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>>

Wath's the meaning of "file:///"?? I have just used it in ReportViewer to identify a path in an expression but I really don't know the meaning of it.
Thanks
Found it!

Searching for "file:///" on the search engines does not give any usefull results :)
Thanks!
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.
I just want to know how to find/create a function to list all crontables already scheduled in NodeMCU.

Thanks.
That feature is currently not available. There's a discussion about that at https://github.com/nodemcu/nodemcu-firmware/issues/1751.

Hi there.
So, there is some issues with it.
Now, schedule string description (like 0 1 * * *) is being parsed once you call :schedule method, and stored in packed bitmask format. There is difficult thing to process it back to string.
So list of entries without something that describing them is totally unusable (correct me if I wrong).
As module initiator and maintainer I prefer to keep it simple as possible, but if we can make it better - this is good :)
I have a method for which I need to pass a record as a binary. I tried list_to_binary/1 both by passing the record itself in and converting the record to a list first then passing it in. However, I get a bagarg error with either options. Not sure what I'm missing? Can anyone help with this?
Thanks in advance!
If you need a binary, you might consider term_to_binary() and binary_to_term() functions..
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?
