| i'm trying to capture this kind of information
ABC 123,456 (100%) or ABC 1,234,567 (100%), ABC 12 (100%)
My trigger is
ABC(.*)\(.*
here is the problem, 1% = 123 456, I have a missing "," sign here.
when i try to assign this value to a variable, it will equal to 123.
the value which i'm looking for is either "123,456" or "123456"
btw, string.len(%1) = 3
print(%1) = 123 456

| Your problem here is partly that you haven't quoted %1.
This is being fed to Lua as:
Thus, it is printing two numbers.
For a start, you need to quote it, like this:
However now your problem is you have 2 numbers inside a string. A simple "gsub" to replace commas by nothing will convert it to a single number (inside a string):
num = string.gsub ("%1", ",", "")
print (num) --> 123456
Finally, to do arithmetic on it you should probably do "tonumber" on it, to make sure it is being considered as a number:
num = tonumber (string.gsub ("%1", ",", ""))
print (num) --> 123456

| finally, I figured out I should call script function rather than setvariable under trigger...
it's so inconvenience.
and any idea to trim out the "," sign? | | Top |
