data CommandState

Auxiliary state of an interactive computation.

Constructors

CommandState

Fields

• theInteractionPoints :: [InteractionId]

  The interaction points of the buffer, in the order in which they appear in the buffer. The interaction points are recorded in theTCState, but when new interaction points are added by give or refine Agda does not ensure that the ranges of later interaction points are updated.

• theCurrentFile :: Maybe (AbsolutePath, ClockTime)

  The file which the state applies to. Only stored if the module was successfully type checked (potentially with warnings). The ClockTime is the modification time stamp of the file when it was last loaded.

• optionsOnReload :: CommandLineOptions

  Reset the options on each reload to these.

• oldInteractionScopes :: !OldInteractionScopes

  We remember (the scope of) old interaction points to make it possible to parse and compute highlighting information for the expression that it got replaced by.

type OldInteractionScopes = Map InteractionId ScopeInfo

initCommandState :: CommandState

Initial auxiliary interaction state

type CommandM = StateT CommandState TCM

Monad for computing answers to interactive commands.

CommandM is TCM extended with state CommandState.

revLift

Arguments

:: MonadState st m

=> (forall c. m c -> st -> k (c, st))

run

-> (forall b. k b -> m b)

lift

-> (forall x. (m a -> k x) -> k x)

-> m a

reverse lift in double negative position

Build an opposite action to lift for state monads.

commandMToIO :: (forall x. (CommandM a -> IO x) -> IO x) -> CommandM a

Opposite of liftIO for CommandM. Use only if main errors are already catched.

liftCommandMT :: (forall a. TCM a -> TCM a) -> CommandM a -> CommandM a

Lift a TCM action transformer to a CommandM action transformer.

putResponse :: Response -> CommandM ()

Put a response by the callback function given by stInteractionOutputCallback.

modifyTheInteractionPoints :: ([InteractionId] -> [InteractionId]) -> CommandM ()

A Lens for theInteractionPoints.

Operations for manipulating oldInteractionScopes.

modifyOldInteractionScopes :: (OldInteractionScopes -> OldInteractionScopes) -> CommandM ()

A Lens for oldInteractionScopes.

insertOldInteractionScope :: InteractionId -> ScopeInfo -> CommandM ()

removeOldInteractionScope :: InteractionId -> CommandM ()

getOldInteractionScope :: InteractionId -> CommandM ScopeInfo

handleCommand_ :: CommandM () -> CommandM ()

Do setup and error handling for a command.

handleCommand :: (forall a. CommandM a -> CommandM a) -> CommandM () -> CommandM () -> CommandM ()

runInteraction :: IOTCM -> CommandM ()

Run an IOTCM value, catch the exceptions, emit output

If an error happens the state of CommandM does not change, but stPersistent may change (which contains successfully loaded interfaces for example).

type Interaction = Interaction' Range

An interactive computation.

data Interaction' range

Constructors

Cmd_load FilePath [String]

cmd_load m argv loads the module in file m, using argv as the command-line options.

Cmd_compile Backend FilePath [String]

cmd_compile b m argv compiles the module in file m using the backend b, using argv as the command-line options.

Cmd_constraints

Cmd_metas

Show unsolved metas. If there are no unsolved metas but unsolved constraints show those instead.

Cmd_show_module_contents_toplevel Rewrite String

Shows all the top-level names in the given module, along with their types. Uses the top-level scope.

Cmd_search_about_toplevel Rewrite String

Shows all the top-level names in scope which mention all the given identifiers in their type.

Cmd_solveAll

Cmd_infer_toplevel Rewrite String

Parse the given expression (as if it were defined at the top-level of the current module) and infer its type.

Cmd_compute_toplevel Bool String

Parse and type check the given expression (as if it were defined at the top-level of the current module) and normalise it.

Cmd_load_highlighting_info FilePath

cmd_load_highlighting_info source loads syntax highlighting information for the module in source, and asks Emacs to apply highlighting info from this file.

If the module does not exist, or its module name is malformed or cannot be determined, or the module has not already been visited, or the cached info is out of date, then no highlighting information is printed.

This command is used to load syntax highlighting information when a new file is opened, and it would probably be annoying if jumping to the definition of an identifier reset the proof state, so this command tries not to do that. One result of this is that the command uses the current include directories, whatever they happen to be.

Cmd_highlight InteractionId range String

Tells Agda to compute highlighting information for the expression just spliced into an interaction point.

ShowImplicitArgs Bool

Tells Agda whether or not to show implicit arguments.

ToggleImplicitArgs

Toggle display of implicit arguments.

Cmd_give InteractionId range String

If the range is noRange, then the string comes from the minibuffer rather than the goal.
