Hi Axel, ich habe ein 'echte' Länge implementiert. Sie ist hier, magst du mal antesten und gucken, ob du es gecrasht kriegst? https://github.com/Eonblast/Lua test/len.lua und test/strlen.lua On 1/5/11 8:42 AM, Axel Kittenberger wrote: Mixing strings and offsets is something _javascript_ for example can do as well. Lua has full associates tables tough. Mixing lists with string indixes doesn't hurt the iist or # in anyway. Mixing the notion of an integer keyed hastable with a linear list does.

I cannot help noticing a flurry of recent activity on the subject of holes in tables, the definition of # etc. I note that other programming languages make a distinction between "lists" (indices a consecutive sequence of integers starting at 1 or 0 or whatever) and "hash tables", usually with strings as indices. That Lua amalgamates and extends the two seems to me to be one of its most interesting aspects. So how do others exploit this amalgamation in their Lua programming? For myself, I often have lists and then find it useful to add methods to them - something that would not be so convenient if lists and hash tables were separate notions. I tend to use the list simply as a stack, with non-nil entries, so the hole problem never arises. But maybe I am overlooking other useful ways of exploiting the amalgamation? In any case it seems to me that it would be good PR for Lua if in example code snippets those idioms which are currently unique to Lua were to be highlighted. -- Gavin Wraith (gavin@wra1th.plus.com) Home page: http://www.wra1th.plus.com/ |
