you can use gdb. you can also make it visual with vscode. so you can step through your code and check values etc.
07:52
there are also other frontends for gdb such as https://github.com/nakst/gf

1. Learning Unreal -> 2. Reaching the point of the need of a vesrion control system (decides on git) -> 3. Researches and finds that github is limited in the context of git-lfs -> 4. Looks up CodeBerg (reads faq/licences) -> 5. Looks up UE5 search term in CodeBerg's repos for the fun of it -> 6. Find a project -> 7. The project is a little broken (easily fixed) -> 8. The broken link is replaced with the correct one in the .uproject file -> 9. While fixing it needs to find the link and sees that an app isn't opened by default such as ddnet://address -> 10. Searches for way to add that default behaviour in their distro's forums -> 11. Ends up finding a thread which mentions rofi -> 12. Thinks rofi is pretty cool and continues to find very cool configurations -> 13. In the same thread there's a mention of ytfzf (posix script to search yt videos from terminal and watch them in mpv) -> 14. Starts to write this msg in #developer to show how much organized and collected they are.

it's the last missing piece in my safe Rc<RefCell> impl instead of having a RefMut and work on it, you give a closure.. but a normal closure has to few restrictions.. so i want ALL captures to have this restriction instead

@Ryozuki FFR assuming i don't use any global variables. Do you know any lib that parses all variable names of a closure (only from syntax, so || { whatever ... }) that are bound to it? i mean u can probably create some weird edge cases like let a: fn() = somefunc; but let's not deal with those xd i basically need the captures of a closure by name i am 100% sure one of your quadtrillion tabs must have had the same weird problem i have rn 😏

Jupstar ✪ 2024-01-05 13:10:39Z
i have a derive macro that implements a "hierarchical value" to determine if your component is higher level than another one => you can safely use Rc without leaks but if you go even further and also restrict Rc<RefCell> to never allow RefMut outside of your class, then you can restrict all paramters of your function to only allow lower level components => no higher level component is used inside your function. and thus it's not possible to borrow mut twice (this component at least) the component itself also has wrapper that hides Rc<RefCell> so it cannot be acccessed. So basically the goal is to never call borrow_mut, only the macros do it. and the same macros apply the restrictions to the func parameters

Addressing Rust optimization failures in LLVM
GSoC 2023 LLVM Final Report
14:44
1. Constant Propagation for uniformly patterned aggregated types on InstCombine Originally, no implemented constant folding can handle constant global aggregate-type values with variable index access. This was the first issue I tackled on LLVM. Throughout the project, I decided to split the problem step by step and make the patch as small as possible.
14:44
2. Removal of memcpy introduced on the attributed with readonly, noalias and nocapture on MemCpyOpt LLVM function arguments can have attributes, i.e. noalias shows there is no other pointer variable that points to the same as the argument, and readonly shows that the argument is not modified in the function. Functions attributed noalias and readonly at the same position show invariance during the execution of the functions. If it’s also attributed with nocapture, we can omit the memcpy of argument to pass for such functions. But to completely remove that memcpy, we need to attach alignment attributes to the arguments.
14:44
3. Attaching wrapping flags for the switch to look up table conversion on SimplifyCFG This issue reports dropped nsw (no signed wrap) flags for arithmetic instructions on SimplifyCFG and InstCombine. (This is motivated by Rust Issue reported in the issue). This can be addressed by SimplifyCFG and InstCombine/InstSimplify. For the former SwitchToLookupTable on SimplifyCFG is the place to handle this.

4. Stack Move Optimization, which merges the allocas neither captured nor simultaneously used Rust’s move semantics introduce memcpy when values are 1) rebind to the variables, 2) passed by value to the functions. But for most cases, also due to the property of the Rust references, both pointers aren’t used simultaneously. By using alias/dataflow analysis, we could find such patterns on LLVM-IR. Originally, liveness-analysis approach was proposed, but it stalled for a long time. So I pushed forward by splitting it’s patch.

not only that expensive optimizations take longer the more code you have so huge code bases would be really slow to compile u already see this with LTO

I like requiring parentheses instead of setting a precedence for & and | btw 😉
17:13
i.e. (a & b) == c is fine, a & (b == c) is fine, but a & b == c is a syntax error
17:16
in C, 0 & 1 == 0 evaluates to 0, but in python, it evaluates to True

ok no
20:09
that's just the thing it would fix

i got that wrong, but it's not fixing it xD
20:13
i just find it weird that it simply does nothing.. --verbose also shows nothing
20:14
it could at least say "no i can't do that and skip" or smth

hi_closure!([a: i32, b: &i32], |arg: i32| -> i32 { arg + a + *b + 1 }) my custom explicit closure syntax xdd
20:26
well if you missing an item in the capture list the error is a bit useless: can't capture dynamic environment in a fn item use the `|| { ... }` closure form instead but i guess i'll just add to docs and call it a day xdd (edited)

i want all captures to have a trait implemented

i need to make sure they do

else the closure is not panic-safe for Rc<RefCell>

Ah, they are probably also not fixed form closures

Jupstar ✪ 2024-01-05 20:29:01Z
gimme a second
20:29
i give u an example
20:31
struct MyStruct { a: i32, } impl MyStruct { fn test<F>(&self, a_normal_closure: F) where F: Fn() { a_normal_closure(); } } fn main() { let a = Rc::new(RefCell::new(MyStruct {a: 1})); let b = a.clone(); let c = a.borrow_mut(); c.test(|| b.borrow_mut().a += 1); }
20:31
bcs i passed b into the closure and have a borrowed mut
20:31
=> panic
20:32
but if MyStruct implements Hiarc trait then it can't pass itself into that function call, bcs the hirarchical value must be smaller that's not 100% how i did that, bcs actually there is a wrapper around it
20:33
but u could imagine it similar to this
