Conflowio Parsley Versions Save

Package moved from github.com/opsidian/parsley to github.com/conflowio/parsley

OTHER:

• Use Go 1.17
• Add linting using golangci-lint

BACKWARDS INCOMPATIBILITIES:

• Remove Value() from the parsley.Node interface{}, differentiate between literal and non-literal nodes

BACKWARDS INCOMPATIBILITIES:

• Replace Type() string on parsley.Node with Schema() interface{} to support any user-defined schema
• Allow to set schema for nil parser

IMPROVEMENTS:

• Use Go 1.16
• Move tools dependency file to a subpackage

OTHER:

• Remove CodeCov integration

BACKWARDS INCOMPATIBILITIES:

• Remove NL and Whitespaces parsers, these are achievable using the trim parsers
• Change Trim parsers to always skip all whitespaces and return specific whitespace error
• In text.LeftTrim prefer a not found parse error over a whitespace error if the position is the same

IMPROVEMENTS:

• Add struct wrapper for parser functions to allow recursive parser definitions
• Simplify parsley.Error, remove unnecessary msg field (and therefore unnecessary .Error()
• Introduce notfound errors when a parser doesn't match
• Only collect notfound errors in any/choice if they are not in the starting position

BACKWARDS INCOMPATIBILITIES:

• The parsley.Evaluate function doesn't expect an evaluation context anymore, which was renamed to user context to make it more clear and can be set on parsley.Context
• Move ast.WalkNode to parsley.Walk
• The transform functions don't expect a NodeTransformer object anymore (the node transformation must be set on the interpreter)

IMPROVEMENTS:

• The evaluation context is called user context now and can be set on parsley.Context
• Proper recursive static checking (depth-first)
• Proper recursive node transformation support (breadth-first)
• The static checking and transformation are disabled by default and can be enabled on parsley.Context
• Add NodeTransformerRegistry interface

IMPROVEMENTS:

• Add NodeTransformer to context to allow AST transformations
• The StaticChecker helper should not parse the input (minor backward incompatibility)

BUGFIXES:

• Do not panic in StaticCheck if there is no interpreter

IMPROVEMENTS:

• The text types should be constants (e.g. terminal.StringType)

BACKWARDS INCOMPATIBILITIES:

• Rename Substring parser to Op

IMPROVEMENTS:

• Record possible errors in Context if a combinator returns a result for better error messages
