We currently uses pegjs
with phpegjs
to generate the php parser which parses TQL queries to its AST.
But phpegjs
is no longer maintained since 2021 and recommend to use phpeggy
instead.
phpeggy
is a plugin of peggy
which is described as the successor of pegjs
.
Fortunately both libraries are compatible with peg syntax so we don't have to rewrite full grammar specification.
