You would call it from an AppleScript. That script would look something like
this:
tell application "BBEdit"
set top to true
repeat
set f to find "[\\da-f]+" searching in text 1 of text document
1 options {search mode:grep, starting at top:top, wrap around:false,
backwards:false, case sensitive:false, match words:false, extend
selection:false} with selecting match
if (found of f) then
set t to found text of f
else
exit repeat
end if
set selection of window 1 to my fromHex(t)
set top to false
end repeat
end tell
on fromHex(str)
...
end fromHex
But you will have to do some fine tuning of the grep pattern to make it find
hex strings and only hex strings. I just used [\da-f]+ for testing. You might
also want to use case sensitive:true, match words:true. I don't know what will
work best without seeing the files you're working with, but you can figure it
out.
