| 00:15:25 | dom96 | I'm curious why mit has Nim docs. |
| 00:17:25 | flaviu | They seem to have some sort of internal package manager. |
| 00:17:46 | flaviu | So I assume they got built while creating the internal package. |
| 00:19:43 | * | cjbest quit (Quit: My Mac has gone to sleep. ZZZzzz…) |
| 00:20:46 | flaviu | Nim has pretty high per-invocation overhead. |
| 00:21:01 | flaviu | I can only do ~9 invocations/sec |
| 00:25:08 | * | Demon_Fox joined #nim |
| 00:25:21 | reactormonk | flaviu, only? ^^ |
| 00:26:03 | flaviu | That's high. My small virtual machine can do ~4000 invocations/sec. |
| 00:26:56 | flaviu | Fuzz testers aren't practical unless it's possible to keep things in the thousands of invocations per second. |
| 00:31:31 | dom96 | invocations? |
| 00:32:54 | flaviu | Literally invoking the compiler. |
| 00:33:43 | dom96 | Ahh yes. It does have to go through gcc after all. |
| 00:36:52 | def- | flaviu: you want to fuzz nim? |

| 00:38:56 | def- | Actually that reminds me that I should disclose a vulnerability soon because it's not getting fixed |
| 00:39:34 | flaviu | Nice! I've only been using it for a pet project, but I like that you've been doing productive work with it :P |
| 00:39:51 | flaviu | dom96: skipping GCC makes it ~2% faster, not too big a difference. |
| 00:40:20 | def- | flaviu: clearly, make nim faster, then fuzz it |
| 00:40:48 | flaviu | Looks like lots of the time is in dynamic memory management, so that might not be so easy. |
| 00:42:10 | dom96 | def-: vulnerability? In Nim? |
| 00:42:54 | def- | dom96: nono, in a commonly used library |
| 00:43:53 | dom96 | def-: i'm curious, tell me more. |

| 13:11:20 | ekarlso | reactormonk: how you mean to iterate over types ? |
| 13:11:38 | reactormonk | ekarlso, so you wouldn't have to copy/paste. I suppose you could just go with a template |
| 13:14:14 | ekarlso | reactormonk: never used templates but always time to learn I guess :p |
| 13:14:21 | EXetoC | reactormonk: with fieldPairs and typeinfo? |
| 13:14:46 | reactormonk | EXetoC, now that's something I would have to look up |
| 13:15:30 | EXetoC | the typeinfo module that is. the marshal module uses it |
| 13:16:06 | ekarlso | EXetoC: ? ^ |
| 13:18:57 | EXetoC | ekarlso: for doing type reflection |
| 13:19:23 | ekarlso | hmm k |
| 13:20:32 | ekarlso | hmmms |
| 13:20:46 | ekarlso | so in rust they store T for what type the field is gonna be |
| 13:20:52 | ekarlso | how the stuffs u do that in nim ? |
| 13:22:59 | EXetoC | reactormonk: have you seen the maybe_t (option) module? |
| 13:23:10 | EXetoC | ekarlso: the typeinfo modules allows you to iterate through the fields of a type and get their names and types |
| 13:23:23 | ekarlso | EXetoC: oh, awesome |
| 13:23:38 | ekarlso | EXetoC: but wondering for a "Field" type how to store what type that field is supposed to be |
| 13:24:57 | reactormonk | ekarlso, nope, link plz |
| 13:25:15 | ekarlso | reactormonk: ? |
| 13:25:20 | reactormonk | @ EXetoC |
| 13:25:21 | EXetoC | reactormonk: you mean me? https://github.com/fowlmouth/nimlibs/blob/master/fowltek/maybe_t.nim |
| 13:25:39 | EXetoC | ekarlso: do you need to? if so then with a table perhaps |
| 13:25:54 | ekarlso | EXetoC: why a table ? |
| 13:26:33 | reactormonk | EXetoC, any map around? |
| 13:26:45 | reactormonk | I'd expect at least an iterator ^^ |
| 13:26:52 | * | SplinterOfChaos joined #nim |

| 13:37:26 | ekarlso | db_utils.nim(12, 41) Error: undeclared identifier: 'T' |
| 13:37:30 | ekarlso | then :/ |
| 13:37:43 | reactormonk | ekarlso, O.o |
| 13:37:57 | ekarlso | do you need to pass T for table as well ? |
| 13:38:04 | reactormonk | ekarlso, btw, check do_* for sql stuff |
| 13:38:07 | ekarlso | doesn't exactly make sense |
| 13:38:16 | EXetoC | ekarlso: either you make Table generic too (Table[T]) or you instantiate Column there and then (Column[int]) for example |
| 13:38:38 | ekarlso | sigh, u can't have a Table of just string :p |
| 13:38:50 | EXetoC | instantiations cannot happen at runtime. if you want something along those lines then perhaps you want to rely on object variants instead |
| 13:39:27 | ekarlso | sigh, so generics aint allowed for tables... |
| 13:39:30 | ekarlso | doh |
| 13:40:03 | reactormonk | ekarlso, yes, they are. Just don't make name collisions |
| 13:40:12 | EXetoC | perhaps there's some obscure way of getting it to work, at *compile time* |
| 13:40:24 | EXetoC | really. ok |
| 13:40:49 | ekarlso | reactormonk: sorry ? |
| 13:41:01 | EXetoC | reactormonk: I think he means Table[string, typedesc] |
| 13:41:15 | ekarlso | db_utils.nim(12, 22) Error: no generic parameters allowed for Table |
| 13:41:17 | ekarlso | -,,- |
| 13:41:23 | ekarlso | believe me I tried :p |
| 13:42:13 | ekarlso | reactormonk: how you mean name collisions ? |
| 13:42:23 | EXetoC | it's not directly related to tables. you can't do "foo: Column" either |
| 13:42:50 | EXetoC | typeinfo might be what you want as I said, and the marshal module shows how it can be used |
| 13:43:18 | ekarlso | I wanna be able to define how a table looks in nim-lang with columns basically |
| 13:44:18 | reactormonk | ekarlso, you're importing tables, which defines Table |
| 13:44:25 | ekarlso | ahhh |
| 13:44:27 | ekarlso | hah |
| 13:45:36 | EXetoC | is it causing problems? if so, qualify those symbols or rename your type |
| 13:45:37 | * | ehaliewicz quit (Read error: Connection reset by peer) |
| 13:46:31 | EXetoC | qualify with the module name containing the type that you want |
| 13:47:00 | ekarlso | nono, just so stupid that I forgot that there's Table already defined ;) |
| 13:47:02 | ekarlso | db_utils.nim(16, 16) Error: invalid type: 'None' in this context: 'proc (string, string): DbTable' |
| 13:47:05 | ekarlso | hmm |
| 13:47:30 | ekarlso | dont get it what's None there |
| 13:47:41 | reactormonk | something, give code |
| 13:48:04 | ekarlso | reactormonk: sure thing: https://bpaste.net/show/beb998b801ac |
| 13:49:13 | ekarlso | but I guess a generic is kinda weird too since the "data" field is never gonna be used :/ |
| 13:49:49 | ekarlso | what they're doing in rust is storing what type the field is gonna be loaded as |
| 13:50:54 | reactormonk | ekarlso, sooo what exactly are you trying to achieve? |
| 13:51:27 | ekarlso | reactormonk: defined a DbTable and it's DbColumns |
| 13:52:09 | ekarlso | but store the type that a column is eventually going to be |
| 13:53:03 | reactormonk | ekarlso, so you want to store the type information of a table? |
| 13:53:16 | ekarlso | reactormonk: yea |
| 13:53:18 | * | gokr_ quit (Ping timeout: 245 seconds) |
| 13:53:27 | ekarlso | rather speaking I wanna store what type a column is |
| 13:53:37 | ekarlso | is it a string, float, int or whatever |
| 13:53:59 | reactormonk | Do you know that at compiletime or runtime? |
| 13:54:28 | ekarlso | compiletime, database doesn't change when you're running typically :P |
| 13:54:39 | reactormonk | it might change when you're altering |
| 13:55:04 | ekarlso | true enough |
| 13:56:06 | reactormonk | How do you want to propagate the types into the typesystem? |
| 13:56:27 | ekarlso | how you mean ? :) |
| 13:57:03 | EXetoC | is this an ORM you're creating? |
| 13:57:04 | reactormonk | You gotta tell nim somehow which type something is, so you can e.g. var foo: int = <some expression that fetches it from the table> |
| 13:57:53 | ekarlso | EXetoC: more like a way to build queries at first was the plan.. |
| 13:59:04 | reactormonk | EXetoC, typedesc is runtime or compiletime? |
| 13:59:45 | EXetoC | reactormonk: compile time. generic parameters are typedescs |
| 14:00:36 | reactormonk | EXetoC, so what happens when I have var t: Table[string, typedesc] and go t["foo"]? |
| 14:02:42 | EXetoC | reactormonk: it doesn't work |
| 14:03:33 | reactormonk | ekarlso, that's where the None comes from - you can't use typedesc because that's None after compiling it |

| 14:05:17 | ekarlso | darn :) |
| 14:05:44 | reactormonk | ekarlso, I think you might want to go with templates here and think on how exactly you want to deal with it |
| 14:05:44 | EXetoC | ekarlso: rust is storing the type of what exactly? |
| 14:06:29 | ekarlso | EXetoC: the db column |
| 14:06:52 | EXetoC | you need that for query *building*? |
| 14:07:51 | ekarlso | guess not .. |
| 14:08:08 | ekarlso | not sure why they store the type info |
| 14:08:11 | ekarlso | i'll dig into that |
| 14:11:22 | ekarlso | but wouldn't be wrong to have a thing that could help marshal db rows to objects.. |
| 14:12:43 | EXetoC | that's more than just querying then, but shouldn't you just rely on the SQL API in order to perform type validations at run-time? |
| 14:13:16 | ekarlso | EXetoC: eh, well atm it doesn't .. |
| 14:13:26 | ekarlso | TRow is just a seq of strings.. |
| 14:15:04 | EXetoC | you can attempt to convert to int then for example, and see if it works |
| 14:15:35 | ekarlso | that's what I'm doing atm... parseInt(row[0]) |
| 14:18:14 | ekarlso | still would be kinda nice to have a util that generated the sql programmatically then you executed a query, fed it the row and your object or smth like that and returned a instance of the object populated |
| 14:18:32 | ekarlso | but that's 2 sept. libraries |
| 14:20:16 | Araq_ | hey guys. I'm back |
| 14:23:05 | ekarlso | EXetoC: or is that wishful thinking ? :) |
| 14:25:19 | * | barosl quit (Quit: Leaving) |
| 14:25:55 | ekarlso | reactormonk: regarding alter table, yeah but stuff like sqla core still defined the table in a python file like "this is my table" so if you change a column type underneath it will blow up |
| 14:26:25 | reactormonk | Araq_, time for some coding? |
| 14:27:09 | Araq_ | reactormonk: what makes you think I'm not coding all the time? |
| 14:27:37 | reactormonk | Araq_, that you have to announce you're back |
| 14:28:14 | ekarlso | reactormonk: you think my usecase is weird ? |
| 14:29:01 | reactormonk | ekarlso, no, buy your approach is incorrect. |
| 14:29:13 | ekarlso | hmmms |
| 14:30:11 | ekarlso | reactormonk: sugestions ? |
| 14:30:28 | Araq_ | ekarlso: IMO an ORM should read the database model from the database and generate type safe Nim code to access it. but you need to have LINQ-like query building and it's lots of work |
| 14:30:32 | reactormonk | ekarlso, you could make an ORM by using said fieldPairs and templates to generate the procs |
| 14:30:53 | reactormonk | Araq_, so you wanna read the DB at compiletime? |
| 14:31:36 | Araq_ | no. it's an external tool that generates Nim code. you *can* do it at compiletime but I don't see the point |
| 14:31:39 | EXetoC | ekarlso: what I suggested would be the basis for that, since some kind of type information must be available |
| 14:32:09 | Araq_ | it's likely a slowish operation so you either cache it or you don't do it at compile-time |
| 14:32:22 | ekarlso | meh, i give up :p |
| 14:33:27 | ekarlso | sounds like something that's above my knowledge grade atm for nim :) |
| 14:33:43 | Araq_ | ekarlso: it's not Nim specific really. |
| 14:33:58 | Araq_ | it's just a code generator |
| 14:34:23 | ekarlso | Araq_: well never done those either :) |
| 14:36:25 | ekarlso | Araq_: but most libraries like that doesn't do it that way ? |
| 14:36:36 | EXetoC | just start small and add things incrementally if you want to learn. it should be much easier to start with only the type matching |
| 14:38:29 | Araq_ | ekarlso: LinqToSql does it this way. |
| 14:39:24 | * | davidhq quit (Quit: My MacBook Pro has gone to sleep. ZZZzzz…) |

| 14:42:54 | EXetoC | ekarlso: "for name, val in obj.fieldPairs: if name == columnName: if areCompatible(val.type.toKind, columnKind): val = columnValue else: <handle type mismatch>" |
| 14:42:59 | Araq_ | for static typing |
| 14:44:02 | Araq_ | EXetoC: that is a nice 70% solution :-) |
| 14:44:11 | EXetoC | I don't know how far you can go with fieldPairs though. recursive iteration might work |
| 14:45:34 | Araq_ | EXetoC: that's an implementation for getColumns[MyObjType](query), right? |
| 14:45:42 | EXetoC | not that standard SQL can yield trees or anything |
| 14:46:12 | Araq_ | if you do the join implicitly, it can |
| 14:47:32 | EXetoC | ok |

| 17:36:59 | * | sillesta joined #nim |
| 17:37:01 | novist | well that bit surely was ugly. and totally not intuitive |
| 17:38:22 | novist | since you here Araq_.. can virtual c++ class methods be overloaded in nim easily? reactormonk that not rly. but i was thinking maybe you would know some magic trick |
| 17:38:47 | * | MajorWork quit (Quit: Leaving) |
| 17:39:03 | Araq_ | you mean 'override', right? overloading is different |
| 17:39:43 | novist | actually i mean pure virtual, sorry |
| 17:39:50 | Araq_ | and yeah, you cannot. C++ support has been improved tremendously in the devel version of the compiler. for instance Nim can generate template instantiations |
| 17:39:59 | Araq_ | now |
| 17:40:12 | Araq_ | but overriding a virtual method is still not possible. |
| 17:40:43 | novist | think it will come before 1.0? its pretty much mandatory for using serious c++ stuff. be it game engines or even Qt. |
| 17:40:59 | Araq_ | what you can do is to generate a class that overrides it via .emit and takes a closure |
| 17:42:08 | * | mrordinaire quit () |
| 17:42:15 | Araq_ | I thought about mapping 'method' that operates on a type that is importcpp'ed to a real C++ method so that overriding works |
| 17:43:18 | * | sillesta quit (Ping timeout: 245 seconds) |

| 19:03:51 | Varriount|Busy | dumdum: Nope. |
| 19:04:14 | Varriount|Busy | dumdum: A 'var' type in a procedure means 'pass an implicit pointer to this type' |
| 19:05:38 | Varriount|Busy | 'proc foo(s: var string)' means 'a procedure named foo which takes an implicit pointer to a string object' |

| 19:30:27 | EXetoC | Varriount|Busy: actually, that was specifically about RuneImpl, but the other cases are just for indexing, right? and then it follows the usual pattern |
| 19:30:50 | EXetoC | ekarlso: the documentation for the system module has an example |
| 19:33:28 | ekarlso | EXetoC: so generics approach won't work ? :D |

| 19:35:17 | EXetoC | ekarlso: this approach would involve generics |
| 19:36:02 | ekarlso | EXetoC: yeah but I guess not with a map or so |

| 20:48:27 | dom96 | but I guess it is annoying if you have to handle the errors multiple times |
| 20:48:57 | ekarlso | would be nicer if you could just have your own toplevel error handling proc or smth |
| 20:49:39 | Araq_ | yeah something like system.onRaiseHook ... |

| 20:50:07 | Araq_ | dunno |
| 20:50:38 | Araq_ | I'd wrap it in a template, I think |
| 20:53:36 | dom96 | Wrapping it in a template might not work because of 'halt' |

| 20:55:18 | dom96 | ekarlso: I will add a error handler at some point to jester. |
| 20:55:19 | ekarlso | dom96: 2 inches away from "nimble register" in a folder with a .nimble file .. |
| 20:55:31 | dom96 | bbl |
| 20:55:47 | ekarlso | it registers the package now just the version left |
| 20:55:58 | perturbation | ekarlso: what type of project are you using jester for? (curious) |
| 20:56:10 | ekarlso | perturbation: npm a'la nim |
| 20:56:34 | perturbation | cool |
| 20:57:13 | ekarlso | https://nim-pkg.svcs.io/#/tags/list < example of how it'll be |
| 20:57:19 | ekarlso | release part is missing there though |
| 20:57:38 | perturbation | I've been playing around with using jester for building a JSON REST API with db_sqlite as the data store |
| 20:57:50 | ekarlso | perturbation: that's what this is :p |
| 20:57:58 | ekarlso | getting *fairly* big as well atm :| |
| 20:58:00 | * | skyfex__ quit (Quit: (null)) |
| 20:58:05 | perturbation | oh awesome |
| 20:58:16 | ekarlso | 800+ lines ish atm |
| 20:58:20 | ekarlso | but needs a cleanup soon |
| 21:00:17 | perturbation | one thing I was going to try (after digging a bit into how jester does its macro magic) was adding some sort of middleware for authentication, etc. - is that already a solved problem? |
| 21:00:39 | ekarlso | perturbation: I've added JWT to this stuff |
| 21:00:50 | ekarlso | or at least a basic version of it, still need to add claim checking |
| 21:01:03 | ekarlso | http://github.com/ekarlso/nim-jwt |
| 21:01:43 | ekarlso | perturbation: the packages website uses satellizer for auth with local / github as alternatives |
| 21:02:59 | perturbation | yeah I'm totally stealing^W integrating nim-jwt |
| 21:03:07 | perturbation | you're using angular as the frontend? |
| 21:03:18 | ekarlso | perturbation: ye |
| 21:03:28 | * | sampwing joined #nim |
| 21:03:53 | perturbation | I need to check that out... I've heard it's really nice |
| 21:05:54 | ekarlso | perturbation: meh, one of the dudes behind it just started a new framework hah |
| 21:06:00 | ekarlso | angular in one awy with the scope stuff is messed up |
| 21:07:45 | perturbation | I've heard 2.0 kind of breaks everything... I'm really new to front-end stuff but I started a project in Dart and I love the amount of structure/discoverability that it brings over Javascript |

| 22:22:33 | * | lkg joined #nim |
| 22:23:14 | lkg | my cmd isn't finding the term nim. I installed the binary and through github. What should I do? |
| 22:25:52 | wtw | your nim executable is not in your path, do something like "export PATH=$PATH:/your/nim/path" |
| 22:26:24 | EXetoC | seems like he's on windows |
| 22:26:38 | wtw | ar, right |
| 22:26:40 | wtw | ;) |
| 22:27:01 | lkg | yeah i am |
| 22:27:10 | EXetoC | http://stackoverflow.com/questions/6832496/command-prompt-how-to-add-a-set-path-only-for-that-batch-file-executing |
| 22:27:22 | EXetoC | it can be done temporarily, but locate the binary and try that |
| 22:27:29 | wtw | set PATH=%PATH%;c:\your\nim\path |
| 22:27:43 | lkg | just the nim folder? |
| 22:28:03 | wtw | yep |
| 22:28:29 | * | jasondotstar joined #nim |
| 22:28:30 | wtw | you may also add this to your environment variables if it works, to make it permanent |
| 22:29:49 | * | Synatra joined #nim |
| 22:29:59 | EXetoC | where the binary is located |
| 22:30:09 | Synatra | sup |
| 22:30:14 | lkg | not doing it right. is %PATH% supposed to be something? can you give me an example |
| 22:30:15 | wtw | via "system properties" -> advanced system settings -> advanced -> environment variables -> path |
| 22:30:21 | lkg | ah |
| 22:30:30 | wtw | try echo %PATH% |
| 22:32:01 | EXetoC | lkg: no that's the existing path variable, and so you have that first and then you append a path at the end |
| 22:32:05 | * | keyle joined #nim |
| 22:32:21 | keyle | morning. |
| 22:32:51 | lkg | im not understanding. I added C:\Nim to the PATH variable, which isn't working |
| 22:33:07 | keyle | you want nim\bin probably |
| 22:33:11 | keyle | where the binary resides |
| 22:33:19 | lkg | okay |
| 22:33:58 | lkg | there we go |
| 22:34:00 | wtw | :) |
| 22:34:02 | lkg | thanks |
| 22:34:27 | wtw | now make it permanent :) |
| 22:34:34 | wtw | or did you do that already? |
| 22:34:43 | * | gmpreussner|work quit (Read error: Connection reset by peer) |
| 22:34:45 | lkg | i think so. I added it to the environment var |
| 22:34:51 | wtw | ok :) |
| 22:35:15 | lkg | friendlier than the rust community here XD |
| 22:35:25 | EXetoC | yeah? |
| 22:35:30 | Synatra | Im from the rust community :( |
| 22:35:41 | wtw | me too, more or less, but mostly lurking |
| 22:36:00 | lkg | i find rust pretty busy |
| 22:36:02 | Synatra | we are very friendly |
| 22:36:52 | Synatra | Yeah our IRC can be hectic :I |
| 22:37:01 | lkg | i dont disagree, it's just that i don't see this many ":)" in #rust |
| 22:37:38 | EXetoC | apathic bastards :p |
| 22:37:41 | wtw | hehe |

| 23:04:30 | def- | ah, ll is some dll you're missing? |
| 23:05:13 | def- | googling makes me believe it's something with directx |
| 23:05:29 | Synatra | Question |
| 23:05:38 | Synatra | does Nim have these types of pointers? |
| 23:05:39 | Synatra | http://prntscr.com/5xhiih |
| 23:08:42 | def- | Nim has traced pointers (ref) and untraced pointes (ptr). I would say that's about it |
| 23:08:45 | def- | http://nim-lang.org/manual.html#reference-and-pointer-types |
| 23:09:18 | Synatra | okay |
| 23:09:34 | EXetoC | "lent pointers" is in the roadmap. not sure what it means |
| 23:10:51 | lkg | hm i thought i had the right dlls |
| 23:11:00 | def- | lkg: you have directx 10? |
| 23:11:19 | lkg | im not sure, im trying to use opengl right now |
| 23:11:59 | def- | seems like sdl2 links against ll.dll from directx though |
| 23:17:10 | chroem | So, uh, c2nim depends on 0.10.3, and the latest version is 0.10.2... |
