Show RepoLocation

Defined in Update.Nix.FetchGit.Types

Methods

showsPrec :: Int -> RepoLocation -> ShowS

show :: RepoLocation -> String

showList :: [RepoLocation] -> ShowS

ourParseNixFile :: FilePath -> IO (Either Warning NExprLoc)

extractUrlString :: RepoLocation -> Text

Get the url from either a nix expression for the url or a repo and owner expression.

quoteString :: Text -> Text

extractFuncName :: NExprLoc -> Maybe Text

Given an expression that is supposed to represent a function, extracts the name of the function. If we cannot figure out the function name, returns Nothing.

extractAttr :: Text -> [Binding a] -> Either Warning a

Extract a named attribute from an attrset.

findAttr :: Text -> [Binding a] -> Either Warning (Maybe a)

Find a named attribute in an attrset. This is appropriate for the case when a missing attribute is not an error.

matchAttr :: Text -> Binding a -> Maybe a

Returns 'Just value' if this attribute's key matches the text, otherwise Nothing.

exprText :: NExprLoc -> Either Warning Text

Get the string value of a particular expression, returns a Warning if the expression is not a string value.

TODO: Use evalExpr here

exprSpan :: NExprLoc -> SrcSpan

Get the SrcSpan covering a particular expression.

parseISO8601DateToDay :: Text -> Either Warning Day

formatWarning :: Warning -> String
