Feature Request: Configurable "equality" symbol in production rule #29
Description
Many grammars use different equality symbols to separate the left and right sides of a production rule:
symbol ::= replacement
symbol = replacement
symbol → replacement
If this symbol was configurable, it would make it easier to use these grammars with the tool.

I wonder if it would make sense to attempt to provide a "generic" BNF dialect, where this (and #28 and other aspects) are configurable. This might be enough to deal with W3C, lua, the C standard and a few other "casual" dialects.
The only dialects implemented currently are standardised ones - that is, formally specified by a particular standards body. I've resisted adding an add-hoc dialect, because of course everybody writes theirs differently. Details like escapes within strings get difficult. But I can imagine exposing a bunch of settings like this.
Maybe the syntax is fixed, but the lexing is configurable?

Look here for how this project seems to manage configuration: https://github.com/gotthardp/bnfparser2/tree/master/parser/share/syntax

Also would be nice if
kgtcould support theEBNFsupported by https://www.bottlecaps.de/rr/ui I did converted several (64) grammars to it here https://github.com/mingodad/plgh and would like to have then been managed bykgt
