Hi,
in luatex-plain, the example below
\font\grk=file:LinLibertine_R.otf:+mark;+mkmk;mode=node at 14.4pt
{\grk
μῆνιν ἄειδε θεὰ Πηληϊάδεω Ἀχιλῆος\hfill\break
οὐλομένην, ἣ μυρί' Ἀχαιοῖς ἄλγε' ἔθηκε}
\bye
triggers a call to onetimemessage() which is nil at the time when
the upvalue is created. Can we have calls to
fonts.loggers.onetimemessage() instead, so we can override that
one with our own logger?
hm, don't assume that all that logging will be exposed forever in a
generic way; a lot is for specific tracing only and i more or less
assume that for problematic issues one will use context as benchmark
anyway (in fact, I've even been thinking of a stripped down generic
variant i.e. no unneccessary more context and dev related overhead
(leaner and meaner) which is possible once we're stable.
Sounds good. As most of the tracing code follows a clear pattern
it might even be possible to recognize and drop it during the
merge.
So it's more convenient if I just uncommented the trace-bugs
elseif trace_bugs then
which means that the message will not be called outside context at all.
Fine with me.
On a related note, we would like to reduce verbosity. In
luatex-basics-gen.lua, could we have:
logs = logs or {
new=dummyreporter,
reporter=dummyreporter,
messenger=dummyreporter,
report=dummyfunction,
}
So we can provide our own “logs” table?
That needs thinking, as i cannot guarantee that logging will stay
the same for those modules; a wrapper might be more stable, so for
the moment I'll define this:
local dummyreporter = function(c)
return function(...)
(texio.reporter or texio.write_nl)(c .. : ..
string.formatters(...))
end
end
so, you can define texio.reporter which is not defined by default.
Fine with me.
(The namespaces are somewhat protected so i cannot oversee now what
messing with logs will bring in terms of side effects.)
Absolutely.
Thanks a lot
Philipp
