Tool to convert the output of git diff to JSON for further processing.
Please note, for the most part this is an exercise of parsing simple structured text in Haskell and I do not promise support or feature-completeness.
Consider a git diff output looking as such:
diff --git a/factorial.py b/factorial.py
index abcdef1..1234567 100644
--- a/factorial.py
+++ b/factorial.py
@@ -1,6 +1,7 @@
def factorial(n):
+ # Calculate the factorial of a number recursively
if n == 0:
return 1
else:
- return n * factorial(n - 1)
+ return n * factorial(n - 1)
-num = 5
+num = 6
print(f"The factorial of {num} is {factorial(num)}")We can pipe this output to diffparser binary and jq for formatting:
git diff | diffparser | jqOutput:
