How can I share my folds in VIM? - vim

I am in a project with 3 people. We need to have the same folds in Vim for each member. How can I share my folds?
[Feedback]
I understood one important thing: Google ignores signs, such as {{{, so please google "VIM three braces" to find help about the marker-method. It becomes much easier to practise, as you can quickly find relevant information.
In order to use the the marker-method (suggested by Adam Bellaire), please note that you have to set the method:
:set foldmethod=marker
Thanks for your answers!

Probably the easiest way is to just use fold markers (e.g. {{{1), making sure to include the vim:fdm=marker setting in the file itself. For example, here's a shell script which contains both the setting to use fold markers and two levels of fold:
#/bin/sh
# vim:fdm=marker
echo This file contains fold markers.
#Top Level Fold {{{1
echo This is a top-level fold.
#Second Level Fold {{{2
echo This is a second-level fold.
Opening this file in vim will show the first four lines and then a fold, which if expanded will reveal the second fold. Just make sure to put a space between your comment syntax and the vim:fdm=marker line or vim won't see it. For example, in C you could use:
// vim:fdm=marker

Folds in files ?
Well, same settings should result in same folds.
Vim can fold in several ways: manually, by indent, by expression, by syntax, and by markers (by default, I believe are curved brackets, 3 of them).
So if you have the same vim version, and they haven't changed their syntax and indent files, let them check out your vimrc for foldmethod and foldmarker options, and copy them to their vimrc files. That should do it.

I haven't shared VIM folds with someone before, but if you're working on the same machine perhaps you can use VIM sessions, which will save your current state (including folds). Run the following command in VIM:
mks! /path/to/session_file
Then your friend can load up the session file:
vim -s /path/to/session_file

Ancient history, I know, but this may have appeared since the version of vim present in '09, and since I don't have an adequate reputation to comment yet, here we go.
The good news is that saving a view for the file should save manual folds as well, even nested folds.
The bad news is that I found it didn't produce consistent results under vim 7.0 (RHEL 5.5). This may have been fixed in a subsequent update that, sad to say, we aren't allowed to install.

Vim folding breaks colorscheme [duplicate]

I'm using vim for LaTeX and I'm using latex-suite. It gives me nice syntax highlighting and folding, but in large files syntax highlighting gets "confused". If I open all folds, the syntax highlighting turns OK. I would like it to "just work" all the time though.
I seem to recall an option that would increase the number of lines that is used as basis for determining syntax highlighting but I cant find it.
I don't edit LaTeX, but perhaps you want ":syn sync fromstart"? Just be warned that this can significantly slow down Vim since it forces Vim to do syntax highlighting parsing for the whole file rather than a section of the file. See ::help :syn-sync".
Ctrl+L in normal mode forces a redraw and often fixes syntax colour problems.
zRzMzx (i.e., expand all folds, contract all folds, fold to show current line) sometimes fixes syntax highlighting problems related to folds
10 years later, this is still somehow an issue. Similarly as Jeromy, I suggest pressing zRzMzzza which stands for
open all folds
close all folds
open (toggle) the fold I'm on
center buffer on this line
It looks like we need to learn to live with this

How to autocomplete file paths in Vim, just like in zsh?

In Zsh, I can use filename completion with slashes to target a file deep in my source tree. For instance if I type:
vim s/w/t/u/f >TAB<
zsh replaces the pattern with:
vim src/wp-contents/themes/us/functions.php
What I'd like is to be able to target files the same way at the Vim command line, so that typing
:vi s/w/t/u/f >TAB<
will autocomplete to:
:vi src/wp-contents/themes/us/functions.php
I'm trying to parse the Vim docs for wildmode, but I don't see what settings would give me this. It's doing autocompletion for individual filenames, but not file paths. Does Vim support this natively? Or how can I customize the autocomplete algorithm for files?
Thanks for any advice!
-mykle-
I couldn't find a plugin to do this, so I wrote one. It's called vim-zsh-path-completion. It does what you're looking for, although via <C-s> rather than <Tab>. You can use it with <Tab> for even more control over what matches, though.
It's got bugs, but for basic paths without spaces/special characters, it should work. I think it's useful enough in its current state to be helpful. I hope to iron out the bugs and clean up the code, but I figured I'd start soliciting feedback now.
Thanks for the idea!
Original (wrong) answer, but with some useful information about Vim's wildmode.
Put the following in your .vimrc:
set wildmenu
set wildmode=list:longest
That will complete to the longest unique match on <Tab>, including appending a / and descending into directories where appropriate. If there are multiple matches, it will show a list of matches for what you've entered so far. Then you can type more characters and <Tab> again to complete.
I prefer the following setting, which completes to the first unique match on <Tab>, and then pops up a menu if you hit <Tab> again, which you can navigate with the arrow keys and hit enter to select from:
set wildmode=list:longest,list:full
Check out :help wildmenu and :help wildmode. You might also want to set wildignore to a list of patterns to ignore when completing. I have mine as:
set wildignore=.git,*.swp,*/tmp/*
Vim doesn't have such a feature by default. The closest buil-in feature is the wildmenu/wildmode combo but it's still very different.
A quick look at the script section of vim.org didn't return anything but I didn't look too far: you should dig further. Maybe it's there, somewhere.
Did you try Command-T, LustyExplorer, FuzzyFinder, CtrlP or one of the many similar plugins?
I use CtrlP and fuzzy matching can be done on filepath or filename. When done on filepath, I can use the keysequence below to open src/wp-contents/themes/us/functions.php (assuming functions.php is the only file under us that starts with a f):
,f " my custom mapping for the :CtrlP command
swtuf<CR>
edit
In thinking about a possible solution I'm afraid I was a little myopic. I was focused on your exact requirements but Vim has cool tricks when it comes to opening files!
The :e[dit] command accepts two types of wildcards: * is like the * you would use in your shell and ** means "any subdirectory".
So it's entirely possible to do:
:e s*/w*/t*/u*/f*<Tab>
or something like:
:e **/us/f<Tab>
or even:
:e **/fun<Tab>
Combined with the wildmode settings in Jim's answer, I think you have got a pretty powerful file navigation tool, here.

Vim Code Folding for Scilab

I've just recently started to use the folding functionality of vim and it's very helpful for the languages that it works really well for.
My issue lies in the way vim comments out the fold markers in scilab code. It defaults to
/*{{{*/ and /*}}}*/
which works great in languages like C, but is not actually a comment in scilab. I get a multiplication error when i try to run the code.
I've tried adding
autocmd FileType scilab set fmr=//{{{,//}}}
to my .vimrc file which doesn't quite do what I'd like. It results in
/*//{{{*/ and /*//}}}*/
which are still not comments. The code "folds" fine but becomes unusable. I could set up a macro to replace every instance of "/*" with "//", but that could have unintended consequences when applied globally to a file.
So the question is: how can i setup vim fold markers comments for scilab files such that it will not render the file unusable?
You do not add the comments to 'foldmarker' itself, there's the 'commentstring' option that influences how Vim surrounds the fold markers (when creating folds with zf). Try setting
:setlocal commentstring=//%s
for your scilab filetype. (Put the command in ~/.vim/after/ftplugin/scilab.vim to make it permanent.)
It sounds to me like vim doesn't understand how SciLab comments work. I'm not sure if vim comes with SciLab syntax logic these days, is syntax highlighted correctly in your SciLab files? If not, you can get the syntax file from here.
Is there a particular reason you want to use marks? They aren't actually needed. If you don't want vim to auto-fold by syntax or indentation level, you can still manually define folds with
:set foldmethod=manual
That lets you select a chunk of text in visual mode and make it into a fold with 'zf'. No marks required.

Configure tab to show list of variants instead of cycling through in VIM

When opening new buffer it VIM, I type:
new /path/to/fi
If I hit "tab" at this point it cycles through files. How to configure VIM to show list of variants instead of going for the first one?
set wildmenu
Is all you need to add to your .vimrc. Read :help wildmenu.
Set your wildmode setting to something different, for example
set wildmode=list:longest
If I misunderstood the question completely, yell ... :)
(This is not a direct answer to your question, but I think it's even better :)
You should check out the Command-T plugin, inspired by TextMate's 'Go To File'. It filters out possible combinations very intelligently, just type a few characters of each subdirectory enough to distinguish it and it 'gets' it, the characters don't have to be at the beginning and can don't have to be sequential. It also shows you a list of options left.
I realize this is a terrible explanation so check out this video to see how it works.
The downside is it requires Vim to be compiled with Ruby support.
Control-P (ctrlp.vim) is a replacement for Command-T written in VimScript, so it doesn't require Ruby.

Is vim able to detect the natural language of a file, then load the correct dictionary?

I am using several languages, and currently I am obliged to indicate to vim with which of these the spell check must be done. Is there a way to set up vim so that it automatically detects the correct one? I vaguely remember that in a previous version of vim, when the spell check was not integrated, the vimspell script made this possible.
It would be even better if this could apply not only to a file but also to a portion of a file, since I frequently mix several languages in a single file. Of course, I would like to avoid to load several dictionaries simultaneously.
I don't know if there is a way to autodetect it, but if you put vim:spell:spelllang=foo,bar,baz at the bottom of the file, vim will set the spellchecking languages to foo, bar, and baz when the file is opened. Note that you must put at least one space before that text, or vim will think it's part of the file.
Since vim is missing this feature, I found it useful to define shortcuts like these in .vimrc:
command! Nb :set spelllang=nb
command! En :set spelllang=en
