Demo project to show how diKTat or KTlint rule set can fix style issues in your code.

KTlint/diKTat demo project

This is simple demo for ktlint and diktat project (a number of codestyle rules for Kotlin powered by KTlint framework) This simple demo is written on Java/Kotlin with the usage of Spring Boot and Thymeleaf and shows how a style of your code can be checked with diKTat rule set.

Many thanks for this idea and some design of the cite to YAPF demo project, we appreciate it, but we love Java more than Python (that's why Spring Boot is here instead of flask)

Usage

1. Write your Kotlin code snippets to the text block at the left.
2. At the bottom choose the mode fix or check and one codestyle ktlint or diktat. In case you have chosen check mode you won't see any changes in the code.
3. In case you would like to configure diktat - you can upload diktat configuration. Example can be found here
4. Press submit and see warnings above and fixed file in the right text block.

Current problems

This demo can use some old versions of ktlint framework and diktat rule set.
