jfw: asciilifeform: was http://therealbitcoin.org/ml/btc-dev/2015-August/000146.html not the original vdiff.sh release?
asciilifeform: jfw: correct (there was at least 1 earlier draft posted in the chan prior) -- but specifically it has the orig. timestampy version of 'vdiff.sh'
asciilifeform: may trinque forgive me for the spam, but will paste for comparison :
asciilifeform: diff -uNr $1 $2 | awk 'm = /^(---|\+\+\+)/{s="sha512sum \"" $2 "\" 2>/dev/null " | getline x; if (s) { split(x, a, " "); o = a[1]; } else {o = "false";} print $0 " " o} !m { print $0 }'
asciilifeform: vs. the later, revised item :
asciilifeform: diff -uNr $1 $2 | awk 'm = /^(---|\+\+\+)/{s="sha512sum \"" $2 "\" 2>/dev/null " | getline x; if (s) { split(x, a, " "); o = a[1]; } else {o = "false";} print $1 " " $2 " " o} !m { print $0 }
asciilifeform: the former gave timestamp, e.g. +++ b/foo 2020-06-16 17:37:55.000000000 -0400 e79b8ad22b34a54be999f4eadde2ee895c208d4b3d83f1954b61255d2556a8b73773c0dc0210aa044ffcca6834839460959cbc9f73d3079262fc8bc935d46262

asciilifeform: note that both of these -- obsolete; afaik nobody's used'em since phf's keccakized vdiff posted.
jfw: oh I see now, ty.
asciilifeform: np. the above is all there was to it.
