A module for Garry's Mod that adds hooks for obtaining errors that happen on the client and server (if activated on server, it also pushes errors from clients).
luaerror.Version -- holds the luaerror module version in a string form
luaerror.VersionNum -- holds the luaerror module version in a numeric form, LuaJIT style
luaerror.EnableRuntimeDetour(boolean) -- enable/disable Lua runtime errors
luaerror.EnableCompiletimeDetour(boolean) -- enable/disable Lua compiletime errors
luaerror.EnableClientDetour(boolean) -- enable/disable Lua errors from clients (serverside only)
-- returns nil followed by an error string in case of failure to detour
Hooks:
LuaError(isruntime, fullerror, sourcefile, sourceline, errorstr, stack)
-- isruntime is a boolean saying whether this is a runtime error or not
-- fullerror is a string which is the full error
-- sourcefile is a string which is the source file of the error
-- sourceline is a number which is the source line of the error
-- errorstr is a string which is the error itself
-- stack is a table containing the Lua stack at the time of the error
ClientLuaError(player, fullerror, sourcefile, sourceline, errorstr, stack)
-- player is a Player object which indicates who errored
-- fullerror is a string which is the full error (trimmed and cleaned up)
-- sourcefile is a string which is the source file of the error (may be nil)
-- sourceline is a number which is the source line of the error (may be nil)
-- errorstr is a string which is the error itself (may be nil)
-- stack is a table containing the Lua stack at the time of the error
-- sourcefile, sourceline and errorstr may be nil because of ErrorNoHalt and friends
The only supported compilation platform for this project on Windows is Visual Studio 2017 on release mode. However, it's possible it'll work with Visual Studio 2015 and Visual Studio 2019 because of the unified runtime.
On Linux, everything should work fine as is, on release mode.
For macOS, any Xcode (using the GCC compiler) version MIGHT work as long as the Mac OSX 10.7 SDK is used, on release mode.
These restrictions are not random; they exist because of ABI compatibility reasons.
If stuff starts erroring or fails to work, be sure to check the correct line endings (\n and such) are present in the files for each OS.
This project requires garrysmod_common, a framework to facilitate the creation of compilations files (Visual Studio, make, XCode, etc). Simply set the environment variable GARRYSMOD_COMMON or the premake option --gmcommon=path to the path of your local copy of garrysmod_common.
We also use SourceSDK2013. The links to SourceSDK2013 point to my own fork of VALVe's repo and for good reason: Garry's Mod has lots of backwards incompatible changes to interfaces and it's much smaller, being perfect for automated build systems like Azure Pipelines (which is used for this project).
