Hi, besides that what Luigi wrote, I'd recommend the Lua users wiki. Don't take everything there as "perfect" or "the official way", as it is just a users wiki, like our wiki. http://lua-users.org/wiki/
Hello, I'd say there is no universal naming convention. For example I found local variables written with upper case (http://lua-users.org/wiki/AsciiMenu) ("local DASHES = string.rep('-', 80)") - it is not very common in programming to name local variables with upper case. But in this case - - it was probably to mark the variable as CONSTANT (as Lua doesn't have "const" keyword like C, where uppercase names are generally used for macros as constants or enums). So: - namespaces (modules) are generally named with lowercase names ('mynamespace.') (like in C? 'std::', 'boost::'), - variables are generally named with lowercase names ('_' may be used inside, so we get 'myvar' or 'my_var') - - constants with uppercase? ("local PFX = '#'"?) May be. - - global variables? One may prefer prefixing such variables somehow, so we get '_my_pfx' (or '_MyPfx' or '_myPfx')? (In C/Cpp, personally I use the 'g' prefix and camel notation, so I get 'gMyVar', opposite to all other vars with lowercase names like 'my_inner_var'.) But if a variable is to be global, it's better to encapsulate it to a namespace; thus "mark of globality" in the name gets unnecessary as we access the variable like 'mynamespace.var' (it's obvious the variable is global for that namespace). - functions? Naming like 'thisIsMyFunction()' (camel convention) is quite often, but one may prefer C-like naming ('this_is_my_function()' - so like internal variables?) or "TeX" convention ('thisismyfunction()') (natural to standard function, so we don't have 'string:g_sub()' or 'string:gSub()' but 'string:gsub()'). I'd say this to a wider discussion. You may get inspired from existing code as Patrick wrote, or e.g. to have a look into .lua scripts in ctx minimals.
