RenPy 6.11.0: 'return' outside function [KIND OF FIXED]

[iichan_lolbot]

My game starts in different ways depending on env vars.
So, some files starts with smth like:

Code: Select all

init 10 python:
    if  config_session:
        return
    #lots of resourse initialization here

It works in Ren'Py 6.10.2e and older, but broken in RenPy 6.11.0.
I guess, it is caused by Python update.

I do not want to add LOTS of spaces in ALL my init-sections to create smth like:

Code: Select all

init 10 python:
    if  not config_session:
        #lots of resourse initialization here

Is there another way to replace 'return' with smth?

It seems like you may want to do what you need within a Python function.

Code: Select all

init python:
    
    def do_stuff():
        if config_session:
            return
        else:
            # Do Stuff

    do_stuff()

At least in Python 2.6, it seems that returns outside of a function are considered to be a syntax error.

Still, there is inevitability to indent a vast amount of code...

Well, this is Python, after all.

Well, I've just "solved" the problem with indentation writing the python script... iichan_lolbot, please, contact me...

Is that a Python thing or something? I can't believe I get syntax errors for not indenting! Is there a program or something that anyone recommends that will do the appropriate indentations for Python to be happy?

[LordShiranai]

Yes, Python is very "indentation" dependent.

If find that the JEdit setup included with Ren'Py does as good a job as you're going to get with the indentation.

[Glazed Donuts]

I've been using Jedit, but sometimes it will automatically indent too much or too little (especially if I delete lines of code), and I have to figure out how much to get the indents right x_x is there a way to make it so that it will automatically indent the right amount of spaces no matter what? can this be configured in Jedit somehow?

Unfortunately, no. There are some cases where the editor really can't figure out what your actual intent with the code is.

Compare these pieces of Python code:

Code: Select all

if x == 1:
    print "x is 1"
x = 0

Code: Select all

if x == 1:
    print "x is 1"
    x = 0

Both of these are valid Python syntax. However, the indentation is important as the x = 0 assignment will always happen in the first snippet, but will only happen in the second snippet if x was previously 1. The editor is not going to be able to figure out what you really want.

In the programming world this is called a gotcha.

It's the biggest, most commonly occurring gotcha that I know of. Why people think it's a good idea (compared to other languages) is beyond me.

Why people think it's a good idea (compared to other languages) is beyond me.

It's because it prevents other gotchas, and generally improves programmer productivity.

One of the things we teach in the first-level programming is how to indent code. That's because it's hard to read (and reason about) the structure of code without being able to see the blocks visually, through indentation. Since indentation is such a big visual clue, often when reading code that is mis-indented, one can have problems understanding what it does.

Code: Select all

int i = 0;
for (i = 0; i < 10; i++); 
{
    printf("%d\n", i);
}

I'd argue the mistake in the above code

the extraneous semi-colon

is moderately hard to spot - especially if this is a more complicated bit of code. By enforcing the equivalence of indentation and block structure, you make the code easier to understand.

The second reason behind the choice is that it allows one to fit more lines on the screen at once, by not spending 1-2 lines per block on additional punctuation. Since having to scroll up and down makes you a little less productive, reducing scrolling should allow for an increase in productivity.

Oh, I still indent my code the old fashioned way. It's just that sometimes, the program gets so fickle about an indentation that's off by an inch and I get some crazy error for it @_@
