I see ":truncate". This seems liek it will do the trick.
Problem: I would like to read from the file first before
Is there a way to do this, or should I
1) open the handle with :ro
2) read what I want from it
3) close the handle
4) reopen the handle with :w and overwrite what I want?
You have to do it the long way. I don't think we expose a binding to
ftruncate() that would let you open it r/.w, red from it, truncate,
That said, there's actually a good reason for that: is it okay to
trash the file if something goes wrong? You might prefer to *rename*
the old file instead of overwriting, so you can recover if necessary.
That is what I did. Thank you for the confirmation!
I suppose I should say at this point that the purpose of the file
is to be a single line with the date the program was last run
in it. If the current date's month and the month in the file
differ, it triggers an event in my program.
