 Posted: Thu Oct 06, 2016 12:42 pm Post subject: Strange behavior of $lua block inside a script's [DISABLE] |
 |
|
I'm doing some cleanup in the DISABLE section of a script, restoring original values. The resulting script works as expected, however there's an issue during authoring: when saving the script into the table, CE shows a warning message box ("Not all code is injectable. (Failure determining what L means)").
Here's the simplified script:
| Code: |
[ENABLE]
alloc(M,1024)
label(L)
registersymbol(L)
L:
[DISABLE]
{$lua}
getAddress("L")
{$asm}
unregistersymbol(L)
dealloc(M,1024)
|
If I were to change the LUA code to, say:
| Code: |
if (false) then
getAddress("L")
end
|
The script saves fine, with no warnings, so it seems that CE is trying to _execute_ LUA code in the DISABLE section on saving instead of just parsing it. As I said before, the _original_ script works properly once saved, as by the time DISABLE section actually gets control the symbol is registered by the ENABLE section.
I thus have two questions:
1. Why is this happening to me?
2. How can I work around this?
Random thoughts:
* Ignoring the warning doesn't do it for me, as it may complicate finding actual errors in the script.
* getSymbolInfo() apparently returns nil for user-defined symbols, so it doesn't help here.
* I don't like clutter, so I don't want to have symbols permanently registered.
* errorOnLookupFailure() sort of helps, but it seems to be per-process, so I'd rather not, also it still doesn't solve the issue of the code getting executed on save.

when you click ok it runs the script to check for errors. (and some scripts generate important code required for the resg of the script)
you can use syntaxcheck to see if it should act or not
add this line as first line of each lua section
| Code: |
if syntaxcheck then return end

Ah, that explains it, and I was hoping for something like this. Thanks.
As a side note: CE's feature set is superb, feature discoverability — not so much. Sorry, had to say it.
