introduce bookmarks

[abertschi]

This issue discusses the introduction of bookmarks to VitaShell. Here are some design ideas:

• symlinks

  • FAT is a Microsoft Filesystem format and does not support symlinks https://msdn.microsoft.com/en-us/library/windows/desktop/ee681827%28v=vs.85%29.aspx

  • PS Vita recognises FAT partitions https://vitadevwiki.com/vita/File_Management

Given these limitations, bookmarks cannot be implemented with native symlinks.

• introduce VitaShell specific symlinks

  • 0xF11E0000
  • introduce magic number, 4 bytes, followed by a softlink string pointing to a target file
  • A symlink can point to a folder or file (and also to other symlink)

• When opening a file

  • Check for magic number
  • Check for valid path
  • Resolve link or open file when above invalid

• UI changes

  • New Menu entry:
    • Bookmarks
    • Show: changes CWD to bookmark folder
    • Add

Bookmarks are just files. Can be deleted/ renamed manually. Initially they have the same name as their target file/folder

Similar issue: #407. Once we have found a common ground regarding design, I'll be implementing it here https://github.com/abertschi/VitaShell/tree/feature/bookmarks

Status update: I think the menu entries are better placed this way:

• New
  • Add Bookmark
• More
  • Bookmarks
  • Recent files

Should I use the L or R Key for a shortcut jump to the bookmark directory?
