There is no decompiler. There was something experimental in the tree called "decompiler", but it doesn't really do what you'd expect. It tries to reconstruct a CFG and pseudo-SSA from the bytecode, then print it out. It didn't really work and I wouldn't use this approach again, so I deleted it.
Distributing binary plugins without making the source code available is a violation of the SourceMod license. If someone is doing this, please let me know (you can PM me or e-mail
[email protected]).
If you lost the source code, well, bad news is there's no easy answer. If it's a small plugin you can use a disassembler like
