- Add a syntax file update to Neville Dempsey's long-serving version - Add a new rudimentary ftplugin - Add filetype detection Changes to the syntax file include: - improved prelude, number and symbol highlighting - prelude highlighting tests - updated boiler plate Note that these runtime files currently target Algol 68 Genie employing the default UPPER stropping regime. Support for GNU Algol 68 should also be usable with the UPPER stropping regime, although somewhat less complete. Full support for the SUPPER stropping regime in GNU Algol 68 is also planned. closes: #19818 Co-authored-by: Doug Kearns <dougkearns@gmail.com> Signed-off-by: Doug Kearns <dougkearns@gmail.com> Signed-off-by: Janis Papanagnou <janis_papanagnou@hotmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
