Running

TPyParser.findAllErrors("{1:1=")

uses 100% of a core and then crashes the Chrome tab.

This was stripped down from something slightly more meaningful, but still invalid Python!

Running the same in NodeJS it's a bit clearer that it fails by running out of memory.

I have integrated TigerPython-Parser into a Python learning game.
I would like to be able to modify some error messages in French. But the setErrorMessage method does not work for the French language. As shown in the code below quoted from ErrorTranslator.scala

override def setMessage(code: ErrorCode.Value, msg: String): Boolean =
  _lang match {
    case "de" =>
      errormessages.GermanMessages.setMessage(code, msg)
      true
    case "en" =>
      errormessages.EnglishMessages.setMessage(code, msg)
      true
    case _ =>
      false
  }

}

Then how can I change these messages?

Thank you in advance,

Hi Tobias,

When testing my application in the classroom, one student encountered this problem:

I unfortunately don't have the Python code that caused the error, but if the error comes back, I will try to collect the Python code that causes this problem.

Any idea of what the problem is? Maybe a recurring call with no break cases?

Thks,

Matthieu

One common mistake for the novices, at least in french speaking part of switzerland, is to use the comma instead of the . for floating point literals. This is because we say "nombre à virgule" to denote numbers with decimal positions. This generates errors really difficult to decrypt for the novices

from gturtle import *
makeTurtle()

size = 10
for _ in range(10):
    fd(size)
    rt(360 / 6)

    size *= 1,2

Context: TigerPython is used in a Vue project. I am calling the parser to get the python AST of some small code portions.

When the parser finds a comparison, the returned expression object contains a left property that I can access. However, the comparators and ops properties cannot be accessed, because I get the following error : "Exception: TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode functions or the arguments objects for calls to them at Function.r"

The Python grammar allows underscores in the number litterals to increase readability. For instance, Python accepts litterals like 1_000_000 for 1 million. It would be great if the parser would accept that syntax.

I don't know what they currently do for syntax checking but I suspect they didn't hire a Ph.D. to do it. :-)
