| 19:30 | <@ErikMesoy> | I have a repetitive pair of Python calls I would like to condense, of the form "Name = library.CreateThing(constant_1, constant_2, RelevantVariable)" followed by "Name.LibraryFunction(constant_3, RelevantObject)". I'm doing this mode of callpair for many Named things. |
| 19:31 | <@ErikMesoy> | I can condense the first on its own by creating a wrapper function on library.CreateThing which takes one argument and passes (constant-1, constant-2, argument). But is there a sane way to condense both of these into single wrapper call or the like? |
| 19:32 | <@ErikMesoy> | It seems nonobvious to me because the first call has to return the object, which makes it hard to call a method of the object in the same go. |
| 19:32 | <&[R]> | doStuff(library, relevantVariable, relevantObj) { library.createThing(C1, C2, relevantVariable).libraryFunction(C3, relevantObj) } |
| 19:33 | | * ErikMesoy squints. That's legal, calling like that? |
| 19:34 | <&[R]> | In most languages yeah |
| 19:35 | | * [R] isn't sure about Python |
| 19:37 | <&[R]> | Python supports it |
| 19:37 | <@ErikMesoy> | You are surely right but this is not doing what I wanted when I implement it, so time to figure out if I implemented wrong or described problem wrong. |
| 19:38 | | * [R] did that mostly as shorthand, wasn't meant to be legal code |
| 19:38 | <@ErikMesoy> | Python is shorthand+indent. :P |
| 19:42 | <@ErikMesoy> | Right, there was a third call that I had separated out for what surely seemed like a good reason at the time and so missed when condensing those two. |
| 19:48 | <@ErikMesoy> | Man, this fucked up the library so hard I'm getting a C++ assertion error. |
| 19:55 | <@ErikMesoy> | Aha. [R]: That call-on-call structure returned the result of LibraryFunction when I needed to get the result of CreateThing. Solution, wrapper function gets longer by doing those separately then a return, but at least the duplication is solved. |
| 19:55 | <@ErikMesoy> | Thanks. |

| 20:01 | <&[R]> | lol |
| 20:01 | <&[R]> | Yeah, it works because the first function returns a function, the result of that statement would be the return of the second function |
| 20:02 | <&[R]> | Some libraries like to do chaining, where pretty much every function returns this/self |
| 20:05 | <~Vornicus> | Python functions generally *don't* chain |
| 20:05 | <~Vornicus> | methods rather |
| 20:06 | <~Vornicus> | ostensibly to prevent you from pretending that the methods arecreating copies |
| 20:06 | <@ErikMesoy> | And now I'm trying to track down where a method got a positional argument from. |
| 20:06 | <&[R]> | I don't think any language does that by default |
| 20:12 | <@ErikMesoy> | Apparently it's the event that called it. |
| 20:21 | | Kindamoody|autojoin is now known as Kindamoody |
| 20:31 | <&ToxicFrog> | [R]: does which? |
| 20:33 | <&[R]> | <Vornicus> Python functions generally *don't* chain |
| 20:33 | <&ToxicFrog> | In that case I don't know what you mean by "by default" |
| 20:33 | <&ToxicFrog> | A language where object methods return this if there's no explicit return statement? |
| 20:34 | <&[R]> | Right |
| 20:35 | <&[R]> | It's something someone has to explicitly make the code do |
| 20:36 | <&ToxicFrog> | I also don't know of any languages where that's the default, and honestly I think it would be a kind of weird special case |
| 20:37 | <&ToxicFrog> | But there are definitely languages and libraries where it's the common convention |
| 20:37 | <&[R]> | Yeah |
| 20:37 | <&[R]> | I don't know about languages |
| 20:37 | <&[R]> | But libraries definately |
| 21:14 | <@ErikMesoy> | AD and I have been doing the stupidest thing in a while: discovering the Python winsound wrapper and then replicating his guitar exercises with Beep. http://pastebin.starforge.co.uk/4 |
| 21:15 | <@ErikMesoy> | Now to figure out how to multithread it for simultaneous beeps at different frequencies. |
| 21:17 | <@abudhabi> | Anyone know the name of the song, though? The person who taught me didn't. |
| 21:52 | <@gnolam> | https://twitter.com/skamille/status/864874648739209216 |
| 22:05 | <@ErikMesoy> | Huh. Why is pyinstaller throwing a syntax error on a line that works fine when I run the python program? (on a string format with the {var} syntax to be precise) |
| 22:06 | <&[R]> | Different python interpreter maybe? |
| 22:07 | <@ErikMesoy> | ...somehow I've managed to get pyinstaller for 2.7 and this is a 3.6 program. |
| 22:08 | <&[R]> | \o/ |
| 22:13 | | * ErikMesoy thwacks his command line to work with Python 3, but now pip isn't recognized any more. |
| 22:13 | <@ErikMesoy> | I feel I'm making something worse. |
| 22:15 | <@ErikMesoy> | Rather than chase a potential XY problem: what do you suggest I use to convert a Python 3 program into a standalone executable? |
| 22:15 | <@ErikMesoy> | (Windows) |
| 22:35 | <&[R]> | For ease of distribution? |
| 22:36 | <@ErikMesoy> | Yes. |
| 22:37 | <&[R]> | I'd probably just use chocolaty or whatever it's called |
| 22:37 | <&ToxicFrog> | So I've spent a while trying to debug why one of the C function definitions is getting emitted twice, resulting in a duplicate symbol error at compile time |
| 22:37 | <&ToxicFrog> | SPOT THE BUG |
| 22:37 | <&ToxicFrog> | CHECK_MALLOC(compiling->name, C_IMPL_BUFSIZE, "buffer for C source code"); |
| 22:37 | <&ToxicFrog> | c_append("\nvoid word_anon_%p() {\n", word); |
| 22:40 | <@ErikMesoy> | [R]: That seems to require the recipient installing Chocolatey. I am trying to minimize what the recipient has to do, ideally down to "Receive file, doubleclick file". |
| 22:40 | <&ToxicFrog> | Isn't there a "py2exe"? |
| 22:42 | <&ToxicFrog> | (the bug, btw: we don't truncate compiling->name after calling malloc, so sometimes malloc gives us back the same buffer we just used and freed for the previous function definition, and we end up appending the next function to it) |
| 22:43 | <@ErikMesoy> | py2exe appears to be for Python 2. |
| 22:44 | <@ErikMesoy> | (And there's no py3exe.) |
| 22:45 | <&ToxicFrog> | what? |
| 22:45 | <&ToxicFrog> | https://pypi.python.org/pypi/py2exe/0.9.2.0 |
| 22:45 | <&ToxicFrog> | "Build standalone executables for Windows (python 3 version)" |
| 22:45 | <&[R]> | https://pypi.python.org/pypi/py2exe/0.9.2.0 |
| 22:46 | <@ErikMesoy> | Oh. I was looking at the SourceForge page. |
| 22:48 | <&[R]> | Sourceforge? Is it 1998? |
| 22:49 | <@ErikMesoy> | It is there, evidently! :P |

| 23:12 | <@ErikMesoy> | Apparently it's still 2015 even there because py2exe is throwing "Tuple index out of range" errors and search is suggesting this is due to changes between 3.4 and 3.6. |

| 23:50 | <&ToxicFrog> | if too much stuff ends on the stack, it's impossible to fix it without resetting the AVR |
| 23:51 | <&ToxicFrog> | Because it uses the free space on the stack as a scratch pad for reading input |
