- peekVersionFuzzy :: LuaError e => Peeker e Version

# Module

documentedModule :: LuaError e => Module e #

The `path` module specification.

# Version objects

typeVersion :: LuaError e => DocumentedTypeWithList e Version Int #

Type definition of Lua Version values.

peekVersion :: LuaError e => Peeker e Version #

Retrieve a ``Version`` object from the top of the stack.

pushVersion :: LuaError e => Pusher e Version #

Push a ``Version`` element to the Lua stack.

peekVersionFuzzy :: LuaError e => Peeker e Version #

Retrieve a Version-like object from the top of the stack.

This function uses these heuristics, depending on the Lua object type.

- string: object is parsed as a version specifier.
- table: value is expected to be a list of integers, with each index specifying a version branch.
- userdata: assumes the value to be a Version userdata object.
- number: parses the number as an integer value.

Otherwise, or if the object fails to meet an expectation, peeking fails.
