From 797f59850201fcc267814be5c70d4730c4a67702 Mon Sep 17 00:00:00 2001 From: Stefan Klug Date: Tue, 11 Jun 2024 09:09:40 +0200 Subject: libtuning: Improve filename parsing In the tuning datasets, the files had names like 'imx335_1600l_3000k_1.dng'. That failed on the old filename parsing function. As there is no need to dictate the order of the tags, split the big regex into chunks and parse them one by one. This also makes the code easier to digest.
