| 07:50 | <&McMartin> | Ugh, I am tempted to become a bad person |
| 07:50 | <&McMartin> | It's looking like I have to take a detour from my Amiga nonsense to do a quick tutorial on vsnprintf(3) |
| 07:51 | <&McMartin> | And I'm trying to set the stage for what the problem is that it solves without basically assuming vsnprintf as the right answer in the problem statement |
| 07:51 | <&McMartin> | Because, let's be real here, everything about stdarg.h and the things that use it are batshit |
| 07:52 | <&McMartin> | But that means I find myself intentionally leaning away from correct answers like a youtube video essayist trying to avoid coming to the point so he has more room for paid sponsorships |
| 07:53 | <&McMartin> | Maybe I should just get to the point immediately, then say "basically everyone agrees that this is a bad idea and that the real solution is to have an I/O library that isn't shit and doesn't get you into this kind of trouble to begin with", followed by various examples through history, and *then* get to the sample code |
| 07:53 | <&McMartin> | Thank you, my noble virtual collection of goldfish and rubber ducks. |
| 07:58 | <~Vorntastic> | You're welcome |
| 08:41 | <~Vorntastic> | You could... Well it's easier with that, jan misali did a video about floating point numbers by gradually developing more and more complex versions of the system until it gets all the way to full strength. But that's a little trickier when you have to basically start with printf |
| 08:45 | <&McMartin> | Yeah, the chain *in C* is: |
| 08:45 | <&McMartin> | - stdout isn't well-defined or isn't what we need to write to -> fprintf |
| 08:45 | <&McMartin> | - also it isn't a FILE * -> snprintf, hand resulting memory buffer to whatever you want |
| 08:46 | <&McMartin> | - snprintf's API is really inconvenient, I want to wrap it in a way that lets me use printf syntax, forward transparently to snprintf, and then from there to the TCP connection or the window's console or the system log or whatever -> the actual topic of the article, revolving around vsnprintf and how it meshes with varargs |
| 08:47 | <&McMartin> | And so once you remove yourself from C's shackles, the answer is "snprintf's API is really inconvenient, *don't do that* in your stdlib" |
| 08:48 | <&McMartin> | via, say, being garbage collected and having some kind of String.Format method or operator (C#, Python 2), or straight-up string interpolation (C#, Python 3), or punting on all of that having individual methods for writing each kind of data to your stream (C++, C#, Java) |
| 08:48 | <&McMartin> | *on all of that and having |
