Each branch instruction class’s scope variable reverting setting¶

These interfaces execute with statement code¶

These interfaces execute the code in each branch instruction regardless of the condition, and variables are updated.

For example, the following code of the condition is False, but the value of int is 20 on the Python:

import apysc as ap

ap.Stage()
condition: ap.Boolean = ap.Boolean(False)
int_1: ap.Int = ap.Int(10)

with ap.If(condition):
    int_1 += 10
assert int_1 == 20

This condition is skipped in JavaScript (converted code) since the condition is not satisfied.

Scope variables reverting setting¶

The If, Elif, and Else classes have the arguments of the locals_ and globals_ (basically set the locals() and globals() built-in functions return value). If these arguments are specified, the scope variables are reverted when ended each scope (e.g., If scope).

This interface is occasionally helpful when you don’t want to update the variables in each branch instruction scope.

import apysc as ap

ap.Stage()
condition: ap.Boolean = ap.Boolean(False)
int_1: ap.Int = ap.Int(10)

with ap.If(condition, locals_=locals(), globals_=globals()):
    int_1 += 10
assert int_1 == 10
