!!!tip "`conda-deny` in one command:"
In your favorite `pixi` workspace, run:
```bash
pixi exec conda-deny check --osi
```
This will check your workspace for license compliance against the list of [OSI approved licenses](https://opensource.org/licenses).
[conda-deny](https://github.com/Quantco/conda-deny) is a CLI tool for checking software environment dependencies for license compliance.
Compliance is checked with regard to an allowlist of licenses provided by the user.
### πΏ Installation
You can install `conda-deny` using `pixi`:
```bash
pixi global install conda-deny
```
Or by downloading our pre-built binaries from the [releases page](https://github.com/quantco/conda-deny/releases).
### π― Usage


`conda-deny` can be configured in your `pixi.toml` or `pyproject.toml` (`pixi.toml` is preferred).
The tool expects a configuration in the following format:
```toml
[tool.conda-deny]
#--------------------------------------------------------
# General setup options:
#--------------------------------------------------------
license-allowlist = "https://raw.githubusercontent.com/quantco/conda-deny/main/tests/test_remote_base_configs/conda-deny-license_allowlist.toml" # or ["license_allowlist.toml", "other_license_allowlist.toml"]
platform = "linux-64" # or ["linux-64", "osx-arm64"]
environment = "default" # or ["default", "py39", "py310", "prod"]
lockfile = "environment/pixi.lock" # or ["environment1/pixi.lock", "environment2/pixi.lock"]
# lockfile also supports glob patterns:
# lockfile = "environments/**/*.lock"
#--------------------------------------------------------
# License allowlist directly in configuration file:
#--------------------------------------------------------
safe-licenses = ["MIT", "BSD-3-Clause"]
ignore-packages = [
{ package = "make", version = "0.1.0" },
]
```
After the installation, you can run `conda-deny check` in your workspace.
This checks the dependencies defined by your `pixi.lock` against your allowlist.
### π Authorized access to allowlist
If a Bearer Token is needed to access your allowlist, you can provide it using `CONDA_DENY_BEARER_TOKEN`.
An example use case would be a private repository containing your allowlist.
### Output Formats
`conda-deny` supports different output formats via the `--output` (or `-o`) flag.
Output formatting works for both, the `list` and the `check` command.
=== "CSV"
```bash
$ conda-deny list --output csv
package_name,version,license,platform,build,safe
_openmp_mutex,4.5,BSD-3-Clause,linux-aarch64,2_gnu,false
_openmp_mutex,4.5,BSD-3-Clause,linux-64,2_gnu,false
...
```
=== "JSON"
```bash
$ conda-deny list --output json-pretty

},

```
!!!tip Creating License Bundles
By running `conda-deny bundle`, `conda-deny` will create a directory containing all your dependencies' original license files.
This can come in handy when creating SBOMs or sharing compliance information with other people.
