# bear

> A tool to generate compilation databases for `clang` tooling.
> More information: <https://github.com/rizsotto/Bear>.

- Generate `compile_commands.json` by running a build command:

`bear -- {{make}}`

- Generate compilation database with a custom output file name:

`bear --output {{path/to/compile_commands.json}} -- {{make}}`

- Append results to an existing `compile_commands.json` file:

`bear --append -- {{make}}`

- Run in verbose mode to get detailed output:

`bear --verbose -- {{make}}`

- Force `bear` to use the preload method for command interception:

`bear --force-preload -- {{make}}`
