| 00:57 | | * Mahal grumbles |
| 00:57 | < Mahal> | I know what I want to do is possible in Powershell, but I don't know what to google tom ake it clear to myself. |
| 00:58 | < Mahal> | (create a set of data and at the end of the script export it all to csv) |

| 00:59 | <&ToxicFrog> | "powershell output <data type> as csv"? |
| 01:00 | < Mahal> | what do I google for <data type> though? |
| 01:00 | < Mahal> | I mean |
| 01:00 | < Mahal> | I know how to get a set of variables in a foreach loop |
| 01:00 | < Mahal> | but I don't know what to do with them at the end of the loop so that they're stashed somewhere to be put in a CSV after I've got all the things |
| 01:00 | < Mahal> | ie: |
| 01:01 | <&ToxicFrog> | Oh. I don't know what datatypes powershell has for this. 2d array? |
| 01:01 | < Mahal> | $things = get-allthisdata |
| 01:01 | < Mahal> | foreach (thing in things) {get info A about Thing, get info B about thing} |
| 01:01 | < Mahal> | $things | export-csv things.csv |

| 01:02 | < Mahal> | somewhere between the { and } I need to [save the information in a Something] |
| 01:02 | < Mahal> | and while I realise this is pretty fundamentally easy programming |
| 01:02 | < Mahal> | I don't know what to google |
| 01:04 | <&Derakon> | Array? https://ss64.com/ps/syntax-arrays.html |
| 01:05 | <&Derakon> | $vals = @(); foreach (thing in things) {$vals += thing} |
| 01:05 | <&Derakon> | I have zero familiarity with powershell, maybe that semicolon is inappropriate. |
| 01:05 | < Mahal> | hrm |
| 01:05 | | * Mahal goes to try it |
| 01:12 | < Mahal> | thank you, that ... seems to be doing the thing |
| 01:13 | < Mahal> | I'm not 100% sure, but it seems to be. |
| 01:14 | <&ToxicFrog> | huzzah |
| 01:15 | <&Derakon> | \o/ |
| 01:15 | <&Derakon> | Glad I could help. :) |

| 01:34 | | * Mahal crosses fingers, hits "go" on a large script, hopes her host doesn't implode on RAM or something |
| 01:34 | < Mahal> | (it probably won't, but you never know your luck when you're doing things for the first time and thus almost certainly stupidly) |

| 02:27 | < Mahal> | oh ffs I am a moron |
| 02:27 | < Mahal> | I've just realised how I've done the CSV thing in the past |
| 02:27 | < Mahal> | why I forgot it today I do NOT know |
| 02:27 | < Mahal> | $things = get-allthedata |

| 15:17 | | * ToxicFrog pokes C++ unhappily |
| 15:18 | <&ToxicFrog> | I have a std::map<int, std::pair<bool, std::vector<REDACTED*>>> the_map |
| 15:18 | <&ToxicFrog> | I do something like: auto the_entry = the_map[key]; the_entry.first = true; |
| 15:18 | <&ToxicFrog> | And then later I check the_map[key].first, and it is false. |
| 15:19 | <&ToxicFrog> | And as I type this out, I realize that `auto` doesn't infer indirection levels (or at least not always), so I probably need `auto&` or I'll get a back a copy of the entry, won't I, even though operator[] is declared as returning a ValueType&? |

| 16:56 | < Jessikat`> | Yeah, auto will decay to value semantics |
| 16:56 | | Jessikat` is now known as Jessikat |
| 16:57 | < Jessikat> | Which is why you need explicit auto& in range based for loops for mutating operations |
