Okay, I have tested the new version on Ubuntu now and it seems to be working just fine. It features detection of Linux desktops without gnome and Macs, and opening of files for them ^^

Please tell me how it runs on OSX ;)

popen isn't supported for me it seems. How about using os.execute with output redirection, like this:

Code: Select all

local file = os.tmpname()
os.execute('uname -s > ' .. file)
local f = io.open(file)
local os = f:read('*a')
f:close()
I haven't tested it, nor did I look at the manual, but I think that's correct.

Man I find Lua's lack of functionality annoying.

Or use io.popen() instead of os.execute()

Code: Select all

local f = io.popen("pwd") -- runs command
local l = f:read("*a") -- read output of command
print(l)
f:close()

Code: Select all

function execute(cmd)
        local f = io.popen(cmd)
        local str = f:read("*a")
        return str
end

function str2tbl(str, sep)
        sep = sep or "\n"
        local t = {}
        for line in string.gmatch(str, "[^\n]+") do
                table.insert(t, line)
        end
        return t
end

table.foreach(str2tbl(execute("uname -s")), print)

io.popen works fine using a regular Lua install but says it's not supported when I run it through LÖVE, oddly enough (OSX).

It is non-portable, and it seems most love distributed lua builds don't support it.
