Hello Kenta, About the issue #40 I look the implementation of

readAllWithHeader(): List<Map<String, String>>

it was initially as a sequence then converted to list. so I guess the implementation is already covered.

@Victor Harlan Lacson You are right! The solution is quite simple as you said. https://github.com/doyaaaaaken/kotlin-csv/pull/43#discussion_r429269076

version 0.9.0 released 🚀 https://github.com/doyaaaaaken/kotlin-csv/releases/tag/0.9.0

version 0.10.0 is released now. Thanks again to @Victor Harlan Lacson https://github.com/doyaaaaaken/kotlin-csv/releases/tag/0.10.0

version 0.10.1 is out 🚀 https://github.com/doyaaaaaken/kotlin-csv/releases/tag/0.10.1

Released 0.10.4 for bug fix. (0.10.2 and 0.10.3 are skipped from my mistake) Thanks for reporting bug. https://github.com/doyaaaaaken/kotlin-csv/releases/tag/0.10.4

Hello Kenta, I like to ask permission to feature(put link) kotlin-csv on my project will be posted on github soon. I dont have plan to set it as library within the projects since most of the setting is done within kotlin-csv, but rather make it work in tandem with kotlin-csv Im planning to create a project parsing csv file into a kotlin data class without any annotations, tho my prototype is already working. if it goes all is well maybe you could feature my work too. 😅

Cool 👍 Of course, you need no permission by me! I hope you make a good library!

I created this a while a go. thanks to your kotlin-csv https://github.com/blackmo18/kotlin-grass

I tried to implement node-js target on kotlin-csv writer. it works fine, but cant create a good test, since the nature of node to be asynchronous, the test is executed even the writing is not finished yet thus it fails

Hello @doyaaaaaaken I saw the notification for fo issue #21. I think I its the same as what i have published using kotlin-csv itself. Although I am intrigue for other implementation and approach you may have in mind. I would to contribute.

Thanks @Victor Harlan Lacson Exactly, kotlin-grass is near with my image. If you would implement, I’ll appreciate it. My API design image is here. Current API design is below.

fun readAll(data: String): List<List<String>>

And we should create new API like this.

fun<T> readAllWithType(data: String): List<T>

At first, we will support only for primitive types (not support java.time.*), attach @RequireOptIn annotation, and implement this method only (not implement

readAllAsSequence

).

Hey can anyone help with this: Any opinions? https://kotlinlang.slack.com/archives/C0922A726/p1601649299295100

Sorry for the late reply, and very thanks for useful feedback @Phani Mahesh

Actually that won’t work because the stream is closed outside the lambda, and reading from sequence fails.

Yes, this behavior is intended. As I said on [Principals section on README](https://github.com/doyaaaaaken/kotlin-csv#principals), file close is automatically done in this library. A file is open only inside

open

block. The workaround is here. I imagine your code is like this.

kotlin
suspend fun processRow(row: List<String>): List<String> {
    return row.map { "prefix-$it" }
}

val rows: List<List<String>> = csvReader().open("test.csv") {
    readAllAsSequence()
        .map { row -> processRow(row) } // Compile ERROR!! processRow is suspend function so cannot call inside lambda
        .toList()
}

In this example, you have some choices.

1. use blocking reader API `readAll` method
`val rows: List<List<String>> = csvReader().readAll("test.csv")`

2. enclose `processRow` method with `runBlocking`

I’ll look into it to see if it can improve. Issue: https://github.com/doyaaaaaken/kotlin-csv/issues/66

Hi! Might there be any chance I can use this wonderful library to parse somewhat broken csv? They seem to have quoted all fields with

"

, use

\

as escape character and `,`as delimiter, but have also escaped a comma inside the actual values which kotlin-csv refuses to parse... I'm eager to find what other nonsense is waiting for me...

i ended up using jackson-csv 🤷‍♀️

@thana Thanks for the question! Unfortunately, kotlin-csv cannot read broken CSV. 🙏

Hi, @doyaaaaaaken. can we support a mechanism for example invalid row, we can pipe some interface so it can listen into it without throwing an error and stop the process middle way, in this manner we can keep track what failed what.

Hello, I wanted to inform you that the ownership of the kotlin-csv project has been transferred from @doyaaaaaaken to @jsoizo (me). At the moment, only the GitHub repository ownership has changed, but please note that the package namespace and Maven Central repository will also be updated in the near future. Thank you for your continued support and understanding.
