Re: table.sort question

[Charles Heywood <vandor2012@...>]

You can pass a function to `table.sort` along with the table to be sorted, which returns a boolean value, that will be used when sorting the table. For example:

table.sort(vAdressen, function(adr1, adr2) adr1.Name > adr2.Name end)

You can use < to sort in the other direction as well, and change Name out for City if you want to sort by city instead.

Hello,

i am new to lua. My Milestone 312 ACE, a Daisy-Player, Mp3-Player,
Audiorecorder, from Bones
 http://www.bones.ch

becomes in the next Firmware a lua-interface.

I can test the beta of that fw and so i want to program a little
adressbook.

Now i have a question to table.sort()

i have a list

local vAdressen = {}
local vAdr = {}
local vAdr.Name = ""
local vAdr.City = ""
...

I read the fields for the vAdr from a csv-file and store them  in

vAdressen[1] = vAdr
...
vAdressen[n] = vAdr

so that i have all my adress-datasets in vAdressen

Now  i want to sort the table vAdressen for name odr city or ...

If i do

print(vAdressen[1].Name]

the name of my first dataset will be printed

What st the correct syntax for the table.sort() function to sort for name
or city?

Thanks for your help.

Best regards
