How to use regular expressions while searching in Papertrail app?

I want to search using a regular expression in the search bar of Papertrailapp.
When I try some thing like this
randomText \(\d\d\d
Expected result : randomText (223
Actual Result : No search found.
Any guidance on this will be appreciated. Thanks.
Unfortunately, it is not possible to use Regex directly within log search.
See the search documentation here.
However, you can use regex when creating re-usable log filters which, depending on your usage, may be what you're looking for. See this documentation.

Anyone know how to disable polymer iron-autogrow-textarea input?

Can't find any info on this.
Simply trying to use 'disabled' on my iron-autogrow-textarea with no avail. Doesn't work anyway i try it, javascript or directly on element. Documentation also doesn't seem to give any insight.
Anyone have any info? Am i missing something simple?
<iron-autogrow-textarea disabled style="border:none; width: 80%;" bind-value="{{bookingDetails}}"></iron-autogrow-textarea>
Thanks everyone,
Ryann.

this.$.job_details.querySelector('textarea').disabled = true;

inet_addr functionality in erlang

As the question says, is there any function or module that performs the functionality of inet_addr ?
Results from google isnt suggesting any direct way or am i missing something ?
Thanks.
You can use inet_parse:address, and then convert the resuting list to binary. e.g.
16> list_to_binary(tuple_to_list(element(2,inet_parse:address("192.168.42.2")))).
<<192,168,42,2>>

Check whether a variable is an Array

I want to find out whether a variable is an array or not
if (params.writtenLines == ???)
Much appreciated.
More importantly, why do you want to check whether it's an array? If you know the parameter might be a single string or a list, you can now use:
def lines = params.list("writtenLines")
That came with Grails 1.2.
This functionality is already available in pure Java and can therefore be used in Groovy, too:
if (params.writtenLines.class.isArray())
I realize this is a bit late, but what about this:
List.isCase(params.writtenLines)
Wouldn't it be a correct solution, too?
