QUESTION
I have data that needs to be extracted from a file, the lines I need for the moment are name,location and host. This is example of the extract. How would I go about getting these lines into a separate file? I have the Original file and the new file i want to create as the input/output file, there are thousands of devices contained within the output file and they are all the same formatting as in my example.
...ANSWER
Answered 2021-May-28 at 08:16As what you have there is JSON, you should parse it with a JSON parser. JSON::PP is part of the standard Perl distribution. If you want something faster, you could install something else from CPAN.
Update: I included a link to JSON::PP in my answer. Did you follow that link? If you did, you would have seen the documentation for the module. That has more information about how to use the module than I could include in an answer on SO.
But it's possible that you need a little more high-level information. The documentation says this:
JSON::PP is a pure perl JSON decoder/encoder
But perhaps you don't know what that means. So here's a primer.
JSON is a text format for storing complex data structures. The format was initially used in Javascript (the acronym stands for "JavaScript Object Notation") but it is now a standard that is used across pretty much all programming languages.
You rarely want to actually deal with JSON in a program. A JSON document is just text and manipulating that would require some complex regular expressions. When dealing with JSON, the usual approach is to "decode" the JSON into a data structure inside your program. You can then manipulate the data structure however you want before (optionally) "encoding" the data structure back into JSON so you can write it to an output file (in your case, you don't need to do that as you want your output as CSV).
So there are pretty much only two things that a Perl JSON library needs to do:
- Take some JSON text and decode it into a Perl data structure
- Take a Perl data structure and encode it into JSON text
If you look at the JSON::PP documentation you'll see that it contains two functions, encode_json()
and decode_json()
which do what I describe above. There's also an OO interface, but let's not overcomplicate things too quickly.
So your program now needs to have the following steps:
- Read the JSON from the input file
- Decode the JSON into a Perl data structure
- Walk the Perl data structure to extract the items that you need
- Write the required items into your output file (for which Text::CSV will be useful
Having said all that, it really does seem to me that the jq
solution suggested by user157251 is a much better idea.
QUESTION
I would very much like to make an illustration like the one in the link:
I have trouble doing it in Python as it creates multiple linked figures which I do not want. My script is:
import plotly.graph_objects as go
ANSWER
Answered 2021-Apr-24 at 13:24Since you are using the Sankey dialog on the official site, I will edit it to show the data structure between the ABs. Simply put, the source is A, the target is B, and the rest is an iteration of that. The additional labels as shown in the link in your question are not available in plotly's sankey dialog as far as I know. You'll have to get creative with the labels. I will add a text based explanation of what I am doing.
QUESTION
Background
I have been working on creating an alluvial plot (kind of Sankey diagram) using ggplot
and the ggalluvial package to visualize frequency differences over time and their origins.
As example, I have created a simple dataset of 100 imaginary patients that are screened for COVID-19. At baseline, all patients are negative for COVID-19. After let’s say 1 week, all patients are tested again: now, 30 patients are positive, 65 are negative and 5 have an inconclusive result. Yet another week later, the 30 positive patients remain positive, 10 patients go from negative to positive, and the others are negative.

I'm trying to analyze complex survey data with Survey.

I am having trouble driving the creation of summary tables with sub-levels (two levels of stratification; nesting) via gtsummary::tbl_svysummary.
I have already created the object survey::svydesign with the following variables: Gender, Country, Result, n(weighted). I managed to create a table, however I can't create an additional stratum by Gender. I have put the tabular structure I want below.
I could even generate individual tables (nesting each country by filter) and stack them. However, there are 21 countries and I would like a more rational strategy.
Please, any suggestions...

Answered 2021-Mar-05 at 00:59Here's an example that gets you very close to the mocked-up table you provided. You can convert the output to flextable with as_flex_table()
to make it aa bit more similar.
QUESTION
When I receive mining.notify from pool (Stratum mining protocol), previous block hash not exists in blockchain.
Can someone explain this?
For example, I received this data from pool:
...ANSWER
Answered 2021-Mar-02 at 17:04I found answer. Previous block hash inside "mining.notify" is 8 x 4-Byte-string expressed as little endian.
in my case byte array: 852ab3ac_f6baeb51_e883cc88_f49ef03a_e17ed811_0009a5fb_00000000_00000000
This array is a collection of eight 4-Bytes words that, when converted to big endian, produce "00000000_00000000_0009a5fb_e17ed811_f49ef03a_e883cc88_f6baeb51_852ab3ac", which is Block 672486
