My .vimrc includes the following lines:
if filereadable("my_source") :source my_source endif
That is, if the file 'my_source' exists in the folder where I open vim and it is readable, it is loaded automatically.
However, if I am editing a file in that folder and open another file (also in that same folder) via
:tabe, the source file 'my_source' is not loaded in the latter. Why? How can I have it automatically loaded when I open a new tab?
