I have installed Markdown syntax plugin.
When I'm on a new buffer not associated with any file, and paste the source portion of the site http://rosylilly.github.com/markdown.html into it, the colors appear nicely as it should for the markdown syntax.
However, after saving the file, the colors change. Any idea how I can fix this?
Can you, before and after saving do
:verbose set filetype
:verbose set
Tip: use :redir > file.txt to capture the output so you won't have to copy/paste which can be difficult with gvim - for command output
You could also look at the autocommands when saving:
:verbose au BufWrite
:verbose au BufWritePre
:verbose au BufWritePost
This would serve to discover what plugin/script is causing the highlighting to go haywire.

I tried spell check for text file by adding this to my vimrc
augroup set_spell
autocmd!
autocmd FileType text :setlocal spell spelllang=en_us
augroup END
nnoremap <F10> :setlocal spell! spelllang=en_us<CR>
And it did not work
I tried :set spell and nothing happened
For some reasons, when I ran :source $MYVIMRC (still in that window), it worked. Though I can add sourcing command to my vimrc but I don't like the glitchy feeling of it.
What am I supposed to do?
Edit: I have found the solution
It's the problem with this vim rainbow plugin
https://github.com/frazrepo/vim-rainbow
So I uninstall that one and install this instead https://github.com/luochen1990/rainbow
Open the file and immediately do a :set ft? and :set spell?. Make sure they return text and spell respectively. If text is not returned, then the filetype is not being detected. If text is returned but spell is not, then the autocommand is not working.
Additionally, you should wrap autcommands in an augroup. See :h autocmd-groups. It might look like this:
augroup set_spell
autocmd!
autocmd FileType text setlocal spell
augroup END
Because this is a FileType autocommand, you are probably better off skipping the augroup and autocommands altogether and just putting the line setlocal spell in an ftplugin file. It would normally go in ~/vim/ftplugin/text.vim.
As a more general solution: Sometimes theme plugins overwrite SpellBad highlight group(It's one those gui vs terminal problems). Even though spell check works it just doesn't highlight. Without deleting your theme you can just add more style to the SpellBad highlight group as you wish:
Simply add this to your .vimrc:
"underline spell errors in terminals
hi SpellBad cterm=underline
or any other style really:
hi SpellBad ctermfg=Cyan cterm=bold
Be warned, these do not overwrite all existing styles. To truly overwriting it you may need to use hi clear SpellBad first.
See :h highlight for all the details. For the other Spell groups see :h hl-SpellBad.
I'm trying to disable syntax for Markdown files using autocmd in Vim. I have the following in my .vimrc:
function! SyntaxOff()
echom "one"
syntax off
echom "two"
endfunction
autocmd filetype markdown exe "call SyntaxOff()"
When I open a Markdown file and check :messages, I can see the one and two, and yet the syntax is still on. If I open a dummy file and subsequently open a Markdown file, then I can see that syntax is disabled. If I then open a file of a different filetype, then syntax is still disabled. My guess is that something else in my .vimrc is re-enabling the syntax when I open Vim up for the first time, but then after the function runs syntax is permanently shut off.
So my questions are (1) How can I disable syntax for Markdown files when I open them directly (i.e. not using the maneuver described above)? (2) How can I get Vim to re-enable syntax when I then open another file of a different filetype?
You should wrap your auto commands in a check and also in a group or else you will set multiple auto commands (resource leak) and Vim will slow down after a long time of use. It's also better to use FileTypes instead of regular expressions/matchers for auto commands. However, in some cases the regular expressions make sense. In this case I think you want to use a regex to match *.md as well as markdown files because Vim doesn't detect *.md as markdown.
if has("autocmd")
augroup standard
autocmd!
autocmd BufNewFile,BufRead *.markdown,*.md setlocal setfiletype disabled
augroup END
endif
#kev's answer shows you how to disable the Markdown filetype completely by modifying the filetype detection.
If you want to keep the filetype and indent plugins, and just disable the syntax, you can either:
turn off after-the-fact
Create ~/.vim/after/syntax/markdown.vim with:
setlocal syntax=
avoid turning on
Create ~/.vim/syntax/markdown.vim with:
if exists("b:current_syntax")
finish
endif
let b:current_syntax = "markdown"
I use Vim 7.3, and have this in my .vimrc (and nothing else):
filetype plugin indent on
autocmd FileType java :setlocal sw=4 ts=4 sts=2 noet
autocmd BufNewFile,BufReadPost ~/testdir/* setlocal sw=2 ts=2 sts=2 et
I have a directory ~/testdir which only contains a subdirectory p and the file ~/testdir/p/A.java which contains this:
class A {
}
If I open A.java by saying :e ~/testdir/p/A.java then :set et? reports that expandtab is currently ON.
On the other hand, if I start a new instance of Vim and go :vim A ~/testdir/** then this search will open A.java, but now :set et? tells me expandtab is OFF.
How do I make my intended indentation settings always apply for files under ~/testdir/?
The event BufReadPost should be being fired. Check that writing a message. This is:
autocmd BufNewFile,BufReadPost $HOME/git/repo/* echom "Reading buffer " . expand("<afile>")
Look for the messages with:
:messages
If the messages are there, then you know you are setting those options for the buffer. So, if the options have changed when the buffer is displayed, perhaps a plugin is setting them to some other thing. Check who is the culprit by showing who last changed the option with
:verbose set sw?
If that doesn't lead you to a solution, try using BufWinEnter instead of BufReadPost. That would probably work.
Vim explicitly recommends using ~ for the user home.
The help at :h autocmd-patterns says that you can use environment variables in the event patterns ...
... [a]nd ~ can be used for the home directory (if $HOME is defined):
:autocmd BufWritePost ~/.vimrc so ~/.vimrc
:autocmd BufRead ~archive/* set readonly
The environment variable is expanded when the autocommand is defined, not when
the autocommand is executed. This is different from the command!
So, change $HOME to ~ in your autocommand.
Even if your problem turns out to be unrelated it's good to follow the practice recommended in the docs.
The autocmd does work but probably not the way you expect since you did not set softtabstop.
autocmd BufNewFile,BufReadPost ~/git/repo/* setlocal sw=2 ts=2 sts=2 et
If you do not set softtabstop it will keep its old value. If this value is not 0 (which seems to be the case) when you press tab you will get the number of softtabstop spaces inserted into the file. And it will look like its not working.
It is generally a good idea to set shiftwidth, tabstop, and softtabstop to the same value if you ever change it.
Its also probably a good idea to make the set command local to the buffer by using setlocal.
Take a look at :h softtabstop
You can see that the autocmd "works" when softtabstop is set to its default value (of 0) if you run the command like this. And then run your :vim command
vim -u NONE -N -c'autocmd BufNewFile,BufReadPost $HOME/git/repo/* set sw=2 ts=2 et'
If I have an apache file in /etc/apache2/sites-available/www.example.com and I set its filetype like so
:set filetype=apache
What does that do? Does that change the file at all? Is it only reflected in the instance of vim? The session of vim? I can manually set the filetype, but then vim warns me that I am in read only mode (/etc/apache2 needs root access). If I open vim as root, I won't get the warning, but if I leave and open it again (as normal or root), the filetype is gone. How do I make this more permanent, at least when called from the same session file
set filetype changes the way vim handles the file, by invoking all the FileType autocommands. It does not persist. If you want to always open that file with filetype=apache, try adding this into your .vimrc:
au BufRead,BufNewFile /etc/apache2/sites-available/www.example.com set filetype=apache
You can read more about it in:
:help 'filetype'
:help filetypes
:help :autocmd
:help .vimrc
EDIT: as found in my /usr/share/vim/vim73/filetype.vim:
au BufNewFile,BufRead access.conf*,apache.conf*,apache2.conf*,httpd.conf*,srm.conf* call s:StarSetf('apache')
au BufNewFile,BufRead */etc/apache2/*.conf*,*/etc/apache2/conf.*/*,*/etc/apache2/mods-*/*,*/etc/apache2/sites-*/*,*/etc/httpd/conf.d/*.conf* call s:StarSetf('apache')
s:StarSetf will setfiletype to apache if the filetype doesn't match an ignored pattern. On my system, :echo g:ft_ignore_pat will show only archive file extensions as ignored. setfiletype does set filetype, but only once.
So, at least on my system, the pattern */etc/apache2/sites-*/* would catch your filename and make it an apache file.
The filetype basically lets Vim change settings for 'types of files'. The way it does this is by firing auto command for the FileType category when you change the filetype. This could potentially change your file if an auto command for FileType is applicable for your file (but generally plugin developers use it for r/o type changes that affect highlighting, and not the contents of the file).
If you are worried that setting the filetype is mucking with your file you can see what FileType autocommands exist by issuing the following command:
:au FileType
To setup your apache files to be apache filetypes you can put something like the following into your ~/.vimrc:
:au BufRead /etc/apache2/sites-available/* set ft=apache
I turned on filetype plugin for some rails vim plugins I added, but a side effect of this seems to be that now autocommenting has been enabled in all filetypes (for instance, if I start a line with #, the next line, either by Enter in insert mode or O, etc. to enter insert mode, will also get a #).
I found a guide to disabling the auto-commenting formatoptions, and added the following to my .vimrc:
au FileType * setlocal formatoptions-=cro
However, I am still running into problems -- unless I explicitly :source .vimrc, (or enter the setlocal ... directly), it is not taking effect. I determined that this is the case because vim's ftplugins are overriding my options with their own.
I then found a second guide which talks about using an after ftplugin script to make changes after the ftplugin scripts have run, however their solution is to create symlinks for every single filetype in ~/.vim/after/ftplugin to a central file, and this seems to be kludgy to me.
Is there any way to create a generic after-ftplugin script or am I approaching this problem incorrectly? Any help would be appreciated.
How about an "after" plugin? Create a file in ~/.vim/after/plugin/ called noAutoComments.vim (or whatever) and place your autocmd in that?
Edit:
The reason this works? I'm only guessing here, but I have a feeling that the autocmd in the ~/.vimrc file is getting removed by some other file (but before the "after" files are getting sourced).
I ended up removing my ~/.vim directory and replaced my ~/.vimrc with the following 3 lines:
filetype plugin on
syntax on
au FileType * setlocal formatoptions-=cro
With only these lines in my ~/.vimrc and no ~/.vim/ directory, the autocmd seems to work as expected (Vim 7.1).
For any file that I edit:
:verbose set formatoptions?
formatoptions=ql
Last set from ~/.vimrc
I have yet to determine what file (plugin) is causing this issue however.
I've done some more investigation and it seems that the location of my autocmd within my .vimrc file determines if formatoptions will be overridden by vim's ftplugins or not. Using vim --noplugin to disable all external plugins, I found the following results:
If my vimrc looks like:
au FileType * setl fo-=cro
filetype plugin indent on
The result of :verbose set fo? is:
formatoptions=croql
Last set from /usr/share/vim/vim72/ftplugin/ruby.vim
However, if the lines in my vimrc are reversed:
filetype plugin indent on
au FileType * setl fo-=cro
The result of :verbose set fo? is:
formatoptions=ql
Last set from ~/.vimrc
... which is the desired result. So it seems that the autocmd needs to be specified after filetype plugins are enabled.
Another reason this might not be taking effect...
From :he :set-=:
When the option is a list of flags, {value} must be
exactly as they appear in the option. Remove flags
one by one to avoid problems.
I have
" Turn off auto-commenting
au FileType * setlocal formatoptions-=c
au FileType * setlocal formatoptions-=r
au FileType * setlocal formatoptions-=o
because I've run into this.
Using one of the various autocmd events to set the configuration option should work if you find the right one, but I'd start by running:
:verbose set formatoptions?
This will tell you where the option was set, which may make it easier to determine which autocmd to use. Alternatively, if you don't mind a bit of minor hacking, the way I'd probably do it is just to find out where it's set in the plugin and comment out that line (and make a note of it in case you ever upgrade the plugin). You could also contact the plugin's author and ask them to make it a configurable option.
For the available autocmd events, read this:
:help {event}
I have tried solutions proposed by many, but none of them worked for me, but I found one very simple workaround, namely, in your ~/.bash_aliases:
# vim without auto comment
alias vi="vi +'set fo-=cro'"
I was struggling with this issue and I finally works with the following lines:
syntax on
filetype on
filetype plugin on
au FileType * setlocal formatoptions-=cro
I think the key here is that the autocmd is place after the filetype plugin on.
