| 09:43 | <~Vornicus> | what |
| 09:46 | < catalyst> | this tells you so much about C++ as a language |
| 09:46 | <@TheWatcher> | It's spiders all the way down~ |
| 09:48 | < catalyst> | it's got everything - SFINAE, questionable use of types as insight into the compiler, poor standards compliance, hubris |
| 09:48 | <&[R]> | Imagine having the production code that would cause this to be revealed |
| 09:51 | < catalyst> | I've done similar things and I'm not proud |
| 09:57 | <@TheWatcher> | https://i.imgur.com/pFEGluP.jpg ~ |
| 10:02 | < catalyst> | yes and it's in a game which includes that man (in that role) |
| 10:03 | < catalyst> | so maybe that's on brand idk |
| 10:03 | <@TheWatcher> | :D |
| 10:03 | <&[R]> | The one where he bitches you out for playing it at the end of it |
| 10:03 | <&[R]> | ? |
| 10:03 | < catalyst> | I have oo idea |
| 10:03 | < catalyst> | no |
| 10:03 | < catalyst> | you think I play the games I make?! |
| 10:04 | < catalyst> | (I genuinely don't know, does he?) |

| 10:12 | < catalyst> | in 97 I was 11 :D |
| 10:15 | <~Vornicus> | gosh I thought you were my age |
| 10:25 | < catalyst> | I'm 34 |
| 10:26 | < catalyst> | is that a lot younger than you thought? |
| 10:30 | <~Vornicus> | yeah I'm turning 40 this year |

| 11:12 | <@gnolam> | Argh |
| 11:12 | <@gnolam> | Bail, damn you, bail! We're takin on water! The abstractions are leaking! |
| 11:13 | <@TheWatcher> | I sure you can get a cream for that. |
| 11:26 | <@sshine> | I'd like to grep 'import' that are not '^import' or '^@import'. if it were only one, I'd write: ack '(?!^)import' |
| 11:28 | <@sshine> | adding the second constraint seems to do nothing: ack '(?!^@?).?import' |
| 11:28 | <~Vornicus> | `[^@]import` |
| 11:28 | <~Vornicus> | if there's a character before it then it's not at the beginning |
| 11:29 | <@sshine> | the ^ is the beginning-of-line symbol |
| 11:29 | <@sshine> | I think [^@] means literal ^? |
| 11:29 | <@sshine> | sorry for regex dialects :) @ is literal, ^ is beginning-of-line |
| 11:29 | <&[R]> | [^@] means any one character that isn't @ |
| 11:29 | <~Vornicus> | isn't it negate, inside of brackets |
| 11:29 | <~Vornicus> | that |
| 11:30 | <@sshine> | ah yes |
| 11:30 | <@sshine> | so [^@]import avoids the lines that begin with @import, but not the lines that begin with just import. |
| 11:31 | <&[R]> | $ printf '%s\n' {,^,@}import | grep -E '^[^\^@]?import' |
| 11:31 | <&[R]> | import |
| 11:32 | <&[R]> | Oh, derp |
| 11:32 | <@sshine> | it seems, incidentally, that (?!^@).import works because the . fails to match if import is at the beginning of the line. |
| 11:32 | <@sshine> | I found that by mistake. |
| 11:32 | <@sshine> | https://regex101.com/r/JHOt1J/1 |
| 11:33 | <@sshine> | regexes are so hack-ish. |
| 11:33 | <@sshine> | "oh, it worked by accident? good enough for me!" |
| 11:34 | <@sshine> | thanks guys :) |
| 11:35 | <&[R]> | ^[^@].*import |
| 11:35 | <&[R]> | I think that's what you want |
| 11:36 | <&[R]> | [^@] will match any non @ character meaning the line can't start with import (unless import is twice in the line), .* will let it match import later in the line |

| 12:07 | <@TheWatcher> | Heh, that's neat |
| 12:08 | <@sshine> | [R], it is. |
| 12:08 | <@sshine> | [R], that one is also more easily extensible wrt. handling whitespace. |
| 12:08 | <@sshine> | [R], thanks! |
| 13:41 | <@sshine> | haha, I'm trying to learn IntelliJ shortcuts, and hitting one for "delete current line", I literally get "Shortcut conflicts: Two shortcuts are occupying this." -- this is a peculiar way of overloading the keyboard to the extent that it isn't useful by default. |
| 13:42 | <@sshine> | also, shortcuts are *completely* different between Mac and Windows/Linux. "Go to line" is Ctrl+G or Command+L. |
| 13:43 | <@sshine> | I think Vim/Emacs have a tendency towards adding hundreds more shortcuts than most single users will find and use, but at least, they're there for googling, and everyone can focus on and extend their preferred subset. |
| 13:43 | <@sshine> | but at least... those shortcuts mostly work by default. :-D |

| 22:42 | < john_cephalopoda> | Designing this assembler is such a hassle. Single-pass vs. double-pass, configuration of ELF headers, one big assembly vs. assembly object files and linking... |
| 22:45 | <&McMartin> | If you're going to be doing ELF, save yourself all the pain and just be multipass. There's no reason to eat the shit that is backpatching if you don't have to... and that goes double when instructions might be of variable length depending |
| 22:45 | <&McMartin> | I forget if x86 does that |
| 22:48 | < john_cephalopoda> | I am currently using Forth to directly parse assembly-style code. So for "MOV EAX, EBX", I write "EAX EBX asm:mov". The "EAX" and "EBX" words put an ID on the stack, the "asm:mov" word takes the two top stack elements and juggles them around in order to create the proper instruction. |
| 22:49 | | * McMartin nods |
| 22:51 | < john_cephalopoda> | I have implemented two-pass with RISC-style opcodes (movi, movr, etc) and single-pass with Intel-style opcodes (mov does every mov operation, operands have a type identifier). |
| 22:52 | < john_cephalopoda> | It all works, I can assemble ELF executables for Linux-i386 and Barebones x86 with either assembler. But I am happy with neither. |
| 22:55 | < john_cephalopoda> | Another option would be to not make the assembly Forth code. That would make parsing more difficult and would turn something that's practically a macro assembler into a plain assembler with limited extra functionality. It's so hard to decide, and all options are valid results since it's a hobby project I'm doing myself for the fun of it... |
| 22:56 | <&McMartin> | Mmm |
| 22:56 | <&McMartin> | That's an interesting thought |
| 22:56 | <&McMartin> | I know the answer for Lisp-like assemblers |
| 22:56 | <&McMartin> | Which often did this on purpose because then you get All Of Lisp as your preprocessor, which is pretty boss |
| 22:56 | <&McMartin> | And Forth would likely have similar neat bits |
| 22:57 | <&McMartin> | I guess in the modern world Gradle kinda does this, with the build files being groovy scripts under the hood and that makes them more procedural if you need it |
| 23:00 | < john_cephalopoda> | I think I'm veering towards the "The asssembly code is Forth code" + Two-pass route. Single-pass is nice but struct-like things are a pain in Forth and I need those for keeping track of addresses. |

| 23:50 | < Yossarian> | Not a coding question, but what is the general thought on encrypting your home partition? Assume drive is an SSD. |
| 23:51 | <~Vornicus> | My general understanding is that it is a relatively limited protection |
