clang-tidy

[Brett Gilio]

Hi all,

Just curious, do we have clang-tidy packaged somewhere? I have clang
installed and am not able to reference that binary in my exec path.
As far as I understand, it should be included in the default clang installation.

Best,
Brett Gilio

Hi Brett,

Clang-tidy comes from clang-extra-tools, which is not bundled in guix package.
I have my own clang packaging based on clang-7.  But I don't have time to test
upgrading LLVM on core-update.  Here is my clang package which includes clang
extra tools, anyone interested in packaging LLVM-7 for and friends for GUIX can
copy it without any constrain:

Please ignore the patches field though.
