Storing vim settings with a document
VimSettingsVim Problem Overview
Is there any way to save the state of vim settings with a document?
To clarify: I'm editing a document and I change a bunch of settings. I don't necessarily recall which; and I don't want to use these settings again, except for the current document. I don't want to manually try to remember what I've changed; or what the magic abbreviations are for the settings I've changed. I just want to have, say, for "mydoc.txt", a "mydoc.vim" file that puts me back where I left off, and the settings file would be saved automatically based on a vim setting, say, or maybe a ctrl-key does it before I exit. It would be handy if vim could automatically look for such a file.
And it would be preferable not to have to edit the settings into and out of the document itself.
Vim Solutions
Solution 1 - Vim
Yes, vim settings can be included within the document.
They are mostly found within comments, so they don't mess up the original file. An example for tab-specific settings is:
/* ex: set tabstop=8 expandtab: */
Note that this command works in most cases, however, servers are often setup without modeline turned on for security reasons. To turn on that feature add the following in your $HOME/.vimrc or the system $VIM/vimrc:
set modeline
Solution 2 - Vim
You can use Vim's Session support:
:mksession
you can later load this by either running vim -S Session.vim, or using source Session.vim
There are also vim addons to automate session loading/saving
Solution 3 - Vim
Here's how you save all your current settings to a file:
:redir > textfile.txt
:set all
:redir END
If you like, just rename that file to ~/.vimrc and away you go.
Solution 4 - Vim
You can save your settings globally by editing your .vimrc file.
Vim also lets you save settings per file by using modelines
Solution 5 - Vim
You could maybe save the file as a particular type, e.g. special filename format or extension, and then define an autocommand in your .vimrc for that filetype.
I do this for my makefiles to ensure that I have the various settings I need for specific files.
For example, here's my autocommand dec.
if has("autocmd")
autocmd BufRead,BufNewFile Makefile* :set noexpandtab
autocmd BufRead,BufNewFile mirror.conf :set noexpandtab
autocmd BufRead,BufNewFile *.html* :set shiftwidth=2
autocmd BufRead,BufNewFile diff_files :set autowrite
autocmd BufRead,BufNewFile lbnamed* :set ft=perl
autocmd BufRead,BufNewFile *.t :set ft=perl
endif
