The behavior is actually intended like that. At least, this was the original idea for dyff
, because for the project that sparked this tool, the order of entries in the list was of great importance. The problem is when you have what is called "simple lists" where it is difficult to decide whether the list entry was modified or whether it was actually just moved in the list. So comparing index by index (compare entry one with entry one in the other list, ...) was not an option. The only exeception to that rule was for simple lists with exactly one entry each. In this edge case, it was easy just to say compare the only entry in the list with the only other entry in the other list.
Long story short, I can understand actually both behavior preferences. There are three kind of styles:
- Only compare list entries if it can be made sure that they can really be compared, e.g. only one entry in simple lists and entries with the same
name
(orid
, orkey
) in named-entry lists. - Progressive style, where in simple lists the list index is assumed to be relevant and lists are compared by index.
- Content specific style, where the tool would try to guess whether there is a similar entry in the other list at a different index and would compare them. This was always my idea for an improvement, however, this could be very error prone for more complex scenarios.
What I could do is the following: Introduce a command line flag to configure the compare style for lists that are not that easy to compare, mostly simple lists to be honest. The options would be safe
(current style), index
(second bullet point), or best guess
for the content specific comparison.

Indeed this is not easy, I see it now. I'd hope dyff would find simplest possible change (set of operations) that transforms on input file to another. Turns out this is complicated computer science task. For instance here is paper that proposes tree comparison algorithm and tests it on XML files.
Apparently implementation of my wish is harder than I anticipated.
