Global A$ = "[" gives missing terminating character "

[rikky]

Hello

I'm using a Fossil from a few days ago.

When I declare a variable A$ = "[" then this works perfectly.
However when I declare it Globally, or Locally in a subroutine it gives an error:

missing terminating character "
Also "abc[123" etc causes this error.

Okee, I'm sorry.

This 'problem is easily solved by NOT taking the shortcut.
So:
GLOBAL Purple$
Purple$ = "\033[0;35m"
Purple , by the way, seems to be a color that has been 'forgotten' in the Bacon colors.

No need to, because you're right: this is a bug. If you would compile with the BaCon shell version then it would be fine. So the problem only occurs in the BaCon version of BaCon.

The fix is available in fossil already. Your workaround also can be used, of course.

This is not true, all ANSI colors are defined. In BaCon, the ANSI sequence "\033[0;35m" is defined as:

COLOR FG TO MAGENTA


Thanks for the bug report!

I've encountered a few more bugs of this kind.
I'm using the latest fossil from just a few moments ago.

GLOBAL A$ = " ASSOC "
GLOBAL A$ = " TYPE "

=> error: expected identifier or '(' before '=' token
and
GLOBAL A$ = " RECORD "
GLOBAL A$ = " ENDRECORD "
GLOBAL A$ = "ENDRECORD "

=> error: expected ':', ',', ';', '}' or '__attribute__' before '=' tokenand
GLOBAL A$ = " ARRAY "

=> missing terminating " characterand
GLOBAL A$ =  " ARRAY  " & \
""
=> Syntax error: string array cannot have more than one dimension

and

GLOBAL A$ = "[]"

and if enclosed

GLOBAL A$ = "[test]"

Thanks guys,

You're recursively testing BaCon code, and the flaws you're running into are caused by code which is there from the very beginning of BaCon (2009).

At the time, the implementation did not have real tokenization functions and had to workaround this limitation by using a plain INSTR.

But now BaCon has matured and actually can tokenize natively

All the aforementioned issues are solved in the latest beta!

Best regards
Peter

One more:
(Using a Fossil from 5 minutes ago.)

GLOBAL bla$ = "["  
GLOBAL blabla$  = "]"
GLOBAL blablabla$  = "="
GLOBAL blablablabla$  = "[]"

GLOBAL bloep$  = "[="
GLOBAL bloepbloep$  = "]="

GLOBAL plop$ = "=["
GLOBAL plopplop$ = "=]"
GLOBAL plopplopplop$ = "=[]"
gives =>

Compilation finished successfully.
but:

GLOBAL bloepbloepbloep$  = "[]="
gives =>

error: missing terminating " character

Dear Rik,

I think that "error" will be very difficult for Peter to replicate. The program compiles fine on Pi4 (Bullseye/Sid) and on Mint 19.2. And it runs without error on both platforms. I wonder whether Joe or Alex have that same problem on Pi3...

With kind regards,

Well, I did a Fossil this morning.
To be sure I am not using some older version, I now use '/home/pi/bacon_trunk/build/bacon'
Chances that Peter accidentally put and old bacon in the Fossil are practically zero.

This is the output:

Hi rikky,

This is an issue with assigning values to strings during initialization. It can be worked around by splitting the code:

GLOBAL plopplopplop$
plopplopplop$ = "=[]"


Anyway, the latest fossil code contains a fix.

Thanks and regards,

Peter
