git diff --color | python ./script.py "^[+-]import" to not show blocks with only lines changed that are import statements

imagine you have a diff output:

diff --git a/file.txt b/file.txt
index 0b669b6..54652ef 100644
--- a/file.txt
+++ b/file.txt
@@ -1,3 +1,4 @@

@@ -7,4 +8,5 @@

-10
\ No newline at end of file
+10
+bar
\ No newline at end of file

but you want to ignore all import statements line changes git diff --color | python ./script.py "^[+-]import" gives you following output:

diff --git a/file.txt b/file.txt
index 0b669b6..54652ef 100644
--- a/file.txt
+++ b/file.txt

+bar

More detailed:

if all line changes in a block (@@) match the pattern, the block is excluded from diff output
if all blocks in a file are excluded, the entire file is excluded from diff output

tip: create an alias alias gde='python ~/git-diff-exclude/script.py' (make it permanent by putting it in ~/.bash_profile) so you can call git diff --color | gde "^[+-]import"

useful patterns:

"^[+-]\s*$" empty lines
"^[+-]\s*}else$", "^[+-]\s*}$", "^[+-]\s*else$" for else { <-> else+ newline + {
