Awareness

If Kotlin is a language you like, or are interested in, please inform your fellow members of the Kotlin community; this page can't be emptied without your and their participation.

Not implemented

These are currently not implemented in Kotlin. Please implement some if you can. If any tasks are not possible or too complex in Kotlin, they should not be on this list. To mark a task as such, add {{omit from|Kotlin}}, preserving the capitalization of the language, to that task. It will appear below under the "Not Considered" section.

Draft tasks without implementation

These tasks are drafts, meaning they largely need more work to turn them into full tasks. Perhaps you can help by trying to implement them in Kotlin (after all, one of the key requirements for a task being non-draft is multiple implementations, preferably in widely different languages) but be aware that this may be difficult because of lack of definition of the task itself.

Requiring Attention

Examples

These tasks have implementations in Kotlin, but somebody, somewhere, decided that the example implementation was faulty or in some other way requiring attention. If you're familiar with the task and language, please consider reviewing/correcting the example and removing the notice.

Y

• Yahoo! search interface

Other pages

These are other pages related to Kotlin which require attention; with your knowledge and assistance, we can improve the quality of the site's content.

---

Not Considered

These tasks are not generally counted toward "unimplemented", as somebody, somewhere, decided that Kotlin was inappropriate for these tasks, or implementations of them would be unenlightening. Feel free to try your hand at them anyway.

End of List

Again, feel free to try your hand at any of the tasks listed on this page.
