newtype PSCiConfig Source #
The PSCI configuration.
These configuration values do not change during execution.

Defined in Language.PureScript.Interactive.Types Methods showsPrec :: Int -> PSCiConfig -> ShowS # show :: PSCiConfig -> String # showList :: [PSCiConfig] -> ShowS # | |
The PSCI state.
Holds a list of imported modules, loaded files, and partial let bindings, plus the currently configured interactive printing function.
The let bindings are partial, because it makes more sense to apply the binding to the final evaluated expression.
The last two fields are derived from the first three via updateImportExports each time a module is imported, a let binding is added, or the session is cleared or reloaded
type ImportedModule = (ModuleName, ImportDeclarationType, Maybe ModuleName) Source #
All of the data that is contained by an ImportDeclaration in the AST. That is:
- A module name, the name of the module which is being imported
- An ImportDeclarationType which specifies whether there is an explicit import list, a hiding list, or neither.
- If the module is imported qualified, its qualified name in the importing module. Otherwise, Nothing.
psciExports :: PSCiState -> Exports Source #
psciImports :: PSCiState -> Imports Source #
psciLoadedExterns :: PSCiState -> [(Module, ExternsFile)] Source #
psciInteractivePrint :: PSCiState -> (ModuleName, Ident) Source #
psciLetBindings :: PSCiState -> [Declaration] Source #
initialInteractivePrint :: (ModuleName, Ident) Source #
The default interactive print function.
updateImportedModules :: ([ImportedModule] -> [ImportedModule]) -> PSCiState -> PSCiState Source #
Updates the imported modules in the state record.
updateLoadedExterns :: ([(Module, ExternsFile)] -> [(Module, ExternsFile)]) -> PSCiState -> PSCiState Source #
Updates the loaded externs files in the state record.
updateLets :: ([Declaration] -> [Declaration]) -> PSCiState -> PSCiState Source #
Updates the let bindings in the state record.
setInteractivePrint :: (ModuleName, Ident) -> PSCiState -> PSCiState Source #
Replaces the interactive printing function in the state record with a new one.
