There has been a request that when adding items to the quickfix list, no
buffer is created to hold the file name.
The reason is that when there are many different file names this causes
the buffer list to get very long, which then causes various operations
to become slow. Including finding the buffer for a file name.
Instead of using a buffer, where the file name is stored, and then using
the buffer number, the file name itself could be remembered.
Since there are so many quickfix commands, adding a flag to every one of
them would be creating quite a mess. We could add an option, but
that has the danger of forgetting to reset the option after the
operation. And it requires three more statements (save current value,
set the option, restore th option). So I was thinking of using a command
modifier:
:usefname caddexpr {expr}
How about that?
Storing the file name instead of a buffer number has a few
disadvantages:
- When inserting or deleting lines in the file the position of the
quickfix items is not adjusted.
- Using more memory to store a copy of the file name.
- Changing directory can make the file name invalid. We could store the
full path, but creating that also adds overhead. Hmm, perhaps we
could store the full path the moment the directory is changed.
