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 works with both Vim and Neovim and will work on all the platforms
|
||
|
|
where Vim/Neovim are supported. This plugin will work in both console and GUI
|
||
|
|
Vim. This version of the MRU plugin needs Vim 7.0 and above.
|
||
|
|
|
||
|
|
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:
|
||
|
|
|
||
|
|
https://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 https://github.com/yegappan/mru/releases
|
||
|
|
2. Unzip the mru.zip file into the $HOME/.vim directory for Linux/MacOS/Unix
|
||
|
|
systems or the $HOMEPATH/vimfiles directory for MS-Windows. 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. Start Vim and run the ":helptags ALL" command to process the help file.
|
||
|
|
Without this step, you cannot jump to the MRU 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/mru.txt
|
||
|
|
files from either the $HOME/.vim or $HOME/vimfiles directory.
|
||
|
|
|
||
|
|
You can also install the latest version of the plugin directly from github
|
||
|
|
using the following steps (in Vim 8.0 and above): >
|
||
|
|
|
||
|
|
$ mkdir -p $HOME/.vim/pack/downloads/start/mru
|
||
|
|
$ cd $HOME/.vim/pack/downloads/start/mru
|
||
|
|
$ git clone https://github.com/yegappan/mru.git
|
||
|
|
<
|
||
|
|
For Neovim: >
|
||
|
|
|
||
|
|
$ mkdir -p $HOME/.config/nvim/pack/downloads/start/mru
|
||
|
|
$ cd $HOME/.config/nvim/pack/downloads/start/mru
|
||
|
|
$ git clone https://github.com/yegappan/mru.git
|
||
|
|
<
|
||
|

|
|
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.
|
||
|
|
|
||
|
|
*:MRUToggle*
|
||
|
|
Alternatively, you can use the ":MRUToggle" command to toggle (open or close)
|
||
|
|
the MRU window. If the window is already opened, then running the ":MRUToggle"
|
||
|
|
command will close the window.
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
In the MRU window, the following keys can be used:
|
||
|
|
|
||
|
|
<Enter> - open the file under cursor
|
||
|
|
o - open the file under cursor in a horizontally split window
|
||
|
|
<S-Enter> - idem
|
||
|
|
O - open the file under cursor in a vertically split window
|
||
|
|
v - open the file under cursor in read-only mode
|
||
|
|
t - open the file under cursor in a tab page
|
||
|
|
p - open the file under cursor in the preview window
|
||
|
|
u - update (refresh) the MRU list
|
||
|
|
d - delete the file name under cursor from the MRU list
|
||
|
|
q - close the MRU window
|
||
|
|
<Esc> - idem
|
||
|
|
|
||
|
|
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/refresh the file list.
|
||
|
|
This is useful if you keep the MRU window open always.
|
||
|
|
|
||
|
|
You can press the 'd' key to remove the entry under the cursor in the MRU
|
||
|
|
window from the MRU list.
|
||
|
|
|
||
|
|
You can close the MRU window by pressing the 'q' key or the <Esc> key or
|
||
|
|
using one of the Vim window commands.
|
||
|
|
|
||
|
|
By default, the MRU window is opened as the bottom-most window. If you are
|
||
|
|
using Vim version 8.0 and above, then you can use command modifiers like
|
||
|
|
|:topleft| or |:botright| or |:vertical| with the :MRU command to control
|
||
|
|
where the window is opened. Example: >
|
||
|
|
|
||
|
|
:topleft MRU " horizontally split topmost window
|
||
|
|
:botright MRU " horizontally split bottommost window
|
||
|
|
:vertical topleft MRU " vertically split far-left window
|
||
|
|
:vertical botright MRU " vertically split far-right window
|
||
|
|
<
|
||
|
|
By default, the height of the MRU window is 8 or the value specified by the
|
||
|
|
g:MRU_Window_Height variable. You can pass a count to the :MRU command to use
|
||
|
|
a different height. Example: >
|
||
|
|
|
||
|
|
:15MRU
|
||
|
|
:vertical topleft 20MRU
|
||
|
|
<
|
||
|
|
To display only files matching a pattern from the MRU list in the MRU window,
|
||
|
|
you can specify a pattern to the |:MRU| command. Example: >
|
||
|
|
|
||
|
|
:MRU mystr
|
||
|
|
<
|
||
|
|
The above command displays only the file names containing the string "mystr"
|
||
|
|
in them. 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 the search pattern supplied to the |:MRU| command matches only one file,
|
||
|
|
then the file will be opened in the current window if it contains an
|
||
|
|
unmodified buffer. Otherwise it will be opened in a new window. You can use
|
||
|
|
command-line completion to select a file and directly open the file without
|
||
|
|
opening the MRU window. If you are using Vim version 8.0 and above, you can
|
||
|
|
use the command modifiers (|:leftabove|, |:rightbelow|, |:vertical|, |:tab|,
|
||
|
|
etc.) to open the file in a horizontally or vertically split window or a tab
|
||
|
|
page. Example: >
|
||
|
|
|
||
|
|
:topleft MRU myfile.py " horizontally split topmost window
|
||
|
|
:botright MRU myfile.py " horizontally split bottommost window
|
||
|
|
:vertical MRU myfile.py " vertically split window
|
||
|
|
:vertical topleft MRU myfile.py " vertically split far-left window
|
||
|
|
:vertical botright MRU myfile.py " vertically split far-right window
|
||
|
|
:tab MRU myfile.py " new tab page
|
||
|
|
<
|
||
|
|
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.
|
||
|
|
|
||
|
|
*:MruRefresh*
|
||
|
|
After using the MRU plugin for a period of time, the MRU list may contain
|
||
|
|
files which are no longer present in the system. The |:MruRefresh| command can
|
||
|
|
be used to remove non-existing files from the MRU list.
|
||
|
|
|
||
|
|
*MruGetFiles()*
|
||
|
|
The MruGetFiles() function can be used to get the current list of file names
|
||
|
|
in the MRU list as a |List|. This can be used with Ex commands that accept one
|
||
|
|
or more file names as argument. Some example uses for this function are below:
|
||
|
|
>
|
||
|
|
" search for 'my_text' in all the files in the MRU list
|
||
|
|
:vimgrep my_text `=MruGetFiles()`
|
||
|
|
" search for 'my_text' in the files ending in .java in the MRU list
|
||
|
|
:vimgrep my_text `=MruGetFiles('.java')`
|
||
|
|
" add all the .py files in the MRU list to the argument list
|
||
|
|
:n `=MruGetFiles('.py')`
|
||
|
|
" Add the files in MRU list to a quickfix list
|
||
|
|
:call setqflist([], ' ', {'efm' : '%f', 'lines' : MruGetFiles()})
|
||
|
|
<
|
||
|
|

|
||
|
|
4. Configuration *mru-configuration*
|
||
|
|
|
||
|
|
The MRU plugin supports many configurable features. These can be enabled or
|
||
|
|
disabled by setting one or more variables in your .vimrc file using the |:let|
|
||
|
|
command. For Neovim, set these variables in the $HOME/.config/nvim/init.vim
|
||
|
|
file. A summary of these variables is below:
|
||
|
|
|
||
|
|
|MRU_File| name of the file containing the MRU list
|
||
|
|
|MRU_Max_Entries| size of the MRU list
|
||
|
|
|MRU_Exclude_Files| pattern to exclude files from MRU list
|
||
|
|
|MRU_Include_Files| pattern to include files in the MRU list
|
||
|
|
|MRU_Window_Height| height of the MRU window
|
||
|
|
|MRU_Use_Current_Window| use current window to display MRU list
|
||
|
|
|MRU_Auto_Close| close the MRU window when a file is selected
|
||
|
|
|MRU_Window_Open_Always| open the MRU window even for a single file
|
||
|
|
|MRU_Open_File_Use_Tabs| open files in separate tab pages
|
||
|
|
|MRU_FuzzyMatch| use fuzzy match for filtering file names
|
||
|
|
|MRU_Add_Menu| add MRU files to the "Recent Files" menu
|
||
|
|
|MRU_Max_Menu_Entries| maximum number of entries in the MRU menu
|
||
|
|
|MRU_Max_Submenu_Entries| maximum number of entries in the MRU submenu
|
||
|
|
|MRU_Set_Alternate_File| set the alternate file on plugin startup
|
||
|
|
|MRU_Filename_Format| patterns to populate and parse file names in
|
||
|
|
the MRU window
|
||
|
|
|
||
|
|
These variables are described in more detail below.
|
||
|
|
|
||
|
|
*MRU_File*
|
||
|
|
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'
|
||
|
|
<
|
||
|
|
*MRU_Max_Entries*
|
||
|
|
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
|
||
|
|
<
|
||
|
|
*MRU_Exclude_Files*
|
||
|
|
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 = '^D:\\temp\\.*' " For MS-Windows
|
||
|
|
<
|
||
|
|
The specified pattern should be a Vim regular expression pattern. Note that
|
||
|
|
you can specify multiple patterns using '\|'.
|
||
|
|
|
||
|
|
*MRU_Include_Files*
|
||
|
|
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 '\|'.
|
||
|
|
|
||
|
|
*MRU_Window_Height*
|
||
|
|
The default height of the MRU window is 8. You can set the MRU_Window_Height
|
||
|
|
variable to change the window height. You can also set the height of the MRU
|
||
|
|
window by passing a count to the :MRU command.
|
||
|
|
>
|
||
|
|
let MRU_Window_Height = 15
|
||
|
|
<
|
||
|
|
*MRU_Use_Current_Window*
|
||
|
|
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.
|
||
|
|
|
||
|
|
*MRU_Auto_Close*
|
||
|
|
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
|
||
|
|
<
|
||
|
|
*MRU_Window_Open_Always*
|
||
|
|
When a search pattern is supplied to the :MRU command, the MRU window is
|
||
|
|
opened if multiple files matching the pattern are found in the MRU list. If
|
||
|
|
only one matching file is found, instead of opening the MRU window the file is
|
||
|
|
directly opened. To force open the MRU window always, you can set the
|
||
|
|
MRU_Window_Open_Always variable to 1. By default this variable is set to 0.
|
||
|
|
>
|
||
|
|
let MRU_Window_Open_Always = 1
|
||
|
|
<
|
||
|
|
*MRU_Open_File_Use_Tabs*
|
||
|
|
When opening a file from the MRU list, the file is opened in the current
|
||
|
|
tab. If the selected file has to be opened in a tab always, then set the
|
||
|
|
following variable to 1. If the file is already opened in a tab, then the
|
||
|
|
cursor will be moved to that tab.
|
||
|
|
>
|
||
|
|
let MRU_Open_File_Use_Tabs = 1
|
||
|
|
<
|
||
|
|
*MRU_FuzzyMatch*
|
||
|
|
The :MRU command accepts a string that is used to filter the file names
|
||
|
|
displayed in the MRU window. The MRU command also supports command-line
|
||
|
|
completion using the supplied string. If Vim supports fuzzy matching
|
||
|
|
(supported from Vim 8.2.1665), then the :MRU command will fuzzy match the
|
||
|
|
supplied string against the file names. Otherwise it will use regular
|
||
|
|
expression matching. To always use regular expression matching, you can set
|
||
|
|
the MRU_FuzzyMatch variable to 0:
|
||
|
|
>
|
||
|
|
let MRU_FuzzyMatch = 0
|
||
|
|
<
|
||
|
|
*MRU_Add_Menu*
|
||
|
|
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
|
||
|
|
<
|
||
|
|
*MRU_Max_Menu_Entries*
|
||
|
|
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
|
||
|
|
<
|
||
|
|
*MRU_Max_Submenu_Entries*
|
||
|
|
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
|
||
|
|
<
|
||
|
|
*MRU_Set_Alternate_File*
|
||
|
|
When the MRU plugin starts up, if the MRU_Set_Alternate_File variable is set
|
||
|
|
to 1, then it sets the alternate file (|alternate-file|) to the first file in
|
||
|
|
the MRU list. You can edit this file using the ":e #" command. By default this
|
||
|
|
variable is set to 0. You can enable this behavior, by setting the
|
||
|
|
MRU_Set_Alternate_File variable to 1:
|
||
|
|
>
|
||
|
|
let MRU_Set_Alternate_File = 1
|
||
|
|
<
|
||
|
|
*MRU_Filename_Format*
|
||
|
|
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.
|
||
|
|
|
||
|
|
The MRU_Filename_Format variable contains a |Dict| with the following keys:
|
||
|
|
formatter: a string value containing an expression that specifies how to
|
||
|
|
split/format the filename. In the expression v:val refers to the
|
||
|
|
complete path to a file in the MRU list.
|
||
|
|
parser : a string value containing an regular expression that specifies
|
||
|
|
how to read the filename back from a line in the MRU window.
|
||
|
|
syntax : a string value with a regular expression that matches the part to
|
||
|
|
be highlighted in the MRU window.
|
||
|
|
|
||
|
|
For example, to display the full path of the files 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.
|
||
|
|
|
||
