Check a Cronus Zen script
Paste a GPC script or open a .gpc file. You get a plain-English list of problems, each with its line and how to fix it, before you compile it in Zen Studio.
Private: the check runs entirely in your browser. Your script is never uploaded or stored, and it's gone when you close the page.
Results
No script yet
Paste a script on the left, open a .gpc file, or try the example.
What it checks
Syntax
Missing or extra { } and ( ), missing semicolons, unexpected words, and code outside of any block.
Names
Variables used but never declared, typos in function and combo names, duplicates, and wrong numbers of arguments.
Limits
Numbers too big for GPC, save slots past SPVAR_64, const arrays that overflow their type, and OLED text wider than the 128-px screen.
File problems
Invisible BOMs, binary or control bytes, characters pasted from chats and web pages, and junk left after the end of the code.
Suspicious code
= where you meant ==, wait() outside a combo, a ; right after if (...), and variables or combos that are never used.
Errors and warnings
Errors will very likely stop the script compiling. Warnings compile, but are worth a look.
The rules and the list of built-in functions and constants come from the official Cronus GPC scripting guide (opens in a new tab). This checker catches the mistakes that most often stop a script compiling, but it isn't Zen Studio: Zen Studio's compiler has the final word.
