If you just want to edit the shell stream, I would recommend sd, it uses the same concept, but its more for in stream edits. sad was inspired by my initial usage of sd. ripgrep with --replace also works. Take note however, rg will exit 1, it it finds no matches.

QUESTION
Good day everyone, I am currently struggling with writing mysql query which should make chat group from messages. App which I am making is taking data from other service, so it's not up to me to also manage chat groups, I need take this info from messages themselves.
My table of messages looks like this:
id sendAddr receiveAddr lastMessage text read 1 Ccbbd6uUZF2GD5wE5LEfjGPA3YWPjoLC6P CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF 2021-06-02 12:57:39 test3 0 5 Ccbbd6uUZF2GD5wE5LEfjGPA3YWPjoLC6P CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF 2021-06-02 13:00:44 test3 0 7 CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF Ccbbd6uUZF2GD5wE5LEfjGPA3YWPjoLC6P 2021-06-10 23:13:59 testVPS 0 8 CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF CYfMNQ62u1qwhCBqXzcmeJ8D9j4Yc1Pwef 2021-06-10 20:03:59 neco 0 9 CYfMNQ62u1qwhCBqXzcmeJ8D9j4Yc1Pwef CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF 2021-06-10 21:03:59 test 0My only input data which I sent from my mobile app is receiveAddr so I need to add this to group anything which containes address in either sentAddr or receiveAddr, here is representation of what I want to achieve
It needs to have latest text counted amount of 0 in read column and lastMessage which is time of last message
I came up with something which sort of works if the user of the mobile app would be just receiving messages, which would be this:
SELECT sentAddr, COUNT(IF(campus.messages.read = 0, 1, NULL)) as unread, max(receiveTime) as lastMessage, max(text) as text FROM campus.messages WHERE (SELECT max(receiveTime) FROM campus.messages) AND receiveAddr = 'CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF' GROUP BY sentAddr, receiveAddr
But sadly that does not get me a text from the latest message and not even taking into account that if the same user send some message, it shows as different group, which is not really helpful. I also came up with something which groups sendAddr and receiveAddr into one group no matter if it's on sending or receiving side:
GROUP BY CONCAT(LEAST(receiveAddr,sentAddr),' ', GREATEST(receiveAddr, sentAddr))
However in that case I can't with this added to upper query, it does not retrieve latest text, which is useless. So is there any chance of doing this with one query, no matter how long and convoluted it would be? And just to remind, only input data is user's address, which can be either sending or receiving address from the table. So is there any solution to this?
Version of the mysql database is 8.0.25

QUESTION
I have put example dataset (df), expected output (df2) and my code so far below. I have a df where some rows in column i2 contain a list - in the json format, which need exploding and reinserting back into the df, from the row in which they were extracted. But the need to be inputted into a different column (i1). i need to extract a unique identifier (the 'id_2' value) from the string and insert that into the id_2 column.
in my code so far i am parsing the json-like data with pd.normalize, and then inserting the original string from the column i1 onto the top of the extracted strings (it should be much more clear if you take a look below) and then reinsert them based on the index. But I have to specify the index, which is not good. I would like it to be less dependent on manual input of indices in case it changes in the future with more of these nested cells or somehow the index changes.
Any suggestions are very welcome, thanks so much

ANSWER
Answered 2021-Jun-10 at 07:38You step is doing too much. I would beak things down to two steps:
- Step 1: extracts the file information header and puts it in the job execution context
- Step 2: reads the file information header from the execution context and uses it in whatever step-scoped bean needed for that step (for example the stax callback in your case)
