Vim Question: Sparkup doesn't work for files opened from a running Vim session

Question

If I were to open a file with Vim from the command prompt (eg: vim ~/.vimrc), the Sparkup text generation seems to work perfectly fine. For example if I insert:

html:xs

and then push control + e, sparkup generates a nice HTML strict boilerplate. However if I then split to another file from the running Vim session, Sparkup stops working in the newly opened file. It's totally possible that other plugins lose their functionality as well. Here is my .vimrc file:

set nocompatible    " use vim defaults
set number          " show line numbers
set tags=tags;$HOME/.vim/tags/ "recursively searches directory for 'tags' file
set expandtab       " tabs are converted to spac
set tabstop=4       " numbers of spaces of tab character
set shiftwidth=4    " numbers of spaces to (auto)indent
set showcmd         " display incomplete commands
set incsearch       " do incremental searching
set ruler           " show the cursor position all the time
set numberwidth=4   " line numbering takes up 5 spaces
set ignorecase      " ignore case when searching
set nowrap          " stop lines from wrapping
set incsearch       " show search matches as you type

Answer 1

Can it be that this plugin is bound to a given FileType and that when you change window the FileType is not the same?

If it doesn't work, try adding your plugin to ftplugins.
