As I have learned here, we can tell git diff to ignore lines starting with a * using:
git diff -G '^[[:space:]]*[^[:space:]*]'
How do I tell git to ignore lines starting with a word, or more (for example: * Generated at), not just a character?
This file shall be ignored, it contains only trivial changes:
- * Generated at 2018-11-21
+ * Generated at 2018-11-23
This file shall NOT be ignored, it contains NOT only trivial changes:
- * Generated at 2018-11-21
+ * Generated at 2018-11-23
+ * This line is important! Although it starts with a *
Git is using POSIX regular expressions which seem not to support lookarounds. That is the reason why @Myys 3's approach does not work. A not so elegant workaround could be something like this:
git diff -G '^\s*([^\s*]|\*\s*[^\sG]|\*\sG[^e]|\*\sGe[^n]|\*\sGen[^e]|\*\sGene[^r]|\*\sGener[^a]|\*\sGenera[^t]|\*\sGenerat[^e]|\*\sGenerate[^d]).*'
This will filter out all changes starting with "* Generated".
