Module Ecaml.Filename

The name of a file. Functions in this module work directly on names, but do not read from or write to the filesystem.

val (<>) : t -> t -> bool

val compare : t -> t -> int

compare t1 t2 returns 0 if t1 is equal to t2, a negative integer if t1 is less than t2, and a positive integer if t1 is greater than t2.

val min : t -> t -> t
val max : t -> t -> t
val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~compare:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool

between t ~low ~high means low <= t <= high

val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).

val temporary_directory_for_current_buffer : unit -> t

(describe-function 'temporary-file-directory). Beware, if the current buffer is a tramp buffer on a remote host, then the temporary file directory will be on the remote host. This function is only available starting in emacs 26. In earlier versions, this reads the variable (describe-variable 'temporary-file-directory).

val temporary_directory_var : t Var.t

(describe-variable 'temporary-file-directory). The directory to use for writing temporary files.
