Due to the missing concept of one "package unit", that stores settings
for all units in that directory, there is also a question where to
store such settings.
Currently one way would be to replicate them to each and every unit in
the directory => a real bad idea, because nothing gurantees that the
setting will be equal for the whole package....
If there was one "package unit", that could be used to store setting
for all units, a unit could have a UUID in addition to a namespace =>
Then the project could map a new alias to such a UUID.
Having written this, here is an alternative idea.
Scrapping the -Fu extension (though that could stay, as an additional way).
In absence of a "package" declaration file, each "package" (as in
"collection of units in a folder" ), could have a local fpc.cfg file
- This file would not be allowed all kind of settings (since not all
settings would make sense)
- this file could:
-- Specify a namespace for the package
-- Specify a UUID for the package
the project could also have such an fpc.cfg config (maybe things could
be defined in the main program file? but they may need to be known, if
compiling any of the units...)
The program's fpc.cfg file could:
-- override namespaces, by referring to the UUID
So namespace conflicts can be solved per project
