# Configuration files
|
|
|
|
uv supports persistent configuration files at both the project- and user-level.
|
|
|
|
Specifically, uv will search for a `pyproject.toml` or `uv.toml` file in the current directory, or
|
|
in the nearest parent directory.
|
|
|
|
If a `pyproject.toml` file is found, uv will read configuration from the `[tool.uv.pip]` table.
|
|
For example, to set a persistent index URL, add the following to a `pyproject.toml`:
|
|
|
|
```toml
|
|
[tool.uv.pip]
|
|
index-url = "https://test.pypi.org/simple"
|
|
```
|
|
|
|
(If there is no such table, the `pyproject.toml` file will be ignored, and uv will continue searching in
|
|
the directory hierarchy.)
|
|
|
|
If a `uv.toml` file is found, uv will read from the `[pip]` table. For example:
|
|
|
|
```toml
|
|
[pip]
|
|
index-url = "https://test.pypi.org/simple"
|
|
```
|
|
|
|
uv will also discover user-level configuration at `~/.config/uv/uv.toml` (or
|
|
`$XDG_CONFIG_HOME/uv/uv.toml`) on macOS and Linux, or `%APPDATA%\uv\uv.toml` on Windows. User-level
|
|
configuration must use the `uv.toml` format, rather than the `pyproject.toml` format, as a
|
|
`pyproject.toml` is intended to define a Python _project_.
|
|
|
|
If both project- and user-level configuration are found, the settings will be merged, with the
|
|
project-level configuration taking precedence. Specifically, if a string, number, or boolean is
|
|
present in both 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 concatenated, with the
|
|
project-level settings appearing earlier in the merged array.
|
|
|
|
Settings provided via environment variables take precedence over persistent configuration, and
|
|
settings provided via the command line take precedence over both.
|
|
|
|
uv accepts a `--isolated` command-line argument which, when provided, disables the discovery of any
|
|
persistent configuration.
|
|
|
|
uv also accepts a `--config-file` command-line argument, which accepts a path to a `uv.toml` to use
|
|
as the configuration file. When provided, this file will be used in place of _any_ discovered
|
|
configuration files (e.g., user-level configuration will be ignored).
