ParseExpression parses a single River expression from expr.

If an error was encountered during parsing, the returned expression will be nil and err will be an ErrorList with all the errors encountered during parsing.

func ParseFile

func ParseFile(filename string, data []byte) (*ast.File, error)

ParseFile parses an entire River configuration file. The data parameter should hold the file contents to parse, while the filename parameter is used for reporting errors.

If an error was encountered during parsing, the returned AST will be nil and err will be an diag.Diagnostics all the errors encountered during parsing.
