| 00:08:29 | Araq | what is a 'trySend' ? |
| 00:08:38 | Araq | it's called tryRecv |
| 00:09:10 | Araq | I said "send" does not block, depending on your definition of block. |

| 09:42:55 | FromGitter | <alehander42> yeah , the things I did.. ugly things |
| 09:43:11 | FromGitter | <alehander42> I also had a very weird problem : I couldn't `getType` of NimNode itself |
| 09:43:29 | FromGitter | <alehander42> somehow I only got ref NimNodeObj and this resolved to empty object |
| 09:45:50 | FromGitter | <alehander42> ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=5ae6e5ce1388b2df211295ad] |
| 09:45:56 | FromGitter | <alehander42> @Araq do you know why this happens ^ |
| 09:46:44 | FromGitter | <alehander42> it runs ⏎ ⏎ ```ref[NimNodeObj] ⏎ object``` [https://gitter.im/nim-lang/Nim?at=5ae6e60415c9b031144e6c70] |
| 09:48:46 | Araq | macro call within macro |
| 09:48:52 | Araq | it's the correct behaviour |
| 09:49:10 | Araq | ident"e" is a NimNode |
| 09:49:18 | FromGitter | <alehander42> yes this is exactly what I wanted |
| 09:49:21 | FromGitter | <alehander42> what I mean is |
| 09:49:31 | FromGitter | <alehander42> why couldn't I get the fields of NimNodeObj but I saw |
| 09:49:38 | FromGitter | <alehander42> `NimNode* {.magic: "PNimrodNode".} = ref NimNodeObj` |
| 09:49:42 | FromGitter | <alehander42> in system.nim |
| 09:50:06 | Araq | well it has no fields? |
| 09:51:16 | FromGitter | <alehander42> yeah I was assuming it has, but then I saw it's all getters |
| 09:55:16 | FromGitter | <alehander42> so is there a good way to directly somehow getType of `symbol` . `property` in a macro? |
| 09:55:43 | * | PMunch joined #nim |
| 09:55:47 | FromGitter | <alehander42> (without generating an invocation of a next macro with typed ) |
| 09:56:15 | FromGitter | <mratsim> none :/ or I didn’t find it. |
| 09:57:03 | FromGitter | <mratsim> I think this needs a dedicated section in the macros module |

| 14:23:29 | miran | not mentioned there: we need 0.18.2 / 0.19, to introduce new notNil behaviour of seqs and strings to the stable branch |

| 14:30:57 | * | yglukhov quit (Remote host closed the connection) |
| 14:35:13 | FromGitter | <data-man> It would be great if the Nim developers worked more consolidated. E.g. create more Nim-organizations: NimSystem, NimGraphics, NimDB, NimMath, etc. |
| 14:35:38 | miran | good idea, write it there to have all ideas in one place.... |

| 14:39:20 | FromGitter | <data-man> @miran: Please, do it! I'm ashamed of my English. :) ⏎ @federico3: No. Combine existing projects in the organizations. |
| 14:39:33 | shashlick | so there's been 3 attempts to my knowledge for a nim installer - niminst, finish and choosenim |
| 14:39:43 | miran | data-man: your english is as good as mine ;) |

| 14:41:10 | miran | federico3: i would say - more focused development (as i just mentioned in my reddit comment) - divide people into groups, so they can focus on one part of nim language and work on it |
| 14:42:21 | miran | currently it feels to me the development is like a bit of this, a bit of that, a bit of long term goals, a bit of something urgent, a bit of something else, etc |
| 14:43:40 | federico3 | miran: if you are referring to core stuff (compiler, stdib, tooling) than yes, having roles/owners/teams could really help |
| 14:45:15 | miran | i'm trying to expand on what data-man has mentioned |
| 14:46:33 | miran | this can be, of course, postponed after v1.0 is out. having said that - we probably need at some point 'feature freeze' - no more new features for 1.0, and work only on bugfixes |
| 14:46:54 | FromGitter | <data-man> @federico3: Yes, to encourage collaborative maintenance. |

| 15:32:41 | shashlick | Nim windows installer related: https://gist.github.com/genotrance/534e3a49138eec2894299881f5e60105 <== feedback appreciated, cc @dom96 @araq |
| 15:33:37 | PMunch | shashlick, I tried quit(100) but it quits with error code 1 |
| 15:33:43 | PMunch | No matter what number I put |
| 15:34:24 | PMunch | Same if I try to use an error message |
| 15:35:14 | shashlick | ideally choosenim can be enhanced to do most of the heavy lifting and GUI is just a front-end to choosenim, also leverage code from finish and niminst where appropriate |
| 15:36:13 | livcd | shashlick: that's nice and all but..not long ago people had been advised to stick to Nim devel |
| 15:36:18 | livcd | because of whatever bugs |
| 15:36:52 | miran | one more reason to do more frequent stable versions! |
| 15:37:00 | shashlick | well, we need to move away from that based on https://github.com/nim-lang/Nim/issues/7527 |
| 15:37:46 | shashlick | a release is a release that people should stick to for a project and only upgrade if something blocks them |
| 15:38:31 | livcd | well users that just want to poke around want "use whatever works not atm / use whatever everyone uses atm" |

| 15:39:14 | shashlick | that's why I have added the ability to live on devel |
| 15:39:26 | shashlick | in fact, it should allow single click updates as well |
| 15:39:36 | dom96 | shashlick: yes, all we need is a thin GUI wizard on top of choosenim IMO |
| 15:40:03 | dom96 | I've thought about generalizing that to all CLI programs and creating a project that allows to easily create an installer for CLIs |
| 15:40:34 | * | rauss joined #nim |
| 15:41:01 | FromGitter | <data-man> @PMunch: I assume, that a mistake on your side because the quit is heavily used in tests. |
| 15:42:01 | shashlick | dom96: well, choosenim still needs to allow binary install, git pull capable devel install, arch detection, etc to pull this off |
| 15:42:17 | shashlick | but I agree it is the right base |

| 15:48:05 | shashlick | dom96: I'm not sure a generalized GUI will work for this |
| 15:48:18 | shashlick | especially installing compilers, git, etc. seamlessly |
| 15:48:31 | dom96 | why? |
| 15:49:10 | dom96 | There might need to be some hooks to specify progress or check boxes for options |
| 15:50:00 | shashlick | well, for example, assuming we add code to choosenim to detect installer presence, it needs to inform the GUI on the results |
| 15:50:13 | shashlick | for that the CLI => GUI will need to scrape the output kind of stuff |
| 15:50:22 | shashlick | or CLIs will need to adhere to some scheme |
| 15:50:30 | shashlick | which means the CLIs need to change to work with the GUI |
| 15:50:50 | FromGitter | <data-man> For Windows users we should recommend to use MSYS2 :) |
| 15:50:50 | shashlick | it's a conversation in my mind, not just calling the CLI with a bunch of predetermined flags |
| 15:51:31 | shashlick | data-man: i'm saying allow install of vc++ or clang as well so user has choice |
| 15:51:41 | dom96 | Sure, CLI will need to adhere to a certain scheme. Most CLIs already do. |
| 15:52:06 | dom96 | Like I said, there will need to be some customisability. But that can be done using simple checkboxes (for a first version at least) |
| 15:52:13 | dom96 | I'm just curious how far this concept can go |
| 15:52:23 | dom96 | If you don't want to try it then no worries |
| 15:52:51 | shashlick | well, i'm always open to generic methods |
| 15:53:12 | shashlick | but do you think we can handle the "Figure out C/C++ compiler" section with this method? |
| 15:54:51 | dom96 | We can also support dropdowns |
| 15:55:05 | dom96 | The idea is to map UI elements to simple CLI flags |
| 15:55:20 | shashlick | PMunch: I just tried on Windows / devel and quit(5) => ERRORLEVEL = 5 |
| 15:55:25 | dom96 | so you can run `choosenim --cc:clang stable` |
| 15:55:39 | livcd | why not to have the ...by default support for mingw and the resp optional where the user points the installer to the right paths for other compilers ? |
| 15:55:45 | dom96 | or rather so that the installer can run this |
| 15:56:14 | shashlick | livcd: ya we can go step by step, not have to support everything in one shot |
| 15:56:15 | dom96 | yeah, to be honest supporting installation of other compilers is something that's a far off goal for choosenim IMO |
| 15:56:31 | shashlick | but this is purely aspirational at this point |
| 15:56:33 | dom96 | It probably pays to have as few variables as possible too |
| 15:57:23 | * | jrbrt joined #nim |
| 15:57:27 | * | yglukhov joined #nim |
| 15:58:36 | shashlick | dom96: so if clang is already installed then the GUI shouldn't show that option at all - so we'd need some way for GUI <=> CLI to have a conversation and intelligently show the right things on the GUI |
| 15:59:17 | shashlick | so CLI would need to have a --detect flag or something that gives the GUI all the state info it needs to show the right info |
| 15:59:36 | shashlick | plus any dependency info where if A is selected, then B is greyed out and things like that |
| 15:59:58 | dom96 | Meh, I think the abstraction breaks a bit for that case. |
| 15:59:59 | shashlick | without this, it won't have a refined experience typical of installers |
| 16:00:05 | dom96 | But my idea is to keep things simple |
| 16:01:45 | shashlick | ok considering the base is choosenim, what features do we need in it to meet this requirement list? I added some stuff to the gist, please see if it is complete |
| 16:02:03 | * | yglukhov quit (Ping timeout: 256 seconds) |
| 16:03:17 | dom96 | choosenim is missing many things from your list |
| 16:03:23 | dom96 | sorry, I don't have time to go through it all now |
| 16:03:58 | shashlick | what's one good choosenim feature you'd like to see soon? I could take a look |

| 16:23:05 | FromGitter | <Bennyelg> I got it, but why `Don't use fmt with SqlQuery` |

| 16:26:49 | * | Ven`` quit (Quit: My MacBook has gone to sleep. ZZZzzz…) |
| 16:28:01 | FromGitter | <nigredo-tori> @Bennyelg , `SqlQuery` is a thin wrapper over `string` for better typing. AFAIK, Nim does not have a proper SQL interpolation primitive. |
| 16:28:58 | FromGitter | <nigredo-tori> And even if `SqlQuery` did something like that, any interpolation in your example would have been done by `fmt`, which knows nothing about SQL. |
| 16:29:21 | FromGitter | <Bennyelg> got it Thanks :) |

| 20:39:54 | CodeVance | a crown is a symbol |

| 21:04:39 | shashlick | mecho.txt is the input - basically the output of grep proc math.nim |
| 21:04:45 | dom96 | also there is no way you could make that look cute lol |
| 21:05:14 | Araq | yglukhov_, just create the AST but ensure every node has type |
| 21:05:25 | shashlick | output I get from mecho.nim is test.nims - i've commented out the procs that aren't yet present in nimscript and so don't work |

| 21:06:25 | yglukhov_ | Araq: how do i create a proper array type? |
| 21:06:32 | dom96 | shashlick: I guess you want to parse those proc types? |
| 21:06:47 | yglukhov_ | array[N, int16] |
| 21:06:50 | shashlick | ya a cleaner way to do this - i wanted to have mechoall() call another macro mecho() with pname as a param but not able to pass it in as a string |
| 21:06:58 | dom96 | Why not just use parseExpr() on each line? |
| 21:07:06 | dom96 | You might need to prefix those with 'proc' for that to work |
| 21:07:11 | dom96 | well, or parseStmt |
| 21:07:31 | Araq | yglukhov_, will probably be messy... check the helpers in semdata.nim |
| 21:07:38 | shashlick | I'm using parseStmt() but if I get pname from the file in mechoall(), I cannot pass it into another macro since it won't be known at compile time as a string |

| 21:13:30 | shashlick | dom96: so if I have `macro mecho(pname, lval, hval: string): untyped =` then inside mecho, pname, lval and hval are treated as NimNodes |
| 21:14:01 | shashlick | Error: type mismatch: got <string, array[0..2, NimNode]> when I try "$# $# $#" % [pname, lval, hval] |
| 21:16:12 | dom96 | yeah, but they are string literal nodes, so you can get the string via strVal IIRC |
| 21:16:21 | dom96 | This definitely needs better documentation |
| 21:16:35 | dom96 | Alternatively you can also create a {.compileTime.} proc |
| 21:16:36 | Araq | these words have lost all meaning by now |
| 21:16:37 | shashlick | if I use pname.strVal(), echo pname gives you "pname" |
| 21:17:22 | yglukhov_ | which code is more efficient? "x == -1" or "x < 0"? :) |
| 21:17:50 | Araq | so what's the compiler developer gonna do? special case every error message into thousands of what-ifs, trying to guess what the developer meant? it's Nim, it has a macro system, you need to read how it works. |
| 21:18:09 | Araq | a NimNode is not a string. |
| 21:18:25 | Araq | how much more information do you think the compiler can give you? |
| 21:18:53 | shashlick | well I understand that the contents of the file are not known at compile time |
| 21:19:06 | shashlick | so using parseStmt, I could use it in the macro |
| 21:19:36 | shashlick | but I just want to understand if it is possible to pass the string to another macro and have it known |
| 21:22:21 | Araq | sure, pass it. |

| 21:28:30 | dom96 | We also need a tutorial for macros |
| 21:28:49 | * | jjido quit (Client Quit) |
| 21:28:51 | dom96 | shashlick: pname.strVal() gives you "pname"? |
| 21:31:03 | FromGitter | <mratsim> @yglukhov compare to 0 |
| 21:32:09 | FromGitter | <mratsim> comparing to zero is more efficient than anything else you can summon because you don’t need to LEA or MOV the value in the register |
| 21:32:45 | shashlick | Yes it gives the name of the variable in the parent macro |
| 21:33:03 | FromGitter | <mratsim> but unless you call that 10 millions times per second I don’t think you will have any perf issue |
