objdiff-cli diff: Wishlist

[ribbanya]

Some things I think are missing from the diff workflow. Mostly here for discussion and so I don't forget to implement them. Can be broken up into separate issues as necessary (feel free to edit this post).

asm-differ flags

• --make (requires some restructuring of config structs like BuildConfig)
• --watch
• --width
• --threeway=prev
• --threeway=base
• --diff_mode=single
• --compress-matching
• --no-pager
• --format {color,plain,json} (not sure about HTML)

Pager features

• Center the view on the first change at startup
• Navigate between changes with ] and [
• Vim-like search (/ or ? to enter a string, Enter to confirm, n and b to navigate results)
• Something to go to the top or bottom of the entire diff. In Vim this is G and gg but I'm not sure if we want multi-character keystrokes.

UI

• Help page with scroll and search features, maybe h to activate?
• Show number of changes in a status bar somewhere ("1 of 5"). When the view changes, update to the first change in the view (from top to bottom).
• Show delta in percentage since the last change (red "▼x.xx%" or green "▲x.xx%")
• Show difference in bytes (raw bytes or as KB, not sure). asm-differ shows score from max_score down to 0 but I don't find that very useful personally.
• Toggle relaxed relocations with a hotkey
