1. Overview					*mru-overview*

The Most Recently Used (MRU) plugin provides an easy access to a list of
recently opened/edited files in Vim. This plugin automatically stores the
file names as you open/edit them in Vim.

This plugin will work on all the platforms where Vim is supported. This
plugin will work in both console and GUI Vim. This version of the MRU
plugin needs Vim 7.0 and above. If you are using an earlier version of
Vim, then you should use an older version of the MRU plugin.

The recently used filenames are stored in a file specified by the Vim
MRU_File variable.

The Github repository for the MRU plugin is available at:

      http://github.com/yegappan/mru

==============================================================================
2. Installation					*mru-installation*

You can use any one of the Vim plugin managers (dein.vim, pathogen, vam,
vim-plug, volt, Vundle, etc.) to install and manage this plugin.

Alternatively, you can also manually download and install the plugin
using the following steps.

1. Download the mru.zip file from the vim.sourceforge.io site.
2. Unzip the files into the $HOME/.vim or the $HOME/vimfiles directory.  After
   this step, you should have the following files (the directory structure
   should be preserved):

	plugin/mru.vim - MRU plugin
	doc/mru.txt    - documentation (help) file

3. Change to the $HOME/.vim/doc or $HOME/vimfiles/doc or $VIM/vimfiles/doc
   directory, start Vim and run the ":helptags ." command to process the
   help file. Without this step, you cannot jump to the help topics.
4. Restart Vim.
5. You can use the |:MRU| command to list and edit the recently used files.
   In GUI Vim, you can use the 'File->Recent Files' menu to access the
   recently used files.

To uninstall the MRU plugin, either use the uninstall command provided by the
plugin manager or manually remove the plugin/mru.vim, and doc/greplace.txt
files from the $HOME/.vim or $HOME/vimfiles directory.

==============================================================================
3. Usage					*mru-usage* *:MRU*

To list and edit files from the Most Recently Used (MRU) list, you can use the
":MRU" command.  The |:MRU| command displays the list of recently used files
in a temporary Vim window.  If the MRU window is already opened, then the MRU
list currently displayed in the window is refreshed.

If you are using GUI Vim, then the names of the recently edited files are
added to the "File->Recent Files" menu. You can select the name of a file
from this sub-menu to edit the file.

You can use the normal Vim commands to move around in the MRU window. You
cannot make changes in the MRU window.

You can select a file name to edit by pressing the <Enter> key or by double
clicking the left mouse button on a file name.  The selected file will be
opened. If the file is already opened in a window, the cursor will be moved
to that window. Otherwise, the file is opened in the previous window. If the
previous window has a modified buffer or is the preview window or is used by
some other plugin, then the file is opened in a new window.

You can press the 'o' key to open the file name under the cursor in the
MRU window in a new window. You can also press <Shift-Enter> instead of 'o'
to open the file in a new window.

To open a file from the MRU window in read-only mode (view), press the 'v'
key.

To open a file from the MRU window in a new tab, press the 't' key.  If the
file is already opened in a window in the current or in another tab, then
the cursor is moved to that tab. Otherwise, a new tab is opened.

You can open multiple files from the MRU window by specifying a count before
pressing '<Enter>' or 'v' or 'o' or 't'. You can also visually (using
linewise visual mode) select multiple filenames and invoke the commands to
open the files. Each selected file will be opened in a separate window or
tab.

You can press the 'u' key in the MRU window to update the file list. This is
useful if you keep the MRU window open always.

You can close the MRU window by pressing the 'q' key or the <Esc> key or
using one of the Vim window commands.

To display only files matching a pattern from the MRU list in the MRU
window, you can specify a pattern to the |:MRU| command. For example, to
display only file names matching "vim" in them, you can use the following
command ":MRU vim".  When you specify a partial file name and only one
matching filename is found, then the |:MRU| command will edit that file.

The |:MRU| command supports command-line completion of file names from
the MRU list. You can enter a partial file name and then press <Tab>
or <Ctrl-D> to complete or list all the matching file names. Note that
after typing the |:MRU| command, you have to enter a space before completing
the file names with <Tab>.

When a file supplied to the |:MRU| command is not present in the MRU list,
but it is a readable file, then the file will be opened (even though it is
not present in the MRU list). This is useful if you want to open a file
present in the same directory as a file in the MRU list. You can use the
command-line completion of the |:MRU| command to complete the full path of a
file and then modify the path to open another file present in the same path.

Whenever the MRU list changes, the MRU file is updated with the latest MRU
list. When you have multiple instances of Vim running at the same time, the
latest MRU list will show up in all the instances of Vim.

The MRUFilename syntax group is used to highlight the file names in the MRU
window. By default, this syntax group is linked to the Identifier highlight
group. You can change the highlight group by adding the following line in
your .vimrc:
>
   highlight link MRUFileName LineNr
<
The MRU buffer uses the 'mru file type. You can use this file type to add
custom auto commands, syntax highlighting, etc.

==============================================================================
4. Configuration				*mru-configuration*

By changing the following variables you can configure the behavior of this
plugin. Set the following variables in your .vimrc file using the 'let'
command.

The list of recently edited file names is stored in the file specified by the
MRU_File variable.  The default setting for this variable is
$HOME/.vim_mru_files for Unix-like systems and $USERPROFILE/_vim_mru_files
for MS-Windows systems. You can change this variable to point to a file by
adding the following line to the .vimrc file:
>
      let MRU_File = 'd:\myhome\_vim_mru_files'
<
By default, the plugin will remember the names of the last 100 used files.
As you edit more files, old file names will be removed from the MRU list.
You can set the 'MRU_Max_Entries' variable to remember more file names. For
example, to remember 1000 most recently used file names, you can use
>
      let MRU_Max_Entries = 1000
<
By default, all the edited file names are added to the MRU list. If you want
to exclude file names matching a pattern, then you can set the
MRU_Exclude_Files variable to a Vim regular expression. If any part of a
file name matches the regular expression, then it is not added to the MRU
list. By default, this variable is set to an empty string. For example, to
not include files in the temporary (/tmp, /var/tmp and d:\temp) directories,
you can set the MRU_Exclude_Files variable to
>
      let MRU_Exclude_Files = '^/tmp/.*\|^/var/tmp/.*'  " For Unix
      let MRU_Exclude_Files = '^c:\\temp\\.*'           " For MS-Windows
<
The specified pattern should be a Vim regular expression pattern. Note that
you can specify multiple patterns using '\|'.

If you want to add only file names matching a pattern to the MRU list, then
you can set the MRU_Include_Files variable. This variable should be set to a
Vim regular expression pattern. If the regular expression matches any part
of a file name, then it is added to the MRU list.  For example, to add only
.c and .h files to the MRU list, you can set this variable as below:
>
      let MRU_Include_Files = '\.c$\|\.h$'
<
By default, MRU_Include_Files is set to an empty string and all the edited
filenames are added to the MRU list. Note that you can specify multiple
patterns using '\|'.

The default height of the MRU window is 8. You can set the MRU_Window_Height
variable to change the window height.
>
      let MRU_Window_Height = 15
<
By default, when the |:MRU| command is invoked, the MRU list will be displayed
in a new window. Instead, if you want the MRU plugin to reuse the current
window, then you can set the 'MRU_Use_Current_Window' variable to one.
>
      let MRU_Use_Current_Window = 1
<
The MRU plugin will reuse the current window. When a file name is selected,
the file is also opened in the current window.

When you select a file from the MRU window, the MRU window will be
automatically closed and the selected file will be opened in the previous
window. You can set the 'MRU_Auto_Close' variable to zero to keep the MRU
window open.
>
      let MRU_Auto_Close = 0
<
If you don't use the "File->Recent Files" menu and want to disable it,
then you can set the 'MRU_Add_Menu' variable to zero. By default, the
menu is enabled.
>
      let MRU_Add_Menu = 0
<
If too many file names are present in the MRU list, then updating the MRU
menu to list all the file names makes Vim slow. To avoid this, the
MRU_Max_Menu_Entries variable controls the number of file names to show in
the MRU menu. By default, this is set to 10. You can change this to show
more entries in the menu.
>
      let MRU_Max_Menu_Entries = 20
<
If many file names are present in the MRU list, then the MRU menu is split
into sub-menus. Each sub-menu contains MRU_Max_Submenu_Entries file names.
The default setting for this is 10. You can change this to increase the
number of file names displayed in a single sub-menu:
>
      let MRU_Max_Submenu_Entries = 15
<
In the MRU window, the filenames are displayed in two parts. The first part
contains the file name without the path and the second part contains the
full path to the file in parenthesis. This format is controlled by the
MRU_Filename_Format variable. If you prefer to change this to some other
format, then you can modify the MRU_Filename_Format variable. For example,
to display the full path without splitting it, you can set this variable
as shown below:
>
      let MRU_Filename_Format =
      \   {'formatter':'v:val', 'parser':'.*', 'syntax': '[^/\\]\+$'}
<
==============================================================================
5. FZF Integration				*mru-fzf*

You can use the MRU plugin with FZF (command-line fuzzy finder). You can
download and install FZF from https://github.com/junegunn/fzf.

To select a file from the MRU file list using FZF, run the following command:
>
	:FZFMru
<
This will invoke FZF to select a file from the MRU list.
