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 1.0.0 https://toml.io/en/v1.0.0 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.
TOML 1.0.0 parser TOML parser using generated lexers and parsers with careful attention to the TOML 1.0.0 semantics for defining tables.
TOML format parser compliant with v1.0.0. See README.md for more details.
Alternative parser for TOML values produced by the toml-reader package. Package defines a set of parser combinators that allows analyzing arbitrary TOML structures. Includes formatted errors that keep track of where in the original TOML file a value came from.
