Certainly. It is the !VMview application in
http://www.wra1th.plus.com/lua/zip/rlua525.zip
but you need RISC OS to use it. Its !RunImage file is
#! lua -------------------------------
do
local temp, src = arg[1], arg[2]
local lines = io.lines
local cpat = "^\t(%d+)\t%[(%d+)%]\t(.*)$"
local x,y = {},{} -- source, comment
for line in lines(src) do
x[1+#x] = line
end -- for
local lnum,op
local lfmt = "%6d\t%s"
for line in lines(temp) do
cline,lnum,op = line:match(cpat)
if lnum and op then
y[1+#y] = { tonumber(lnum),lfmt:format(tonumber(cline),op), }
end -- if
end -- for
local concat = table.concat
local fmt = "--[[\n%s\n--]]"
local gather = function(n)
local o = {}
for _,v in ipairs(y) do
if v[1] == n then o[1+#o] = v[2] end -- if
end -- for
return (#o > 0) and fmt:format(concat(o,"\n")) or ""
end -- \
local g
for i,l in ipairs(x) do
print(l)
g = gather(i)
if #g > 0 then print(g) end -- if
end -- for
end ----------------------------------------
where arg[2] is the pathname of the program source and arg[1] is
the pathname of the output of luac (lhf was absolutely right) on
the source file with flags -p -l. How things are piped to turn this
into something where you just drag the icon of the program source
onto !VMview's iconbar icon, is somewhat OS-dependent, so I will not
strain your patience with the details.
