| I am having problems to be able to do a trigger that orders me by categories an information that throws a command to me.
This is an example of what appears in a single line:
Level of knowledge 90% Level of domain High Chakra 200
Healing ability Gifted Reach 5
Inheritance 50
In this example, the first line has 3 components, the second line 2 components and the third 1 component. The order of the 3 lines is random.
I would like to use a trigger to sort these lines.
for example:
Line 1:
Level of knowledge 90%
Level of domain High
chakra 200
Line 2:
Healing ability Gifted
reach 5
Line 3:
Inheritance 50
I've tried to fix it with this:
Reg Exp:
[\s](.+?)[\s](\d+)\%[\s](.+)[\s](\d+)[ ](\d+)[\s](.+)[\s](\d+)[\s]
With this line only shows me the data of the first line that contains 3 parts, but if there are only 2 parts does not show anything and if it is only 1 part also does not show the data.
Any idea how to fix it? | Top |

| Can you please post the actual trigger?

I'm a bit confused about your regexp. A "set" is something in brackets, like [abc] which would match "a" or "b" or "c".
When you have this:
That is only going to match a space, so the brackets aren't required. Plus it only matches one space, and in your example you have multiple spaces. To match one or more spaces you want:

| I made some changes after reading your suggestion in the change to \s+
The actual code:
<trigger
enabled="y"
expand_variables="y"
group="Books"
keep_evaluating="y"
match="\s+(.*)\s+(\d+)\%\s+(.*)\s+(\d+)\%\s+(.*)\s+(\d+)\%\s+$"
omit_from_log="y"
omit_from_output="y"
regexp="y"
send_to="2"
sequence="100"
>
<send>%1 %2
%3 %2
%5 %6
</send>
</trigger>
Works fine when there are 3 elements in the line as in line 1 of the example. If it is the second line or the third, it does not work.
Use the following line to format the text.
As I said before, it works perfectly if there are 3 elements in the line, but if there are only 2 or 1 element does not work.
ColourNote ("white", "", string.format ("%%-25s %i%s", Trim ("%1"), %2,"%"))
The result:
Level of knowledge 90%
Level of domain High
chakra 200
with 2 elements:
Healing ability Gifted Reach 5

| You can make part of the regexp optional. eg.
^(part one)(\s+part two)?(\s+part three)?$
This has to match "part one" but also matches "part one part two" and also "part one part two part three".

Part 1: \s+(.*)\s+(\d+)\%
Part 2: \s+(.*)\s+(\d+)\%
Part 3: \s+(.*)\s+(\d+)\%\s+$
^((.*)\s+(\d+)\%)(\s+(.*)\s+(\d+)\%)?(\s+(.*)\s+(\d+)\%)?\s+$
But with this regexp not working | Top |

Part 2: \s+(.*)\s+(\d+)\%
"Level of domain High" doesn't have a % symbol in it. |
