+# Style Guide
+This style guide has two modes that a guideline may be.
+
+`strict` means that prs will be rejected if they do not follow the guideline.
+
+`loose` means that a pr would be accepted but should later be fixed.
+
+## Empty Functions | loose
+Empty functions are typically a sign of an unfinished program or driver.
+
+In cases where there is a clear reason to have an empty function it will be allowed.
+For example FakeAlloc is only empty functions because it is a example of an the allocator api.
+
+### Allowed
+```rust
+/// in example.hb
+a := fn(): void {}
+```
+### Not Allowed
+```rust
+/// in fat32.hb
+a := fn(): void {}
+```
+## Magic Functions | loose
+'Magic functions' are what I am calling small helper functions that do one or two things.
+### Example
+```rust
+a := null
+magic_a := fn(){
+	a = 10
+}
+```
+The exact policy I want to have here is a bit fuzzy. I think that functions like this are nice in certain situations and not in others.
+Regardless of if you use them or not, put a comment above the function explaining rational.
+
+
+## Magic Numbers | loose
+The policy on magic numbers is make them const and have a comment above them. Typically linking to a source of information about the magic number.
+
+This helps cut down on magic numbers while making acceptable names and atleast half assed documentation. 
+
+Constants are inlined anyways, so its the same thing in the binary.
+
+```rust
+// The standard vga port is mapped at 0xB8000
+$VGA_PTR := 0xB8000
+```
+
+## Tabs Vs Spaces | strict
+I prefer for hblang code to use hard tabs.
+
+The rational behind this is that a tab is `1 Indent` which some developers might want to be various different sizes when displayed
+
+Soft tabs do not allow this user/editor specific as soft tabs always become spaces.
+
+Bottom line is this is an accessibility feature.
+
+There are some samples below.
+```
+\t means hard tab
+\n means new line
+\0x20 means space
+```
+
+### Allowed
+```rust
+if x == y {\n
+\tlog(z)\n
+}\n
+```
+
+### Not Allowed
+```rust
+if x == y {\n
+\0x20\0x20\0x20\0x20log(z)\n
+}\n
+```
