Grammar railroad diagram

mingodad commented 2 years ago

Based on the code from void Grammar::DisplayInput(void) I built so far this initial EBNF grammar (after some small manual changes) that can be used on https://www.bottlecaps.de/rr/ui to get a railroad diagram (https://en.wikipedia.org/wiki/Syntax_diagram).

I think that it's a useful option to have on LPG2.

Copy and paste the EBNF shown bellow on https://www.bottlecaps.de/rr/ui in the TAB Edit Grammar then switch to the TAB View Diagram.

kuafuwang commented 2 years ago

It's great and useful feature. I love it.

I had implement generate railroad diagram feature on vscode-extension for lpg2 before , but no on LPG2 .Terminal and non-terminal railroad graph for LPG grammars

Can you finish the code which about this feature .

mingodad commented 2 years ago

I need some help understanding the usage of ->, ->?, ::=? and also it seems that LPG2 accepts non alpha characters in identifiers like:

rules_segment ::= RULES_KEY {action_segment}
...
{action_segment} ::= %Empty
{action_segment} ::= {action_segment} action_segment

That makes it trick, probably need a string transformation like I did manually {action_segment} -> action_segment_list.

I could not find a document describing the LPG2 syntax and it's usage (mainly the mentioned ->, ->? and '::=?`). There is any document that describes it ?

kuafuwang commented 2 years ago

It has little document left.in these place. https://github.com/impulse-org/imp.lpg.ide/tree/master/html

produces ::= '::=' produces ::= '::=?' produces ::= '->' produces ::= '->?' i think they are all means produces.no different to us

mingodad commented 2 years ago

I've looked a bit further on this and I decided that LPG2 it's not for me I'll have it as a reference for a LALR(k) parser but I doubt I'll use it due to lack of documentation.

Any way the code that generate the EBNF is on the first message.

That's fine. Than you for you code. About documentation . I will try to write some in future. It's a excellent tool but after Philiphe Charles, Robert M. Fuhrer left IBM,. No one maintain it any more.
