<h1>Welcome to depell</h1>
<p>
Depell (dependency hell) is a simple "social" media site best compared to twitter, except that all you can post is
<a href="https://git.ablecorp.us/AbleOS/holey-bytes">hblang</a> code with no comments allowed. Instead of likes you
run the program, and instead of retweets you import the program as dependency. Run counts even when ran indirectly.
</p>
<p>
The backend only serves the code and frontend compiles and runs it locally. All posts are immutable.
</p>
<h2>Security?</h2>
<p>
All code runs in WASM (inside a holey-bytes VM until hblang compiles to wasm) and is controlled by JavaScript. WASM
cant do any form of IO without going trough JavaScript so as long as JS import does not allow wasm to execute
arbitrary JS code, WASM can act as a container inside the JS.
</p>

# HERE SHALL THE DOCUMENTATION RESIDE
## Enforced Political Views
- worse is better
- less is more
- embrace `unsafe {}`
- adhere `macro_rules!`
- pessimization == death (put in `std::pin::Pin` and left with hungry crabs)
- importing external dependencies == death (`fn(dependencies) -> ExecutionStrategy`)
- above sell not be disputed, discussed, or questioned
## What hblang is
Holey-Bytes-Language (hblang for short) (*.hb) is the only true language targeting hbvm byte code. hblang is low level, manually managed, and procedural. Its rumored to be better then writing hbasm and you should probably use it for complex applications.
## What hblang isnt't
hblang knows what it isn't, because it knows what it is, hblang computes this by sub...
## Examples
Examples are also used in tests. To add an example that runs during testing add:
<pre>
#### &lt;name&gt
```hb
&lt;example&gt
```
</pre>
and also:
```rs
<name> => README;
```
to the `run_tests` macro at the bottom of the `src/codegen.rs`.
### Tour Examples
Following examples incrementally introduce language features and syntax.
#### main_fn
```hb
main := fn(): int {
return 1;
}
```
#### arithmetic
```hb
main := fn(): int {
return 10 - 20 / 2 + 4 * (2 + 2) - 4 * 4 + (1 << 0) + -1
}
```
#### functions
```hb
main := fn(): int {
return add_one(10) + add_two(20)
}
add_two := fn(x: int): int {
return x + 2
}
add_one := fn(x: int): int {
return x + 1
}
```
#### comments
```hb
// commant is an item
main := fn(): int {
// comment is a statement
foo(/* comment is an exprression /* if you are crazy */ */)
return 0
}
foo := fn(comment: void): void return /* comment evaluates to void */
// comments might be formatted in the future
```
#### if_statements
```hb
main := fn(): int {
return fib(10)
}
fib := fn(x: int): int {
if x <= 2 {
return 1
} else {
return fib(x - 1) + fib(x - 2)
}
}
```
#### variables
```hb
main := fn(): int {
ඞ := 1
b := 2
ඞ += 1
return ඞ - b
}
```
#### loops
```hb
main := fn(): int {
return fib(10)
}
fib := fn(n: int): int {
a := 0
b := 1
loop if n == 0 break else {
c := a + b
a = b
b = c
n -= 1
}
return a
}
```
#### pointers
```hb
main := fn(): int {
a := 1
b := &a
modify(b)
drop(a)
stack_reclamation_edge_case := 0
return *b - 2
}
modify := fn(a: ^int): void {
*a = 2
return
}
drop := fn(a: int): void {
return
}
```
#### structs
```hb
Ty := struct {
// comment
a: int,
b: int,
}
Ty2 := struct {
ty: Ty,
c: int,
}
main := fn(): int {
finst := Ty2.{ty: Ty.{a: 4, b: 1}, c: 3}
inst := odher_pass(finst)
if inst.c == 3 {
return pass(&inst.ty)
}
return 0
}
pass := fn(t: ^Ty): int {
.{a, b} := *t
return a - b
}
odher_pass := fn(t: Ty2): Ty2 {
return t
}
```
#### struct_operators
```hb
Point := struct {
x: int,
y: int,
}
Rect := struct {
a: Point,
b: Point,
}
main := fn(): int {
a := Point.(1, 2)
b := Point.(3, 4)
d := Rect.(a + b, b - a)
d2 := Rect.(Point.(0, 0) - b, a)
d2 += d
c := d2.a + d2.b
return c.x + c.y
}
```
#### global_variables
```hb
global_var := 10
complex_global_var := fib(global_var) - 5
fib := fn(n: int): int {
if 2 > n {
return n
}
return fib(n - 1) + fib(n - 2)
}
main := fn(): int {
complex_global_var += 5
return complex_global_var
}
```
note: values of global variables are evaluated at compile time
#### directives
```hb
foo := @use("foo.hb")
main := fn(): int {
byte := @as(u8, 10)
same_type_as_byte := @as(@TypeOf(byte), 30)
wide_uint := @as(u32, 40)
truncated_uint := @as(u8, @intcast(wide_uint))
size_of_Type_in_bytes := @sizeof(foo.Type)
align_of_Type_in_bytes := @alignof(foo.Type)
hardcoded_pointer := @as(^u8, @bitcast(10))
ecall_that_returns_int := @as(int, @eca(1, foo.Type.(10, 20), 5, 6))
return @inline(foo.foo)
}
// in module: foo.hb
Type := struct {
brah: int,
blah: int,
}
foo := fn(): int return 0
```
- `@use(<string>)`: imports a module based of string, the string is passed to a loader that can be customized, default loader uses following syntax:
- `((rel:|)(<path>)|git:<git-addr>:<path>)`: `rel:` and `''` prefixes both mean module is located at `path` relavive to the current file, `git:` takes a git url without `https://` passed as `git-addr`, `path` then refers to file within the repository
- `@TypeOf(<expr>)`: results into literal type of whatever the type of `<expr>` is, `<expr>` is not included in final binary
- `@as(<ty>, <expr>)`: hint to the compiler that `@TypeOf(<expr>) == <ty>`
- `@intcast(<expr>)`: needs to be used when conversion of `@TypeOf(<expr>)` would loose precision (widening of integers is implicit)
- `@sizeof(<ty>), @alignof(<ty>)`: I think explaining this would insult your intelligence
- `@bitcast(<expr>)`: tell compiler to assume `@TypeOf(<expr>)` is whatever is inferred, so long as size and alignment did not change
- `@eca(<ty>, ...<expr>)`: invoke `eca` instruction, where `<ty>` is the type this will return and `<expr>...` are arguments passed to the call
- `@inline(<func>, ...<args>)`: equivalent to `<func>(...<args>)` but function is guaranteed to inline, compiler will otherwise never inline
#### c_strings
```hb
str_len := fn(str: ^u8): int {
len := 0
loop if *str == 0 break else {
len += 1
str += 1
}
return len
}
main := fn(): int {
// when string ends with '\0' its a C string and thus type is '^u8'
some_str := "abඞ\n\r\t\{35}\{36373839}\0"
len := str_len(some_str)
some_other_str := "fff\0"
lep := str_len(some_other_str)
return lep + len
}
```
#### struct_patterns
```hb
.{fib, fib_iter, Fiber} := @use("fibs.hb")
main := fn(): int {
.{a, b} := Fiber.{a: 10, b: 10}
return fib(a) - fib_iter(b)
}
// in module: fibs.hb
Fiber := struct {a: u8, b: u8}
fib := fn(n: int): int if n < 2 {
return n
} else {
return fib(n - 1) + fib(n - 2)
}
fib_iter := fn(n: int): int {
a := 0
b := 1
loop if n == 0 break else {
c := a + b
a = b
b = c
n -= 1
}
return a
}
```
#### arrays
```hb
main := fn(): int {
addr := @as(u16, 0x1FF)
msg := [u8].(0, 0, @as(u8, addr & 0xFF), @as(u8, addr >> 8 & 0xFF))

return pass(&arr) + msg[3]
}
pass := fn(arr: ^[int; 3]): int {
return arr[0] + arr[1] + arr[arr[1]]
}
```
#### inline
```hb
main := fn(): int {
return @inline(foo, 1, 2, 3) - 6
}
foo := fn(a: int, b: int, c: int): int {
return a + b + c
}
```
#### idk
```hb
_edge_case := @as(int, idk)
main := fn(): int {
big_array := @as([u8; 128], idk)
i := 0
loop if i >= 128 break else {
big_array[i] = 69
i += 1
}
return big_array[42]
}
```
#### wide_ret
```hb
OemIdent := struct {
dos_version: [u8; 8],
dos_version_name: [u8; 8],
}
Stru := struct {
a: u16,
b: u16,
}
small_struct := fn(): Stru {
