Code is refolded automatically when pasting

[steve-biggs-fox]

Consider the following code:

"""
Header line describing the program

License information etc
"""

class MyClass:

    def myMethod(self):
        pass

    def myOtherMethod(self):
        pass

When all is folded, it will be like this:

Header line describing the program

class MyClass:

I like to work with the header folded but the class open so I can see the methods (maybe some of the methods will be open too but that doesn't make any difference so let's ignore that for now), e.g. like this:

Header line describing the program

class MyClass:

    def myMethod(self):
    def myOtherMethod(self):

However, if I paste two or more lines between the folded header line and the open class, then the class re-folds itself, which I do not want.

Expected outcome after paste:

Header line describing the program

myStaticVariable = 1
myOtherStaticVariable = 2

class MyClass:

    def myMethod(self):
    def myOtherMethod(self):

Actual outcome after paste:

Header line describing the program

myStaticVariable = 1
myOtherStaticVariable = 2

class MyClass:

As noted above, it doesn't make any difference if methods within the class are open - the whole class is re-folded. Note also that pasting a single line works OK (i.e. class stays open) - it is only a problem when pasting two or more lines.

Also, there is a problem when typing in the lines manually. This happens when a new line is inserted. The problem is that the folded methods get messed up, e.g. the fold is shifted up or down so that the fold text is blank or the fold is only on the contents of the method but the name line is unfolded.

Do you have the FastFold plugin installed? If not, I think it will solve this problem.

I have this problem as well, and FastFold doesn't seem to solve the issue. It also folds expanded snippets automatically, so that:

"test" + expand-mapping resolves to

def test_description():  # fold

instead of

def test_<description>():
    <snippet>

where < > are snippet placeholders.

This prevents placeholders from being used.

This (and the OP issue) appear to be "resolved" if you zR on the file before pasting or snippet-ing.
