Support for different Lua versions about lua-language-server HOT 11 CLOSED

Yes, the next feature in plan is to support multi lua version.

from lua-language-server.

That's great news! Will that include LuaJIT? As it has a few syntactic changes that the current parser can't handle:

from lua-language-server.

LuaJIT is also in plan, but not include in next feature. I've never used LuaJIT before, so I need to study the grammar of LuaJIT first.

from lua-language-server.

That's fine, great to know you're still considering it. The grammar changes are very minor compared to regular Lua. I believe that the whole extent of the changes is mentioned here: http://luajit.org/extensions.html

from lua-language-server.

@z16 Could you please tell me the syntactic changes of LuaJIT? I didn't find them in http://luajit.org/extensions.html, for example 0ULL.

Is _VERSION == 'Lua 5.1' in LuaJIT?

from lua-language-server.

The only changes to the parser that I'm aware of are mentioned at the very bottom of this page:
http://luajit.org/ext_ffi_api.html

To quote:

Extensions to the Lua Parser

The parser for Lua source code treats numeric literals with the suffixes LL or ULL as signed or unsigned 64 bit integers. Case doesn't matter, but uppercase is recommended for readability. It handles both decimal (42LL) and hexadecimal (0x2aLL) literals.

The imaginary part of complex numbers can be specified by suffixing number literals with i or I, e.g. 12.5i. Caveat: you'll need to use 1i to get an imaginary part with the value one, since i itself still refers to a variable named i.

And yes to the other question:

Thank you!

Just wanted to say that I tried it, and it works great!

The only thing is... we currently use the LuaJIT 2.1 beta, and it supports Lua 5.3's unicode literals:

This is only for LuaJIT 2.1. Would it be possible to also add support for that version?

I think that's the only syntax difference between the two. Since it's still a beta, it's not final, but it has been in beta for a few years now, and I don't know when it will be released, so I would prefer not to wait, if possible :)

Here are some documentation pages for the 2.1 beta, if it helps:

Is there any other issue with this feature?

Not that I noticed, everything else seems good so far.

Feedback is welcome if you find any problems.
