitter<Grabli66> <Araq>, i think that nimsuggest can get all imported files for module, and get all procedures for type :)
11:59:12Yardanicoif you want to have something like a dictionary
11:59:16Yardanicoyou should use tables
11:59:17*Kingsquee quit (Remote host closed the connection)
11:59:32Yardanico{a: b, c: d} is just a syntax sugar for openarray[(value, value)]
11:59:37Yardanicohttps://nim-lang.org/docs/tables.html
11:59:49FromGitter<Bennyelg> typeMapping is a OrederdDict
11:59:54Yardanicoah
12:00:00Yardanicoordered dict?
12:00:00Yardanicowhat
12:00:18Yardanicomaybe ordered table?
12:00:23Araqbut then you already know the modules because you imported them, but yeah, nimsuggest can do that use an editor with nimsuggest support
12:01:20YardanicoAraq, what is the easiest way to make a link which will point to some proc/type in nim-generated docs?
12:01:21FromGitter<k0pernicus> Can we compute, at compile time, a regular expression?
12:01:42Yardanicono, because it requires C ffi
12:01:52Yardanicoand pegs doesn't work at compile-time AFAIK
12:01:53FromGitter<Bennyelg> yea it's ordered table
12:01:54Yardanicomaybe it was fixed
12:02:00FromGitter<Bennyelg> but now How I get only the keys
12:02:02Araqit wasn't
12:02:11FromGitter<k0pernicus> Aaah ok - I understand now the message `cannot 'importc' variable at compile time`
12:02:12AraqtoSeq(foo.keys)
12:02:28Yardanicoimport sequtils
12:02:30Yardanicoimport strutils
12:02:30YardanicotoSeq(foo.keys).join(",")
12:02:36Arrrryou can make a program and call it in compile time
12:02:38Yardanicoif you have "foo" declared
12:02:43FromGitter<Bennyelg> as I said "Undecleared keys"
12:02:51Yardanicoshow full source code please?
12:03:00FromGitter<Grabli66> <Araq>, i use VS code. But i think it can't show me that information, or i don't know how to show it.
12:03:06Yardanicoit can
12:03:09Yardanicowith nim plugin
12:03:18FromGitter<Grabli66> I use nim plugin

12:03:27AraqGlabli66: you need to configure it
12:03:37FromGitter<Bennyelg> var x = parseTypes()
12:03:53FromGitter<Bennyelg> toSeq(x.keys).join(",") not working
12:04:07FromGitter<Grabli66> <Araq>, Is there a documentation how?
12:04:32FromGitter<Grabli66> Ok. I'll try to find
12:04:39YardanicoBennyelg: can you show full source code please
12:04:43Yardanicoe.g. which can compile separately
12:06:00YardanicoAraq, also, if I really know the size of seq, should I divide this size by 1.5? because as you said there's 1.5x of size you've specified
12:06:11Yardanicoah, no
12:06:13Yardanicoit's for "add"
12:07:41Araqyeah
12:10:55Yardanicoyou wouldn't believe this: in comments for two-year old article about Nim someone has left feedback like "nim is python in the javascript programmer's ass". So he thinks that Nim "stole" let/const from JS :D
12:12:17cremThere's no let/const in javascript (at least as of ES5), there are ones in typescript though.
12:12:28Yardanicocrem, there is in ES2015

12:14:23cremprobably taken from typescript then, which surely had let/const in 2010. That's weird that it's stated as being released in 2012 as I'm sure I read docs about it before 2011.
12:15:38FromGitter<Yardanico> Well anyway this guy said this without any arguments :)

12:19:10AraqI took 'const' and 'var' from Pascal and 'let' from ML ...
12:19:33AraqTypescript/JS had no influence on Nim's design whatsoever
12:20:09FromGitter<Bennyelg> Any library which check if the import is unused?
12:20:10cremI like that declaring constant variable (which is safer) is not longer than declaring mutable one.
12:21:12AraqBennyelg, use nimsuggest, remove imports until the code stops working or just leave it, nobody gives a fuck about unused imports
12:21:20Araqthey don't cause any harm

12:33:19FromGitter<Grabli66> Ok. Is it ready for production?
12:33:51Yardanicoask Araq, but I think he uses it, or someone from Xored
12:34:30FromGitter<Grabli66> Good. Need to try.

12:36:02Yardanicohow it's so fast?
12:36:09Yardanicoah, JS doesn't requires compilation

12:38:27FromGitter<stisa> @Bennyelg https://nimble.directory ?
12:38:29YardanicoWell nimble stores all package entries on github
12:38:32Yardanicobut yeah, use nimble.directory

12:45:31FromGitter<k0pernicus> Crem > https://github.com/nim-lang/Nim :-)
12:45:36Yardaniconake is Makefile-like thing which allows you to write ANY nim code to describe your tasks

12:46:20Yardanicocrem, also, about nake - nimble with .nims files seems better
12:46:25FromGitter<Bennyelg> nice, i create everything and it's pretty ready

12:57:34Yardanicoyeah
12:57:47couven92def-, thanks! :)
12:58:02Yardanicoguys, noSideEffect is used by compiler to remove unused code?
12:58:49def-Not that I know of, but it could be in the future
12:59:08def-I think it's mostly used to check that you don't accidentally call something with side effects inside
12:59:15Yardanicoyeah I know about that
12:59:39*rauss joined #nim
13:02:29FromGitter<Grabli66> Nim programmer should avoid side effects? :)
13:02:50Yardanicono
13:02:58Yardanicoit's just here if programmer wants to know it
13:03:10couven92do we have do-while in Nim?
13:03:18def-couven92: you can make your own
13:03:19Yardanicono, but you can easily implement your do-while :P
13:03:27couven92:)
13:03:36Yardanicoit's pretty straightforward
13:03:37def-https://github.com/def-/nim-unsorted/blob/master/dowhile.nim
13:03:57def-(or use while true: ... if not a: break)
13:05:28FromGitter<Grabli66> Should nim developer avoid "try/catch", for better performance?
13:05:51couven92def-, Yardanico, yeah I know... I was just wondering, it's so rarely used in C#, C, etc., that I did know whether I just hadn't seen any do-whiles or whether it just not exists :)
13:07:57*haha_ quit (Quit: haha_)
13:14:59Yardanicodef-, looking at this - https://github.com/def-/nim-unsorted/blob/master/forest/funMagicForest.nim
13:15:15Yardanicomaybe we should add new proc like filterIt, but which will allow you to write the name of variable you want to use

13:19:14Yardanicoand also with nimsuggest this would be VERY easy
13:19:34Yardanicocrem, and also this "nico" is just a copy of this https://github.com/ftsf/nico
13:19:51def-Yardanico: i don't like to use templates too much
13:19:55Yardanicoso ftsf copied it to make distribution easier maybe
13:20:22Yardanicodef-, well, with them you can reduce the need for manually write types everywhere :)

14:37:40FromGitter<k0pernicus> Yep, it’s good :-)
14:37:46FromGitter<k0pernicus> Thanks a lot @Yardanico :-)
14:37:47Yardanicoalso, why do you need "try" "except" in when isMainModule ?
14:37:57Yardanicoyou're not accessing any keys here
14:38:05Yardanicoyou should add try except in your get_json_nodes
14:38:24Yardanicobecause data will contain nim object
14:38:29Yardanicoso KeyError can't happen here
14:38:35FromGitter<k0pernicus> It’s a mistake actually
14:38:39*claudiuinberlin joined #nim
14:38:49FromGitter<k0pernicus> I forgot to copy that line after the `try` statement: `let data = to(node.get(), FeaturesTemplate)`
14:38:54Yardanicoah
14:38:55Yardanicook :)
14:39:00FromGitter<k0pernicus> Sorry for that :-)
14:39:26FromGitter<k0pernicus> Maybe I can avoid to “translate” my JSON datastructure into an object...
14:39:58Yardanicowell yeah, your program will take a bit less RAM maybe
14:40:00Yardanicoand will be a bit faster
14:40:09FromGitter<k0pernicus> So, instead of `let data = to(node.get(), FeaturesTemplate`, just grab the information I needed...
14:40:22FromGitter<k0pernicus> I will try a new version
14:40:49Yardanicoalso
14:40:55*claudiuinberlin quit (Client Quit)
14:41:21Yardanicoyou may also try to remove regex pattern of files :) well I don't really know if it will speed up or slow down your code
14:41:44YardanicoI mean to replace it with pegs/strscans if applicable
14:41:46Yardanicobut regexs are fine too
14:42:00FromGitter<k0pernicus> Yep, maybe try an `.endsWith(“.json”)` thing
14:42:18Yardanicoah
14:42:32YardanicoI thought you really need that regex to check if filename starts with some word :)
14:42:46FromGitter<k0pernicus> Later yes
14:43:05FromGitter<k0pernicus> But I can experiment without in order to get some speed results
14:43:08FromGitter<k0pernicus> ;-)
14:43:24FromGitter<k0pernicus> `pegs/strscans` -> I will check that

14:46:35FromGitter<k0pernicus> Do you know how to extract a sequence from a `JsonNode` type?
14:46:47FromGitter<k0pernicus> I see `getStr` to extract a string for example...
14:48:40Yardanicok0pernicus
14:48:57Yardanicohttps://nim-lang.org/docs/json.html#getElems,JsonNode,seq[JsonNode]
14:49:05Yardanicoso you would get seq[JsonNode]
14:49:25Yardanicoand if you iterate over it, you'll able to do "iterval.str"
14:49:44FromGitter<k0pernicus> Oh ok
14:49:58FromGitter<k0pernicus> So, a sequence is actually a seq of JsonNode (string) ?
14:50:24Yardanicowell it's just a seq of JsonNode
14:50:35FromGitter<k0pernicus> Yeah, right
14:50:40Yardanicobecause Nim can't prove that some field in json will be a string or not
14:51:18FromGitter<k0pernicus> Ok, done :-)
14:53:15FromGitter<k0pernicus> Hmmm...
14:53:29FromGitter<k0pernicus> Actually, without “translation”, it’s worth
14:53:54FromGitter<k0pernicus> 3 seconds more for the non-released version, 1 second more the released version
14:54:45Yardanicowell times can differ
14:55:02Yardanico"time" isn't reliable, but if it's slower for you - use "translation" :)

16:11:30FromGitter<k0pernicus> (so, the last one)
16:12:59PMunchHmm interesting Yardanico. But it seem like he made a simple parser for his own game only.
16:13:06PMunchSo it's not really generic
16:13:11YardanicoPMunch, https://github.com/Tormund/rod_tilemap ?
16:13:16Yardanicowell yeah it's for rod too
16:13:32YardanicoPMunch,
16:13:34YardanicoI found this - https://github.com/jsudlow/nimtmapreader
16:13:51Yardanicowell it doesn't seem to support tmx
16:14:37PMunchAh, Tiled can export to both xml and json
16:14:44FromGitter<k0pernicus> It’s ok, I saw the problem :-)
16:14:48FromGitter<Yardanico> @k0pernicus also
16:14:50FromGitter<Yardanico> for better performance
16:14:54FromGitter<k0pernicus> ‘,’ instead of ‘:'
16:14:56FromGitter<k0pernicus> Yep?
16:15:01FromGitter<Yardanico> Don't use var current_indexes: seq[int] = repeat(0, len_features_vector)
16:15:14FromGitter<Yardanico> use var current_indexes: seq[int] = newSeqint (len_features_vector)
16:15:17FromGitter<Yardanico> oh
16:15:21FromGitter<Yardanico> wait a sec :)
16:15:47FromGitter<Yardanico> @k0pernicus use this: https://gist.github.com/Yardanico/28fc7a75e34eabb694158cb2104fb09f
16:15:50PMunchSo support for .tmx which is the xml format isn't really an issue as you can simply export as json
16:16:04*yglukhov joined #nim
16:16:11FromGitter<Yardanico> and you can use it the same way
16:16:12FromGitter<k0pernicus> Thanks @Yardanico
16:16:17FromGitter<k0pernicus> Default values, like for Go?
16:16:25FromGitter<Yardanico> well they're really "default"
16:16:40FromGitter<Yardanico> so all non-ref types have default values - just binary "0"
16:16:50FromGitter<Yardanico> for int this is 0, for float - 0.0, for bool - false

16:30:48FromGitter<k0pernicus> Oh right!
16:30:55FromGitter<k0pernicus> But
16:31:10FromGitter<k0pernicus> I will insert the JArray in JObject later, no?
16:31:38FromGitter<Yardanico> you actually don't need to do that
16:31:43FromGitter<k0pernicus> Oh ok
16:31:46FromGitter<k0pernicus> Great
16:31:48FromGitter<Yardanico> [{"6511":[3,2,2,1,4]},{"5":[1,2,3,4,5]}] is a valid json
16:32:01FromGitter<k0pernicus> Ok, pretty cool :-)

16:45:09miranguys, any easy way to do a[start:stop:step] in nim?
16:45:19*Sentreen quit (Ping timeout: 248 seconds)
16:45:47miranfor example, i want just odd elements of some sequence
16:47:00Yardanicomiran, yes
16:47:03Yardanicocountup supports step
16:47:29Yardanicocouven92: let me try :)
16:47:42Yardanicocouven92: and araq means - get rid of debugEcho's
16:48:00mirani know about countup, but i cannot just do: `a[countup(0, 10, 2)]`
16:48:06Yardanicomiran, well yeah you can't
16:48:08Yardanicouse "for" loop
16:48:57miranyeah, for loop was my first solution. i thought there might be something more convenient
16:49:03FromGitter<couven92> @Yardanico yeah, I realized that when I stepped into the bus :P will do that immediately once I'm home
16:49:13Yardanicowell I'll try it anyway
16:50:00Yardanicocouven92: also there's some unused variables in your implementation :) but it looks very cool anyway
16:50:16Yardanicotwo unused vars
16:50:19Yardanicolen_chars_a and len_chars_b
16:51:25FromGitter<couven92> Really :O, ah, yes, yeah I'll delete those... apparently it was really time for me to get home if I have been *that* inattentive
16:51:37Yardanicowell you're a legend
16:52:07Yardanicoyou're really a legend! unicode editdistance is only 4x slower (40ns vs 10ns) vs strutils editDistance
16:52:11FromGitter<k0pernicus> *Love is in the air…*
16:52:20FromGitter<couven92> Hmm

16:52:47FromGitter<Yardanico> but strutils is only ascii
16:52:54FromGitter<Yardanico> and your proc is every character from unicode :)
16:53:20FromGitter<Yardanico> also I think maybe *somewhere* in the future we'll make unicode module the default for string operations?
16:53:25FromGitter<Yardanico> or no?
16:53:46FromGitter<couven92> Yeah, it has to iterate through both strings to count runes though...
16:54:15FromGitter<couven92> Ascii doesn't need that
16:54:42YardanicoI think this is a good performance
16:54:58Yardanicolol
16:55:32Yardanicowith gcc and ascii strings your proc is only 2x slower than pure-ascii version
16:55:46Yardanicoand with gcc and unicode string it's only 3.4x slower
16:55:46FromGitter<couven92> I have one more optimization in mind, let's see if that helps
16:58:29def-miran: something like this? https://gist.github.com/def-/b2a308b705865ad182121df0a4688cfd

17:03:52Yardanicobut if you want to use it - you should "include" it, not import

17:04:08YardanicoI mean type and all template/proc names
17:05:08Yardanicoit has almost the same performance as countup
17:05:24miranthanks Yardanico, will take a look
17:05:34Yardanicobecause it uses the same algorithm as countup for iterating :)
17:05:49YardanicoAnd I ported some code from JS library with python-like range

17:23:26programistocould someone clarify the semantics of returning var variable vs variable froma function?
17:23:38programistois result within the function body var or does tht also have an impact outside of the function
17:24:07Yardanicoprogramisto, if you get a value from table and return it as "var Type", user will be able to modify it
17:24:09couven92you can return var variable? :O
17:24:12Yardanicoand it will be modified in table
17:24:13Yardanicocouven92, yes

17:25:56Yardanicowell it's not needed very often for your own programs
17:26:00Yardanicobut it's needed for stdlib
17:26:01Yardanicoalso
17:26:04Yardanicoyou can return "ref Type"
17:26:09Yardanicoor also you can do this
17:27:03programistocould I tell you guys my secret? nim is kind of addictive
17:27:21programistothat pythonicness combined with mapping so closely to C is fun
17:27:27programistovery easy to understand what's going on
17:27:40Yardanicoprogramisto, also don't forget lisp macros :D
17:28:18programistoyeah wow
17:28:20Yardanicoprogramisto, also not only C, but C++ and ObjC
17:28:22Yardanicoand even JS :P
17:28:32programistokind of feel sorry for those bums getting hyped into stuff like rust
17:28:59programistonim is like the greatest language ever, why is it not more popular
17:29:33programistosorry, it's just fun

17:30:26programistoyeah, the dynamkc makes sense
17:30:33*claudiuinberlin joined #nim
17:30:47programistoI think if you sat down 8/10 programmers and had them evaluate nim and rust for the average programs they'd put together, nim is a win almost every time
17:31:02programistoit just has the right combination of expressivenexs and low level acccess
17:31:28programistothat goese for go, maybe even python, though that's more dependent on library access
17:39:11Yardanicowell also about any big rust program: it would still have crashes
17:39:22Yardanicobecause big programs usually interact with something other than rust code
17:39:50Yardanicoalso TIL that Rust doesn't check for out of bounds in compile-time
17:39:53Yardanicoit does that in runtime
17:41:14Yardanicoand I'm not joking here

20:49:50PMunchBut I was trying to add some simple += -= functions for uint32 and int32, that would detect overflow/underflow and just max or min out the uint value
