Auto insert text at a newline in vim

Question

I am editing a LaTeX file with vim. When I am in the \begin{itemize} environment, is there any way to tell vim to autoinsert \item whenever I open a new line?

Answer 1

function CR()
    if searchpair('\\begin{itemize}', '', '\\end{itemize}', '')
        return "\r\\item"
    endif
    return "\r"
endfunction
inoremap <expr><buffer> <CR> CR()

Put this into your .vim/ftplugins/tex.vim file (or any .vim inside .vim/ftplugins/tex directory).
