How to filter git diff based on file extensions?

Question

Is there an option to restrict git diff to a given set of file extensions?

Answer 1

For simple file patterns, this seems to work:

$ git ls-files -zm '*.txt' | xargs --null git diff

Whitespace safe, and you can have multiple extensions too:

$ git ls-files -zm '*.h|*.c|*.cpp' | xargs --null git diff

Answer 2

Yes, if you ensure that git expands a glob rather than your shell then it will match at any level so something like this (quotes are important) should work fine.

git diff -- '*.c' '*.h'

Answer 3

To include files recursively (including current dir) this worked for me:

git diff -- '***.py'

Answer 4

Attention that params order makes difference...for example:

git diff master --name-only --relative -- "**/*.ts" "**/*.tsx" "**/*.js" "**/*.jsx" "**/*.vue"

'diff' need to be followed with 'master'
