RE: File type detection.

Hi Gary,

Thanks for the answer. I made couple of tests and this is what I found out.

It works perfect when I run "vim -N -u NONE" as you did.
When I run "vim -N --noplugin" there are some things I do not understand.

Test 1: "vim -N --noplugin" (no ~/.vimrc and no ~/.vim/filetype.vim)
:set rtp?

runtimepath=~/.vim,/usr/share/vim/vimfiles,/usr/share/vim/vim74,/usr/share/v
im/vimfiles/after,~/.vim/after
:scriptnames
1: /etc/vimrc
2: /usr/share/vim/vim74/syntax/syntax.vim
3: /usr/share/vim/vim74/syntax/synload.vim
4: /usr/share/vim/vim74/syntax/syncolor.vim
5: /usr/share/vim/vim74/filetype.vim
6: /usr/share/vim/vim74/ftplugin.vim

Why does VIM load /etc/vimrc if the directory is not in rtp?

Test 2: "vim -N --noplugin" (without ~/.vimrc, with ~/.vim/filetype.vim)
:set rtp?

runtimepath=~/.vim,/usr/share/vim/vimfiles,/usr/share/vim/vim74,/usr/share/v
im/vimfiles/after,~/.vim/after
:scriptnames
1: /etc/vimrc
2: /usr/share/vim/vim74/syntax/syntax.vim
3: /usr/share/vim/vim74/syntax/synload.vim
4: /usr/share/vim/vim74/syntax/syncolor.vim
5: ~/.vim/filetype.vim
6: /usr/share/vim/vim74/filetype.vim
7: /usr/share/vim/vim74/ftplugin.vim

Good ~/.vim/filetype.vim is before /usr/share/vim/vim74/filetype.vim like in
rtp list.

But I want to put my filetype outside my home directory, in test I used my
desktop.

Test 3: "vim -N --noplugin: (with ~/.vimrc (one line to change rtp), with
~/.vim/filetype.vim)
:set rtp?

runtimepath=~/Desktop,~/.vim,/usr/share/vim/vimfiles,/usr/share/vim/vim74,/u
sr/share/vim/vimfiles/after,~/.vim/after
:filetype on
:scriptnames
1: /etc/vimrc
2: /usr/share/vim/vim74/syntax/syntax.vim
3: /usr/share/vim/vim74/syntax/synload.vim
4: /usr/share/vim/vim74/syntax/syncolor.vim
5: ~/.vim/filetype.vim
6: /usr/share/vim/vim74/filetype.vim
7: /usr/share/vim/vim74/ftplugin.vim
8: ~/.vimrc
9: ~/Desktop/filetype.vim

Here I can see that filetype.vim from desktop is last but base on rtp it
should be first.

It looks like VIM does not load ~/Desktop/filetype.vim at the beginning
since rtp is updated with ~/.vimrc at point 7.

I am pretty sure all problems are made because /etc/vimrc. I do not
understand why VIM loads that file.
Right now I not able to touch that file since I have no permission (this is
computer at work).

Regards,
Bartosz

Yes, it does. I have modified my 'rtp' in my ~/.vimrc and Vim sources
scripts in the order specifed by the modified 'rtp'.

You shouldn't have to change anything to get Vim to source your filetype.vim
first. I have my own filetype.vim and as you can see here, it is sourced
first.

$ vim -N -u NONE
:filetype on
:scriptnames
1: ~/.vim/filetype.vim
2: /usr/local/share/vim/vim74/filetype.vim

Gary
