Add a value to existing value containers without replacing them. Depending on the type of the container, the arguments would change their meaning:

If it's a dictionary, e.g. insert "newkey" = 5:

bencedit> insert "" newkey 5

If it's a list, e.g. insert "foobar" at position 2:

bencedit> insert "" 2 foobar

There could be an alias to this command called append that adds to the new value to end of the list (if the container is a list). Also, maybe I should add a special case in bencode-rs for . to be an alias for the root value.

clear [selector]

With no arguments, the root value becomes an empty container if it is a container, and the default value for primitives.

Clear values

• dict: {}
• list: []
• int: 0
• str: ""
• bytes: b""

Primarily a concept for batch mode, this can also be useful for a transform command in interactive, so it should be on its own module.

For applying transforms in interactive mode as well. Depends on #4.

A command to remove an inner value from a container.

Pretty-printing is configurable for example, but we still lack the actual command to control that, among other things.

bencedit would keep track of the changes done to the structure and jump back and forth to them. An undo/redo function, basically.

Commands

• undo [n]: Go back n (or 1 if not specified) changes
• redo [n]: Go forward n (or 1 if not specified) changes
• changes: List all the changes in the file, prefixed by a number
• change n: Go to a specific change n, a number from the previous command.

As usual, if you make any changes while in an earlier history, all the late changes will be discarded.

And also save-as. Files will only be saved if there were changes made in the structure.

Should files be loaded all at once, or only when it's their turn to be processed?
