Long-running write

[davidohana]

Please allow writing to csv file without having to close it.
I have a streaming scenario where I need to write each data I get to csv. Closing and reopening after each batch would be suboptimal.

Thanks

Thank you for your valuable input.

In that scenario, I guess you can write csv from streaming data like below code.
If I'm not understanding your situation correctly, please give me more details.

import com.github.doyaaaaaken.kotlincsv.dsl.csvWriter

//streaming data
val rows = sequenceOf(
    listOf("a", "b", "c"),
    listOf("d", "e", "f")
)

csvWriter().open("test.csv") {
    rows.forEach { row ->
        writeRow(row)
    }
}

Hello, in the code above, the file handle is closed at the end of the block. I get new data the I need to write to CSV every few seconds and I want to keep writing it to an open file without reopening it.

Thanks.
So, does the method openAndGetRawWriter described below solve your problem?

val writer: CsvFileWriter = csvWriter().openAndGetRawWriter("test.csv")
writer.writeRow(listOf("a", "b", "c"))
writer.writeRow(listOf("d", "e", "f"))
writer.close()

Yes it should, but I didn't see such a public method.

OK, I'll do it soon. If you'd like to implement it by yourself, feel free to tell me and send pull request.
