Grammar railroad diagram

[mingodad]

Transforming a bit the grammar at https://github.com/ELENA-LANG/elena-lang/blob/develop/dat/sg/syntax60.txt to an EBNF accepted by (IPV4) https://rr.red-dove.com/ui or (IPV6) https://www.bottlecaps.de/rr/ui (repository here https://github.com/GuntherRademacher/rr) we can have a nice navigable railroad diagram (see instructions bellow at the top).

Ideally the sg application could output it as an option.

I think that it's a valuable option to document/debug/develop the grammar.

The ÈBNF shown bellow was hand transformed by removing the __define lines, replace {} by (), {}* by ()*, {}+ by ()+, {}? by ()?, ^ANY by `/*^ANY*/ and removing the ';' rule/production separator.

//
// EBNF to be viewd at

// Copy and paste this at one url shown above in the 'Edit Grammar' tab
