Module Common


module Common: sig .. end
Basic types and definitions required throughout the system.

exception Bug of string
exception Finally of exn * exn
Raised when finalization after an exception failed, too. The first exception argument is the one raised by the initial function, the second exception the one raised by the finalizer.
exception Validation_error of string list
exception Unimplemented of string

type read_only 
Handy types for marking things read-only and read-write. One should not expose functions for converting between read_only/immutable/read_write because the private types expose the subtyping. Users would say "(db :> read_only Db.t)" to cast. The difference between read-only and immutable is that someone else can change a read-only object, while immutable never changes.

type never_returns 
never_returns should be used as the return type of functions that don't return and * might block forever, rather than 'a or _. This forces callers of such functions to * have a call to never_returns at the call site, which makes it clear to readers what's * going on. We do not intend to use this type for functions such as failwithf that * always raise an exception.
val never_returns : never_returns -> 'a

Error handling

val protectx : f:('a -> 'b) -> 'a -> finally:('a -> unit) -> 'b
See exn.mli
val protect : f:(unit -> 'a) -> finally:(unit -> unit) -> 'a
val critical_section : Mutex.t -> f:(unit -> 'a) -> 'a

Input Output

val read_wrap : ?binary:'a -> f:'b -> 'c -> [ `Deprecated_use_In_channel_with_file ]
val write_wrap : ?binary:'a -> f:'b -> 'c -> [ `Deprecated_use_Out_channel_with_file ]
val write_lines : string -> string list -> unit
write_lines fname lines writes each string in lines (plus a newline) to file fname.
val input_lines : ?fix_win_eol:bool -> Pervasives.in_channel -> string list
Completely reads an input channel and returns the results as a list of strings. Each line in one string.
val read_lines : string -> string list
read_lines filename Opens filename, reads all lines, and closes the file.
val fst3 : 'a * 'b * 'c -> 'a
triple handling

val snd3 : 'a * 'b * 'c -> 'b
val trd3 : 'a * 'b * 'c -> 'c

Option handling

val uw : 'a option -> 'a

Functions from function.ml

val ident : 'a -> 'a
val const : 'a -> 'b -> 'a
val (==>) : bool -> bool -> bool
val ascending : 'a -> 'a -> int
A comparator that returns results in ascending order.

A comparator that returns results in descending order.

val descending : 'a -> 'a -> int
val (^/) : string -> string -> string
same as Filename.concat
val failwithf : ('a, unit, string, unit -> 'b) Pervasives.format4 -> 'a
val invalid_argf : ('a, unit, string, unit -> 'b) Pervasives.format4 -> 'a
val exitf : ('a, unit, string, unit -> 'b) Pervasives.format4 -> 'a

type 'a return = private {
   return : 'b. 'a -> 'b;
}
val with_return : ('a return -> 'a) -> 'a
val equal : 'a -> 'a -> bool
toplevel binding for polymorphic equality (=). Named for easy use in labelled arguments (one can do f x y ~equal).
val phys_equal : 'a -> 'a -> bool

val close_in : Pervasives.in_channel -> unit
we have our own version of these two, the INRIA version doesn't release the runtime lock.
