plugin works if opening a file from command line, doesn't work if opening a file from vim

Hi Andrew,

First of all, many thanks for your effort building and maintaining this project.

I've played a bit a few months ago and just came back to it and realized that is not working if I open a file from vim.

1. I start vim in my terminal and open a file from vim using :e /path/to/file

• this case Switch plugin won't work - eg. not changing 'foo' to 'bar', seemingly has no effect at all

2. I start vim in my terminal passing /path/to/file as an argument vim /path/to/file

• Switch plugin works as intended

I tried with this minimal 4 lines .vimrc

     call plug#begin('~/.vim/plugged')
        Plug 'AndrewRadev/switch.vim'
     call plug#end()
       let b:switch_custom_definitions = [ ['foo', 'bar', 'baz'] ]

Thanks,
Szilveszter

I've found if I am using
let g:switch_custom_definitions
instead of
let b:switch_custom_definitions in my .vimrc
then Switch works fine even if I open the file from vim.

I think I understand the problem. The custom definitions you've created with b:switch_custom_definitions are buffer-local. That's what the b: prefix means. You can find more information on the topic with :help b:.

Basically, if you wanted to only define switches for a particular filetype, you would use the b: variant. I guess I hadn't explained it well enough in the documentation, so I added some more information about it:

switch.vim/doc/switch.txt

Lines 162 to 170 in f982683

	Use the `g:` version of the variable for global definitions, and the `b:`
	version for specific filetypes. For instance, here is how you would define
	switches only for ruby:
	>
	autocmd FileType ruby let b:switch_custom_definitions =
	\ [
	\ ...
	\ ]
	<

Does this solve your issue?

Yes, that is perfect. Thanks a lot!
