State

Fields

state_filter :: Filter
state_catch_patterns :: [CatchPattern]
Msgs matching this regex have their matching groups put in the status line.
state_status :: Status
state_cached_msgs :: Sequence.Seq Log.Msg
A cache of the most recent msgs. When the filter is changed they can be displayed. This way memory use is bounded but you can display recent msgs you missed because of the filter.
state_last_displayed :: Maybe (Log.Msg, Int)
Last displayed msg, along with the number of times it has been seen. Used to suppress duplicate msgs.

Instances

Instances details

Show State Source #
Instance details Defined in LogView.Process Methods showsPrec :: Int -> State -> ShowS # show :: State -> String # showList :: [State] -> ShowS #

initial_state :: Text -> State Source #

add_msg :: Int -> Log.Msg -> State -> State Source #

state_msgs :: State -> [Log.Msg] Source #

compile_filter :: Text -> Filter Source #

Compile a simple filter language. A log msg matches if all of the words in the filter occur within its Log.msg_text, and none of the words prefixed by - occur.

process_msg

process_msg :: State -> Log.Msg -> (Maybe StyledText, State) Source #

Process an incoming log msg. If the msg isn't filtered out, returned a colorized version. Also possibly modify the app state for things like catch and timing.

type CatchPattern = (Text, Regex.Regex) Source #

Extract text from a log msg and put it in state_status, via catch_regexes.

global_status_pattern :: CatchPattern Source #

This catches msgs emitted by set_global_status.

render_status :: Status -> StyledText Source #

data StyledText Source #

Constructors

StyledText
Fields style_text :: B.ByteString UTF8-encoded text. style_style :: B.ByteString `Style` characters, same length as style_text.
