val run_main : (unit -> unit) -> _
val write_wrap : ?mode:[ `Clobber | `Append | `Atomic | `Atomic_update ] -> f:(out_channel -> 'a) -> string -> 'a

write_wrap ~atomic ~f fname Runs f on an out_channel. If mode is `Atomic or `Atomic_update is set all the changes will be written to a temporary file which will then be moved over fname otherwise we are writing straight to fname.

Values for mode:

  • `Clobber: clear the file on opening (this is the default value)
  • `Append: append to the file
  • `Atomic: replace the file atomically when we are done writing it
  • `Atomic_update: replace the file atomically when we are done writing it iff its content has been modified.
