[2.08] Expression trigger bug
|
| Quote: |
<class name="Test" id="1">
<trigger type="Expression" priority="20" id="2">
<pattern>@testvar=1</pattern>
<value>#SHOW Testvar now equals @testvar, and it SHOULD equal 1</value>
</trigger>
<var name="testvar" id="3">0</var>
</class> |
1. Blank settings file, by hitting ESC from char selection screen.
2. Create the quoted settings.
3. Enter "testvar=1" to command line. Nothing happens.
4. Enter "testvar=0" to command line. Following line is displayed:
Testvar now equals 1, and it SHOULD equal 1
5. Show mild surprise. Enter "#sh @testvar" to command line. Following is displayed:
0
6. Show more surprise :D |

Well, this is definitely a weird one.
After creating the trigger, click on the "Compiled Pattern" tab to see the code:
| Code: |
0000 VARREF @testvar <testvar> (class untitled)
0024 INT 1
0032 NEQ |
Notice surprise when you see the last operator is "NEQ" which is the "not-equal-to" operator instead of the expected "EQ" operator! Obviously a bad parser bug. Should be fixed in 2.09 later tonight. |

OK, that was actually just a bug in the display of the disassembler...all of the operators AND, OR, XOR, LT, LE, GT, GE, EQ, NEQ were off by one. But it was still performing the EQ operation even though it showed NEQ, so that isn't the problem causing this expression trigger not to work. Still looking.
