Therefore I copy them in a folder  ".src/LIB". If it exists, I know,
that I'm debugging a lib in the project.

Hmm. That was the thing I've tried first, but somehow Gambas IDE removed
the writable-flag from the sourcefiles I'v symlinked. So I had to fiddle
around with a broken library afterwards.

I did not try if Gambas IDE does that already.

That's normal programmer's life. Permanently there is something you did
not think about before.

:-)

For that I try to keep code as long as possible inside the project, so
it becomes stable by testing over time. And if it's done it can be
shared. But even then sometimes I have to rewrite portions of it and
sometimes also interfaces.

Fortunately I work with Git and can do a fast "git grep" over the whole
sources to find all occurences.


Alles Gute
