Comparison operators `== / >= /...` return `bool`. Logical operators `&& ||` return bool. Constants `true` and `false` have the `bool` type. Lots of stdlib functions return `bool`, not `int`. Operator `!x` supports both `int` and `bool`. Condition of `if` accepts both `int` and `bool`. Arithmetic operators are restricted to integers. Logical `&&` and `||` accept both `bool` and `int`. No arithmetic operations with bools allowed (only bitwise and logical).

Below, I just give examples of @fif_codegen tag:
|
|
* a pattern can be single-line (after the tag), or multi-line, surrounded with """
|
|
* there may be multiple @fif_codegen, they all will be checked
|
|
* identation (spaces) is not checked intentionally
|
|
* "..." means any number of any lines
|
|
* lines not divided with "..." are expected to be consecutive in fif output
|
|
* //comments can be omitted, but if present, they are also expected to be equal
|
|
* there is also a tag @fif_codegen_avoid to check a pattern does not occur
