问题
I have a correctly formatted xml file, and following the command given as an answer here:
How can I autoformat/indent C code in vim?
I am trying to auto indent my file to display correct nesting.
Before I tried to use this command I set the file type to xml using :set ft=xml
as the file I started with has an extension of .mm, and also :set nowrap.
Here is my ~/.vimrc file:
syntax on
set history=1000
set smartindent
set tabstop=2
set shiftwidth=2
set expandtab
How come when I issue gg=G, I get a message saying 54 lines indented, yet my file remains un-nested?
回答1:
in case you wanna try Vim's own XML indenter thing, you can...
:filetype indent on (load indent files for specific file types etc.)
:e (to reload the current buffer)
this will load the vimscript at $VIMRUNTIME/indent/xml.vim
then when you do
:set indentexpr?
...it'll say indentexpr=XmlIndentGet(v:lnum, 1)

xmllint is better though, see... http://vim.wikia.com/wiki/VimTip349
i have handy keybinding like this for it in my .vimrc!
" one or more lines:
vmap ,px !xmllint --format -<CR>
" pretty-print current line
nmap ,px !!xmllint --format -<CR>

Try typing: :set equalprg?. If it says equalprg= it means that you do not have a program set for xml indentation, so it's probably doing some dumb default action. Here's a guide for setting xmllint as your formatter: http://ku1ik.com/2011/09/08/formatting-xml-in-vim-with-indent-command.html
