Sometimes I accidentally tell vim to edit a directory instead of a file in it
vim directory-name # what I typed vim directory-name/blah.txt # what I meant to type
Instead of immediately giving an error message, vim will open the directory in a "file editor" mode that I personally don't like:
How can I make vim refuse to open directories instead?
One possible avenue could be by changing some settings in my .vimrc but I don't know what they would be.
Another possibility would be to create a wrapper shell alias around vim that checks with something along the lines of
test -d "$1" to see if I'm trying to open a file. However, I don't know to make this alias robust so that it can tell apart which command-line arguments are flags and which are file names.
