61. writeable upvalues (score: 178)

Author: Edgar Toernig <froese@...>

Date: Wed, 12 Apr 2000 00:10:57 +0200

Hi, in a previous mail I talked about allowing assignments to upvalues. Attached is a patch that does this. It goes even further: the '%' character to introduce upvalues is removed as is the limitati

62. Re: Thoughts on optional commas (a simple way to save some commas) (score: 177)

Author: Wolfgang Pupp <wolfgang.pupp@...>

Indeed... It's probably easier to only allow omitting commas in between consecutive "Name = exp"- fields. This is much more common than '[' exp ']' = exp anyway. Lua-synax: Only one rule needs to be

Hi, folks, What is bug, what is feature ? When userdata is garbage collected if I call Lua from C ? I call it this way: --8<-- static void my_core(MyData *my) { printf("my %s: <my_core>\n",my->name);

66. Conway's Life - a coffee break puzzler (score: 168)

Author: Dave Bollinger <DBollinger@...>

Here's a tiny challenge for those interested. Attached at the bottom is a quick implementation of Conway's game of life in Lua, an algorithm which should be widely-enough recognized and well-enough d

As on any intrincate theme, and one so dear to us all, i agree on some points and disagree on others :-) agree, these are more pragmatic than clean: - weak types (automatic strings and numbers conver

I gave a lot of thought into this, and I said no, you cannot put "extreme cleanliness" as replacement in there. Lua is much to pragmatic for that. Lua's adjectives are: small and fast. And thats it,

In Lua, we favor generic and powerful constructs. Actually, a 'goto' would be almost perfect. Can we  have computed go to? http://en.wikipedia.org/wiki/Goto#Computed_GOTO (I am joking, but it would a

70. luac.c break with StkId -> StkIdRel change (score: 160)

Hi! I'd like to report that the public luac.c (with the previously-floated patch f->lineinfo=NULL applied) now fails to compile on the recently-pushed update to lua core that turned most StkId into S

Remember lambda is the ultimate goto. In Lua, instead of `goto x`, we write `return x()`. Computed goto can be written `return t[i]()`. Tony. -- f.anthony.n.finch <dot@dotat.at> http://dotat.at/ HUMB

Author: Roberto Ierusalimschy <roberto@...>

Date: Thu, 5 Jun 2008 14:01:37 -0300

We tried to clean this for 5.2. The idea is to use size_t consistently in all places, except in posrelat, that now gets a ptrdiff_t and returns a size_t. It should work for any index with an absolut

Updated patch attached 'emergency_gc-5.1.3.patch'. I fixed a few bug with doing a step collection from the allocator instead of a full collection. Also the attached 'lua_memlimit.c' program has suppo
