Owner

Keep Slipstream current with Linden Lab's SLua (Luau-based server-side scripting) and make sure we're fully ready when it leaves beta.

What we have today

LL's script editor work for viewer issue #3423, inherited via upstream (commits 7f88aedbc3 add Lua as a compile target, fd82aa010c adapt to server changes, a54ac5a67f grey out Lua on unsupported regions):
- compile targets luau ("SLua") and lsl-luau in the script editor (panel_script_ed.xml, llpreviewscript.cpp ~590);
- Lua keywords / syntax highlighting (LLSyntaxLua, llscripteditor.cpp initKeywords);
- region gating (the SLua items are disabled where the region doesn't support Lua);
- external editor files saved as .luau.
Slipstream: the LSL preprocessor skips SLua scripts (the editor and the compile queue / mass recompile: llcompilequeue.cpp ~440, llpreviewscript.cpp ~746).

Tasks

Pull in LL's SLua changes since our fork. Diff LL's viewer (secondlife/viewer, develop / release branches and the SLua project branches) for anything touching Lua/Luau. For example:
- script editor / compile-target behaviour;
- the syntax/keywords source (the region LSLSyntax-style capability and its Lua equivalent, versioned keyword files);
- the require / module support UI;
- new inventory / asset handling for Lua scripts;
- the compile error / output format;
- debugger or console hooks;
- script limits / memory reporting changes for Lua (Script Info, About Land scripts, the Top Scripts estate tools).
Port what's missing. Also check Alchemy and Firestorm for their SLua handling.
End-to-end verification on SLua-enabled regions (the beta grid / SLua test regions):
- create, edit, save and compile an SLua script;
- lsl-luau (LSL compiled to the Luau VM);
- errors shown on the correct lines;
- recompile / mass recompile (Build > Scripts > Recompile / Reset in selection) with Lua targets;
- external editor round trip (.luau);
- syntax highlighting from the region's keyword file (falling back to bundled keywords);
- scripts in object contents vs inventory;
- "Running" / "Mono"-style checkboxes behave sensibly for Lua.
Our own features with SLua:
- the LSL preprocessor stays off for Lua, but consider whether a Lua-aware #include / require helper is wanted;
- Area Search script info (#425 / the bridge #428) reporting Lua script memory/time correctly;
- the debug / script error console showing Lua errors properly;
- the wiki: an SLua section in the script-editing docs (#415).
Watch LL's announcements and SLua status (beta → release): server-side changes that need viewer updates (new capabilities, new message fields, keyword file versions) should be tracked here or in follow-up tickets.

Done when

Parity with LL's current SLua viewer support (ported / verified list in this ticket).
End-to-end checks pass on an SLua region (create / compile / errors / recompile / external editor / highlighting).
Wiki covers writing SLua in Slipstream.

Keep Slipstream current with Linden Lab's **SLua** (Luau-based server-side scripting) and make sure we're fully ready when it leaves beta. ## What we have today - LL's script editor work for viewer issue #3423, inherited via upstream (commits `7f88aedbc3` add Lua as a compile target, `fd82aa010c` adapt to server changes, `a54ac5a67f` grey out Lua on unsupported regions): - **compile targets** `luau` ("SLua") and `lsl-luau` in the script editor (`panel_script_ed.xml`, `llpreviewscript.cpp` ~590); - **Lua keywords / syntax highlighting** (`LLSyntaxLua`, `llscripteditor.cpp` `initKeywords`); - **region gating** (the SLua items are disabled where the region doesn't support Lua); - external editor files saved as `.luau`. - Slipstream: the **LSL preprocessor skips SLua scripts** (the editor and the compile queue / mass recompile: `llcompilequeue.cpp` ~440, `llpreviewscript.cpp` ~746). ## Tasks 1. **Pull in LL's SLua changes since our fork.** Diff LL's viewer (`secondlife/viewer`, develop / release branches and the SLua project branches) for anything touching Lua/Luau. For example: - script editor / compile-target behaviour; - the syntax/keywords source (the region `LSLSyntax`-style capability and its Lua equivalent, versioned keyword files); - the `require` / module support UI; - new inventory / asset handling for Lua scripts; - the compile error / output format; - debugger or console hooks; - script limits / memory reporting changes for Lua (Script Info, About Land scripts, the Top Scripts estate tools).
