ore_dict {ore}

Get or set entries in the pattern dictionary

Description

This function allows the user to get or set entries in the pattern dictionary, a library of regular expressions whose elements can be referred to by name in ore, and therefore easily reused.

Usage

ore_dict(..., enclos = parent.frame())

Arguments

...

One or more strings or dictionary keys. Unnamed, literal strings will be returned unmodified, named strings will be added to the dictionary, and unquoted names will be resolved using the dictionary.

enclos

Enclosure for resolving names not present in the dictionary. Passed to eval.

Value

If no arguments are provided, the whole dictionary is returned. Otherwise the return value is a (possibly named) character vector of resolved strings.

# Literal strings are returned as-is
ore_dict("protocol")

# Named arguments are added to the dictionary
ore_dict(protocol="\\w+://")

# ... and can be retrieved by name
ore_dict(protocol)
