"
" 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
"
" Installation
" ------------
" 1. Copy the mru.vim file to one of the following directories:
" $HOME/.vim/plugin - Unix like systems
" $HOME/vimfiles/plugin - MS-Windows
" $VIM:vimfiles:plugin - Macintosh
" $VIM/vimfiles/plugin - All
" 2. Restart Vim.
" 3. 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 this plugin, remove this file (mru.vim) from the
" $HOME/.vim/plugin or $HOME/vimfiles/plugin or the $VIM/vimfile/plugin
" directory.
"
" Usage
" -----
" To list and edit files from the MRU list, you can use the ":MRU" command.
" The ":MRU" command displays the MRU file list in a temporary Vim window. If
" the MRU window is already opened, then the MRU list 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.
"
" 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 $USERPROFILE/_vim_mru_files
" for MS-Windows systems. You can change this variable to point to a file by
" adding the following line to the .vimrc file:
"
" let MRU_File = 'd:\myhome\_vim_mru_files'
"
" By default, the plugin will remember the names of the last 100 used files.
" As you edit more files, old file names will be removed from the MRU list.
" You can set the 'MRU_Max_Entries' variable to remember more file names. For
" example, to remember 1000 most recently used file names, you can use
"
" let MRU_Max_Entries = 1000
"
" By default, all the edited file names will be added to the MRU list. If you
" want to exclude file names matching a list of patterns, you can set the
" MRU_Exclude_Files variable to a list of Vim regular expressions. By default,
" this variable is set to an empty string. For example, to not include files
" in the temporary (/tmp, /var/tmp and d:\temp) directories, you can set the
" MRU_Exclude_Files variable to
"
" let MRU_Exclude_Files = '^/tmp/.*\|^/var/tmp/.*' " For Unix
" let MRU_Exclude_Files = '^c:\\temp\\.*' " For MS-Windows
"
" The specified pattern should be a Vim regular expression pattern.
"
" If you want to add only file names matching a set of patterns to the MRU
" list, then you can set the MRU_Include_Files variable. This variable should
" be set to a Vim regular expression pattern. For example, to add only .c and
" .h files to the MRU list, you can set this variable as below:
"
" let MRU_Include_Files = '\.c$\|\.h$'
"
" By default, MRU_Include_Files is set to an empty string and all the edited
" filenames are added to the MRU list.
"
" 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': '[^/\\]\+$'}
