I'm more interested in running such tools locally, so whenever I fix an
error/warning from such a tool, I can do have these steps:

1) run the tool -> see the result

2) attempt to fix it

3) run the tool again -> see the result disappearing

If the tool is not running locally, 2) will be a blind fix, which is not
ideal.

E.g. IWYU has a wrapper in core.git, so you can run:

bin/find-unneeded-includes path/to/test.cxx

and it'll show you the IWYU result for that .cxx file.

It is possible that such a wrapper for cppcheck would be also useful,
and would require less maintenance that a full service.

The other problem with cppcheck is that it doesn't build on an existing
c++ parser from a compiler (not based on e.g. gcc or clang), so its
signal/noise ratio is lower than e.g. coverity or clang-tidy. This is of
course not your fault, but it explains if the interest is lower than
what you expect.

Regards,

Miklos
