      Implement directory refresh · 6c2ab500
      Yorhel authored
      This complicated the scan code more than I had anticipated and has a
      few inherent bugs with respect to calculating shared hardlink sizes.
      
      Still, the merge approach avoids creating a full copy of the subtree, so
      that's another memory usage related win compared to the C version.
      On the other hand, it does leak memory if nodes can't be reused.
      
      Not quite as well tested as I should have, so I'm sure there's bugs.

      Add link path listing to information window · ff3e3bcc
      Yorhel authored
      Two differences compared to the C version:
      - You can now select individual paths in the listing, pressing enter
        will open the selected path in the browser window.
      - Creating this listing is much slower and requires, in the worst case,
        a full traversal through the in-memory tree. I've tested this without
        the same-dev and shared-parent optimizations (i.e. worst case) on an
        import with 30M files and performance was still quite acceptable - the
        listing completed in a second - so I didn't bother adding a loading
        indicator. On slower systems and even larger trees this may be a
        little annoying, though.
      
      (also, calling nonl() apparently breaks detection of the return key,
      neither \n nor KEY_ENTER are emitted for some reason)

      Add item info window · 618972b8
      Yorhel authored
      Doesn't display the item's path anymore (seems rather redundant) but
      adds a few more other fields.

      Add workaround for Zig bug on FreeBSD · d910ed8b
      Yorhel authored
      The good news is: apart from this little thing, everything seems to just
      work(tm) on FreeBSD. Think I had more trouble with C because of minor
      header file differences.

      Update for Zig 0.8 HashMap changes · 40f9dff5
      Yorhel authored
      I had used them as a HashSet with mutable keys already in order to avoid
      padding problems. This is not always necessary anymore now that Zig's
      new HashMap uses separate arrays for keys and values, but I still need
      the HashSet trick for the link_count nodes table, as the key itself
      would otherwise have padding.

      Improved error reporting + minor cleanup · 59ef5fd2

      Handle allocation failures · 23903088
      Yorhel authored
      In a similar way to the C version of ncdu: by wrapping malloc(). It's
      simpler to handle allocation failures at the source to allow for easy
      retries, pushing the retries up the stack will complicate code somewhat
      more. Likewise, this is a best-effort approach to handling OOM,
      allocation failures in ncurses aren't handled and display glitches may
      occur when we get an OOM inside a drawing function.
      
      This is a somewhat un-Zig-like way of handling errors and adds
      scary-looking 'catch unreachable's all over the code, but that's okay.

      Implement JSON file import · c077c5be
      Yorhel authored
      Performance is looking great, but the code is rather ugly and
      potentially buggy. Also doesn't handle hard links without an "nlink"
      field yet.
      
      Error handling of the import code is different from what I've been doing
      until now. That's intentional, I'll change error handling of other
      pieces to call ui.die() directly rather than propagating error enums.
      The approach is less testable but conceptually simpler, it's perfectly
      fine for a tiny application like ncdu.

      Implement all existing browsing display options + some fixes · 7b3ebf92
      Yorhel authored
      I plan to add more display options, but ran out of keys to bind.
      Probably going for a quick-select menu thingy so that we can keep the
      old key bindings for people accustomed to it.
      
      The graph width algorithm is slightly different, but I think this one's
      a minor improvement.

      Implement export to file · 231ab103

      The exported file format is fully compatible with ncdu 1.x, but has a
      few minor differences. I've backported these changes in

      More UI stuff + shave off 16 bytes from model.Dir · 27cb599e
      Yorhel authored
      I initially wanted to keep a directory's block count and size as a
      separate field so that exporting an in-memory tree to a JSON dump would
      be easier to do, but that doesn't seem like a common operation to
      optimize for. We'll probably need the algorithms to subtract sub-items
      from directory counts anyway, so such an export can still be
      implemented, albeit slower.

      Implement --exclude-kernfs and --exclude-pattern · a28a0788
      Yorhel authored
      Eaiser to implement now that we're linking against libc.
      
      But exclude pattern matching is extremely slow, so that should really be
      rewritten with a custom fnmatch implementation. It's exactly as slow as
      in ncdu 1.x as well, I'm surprised nobody's complained about it yet.
      And while I'm at it, supporting .gitignore-style patterns would be
      pretty neat, too.

      Link to ncurses + some rudimentary TUI frameworky stuff · 826c2fc0
      Yorhel authored
      I tried playing with zbox (pure Zig termbox-like lib) for a bit, but I
      don't think I want to have to deal with the terminal support issues that
      will inevitably come with it. I already stumbled upon one myself: it
      doesn't properly put the terminal in a sensible state after cleanup in
      tmux. As much as I dislike ncurses, it /is/ ubiquitous and tends to kind
      of work.

      WIP: Experimenting with a rewrite to Zig & a new data model · 0783d357
      Yorhel authored
      The new data model is supposed to solve a few problems with ncdu 1.x's
      'struct dir':
      - Reduce memory overhead,
      - Fix extremely slow counting of hard links in some scenarios
        (issue #121)
      - Add support for counting 'shared' data with other directories
        (issue #36)
      
      Quick memory usage comparison of my root directory with ~3.5 million
      files (normal / extended mode):
      
        ncdu 1.15.1:     379M / 451M
        new (unaligned): 145M / 178M
        new (aligned):   155M / 200M
      
      There's still a /lot/ of to-do's left before this is usable, however,
      and there's a bunch of issues I haven't really decided on yet, such as
      which TUI library to use.
      
      Backporting this data model to the C version of ncdu is also possible,
      but somewhat painful. Let's first see how far I get with Zig.
