Luacheck is completely unresponsive

[davisdude]

I installed Luacheck via LuaRocks and it is completely unresponsive to all commands. For instance, when I run luacheck --help, it hangs/freezes until I close it.

This is what luacheck.bat looks like:

@echo off
"C:\Program Files\lua\5.2.4\bin\lua.exe" -e "package.path=\"C:\\Users\\USERNAME\\AppData\\Roaming/luarocks/share/lua/5.2/?.lua;C:\\Users\\USERNAME\\AppData\\Roaming/luarocks/share/lua/5.2/?/init.lua;c:\\program files\\lua\\5.2.4\\/share/lua/5.2/?.lua;c:\\program files\\lua\\5.2.4\\/share/lua/5.2/?/init.lua;C:\\Program Files (x86)\\LuaRocks\\5.2/lua/?.lua;\"..package.path; package.cpath=\"C:\\Users\\USERNAME\\AppData\\Roaming/luarocks/lib/lua/5.2/?.dll;c:\\program files\\lua\\5.2.4\\/lib/lua/5.2/?.dll;\"..package.cpath" -e "local k,l,_=pcall(require,\"luarocks.loader\") _=k and l.add_context(\"luacheck\",\"0.20.0-1\")" "c:\program files\lua\5.2.4\\lib\luarocks\rocks\luacheck\0.20.0-1\bin\luacheck" %*
exit /b %ERRORLEVEL%

I'm using LuaRocks 2.4.2 with Lua 5.2.4.

What are versions of Luacheck dependencies (run luarocks show luafilesystem and luarocks show lanes)? Does it still happen if you forcefully remove them (luarocks remove --force luafilesystem and luarocks remove --force lanes)?

[davisdude]

I don't actually have lanes installed since it wasn't listed as a dependency, but here's the output for luarocks show luafilesystem:

LuaFileSystem 1.6.3-2 - File System Library for the Lua Programming Language

LuaFileSystem is a Lua library developed to complement the set of functions
related to file systems offered by the standard Lua distribution. LuaFileSystem
offers a portable way to access the underlying directory structure and file
attributes.

License:        MIT/X11
Homepage:       http://keplerproject.github.io/luafilesystem
Installed in:   c:\program files\lua\5.2.4\

Modules:
        lfs (c:\program files\lua\5.2.4\/lib/lua/5.2/lfs.dll)

Depends on:
        lua >= 5.1 (using 5.2-1)

Removing LuaFilesystem seems to do the trick... is there any way I can have both installed?

Edit: LuaCheck now works for individual files, but fails on directories

[mpeterv]

This implies that there is a problem with luafilesystem, what happens if you run lua -l lfs?

[davisdude]

lfs.dll was installed to lib\lua\5.2\ while Lua was looking for it in bin\. After moving the dll to bin\ , lua -l lfs now works correctly, but the operation of LuaCheck is still as described earlier (unresponsive)

[mpeterv]

So, lua -l lfs works, but luacheck --help hangs, is that right? But with luafilesystem uninstalled luacheck --help works. Is that correct?

[davisdude]

Not exactly. lua -l lfs works, but luacheck --help hangs. With luafilesystem uninstalled, luacheck works as expected, with the exception of directories.

[davisdude]

This is a problem with LuaFileSystem, not LuaCheck, so I'm closing
