Get lines of code by file extension for a particular author?

[sffc]

Thanks for building this tool!

I have a repo, and I want to know how many lines of Rust code I've contributed to it. Is that something this tool can tell me?

If I run git fame -t, I get

Total ._None_ext: 15309
Total .bat: 41
...
Total .rs: 81316
...
Total commits: 1006
Total ctimes: 29296
Total files: 3871
Total loc: 510071
| Author                  |   loc |   coms |   fils |  distribution   |
|:------------------------|------:|-------:|-------:|:----------------|
| Elango                  | 90506 |     65 |    505 | 17.7/ 6.5/13.0  |
| Manish Goregaokar       | 84052 |    163 |    695 | 16.5/16.2/18.0  |
| Ting-Yu Lin             | 62542 |     18 |     54 | 12.3/ 1.8/ 1.4  |
| Erik Nordin             | 56941 |     21 |    265 | 11.2/ 2.1/ 6.8  |
| Shane F. Carr           | 48403 |    347 |    613 | 9.5/34.5/15.8   |
...

The list at the top tells me contributions by language, and the table at the bottom tells me contributions by user. I want contributions by language by user. Alternatively, I would be okay invoking a command such as

$ git fame -e "me@example.com" -t

which would get analysis only for commits with that email address.

git fame --incl '\.rs$'

closing for now - happy to reopen if you want.

Thanks for this software, seems like just what I was looking for.

From the README:

Extra care should be taken when using ins and/or del for --loc since all historical files (including those no longer surviving) are counted. In such cases, --excl may need to be significantly extended.

I'm not proficient with regex, could you elaborate on what you mean by "significantly extended"? Say I added to your example above

git fame --incl '\.rs$' --loc=ins

Adding --loc=ins without updating --incl seems to remove the effect of the latter option. Is this expected behaviour?
