11:20:35FromGitter<Bennyelg> how I can implement it via nim directly

12:23:38Araqyay, more functional languages
12:23:51zacharycarter[m]yeah - that was my first thought
12:24:26zacharycarter[m]although it's written in OCaml so surprise
12:24:30zacharycarter[m]no surprise*
12:24:50zacharycarter[m]seems like functional OCaml is all the rage with hipster web devs these days
12:25:50zacharycarter[m]if I could figure out how to handle gc refing closures passed to add and removeevent handlers - I could make progress on my nim wasm web project
12:25:52zacharycarter[m]but I have no idea what to do there
12:26:24Araqthe 'w' part of 'wasm' is a lie ;-)
12:26:58FromGitter<Bennyelg> Question; I want to use cligen but I want for some argument to be typed without showing the content (specially for passwords)
12:27:02zacharycarter[m]isn't wasm basically an open flash?
12:27:27zacharycarter[m]or java applet?
12:27:33FromGitter<Bennyelg> eg: --use_tags=true --username=timor --password=****
12:27:51Araqas they are still figuring out how to access the web technologies with their everything-is-now-an-array-of-words-again ideas
12:29:10AraqBennyelg, that's not how things work, you need to read passwords from stdin, not from the command line arguments
12:29:55FromGitter<Bennyelg> yeah you are right

13:05:16FromGitter<gogolxdong> we added a favicon.ico , and it became so.
13:09:18dom96gogolxdong: did you upgrade Jester?

13:12:13FromGitter<gogolxdong> nimble install jester and overwrite?
13:12:21FromGitter<gogolxdong> I used so.
13:12:34FromGitter<gogolxdong> it's the latest.
13:12:56dom96I'm asking if you did this
13:13:03dom96Because that's likely what caused your program to break
13:13:37livcdhmm i guess we do not
13:15:49FromGitter<gogolxdong> @dom96, it's the latest, it used to work serveral hours ago.

13:16:40dom96Did you restart it during those hours?
13:16:45dom96Did you change anything?
13:16:47dom96Did you recompile it?
13:19:24FromGitter<gogolxdong> added a favicon.ico , didn't change server file.
13:21:11dom96So does removing fix it?
13:22:33FromGitter<gogolxdong> this is the strange thing , we checkout to previous commit which has no favicon.ico , but still the same.
13:24:01dom96Try downgrading to Jester 0.2.1
13:24:10dom96`nimble install [email protected]`
13:25:29FromGitter<gogolxdong> doesn't work.
13:27:11dom96Recompiled and restarted?
13:28:52FromGitter<gogolxdong> sure.
13:29:18dom96Then why is this showing 0.4.0? http://bafang.cloud/index.html
13:29:48FromGitter<gogolxdong> it's the DNS cache
13:30:11dom96What does DNS have to do with this?
13:30:19dom96Have you update the IP that your domain points at?
13:30:23dom96*updated
13:31:42FromGitter<gogolxdong> I tried ip address, it's 0.4.0 , but I have installed using nimble install [email protected]
13:32:46FromGitter<gogolxdong> 1) 251.109.118
13:34:09FromGitter<gogolxdong> how to check which jester version compiled?
13:34:52FromGitter<gogolxdong> there is jester-0.2.1 and jester-0.4.0 under ~/.nimble/pkgs/
13:38:45FromGitter<generative99> Is there no alias for bitwise and/or just for readability?
13:38:57FromGitter<generative99> to differentiate from logical and/or
13:39:36FromGitter<gogolxdong> there is too much compile error of jester-0.2.1
13:43:28dom96Does your program have a .nimble file?
13:43:41dom96if so you can add `requires "jester 0.2.1"` in there
13:43:49dom96then running `nimble c program.nim` will use jester 0.2.1
13:44:00dom96`nim c` will use whatever latest version you have installed
13:44:09dom96so you can also remove 0.4.1: nimble remove [email protected]
13:44:16dom96or sorry, 0.4.0

14:14:10dom96771 responses on our survey :)
14:14:14FromGitter<mratsim> unless it’s an April Fools? Current Status (last updated April 1, 2018)
14:14:35Araq"A compiler which compiles C++ to C does full syntax and semantic checking on the program, and just happens to use C code as a way of generating object code. Such a compiler is not merely some kind of fancy macro processor. (And please don’t email me claiming these are preprocessors — they are not — they are full compilers.)"
14:14:38FromGitter<mratsim> but iirc Mercurial mentionned their Python slowness issue several times on HN
14:14:48Araqreplace "Preprocessor" with "transpiler" :-)
14:17:19*endragor quit (Ping timeout: 265 seconds)
14:17:38FromDiscord<awr> wrt what people normally think of when they think of transpilers (not nim), is it expected that the transpiled contents be human-readable?
14:17:44*brainproxy quit (Ping timeout: 260 seconds)
14:18:04FromDiscord<awr> the only transpiled language i can think of off the top of my head is coffeescript
14:18:07Araqno, that would be a source to source translator
14:19:11FromDiscord<awr> i thought that was synonymous with transpilation
14:19:16FromDiscord<awr> wiki seems to think so
14:19:20FromDiscord<awr> https://en.wikipedia.org/wiki/Source-to-source_compiler
14:20:50Araqeverybody, including wiki, has problems with words that make no sense.
14:25:53*brainproxy joined #nim
14:27:00FromDiscord<awr> the terminology what is and isn't a transpiler is a little confusing
14:27:45*cryptocat1094 joined #nim
14:28:24Araqyes, but now I know, a transpiler is a preprocessor.
14:28:41Araqit's just that word fell out of fashion.
14:28:56FromDiscord<awr> on one end you have stuff like coffeescript that act as a preprocessor + some magic and on the other end you have stuff like nim and emscripten whose output language happens to be originally intended for human reading and writing but is used more like an IR language and a portability mechanism if anything
14:29:13FromGitter<gogolxdong> migrated to Go web framework, it works.
14:31:45leorizeAnyone have any idea how to debug tcompilerapi test?
14:32:05Araqleorize, what about it? it should be green
14:32:11leorizeI can't compile the file without using testament
14:32:22dom96gogolxdong: did you try what I suggested?
14:32:38leorizeAraq: I'm porting Nim to Haiku so I'm trying to fix tests that aren't working
14:32:59leorizegot "cannot find Nim's standard library" :/
14:35:52Araqah :-)
14:40:19FromGitter<gogolxdong> until found 0.2.1 has many compile error.
14:40:58FromGitter<gogolxdong> didn't have enough time,will check later.
15:03:37leorizeAraq: is it possible to make testament build a binary with debuginfo?
15:04:26Araqsure but if 'nim c -r tests/tcompilerapi' fails, you can as well just add debug info there. but
15:05:27stefanos82the question is leorize, which GCC are you pointing at your nim? Haiku comes with 2 separate versions; a fork of GCC2 for their kernel build and GCC7 for the rest of the stuff
15:05:40Araqthe code to read is in compiler/nimeval.nim, proc findNimStdLib
15:05:57Araqprobably 'findExe' is wrong on Haiku
15:06:11leorizeAraq: using nim c -r got "cannot open file: std/os"
15:06:28leorizeand somehow testament magically able to build it :/
15:06:37leorizestefanos82: I'm running gcc7
15:06:45stefanos82very nice
15:10:16leorizeAraq: got the test passed :D
15:10:32leorizelooks like the test was designed with the assumption that nim is installed?
15:11:08leorizeI added the folder w nim executable to PATH and it worked :)
15:13:20Araqwell 'findExe' uses your PATH
15:13:34Araqhow else could it find it, I mean it's an example program
15:13:52Araqyou can write your own findNimStdLib()
15:14:52leorizeI thought the test was supposed to run before Nim is installed?
15:15:28*nsf quit (Quit: WeeChat 2.2)
15:15:34Araqreally? do we want people to wait for one hour before installation can start?
15:15:42leorizeit's a small fix to the build script anw, so it's all fine :P
15:15:59Araqwell PRs are always welcome
15:16:32leorizeour build system isolate the build in chroot, so the compiler is not installed yet at that point
15:16:53leorizeit's mainly for regression testing, not something for the user to wait
15:17:24leorizethanks to Nim I found a few bugs in Haiku :D
15:23:31FromGitter<Varriount> leorize: Like?

16:54:44FromGitter<Quelklef> no
16:55:01bozaloshtshah then explain more please what is meant by "a macro" here
16:55:07FromGitter<Quelklef> Write a macro that adds the cov pramga to each proc decl
16:55:19bozaloshtshoh like sed
16:55:24FromGitter<Quelklef> ..?
16:55:40bozaloshtshyou mean literally modify the code with regexp to add the pragma?
16:55:45FromGitter<Quelklef> No
16:55:47FromGitter<Quelklef> Uh
16:55:51FromGitter<Quelklef> Nim's macros are really powerful
16:56:08FromGitter<Quelklef> And work on a level more abstract than sourcecode
16:56:18bozaloshtshright, but how am I supposed to make a macro that modifies all procs
16:56:40FromGitter<Quelklef> Well you'd write a macro that'd take in a `stmtList` and modify all procs in that
16:56:45FromGitter<Quelklef> and then in your file
16:56:49FromGitter<Quelklef> you'd do
16:57:14FromGitter<Quelklef> ```# to this ⏎ import X ⏎ import myCovWrapper ⏎ myCovWrapper: ⏎ code``` [https://gitter.im/nim-lang/Nim?at=5b6094ea17c942036b87c82e]
16:57:54bozaloshtshactually I'm pretty sure the cov pragma is also a macro
16:57:58bozaloshtshso I could just do cov: my code
16:58:05FromGitter<Quelklef> No
16:58:10FromGitter<Quelklef> Well, maybe. Probably not
16:58:20bozaloshtshpretty sure that's how nim-defined pragmas work
16:58:23FromGitter<Quelklef> `cov` probably is a macro, but it probably works on proc definitons
16:58:27FromGitter<Quelklef> no, it's not
16:58:45FromGitter<Quelklef> `proc X() {.someMacro.} =` gets the singular proc definition
16:58:45bozaloshtshmacro: proc def is not the same as proc def {.macro.} ?
16:58:53bozaloshtshahh so can't do multiple procs in one shot
16:58:56FromGitter<Quelklef> right
16:59:36bozaloshtshin any case, this might let me get coverage without messing with my source: https://hookrace.net/blog/nim-code-coverage/
16:59:52bozaloshtshthanks
17:00:00FromGitter<Quelklef> Looks like it
17:00:30FromGitter<Quelklef> Sure. By the way, take a look at Nim's macro system. It's really nice and absolutely worth learning
17:02:29bozaloshtshI've read a bunch of macro code modifying the AST but honestly templates have been enough for me so far

17:31:11xomachine[m]I might be mistaken, but is not a 'push' pragma made exactly for applying another pragmas to multiple entities? @bozaloshtsh

18:50:35FromGitter<krux02> it is a function pointer returning int and accepting a void *
18:50:49FromGitter<krux02> (pointer) -> int
18:53:53FromGitter<Varriount> @kayabaNerve College
18:56:02FromGitter<xmonader> @krux02 thanks it worked
18:59:18FromGitter<kayabaNerve> Congrats
18:59:55FromGitter<kayabaNerve> proc myProc(a: pointer): ptr cint {...}
19:08:18FromGitter<krux02> @kayabaNerve the function returns a normal cint not a ptr to cint. The * is bound to fn making it a function pointer.
19:08:52FromGitter<kayabaNerve> Oh; misread it.
19:08:58FromGitter<kayabaNerve> Sorry.
19:09:17FromGitter<kayabaNerve> Nim doesn't have function pointers; just functions.
19:09:51FromGitter<kayabaNerve> (proc (a: pointer): cint)
19:09:53FromGitter<kayabaNerve> ?
19:10:31FromGitter<kayabaNerve> ptr proc (a: pointer): cint maybe... no idea. Would have to try a few. Hopefully this helps enough to get you there. Sorry.

19:18:34Araq(proc (a: pointer): cint) is it.
19:18:44Araqechoing without newline, stdout.write
19:19:28Araqor stderr.write, you can ponder about this question forever, sometimes a choice is just a design bug
19:19:54FromGitter<Bennyelg> Idid something like write(stdout, "message")

20:45:53FromGitter<imdaveho> hi, I searched google and the forums, but couldnt find a good reference around how to best code/what needs to be considered with writing something with--gc:none. Since nim primitives assume the gc, is there anything out there that documents how to best manually manage memory in that case? for all user specified objects on the heap, that's a bit more clear...
