[2.14] Parsing error not detected with parameters of type VarName
|
This affects both the command line and compiler for scripts.
1. Launch CMud
2. Close Sessions window (ESC)
3. Enter at the command line
| Code: |
| $var="a|b|c";#CALL %vartype($var};#SHOW got here;#IF ($var) {#SHOW yes $var} {#SHOW failed $var} |
You will notice that the 'got here' never gets displayed. This is because of the mismatched parenthesis on %vartype($var}.
4. Open the Package Editor (CTRL-G)
5. Make a new alias, and paste the above command into it script
6. Click save changes, then look at the compiled tab
| Code: |
0000 LITERAL "a|b|c"
0016 ASSIGNLOCAL -1 0
0028 PUSHEXP 0044
0036 JUMP 0084
0044 STR ''
0052 ASSIGNLOCAL -1 0
0064 INT 1
0072 FUNCREF vartype (1)
0084 PUSHSTRLOC 0100
0092 JUMP 0136
0100 STR '#SHOW yes '
0120 LOCAL 0 0
0132 CONCAT
0136 PUSHSTRLOC 0152
0144 JUMP 0192
0152 STR '#SHOW failed '
0176 LOCAL 0 0
0188 CONCAT
0192 CMD call (3) |
This shows that the closing parenthesis of the #IF was used to close the %vartype function. I guess what I am looking for is that it gives a parsing error if there are invalid characters in the VarName parameter, which actually would end up pointing at the brace typo.
The only other function that looks to be affected by this is %pop |

I'll add this to the bug list and see what I can do. It it's easy and doesn't appear to have other side effects, then I might be able to fix it for the public version.
