premake fails with premake5-alpha12

[derekmorr]

I'm trying to build Library-Spatial on OS X. I downloaded premake5-alpha12, but the build fails:

% ~/Downloads/premake5 vs2015

** Warning: the flags value Symbols has been deprecated and will be removed.
   Use `symbols "On"` instead
   @/Users/dvm105/landis/Library-Spatial/src/premake5.lua(14)

** Warning: the flags value OptimizeSize has been deprecated and will be removed.
   Use `optimize "Size"` instead.
   @/Users/dvm105/landis/Library-Spatial/src/premake5.lua(18)

Error: error loading module 'CSProjFile' from file './CSProjFile.lua':
    /Users/dvm105/landis/Library-Spatial/src/CSProjFile.lua:81: invalid escape sequence near '"\.'

If I manually retrieve premake5-alpha11, it works:

% ~/Downloads/premake5-alpha11 vs2015
** Warning: the flags value Symbols has been deprecated.
   Use `symbols "On"` instead

I think I've also seen this issue with Landis Core.

We should either add a note to the README, or update premake5.lua to fix the issue.

As an aside, why does the project use premake? Is there a reason the .csproj files can't be checked directly into git? They could be build using mono's xbuild or .NET Core's build tools directly w/o needing premake.

Derek,

A couple of quick notes:

• We don't have the capacity to support OSX build, I'm afraid.
• Premake is a left-over from older processes and should be retired. If you have .csproj file(s) to contribute, they would be most welcome! Once in place, I'll retire premake/lua.
• Thanks! Rob

Premake has been retired.
