1" Vim support file to detect file types in scripts 2" 3" Maintainer: Bram Moolenaar <[email protected]> 4" Last change: 2020 Mar 06 5 6" This file is called by an autocommand for every file that has just been 7" loaded into a buffer. It checks if the type of file can be recognized by 8" the file contents. The autocommand is in $VIMRUNTIME/filetype.vim. 9" 10" Note that the pattern matches are done with =~# to avoid the value of the 11" 'ignorecase' option making a difference.
