lua documentation: Indexing of tables. Example. Perhaps the most important use of metatables is the possibility to change the indexing of tables.

Puisque vous pouvez indexer une table avec n'importe quelle valeur, vous pouvez démarrer les index d'un tableau avec n'importe quel nombre qui vous plaît. Everything is a table. Ever coded in Ruby or Python? In those, everything defaults to object and is dynamically typecast via duck typing (if it walks like a duck and talks like a duck, the compiler will treat it as a duck). In LUA, everything defaults to tables. What does that mean for me? The only data structure is a table.

Print lua table

c++,lua. The bug is in lua_next(L, -2) line, because -2 refers to stack top minus one, which happens here to be the last argument to print. For tables using numeric keys, Lua provides an ipairs function. The ipairs function will always iterate from table[1], table[2], etc. until the first nil value is found. for i = 1, #numeric_table do print(i, ".

Facebook0Tweet0Pin0 So far, we’ve learned a lot about working with data within a program, and how to include more Lua into a program, but not how to import and export data from a file. Lua has plenty of builtin features to handle this via the I/O Library. The I/O library works with both text and […]

This language is in C and designed from the start to be software that can be integrated into C and other conventional programming languages. In Lua, tables are considered as the one and only data structure that creates several types such as dictionaries and arrays. Se hela listan på tutorialspoint.com All Lua base functions (like print, pairs, next, tostring, tonumber, ) are stored in the global table. Try this in Lua interpreter: a = 'a global variable' print(_G['a'], _G.a) -- equivalent To list all the global variables, you can use this as was written earlier: for k , v in pairs(_G) do print(tostring(k).." you can copy my printTable() function for example to your Lua script and use it there. for example assume you have file named myLuaScript.lua -- create a table YourTable = {1,2,3} -- print the table using my function printTable(YourTable) and then run the script in the shell with lua myLuaScript.lua Most pure lua print table functions I've seen have a problem with deep recursion and tend to cause a stack overflow when going too deep. This print table function that I've written does not have this problem. It should also be capable of handling really large tables due to the way it handles concatenation.

This is a Lua comment local n = 8 local t = {} -- t is a Lua table -- Define a table containing the given values -- access to elements print (primeNumbers [1]) --> 2 For more details refer to the Lua website and to the numerous examples contained in the demo scenes. print(myTable[1]) -- prints the first element in the table alive = "I'm not dead yet!" print( phleep.alive ) --> I'm not dead yet! The code sample above shows the table field changing Besides the lack of print() , there are other features missing – see Differences A Lua table is expressed as a list of values separated by commas, within curly print(tab["x"]) -- read value of “x” field and print it. 5.

print_r函数可以完整的打印table，并且可以清晰的打印table中嵌套table的内容。对于调试和检查程序都有很大的好处。另外，直接使用print_r不太符合直觉，可以把函数放如table的名字空间里，如下： Lua table(表) table 是 Lua 的一种数据结构用来帮助我们创建不同的数据类型，如：数组、字典等。 Lua table 使用关联型数组，你可以用任意类型的值来作数组的索引，但这个值不能是 nil。 Se hela listan på foldit.fandom.com Lua tables are the ultimate one-stop-shop of data structures. It can be confusing that a table can behave like both kinds of containers at once, such as {1,2,3,enable=true} . So you will see reference to the array-part and the 'hash' part of a table. lua自带的print函数只能打印可转化为字符串的数据，如果打印table表的话，则会和打印函数和userdata类型数据一样，输出为内存地址的形式。工作中因项目需要，可打印 table 表的话，对bug的查修和信息的监控将会高效的多。 Lua table 使用关联型数组，你可以用任意类型的值来作数组的索引，但这个值不能是 nil。 Lua table 是不固定大小的，你可以根据自己需要进行扩容。 Lua也是通过table来解决模块（module）、包（package）和对象（Object）的。例如string.format表示使用"format"来索引table Я узнал, как переопределить Lua print() в C++ из этого поста.

tostring(j) end end Hey all! I wrote a function that will come in handy when printing tables in Lua. Normally, when you call print on a table, it is first tostring-ed into a memory address and looks something like table: 000002074CD2C070. How unhelpful! If only there was a better way… I’ve created a function, repr, that works like Python’s repr. It’s short for representation, and it returns a nice I believe that recent versions of ngx_lua have the problem that if you pass a table to ngx.print() they segfault. I say believe, because the builds I run have a lot of code that I've been hacking recently, so there may be a bug in that, but I tried back to version 2.0 of ngx_lua and it went away.

For string keys only, Lua provides an alternate syntax, where t.foo is exactly equivalent to t["foo"]. I believe that recent versions of ngx_lua have the problem that if you pass a table to ngx.print() they segfault.
