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

extractUrlString :: RepoLocation -> Text Source #

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

quoteString :: Text -> Text Source #

extractFuncName :: NExprLoc -> Maybe Text Source #

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 Source #

Extract a named attribute from an attrset.

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

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 Source #

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

exprText :: NExprLoc -> Either Warning Text Source #

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 Source #

Get the SrcSpan covering a particular expression.

parseISO8601DateToDay :: Text -> Either Warning Day Source #

formatWarning :: Warning -> String Source #
