*netrw-hiding* {{{2

Netrw's browsing facility allows one to use the hiding list in one of three
ways: ignore it, hide files which match, and show only those files which
match.

If no files have been marked via |netrw-mf|:

The "a" map allows the user to cycle through the three hiding modes.

The |g:netrw_list_hide| variable holds a comma delimited list of patterns
based on regular expressions (ex. ^.*\.obj$,^\.) which specify the hiding list.
(also see |netrw-ctrl-h|)  To set the hiding list, use the <c-h> map.  As an
example, to hide files which begin with a ".", one may use the <c-h> map to
set the hiding list to '^\..*' (or one may put let g:netrw_list_hide= '^\..*'
in one's <.vimrc>).  One may then use the "a" key to show all files, hide
matching files, or to show only the matching files.

	Example: \.[ch]$
		This hiding list command will hide/show all *.c and *.h files.

	Example: \.c$,\.h$
		This hiding list command will also hide/show all *.c and *.h
		files.

Don't forget to use the "a" map to select the mode (normal/hiding/show) you
want!

If files have been marked using |netrw-mf|, then this command will:

  if showing all files or non-hidden files:
   modify the g:netrw_list_hide list by appending the marked files to it
   and showing only non-hidden files.

  else if showing hidden files only:
   modify the g:netrw_list_hide list by removing the marked files from it
   and showing only non-hidden files.
  endif

As a quick shortcut, one may press >
	gh
to toggle between hiding files which begin with a period (dot) and not hiding
them.

					*netrw-gitignore*
Netrw provides a helper function 'netrw_gitignore#Hide()' that, when used with
|g:netrw_list_hide| automatically hides all git-ignored files.

'netrw_gitignore#Hide' searches for patterns in the following files: >

	'./.gitignore'
	'./.git/info/exclude'
	global gitignore file: `git config --global core.excludesfile`
	system gitignore file: `git config --system core.excludesfile`
<
Files that do not exist, are ignored.
Git-ignore patterns are taken from existing files, and converted to patterns for
hiding files. For example, if you had '*.log' in your '.gitignore' file, it
would be converted to '.*\.log'.

To use this function, simply assign its output to |g:netrw_list_hide| option.  >

	Example: let g:netrw_list_hide= netrw_gitignore#Hide()
		Git-ignored files are hidden in Netrw.

	Example: let g:netrw_list_hide= netrw_gitignore#Hide('my_gitignore_file')
		Function can take additional files with git-ignore patterns.

	Example: let g:netrw_list_hide= netrw_gitignore#Hide() .. '.*\.swp$'
		Combining 'netrw_gitignore#Hide' with custom patterns.

Especially with the remote directory browser, constantly entering the password
is tedious.

For Linux/Unix systems, the book "Linux Server Hacks - 100 industrial strength
tips & tools" by Rob Flickenger (O'Reilly, ISBN 0-596-00461-3) gives a tip
for setting up no-password ssh and scp and discusses associated security
issues.  It used to be available at http://hacks.oreilly.com/pub/h/66 ,
but apparently that address is now being redirected to some "hackzine".
I'll attempt a summary based on that article and on a communication from
Ben Schmidt:

	1. Generate a public/private key pair on the local machine
	   (ssh client): >
		ssh-keygen -t rsa
		(saving the file in ~/.ssh/id_rsa as prompted)
<
	2. Just hit the <CR> when asked for passphrase (twice) for no
	   passphrase.  If you do use a passphrase, you will also need to use
	   ssh-agent so you only have to type the passphrase once per session.
	   If you don't use a passphrase, simply logging onto your local
	   computer or getting access to the keyfile in any way will suffice
	   to access any ssh servers which have that key authorized for login.
