|
|
" 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.
|
|
"
|
|
" The recently used filenames are stored in a file specified by the Vim
|
|
" MRU_File variable.
|
|
"
|
|
" Installation
|
|
" ------------
|
|
" 1. Copy the mru.vim script to the $HOME/.vim/plugin or the
|
|
" $HOME/vimfiles/plugin or the $VIM/vimfiles directory. Refer to the
|
|
" ':help add-plugin', ':help add-global-plugin' and ':help runtimepath'
|
|
" topics for more details about Vim plugins.
|
|
" 2. Set the MRU_File Vim variable in the .vimrc file to the location of a
|
|
" file to store the most recently edited file names.
|
|
" 3. Restart Vim.
|
|
" 4. 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.
|
|
"
|
|
" Usage
|
|
" -----
|
|
" You can use the ":MRU" command to list all the most recently edited file
|
|
" names. The file names will be listed in a temporary Vim window. If the MRU
|
|
" window is already opened, then the MRU list displayed in the window will be
|
|
" 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 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.
|
|
"
|
|
" You can press the 'o' key to open the file name under the cursor in the
|
|
" MRU window in a new window.
|
|
"
|
|
" 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.
|
|
"
|
|
" You can close the MRU window by pressing the 'q' key or using one of the Vim
|
|
" window commands.
|
|
"
|
|
" You can use the ":MRUedit" command to edit files from the MRU list. This
|
|
" command supports completion of file names from the MRU list. You can specify
|
|
" the file either by the name or by the location in the MRU list.
|
|
"
|
|
" 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.
|
|
"
|
|
" 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 edit 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 systems and $VIM/_vim_mru_files for non-Unix
|
|
" 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 10 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 20 most recently used file names, you can use
|
|
"
|
|
" let MRU_Max_Entries = 20
|
|
"
|
|
" 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.
|
|
"
|
|
" 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
