You will get a file named .swp if you open a new unnamed buffer and
enter text into it.  For example, start Vim as

$ vim

and add some text,

ahello

Extension is the part of the filename. File `.swp` does have the filename.

This can be generated when you view a directory.

Why .swp can be generated?

[Peng Yu]

Hi, When I open a file, a file like .somefile.swp will be generated.
But why a file .swp (without the filename) can be generated?

Off my head:

function! IsBoolean (option)
  if !exists("&" . a:option)
return 0
  endif
  let bool = 1
  exe "let old = &" . a:option
  try
exe "set no" . a:option 
  catch
let bool = 0
  endtry
  exe "let &" . a:option . " = " . old
  return bool
endfunction

I’m not sure setting and resetting the option is 100% harmless for all
options, though.

Best,
Paul

Hi!

Some vim options are boolean, i.e. integers with the possible values 0
and 1. You can, e.g., set `ai` and `noai` or use `let &ai = 1`. Other
options are numeric/integer or string values.

type(&option) can only be used to distinguish string from bool/int
options. exist('&noai') returns 0, so it cannot be used to distinguish
bool from int options. Is there another way to determine whether an
option is a bool (an int that takes only the values 0 or 1) or an int?


Some hacks, I can think of:
- parsing $VIMRUNTIME/doc/options.txt
- try/catch block around :set inv

BTW: What is the problem with treating boolean options like integer?

Best,
Christian

How to determine whether an option is boolean?

[lith]

Hi!

Some vim options are boolean, i.e. integers with the possible values 0 and 1. 
You can, e.g., set `ai` and `noai` or use `let &ai = 1`. Other options are 
numeric/integer or string values.

type(&option) can only be used to distinguish string from bool/int options. 
exist('&noai') returns 0, so it cannot be used to distinguish bool from int 
options. Is there another way to determine whether an option is a bool (an int 
that takes only the values 0 or 1) or an int?

Regards,
Tom
