Remove Debug

This transform removes if statements that test __debug__ is True.

The builtin __debug__ constant is True if Python is not started with the -O option. This transform is only safe to use if the minified output will be run with the -O option, or you are certain that any if statement that tests __debug__ can be removed.

The condition is not evaluated. A statement is only affected if the condition exactly matches one of the truthy forms in the example below.

The removal is performed by the Remove Dead Branches transform, which this transform marks the if statements for. That transform must remain enabled (it is by default) for this option to have any effect, and it will keep a branch that cannot be removed without changing the meaning of the program. If a branch is removed and a statement is still required, it is replaced by a zero expression statement.

The transform is disabled by default. Enable it by passing the remove_debug=True argument to the python_minifier.minify() function, or passing --remove-debug to the pyminify command.

Example

Input

value = 10

# Truthy
if __debug__:
    value += 1

if __debug__ is True:
    value += 1

if __debug__ is not False:
    value += 1

if __debug__ == True:
    value += 1


# Falsy
if not __debug__:
    value += 1

if __debug__ is False:
    value += 1

if __debug__ is not True:
    value += 1

if __debug__ == False:
    value += 1

print(value)

Output

value=10
if not __debug__:value+=1
if __debug__ is False:value+=1
if __debug__ is not True:value+=1
if __debug__==False:value+=1
print(value)
