Set vim file type for files without extension, only

How to configure file type and / or syntax for files that do not have a vim extension?

Note

This is a duplicate of the default vim syntax for files without an extension . I ask again, because no one answered it correctly, in my opinion.

I don’t want to know how to set the default syntax for unrecognized file types, I want to know how to set it only for files without extension.

You can create an autocommand that checks if the file name contains ., and if not, switches to the specified syntax:

autocmd BufNewFile,BufRead * if expand('%:t') !~ '\.' | set syntax=perl | endif

perl , , .

1) Hit escape to make sure you're in normal mode
2) Type ":set syntax=java" (or equivalent language)
3) :set filetype=FILETYPE, where FILETYPE is the filetype.

, :

autocmd BufNewFile,BufRead * if expand('%:t') !~ '\.' | set syntax=perl | endif

:help ftdetect vim , .

:

~/.vim/ftdetect, , . myfiletype.vim.

au BufRead,BufNewFile * if expand('<afile>:e') == '' | set ft=myfiletype | end

, vim myfiletype. , , , setfiletype myfiletype set ft=myfiletype.

~/.vim/syntax/myfiletype.vim. vim, . , autocommand myfiletype.

au BufRead,BufNewFile * if expand('<afile>:e') == '' | set ft=html | end

html, html.

In the end, I chose this for my C ++ configuration:

let s:reserved = '^NERD_tree\|^GoToFile$'
au BufNewFile,BufRead *
\ if expand('%:e') =~ '^\(h\|hh\|hxx\|hpp\|ii\|ixx\|ipp\|inl\|txx\|tpp\|tpl\|cc\|cxx\|cpp\)$' ||
\    expand('%:t') !~ '\.\|'.s:reserved && expand('%:t') =~ '[a-z]'                            |
\   if &ft != 'cpp'                                                                            |
\     set ft=cpp                                                                               |
\   endif                                                                                      |
\   set syntax=cpp11                                                                           |
\   call CSyntaxAfter()                                                                        |
\ endif

Instead of checking for a missing .tail. This avoids the fact that several cpp files will not be installed as the COMMIT_EDITMSG, README, GoToFilefrom CommandT and NERD_tree*from NERD tree.

EDIT

I just gave up this idea.
