How do I enable the output of for example:
report_typescripts("unknown library %a or %a",name_one,name_two)
defined by
local report_typescripts = logs.reporter("fonts","typescripts")

Hi Hans,

`logs.reporter("fonts","typescripts")` returns a function for writing
to the log. Calling that function produces this sort of output:
fonts > typescripts > bla bla bla
Sometimes calls to a reporter are wrapped in a 'only if tracker x is
active'. This is not the case with this reporter, though. If this
reporter is not printing anything, it's because the error condition is
not arising, not because you didn't activate some tracker.
For completeness: the wiki has more on trackers, including a list of them.
http://wiki.contextgarden.net/Trackers
And this is what a reporter wrapped in a tracker looks like:
-- defining the tracker
local trace_casing = false
trackers.register("typesetters.casing", function(v) trace_casing = v end)
-- checking whether the tracker is active
if trace_casing then
report_casing("case trigger %a, instance %a, result
%a",attr%100,div(attr,100),ok)
end
Hope this helps,
Sietse

Klopt. En verschillende modules kunnen dezelfde tracker gebruiken (een
ietwat complex onderliggend mechanisms zorgt er voor dat alles wordt
gesynchroniseerd).
Men kan ook in texsmfcnf.lua dingen instellen (trackers, directives,
experiments). Men kan die dingen op verschillende momenten instellen:
- commandline
- environment
- cnf file
- tex/lua file
in volgorde van prioriteit.
