This change extends --map-<LANG> option to support regular expression matching with the full file name. The original --map-<LANG> option supports glob based matching and extension comparison with the file basename. However, two methods are not enough if the file names are too generic. See universal-ctags#3287 . The regular expression passed to --map-<LANG> must be surround by % character like --map-RpmMacros='%(.*/)?macros\.d/macros\.([^/]+)$%' If you want to match in a case-insensitive way, append `i' after the second % like --map-RpmMacros='%(.*/)?macros\.d/macros\.([^/]+)$%i' If you want to use % as part of an expression, put \ before % for escaping.

main: using regex for choosing a parser for the given file name
This change extends --map- option to support regular
expression matching with the full file name.
The original --map- option supports glob based matching
and extension comparison with the file basename.
However, two methods are not enough if the file names are too
generic. See #3287 .
The regular expression passed to --map- must be surround
by % character like
--map-RpmMacros='%(.*/)?macros.d/macros.([^/]+)$%'
If you want to match in a case-insensitive way, append `i' after the second % like
--map-RpmMacros='%(.*/)?macros.d/macros.([^/]+)$%i'
If you want to use % as part of an expression, put \ before % for escaping.
