See also <http://www.lua.org/wshop06.html#Belmonte>. In any case, I think the Lua authors plan to have lua.c honor __tostring on unhandled exception objects in a future release. --John

This is backwards. The better approach would be to implement a JavaScript to Lua bytecode compiler and standard JavaScript libraries. Sneak it into browsers as a drop-in replacement for Spidermonkey

Yes, and consider that it's the complexity of SpiderMonkey which makes it intolerably slow, have a hideous C API, and be (historically) bug-ridden. --John

I mentioned this briefly in my workshop presentation on exceptions, but I encourage those interested to read the short page on exception safety for the D Programming Language [1]. It explains why nei

Looks like a bug with the Namazu search tool-- their site search has the same behavior (http://www.namazu.org/). I don't think development of Namazu is very active, but I'll try to post a report on t

See <http://lua-users.org/wiki/LuaUsersLottery> for an opportunity to lose money (and help support lua-users.org). The lua-users.org site, with a current pace of about 10 million page views per year,

I haven't had any luck contacting the two winners of the drawing-- I suspect everyone has their spam filters set too high. (What, messages with "you have won the lottery!" can't be valid?) Tim Hunter

...which could be said of any language with saner string support than C. I don't agree. For shortest average completion time of a random programming task, you will benefit from a large number of avai

391. lists with nil play nice for Lua 5.2 (score: 1)

Author: John Belmonte <john@...>

Recently I began using Lua again in a real product, my last serious use being at the time of version 4.0. From the perspective of 4.0 to 5.1, lists have gone from tolerable to bad with regard to nil

Following are further notes on this. The list implementation uses nil as an end sentinel. This value works out nicely since it is the value of a nonexistent table key, and hence the end sentinel need

I'd like to step back from the argument of whether nils belong in lists or not. Rather I'll point out some general, but related, gaps in Lua's extensibility and orthogonality-- hopefully there will b

That is a recursive argument. Lua uses convention "c" because it has 1-based indexing. The choice of index base drives how you specify ranges. No sane language or library would mix 1-based indexing w

I thought coroutines were entirely the right construct for state machines. Actually, neither goto or nested if's are readable, but fortunately these two are not the only solutions as you suggest. Sco

Software for automatic translation *to* your native language is useful. Given the knowledge of your own language, it's often easy to deduce what the computer meant despite the inevitable translation

I think this is fine if there are no dependencies, but bowing to the release managers here sets a bad precedent. Don't be surprised in the future when they want to kill 5.0 and 5.1 after newer versio

Here are my random thoughts in response to this thread. It's still the case that languages like Python and Perl are superior for completing the average random programming task in less time than Lua,
