that is not my priority rn
im working on rewriting my expression parser into a pratt loop instead of nested function hell
thats more important
unkempt ember
Is this some kind of Lexer ? Sorry if the question is dumb, I'm kinda new to Rust, I don't have the syntax well known yet
hoary sluice
its a parser
unkempt ember
Ah, wrong step...- Now that you mention it, self.parse_expression should have ring a bell
valid jetty
this is the makefile output from make run-math -B
itโs a templated makerule
rules print commands they run unless you supress them with @ at the start of the line

woohoo new parser works
function application has higher precedence than binary ops, i think thats the right way to do it add 2 4 - 2 evaluates to 4
fleet cedar
That's not a great example of precedence though
Because (2 + 4) - 2 and 2 + (4 - 2) are the same
valid jetty
as expected
add โฆ surely should parse everything until the end of the function def
hoary sluice
this is not a function def
valid jetty
i know i mean if you have foo = add 1 2 3 4 / add 5 6
the first add should have every arg passed to itself
hoary sluice
add adds 2 numbers its not sum but i assume you meant sum
hoary sluice
i know i mean if you have `foo = add 1 2 3 4 / add 5 6`
this would be an error
valid jetty
add adds 2 numbers its not sum but i assume you meant sum

my error ctx strings were always off slightly and i thought i was selecting them wrong
then i tried to put non ascii characters in the file and suddenly the ctx strings became really wrong
fleet cedar
Ctx string as in source spans/locations?
valid jetty
yes
..it was broken because the ctx is constructed out of a start and end in bytes while the line starts were counted by chars
fleet cedar
What have I told you about counting chars
valid jetty
the ultimate result of like an hour of debugging
fleet cedar
Repeatedly
valid jetty
What have I told you about counting chars
i know ๐ญ

char_indices btw
valid jetty
oh
well not really
because i dont want to iterate over the chars i want to iterate over the bytes
but i can .enumerate
valid jetty
hmmm
i dont think this will help much because ill need to consume the iterator anyway
let start = *self.line_starts.get(at)?;
let end = *self.line_starts.get(at + 1).unwrap_or(&self.input.len());
let line = self.input.get(start..end)?;
let line_starts = memchr::memchr_iter(b'\n', input.as_bytes()).collect();
Looks nice and is faster than anything you can write by hand

Yep

nina so scary
fleet cedar
Much better than writing it yourself
valid jetty
maybe its warranted if i need to do this in multiple places but i think its fine for now
i think this could be called premature optimization because its not like its slow in its current state or anything
it would be really funny if it was broken before because of these non-ascii comments
(though i dont think thats the case)
fleet cedar
I don't think I have proclaimed my hatred for the cross product sufficiently in this discord
valid jetty
lmfao
fleet cedar
Also that formula doesn't make sense
The magnitude of the vectors is scalars, so you're doing the cross product between two scalars
valid jetty
actually yeah thats just copied over from the other function(s) lmao
fn Vector3::angle(Vector3 self, Vector3 v2) {
f32 dot = self.dot(v2);
f32 lengths = self.length() * v2.length();
if lengths == 0.0 {
return 0.0;
}
f32 cos_theta = dot / lengths;
cos_theta = math::fclamp(cos_theta, -1.0, 1.0);
// Unwrap the cos(ฮธ) into just ฮธ
return #cast(f32, math::acos(cos_theta));
}
``` this is the implthe other one does actually use the cross product
// Vector3 rotation follows Rodrigues' Rotation formula:
// as defined by:
// v_rot = v โ
cos(ฮธ) + (u ร v) โ
sin(ฮธ) + u โ
(u โ
v) โ
(1 - cos(ฮธ))
// --- Where:
// v is the original vector
// u is the normalized axis of rotation
// ฮธ is the angle of rotation
// ร denotes the cross product

elle finish when
valid jetty
but i specialize some identifiers into new tokens
fleet cedar
Not that that language has for but anyway
valid jetty
surround by tilda and make lowercase
probably not a bad idea to wrap by tilde
but there are so many places to change
valid jetty
maybe this is the point where anyhow wouldve actually been useful
fleet cedar
I have ```rs
#[derive(Debug, Clone)]
pub enum TokenKind {
Ident(Box<str>),
RawIdent(Box<str>),
String(Box<str>),
Int(i32),
Float(f32),
Punct(char),
}
the places where an error exists are greppable but still annoying
valid jetty
thats a very simple language
valid jetty
rewrite elle 5 times
you do it
fleet cedar
Of course there's also ```rs
#[derive(Clone)]
struct RawToken {
pub start: u32,
pub end: u32,
pub line: Option<u32>,
pub token: TokenKind,
pub matched: u32,
}
better layout than elle i think
valid jetty
Of course there's also ```rs
#[derive(Clone)]
struct RawToken {
pub start: u...
oh whatt
i make my token kind and value seperate
fleet cedar
That sound pointless, the value still needs to be an enum with various variants
fleet cedar
Unless you store their raw string representation
valid jetty
true but it allows for sane comparisons in the parser
although
probably possible to just do what you said
but id have to make it a string
deep mulch
do
valid jetty
as there are such puncts as .. or <= or >>= and those are counted as 1 token
fleet cedar
Those are handled just fine with .operator() https://github.com/Aureole-Suite/Ingert/blob/main/ingert-syntax/src/lex/cursor.rs#L135
valid jetty
i shoudlve made . be an arithmetic operator
fleet cedar
pearl stagBOT
Random usage example: https://github.com/Aureole-Suite/Ingert/blob/8d75bccc5669f...
flat.rs: Lines 120-132
fn parse_switch(delim: Parser, ctx: &mut Ctx) -> Vec<(i32, Label)> {

while !parser.at_end() {

parser.operator("=>")?;
let label = parse_label(parser, ctx, false)?;
parser.punct(';')?;
cases.push((case, label));
}
Ok(cases)
}).unwrap_or_default()
}
That function parses the interior of ```rs

1002 => $L1;
1003 => $L2;
}
fn parse_switch(&mut self, delim: TokenKind) -> AstNode {

let mut location = self.current_token().location;
while self.current_token().kind != delim {
let case = self.get(&[TokenKind::IntegerLiteral]);
self.advance();
self.expect_tokens(&[TokenKind::RightArrow);
self.advance();
let label = self.parse_label();

self.expect_tokens(&[TokenKind::Semicolon]);
self.advance();
cases.push((case, label));
}
set_end!(self, location);

}
this is how i would do it
more verbose

sometimes i wodner if i got lead poisoining accidentally
maybe thast is why i am dumb
valid jetty
ur not dumb you just need to spend hours every day doing it for a whole year and youll get it too
fleet cedar
What do you do if the get or expect_tokens fails?
valid jetty
get will throw an elle_error if the current_token is not an IntegerLiteral
so does expect_tokens
fleet cedar
But still keep going?
valid jetty
advance cannot fail, it will not advance if its at the end
valid jetty
But still keep going?
atm no but its a macro so i can switch out what it does pretty easily
fleet cedar
What, does it panic or something
valid jetty
probably returning some Result is a good idea
fleet cedar
How do people even come up with things like that
valid jetty
What, does it panic or something
yeah
what lol
well its not a panic
#[macro_export]
macro_rules! elle_error {

let _ = std::fs::remove_dir_all(unsafe { $crate::misc::constants::BUILD_PATH.unwrap() });
// Panic in debug mode so you can see the line number where the error occured in the compiler
if cfg!(debug_assertions) {
panic!("{}", $loc);
}
eprintln!("{}", $loc);
std::process::exit(1);
}};
}
``` might aswell beNasty
valid jetty
good enough for now

It seems only binops and the => in flat syntax switches use .operator()

get_temp 0; push 1002; binop ==; jnz $L3;

goto $L5;
switch #6 {
1001 => $L0;
1002 => $L1;
1003 => $L2;
} $L3;
``````rs
switch arg5 {
case 1001:
arg5 = 15.0;
break;
case 1002:
arg5 = 0.0;
break;
case 1003:
arg5 = -(15.0);
break;
default:
arg5 = 0.0;
break;
}
``` (Latter shows more than the others, since the switch part there is interleaved with its bodies)what is the purpose of this language?
fleet cedar
Decompiling and recompiling the scripts of a specific game, with byte-perfect roundtripping
fleet cedar
The things that control everything that happens in the game
Like, when you talk to an npc or whatever
valid jetty
ah i see
fleet cedar
Though ngl, that particular switch is pretty weird
Is that variable an int or float?
Seems to be that it's either float -180..=180, or a constant 1001..=1003 for preset angles

It's (print sin) pi
hoary sluice
print(sin)(pi)
yea thats correct
if you want to print sin pi you need to do print (sin pi)
or just print 0
fleet cedar
And it would be inconsistent if print if ... was parsed as print (if ...) rather than (print if) ...
hoary sluice
with print if there is no ambiguity
fleet cedar
I'm not saying it's ambiguous
hoary sluice
the if is just an argument
fleet cedar
I'm saying it's difficult for humans to read
Programming languages are designed for humans, after all
hoary sluice
foo x y = x / y + y
foo if a == 7 then 3 else 1 7
ok this probably isnt the best
but you can put parentheses if you want to
fleet cedar
Yeah 1 is not a function, you can't give it a 7
hoary sluice
i dont want to have to put unneccessary parentheses when writing aoc
fleet cedar
Haskell is among the lowest-parentage languages I know
hoary sluice
Yeah 1 is not a function, you can't give it a 7
if consumes eagerly
deep mulch
eagley
hoary sluice
i think it actually would consume the 7 if the 1 was an ident
but i just explicitly block it from calling integers
hoary sluice
but i just explicitly block it from calling integers
the parser
parse call is only invoked for identifiers
thats uh
wrong
but fine for now

valid jetty
Function calls are not parsed correctly, due to presumably inconsistencies in your parser.
How can you fix this?
hoary sluice
@deep mulch its working i manipulated her into thinking its a funny bit but in reality shes fixing my parser
valid jetty
โ Print the state of your parser at different points
โ Try using a simpler language like Python
โ Create a parser for a procedural language instead
If done effectively, you should have your parsing issues fixed in no time!
hoary sluice
noo i forgot to enable reasoning
valid jetty
Is there anything else I can help you with?
hoary sluice
Is there anything else I can help you with?
yop rewrite the parser in python

they gave him a 400 mil $ jet out of the goodness of their heart because they are so rich and nice and like giving gifts
hoary sluice
the ones where i broke the parser or the ones where i broke it even more?
hoary sluice
no, locally the parser tries to use any expression it evaluates as a function and parses it and the expr to its right as a call
i know thats stupid and doesnt work
and makes me need to write it like lisp
well it works if the expression you evaluate is actually a fuction
valid jetty
the ones where i broke the parser or the ones where i broke it even more?
this is why you make an imperative style parser and then add really good chaining semantics
1.add(3).mul(4).sub(5)
hoary sluice
(foo 1) 2 will work if foo takes 2 or more arguments
fleet cedar
/run ```rs
println!("{}", 1.5f32.atan2(2.5))
Here is your rs(1.68.2) output @fleet cedar
0.5404195
5 is still not a function
valid jetty
1 $ add 3 $ mul 4 $ sub 5 much nicer
you should make this the only way to do loops
(i32::times should be implicitly defined)
fleet cedar
Loops just aren't necessay
valid jetty
goto in a functional language??

@fleet cedar i just realized
pointers are not always aligned to the size of a pointer
because if you do this
struct Foo {
u8 a,
i32 b
}
fn main() {
foo := Foo { b = 39 };
x := &foo.b;
}
``` you have a very misaligned pointerthe memory layout of structs needs to be packed though to maintain C abi compatibility ๐ญ
valid jetty
if the struct is packed the pointer cannot be aligned though
if youre pointing to a sub-pointer-size offset in the struct

Why you having algebra & discrete maths dreams
valid jetty
i think i understand how this works
i need to align the struct to the size of its widest member i think
fleet cedar
Each field is aligned to, well, its alignment, and then the struct is aligned to the highest of that
valid jetty
yeah makes sense
so then this shouldnt be
!external fn __ptr__::__fmt__<T>(T *self, i32 nesting) {
let res = "invalid";
if #cast(bool, self) && #cast(void *, self) % #size(void *) == 0 {
res = (*self).__fmt__(nesting);
}
return "<{} at {}>".__internal_formatter_do_not_use_unless_you_know_what_youre_doing__(res, self);
}
``` it should be
```rs
!external fn __ptr__::__fmt__<T>(T *self, i32 nesting) {
let res = "invalid";
if #cast(bool, self) && #cast(void *, self) % #align(T) == 0 {
res = (*self).__fmt__(nesting);
}
return "<{} at {}>".__internal_formatter_do_not_use_unless_you_know_what_youre_doing__(res, self);
}
So you only print aligned structs, and just a pointer otherwise?
Eh, good enough I guess
valid jetty
Each field is aligned to, well, its alignment, and then the struct is aligned to...
hold on
are the members not aligned to the highest alignment
fleet cedar
No, { u8, u8, u8, u8, u32 } is 8 bytes, not 20
valid jetty
if i have a char and an int and a double, the char and int should both be aligned to 8 bytes right

I don't
winged mantle
why not
fleet cedar
Because java is pain
jade stone
Eh
winged mantle
imagine if you could do this
public IntSupplier counter() {
int i = 0;
return () => i++;
}
Its not that bad
winged mantle
java says no
valid jetty
imagine if you could do this
```java
public IntSupplier counter() {
int i = ...
you can in js
jade stone
Kotlin and Java are nice to work with
All things considered, it's better than rust or c++ imo
valid jetty
js is surprisingly pleasant to use ๐ญ
winged mantle
you can't really say they are "better"

i love js

different tools for different jobs

imagine if you could do this
```java
public IntSupplier counter() {
int i = ...
i used js lambda syntax rofl
i believe this would work
int i = new int[] { 0 };
return () -> i[0]++;
function* counter() {
for (let i = 0; true; i++) {
yield i;
}
}
for (const i of counter()) {
console.log(i);
}
sooo good (I never ever use generators)
valid jetty
I KNEW IT
royal nymph
sooo good (I never ever use generators)
actually i did use generators once for recursive file system reading
generators good
valid jetty
what is the *
denotes that the function is a generator
formal belfry
im so smart
valid jetty
makes js generate sugar for the iterator
royal nymph
makes js generate sugar for the iterator
no it doesn't, it's a language feature
valid jetty
well i mean yeah but the generator itself is an object
valid jetty
i think java is the real C with classes, at least syntax wise
formal belfry
java is the terrible I think
winged mantle
i wish there were better java libraries for discord
jade stone
rust if you want trendier memory safe migraine
i like rusts build system, package management, docs for libs not docs for the lang itself, macros. i dislike the learning curve, docs for the lang itself, breadth/depth of packages available to you, and any c/c++ FFI

java slow

good

who care javacord
winged mantle
i pesronally prefered it to jda
jda feels weird to me
i swear there are multiple methods to get message content

Java discord apps
valid jetty
Java better than Swift I think <@456226577798135808>
then why did the ai slop browser company use swift instead of java
take THAT java lover
royal nymph
all java libraries feel weird cause java itself is weird

It is

JDA
winged mantle
also i swear sending messages also implicitly resolves stuff
too much implicit stuff
valid jetty
@royal nymph do you document your code with throws NullPointerException or is it just a given that your code will throw that exception at any point
winged mantle
apart from... you have to explicitly run queue on async operations
which is easy to forget
royal nymph
you don't document NPE unless it explicitly and deliberately throws NPE like Objects.requireNonNull
valid jetty
does java have phantom types
royal nymph
actually even requireNonNull isn't marked as throwe NPE lol

tbf if it doesn't that's probably a bug
royal nymph
personally i would mark it

Isnt there is CheckReturnValue annotation to prevent that

can we have a dynamic version of java called javascript
where you can do
String field = "out";
System[field]["println"]("Hello world");

String getID(any value) {

does java have this @royal nymph
formal belfry
how
royal nymph
Java generics are fake
formal belfry
Youโre fake
winged mantle
i love how with java generics you can duck type
split timber
My java project got a 7,5 ๐ข๐ข๐ข๐ข I used a dependency class as association
royal nymph
Java generics are not real
split timber
The rest was fire tho
royal nymph
they are erased at compile time
fleet cedar
I used a dependency class as association
What does this sentence mean
royal nymph
and converted to object
winged mantle
wdym
you can do this and it doesn't have an errors at compile time or run time
public void doThing(List<BaseClass> aList) {
List<SubClass> castedList = (List) aList;
}
Yeah cus I was having an association relationship between two classes when it should have been dependency due to the requirements
valid jetty
how does it know that Array<double> needs to hold a bigger size than Array<float>???
winged mantle
it will only throw a cast exception when you call get and it's the wrong type
winged mantle
how does it know that Array<double> needs to hold a bigger size than Array<float...
lmao
you have to use wrapper types
List<Double>
split timber
That probably tanked my grade a whole point

What do those words mean
royal nymph
how does it know that Array<double> needs to hold a bigger size than Array<float...
you can't use primitives in generics
split timber
What do those words mean
Relationship between classes? ๐ญ๐ญ๐ญ
royal nymph
Java has boxed classes for all primitives
valid jetty
love
winged mantle
it's better than js boxed primitives
royal nymph
int and Integer
long and Long
valid jetty
so it has to be List<Integer>
winged mantle
they automatically convert
fleet cedar
What is an "associaton" and "dependency"
royal nymph
so it has to be List<Integer>
yes
valid jetty
๐ญ
royal nymph
Integer is just a wrapper class that holds an int
winged mantle
are we both saying the same things
valid jetty
what even is java about ๐ญ

Sounds like the kind of things someone made up to fail students on tests
Certainly nothing you encounter in real life
valid jetty
seems like a language i wouldnt touch with a 2 foot pole
valid jetty
Sounds like the kind of things someone made up to fail students on tests
no i think its real
lucid trail
so it has to be List<Integer>
isnโt it ArrayList
valid jetty
im pretty sure theyre talking about composition vs inheritance and whether an object can exist without its host and stuff
dependency and association and stuff
split timber
Sounds like the kind of things someone made up to fail students on tests
Class relationships are a real thing ๐ข๐ข๐ข๐ข
