You can still put control sequences in filenames, but common things like ls will escape them, and most modern terminal emulators refuse to implement control sequences they consider security risks, or at least disable them by default

raminasi posted:200 for everything is definitely an extant pattern. Honestly I think it's fine if it's documented and consistent and the responses are machine-readable (i.e. you don't need to parse error strings). If

That’s not quite enough, because people want to add methods that extend existing data types. Like, extending methods. Extendy methods. Something like that.

Hammerite posted:love to see a library in which every property accessor has a documentation string that says either "gets the value of the Foo property" or "sets the value of the Foo property" as though that were helpful to anyone, clearly solely because there is some policy saying that every method and property accessor is required to have a documentation string so they can claim they reach some documentation target and nothing anywhere in any documentation or comment that explains what Foo means

brap posted:fwiw the compiler actually eliminates the unnecessary comparisons in this case. Does it? Like, it could in this case, but I’d be kind of surprised if they bothered to implement that, given that it’s only possible in certain specific situations and the benefit is likely to be insignificant unless there are vast numbers of cases.

rjmccall posted:It falls out of any basic CSE / GVN optimization to the point that it would be weird not to do it. And eliminating redundant branches is a very worthwhile optimization in general; people tend to write a lot of redundant range checks, and reducing branch density is very good on modern processors. That’s happening at a lower level surely? I was talking about specifically the difference between the switch vs if/else chain, where I’d be surprised if the compiler emitted significantly different code for each.

OddObserver posted:PowerShell looks like they really wanted to show off finally having good tab completion. Powershell is awful for completion tho because they went with verb-noun, which is generally bad because it’s easier to guess the noun than the verb and you’re more likely to want to ask “what can I do to a Folder” than “what kinds of thing can I Get” AWS cli is terrible for exactly the same reason

Falcon2001 posted:I mean the one class per file is a Java thing though right? And in Java you can't have just a function hanging out by itself, it has to be contained within a class, so probably that's where that particular brainworm comes from. One public top-level class per file. You can have any number of nested classes, and any number of non-public top-level classes. In a year or so you’ll also be able to define the main() function without needing a class at all, thanks to the magic of JEP 445! There’s amazing innovation going on in the Java community, idk why people think it’s oldfashioned

Surprise T Rex posted:Are Java enums sort of like Union types? From a C# perspective they’re confusing since in C# it’s just a strongly typed list of name-to-Integer mappings. They’re sugar for collections of singletons with special compiler support to let you use them in switch statements, and special support classes like EnumSet and EnumMap that take advantage of the compiler-generated ordinal() method to use them as efficiently as integers in other common situations.

more falafel please posted:goddamnit larry how does it not default to $_ (probably because it's in list context and all the args get collapsed, once again goddamnit larry) I think technically your code uses the result of “reverse split” in scalar context (i.e. the number of words), to join an empty list. So the result is always an empty string. Perl is fun!

QuarkJets posted:Native Python sure, TKinter sucks, but Python also has extremely good support for Qt and Qt is still a gold standard in desktop gui design, so that'd be a reasonably good choice. Put it this way … if you’re writing python today, most likely you’re writing it either in vscode (electron) or pycharm (java). I think the desktop apps I use regularly (ignoring the browser itself and stuff built into the os) are a pretty even split between electron, java, and native qt. I don’t think any of them are written in python.

The problem with it is that having a case statement in the middle of a loop is the kind of thing that might plausibly be undefined behavior or a compiler-specific extension. It’s obvious what the code intends to do, but it’s not a common idiom, so unless you’re familiar with the trick, it’s not obvious whether it will actually do that reliably, even if you run it and it seems to work on your machine. That’s why it’s bad code.
