as a rule, one should not rely on "using namespace xyz",
since this makes organisation of minimal header includes near impossible.
You end up with mass includes in some "top level" headers, resulting
in painfully slow compilation turnaround times.
In exceptional cases, using namespace foo might be adequate though
reason is, only files with a @file comment will be processed
with further documentation commands. For this reason, our Doxygen
documentation is lacking a lot of entries.
HOWTO:
find src -type f \( -name '*.cpp' -or -name '*.hpp' \) -not -exec egrep -q '\*.+@file' {} \; -print -exec sed -i -r -e'\_\*/_,$ { 1,+0 a\
\
\
/** @file §§§\
** TODO §§§\
*/
}' {} \;
over time, a specific Lumiera code writing style has emerged.
The GUI, as it stood, used somewhat different conventions,
which now have been aligned to the common standard.
Basically we use GNU style, with some adjustments for OO-programming,
we prefer CamelCase, and write TypeNames uppercase, variableNames lowercase
it is a widely accepted rule to shape names with the usage site in mind.
Especially this means, that we use the singular form for all kinds
of collections and assortments.
Thus, the namespace should be called "widget" not "widgets",
because at usage site this becomes gui::widget::TimelineWidget
Likewise for "dialogs" and "pannels"
