-- | TOML 1.1.0 parser
--   
--   TOML parser using generated lexers and parsers with careful attention
--   to the TOML 1.1.0 semantics for defining tables.
@package toml-parser
@version 2.0.2.0

-- | This type helps to build up computations that can validate a TOML
--   value and compute some application-specific representation.
--   
--   It supports warning messages which can be used to deprecate old
--   configuration options and to detect unused table keys.
--   
--   It supports tracking multiple error messages when you have more than
--   one decoding option and all of them have failed.
--   
--   Use prettyMatchMessage for an easy way to make human readable
--   strings from matcher outputs.

-- | Computations that result in a Result and which track a list of

-- | A message emitted while matching a TOML value. The message is paired

--   prettyMatchMessage.

--   
--   The table path is the name of the table being sorted. This

-- | Take the first option from a list of table keys and matcher functions.

--   
--   If no keys match, an error message is generated explaining which keys
--   would have been accepted.

--   result of any failure to the next case.

-- | This is the high-level interface to the toml-parser library. It
--   enables parsing, printing, and conversion into and out of
--   application-specific representations.
--   
--   This parser implements TOML 1.1.0 https://toml.io/en/v1.1.0 as
--   carefully as possible.
--   
--   Use Toml.Schema to implement functions mapping between TOML
--   values and your application types.
--   
--   Use Toml.Syntax and Toml.Semantics for low-level TOML
--   syntax processing and semantic validation. Most applications will not
--   need to use these modules directly unless the application is about
--   TOML itself.
--   
--   The types and functions of this package are parameterized over an
--   annotation type in order to allow applications to provide detailed
--   feedback messages tracked back to specific source locations in an
--   original TOML file. While the default annotation is a simple file
--   position, some applications might upgrade this annotation to track
--   multiple file names or synthetically generated sources. Other
--   applications won't need source location and can replace annotations
--   with a simple unit type.
