Patch 7.2.031

Problem:    Information in the viminfo file about previously edited files is

	    not available to the user.  There is no way to get a complete list

	    of files edited in previous Vim sessions.

Solution:   Add v:oldfiles and fill it with the list of old file names when

	    first reading the viminfo file.  Add the ":oldfiles" command,

	    ":browse oldfiles" and the "#<123" special file name.  Increase

	    the default value for 'viminfo' from '20 to '100.

     The |:marks| command is useful to find out where '0 to '9 will take you.

+ GETTING BACK TO SOME FILE

+ 

+ If you want to go back to a file that you edited recently, but not when

+ exiting Vim, there is a slightly more complicated way.  You can see a list of

+ files by typing the command: >

+ 

+ 	:oldfiles

+ <	1: ~/.viminfo ~

+ 	2: ~/text/resume.txt ~

+ 	3: /tmp/draft ~

+ 

+ Now you would like to edit the second file, which is in the list preceded by

+ "2:".  You type: >

+ 

+ 	:e #<2

+ 

+ Instead of ":e" you can use any command that has a file name argument, the

+ "#<2" item works in the same place as "%" (current file name) and "#"

+ (alternate file name).  So you can also split the window to edit the third

+ file: >

+ 

+ 	:split #<3

+ 

+ That #<123 thing is a bit complicated when you just want to edit a file.

+ Fortunately there is a simpler way: >

+ 

+ 	:browse oldfiles

+ <	1: ~/.viminfo ~

+ 	2: ~/text/resume.txt ~

+ 	3: /tmp/draft ~

+ 	-- More --

+ 

+ You get the same list of files as with |:oldfiles|.  If you want to edit

+ "resume.txt" first press "q" to stop the listing.  You will get a prompt:

+ 

+ 	Type number and <Enter> (empty cancels): ~

+ 

+ Type "2" and press <Enter> to edit the second file.

+ 

+ More info at |:oldfiles|, |v:oldfiles| and |c_#<|.
