There is a very good discussion on using a table in a predefined variables to store the ID's of scenes and devices for the HC2 Please login or register to see this link.
If you take json string above and paste it into There are a number of websites that will 'pretify' the string make it easier to read the structure and enable you to understand how you might navigate it. Sometimes a json string can be difficult to read and understand its structure. Typically they would look something like this. Making json strings/output easier to read. assign the new value, encode it and the store it. Once it's decoded you can then read one of the values or manipulate the table In order to read back a single value you need to decode the string To save the table you need to encode it and then save it to the global variable It is easy for machines to parse and generate." "JSON (JavaScript Object Notation) is a lightweight data-interchange format. If you want to store this table in a global variable you will need to encode the table as a string. One of the most common formats to encode a table (structure) is json Please login or register to see this code. If you take the following table structure 4: table.remove (table, pos) Removes the value from the table. 3: table.maxn (table) Returns the largest numeric index. 2: table.insert (table, pos, value) Inserts a value into the table at specified position. Tables can be very confusing and frustrating to us newbie's, so take your time ncat (table, sep, i, j) Concatenates the strings in the tables based on the parameters given. Lua uses associative arrays and which can. Lua queries related to lua table insert lua insert into a table lua table.insert key and value lua add number to table set table value lua lua inserting objects into tables lua insert to table lua push table to inside table lua append array\ table insert lua copy value insert lua fastest way to add to table lua lua push to table. This is the smallest table and stores the reference to the table key - newindex(table, key, value) tkeyvalue - String concat - concat(left, right) hello. Tables are the only data structure available in Lua that helps us create different types like arrays and dictionaries. The name of the table is the variable that stores a reference to the table so it can be accessedĬreating Tables and displaying the table data The key can be any Lua value except nil and NaN. A table can store anything except nil. I would have found this very useful when I started so hopefully some users will find it useful as well.Ī table is a tree structure, consisting of field and each field has a "key" and "value" pair. Nested Tables - printing, updating, inserting, Updating tables - adding adding, inserting values
Topics covered with lots of sample code and expected outputsĬreating tables and printing (ordered, non-ordered, numerical and non numerical keys)
This tutorial has been going through a major update and expansion since the first release. Special thanks deserved to others for helping me understand many of the underlying table concepts and for also contributing a lot to this tutorial. It may be a good idea to paste some of the code in this tutorial into a test scene to understand how they work by reviewing the output
