# A collection of simple regexp-based rules that can be applied to content
# to disambiguate languages with the same file extension.
#
# There two top-level keys: disambiguations and named_patterns.
#
# disambiguations     - a list of disambiguation rules, one for each
#                       extension or group of extensions.
# extensions          - an array of file extensions that this block applies to.
# rules               - list of rules that are applied in order to the content
#                       of a file with matching extension. Rules are evaluated
#                       until one of them matches. If none matches, no language
#                       is returned.
# language            - Language to be returned if the rule matches.
# pattern             - Ruby-compatible regular expression that makes the rule
#                       match. If no pattern is specified, the rule always match.
#                       Pattern can be a string with a single regular expression
#                       or an array of strings that will be merged in a single
#                       regular expression (with union).
# and                 - An and block merges multiple rules and checks that all of
#                       of them must match.
# negative_pattern    - Same as pattern, but checks for absence of matches.
# named_pattern       - A pattern can be reused by specifying it in the
#                       named_patterns section and referencing it here by its
#                       key.
# named_patterns      - Key-value map of reusable named patterns.
#
# Please keep this list alphabetized.
