Ide.Logger

Description

This is a compatibility module that abstracts over the concrete choice of logging framework so users can plug in whatever framework they want to.

data Priority #

Constructors

Debug	Verbose debug logging.
Info	Useful information in case an error has to be understood.
Warning	These error messages should not occur in a expected usage, and should be investigated.
Error	Such log messages must never occur in expected usage.

newtype Logger #

Note that this is logging actions _of the program_, not of the user. You shouldn't call warning/error if the user has caused an error, only if our code has gone wrong and is itself erroneous (e.g. we threw an exception).

Functor WithPriority #
Instance details Defined in Ide.Logger Methods fmap :: (a -> b) -> WithPriority a -> WithPriority b # (<$) :: a -> WithPriority b -> WithPriority a #

logWith :: (HasCallStack, MonadIO m) => Recorder (WithPriority msg) -> Priority -> msg -> m () #

cmap :: (a -> b) -> Recorder b -> Recorder a #

cmapIO :: (a -> IO b) -> Recorder b -> Recorder a #

cfilter :: (a -> Bool) -> Recorder a -> Recorder a #

withFileRecorder #

Arguments

:: MonadUnliftIO m
=> FilePath	Log file path.
-> Maybe [LoggingColumn]	logging columns to display. `Nothing` uses `defaultLoggingColumns`
-> (Either IOException (Recorder (WithPriority (Doc d))) -> m a)	action given a recorder, or the exception if we failed to open the file
-> m a

makeDefaultStderrRecorder :: MonadIO m => Maybe [LoggingColumn] -> m (Recorder (WithPriority (Doc a))) #

makeDefaultHandleRecorder #

Arguments

:: MonadIO m
=> Maybe [LoggingColumn]	built-in logging columns to display. Nothing uses the default
-> Lock	lock to take when outputting to handle
-> Handle	handle to output to
-> m (Recorder (WithPriority (Doc a)))

data LoggingColumn #

Constructors

TimeColumn
ThreadIdColumn
PriorityColumn
DataColumn
SourceLocColumn

cmapWithPrio :: (a -> b) -> Recorder (WithPriority b) -> Recorder (WithPriority a) #

withBacklog :: (v -> Recorder a) -> IO (Recorder a, v -> IO ()) #

Given a Recorder that requires an argument, produces a Recorder that queues up messages until the argument is provided using the callback, at which point it sends the backlog and begins functioning normally.

lspClientMessageRecorder :: LanguageContextEnv config -> Recorder (WithPriority Text) #

Creates a recorder that sends logs to the LSP client via window/showMessage notifications.

lspClientLogRecorder :: LanguageContextEnv config -> Recorder (WithPriority Text) #

Creates a recorder that sends logs to the LSP client via window/logMessage notifications.

module Prettyprinter

renderStrict :: SimpleDocStream ann -> Text #

(renderStrict sdoc) takes the output sdoc from a rendering function and transforms it to strict text.

toCologActionWithPrio :: (MonadIO m, HasCallStack) => Recorder (WithPriority msg) -> LogAction m (WithSeverity msg) #
