Subject: [PATCH v5] userdiff: add builtin diff driver for kotlin language.
Date: Sun,  6 Mar 2022 16:40:31 +0530	[thread overview]
Message-ID: <20220306111031.335489-2-jaydeepjd.8914@gmail.com> (raw)
In-Reply-To: <20220306111031.335489-1-jaydeepjd.8914@gmail.com>

The xfuncname pattern finds func/class declarations
in diffs to display as a hunk header. The word_regex
pattern finds individual tokens in Kotlin code to generate
appropriate diffs.

This patch adds xfuncname regex and word_regex for Kotlin
language.
