Configuration

Configuration files

ty supports persistent configuration files at both the project- and user-level.

Specifically, ty will search for a pyproject.toml or ty.toml file in the current directory, or in the nearest parent directory.

If a pyproject.toml file is found, ty will read configuration from the [tool.ty] table. For example, to ignore the index-out-of-bounds rule, add the following to a pyproject.toml:

pyproject.toml:

[tool.ty.rules]
index-out-of-bounds = "ignore"

(If there is no tool.ty table, the pyproject.toml file will be ignored, and ty will continue searching in the directory hierarchy.)

ty will also search for ty.toml files, which follow an identical structure, but omit the [tool.ty] prefix. For example:

ty.toml:

[rules]
index-out-of-bounds = "ignore"

Note

ty.toml files take precedence over pyproject.toml files, so if both ty.toml and pyproject.toml files are present in a directory, configuration will be read from ty.toml, and the [tool.ty] section in the accompanying pyproject.toml will be ignored.

ty will also discover user-level configuration at ~/.config/ty/ty.toml (or $XDG_CONFIG_HOME/ty/ty.toml) on macOS and Linux, or %APPDATA%\ty\ty.toml on Windows. User-level configuration must use the ty.toml format, rather than the pyproject.toml format, as a pyproject.toml is intended to define a Python project.

If project- and user-level configuration files are found, the settings will be merged, with project-level configuration taking precedence over the user-level configuration.

For example, if a string, number, or boolean is present in both the project- and user-level configuration tables, the project-level value will be used, and the user-level value will be ignored. If an array is present in both tables, the arrays will be merged, with the project-level settings appearing later in the merged array.

Settings provided via command line take precedence over persistent configuration.

See the configuration reference for an enumeration of the available settings.
