161. RE: parser (score: 74)

The program below reuses Lua's lexer. It "compress" Lua source code, removing comments and multiple blanks, but preserves line breaks. This particular application is not really important (we just ne

This is implemented in the version of lposix that I've posted here. Here is the relevant code: typedef void (*Selector)(lua_State *L, int i, const void *data); static int doselection(lua_State *L, i

Assuming I could buy it, does it cover toLua? I use that like, all the time. It's not in the ToC, but maybe it's hidden somewhere? Will one of you peoples buy it for me? I'll send you the money (plus

I've been writing Lua and Lua from C code about everyday for a year now and I still find PiL invaluable. Just yesterday in fact I looked up how to write an 'ipairs' like function from C using userdat

I've been reluctant to buy that because I thought it only covered the basics of Lua coding, like, not the C API... But now that you say it does, I have some questions: 1) What does it cover the most?

Sorry about that. Seems the code I posted has a mixture of styles in it. One uses printf to print to stdout, the other prints to wherever Lua's print() goes to which is different for me sometimes. Do

I would highly recommend picking up programming in Lua. It has all kind of stuff in there like this. You will learn Lua much faster! int stackDump(lua_State *L) { int i; int top = lua_gettop(L); pri

I don't think the case you describe can occur: 1) addtonewktable will call mergektable with a tree at the top of the stack that has a new ktable (due to the call to newktable). 2) mergektable will c

It behaves the way it does for efficiency. The length algorithm, as I understand it (from previous explanations on this list), does not and should not check every key-value pair in the table, as you

You still have a table.concat at every level of the stack. Try the following. I've only made it work for the case you test, so you'll need to finish it. local gen = ("a"):rep(v) ??? function encode_t

Programming would be sometimes easier if it was a possibility to break or continue any of a few nested loops. For example: a = 0 while a < 10 do a = a + 1 if a == 5 then continue end b = 0 while b <

Of course, but don't hold your breath :-) Yes. Being able to call functions directly from Lua is useful and fast. For example, for Windows programming, one can't imagine mapping all API functions to

Hi, I want to share a patch to optimize for-in loops for the pairs and ipairs case. It is inspired by LuaJITs ITERN optimization and a similar optimization in Luau. It works by checking in the OP_TFO

Actually, I can't say I know that rule. But ignorance of the law is not an excuse. In any case, I hacked a bit and got this to (seemingly) work a,nil,c = foo() nil in a `local` declaration list is go

Compile it with luac -s and compress the result. I've attached some utility code for loading Lua chunks (source or compiled, since Lua doesn't care) that have been compressed in zlib or gzip format.
