Thread: Grammar railroad diagram

I've done a experimental tool to convert bison grammars to a kind of EBNF understood by https://www.bottlecaps.de/rr/ui to generate railroad diagrams see bellow the converted 'postgresql-13.3/src/backend/parser/gram.y' and with some hand made changes to allow view it at https://www.bottlecaps.de/rr/ui the order of the rules could be changed to a better view of the railroad diagrams. Copy and paste the EBNF bellow on https://www.bottlecaps.de/rr/ui tab Edit Grammar then switch to the tab View Diagram.

That is pretty cool.  I had trouble figuring out how to get it working,
so here are the steps I used:

    1.  save my attachment (created by Domingo)
    2.  go to https://www.bottlecaps.de/rr/ui
    3.  select "Edit Grammar"
    4.  choose "Browse" at the bottom
    5.  select the attachment you saved in #1
    6.  choose "Load" at the bottom
    7.  select "View Diagram"

You can even click on the yellow boxes to see the sub-grammar.  People
have asked for railroad diagrams in the past, and this certainly
produces them, and "Options" allows many customizations.

I tried downloading as XHTML+SVG and HTML+PNG but got an error:

    HTTP Status 500 – Internal Server Error

    Type Exception Report
    
    Message The multi-part request contained parameter data (excluding
    uploaded files) that exceeded the limit for maxPostSize set on the
    associated connector
    
    Description The server encountered an unexpected condition that
    prevented it from fulfilling the request.

It might be nice to download this output and host it on the Postgres
website at some point.

Hello Bruce !

You can download the railroad generator to generate offline using Java 
here -> https://www.bottlecaps.de/rr/download/rr-1.63-java8.zip (link 
from the https://www.bottlecaps.de/rr/ui on tab Welcome).

java -jar rr.war -out:Dafny.atg.xhtml grammar.txt

Cheers !

Hi,

It'd be nice if you could share that tool. The diagrams this can generate
are neat...

Greetings,

Andres Freund

Hello Andres !

There is two ways to achieve it:

-1 I just add the bison grammar in CocoR format here 
https://github.com/mingodad/CocoR-CPP in the examples folder.

-2 I created an small extension to Bison to do the same and published 
the patch here 
https://github.com/mingodad/bison/commit/da84329ebe5f4bc111ef34b2d46088b655a217f3 
(bison -e yourgramar.y)

And optionally to have the best railroad diagram we need to add the 
"Tokens" manually.

Cheers !

Hello Andres !

Another way that I tested and it's working is to use 
https://www.bottlecaps.de/convert/ paste the postgresql grammar there 
and press "convert" and after press "view diagram".

Again optionally manually add the Tokens to a better diagram !

====

// Tokens from postgresql-13.3/src/include/parser/kwlist.h

ABORT_P ::= "abort"
ABSOLUTE_P ::= "absolute"
ACCESS ::= "access"
ACTION ::= "action"
