Constructors

ParsingEnv

Fields

uniqueNames :: UniqueName
uniqueTypeGuid :: Name -> m (Maybe Text)
Return a GUID to reuse for a unique type of the given name, if any.
This callback is called for every `unique type` declaration that does not explicitly specify a GUID.
The name (e.g. Foo in `unique type Foo`) is passed in, and if the function returns a Just, that GUID is used; otherwise, a random one is generated from $sel:uniqueNames:ParsingEnv.

anyToken :: Ord v => P v m (Token Lexeme) Source #

blank :: Ord v => P v m (Token NameSegment) Source #

Parse a placeholder or typed hole

bytesToken :: Ord v => P v m (Token Bytes) Source #

chainl1 :: Ord v => P v m a -> P v m (a -> a -> a) -> P v m a Source #

Parse p 1+ times, combining with op

chainr1 :: Ord v => P v m a -> P v m (a -> a -> a) -> P v m a Source #

chainl1Accum :: (Stream u, Ord s) => ParsecT s u m a -> ParsecT s u m (a -> a -> a) -> ParsecT s u m (a, [a -> a]) Source #

character :: Ord v => P v m (Token Char) Source #

closeBlock :: Ord v => P v m (Token ()) Source #

Consume the end of a block

optionalCloseBlock :: Ord v => P v m (Token ()) Source #

With layout, blocks might “close” without an explicit outdent (e.g., not even a newline at the end of a Transclude). This allows those blocks to be closed by EOF.

doc :: Ord v => P v m (Token (UntitledSection (Tree (Token (ReferenceType, HashQualified Name)) [Token Lexeme]))) Source #

failCommitted :: Ord v => Error v -> P v m x Source #

failureIf :: Ord v => P v m (P v m b) -> P v m a -> P v m b Source #

If p would succeed, this fails uncommitted. Otherwise, failIfOk used to produce the output

hqInfixId :: Ord v => P v m (Token (HashQualified Name)) Source #

hqPrefixId :: Ord v => P v m (Token (HashQualified Name)) Source #

importSymbolyId :: Ord v => P v m (Token Name) Source #

The + in: use Foo.bar + as a Name

importWordyId :: Ord v => P v m (Token Name) Source #

Parse a wordyId as a Name, rejecting any hash

label :: (Ord v, Show a) => String -> P v m a -> P v m a Source #

matchToken :: Ord v => Lexeme -> P v m (Token Lexeme) Source #

Match a particular lexeme exactly, and consume it.

mkAnn :: (Annotated a, Annotated b) => a -> b -> Ann Source #

numeric :: Ord v => P v m (Token String) Source #

openBlock :: Ord v => P v m (Token String) Source #

Consume a block opening and return the string that opens the block.

openBlockWith :: Ord v => String -> P v m (Token ()) Source #

peekAny :: Ord v => P v m (Token Lexeme) Source #

positionalVar :: (Annotated a, Var v) => a -> v -> v Source #

Gives this var an id based on its position - a useful trick to obtain a variable whose id won't match any other id in the file `positionalVar a Var.missingResult`

prefixDefinitionName :: Var v => P v m (Token v) Source #

Parse a prefix identifier e.g. Foo or (+), discarding any hash

prefixTermName :: Var v => P v m (Token v) Source #

Parse a prefix identifier e.g. Foo or (+), rejecting any hash This is useful for term declarations, where type signatures and term names should not have hashes.

queryToken :: Ord v => (Lexeme -> Maybe a) -> P v m (Token a) Source #

Virtual pattern match on a lexeme.

reserved :: Ord v => String -> P v m (Token String) Source #

Parse a reserved word

root :: Ord v => P v m a -> P v m a Source #

rootFile :: Ord v => P v m a -> P v m a Source #

run' :: (Monad m, Ord v) => P v m a -> String -> String -> ParsingEnv m -> m (Either (Err v) a) Source #

sepBy1 :: Ord v => P v m a -> P v m b -> P v m [b] Source #

string :: Ord v => P v m (Token Text) Source #

symbolyDefinitionName :: Var v => P v m (Token v) Source #

Parse a symboly ID like >>= or &&, discarding any hash

tok :: (Ann -> a -> b) -> Token a -> b Source #

tokenToPair :: Token a -> (Ann, a) Source #

tupleOrParenthesized :: Ord v => P v m a -> (Ann -> a) -> (a -> a -> a) -> P v m (Ann, a) Source #

Parses a tuple of as, or a single parenthesized a

returns the result of combining elements with pair, alongside the annotation containing the full parenthesized expression.

uniqueBase32Namegen :: forall gen. DRG gen => gen -> UniqueName Source #

uniqueName :: (Monad m, Var v) => Int -> P v m Text Source #

wordyDefinitionName :: Var v => P v m (Token v) Source #
