weird behavior with .f90 and .F90 files

[Srinath]

I opened a file (foo.f90) with macvim that had the .f90 suffix. Then,
I realized I wanted it preprocessed. [No jokes about fortran ...
space shuttle quality stuff ... man]. So in terminal, I moved the file
over to be foo.F90. Of course, MacVim notifies me that the foo.f90
files does not exist any more. So I ":q" that tab, and command-T for
a new tab.
Then I type ":e foo.F90" in the new tab, and the buffer appears blank,
with the file name listed as "foo.f90". Back to the lower cased
suffix. If I starte a new macvim session: $mvim foo.F90, it opens up
fine. Any insight? Some buffer voodoo?

Btw..thanks for all the help.

Bumping since I never got a response.

Do this:

mvim foo.F

type: foo.F in file (save and close).

mvim foo.f

type: foo.f in file (save and close)

then run mvim -d foo.F foo.f

These are 2 different files, but only the first loads.

I think you are running up against the case-insensitivity of Mac OS X Extended FS.  By default i believe most Macs are formatted as Mac OS X Extended (Journaled).  There is an option to create a Mac OS X Entended (Case-sensitive, Journaled) partition.  

This is not related to vim but the underlying FS.  

in /tmp try this:

touch me ME

If you do a ls, you'll only see "me" and not "ME"  and visa versa depending on which filename you put first after the touch command.

This blew my mind too as I thought the Mac OS was UNIX at heart.  If I'm off base please let me know and tell me how I can fix my FS.

Provided you're not actually on a HFSX Volume (which IIRC is still not the default) foo.F and foo.f are *one and the same*.
The default HFS+ is case-preserving which allows you to use upper- and lowercase letters in filenames but also will compare
them case-insensitive (thus foo.F == foo.f).

I have a case sensitive system.

Running vim in Terminal does the correct thing.

So, the file system case sensitivity is not the issue.

Any other ideas?

You may have to build a custom binary. Take a look at the discussion
titled "case insensitivity on hfsx" in the archives:
