vimrc-语法突出显示不起作用

Question

so this is what my .vimrc contains, why is my syntax highlighting not working?

set nocompatible " must be the first line
filetype plugin indent on
syntax on
set laststatus=2
set statusline=%<%f\%h%m%r%=%-20.(line=%l\ \ col=%c%V\ \ totlin=%L%)\ \ \%h%m%r%=%-40(bytval=0x%B,%n%Y%)\%P
set nu
set shortmess=I
set nowrap
set tabstop=2
set backspace=indent,eol,start
set shiftwidth=2
set shiftround
set ignorecase
set smarttab
set hlsearch
set incsearch
set undolevels=1000
set pastetoggle=<F2>
set t_Co=256
colorscheme monokai
let g:user_emmet_leader_key = '<c-y>'
execute pathogen#infect()
autocmd StdinReadPre * let s:std_in=1
autocmd VimEnter * if argc() == 0 && !exists("s:std_in") | NERDTree | endif
autocmd vimenter * NERDTree

My color theme works, but the colors are not showing up properly as syntax highlighting.

Any suggestions?

Answer 1

First, check the output of:

:setlocal syntax?

The correct output (for php files) is:

syntax=php

You can check the php syntax code doing a:

:syntax list

You must see all syntax code with the command above. If you don't get the syntax=php value or don't see any syntax code on :syntax list , probably you don't have a php.vim file in your ~/.vim/ftplugin folder. When you set filetype plugin on and open an php file, what Vim does is to look in your ftplugin folder for a php.vim file and execute it.

php.vim is a system file, and it comes with the default installation. Try to do a :scriptname to see all scripts that are opening with vim. If you can't see a php.vim file, a solution could be install StanAngeloff/php.vim plugin.

If, and only if, you have a php.vim file and see its syntax with :syntax list , then something external is affecting Vim's syntax highlight, and it's probably your terminal.
