8Files can be found everywhere.  So how do you find them?  Vim offers various
9ways to browse the directory tree.  There are commands to jump to a file that
10is mentioned in another.  And Vim remembers which files have been edited
11before.

22==============================================================================
23*22.1*	The file browser
24
25Vim has a plugin that makes it possible to edit a directory.  Try this: >
26
27	:edit .
28
29Through the magic of autocommands and Vim scripts, the window will be filled
30with the contents of the directory.  It looks like this:
31
32" ============================================================================ ~
33" Netrw Directory Listing                                        (netrw v109) ~
34"   Sorted by      name ~
35"   Sort sequence: [\/]$,\.h$,\.c$,\.cpp$,*,\.info$,\.swp$,\.o$\.obj$,\.bak$ ~
36"   Quick Help: <F1>:help  -:go up dir  D:delete  R:rename  s:sort-by  x:exec ~
37" ============================================================================ ~
38../ ~
39./ ~
40check/ ~
41Makefile ~
42autocmd.txt ~
43change.txt ~
44eval.txt~ ~
45filetype.txt~ ~
46help.txt.info ~
47
48You can see these items:
49
501.  The name of the browsing tool and its version number
512.  The name of the browsing directory
523.  The method of sorting (may be by name, time, or size)
534.  How names are to be sorted (directories first, then *.h files,
54    *.c files, etc)
555.  How to get help (use the <F1> key), and an abbreviated listing
56    of available commands
576.  A listing of files, including "../", which allows one to list
58    the parent directory.
59
60If you have syntax highlighting enabled, the different parts are highlighted
61so as to make it easier to spot them.
62
63You can use Normal mode Vim commands to move around in the text.  For example,
64move the cursor atop a file and press <Enter>; you will then be editing that
65file.  To go back to the browser use ":edit ." again, or use ":Explore".
66CTRL-O also works.
67
68Try using <Enter> while the cursor is atop a directory name.  The result is
69that the file browser moves into that directory and displays the items found
70there.  Pressing <Enter> on the first directory "../" moves you one level
71higher.  Pressing "-" does the same thing, without the need to move to the
72"../" item first.
73
74You can press <F1> to get help on the things you can do in the netrw file
75browser.  This is what you get: >

98<    	(etc)
99
100The <F1> key thus brings you to a netrw directory browsing contents help page.
101It's a regular help page; use the usual |CTRL-]| to jump to tagged help items
102and |CTRL-O| to jump back.
103
104To select files for display and editing: (with the cursor is atop a filename)
105
106	<enter>		Open the file in the current window.	   |netrw-cr|
107	o		Horizontally split window and display file |netrw-o|
108	v		Vertically split window and display file   |netrw-v|
109	p		Use the |preview-window| 		   |netrw-p|
110	P		Edit in the previous window		   |netrw-P|
111	t		Open file in a new tab			   |netrw-t|
112
113The following normal-mode commands may be used to control the browser display:
114
115	i		Controls listing style (thin, long, wide, and tree).
116			The long listing includes size and date information.
117	s		Repeatedly pressing s will change the way the files
118			are sorted; one may sort on name, modification time,
119			or size.
120	r		Reverse the sorting order.
121
122As a sampling of extra normal-mode commands:
123
124	cd		Change Vim's notion of the current directory to be
125			the same as the browser directory.  (see
126			|g:netrw_keepdir| to control this, too)
127	R		Rename the file or directory under the cursor; a
128			prompt will be issued for the new name.
129	D		Delete the file or directory under the cursor; a
130			confirmation request will be issued.
131	mb gb		Make bookmark/goto bookmark
132
133
134One may also use command mode; again, just a sampling:
135
136	:Explore [directory]	Browse specified/current directory
137	:NetrwSettings		A comprehensive list of your current netrw
138				settings with help linkage.
139
140The netrw browser is not limited to just your local machine; one may use
141urls such as:    (that trailing / is important)
142
143	:Explore ftp://somehost/path/to/dir/
144	:e scp://somehost/path/to/dir/
145
146See |netrw-browse| for more.
147
148==============================================================================
149*22.2*	The current directory
150
151Just like the shell, Vim has the concept of a current directory.  Suppose you
152are in your home directory and want to edit several files in a directory
153"VeryLongFileName".  You could do: >
154
155	:edit VeryLongFileName/file1.txt
156	:edit VeryLongFileName/file2.txt
157	:edit VeryLongFileName/file3.txt
158
159To avoid much of the typing, do this: >
160
161	:cd VeryLongFileName
162	:edit file1.txt
163	:edit file2.txt
164	:edit file3.txt
165
166The ":cd" command changes the current directory.  You can see what the current
167directory is with the ":pwd" command: >
168
169	:pwd
170	/home/Bram/VeryLongFileName
171
172Vim remembers the last directory that you used.  Use "cd -" to go back to it.
173Example: >
174
175	:pwd
176	/home/Bram/VeryLongFileName
177	:cd /etc
178	:pwd
179	/etc
180	:cd -
181	:pwd
182	/home/Bram/VeryLongFileName
183	:cd -
184	:pwd
185	/etc
186
187
188WINDOW LOCAL DIRECTORY
189
190When you split a window, both windows use the same current directory.  When
191you want to edit a number of files somewhere else in the new window, you can
192make it use a different directory, without changing the current directory in
193the other window.  This is called a local directory. >
194
195	:pwd
196	/home/Bram/VeryLongFileName
197	:split
198	:lcd /etc
199	:pwd
200	/etc
201	CTRL-W w
202	:pwd
203	/home/Bram/VeryLongFileName
204
205So long as no `:lcd` command has been used, all windows share the same current
206directory.  Doing a `:cd` command in one window will also change the current
207directory of the other window.
208   For a window where `:lcd` has been used a different current directory is
209remembered.  Using `:cd` or `:lcd` in other windows will not change it.
210   When using a `:cd` command in a window that uses a different current
211directory, it will go back to using the shared directory.
212
213
214TAB LOCAL DIRECTORY
215
216When you open a new tab page, it uses the directory of the window in the
217previous tab page from which the new tab page was opened. You can change the
218directory of the current tab page using the `:tcd` command. All the windows in
219a tab page share this directory except for windows with a window-local
220directory. Any new windows opened in this tab page will use this directory as
221the current working directory. Using a `:cd` command in a tab page will not
222change the working directory of tab pages which have a tab local directory.
223When the global working directory is changed using the `:cd` command in a tab
224page, it will also change the current tab page working directory.
225
226
227==============================================================================
228*22.3*	Finding a file
229
230You are editing a C program that contains this line:
231
232	#include "inits.h" ~
233
234You want to see what is in that "inits.h" file.  Move the cursor on the name
235of the file and type: >
236
237	gf
238
239Vim will find the file and edit it.
240   What if the file is not in the current directory?  Vim will use the 'path'
241option to find the file.  This option is a list of directory names where to
242look for your file.
243   Suppose you have your include files located in "c:/prog/include".  This
244command will add it to the 'path' option: >
245
246	:set path+=c:/prog/include
247
248This directory is an absolute path.  No matter where you are, it will be the
249same place.  What if you have located files in a subdirectory, below where the
250file is?  Then you can specify a relative path name.  This starts with a dot:
251>
252	:set path+=./proto
253
254This tells Vim to look in the directory "proto", below the directory where the
255file in which you use "gf" is.  Thus using "gf" on "inits.h" will make Vim
256look for "proto/inits.h", starting in the directory of the file.
257   Without the "./", thus "proto", Vim would look in the "proto" directory
258below the current directory.  And the current directory might not be where the
259file that you are editing is located.
260
261The 'path' option allows specifying the directories where to search for files
262in many more ways.  See the help on the 'path' option.
263   The 'isfname' option is used to decide which characters are included in the
264file name, and which ones are not (e.g., the " character in the example
265above).
266
267When you know the file name, but it's not to be found in the file, you can
268type it: >
269
270	:find inits.h
271
272Vim will then use the 'path' option to try and locate the file.  This is the
273same as the ":edit" command, except for the use of 'path'.
274
275To open the found file in a new window use CTRL-W f instead of "gf", or use
276":sfind" instead of ":find".
277
278
279A nice way to directly start Vim to edit a file somewhere in the 'path': >
280
281	vim "+find stdio.h"
282
283This finds the file "stdio.h" in your value of 'path'.  The quotes are
284necessary to have one argument |-+c|.
285
286==============================================================================
287*22.4*	The buffer list
288
289The Vim editor uses the term buffer to describe a file being edited.
290Actually, a buffer is a copy of the file that you edit.  When you finish
291changing the buffer, you write the contents of the buffer to the file.
292Buffers not only contain file contents, but also all the marks, settings, and
293other stuff that goes with it.
294
295
296HIDDEN BUFFERS
297
298Suppose you are editing the file one.txt and need to edit the file two.txt.
299You could simply use ":edit two.txt", but since you made changes to one.txt
300that won't work.  You also don't want to write one.txt yet.  Vim has a
301solution for you: >
302
303	:hide edit two.txt
304
305The buffer "one.txt" disappears from the screen, but Vim still knows that you
306are editing this buffer, so it keeps the modified text.  This is called a
307hidden buffer: The buffer contains text, but you can't see it.
308   The argument of ":hide" is another command.  ":hide" makes that command
309behave as if the 'hidden' option was set.  You could also set this option
310yourself.  The effect is that when any buffer is abandoned, it becomes hidden.
311   Be careful!  When you have hidden buffers with changes, don't exit Vim
312without making sure you have saved all the buffers.
313
314
315INACTIVE BUFFERS
316
317   When a buffer has been used once, Vim remembers some information about it.
318When it is not displayed in a window and it is not hidden, it is still in the
319buffer list.  This is called an inactive buffer.  Overview:
320
321   Active		Appears in a window, text loaded.
322   Hidden		Not in a window, text loaded.
323   Inactive		Not in a window, no text loaded.
324
325The inactive buffers are remembered, because Vim keeps information about them,
326like marks.  And remembering the file name is useful too, so that you can see
327which files you have edited.  And edit them again.
328
329
330LISTING BUFFERS
331
332View the buffer list with this command: >
333
334	:buffers
335
336A command which does the same, is not so obvious to list buffers, but is much
337shorter to type: >
338
339	:ls
340
341The output could look like this:
342
343  1 #h   "help.txt"			line 62 ~
344  2 %a + "usr_21.txt"			line 1 ~
345  3      "usr_toc.txt"			line 1 ~
346
347The first column contains the buffer number.  You can use this to edit the
348buffer without having to type the name, see below.
349   After the buffer number come the flags.  Then the name of the file
350and the line number where the cursor was the last time.
351   The flags that can appear are these (from left to right):
352
353	u	Buffer is unlisted |unlisted-buffer|.
354	 %	Current buffer.
355	 #	Alternate buffer.
356	  a	Buffer is loaded and displayed.
357	  h	Buffer is loaded but hidden.
358	   =	Buffer is read-only.
359	   -	Buffer is not modifiable, the 'modifiable' option is off.
360	    +	Buffer has been modified.
361
362
363EDITING A BUFFER
364
365You can edit a buffer by its number.  That avoids having to type the file
366name: >
367
368	:buffer 2
369
370But the only way to know the number is by looking in the buffer list.  You can
371use the name, or part of it, instead: >
372
373	:buffer help
374
375Vim will find the best match for the name you type.  If there is only one
376buffer that matches the name, it will be used.  In this case "help.txt".
377   To open a buffer in a new window: >
378
379	:sbuffer 3
380
381This works with a name as well.
382
383
384USING THE BUFFER LIST
385
386You can move around in the buffer list with these commands:
387
388	:bnext		go to next buffer
389	:bprevious	go to previous buffer
390	:bfirst		go to the first buffer
391	:blast		go to the last buffer
392
393To remove a buffer from the list, use this command: >
394
395	:bdelete 3
396
397Again, this also works with a name.
398   If you delete a buffer that was active (visible in a window), that window
399will be closed.  If you delete the current buffer, the current window will be
400closed.  If it was the last window, Vim will find another buffer to edit.  You
401can't be editing nothing!
402
403	Note:
404	Even after removing the buffer with ":bdelete" Vim still remembers it.
405	It's actually made "unlisted", it no longer appears in the list from
406	":buffers".  The ":buffers!" command will list unlisted buffers (yes,
407	Vim can do the impossible).  To really make Vim forget about a buffer,
408	use ":bwipe".  Also see the 'buflisted' option.
409
