more convenient file backup util for vim

if you like my work, check here for a list of my vim plugins, or buy me a coffee

how to use

1. use Vundle or any other plugin manager you like to install

   Plugin 'ZSaberLv0/ZFVimBackup'
   

2. edit your file, backups would be made automatically when you save files, or, make backups manually by :ZFBackupSave or :ZFBackupSaveDir

3. if anything wrong, use :ZFBackupList or :ZFBackupListDir to popup and choose backup to diff and restore

functions

• ZFBackup_backupDir() : get backup dir
• ZFBackupSave [filePath] or call ZFBackupSave([filePath]) : save backup for specified file
• ZFBackupSaveDir [filePath] or call ZFBackupSaveDir([filePath]) : save backup for specified dir, wildignore and ZFIgnoreGet() are applied
• ZFBackupRemove [filePath] or call ZFBackupRemove([filePath]) : remove backup for specified file
• ZFBackupRemoveDir [filePath] or call ZFBackupRemoveDir([filePath]) : remove backup for specified dir
• ZFBackupList [filePath] or call ZFBackupList([filePath]) : restore backup for specified file
• ZFBackupListDir [filePath] or call ZFBackupListDir([filePath]) : restore backup for specified dir
• ZFBackup_getBackupInfoList([filePath]) or ZFBackup_getAllBackupInfoList() : get a list of backup info for specified file:

  [
    {
      'backupFile' : 'backup file name under backupDir',
      'name' : 'original file's name',
      'path' : 'original file's parent's abs path, may be empty when local config file messed up',
      'pathMD5' : 'original file's parent's abs path's md5',
      'time' : 'backup saved time, string',
      'info' : 'a short info to show the backup',
    },
  ]

  • you need one of thse command to make backup available:
    • md5 or md5sum (for Linux like systems)
    • certutil (for Windows)
  • if none of them are available, you may supply your own, or use the builtin vim script version by let g:ZFBackup_hashFunc_fallback_enable = 1 (which may be slow)

• g:ZFBackup_backupFilter : Dictonary that contain filter functions to filter files to backup, key is any module name you like, value is filter function function(filePath), return 1 to prevent the file from being backup, return 0 means the file needs backup, return -1 means pass to next filter, if all filter return -1, then it means the file needs backup

    to specify custom ignore for ZFBackup only:

    if !exists('g:ZFIgnoreData')
        let g:ZFIgnoreData = {}
    endif
    let g:ZFIgnoreData['MyCustomIgnore'] = {
                \   'ZFBackup' : {
                \     'file' : {
