Clang-tidy Qt Creator Integration

Clang Frontend
#1

Hi all,

For checking some code according some custom code conventions, I cloned the llvm repository and wrote two checks for clang-tidy. Using the clang-tidy executable I already know that my checks behave as expected.

Until now I integrated my custom clang-tidy executable in Qt Creator by using it as an external tool and passing it some options accordingly. This also works.

Now I know, that the original clang-tidy/clazy is integrated in the Qt Creator. In the documentation on Extra Clang Tools 10 I found a page named „Clang-tidy IDE/Editor Integrations“. Qt Creator is here marked as being to able to use a custom clang-tidy binary and I would like to use that somehow. Can I find somewhere any more information about this or has someone already achieved replacing the Qt Creator’s clang and can give me a hint on how to do so? So far I tried to statically link clang-tidy into the clang executable and placed it in the Qt Creator’s clang folder (along some libs), but this is not giving me any results yet.

I would be happy if you could tell me if I’m on the right track or if there is something else I should do or try.

Thanks and greetings,

Mia

Hi all,

For checking some code according some custom code conventions, I cloned
the llvm repository and wrote two checks for clang-tidy. Using the
clang-tidy executable I already know that my checks behave as expected.

Until now I integrated my custom clang-tidy executable in Qt Creator by
using it as an external tool and passing it some options accordingly.
This also works.

Now I know, that the original clang-tidy/clazy is integrated in the Qt
Creator. In the documentation on Extra Clang Tools 10 I found a page
named „Clang-tidy IDE/Editor Integrations“. Qt Creator is here marked as
being to able to use a custom clang-tidy binary and I would like to use
that somehow.

I realize that "Custom clang-tidy binary" in that table is ambiguous:

  1. The IDE ships a custom/modified binary
     => Running other checks than provided by that binary might be hard
  2. The IDE allows using YOUR custom/modified binary
     => Pointing the IDE to another/YOUR clang-tidy binary with custom
checks should work

So what's the intention of that column? I'll correct that for Qt Creator
if necessary.

Currently, Qt Creator falls into category 1 but I'm working on this just
now so eventually it will fall into category 2.

Can I find somewhere any more information about this or
has someone already achieved replacing the Qt Creator’s clang and can
give me a hint on how to do so? So far I tried to statically link
clang-tidy into the clang executable and placed it in the Qt Creator’s
clang folder (along some libs), but this is not giving me any results yet.

What's the error message?
How do you invoke your clang-tidy binary?
Do you use the ClangTools plugin?

For the ClangTools plugin

   QT_LOGGING_RULES=qtc.clangtools.runner=true

will produce debugging output for the invocation (set it as run time env).

The way we link tidy into the clang binary is this:

I would be happy if you could tell me if I’m on the right track or if
there is something else I should do or try.

Thanks and greetings,
