0.13.1 Columns Selection DSL, KDocs, Table Rendering, and Many Fixes!

[Jolanrensen]

We just released v0.13.1!

Documentation/Readme might not be up-to-date yet. However, feel free to test it in your project and let us know if something does not work as expected!

To sum up the most significant changes:

• We finally merged the new ColumnsSelection DSL (documentation will come too). This comes with KDocs everywhere, previously missing overloads, and clearer function names.
• We're continuously improving support for Kotlin Notebook by creating and improving a native table component for DataFrames, by @ermolenkodev
• (Nested) table output now looks better for notebooks on Github (for example)
• Improvements to Arrow reading (thanks, @fb64 and @Kopilov!)
• Many other fixes and version bumps, see below!

This discussion was created from the release 0.13.1 Columns Selection DSL, KDocs, Table Rendering, and Many Fixes!.

[pacher]

Was always too shy to ask, is native table component for DataFrames closed-source? Is it possible to use it in own projects without notebooks?

[Kopilov]

@pacher DataFrame library is absolutely open source and free to bu used in any projects (Apache-2.0 license)

I have made two projects with this library, both are Gradle-built backend or just CLI

[pacher]

Hey @Kopilov Thanks!
The question is not about kdf, but about the new Swing (what they call native) component rendering tables in the kotlin notebooks plugin for IDEA. As opposed to html table rendering which was used before and which is indeed part of the open source dataframe library.

[ermolenkodev]

@pacher Yes, the UI component is currently closed-source and tightly integrated with the IntelliJ IDEA Ultimate SDK.

[ermolenkodev]

Yes, indeed it is native to the IDE, not to the OS. :)
