A simple CLI tool for Finder sidebar modification.
NOTE: I clobbered this together with very little experience in C/CoreFoundation, as a result the code may be horrible.
*NOTE: As of 10.11 El Capitan you can also use sfltool to achieve similar things. Example:
$ sfltool add-item com.apple.LSSharedFileList.FavoriteItems file:///Path/To/Sidebar/Folder
List sidebar favorites items:
mysides list
Append a new item to the end of a list:
mysides add example file:///Users/Shared/example
Insert a new item at the start of the list:
mysides insert example file:///Users/Shared/example
Remove the item (by name):
mysides remove example
