Simple logging
- author Edgar Friendly
val output : unit BatIO.output Pervasives.ref
This ref holds the output channel for simple logging. Defaults to stderr
- since 2.0; had getter and setter in 1.x
val prefix : string Pervasives.ref
This ref holds the text printed before each log message. Defaults to the empty string.
- since 2.0; had getter and setter in 1.x
val flags : flag list Pervasives.ref
This ref holds the output flags. These flags control how the log messages are output. The default is `Date; `Time
and log messages are printed as:
2011/0628 01:23:45: prefixmessage
- since 2.0; had getter and setter in 1.x
log s
logs the message s, returning unit.
- since 2.0; was [print] in 1.x
val logf : ?fp:string -> ('a, unit BatIO.output, unit) Pervasives.format -> 'a
As Printf.printf
, only the message is printed to the logging output and prefixed with status information per the current flags and the currently set prefix.
- since 2.0; was [printf] in 1.x
fatal s
logs the message s
and then calls exit 1
. This exits the program with return code 1.
val fatalf :
?fp:string ->
('a, unit BatIO.output, unit) Pervasives.format ->
'a
fatalf
allows a format string (as Printf.printf
)and the arguments to that format string to build the logging message. Exits the program with return code 1.
module type Config = sig ... end
Build a logger module with custom, fixed output, prefix and flags
Returns an object with methods fatal
, fatalf
, log
, and logf
that logs to the given output channel, with given prefix and flags. These methods work like the corresponding functions in the BatLog module.
- since 2.0
val make_logger :
'a BatIO.output ->
string ->
[< `Custom of unit -> string | `Date | `Filepos | `Time ] list ->
< fatal : ?fp:string -> string -> 'b
; fatalf :
?fp:string ->
('c, 'a BatIO.output, unit, unit, unit, 'd) Pervasives.format6 ->
'c

; logf : ?fp:string -> ('e, 'a BatIO.output, unit) Pervasives.format -> 'e >
The different verbosity levels supported in the Easy
logger
module Easy : sig ... end
A simple-to-use logger with verbosity levels that outputs by default to stderr (changeable at runtime) with the date and time at the beginning of each log message.
