The @showln macro was not merged because Tim closed it because nobody
commented positively for a week. We try to limit the number of exports in
Julia Base, and we try to not have too many related concepts to do almost
the same thing. I don't have a strong opinion on this, but Stefan's
suggestion to incorporate the file an line info in the output of @show
seems reasonable to me.
The good news is that you can use the macro if you put
function show_backtrace1(bt)
for t in bt
lkup = ccall(:jl_lookup_code_address, Any, (Ptr{Void}, Int32), t, 0)
if lkup != ()
fname, file, line = lkup
print("in ", fname, " at ", file, ", line ", line)
break
end
end
end
macro showln(exs...)
:(bt = backtrace(); @show $(esc(exs...)); print(" (");
show_backtrace1(bt); println(")"))
end
At the top of your source file.
