# Use compilation databases

The JSON compilation database format specifies how to replay single builds independently of the build system.

A compilation database is basically a list of files and the compiler flags that are used to compile the files. The database is used to feed the code model with the necessary information for correctly parsing the code when you open a file for editing.

To open a compilation database as a project, go to File > Open File or Project and select a compilation database JSON file.

To generate a compilation database from the information that the code model has, select Build > Run Generator > Compilation Database.

You can add files, such as non-C files, to the project in compile_database.json.files.

You can use the experimental Compilation Database Project Manager to open the files in a compilation database with access to all the editing features of the Clang code model.

Note: Enable the Compilation Database Project Manager plugin to use it.

To switch between header and source files, select Tools > C++ > Switch Header/Source.

You can specify custom build steps and run settings for compilation database projects in the Projects mode.
