Before it's non-embarrassingly releasable:
- - work out what to do about atimes on directories in the absence of
- the Linux syscall magic
- * one option is to read them during the scan and reinstate them
- after each recursion pop. Race-condition prone.
- * marking them in a distinctive colour in the reports is another
- option.
- * a third option is simply to ignore space taken up by
- directories in the first place; inaccurate but terribly simple.
- * incidentally, sometimes open(...,O_NOATIME) will fail, and
- then we have to fall back to ordinary open. Be prepared to do
- this, which probably means getting rid of the icky macro
- hackery in du.c and turning it into a more sensible run-time
- abstraction layer.
+ - arrange to be able to identify directories and leave them on one
+ side of the usual age display
- cross-Unix portability:
+ use autoconf
straight to terminfo: generate lines of attribute-interleaved
text and display them, so we only really need the sequences
"go here and display stuff", "scroll up", "scroll down".
- + I think the attribute-interleaved text might be possible to do
- cunningly, as well: we autodetect a basically VT-style
- terminal, and add 256-colour sequences on the end. So, for
- instance, we might set ANSI-yellow foreground, set ANSI-red
- background, _then_ set both foreground and background to the
- appropriate xterm 256-colour, and then display some
- appropriate character which would have given the right blend
- of the ANSI-16 fore and background colours. Then the same
- display code should gracefully degrade in the face of a
- terminal which doesn't support xterm-256.
- * current best plan is to simulate the xterm-256 shading from
- 0/5 to 5/5 by doing space, colon and hash in colour A on
- colour B background, then hash, colon and space in B on A
- background.
+ Infrastructure work before doing any of this would be to split
html.c into two: one part to prepare an abstract data
structure describing an HTML-like report (in particular, all
