renderThreadTimeMessage :: LogEnv -> ThreadTimeMessage -> Text Source #
Render the message, optionally in color, with green " | " separating fields, and these fields:
- Severity (e.g. INFO, see
fSeverity
), - Timestamp (e.g. "2020-10-13T16:58:43.982720690+1100", see
fIso8601Tz
), - Thread Id (e.g. "Thread 8", see
fThread
), - Caller (e.g. "MyApp.CLI.cliMain#43", see
fCallerLong
), and - The log message itself.
E.g: "INFO | 2020-10-13T17:06:52.408921221+1100 | Thread 8 | MyApp.CLI.cliMain#43 | MyApp version 0.1.0.0"
The first three columns are fixed-width, which makes visual scanning of the log easier.
renderThreadTimeMessageShort :: LogEnv -> ThreadTimeMessage -> Text Source #
Like renderThreadTimeMessage
, but abbreviate the caller by removing lowercase letters from the module name.
fIso8601Tz :: FormatTime a => (Color -> Builder -> Builder) -> Format r (a -> r) Source #
Render a timestamp in ISO-8601 format, in color, to 9 decimal places, e.g.: "2020-10-13T16:58:43.982720690+1100"
The T is rendered in green, the time in yellow, the rest without color.
fSeverity :: (Color -> Builder -> Builder) -> Format r (Severity -> r) Source #
Render the Severity
of the message, with color, using 4 characters to maintain alignment:
- DBUG in green,
- INFO in blue,
- WARN in yellow, or
- ERR in red.
fThread :: Format r (ThreadId -> r) Source #
Render the Id of the thread that the log message was generated in, with a fixed width, at least until the thread Ids exceed 100,000, e.g. "Thread 97".
fCallerLong :: (Color -> Builder -> Builder) -> Format r (CallStack -> r) Source #
Render the fully qualified function that called the log function, and line number in the source file, e.g. "MyApp.CLI.cliMain#43", with the function name in cyan and line number in red.
fCallerShort :: (Color -> Builder -> Builder) -> Format r (CallStack -> r) Source #
Render the fully qualified function that called the log function, and line number in the source file, abbreviating the module path by removing lower-case letters, e.g. "MA.CLI.cliMain#43", with the function name in cyan and line number in red.
