permission to remove a file, it will issue an error message.

CUSTOMIZING BROWSING WITH A SPECIAL HANDLER *netrw-x* *netrw-handler* {{{2
Certain files, such as html, gif, jpeg, (word/office) doc, etc, files, are
best seen with a special handler (ie. a tool provided with your computer's
operating system). Netrw allows one to invoke such special handlers by: >
operating system). Netrw allows one to invoke such special handlers by:
* when Exploring, hit the "x" key
* when editing, hit gx with the cursor atop the special filename
< (latter not available if the |g:netrw_nogx| variable exists)
* hitting gx with the cursor atop the file path or alternatively x
in a netrw buffer; the former can be disabled by defining the
|g:netrw_nogx| variable
* when in command line, typing :Open <path>, see |:Open| below.
Netrw determines which special handler by the following method:
* if |g:netrw_browsex_viewer| exists, then it will be used to attempt to
view files. Examples of useful settings (place into your <.vimrc>): >
:let g:netrw_browsex_viewer= "kfmclient exec"
< or >
:let g:netrw_browsex_viewer= "xdg-open"
<
If the viewer you wish to use does not support handling of a remote URL
directory, set |g:netrw_browsex_support_remote| to 0.
* for Windows 32 or 64, the URL and FileProtocolHandler dlls are used.
* for Gnome (with gnome-open): gnome-open is used.
* for KDE (with kfmclient) : kfmclient is used
* for Mac OS X : open is used.
The gx mapping extends to all buffers; apply "gx" while atop a word and netrw
will apply a special handler to it (like "x" works when in a netrw buffer).
One may also use visual mode (see |visual-start|) to select the text that the
special handler will use. Normally gx uses expand("<cfile>") to pick up the
text under the cursor; one may change what |expand()| uses via the
special handler will use. Normally gx checks for a close-by URL or file name
to pick up the text under the cursor; one may change what |expand()| uses via the
|g:netrw_gx| variable (options include "<cword>", "<cWORD>"). Note that
expand("<cfile>") depends on the |'isfname'| setting. Alternatively, one may
select the text to be used by gx by making a visual selection (see
|visual-block|) and then pressing gx.
The selection function can be adapted for each filetype by adding a function
`Netrw_get_URL_<filetype>`, where <filetype> is given by the 'filetype'.
The function should return the URL or file name to be used by gx, and will
fall back to the default behavior if it returns an empty string.
For example, special handlers for links Markdown and HTML are
" make gx work on concealed links regardless of exact cursor position: >
function Netrw_get_URL_markdown()
" markdown URL such as [link text](http://ya.ru 'yandex search')
try
let save_view = winsaveview()
if searchpair('\[.\{-}\](', '', ')\zs', 'cbW', '', line('.')) > 0
return matchstr(getline('.')[col('.')-1:],
\ '\[.\{-}\](\zs' .. g:netrw_regex_url .. '\ze\(\s\+.\{-}\)\?)')
endif
finally
call winrestview(save_view)
return ''
endtry
endfunction
function Netrw_get_URL_html()
" HTML URL such as <a href='http://www.python.org'>Python is here</a>
" <a href="http://www.python.org"/>
try
let save_view = winsaveview()
if searchpair('<a\s\+href=', '', '\%(</a>\|/>\)\zs', 'cbW', '', line('.')) > 0
return matchstr(getline('.')[col('.') - 1 : ],
\ 'href=["'.."'"..']\?\zs\S\{-}\ze["'.."'"..']\?/\?>')
endif
finally
call winrestview(save_view)
return ''
endtry
endfunction
<
Other than a file path, the text under the cursor may be a URL. Netrw uses
by default the following regular expression to determine if the text under the
cursor is a URL:
>
:let g:netrw_regex_url = '\%(\%(http\|ftp\|irc\)s\?\|file\)://\S\{-}'
<
Associated setting variables:
|g:netrw_gx| control how gx picks up the text under the cursor
|g:netrw_nogx| prevent gx map while editing
|g:netrw_suppress_gx_mesg| controls gx's suppression of browser messages
OPENING FILES AND LAUNCHING APPS *netrw-gx* *:Open* *:Launch* {{{2
Netrw determines which special handler by the following method:
* if |g:netrw_browsex_viewer| exists, then it will be used to attempt to
view files. Examples of useful settings (place into your <.vimrc>):
If the viewer you wish to use does not support handling of a remote URL
directory, set |g:netrw_browsex_support_remote| to 0.
* otherwise:
* for Windows : explorer.exe is used
* for Mac OS X : open is used.
* for Linux : xdg-open is used.
To open a path (or URL) <path> by the appropriate handler, type >
:Open <path>
<
No escaping, neither for the shell nor for Vim's command-line, is needed.
To launch a specific application <app> <args>, often <args> being <path> >
:Launch <app> <args>.
Since <args> can be arbitrarily complex, in particular contain many file
paths, the escaping is left to the user.
If you disabled the netrw plugin by setting g:loaded_netrwPlugin (see
|netrw-noload|), then you can use >
:call netrw#Launch('<app> <args>')
:call netrw#Open('<path>')
