| 01:27:14 | FromGitter | <kayabaNerve> Because I'm struggling to call it. I want something close to the original, but I'll take other ways... |
| 01:27:31 | FromGitter | <kayabaNerve> And there's a reason I don't just do myProc(times, hex) |

| 01:46:40 | FromGitter | <rayman22201> @kayabaNerve https://nim-lang.org/docs/macros.html#calls-expressions-array-access-operator |
| 01:46:46 | FromGitter | <rayman22201> love the macro |
| 01:47:05 | FromGitter | <rayman22201> though I agree, super weird thing to do lol |
| 01:47:12 | FromGitter | <Quelklef> He said he wants a 'working ^ decl' though so I think macros can't be used? |
| 01:47:18 | FromGitter | <Quelklef> should still be possible I think |
| 01:48:00 | FromGitter | <Quelklef> is ``proc `^`(f: proc(hex: string): string, times: int): proc(hex: string): string`` also ok? Because that should be possible and fit the given syntax |
| 01:48:13 | FromGitter | <Quelklef> not quite, you'd need to do `(proc^4)(string)` but |
| 01:49:32 | FromGitter | <Quelklef> yeah wait `proc^4(data)` is going to be parsed as `` `^`(proc, 4(data))`` I think, so what you're asking isn't quite possible |
| 01:49:38 | FromGitter | <Quelklef> wait, maybe with term rewriting macros? |
| 01:52:04 | CodeVance | not possible with quote do |
| 01:52:11 | CodeVance | use something else |
| 01:52:15 | CodeVance | "^".ident |
| 01:52:32 | FromGitter | <Quelklef> ? |
| 01:56:35 | CodeVance | nvm |
| 01:57:17 | FromGitter | <Quelklef> I think `3(4)` is a parsing error, so this isn't possible :( |
| 01:57:35 | FromGitter | <Quelklef> `Error: in expression '3(4)': identifier expected, but found '3'` |
| 01:57:44 | FromGitter | <Quelklef> Disappointing, I think it'd be possible otherwise |

| 04:25:04 | FromGitter | <Varriount> I need a template that will repeat a given block of code X number of times, passing in a list of expressions and an identifier to determine how many times the block should repeat. |
| 04:26:18 | FromGitter | <Varriount> I'm guessing the syntax would probably be something like: ⏎ ⏎ ```repeatBlock([a,b, c], ident): ⏎ ident * ident``` [https://gitter.im/nim-lang/Nim?at=5b3afaea3572e970c170dacc] |

| 04:32:25 | FromGitter | <Quelklef> I can try but I dont' quite understand what you're wanting |
| 04:33:04 | FromGitter | <Quelklef> Is it like ⏎ ⏎ ```repeatBlock([2, 3, 4], x): ⏎ echo(x)``` ⏎ ⏎ echoes 2, then 3, then 4? [https://gitter.im/nim-lang/Nim?at=5b3afc7f60c3870783589b9b] |

| 04:36:28 | FromGitter | <Quelklef> Sorry, I'm doing 2 things at once right now as well |
| 04:37:08 | FromGitter | <Varriount> It's not really important, I was really just wondering if someone had some handy-dandy function ready. |
| 04:37:59 | FromGitter | <Quelklef> i mean I bet it's possible |
| 04:38:08 | FromGitter | <Quelklef> you could learn macros and make it yourself too! |

| 05:04:22 | FromGitter | <kayabaNerve> @Quelklef I'd still have to do the substring wrap which is my man issue. |

| 07:04:09 | FromGitter | <Quelklef> @mratsim No yes I just mean that parsing a function call isn't `expr(expr)`, it's something else |
| 07:04:52 | FromGitter | <Quelklef> seemingly along the lines of `(identifier | '(' expr ')') '(' expr ')'` |
| 07:05:13 | FromGitter | <Quelklef> and I feel like that's a slight downfall |

| 08:19:58 | Tanger | Hey guys, I'm trying to test the stdin reading of an app by redirecting stdin to a file in my tests. Problem is I have a quit call in there, which quits out of the actual unit tests. I was considering replacing the quit with a return if it's running a test, but I was curious to see if anybody had a more succinct way to achieve this? |
| 08:35:21 | FromGitter | <narimiran> hmmm, this is strange. i'm doing some numerical calculation and exporting results (floats) to .csv. |
| 08:35:46 | FromGitter | <narimiran> at one point a floating number is wrongly converted to the scientific notation! |
| 08:36:11 | FromGitter | <narimiran> i get `9.775367418133826e-0` instead of `9.775367418133826e-1` (9.77 vs 0.977) |
| 08:42:08 | FromGitter | <narimiran> sorry, the correct value is -0.0977536 (minus, and one more decimal zero) |

| 08:49:13 | FromGitter | <narimiran> this is by using the `&` for string formatting, nim stable (0.18.0) |
| 08:53:13 | FromGitter | <narimiran> the same thing in nim devel |

| 11:26:25 | FromGitter | <mratsim> great |
| 11:26:49 | FromGitter | <mratsim> ah it’s expression not statement |
| 11:27:42 | FromGitter | <mratsim> this is similar to C assignment that also returns the value of the expression: `while (value := read_next_item()) is not None:` |
| 11:29:11 | FromGitter | <mratsim> this is tricky though: https://www.python.org/dev/peps/pep-0572/#lowering-operator-precedence |

| 13:04:01 | Araq | so either we can produce foo.cpp.obj or have more subdirs in nimcache/ |
| 13:04:10 | dom96 | yeah, seems like a simple solution |
| 13:04:27 | Araq | but it's also annoying me that nimcache is relative to the current project |
| 13:04:49 | Araq | and not in some /tmp or $home/nimcache |
| 13:04:50 | FromGitter | <narimiran> btw, what's the simplest solution for (one-time) donation to nim? |
| 13:05:26 | dom96 | narimiran: not sure which is simplest, but there are plenty of options: paypal, bountysource, opencollective, bitcoin |
| 13:05:32 | dom96 | All support one-time donations |
| 13:05:48 | dom96 | https://nim-lang.org/donate.html |
| 13:06:38 | FromGitter | <narimiran> since i don't have an account on any of them, i'll try to see what is the simplest for me + the most money for you :) |
| 13:06:55 | Araq | paypal's fees are pretty bad. |
| 13:07:05 | dom96 | every service has fees sadly |
| 13:07:11 | dom96 | bountysource has like 10% |
| 13:07:21 | dom96 | which is far worse than paypal AFAIK |
| 13:07:24 | skrylar | money handling is annoying; you probably want to put up with the fees |
| 13:07:53 | skrylar | (theres also librepay and ko-fi, but well, fees are not avoidable with money. turns out money engineers are good at grubbing) |
| 13:08:24 | dom96 | I also want us to set up a patreon (for Nim and for ourselves) |
| 13:08:31 | dom96 | I wonder what their fees are like |
| 13:09:13 | FromGitter | <narimiran> i guess i should be getting some money in about two-weeks time. hopefully by then i/we will figure out what is the best way to donate |
| 13:09:22 | skrylar | the fees for all of those things is less than Apple/Valve's take |
| 13:09:33 | skrylar | usually less than 30% |
| 13:09:45 | skrylar | but the government will take what patreon doesn't :) |
| 13:10:48 | dom96 | hehe so true |
| 13:11:04 | Araq | esp in Germany, the king of taxes :-( |
| 13:11:14 | * | endragor quit (Remote host closed the connection) |
| 13:11:25 | FromGitter | <narimiran> Araq: isn't your VAT something like 19%? |
| 13:11:45 | FromGitter | <narimiran> because here in Croatia we have nice and round 25%!! |
| 13:11:48 | dom96 | Araq: Not for long. Brexit will make tax rises unavoidable in the UK soon enough |
| 13:13:19 | Araq | narimiran, VAT is 19%, yes. and all around pre-tax vs net is 50% off |
| 13:14:07 | FromGitter | <kaushalmodi> General curiosity: How is the donation used? What part goes to hosting, etc. |
| 13:14:36 | Araq | earn 3000€ officially and live with 1500€ |
| 13:15:13 | FromGitter | <narimiran> same here with pre-tax vs net. the only difference is that what remains after the taxes is here something like 700€ |
| 13:15:45 | Araq | croatia, huh? never was there :-) |
| 13:15:52 | FromGitter | <narimiran> and no, the cost of living is not 2-3x smaller! |
| 13:15:57 | * | ieatnerds joined #nim |
| 13:16:10 | dom96 | kaushalmodi: Digital ocean actually covers our hosting for free. The most recent use of our donations was for the forum. |
| 13:16:35 | FromGitter | <narimiran> croatia - great for holidays (or so the turists think), okayish for living here :) |
| 13:16:47 | Araq | yeah and we have something big (TM) in the works |
| 13:16:55 | dom96 | indeed |
| 13:17:01 | Yardanico | hmmm |
| 13:17:01 | FromGitter | <narimiran> v1.0 or GTFO!!! :D |
| 13:17:21 | Yardanico | ( ͡°( ͡° ͜ʖ( ͡° ͜ʖ ͡°)ʖ ͡°) ͡°) some secret development |
| 13:17:51 | FromGitter | <Vindaar> now I'm curious :P |
| 13:17:56 | nasusiro | Araq: to be honest with you I was thinking as well about nimcache last night. Go figure! |
| 13:18:15 | Araq | narimiran: v1.0 plan is out |
| 13:18:20 | dom96 | nimcache would indeed be better in /tmp/ |
| 13:18:32 | dom96 | It's amazing where a nimcache dir sometimes shows up |
| 13:18:41 | Araq | what do we do with the binaries? |
| 13:18:49 | dom96 | Pretty sure there is a bug in there somewhere that makes it appear in the wrong place |
| 13:18:56 | Araq | I would put them in nimcache too, esp when '-r' is used |
| 13:19:06 | dom96 | no, binaries are different |
| 13:19:26 | nasusiro | dom96: you know what I was thinking about nimcache last night? Replacing it with SQLite database and cache every project in a central database. |
| 13:19:32 | FromGitter | <narimiran> but binaries "somewhere else" would be nice to simplify .gitignore |
| 13:19:43 | Araq | for production I usually use -o:bin/stuff.exe |
| 13:19:51 | Araq | and else I don't care where it ends up |
| 13:20:00 | FromGitter | <kaushalmodi> About nimcache, if you put it in /tmp, please set it in /tmp/$USER/. I have ended up in scenarios where multiple users try to write other user's /tmp dir |
| 13:20:25 | Araq | yeah /tmp is pretty bad. it doesn't even exist on Android. |
| 13:20:46 | nasusiro | Araq: last night I asked whether it's possible to use -o:bin/foo or --out:... in a nimscript. I hate typing -o:bin/foo all the time, whereas --threads:on can be placed in my nimscript and work as expected. |
| 13:20:47 | skrylar | store them in /dev/null, the most efficient of compressants |
| 13:21:16 | skrylar | nasusiro, you could always use a makefile :^) |
| 13:21:27 | Araq | /dev/null doesn't exist on BananajoeUnix though |
| 13:21:35 | nasusiro | skrylar: I don't use makefile; I prefer using meson |
| 13:22:01 | dom96 | Yeah, to be honest saving in /tmp as issues of its own |
| 13:22:05 | Araq | nasusiro, switch("out", "bla") in NimScript should do the job |
| 13:22:06 | dom96 | *has |
| 13:22:19 | skrylar | i like plan9's mk, but requires a lot of crap to be installed. meanwhile, a makefile can have a phony target that just kicks off your project's chosen build scripts |
| 13:22:22 | nasusiro | Araq: what's out and what's bla? |
| 13:22:54 | Yardanico | nasusiro, out is a compiler option and "bla" is a "out" argument |
| 13:23:04 | Yardanico | --out:bla is the same as switch("out", "bla") |
| 13:23:22 | nasusiro | that's more like it, a cleaner explanation that makes sense now lol |
| 13:23:24 | nasusiro | thank you |
| 13:24:02 | FromGitter | <narimiran> so what to put in nim.cfg so all my binaries in a project are in `bin/` subdirectory? |
| 13:25:05 | skrylar | i was reading assembly related stuff earlier (linear scan register allocation; apparently linear scan and/or binpacking are claimed by the whitepaper to be 99% as performnant as graph colored) about how small a compiler can actually be :ponder: |
| 13:25:43 | nasusiro | Araq: what do you think about the SQLite caching suggestion in place of nimcache? |
| 13:26:00 | Araq | narimiran: heh, seems impossible as --out doesn't deal with directories but with filenames |
| 13:26:30 | Araq | nasusiro, we do this for --incremental:on but the C code needs to stay in .c files |
| 13:26:39 | Araq | else I cannot run a C compiler over them ;-) |
| 13:27:13 | nasusiro | I'm sure I have seen a use of it before |
| 13:27:22 | nasusiro | when I find my original resource, I will share it with you |
| 13:27:25 | nasusiro | it's very useful |
| 13:27:30 | Araq | switch("out", "bin/$projectName") |
| 13:28:01 | Araq | don't remember what $variables we support though... |

| 13:28:33 | FromGitter | <mratsim> can’t you just use Stripe or Mangopay for donations. 1.4 and 1.8% fees on European credit card. (And Stripe is 2.9% on American credit card) |

| 13:29:06 | * | endragor joined #nim |
| 13:29:35 | FromGitter | <mratsim> issue with stripe is the different fees for EU vs US (1.4 vs 2.9) while Mangopay is a flat 1.8% |
| 13:29:51 | FromGitter | <mratsim> but MangoPay doesn’t accept American Express iirc |
| 13:30:29 | skrylar | have actually had to start researching this problem (money platforms) |
| 13:30:45 | skrylar | patreon is the easiest but a lot of people don't like them and/or they don't handle single payments well |
| 13:31:05 | skrylar | coalescing benefits from multiple payment platforms seems an annoying task to solve at some point |
| 13:32:04 | dom96 | There is a project which provides a web page for all these services but I can't remember its name |
| 13:33:24 | skrylar | well the harriness comes with if you are doing a benefits package patreon style |
| 13:33:40 | FromGitter | <mratsim> otherwise non-profits in France can use this, no commission whatsoever, but France non-profits only: https://www.helloasso.com/ |
| 13:33:47 | Araq | nasusiro, https://github.com/nim-lang/Nim/issues/7874 feel free to comment |
| 13:34:09 | skrylar | you're expected culturally to make news posts through them (and their clones, if doing simultaneous site runs), and sometimes people get badges or whatever |
| 13:34:14 | nasusiro | thank you Araq, I will read the comments and let you know ;) |
| 13:34:39 | skrylar | mratsim: ko-fi doesn't take a cut (but the underlying processors do) and anyone can use it |
| 13:36:24 | FromGitter | <mratsim> interesting |
| 13:36:57 | FromGitter | <mratsim> ugh, it uses Paypal |

| 13:39:17 | nasusiro | Araq: for GCC there is a caching suggestion if you haven't tried it already; it's called ccache https://ccache.samba.org/ |
| 13:41:41 | FromGitter | <mratsim> ccache is GPL, and should be managed at the bistro/devops level in my opinion |
| 13:41:59 | Araq | I prefer to fix Nim's problems instead of layering shit on top of broken stuff |
| 13:42:07 | Araq | ;-) |
| 13:42:09 | nasusiro | Araq: agreed |
| 13:42:11 | FromGitter | <mratsim> distro not bistro |
| 13:42:30 | Araq | aww, there is no bistro level |
| 13:42:43 | FromGitter | <mratsim> https://en.wikipedia.org/wiki/Bistro |
| 13:43:02 | Araq | yes, I know what a bistro is. |
| 13:43:21 | FromGitter | <mratsim> =) |
| 13:44:15 | nasusiro | Araq: I will try something and let you know in a minute |
| 13:44:38 | Araq | bistro -- food. distro -- toilet. you need both. |
| 13:48:34 | * | endragor quit (Remote host closed the connection) |
| 13:50:03 | nasusiro | Araq: why am I prohibited from using full path for CC inside nim.cfg? |
| 13:50:26 | Araq | cc only takes an enum value |
| 13:50:36 | Araq | use gcc.exe = "fullpath" |
| 13:50:42 | nasusiro | ah cool |
| 13:50:44 | Araq | or clang.exe etc, you get the idea |
| 13:52:07 | * | endragor joined #nim |
| 13:52:09 | nasusiro | yep, it works like a bullet! |
| 13:53:32 | nasusiro | I just added "usr/lib/ccache/gcc" to gcc.exe and caches compilation files. I edited a project of mine after I originally compiled it and took it a fraction of a second to recompile the whole thing |
| 13:54:04 | Araq | so ... in other words the Nim compiler is the bottleneck. |
| 13:54:20 | nasusiro | I guess :/ |
| 13:54:31 | Araq | until that is sorted out, I cannot advertise Nim's compile times :-) |
| 13:54:39 | nasusiro | ^_^ haha |
| 13:55:04 | Araq | but the good news is that --incremental:on is implemented. the bad news is it's untested. |
| 13:55:17 | nasusiro | so Nim does not have an IR before emitting C code? |
| 13:55:33 | nasusiro | or is C used as our IR code? |
| 13:55:44 | Araq | it has an IR but it's not serialized to any binary format. |
| 13:55:54 | nasusiro | that's not what I meant |
| 13:55:59 | Araq | now we have that, but it needs to be tested. |
| 13:56:05 | Araq | the AST is the IR. |
| 13:56:12 | nasusiro | ah yes, correct |
| 13:56:27 | nasusiro | I'm still learning about language and compiler design |
| 13:56:50 | Araq | and it's ok as an IR, we also have a control flow graph but algorithms on this thing suck |
| 13:57:09 | CodeVance | Is incremental compiling working |
| 13:57:46 | nasusiro | Araq: where should I use --incremental:on? with nim c or can I place it inside a nimscript as well? |
| 13:57:46 | Araq | CodeVance, got burned out after implementing it, will bring it to production quality later. |
| 13:58:43 | Araq | you shouldn't use it at all for now. unless you want to help with its development. |
| 13:59:04 | CodeVance | But it works sorta |
| 13:59:05 | CodeVance | Cool nice job |
| 13:59:19 | Araq | ? did you test it? |
| 13:59:53 | CodeVance | I'll have to compile nim devel to test it out |
| 14:00:14 | Araq | yeah well, expect immediate crashes |
| 14:01:07 | nasusiro | Araq: is there a possibility that the verbosity delays the compilation? If I use --verbosity:0 it compiles extremely fast. |
| 14:03:28 | Araq | unlikely |
| 14:05:49 | CodeVance | Are concepts still in development? |
| 14:06:09 | CodeVance | For me they seem to be working well |
| 14:06:39 | Araq | still in development but part of v1 now |
| 14:06:51 | Araq | and recently have received plenty of fixes |
| 14:07:03 | shashlick | araq: i've been posting full stack traces on crash reports, is that useful for your debugging? |
| 14:07:31 | Araq | not all that much, sorry, the first thing I do is to run 'koch temp c test' |
| 14:07:53 | nasusiro | I wanted to ask: what does koch mean, as a name I mean? |
| 14:08:34 | Araq | but tbh ... I'm not fixing bugs. I'm reviewing bugfixes. |
| 14:08:48 | CodeVance | is the difference between `of` and `is` that one works during compile time and the other at runtime? It's not mentioned in the system.nim file |
| 14:08:52 | FromGitter | <mratsim> koch is cook in German |
| 14:08:56 | Araq | so announce your tool on the forum, shashlick |
| 14:09:10 | CodeVance | nasusiro koch == chef |
| 14:09:12 | FromGitter | <mratsim> of is for inherited types |
| 14:09:27 | Yardanico | nasusiro, it's in the docs :) https://github.com/nim-lang/Nim/blob/devel/doc/koch.rst |
| 14:09:32 | Araq | of == instanceof |
| 14:09:35 | FromGitter | <mratsim> is is the canonical type matcher |
| 14:09:38 | Yardanico | https://nim-lang.org/docs/koch.html |
| 14:09:42 | shashlick | araq: okay, cause I run nim_temp to generate those traces but they are so long and I wonder if they really help in any way |
| 14:09:49 | Araq | is == "is of type" |

| 15:11:01 | FromGitter | <reisub0> Hi all. I've a small issue that's driving me nuts, regarding the AsyncHttpClient |
| 15:11:13 | * | nsf quit (Quit: WeeChat 2.1) |
| 15:11:59 | FromGitter | <reisub0> I'm basically trying to make an async HTTP Get request but the request itself has a multipart data string |
| 15:12:28 | FromGitter | <reisub0> There is no such proc that matches what I require in the getContent or get procs |
| 15:13:42 | Yardanico | @reisub0 are you sure you want to send MULTIPART with GET ? |
| 15:14:14 | FromGitter | <reisub0> The API I'm using seems to require it |
| 15:14:41 | FromGitter | <reisub0> curl -s http://localhost:3000/list -X GET -d'type=task' |
| 15:14:44 | FromGitter | <reisub0> Equivalent curl |
| 15:14:55 | FromGitter | <reisub0> I understood it to be equivalent to a multipart |
| 15:15:00 | FromGitter | <reisub0> Or was I mistaken? |
| 15:15:27 | Yardanico | @reisub0 this is not multipart, is it? |
| 15:15:31 | Yardanico | this is just normal data |
| 15:15:45 | FromGitter | <reisub0> Ah whoops |
| 15:15:59 | FromGitter | <reisub0> The function arguments do seem to call it multipart |
| 15:16:52 | Yardanico | "(HTTP) Sends the specified data in a POST request to the HTTP server, in the same way that a browser does when a user has filled in an HTML form and presses the submit button." |
| 15:17:21 | Yardanico | you can probably use "request" proc |
| 15:17:25 | FromGitter | <reisub0> Wouldn't the added -XGET make it a get request? |
| 15:17:27 | Yardanico | it has a body argument |
| 15:17:42 | FromGitter | <reisub0> Yeah, so I have to manually insert a=b in the body and add a crlf? |
| 15:17:56 | Yardanico | idk if you would need to add crlf by yourself |
| 15:18:16 | FromGitter | <reisub0> Yeah, I'll check it out |
| 15:18:21 | FromGitter | <reisub0> Thanks! |
| 15:18:28 | Yardanico | but really this api is bad if it requires you to use get requests with data in them |
| 15:18:57 | FromGitter | <reisub0> Yeah, it is |
| 15:21:23 | FromGitter | <kaushalmodi> Can someone write a nice blog post on the use of => and -> from futures? |
| 15:21:27 | FromGitter | <kaushalmodi> and also [] and lc? |
| 15:21:44 | Yardanico | well, docs explain them pretty much |
| 15:21:59 | Yardanico | lc is for list comprehension (like in python), but you need to specify types |
| 15:22:34 | Yardanico | and there are examples for -> and => |
| 15:22:39 | Yardanico | (for lc too) |
| 15:22:54 | FromGitter | <kaushalmodi> I cannot grasp the example in https://nim-lang.org/docs/future.html#=%3E.m,untyped,untyped |
| 15:23:01 | Yardanico | why? |
| 15:23:25 | FromGitter | <kaushalmodi> What's the relationship between -> and f in that example? |
| 15:23:38 | FromGitter | <kaushalmodi> And how does that link with the use of => in the next line? |
| 15:23:45 | Yardanico | well, this example just uses -> and => at the same time |
| 15:23:54 | Yardanico | -> is for proc types, => is for lambdas |
| 15:25:00 | Yardanico | line with => is the same as "echo passTwoAndTwo(proc (x, y: int): int = x + y)" |
| 15:25:27 | Yardanico | and proc passTwoAndTwo(f: (int, int) -> int): int = is the same as proc passTwoAndTwo(f: proc (x, y: int): int): int = |

| 15:26:49 | miran | regarding `lc` - the current syntax is IMO clumsy, so while i prefer list comprehensions in python, i use `map` in nim |
| 15:26:52 | FromGitter | <kaushalmodi> Yardanico: Thanks. It's still not clear.. But let me play around with those for a bit. I'll get back if I have questions |
| 15:27:07 | Yardanico | miran, maybe use mapIt instead? |
| 15:27:34 | miran | Yardanico: yeah, mapIt is nice, i'm using it also |
| 15:27:56 | Yardanico | and if you do a lot of mapIt filterIt etc and need performance you would use zero_functional module |
| 15:28:18 | miran | Yardanico: i use that too :) very nice library!! |
| 15:28:24 | miran | @kaushalmodi: start with `=>` |

| 15:33:14 | FromGitter | <reisub0> And this code is only literally one file |
| 15:33:28 | FromGitter | <Yardanico> @rtei |
| 15:33:44 | FromGitter | <Yardanico> @reisub0 can you post full code on gist if you can? |
| 15:33:56 | FromGitter | <Yardanico> also what is your nim version? |
| 15:34:30 | FromGitter | <Yardanico> with this code I get another error (which is because .body from asyncresponse is a future and you need to "await" for it) ⏎ ⏎ ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=5b3b978533b0282df4fcb39f] |

| 15:37:18 | FromGitter | <kaushalmodi> hmm.. future is renamed to sugar on devel? |
| 15:37:22 | FromGitter | <Yardanico> yes it is |
| 15:37:23 | miran | yup |
| 15:38:33 | FromGitter | <Araq> <AsyncHttpClient, url: string, body: None> is the problem |
| 15:38:44 | FromGitter | <Araq> plus some wrong compiler error message :-) |
| 15:41:26 | FromGitter | <reisub0> Are these optional parameters or are they all compulsory? |
| 15:41:33 | FromGitter | <reisub0> I did manage to get it to compile on this gist |
| 15:41:41 | FromGitter | <reisub0> https://gist.github.com/5bc3c481ecf5468064ec171e95f46d6b |
| 15:42:27 | Yardanico | @reisub0 if a proc has argument like "someName = someValue" then it's optional |
| 15:42:54 | shashlick | Araq: just posted about tissue on the forum - https://forum.nim-lang.org/t/4008 |
| 15:44:03 | FromGitter | <reisub0> @Yardanico Well, that doesn't make any sense because, then, it should have matched the proc prototype? |
| 15:47:28 | FromGitter | <kaushalmodi> this obviously doesn't work: ⏎ ⏎ ```import sugar ⏎ echo 1.(x => x + 1)``` ⏎ ⏎ what's the correct syntax? [https://gitter.im/nim-lang/Nim?at=5b3b9a90a99e1e52b712afbf] |
| 15:47:45 | miran | you're missing `map` |
| 15:47:57 | miran | oops, no |
| 15:48:11 | FromGitter | <kaushalmodi> yeah, I am not dealing with arrays/seqs |
| 15:48:15 | Yardanico | @kaushalmodi I don't think you can use anonymous procs with => from sugar module like this |
| 15:48:21 | Yardanico | but I might be wrong, I don't use it myself |
| 15:48:48 | FromGitter | <kaushalmodi> I am trying to *map* this in lisp: ⏎ ⏎ ```(let ((plus1 (lambda (x) ⏎ (+ x 1)))) ⏎ (funcall plus1 1))``` ⏎ ⏎ to `=>`. [https://gitter.im/nim-lang/Nim?at=5b3b9ae07e23133ecb2e4954] |
| 15:50:28 | FromGitter | <Araq> shashlick: omg, it's slick :-) |
| 15:50:50 | FromGitter | <Yardanico> @kaushalmodi you can use `echo (proc (x: int): int = x + 1)(1)` for this |
| 15:50:55 | FromGitter | <Yardanico> idk about => |
| 15:51:46 | FromGitter | <kaushalmodi> @Yardanico Yes, anon procs work.. I was just trying to learn the use of => |
| 15:51:59 | shashlick | araq: curious on our feedback, happy to add any features that help speed up this routine work |
| 15:52:22 | FromGitter | <Yardanico> well, it's probably used (as you might have guessed by the examples) to pass anonymous procs to other procedures in-line |
| 15:52:49 | FromGitter | <Yardanico> because nim can't infer type of arguments/return value without that |
| 15:52:56 | FromGitter | <Yardanico> (I think) |
| 15:53:07 | FromGitter | <Araq> karax uses => in one of its examples fwiw |

| 15:53:59 | FromGitter | <mratsim> @kaushalmodi this is the proper syntax: ⏎ ⏎ ```import sugar ⏎ echo (x => x + 1)(1)``` ⏎ ⏎ But you can’t use it because as Yardanico said, Nim cannot infer types here. [https://gitter.im/nim-lang/Nim?at=5b3b9c1760c38707835a3a2b] |

| 15:58:44 | FromGitter | <mratsim> (last link is the simplest) |
| 16:01:07 | FromGitter | <kaushalmodi> ok.. finally got this working.. the syntax looks very non-intuitive |

| 16:01:42 | FromGitter | <Yardanico> well, but it's still usefuk |
| 16:01:53 | FromGitter | <Yardanico> *useful :D |
| 16:02:05 | FromGitter | <narimiran> ...and now you can practice using `->` on the same example ;) |

| 16:02:29 | FromGitter | <mratsim> better? ;) |
| 16:02:45 | FromGitter | <narimiran> spoiler alert! :D |
| 16:02:48 | FromGitter | <kaushalmodi> @narimiran Yes, that part is easy now |
| 16:02:54 | FromGitter | <kaushalmodi> @mratsim yep :) |
| 16:03:03 | FromGitter | <kaushalmodi> but that jumbled order still bugs me |
| 16:03:30 | FromGitter | <mratsim> uh no, you need to define the proc then call it |
| 16:03:33 | FromGitter | <kaushalmodi> it's like you define a proc with the types and input value, but then you pass the proc definition when you actually call it |
| 16:03:55 | FromGitter | <narimiran> why jumbled? you can use this example now not only for plusOne, but for any other `int -> int` function |
| 16:03:59 | FromGitter | <mratsim> fn is not the actual proc though, it’s a stub |
| 16:04:04 | FromGitter | <mratsim> it’s instantiated at call site |
| 16:04:43 | FromGitter | <kaushalmodi> @mratsim hmm.. "but for any other int -> int function" makes sense |
| 16:04:45 | FromGitter | <mratsim> define the higher order function —> define it’s body —> call it with a function as parameter |
| 16:04:49 | FromGitter | <kaushalmodi> thanks |
| 16:04:50 | FromGitter | <narimiran> maybe it would be clearer if you didn't call it `plus1`, but `use2` |
| 16:05:03 | FromGitter | <kaushalmodi> @narimiran yeah.. I was translating directly from that elisp snippet |
| 16:05:35 | FromGitter | <kaushalmodi> but.. |
| 16:05:47 | FromGitter | <kaushalmodi> still the input arg gets hardcoded in that `use2` wrapper |

| 16:09:35 | FromGitter | <narimiran> yes, that is better :) |
| 16:13:15 | Yardanico | @Araq are there any examples on how to use --gc:regions? Because person in Telegram tells that he just added --gc:regions and he can use GCd code on esp8266 |

| 16:32:29 | FromGitter | <kaushalmodi> Is that a way to not hard-code the fn type to deal with ints? |

| 16:38:30 | FromGitter | <narimiran> notice the change in the order of parameters |
| 16:38:38 | FromGitter | <kaushalmodi> yeah.. was going to ask that |
| 16:38:46 | FromGitter | <kaushalmodi> I had the opposite order.. didn't work |
| 16:39:34 | FromGitter | <kaushalmodi> @narimiran 👍 Works! Thanks. |
| 16:40:01 | FromGitter | <narimiran> i think the type is inferred from the first parameter, so it has to be something with the known type - anonymous function isn't |

| 16:53:22 | Yardanico | @kaushalmodi but don't forget that you don't need => for lambda |
| 16:53:50 | Yardanico | oh I see |
| 16:53:57 | FromGitter | <kaushalmodi> Yardanico:.. yes :) |
| 16:54:04 | FromGitter | <kaushalmodi> the last line |
| 16:54:12 | Yardanico | anonymous procedures = lambdas, right? |

| 16:54:32 | FromGitter | <kaushalmodi> yes |
| 16:55:18 | FromGitter | <kaushalmodi> I just chose to hyperlink the => with #lambda and the other with #anonymous-procedures as the latter is the "official name" from Nim Manual |
| 16:56:36 | dom96 | makes sense :) |
| 16:58:16 | * | noonien quit (Quit: Connection closed for inactivity) |
| 17:01:05 | FromGitter | <narimiran> @kaushalmodi the example after the line "Here are few more examples of using => and ->:" won't work for some general type T |
| 17:01:16 | FromGitter | <narimiran> because of the signature of anonymous proc |
| 17:02:17 | FromGitter | <kaushalmodi> @narimiran You are right.. they are remnants of me trying to make generics work.. |
| 17:02:29 | FromGitter | <kaushalmodi> I will remove generics from those two int, flt examples |
| 17:02:30 | FromGitter | <kaushalmodi> thanks |
| 17:07:28 | FromGitter | <narimiran> no problem :) |
| 17:08:43 | FromGitter | <narimiran> btw, if you'll extend your list comprehension part - try to compare the syntax with map(It) for the same examples, to see what is clearer/nicer to you |

| 17:13:25 | * | Trustable joined #nim |
| 17:14:06 | FromGitter | <kaushalmodi> yes.. basically needed to grasp that the lambda has to be wrapped with fn type |
| 17:14:24 | Yardanico | lambda = anonymous procedure, remember! :P |
| 17:14:45 | FromGitter | <kaushalmodi> yes, yes.. I mean `=>` :) |
| 17:20:01 | FromGitter | <kaushalmodi> basically, anonymous procedures (or do notation) = fn signature + `=>` syntax |
| 17:21:12 | FromGitter | <kaushalmodi> if the fn signature doesn't need specifying, like in @narimiran's `map` + `=>` example, you can use the concise `=>` syntax to replace the more verbose anon proc/do |

| 18:15:29 | FromGitter | <kaushalmodi> OK, I couldn't resist, here are the list comprehension notes: https://scripter.co/notes/nim/#list-comprehension. Does it make it easier to understand the `lc[ .. ]` syntax? |
| 18:15:51 | FromGitter | <Araq> the lc syntax should go away IMO |
| 18:16:43 | ashleyk_ | are nim coders called nimbos |
| 18:19:04 | FromGitter | <kaushalmodi> @Araq I am not too attached to list comprehension.. just feels like something to have in the toolbox, just in case. |
| 18:19:17 | FromGitter | <narimiran> @Araq +1 for lc going away |
| 18:41:46 | FromGitter | <narimiran> @kaushalmodi the last example is IMO the only one showing the advantages of `lc` over `map`/`filter` |
| 18:42:56 | FromGitter | <Grabli66> Hi! Why my simple program with echo socket server eats 40Mb of memory? |
| 18:45:15 | krux02 | is someone here using gdb to debug Nim? |
| 18:45:19 | FromGitter | <narimiran> @Grabli66 is it compiled with `-d:release`? |
| 18:45:29 | FromGitter | <Grabli66> Yes |
| 18:45:45 | krux02 | cool |
| 18:46:08 | krux02 | I am working on something that might be of interest to you |
| 18:46:18 | FromGitter | <narimiran> krux02: i think that was the answer to my question, not yours ;) |
| 18:46:32 | krux02 | well yea |
| 18:46:47 | krux02 | then are you using gdb? |
| 18:47:13 | FromGitter | <narimiran> nope, i don't write bugs :P |
| 18:50:02 | FromGitter | <Grabli66> It's sad. It eats more than java :) |
| 18:50:06 | krux02 | narimiran, debuggers are not just there to find bugs, but also to make code execution explorable |
| 18:50:20 | krux02 | meaning debuggers can greatly help to understand a non buggy system |
| 18:50:56 | krux02 | Grabli66: have you tried using a memory profiler? |
| 18:51:13 | krux02 | normally you can profile where most of your memory is used up |
| 18:52:08 | krux02 | but be happy that it is not pythen. There a simple applet that does nothing more than listening to key presses to open a drop down terminal eats 50MB |
| 18:52:38 | FromGitter | <narimiran> krux02: i know, i'm just not at that level of knowledge (yet) to benefit from gdb |
| 18:53:05 | FromGitter | <Grabli66> krux02, how i can profile memory of nim program? |
| 18:53:07 | krux02 | narimiran, you will only get to that level of knowledge when you actually actively use it. |
| 18:53:41 | krux02 | well I don't think there are any nim specific programs. there are just programs written to profile C and C++ |

| 19:42:48 | krux02 | well I currently develop gdb pretty printing on a branch of Nim |
| 19:43:03 | FromGitter | <Araq> I'm trying to abandon LimeChat as it keeps reconnecting, annoying me |

| 19:43:46 | krux02 | I deprecated OSX |
| 19:43:51 | dom96 | Araq: Get XChat Azure |
| 19:43:59 | krux02 | but here is the nim pretty printer https://github.com/krux02/Nim/blob/macro-in-generic-type/nim-gdb.py |
| 19:45:11 | krux02 | all you need to do to get them working is "source nim-gdb.py" |
| 19:45:33 | krux02 | I don't know how to automatically load nim-gdb.py when a python program is started |
| 19:46:05 | krux02 | I found out a way on Linux, where I can embed the python script in a section of the binary. |
| 19:46:38 | krux02 | but even then you still need to enable the path of the binary for gdb to allow these pretty printers to be loaded automatically. |
| 19:47:27 | krux02 | and then debugging from the command line gdb works pretty nice |
| 19:47:33 | krux02 | print conf |

| 21:13:19 | FromGitter | <kaushalmodi> heh |
| 21:13:50 | FromGitter | <kaushalmodi> @Quelklef I am no expert at CSS, but can provide some help |
| 21:13:56 | FromGitter | <kaushalmodi> probably em vs rem? |
| 21:14:29 | dom96 | oh, swearing at CSS is fine :P |
| 21:14:39 | FromGitter | <Quelklef> lol @dom96 |
| 21:14:56 | FromGitter | <Quelklef> @kaushalmodi contained `span` was `0.8em`. should be fine, no? |
| 21:15:27 | FromGitter | <kaushalmodi> yeah.. using em instead of rem is a good practise for font sizing |
| 21:15:29 | FromGitter | <Quelklef> container is `font-size: 15px` |
| 21:15:35 | FromGitter | <kaushalmodi> em size is relative to the parent |
| 21:15:56 | FromGitter | <Quelklef> right |
| 21:16:33 | FromGitter | <kaushalmodi> if container is 15px (hope that this container is the body), and span is 0.8em, then that span should be 12px. |
| 21:16:55 | FromGitter | <kaushalmodi> the only place where I specify size in px is in body.. everywhere else is in em |
| 21:18:09 | FromGitter | <Quelklef> i mean yeah the font gets smaller but then makes the container bulge |
| 21:18:27 | FromGitter | <kayabaNerve> Just remove the CSS |
| 21:19:02 | FromGitter | <Quelklef> oh damn |
| 21:19:12 | FromGitter | <kayabaNerve> ez |
| 21:20:26 | FromGitter | <kaushalmodi> hmm.. difficult to tell anything without looking at the code |
| 21:20:39 | FromGitter | <kaushalmodi> even then, it could be difficult; this is CSS :P |
| 21:21:38 | FromGitter | <Quelklef> i can try and isolate the problem |
| 21:21:45 | FromGitter | <Quelklef> but at this point ive just settled for `1em` |
| 21:22:23 | FromGitter | <kaushalmodi> unless some other rule is changing that span's font size.. removing the font-size rule should default to 1em |
| 21:22:49 | FromGitter | <Quelklef> oh jesus |
| 21:22:53 | FromGitter | <Quelklef> I just pushed 2 commits |
| 21:23:05 | FromGitter | <Quelklef> can someone help me: how do I squash 3 pushed commits together |
| 21:23:30 | FromGitter | <Quelklef> i really need to learn git beyond clone, pull, and push... |
| 21:23:34 | FromGitter | <kaushalmodi> https://magit.vc Worth it even if you don't use emacs for anything else :) |
| 21:23:43 | FromGitter | <kaushalmodi> (above comment is serious) |
| 21:24:53 | FromGitter | <Quelklef> feels cheaty tho |

| 21:26:48 | FromGitter | <Quelklef> ayyy i did it |
| 21:26:53 | FromGitter | <Quelklef> stackoverflow lied to me tho |
| 21:29:08 | FromGitter | <Varriount> @dom96 Does choosenim have any documentation on how to checkout devel? |
| 21:29:51 | FromGitter | <kaushalmodi> @Quelklef Quick demo of squashing using Magit: https://i.imgur.com/tJ0kmvx.gifv |
| 21:30:44 | FromGitter | <Quelklef> That doesn't look all too different |
| 21:31:07 | dom96 | Varriount: choosenim --help? |
| 21:31:30 | FromGitter | <Varriount> Hrm, and it doesn't appear to like my 64 bit mingw |
| 21:32:20 | FromGitter | <kaushalmodi> @Quelklef The key strokes for squashing were literally `ri`, `s`, `s`, `s`, `s`, .. (`ri` for interactive rebase, `s` for sqash) |
| 21:35:11 | FromGitter | <Quelklef> oh yeah? |
| 21:35:24 | FromGitter | <Quelklef> well if I just don't use git then I only need zero keystrokes |
| 21:44:35 | FromGitter | <krux02> @Quelklef well yea that is true. But if you use git on github. you have a service that keeps your sourcecode alvife for you, even if you forget about it for years. change computer. Move to a new home. And burn your old mess you don't want to deal with anymore. It will still be there, even if you loose all the account information. |
| 21:45:51 | FromGitter | <Quelklef> I keep my code in a notebook under my bed |
| 21:46:02 | FromGitter | <Quelklef> servers crash. papers don't |
| 21:47:05 | FromGitter | <Quelklef> sorry @krux02 I wasn't being serious and I thought that was clear, but maybe not :P |
| 21:47:47 | krux02 | yea but the overhead of using git is big. It is a very valid argument |
| 21:50:14 | FromGitter | <Araq> @Quelklef no need to squash in a PR, we do that in the merge process |
| 21:51:36 | FromGitter | <Quelklef> @Araq oh! awesome |

| 22:33:08 | krux02 | Vindaar well rather +1 for github |
| 22:34:12 | FromGitter | <Vindaar> Fortunately I can like both, haha |
| 22:34:48 | krux02 | I use magit, too |
| 22:34:57 | krux02 | but for some reason I am not excited about it. |
| 22:35:01 | krux02 | I just use it |
| 22:35:32 | krux02 | it's good that it is there, but it is also again a program that only benefits the emacs people |
| 22:37:04 | krux02 | I would really like to like emacs. But I just can't it is so horrible to use |
| 22:37:05 | FromGitter | <Vindaar> Well, I'm excited about it, because imo it *really* makes using git a lot more comfortable. And I agree with @kaushalmodi: simply using emacs purely to use magit would be worth it for non emacs users |
| 22:37:18 | krux02 | but I still use it, because I don't know anything better |
| 22:37:24 | FromGitter | <Vindaar> although you're probably right that most people won't |
| 22:37:37 | FromGitter | <Vindaar> I really don't understand why you think it's horrible to use :( |
| 22:38:21 | krux02 | worst thing of all is this automatic breaking of the window layout and this automatik random abuse of windows and displaying other content than I wint it to display |
| 22:38:32 | FromGitter | <kaushalmodi> krux02: Yeah, don't get it why you find it so terrible |
| 22:38:49 | krux02 | to be honest it should work like blender |
| 22:38:49 | FromGitter | <kaushalmodi> Just make a list of top 5 things you don't like in it, and start fixing it in your config. |
| 22:39:23 | FromGitter | <kaushalmodi> krux02: The window layout "breaking" is a feature |
| 22:39:27 | FromGitter | <kaushalmodi> But you can take it |
| 22:39:45 | FromGitter | <kaushalmodi> Have a look at https://github.com/wasamasa/shackle |
| 22:40:14 | krux02 | I know about shacke |
| 22:40:24 | krux02 | the problem is I don't understand it |
| 22:40:35 | krux02 | I want to turn layout breaking off |
| 22:40:36 | FromGitter | <kaushalmodi> Try my config: https://github.com/kaushalmodi/.emacs.d/blob/master/setup-files/setup-shackle.el |
| 22:40:38 | krux02 | entirely |
| 22:40:55 | FromGitter | <kaushalmodi> But then how would `C-x 2`, `C-x 3` work? |
| 22:41:15 | krux02 | never ever automatically bring a buffer to the forground. Never split a window. |
| 22:41:39 | krux02 | C-x 2 etc should split |
| 22:41:44 | krux02 | but that is manual split |
| 22:41:56 | krux02 | it is just that emacs should automatically do split in the background |
| 22:41:58 | FromGitter | <kaushalmodi> shackle is syntactic sugar over the `display-buffer-alist`mechanics |
| 22:42:18 | FromGitter | <kaushalmodi> Your requirement seems extreme.. but should be possible |
| 22:43:01 | FromGitter | <kaushalmodi> Just advice the internal `display-buffer-pop-up-window` etc fns to *not* popup |
| 22:43:30 | krux02 | my requirement isn't extreme. I just can't stand it that emacs dosn't respect that I put time and effort in splitting my windows how I like them to be split. |
| 22:43:47 | krux02 | have you ever used blender? |
| 22:43:48 | * | nsf quit (Quit: WeeChat 2.1) |
| 22:44:34 | FromGitter | <kaushalmodi> no |
| 22:44:53 | FromGitter | <kaushalmodi> Another hack would be to set `split-height-threshold` and `split-width-threshold` to very high values |
| 22:44:56 | krux02 | it is has a tiling layout as well |
| 22:45:12 | krux02 | but it never "automatically" does a split |
| 22:45:32 | FromGitter | <kaushalmodi> Emacs to so much more than any single editor out there.. |
| 22:45:58 | FromGitter | <Vindaar> well you can just set `pop-up-windows` to `nil`. Then emacs shouldn't split anything by itself anymore |
| 22:46:04 | krux02 | yea and one of the things is breaking the layout. |
| 22:46:21 | krux02 | and the worst part of it. The behaviour is absolutely random and unpredictable |
| 22:46:35 | krux02 | sometimes things are displayed here, sometimes there |
| 22:46:52 | FromGitter | <kaushalmodi> May be it's just me, but the splits happen when I want without surprises.. |
| 22:47:05 | krux02 | sometimes when I want to switch to another buffer it changes the current buffer, somtimes it changes the buffer seen an another window |
| 22:47:31 | FromGitter | <kaushalmodi> Yes, there are hooks for that too |
| 22:47:49 | krux02 | I don't want hooks. I just want to disable it all globally with one switch |
| 22:48:16 | FromGitter | <kaushalmodi> When you get a chance.. try out shackle |
| 22:48:33 | FromGitter | <kaushalmodi> I have documented all the shackle configs in comments in my linked config above |
| 22:48:34 | krux02 | have you ever looked into `split-window-threshold'? |
| 22:48:52 | FromGitter | <kaushalmodi> I leave it at the default value because I want splits |
| 22:49:01 | FromGitter | <kaushalmodi> but you can set it to a very high value to prevent splits |
| 22:49:02 | * | ieatnerds joined #nim |
| 22:49:40 | FromGitter | <kaushalmodi> wait.. there isn't anything like *split-window-threshold* |
| 22:49:57 | krux02 | sorry that was the wrong one |
| 22:50:18 | krux02 | split-height-threshold |
| 22:50:41 | FromGitter | <kaushalmodi> yeah, I don't change those thresholds |
| 22:51:25 | krux02 | I changed the function emacs uses to split a window to not split windows |
| 22:51:45 | krux02 | because I wanted to disable spliting windows automatically |
| 22:51:57 | krux02 | I did so with the thresholds |
| 22:52:08 | krux02 | but the thresholds have this nice little details |
| 22:52:32 | krux02 | "‘split-window-sensibly’ may split it vertically disregarding the value of this variable." |
| 22:52:43 | krux02 | wft? |
| 22:52:54 | FromDiscord | <emekoi> is there a way to patch the standard library change the what the `magic` pragma points to? |
| 22:52:57 | krux02 | why do I set this variables when emacs just may ignore it at any time? |
| 22:53:26 | FromGitter | <kaushalmodi> it's documented.. I would then try to make `split-window-sensibly` to not do anything |
| 22:55:26 | krux02 | it is so much time that I lost in writing my emacs config |
| 22:55:37 | krux02 | and all just to make emacs do less |

| 23:05:32 | krux02 | not to forget sometimes and only sometimes emacs just decides not not split the buffer but to create a new emacs frame instead |
| 23:05:40 | krux02 | also totally random |
| 23:05:50 | krux02 | the same command might split or crate a new frame |
| 23:06:00 | krux02 | no predictability of the tool possible |
| 23:07:23 | * | floppydh joined #nim |
| 23:09:57 | krux02 | and sometimes I want to display a buffon on the right Frame, but emacs just refuses to do it and always does it on the left |
| 23:10:00 | krux02 | why |
| 23:10:31 | krux02 | btw I am not making this up, or this is something that I remember that it happened to be once |
| 23:10:48 | krux02 | kaushalmodi: this is happening right now |
| 23:10:50 | FromGitter | <kaushalmodi> krux02: Your Emacs experience has certainly been scarred. I'd suggest that you email [email protected] for help. The mailing list is very polite and helpful. |
| 23:11:45 | krux02 | I am sometimes on #emacs on irc |
| 23:11:56 | krux02 | they are nice and helpful |
| 23:11:58 | krux02 | that is true |
| 23:12:13 | krux02 | and the author of shacke is always there recommending shackle |
| 23:12:20 | krux02 | but still I don't understand shackle |
| 23:12:59 | krux02 | I don't install a package that I don't understand just for the hopes it could fix something where I don't know what it exactly fixes and what it might even make worse |
| 23:13:39 | FromGitter | <kaushalmodi> Hmm, I have never been on #emacs. But on the mailing list, the core devs like Eli and Stefan reply, which is awesome. Martin is the code dev for window buffer frame management. He is active in the help mailing list too. |
