Can not generate parsers

ccheraa commented 2 years ago

Problem:

The command grunt parsers is not working as expected

Expected behavior:

Generates JSONiqParser.js and XQueryParser.js

Actual behavior:

Both JSONiqParser.js and XQueryParser.js have the same content:

Usage: REx [OPTION]... [input-file]

  -ll NUM        use strong-LL(K) algorithm up to K=NUM (default 3)
  -backtrack     allow PEG-style backtracking for LL-conflicts

  -cpp           generate parser in C++
  -csharp        generate parser in C#
  -haxe          generate parser in Haxe
  -java          generate parser in Java
  -javascript    generate parser in JavaScript
  -scala         generate parser in Scala
  -typescript    generate parser in TypeScript
  -xquery        generate parser in XQuery
  -xslt          generate parser in XSLT

  -saxon         generate Saxon 10 extension function (requires -java, too)
  -basex         generate BaseX extension function (requires -java, too)

  -xml           create XML representation of grammar
  -asi           handle EcmaScript automatic semicolon insertion (LL(1) only)
  -name NAME     use non-default class name, or XQuery/XSLT module namespace

  -tree          generate code for parse tree or parsing event handler
  -trace         generate code for tokenizer trace
  -main          generate simple main program
  -performance   generate performance test program
  -faster        optimize speed
  -smaller       optimize memory consumption

  -version       show REx version

At first, I was getting a different content, but then I changed: https://github.com/wcandillon/xqlint/blob/10e3885793fe1cd0c8db1c971777549261732184/Gruntfile.js#L23 to

var r = request.post('https://www.bottlecaps.de/rex/', function(err, res, body) {

Also, I set NODE_TLS_REJECT_UNAUTHORIZED=0 because the certificate is apparently expired

The API still seems to be available, do you think it has no a breaking change? Incredible from @GuntherRademacher that this tool is still online after all these year :) This was truly an incredible parser generator, I still think it is :)

Indeed the REx server changed from HTTP to HTTPS some years ago, so the URL change is necessary, Can't see though, why you think the certificate is expired. It's a certificate from Let's Encrypt, the current version was issued July 23rd and is valid through October 21st. The content of the parser files shows a REx usage info. This indicates that the server has received an empty command line, which I think is caused by the request from Gruntfile.js being submitted before it has been equipped with the form data. I have made a change that passes the form data when invoking the request, and sent a pull request: https://github.com/wcandillon/xqlint/pull/109
