How to verify that codechecker-run clang-tidy used my .clang-tidy config file?

[MichaelBonnet]

Hello,

I am trying to verify that my CodeChecker command indeed used the clang-tidy file I expected it to use.

My command is like so:

# Run CodeChecker analysis
CodeChecker analyze compile_commands.json --analyzers clang-tidy --file "${file_list[@]}" \
    --tidyargs="--config-file=./.clang-tidy -extra-arg=-Wno-unknown-warning-option -header-filter=.*" \
    -o ./results 

I run it in the root of my directory, with the .clang-tidy file existing at that location.

How do I verify that it indeed used those configurations?

Hello,

CodeChecker is configuring the analyzer tools through their command line interface. The reason is that in CodeChecker we want to take control over the details of analysis, e.g. which checkers are enabled, what checker config options are used, etc. If the user would be able to override some of these options, then we couldn't couldn't keep the analysis statistics up-to-date. For example, we would like to keep track of the enabled checkers, so we can set the "detection status" of reports.
For these reasons, CodeChecker overrides the .clang-tidy config file.

Side note: There is a hidden option to disable this "overriding" behavior, but we don't really support the consequences of its usage:

CodeChecker analyze compile_commands.json --analyzer-config clang-tidy:take-config-from-directory=true -o reports
