DESCRIPTION Unless you use a revision control system, you have to write backups yourself. The writebackup.vim plugin makes that a simple :WriteBackup command from within Vim, but you still have to remember to trigger the backup. The writebackupVersionControl.vim extension can make up for a missed backup when you have already made changes to the buffer, but have not persisted them yet, via :WriteBackupOfSavedOriginal. Still, wouldn't it be nice if Vim detected that you have made backups of a file in the past, and automatically creates a new backup - without any action on your side? This plugin builds on the writebackup.vim and writebackupVersionControl.vim plugins, and automatically writes a backup on a day's first write of a file that was backed up in the past, but not yet today. This gives you one no-hassle, worry-free backup every day. For many writebackup.vim use cases (like editing config files distributed all over /etc/), this initial "good state from the past" backup is the most important one. (And of course you can still manually trigger additional checkpoint backups via :WriteBackup as in the past.) USAGE Once any backup exists (you can check via :WriteBackupListVersions), a new backup will be written on each day when you first persist the buffer via :write, provided that the file has not been modified yet today. (Otherwise, you would not be able to undo the automatic backup via :WriteBackupDeleteLastBackup; the automatic backup would keep reappearing after each :write.) Watch out for file synchronization tools and version control systems that may silently update the file modification date to today and therefore prevent automatic backups! For this and other reasons, it is still a good practice to trigger backups via :WriteBackup yourself, and just use the writebackupAutomator plugin as a safety net, for those instances where you forget to backup.

install details

INSTALLATION The code is hosted in a Git repo at     https://github.com/inkarkat/vim-writebackupAutomator You can use your favorite plugin manager, or "git clone" into a directory used for Vim packages. Releases are on the "stable" branch, the latest unstable development snapshot on "master". This script is also packaged as a vimball. If you have the "gunzip" decompressor in your PATH, simply edit the *.vmb.gz package in Vim; otherwise, decompress the archive first, e.g. using WinZip. Inside Vim, install by sourcing the vimball or via the :UseVimball command.     vim writebackupAutomator*.vmb.gz     :so % To uninstall, use the :RmVimball command. DEPENDENCIES - Requires Vim 7.0 or higher. - Requires the writebackup.vim plugin (vimscript #1828), version 3.00 or   higher. - Requires the writebackupVersionControl.vim plugin (vimscript #1829),   version 3.21 or higher. - Requires the ingo-library.vim plugin (vimscript #4433), version 1.007 or   higher. INTEGRATION You can influence the behavior of the writebackupAutomator plugin via the buffer-local variable b:WriteBackup. When this is 0, no automatic backup will be done even when previous backups exist. Contrariwise, when set to 1, the buffer will be automatically backed up even when no backups exist so far. You can use this variable in autocmds, filetype plugins or a local vimrc to change the backup behavior for certain file types or files in a particular location.

writebackupAutomator.vba.gz	1.01	2012-02-27	7.0	Ingo Karkat	Rename b:writebackup to b:WriteBackup to be consistent with the other configuration variables of the WriteBackup family, and to avoid connotation with the built-in 'writebackup' setting.*** PLEASE UPDATE YOUR CONFIGURATION ***
