I am new to computercraft and have a problem with my code.
The error is
'=' expected near 'monitor'
Do anyone know the problem and can fix it?

In Lua interpreter when I type
>print (12
>>3)
stdin:2: ')' expected (to close '(' at line 1) near '3'
Why am I getting this error?
When we type
>a=2
>a=a+
>>1
This works fine! Then why not print? What is wrong with print()?
The input is print (12 <NEWLINE> 3), which is a syntax error.
Adding a comma after 12 works fine.
So I'm starting to Learn Lua, my problem is that in a tutorial that teaches you to create Guess My Number Game starts with this line:
name = "John"
print<name>
So in the tutorial shows that prints the name but in mine gives this error:
stdin:1: '=' expected near '<'
Please, what am I getting this?
Thank you for all your help.
Functions use parentheses to enclose their arguments, so the second line should be
print (name)
I'm incredibly new to C and Xcode in general. Could somebody explain why this isn't working, and how to fix it?
You have a number of issues.
Regarding the Expected Expression error, you declared _declination and _latitude as UITextField. To get the integer value, you can use: _declination.text.intValue. In context:
if (_declination.text.intValue >= 90 - _latitude.text.intValue)
Regarding Missing terminating character " you need to change:
#The star is circumpolar"
to:
#"The star is circumpolar"
You are missing a quote:
"The star is circumpolar!"
Does any one knows if there is an ErrorStrategy on Antlr4.4 to continue parsing after an error is found, i need to show all the errors found in the program but Antlr stop parsing after the first error is found, im using the DefaultErrorStrategy.
This is my input, I should get error ond line 2 3 and 6 but it only reports the error on line 2.
class Program {
bool
bool test
int prueba ;
int prueba ;
int test;
bool prueba
}
The error is:
line 2:1 mismatched input 'bool' expecting {'boolean', 'int', 'void', '}'}
bool
^^^^
Antlr 4's parser error strategy is to drop tokens from the input until it can detect a sane state and then it continues parsing. Looking at your example, while trying to recover maybe it never reaches a sane state before EOF.
Seems like antlr can't recover if there are 2 contiguous error in the program. If the errors are not contiguous it works fine. Thank you very much for your help.
I'm writing a parser for a very simple grammar in javacc. It's beginning to come together but at the moment I'm completely stuck on this error:
ParseException: Encountered "" at line 4, column 15.
Was expecting one of:
The line of input in question is z = y + z + 5
and the production that is giving me problems is my expression which get called from
varDecl():
<ID> <EQL> expression()
Expression looks like this:
<VAR> (<PLUS> expression())?| <NUM> (<PLUS> expression())?
| call() (<PLUS> expression())?
I'm at a loss as to why I'm getting this error - any insight would be greatly appreciated.
Hm, yes, that's not a very helpful error from JavaCC. What version of JavaCC are you using?
Also, it's difficult to troubleshoot these problems without seeing the full grammar... and although I understand you might not be in a position to post that.
