The name of a node or "(no name)" was written out in twenty places and
four local functions, a lower-case copy of a text in four files, the
test for a number, the file name of a template made comparable and the
heading of a direction in three and two, the green main button of a
panel in five and the key=value parameters of a self-test command in
five. Each of them is one helper now: name_of, tall_button_height and
main_button with the panel helpers, numeric with format, normalized
with the include helpers, heading_of with the plan geometry and
selftest_values with the tools; lower gives way to ToLower.
The include bank read every .inc of the scenery directory on the first use, on the main thread: opening the
switch panel or selecting a switch stopped the editor until all of them were read, which on a large scenery
directory under Windows takes long. The bank now starts looking as the editor starts, in the background,
and the main thread only reads the descriptions once the files are read.
- the switch drives, turntables and signals are read again from the bank when it changes; the panels show
"Looking for the templates..." meanwhile, only the edits which need the templates wait for them
- the sweep tool takes the templates from the bank instead of looking through the scenery directory again
- a folder linked into one of its own subfolders no longer leads the walk in circles
- the log tells how many templates were found and how long it took
