val int_of_octal : string -> int

Returns the integer represented by the argument written in base 8.

val int_of_hex : string -> int

Returns the integer represented by the argument written in base 16.

val split_left_on_char : ?from:int -> char -> string -> string

If the character occurs in the substring beginning from from, returns the prefix that precedes the first occurrence (excluded), else returns the whole substring beginning from from.

val split_right_on_char : ?from:int -> char -> string -> string

If the character occurs in the substring beginning from from, returns the suffix that succedes the first occurrence (excluded), else returns the whole substring beginning from from.

val trim_carriage_return : string -> string

val option_find : ( 'a -> 'b ) -> 'a -> 'b option

option_find f x returns Some (f x), or None if f x raises Not_found.

val write_and_close : out_channel -> ( 'a -> 'b ) -> 'a -> 'b

write_and_close channel f arg calls f arg, and returns the result of f. channel is always closed after f has been called, even if f raises an exception.

val with_temp_file : string -> ( string -> in_channel -> 'a ) -> 'a

with_temp_file s f creates a temporary file with s as contents and calls f filename in_channel where filename is the name of the temporary file and in_channel is an input channel opened to read the file. The file is deleted after the execution of f (even if f raised an exception.

val with_pipe : ( in_channel -> out_channel -> 'a ) -> 'a

with_pipe f creates a pipe and calls f with the two ends of the pipe.

val with_stdin_from : in_channel -> ( 'a -> 'b ) -> 'a -> 'b

with_stdin_from chan f arg calls f arg with the standard input redirected for reading from chan.

val with_channel_from_string : string -> ( in_channel -> 'a ) -> 'a

with_channel_from_string s f calls f in_channel where in_channel is an input channel returning the contents of s.

val with_stdin_from_string : string -> ( 'a -> 'b ) -> 'a -> 'b

with_stdin_from_string s f arg calls f arg with the standard input redirected for reading from the contents of s.
