Rasa.Internal.BufAction

Synopsis

Documentation

This is a monad for performing actions on a specific buffer. You run BufActions by embedding them in a Action via bufferDo or buffersDo

Within a BufAction you can:

Use liftAction to run an Action
Use liftIO for IO
Access/Edit the buffer's text; some commands are available in Rasa.Internal.Actions.
Access/edit buffer extensions; see bufExt
Embed and sequence BufActions from other extensions

Returns the text of the current buffer

Sets the text of the current buffer

Gets the current buffer's BufRef

Gets the range of text from the buffer

Sets the range of text from the buffer

Retrieve some buffer extension state

Set some buffer extension state

overBufExt :: (Typeable ext, Show ext, Default ext) => (ext -> ext) -> BufAction () Source #

Set some buffer extension state

This lifts up an Action to be run inside a BufAction
