Arguments
| :: GhcMonad m | |
| => String | a statement (bind or expression) |
| -> ExecOptions | |
| -> m ExecResult |
Run a statement in the current interactive context.
execStmt' :: GhcMonad m => GhciLStmt GhcPs -> String -> ExecOptions -> m ExecResult Source #
Like execStmt, but takes a parsed statement as argument. Useful when
doing preprocessing on the AST before execution, e.g. in GHCi (see
GHCi.UI.runStmt).

resumeExec :: GhcMonad m => (SrcSpan -> Bool) -> SingleStep -> Maybe Int -> m ExecResult Source #
runDeclsWithLocation :: GhcMonad m => String -> Int -> String -> m [Name] Source #
Run some declarations and return any user-visible names that were brought into scope.
runParsedDecls :: GhcMonad m => [LHsDecl GhcPs] -> m [Name] Source #
Like runDeclsWithLocation, but takes parsed declarations as argument.
Useful when doing preprocessing on the AST before execution, e.g. in GHCi
(see GHCi.UI.runStmt).

abandonAll :: GhcMonad m => m Bool Source #
getResumeContext :: GhcMonad m => m [Resume] Source #
getModBreaks :: HomeModInfo -> ModBreaks Source #
getHistoryModule :: History -> Module Source #
setContext :: GhcMonad m => [InteractiveImport] -> m () Source #
Set the interactive evaluation context.
(setContext imports) sets the ic_imports field (which in turn
determines what is in scope at the prompt) to imports, and
constructs the ic_rn_glb_env environment to reflect it.
We retain in scope all the things defined at the prompt, and kept in ic_tythings. (Indeed, they shadow stuff from ic_imports.)
getContext :: GhcMonad m => m [InteractiveImport] Source #
Get the interactive evaluation context, consisting of a pair of the set of modules from which we take the full top-level scope, and the set of modules from which we take just the exports respectively.
getNamesInScope :: GhcMonad m => m [Name] Source #
Returns all names in scope in the current interactive context
getRdrNamesInScope :: GhcMonad m => m [RdrName] Source #
Returns all RdrNames in scope in the current interactive
context, excluding any that are internally-generated.
moduleIsInterpreted :: GhcMonad m => Module -> m Bool Source #
Returns True if the specified module is interpreted, and hence has
its full top-level scope available.
getInfo :: GhcMonad m => Bool -> Name -> m (Maybe (TyThing, Fixity, [ClsInst], [FamInst], SDoc)) Source #
Looks up an identifier in the current interactive context (for :info) Filter the instances by the ones whose tycons (or clases resp) are in scope (qualified or otherwise). Otherwise we list a whole lot too many! The exact choice of which ones to show, and which to hide, is a judgement call. (see #1581)
exprType :: GhcMonad m => TcRnExprMode -> String -> m Type Source #
Get the type of an expression
Returns the type as described by TcRnExprMode
parseName :: GhcMonad m => String -> m [Name] Source #
Parses a string as an identifier, and returns the list of Names that
the identifier can refer to in the current interactive context.
getDocs :: GhcMonad m => Name -> m (Either GetDocsFailure (Maybe HsDocString, IntMap HsDocString)) Source #
data GetDocsFailure Source #
Failure modes for getDocs.

moduleIsBootOrNotObjectLinkable :: GhcMonad m => ModSummary -> m Bool Source #
parseExpr :: GhcMonad m => String -> m (LHsExpr GhcPs) Source #
Parse an expression, the parsed expression can be further processed and passed to compileParsedExpr.
compileExpr :: GhcMonad m => String -> m HValue Source #
Compile an expression, run it, and deliver the resulting HValue.
dynCompileExpr :: GhcMonad m => String -> m Dynamic Source #
Compile an expression, run it and return the result as a Dynamic.
compileExprRemote :: GhcMonad m => String -> m ForeignHValue Source #
Compile an expression, run it, and deliver the resulting HValue.
compileParsedExprRemote :: GhcMonad m => LHsExpr GhcPs -> m ForeignHValue Source #
Compile a parsed expression (before renaming), run it, and deliver the resulting HValue.
