Can I tell vim to assume a filename ends in .tex if no extension is given? e.g. to open bird.tex if I say :e bird (unless there is a file bird with no extension).

3Related: vi.stackexchange.com/q/239/205 - you can probably adapt one of those to use a check for extensions (or lack thereof) instead of checking the directory. – muru Feb 24 '16 at 18:56

Adapting tricks I got from two of my previous questions, this should work:
function! EditTex(name)
if a:name !~ '\.[^/]*$'
setlocal bufhidden=wipe
exe 'e' fnameescape(a:name).'.tex'
set bufhidden<
endif
endfunction
autocmd BufNewFile * nested call EditTex(expand('<afile>'))
The function checks if the filename has an extension, and if not, starts editing a TeX file with that name. Since a BufNewFile autocmd will only run for files that don't exist, we can avoid that check.
With this, you can run :e bird as you normally would.

There is a problem with this, it creates
bird.texif you typvi birdat the cmdline. – Toothrot Feb 27 '16 at 13:52 -
@Lawrence Is that a problem? I would have thought that expected behaviour. – muru Feb 27 '16 at 13:53

Oh, sorry, my q. wasn't quite clear. I wanted to open
bird.texunlessbirdexisted, but not create a texfile when neitherbirdnorbird.texexisted from before. When I think about it, maybe this was just a bad idea: I also want to be able to createbirdeven thoughbird,texexists. Sorry! – Toothrot Feb 27 '16 at 14:00 -

Maybe you could try the following custom command :E :
command! -nargs=1 -complete=file E
\ let s:file = fnamemodify('<args>', ':p') |
\ if fnamemodify(s:file, ':e') ==# '' && !filereadable(s:file) |
\ edit <args>.tex |
\ else |
\ edit <args> |
\ endif |
\ unlet s:file
It checks if the filename given as an argument has no extension if it doesn't exist. In this case, it executes :edit {argument}.tex, otherwise it executes :edit {argument}.
So if you type: :E bird it should load a buffer whose name is bird.tex unless a file named bird already exists.
