## Description
`pip-licenses` is a CLI tool for checking the software license of installed Python packages with pip.
Implemented with the idea inspired by `composer licenses` command in Composer (a.k.a PHP package management tool).
https://getcomposer.org/doc/03-cli.md#licenses
## Installation
Install it via PyPI using `pip` command.
```bash
# Install or Upgrade to newest available version
$ pip install -U pip-licenses
# If upgrading from pip-licenses 3.x, remove PTable
$ pip uninstall -y PTable
```
**Note for Python 3.7 users:** pip-licenses 4.x discontinued support earlier than the Python 3.7 EOL schedule. If you want to use it with Python 3.7, install pip-licenses 3.x.
```bash
# Using old version for the Python 3.7 environment
$ pip install 'pip-licenses<4.0'
```
**Note:** If you are still using Python 2.7, install version less than 2.0. No new features will be provided for version 1.x.
```bash
$ pip install 'pip-licenses<2.0'
```
## Usage
Execute the command with your venv (or virtualenv) environment.
```bash
# Install packages in your venv environment
(venv) $ pip install Django pip-licenses
# Check the licenses with your venv environment
(venv) $ pip-licenses
Name Version License
Django 2.0.2 BSD
pytz 2017.3 MIT
```
## Command-Line Options
### Common options
#### Option: python
By default, this tools finds the packages from the environment pip-licenses is launched from, by searching in current python's `sys.path` folders. In the case you want to search for packages in an other environment (e.g. if you want to run pip-licenses from its own isolated environment), you can specify a path to a python executable. The packages will be searched for in the given python's `sys.path`, free of pip-licenses dependencies.
```bash
(venv) $ pip-licenses --with-system | grep pip
pip 22.3.1 MIT License
pip-licenses 4.1.0 MIT License
```
```bash
(venv) $ pip-licenses --python=</path/to/other/env>/bin/python --with-system | grep pip
pip 23.0.1 MIT License
```
#### Option: from
By default, this tool finds the license from [Trove Classifiers](https://pypi.org/classifiers/) or package Metadata. Some Python packages declare their license only in Trove Classifiers.
(See also): [Set license to MIT in setup.py by alisianoi ・ Pull Request #1058 ・ pypa/setuptools](https://github.com/pypa/setuptools/pull/1058), [PEP 314\#License](https://www.python.org/dev/peps/pep-0314/#license)
For example, even if you check with the `pip show` command, the license is displayed as `UNKNOWN`.
```bash
(venv) $ pip show setuptools
Name: setuptools
Version: 38.5.0
Summary: Easily download, build, install, upgrade, and uninstall Python packages
Home-page: https://github.com/pypa/setuptools
Author: Python Packaging Authority
Author-email: distutils-sig@python.org
License: UNKNOWN
```
The mixed mode (`--from=mixed`) of this tool works well and looks for licenses.
```bash
(venv) $ pip-licenses --from=mixed --with-system | grep setuptools
setuptools 38.5.0 MIT License
```
In mixed mode, it first tries to look for licenses in the Trove Classifiers. When not found in the Trove Classifiers, the license declared in Metadata is displayed.
If you want to look only in metadata, use `--from=meta`. If you want to look only in Trove Classifiers, use `--from=classifier`.
To list license information from both metadata and classifier, use `--from=all`.
**Note:** If neither can find license information, please check with the `with-authors` and `with-urls` options and contact the software author.
* The `m` keyword is prepared as alias of `meta`.
* The `c` keyword is prepared as alias of `classifier`.
* The `mix` keyword is prepared as alias of `mixed`.
* Default behavior in this tool
#### Option: order
By default, it is ordered by package name.
If you give arguments to the `--order` option, you can output in other sorted order.
```bash
(venv) $ pip-licenses --order=license
```
#### Option: format
By default, it is output to the `plain` format.
##### Markdown
When executed with the `--format=markdown` option, you can output list in markdown format. The `m` `md` keyword is prepared as alias of `markdown`.
```bash
(venv) $ pip-licenses --format=markdown
| Name | Version | License |
|--------|---------|---------|
| Django | 2.0.2 | BSD |
| pytz | 2017.3 | MIT |
```
When inserted in a markdown document, it is rendered as follows:
| Name | Version | License |
|--------|---------|---------|
| Django | 2.0.2 | BSD |
| pytz | 2017.3 | MIT |
##### reST
When executed with the `--format=rst` option, you can output list in "[Grid tables](http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#grid-tables)" of reStructuredText format. The `r` `rest` keyword is prepared as alias of `rst`.
```bash
(venv) $ pip-licenses --format=rst
+--------+---------+---------+
| Name | Version | License |
+--------+---------+---------+
| Django | 2.0.2 | BSD |
+--------+---------+---------+
| pytz | 2017.3 | MIT |
+--------+---------+---------+
```
##### Confluence
When executed with the `--format=confluence` option, you can output list in [Confluence (or JIRA) Wiki markup](https://confluence.atlassian.com/doc/confluence-wiki-markup-251003035.html#ConfluenceWikiMarkup-Tables) format. The `c` keyword is prepared as alias of `confluence`.
```bash
(venv) $ pip-licenses --format=confluence
| Name | Version | License |
| Django | 2.0.2 | BSD |
| pytz | 2017.3 | MIT |
```
##### HTML
When executed with the `--format=html` option, you can output list in HTML table format. The `h` keyword is prepared as alias of `html`.
```bash
(venv) $ pip-licenses --format=html
<table>
<tr>
<th>Name</th>
<th>Version</th>
<th>License</th>
</tr>
<tr>
<td>Django</td>
<td>2.0.2</td>
<td>BSD</td>
</tr>
<tr>
<td>pytz</td>
<td>2017.3</td>
<td>MIT</td>
</tr>
</table>
```
##### JSON
When executed with the `--format=json` option, you can output list in JSON format easily allowing post-processing. The `j` keyword is prepared as alias of `json`.
```json
[
{
"Author": "Django Software Foundation",
"License": "BSD",
"Name": "Django",
"URL": "https://www.djangoproject.com/",
"Version": "2.0.2"
},
{
"Author": "Stuart Bishop",
"License": "MIT",
"Name": "pytz",
"URL": "http://pythonhosted.org/pytz",
"Version": "2017.3"
}
]
```
##### JSON LicenseFinder
When executed with the `--format=json-license-finder` option, you can output list in JSON format that is identical to [LicenseFinder](https://github.com/pivotal/LicenseFinder). The `jlf` keyword is prepared as alias of `jlf`.
This makes pip-licenses a drop-in replacement for LicenseFinder.
```json
[
{
"licenses": ["BSD"],
"name": "Django",
"version": "2.0.2"
},
{
"licenses": ["MIT"],
"name": "pytz",
"version": "2017.3"
}
]
```
##### CSV
When executed with the `--format=csv` option, you can output list in quoted CSV format. Useful when you want to copy/paste the output to an Excel sheet.
```bash
(venv) $ pip-licenses --format=csv
"Name","Version","License"
"Django","2.0.2","BSD"
"pytz","2017.3","MIT"
```
##### Plain Vertical
When executed with the `--format=plain-vertical` option, you can output a simple plain vertical output that is similar to Angular CLI's
[--extractLicenses flag](https://angular.io/cli/build#options). This format minimizes rightward drift.
```bash
(venv) $ pip-licenses --format=plain-vertical --with-license-file --no-license-path

OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE
SOFTWARE.
```
#### Option: summary
When executed with the `--summary` option, you can output a summary of each license.
```bash
(venv) $ pip-licenses --summary --from=classifier --with-system
Count License
2 BSD License
4 MIT License
```
**Note:** When using this option, only `--order=count` or `--order=license` has an effect for the `--order` option. And using `--with-authors` and `--with-urls` will be ignored.
#### Option: output\-file
When executed with the `--output-file` option, write the result to the path specified by the argument.
```
(venv) $ pip-licenses --format=rst --output-file=/tmp/output.rst
created path: /tmp/output.rst
```
#### Option: ignore-packages
When executed with the `--ignore-packages` option, ignore the package specified by argument from list output.
```bash
(venv) $ pip-licenses --ignore-packages django
Name Version License
pytz 2017.3 MIT
```
Package names of arguments can be separated by spaces.
```bash
(venv) $ pip-licenses --with-system --ignore-packages django pip pip-licenses
Name Version License
prettytable 3.5.0 BSD License
pytz 2017.3 MIT
setuptools 38.5.0 UNKNOWN
wcwidth 0.2.5 MIT License
```
Packages can also be specified with a version, only ignoring that specific version.
```bash
(venv) $ pip-licenses --with-system --ignore-packages django pytz:2017.3
Name Version License
prettytable 3.5.0 BSD License
setuptools 38.5.0 UNKNOWN
wcwidth 0.2.5 MIT License
```
#### Option: packages
When executed with the `packages` option, look at the package specified by argument from list output.
```bash
(venv) $ pip-licenses --packages django
Name Version License
Django 2.0.2 BSD
```
Package names of arguments can be separated by spaces.
```bash
(venv) $ pip-licenses --with-system --packages prettytable pytz
Name Version License
prettytable 3.5.0 BSD License
pytz 2017.3 MIT
```
### Format options
#### Option: with-system
By default, system packages such as `pip` and `setuptools` are ignored.
And `pip-licenses` and the implicit dependency `prettytable` and `wcwidth` will also be ignored.
If you want to output all including system package, use the `--with-system` option.
```bash
(venv) $ pip-licenses --with-system
Name Version License
Django 2.0.2 BSD
pip 9.0.1 MIT
pip-licenses 1.0.0 MIT License
prettytable 3.5.0 BSD License
pytz 2017.3 MIT
setuptools 38.5.0 UNKNOWN
wcwidth 0.2.5 MIT License
```
#### Option: with-authors
When executed with the `--with-authors` option, output with author of the package.
```bash
(venv) $ pip-licenses --with-authors
Name Version License Author
Django 2.0.2 BSD Django Software Foundation
pytz 2017.3 MIT Stuart Bishop
```
#### Option: with-maintainers
When executed with the `--with-maintainers` option, output with maintainer of the package.
**Note:** This option is available for users who want information about the maintainer as well as the author. See [#144](https://github.com/raimon49/pip-licenses/issues/144)
#### Option: with-urls
For packages without Metadata, the license is output as `UNKNOWN`. To get more package information, use the `--with-urls` option.
```bash
(venv) $ pip-licenses --with-urls
Name Version License URL
Django 2.0.2 BSD https://www.djangoproject.com/
pytz 2017.3 MIT http://pythonhosted.org/pytz
```
#### Option: with-description
When executed with the `--with-description` option, output with short description of the package.
```bash
(venv) $ pip-licenses --with-description
Name Version License Description
Django 2.0.2 BSD A high-level Python Web framework that encourages rapid development and clean, pragmatic design.
pytz 2017.3 MIT World timezone definitions, modern and historical
```
#### Option: no-version
When executed with the `--no-version` option, output without the version number.
```bash
(venv) $ pip-licenses --no-version
Name License
Django BSD
pytz MIT
```
#### Option: with-license-file
When executed with the `--with-license-file` option, output the location of the package's license file on disk and the full contents of that file. Due to the length of these fields, this option is best paired with `--format=json`.
If you also want to output the file `NOTICE` distributed under Apache License etc., specify the `--with-notice-file` option additionally.
**Note:** If you want to keep the license file path secret, specify `--no-license-path` option together.
#### Option: filter\-strings
Some package data contains Unicode characters which might cause problems for certain output formats (in particular ReST tables). If this filter is enabled, all characters which cannot be encoded with a given code page (see `--filter-code-page`) will be removed from any input strings (e.g. package name, description).
#### Option: filter\-code\-page
If the input strings are filtered (see `--filter-strings`), you can specify the applied code page (default `latin-1`). A list of all available code pages can be found [codecs module document](https://docs.python.org/3/library/codecs.html#standard-encodings).
### Verify options
#### Option: fail\-on
Fail (exit with code 1) on the first occurrence of the licenses of the semicolon-separated list. The license name
matching is case-insensitive.
If `--from=all`, the option will apply to the metadata license field.
```bash
(venv) $ pip-licenses --fail-on="MIT License;BSD License"
```
**Note:** Packages with multiple licenses will fail if at least one license is included in the fail-on list. For example:
```
# keyring library has 2 licenses
$ pip-licenses --package keyring
Name Version License
keyring 23.0.1 MIT License; Python Software Foundation License
# If just "Python Software Foundation License" is specified, it will fail.
$ pip-licenses --package keyring --fail-on="Python Software Foundation License;"
$ echo $?
1
# Matching is case-insensitive. Following check will fail:
$ pip-licenses --fail-on="mit license"
```
#### Option: allow\-only
Fail (exit with code 1) if none of the package licenses are in the semicolon-separated list. The license name
matching is case-insensitive.
If `--from=all`, the option will apply to the metadata license field.
```bash
(venv) $ pip-licenses --allow-only="MIT License;BSD License"
```
**Note:** Packages with multiple licenses will only be allowed if at least one license is included in the allow-only list. For example:
```
# keyring library has 2 licenses
$ pip-licenses --package keyring
Name Version License
keyring 23.0.1 MIT License; Python Software Foundation License
# One or both licenses must be specified (order and case does not matter). Following checks will pass:
$ pip-licenses --package keyring --allow-only="MIT License"
$ pip-licenses --package keyring --allow-only="mit License"
$ pip-licenses --package keyring --allow-only="BSD License;MIT License"
$ pip-licenses --package keyring --allow-only="Python Software Foundation License"
$ pip-licenses --package keyring --allow-only="Python Software Foundation License;MIT License"
# If none of the license in the allow list match, the check will fail.
$ pip-licenses --package keyring --allow-only="BSD License"
$ echo $?
1
```
#### Option: partial\-match
If set, enables partial (substring) matching for `--fail-on` or `--allow-only`. Default is unset (False).
Usage:
```bash
(venv) $ pip-licenses --partial-match --allow-only="MIT License;BSD License"
(venv) $ pip-licenses --partial-match --fail-on="MIT License;BSD License"
```
**Note:** Semantics are the same as with `--fail-on` or `--allow-only`. This only enables substring matching.
```
# keyring library has 2 licenses
$ pip-licenses --package keyring
Name Version License
keyring 23.0.1 MIT License; Python Software Foundation License
# One or both licenses must be specified (order and case does not matter). Following checks will pass:
$ pip-licenses --package keyring --allow-only="MIT License"
$ pip-licenses --package keyring --allow-only="mit License"
$ pip-licenses --package keyring --allow-only="BSD License;MIT License"
$ pip-licenses --package keyring --allow-only="Python Software Foundation License"
$ pip-licenses --package keyring --allow-only="Python Software Foundation License;MIT License"
# These won't pass, as they're not a full match against one of the licenses
$ pip-licenses --package keyring --allow-only="MIT"
$ echo $?
1
$ pip-licenses --package keyring --allow-only="mit"
$ echo $?
1
# with --partial-match, they pass
$ pip-licenses --package keyring --partial-match --allow-only="MIT"
$ echo $?
0
$ pip-licenses --package keyring --partial-match --allow-only="mit"
$ echo $?
0
```
### pyproject.toml support
All command-line options for `pip-licenses` can be configured using the `pyproject.toml` file under the `[tool.pip-licenses]` section.
The `pyproject.toml` file is searched in the directory where the `pip-licenses` script is executed.
Command-line options specified during execution will override the corresponding options in `pyproject.toml`.
Example `pyproject.toml` configuration:
```toml
[tool.pip-licences]
from = "classifier"
ignore-packages = [
"scipy"
]
fail-on = "MIT;"
```
If you run `pip-licenses` without any command-line options, all options will be taken from the `pyproject.toml` file.
For instance, if you run `pip-licenses --from=mixed`, the `from` option will be overridden to `mixed`, while all other options will be sourced from `pyproject.toml`.
### More Information
Other, please make sure to execute the `--help` option.
## Dockerfile
You can check the package license used by your app in the isolated Docker environment.
```bash
# Clone this repository to local
$ git clone https://github.com/raimon49/pip-licenses.git
$ cd pip-licenses
# Create your app's requirements.txt file
# Other ways, pip freeze > docker/requirements.txt
$ echo "Flask" > docker/requirements.txt
# Build docker image
$ docker build . -t myapp-licenses
# Check the package license in container
$ docker run --rm myapp-licenses
Name Version License
Click 7.0 BSD License
Flask 1.0.2 BSD License
Jinja2 2.10 BSD License
MarkupSafe 1.1.1 BSD License
Werkzeug 0.15.2 BSD License
itsdangerous 1.1.0 BSD License
# Check with options
$ docker run --rm myapp-licenses --summary
Count License
4 BSD
2 BSD-3-Clause
# When you need help
$ docker run --rm myapp-licenses --help
```
**Note:** This Docker image can not check package licenses with C and C ++ Extensions. It only works with pure Python package dependencies.
If you want to resolve build environment issues, try using not slim image and more.
```diff

## About UnicodeEncodeError
If a `UnicodeEncodeError` occurs, check your environment variables `LANG` and `LC_TYPE`. Additionally, you can set `PYTHONIOENCODING` to override the encoding used for `stdout`.
Often occurs in isolated environments such as Docker and tox.

If you want to use it with Python 3.7, install pip-licenses 3.x.\n\n```bash\n# Using old version for the Python 3.7 environment\n$ pip install 'pip-licenses<4.0'\n```\n\n**Note:** If you are still using Python 2.7, install version less than 2.0. No new features will be provided for version 1.x.\n\n```bash\n$ pip install 'pip-licenses<2.0'\n```\n\n## Usage\n\nExecute the command with your venv (or virtualenv) environment.\n\n```bash\n# Install packages in your venv environment\n(venv) $ pip install Django pip-licenses\n\n# Check the licenses with your venv environment\n(venv) $ pip-licenses\n Name Version License\n Django 2.0.2 BSD\n pytz 2017.3 MIT\n```\n\n## Command-Line Options\n\n### Common options\n\n#### Option: python\n\nBy default, this tools finds the packages from the environment pip-licenses is launched from, by searching in current python's `sys.path` folders. In the case you want to search for packages in an other environment (e.g. if you want to run pip-licenses from its own isolated environment), you can specify a path to a python executable. The packages will be searched for in the given python's `sys.path`, free of pip-licenses dependencies.\n\n```bash\n(venv) $ pip-licenses --with-system | grep pip\n pip 22.3.1 MIT License\n pip-licenses 4.1.0 MIT License\n```\n\n```bash\n(venv) $ pip-licenses --python=</path/to/other/env>/bin/python --with-system | grep pip\n pip 23.0.1 MIT License \n```\n\n#### Option: from\n\nBy default, this tool finds the license from [Trove Classifiers](https://pypi.org/classifiers/) or package Metadata. Some Python packages declare their license only in Trove Classifiers.\n\n(See also): [Set license to MIT in setup.py by alisianoi \u30fb Pull Request #1058 \u30fb pypa/setuptools](https://github.com/pypa/setuptools/pull/1058), [PEP 314\\#License](https://www.python.org/dev/peps/pep-0314/#license)\n\nFor example, even if you check with the `pip show` command, the license is displayed as `UNKNOWN`.\n\n```bash\n(venv) $ pip show setuptools\nName: setuptools\nVersion: 38.5.0\nSummary: Easily download, build, install, upgrade, and uninstall Python packages\nHome-page: https://github.com/pypa/setuptools\nAuthor: Python Packaging Authority\nAuthor-email: distutils-sig@python.org\nLicense: UNKNOWN\n```\n\nThe mixed mode (`--from=mixed`) of this tool works well and looks for licenses.\n\n```bash\n(venv) $ pip-licenses --from=mixed --with-system | grep setuptools\n setuptools 38.5.0 MIT License\n```\n\nIn mixed mode, it first tries to look for licenses in the Trove Classifiers. When not found in the Trove Classifiers, the license declared in Metadata is displayed.\n\nIf you want to look only in metadata, use `--from=meta`. If you want to look only in Trove Classifiers, use `--from=classifier`.\n\nTo list license information from both metadata and classifier, use `--from=all`.\n\n**Note:** If neither can find license information, please check with the `with-authors` and `with-urls` options and contact the software author.\n\n* The `m` keyword is prepared as alias of `meta`.\n* The `c` keyword is prepared as alias of `classifier`.\n* The `mix` keyword is prepared as alias of `mixed`.\n * Default behavior in this tool\n\n#### Option: order\n\nBy default, it is ordered by package name.\n\nIf you give arguments to the `--order` option, you can output in other sorted order.\n\n```bash\n(venv) $ pip-licenses --order=license\n```\n\n#### Option: format\n\nBy default, it is output to the `plain` format.\n\n##### Markdown\n\nWhen executed with the `--format=markdown` option, you can output list in markdown format. The `m` `md` keyword is prepared as alias of `markdown`.\n\n```bash\n(venv) $ pip-licenses --format=markdown\n| Name | Version | License |\n|--------|---------|---------|\n| Django | 2.0.2 | BSD |\n| pytz | 2017.3 | MIT |\n```\n\nWhen inserted in a markdown document, it is rendered as follows:\n\n| Name | Version | License |\n|--------|---------|---------|\n| Django | 2.0.2 | BSD |\n| pytz | 2017.3 | MIT |\n\n##### reST\n\nWhen executed with the `--format=rst` option, you can output list in \"[Grid tables](http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#grid-tables)\" of reStructuredText format. The `r` `rest` keyword is prepared as alias of `rst`.\n\n```bash\n(venv) $ pip-licenses --format=rst\n+--------+---------+---------+\n| Name | Version | License |\n+--------+---------+---------+\n| Django | 2.0.2 | BSD |\n+--------+---------+---------+\n| pytz | 2017.3 | MIT |\n+--------+---------+---------+\n```\n\n##### Confluence\n\nWhen executed with the `--format=confluence` option, you can output list in [Confluence (or JIRA) Wiki markup](https://confluence.atlassian.com/doc/confluence-wiki-markup-251003035.html#ConfluenceWikiMarkup-Tables) format. The `c` keyword is prepared as alias of `confluence`.\n\n```bash\n(venv) $ pip-licenses --format=confluence\n| Name | Version | License |\n| Django | 2.0.2 | BSD |\n| pytz | 2017.3 | MIT |\n```\n\n##### HTML\n\nWhen executed with the `--format=html` option, you can output list in HTML table format. The `h` keyword is prepared as alias of `html`.\n\n```bash\n(venv) $ pip-licenses --format=html\n<table>\n <tr>\n <th>Name</th>\n <th>Version</th>\n <th>License</th>\n </tr>\n <tr>\n <td>Django</td>\n <td>2.0.2</td>\n <td>BSD</td>\n </tr>\n <tr>\n <td>pytz</td>\n <td>2017.3</td>\n <td>MIT</td>\n </tr>\n</table>\n```\n\n##### JSON\n\nWhen executed with the `--format=json` option, you can output list in JSON format easily allowing post-processing. The `j` keyword is prepared as alias of `json`.\n\n```json\n[\n {\n \"Author\": \"Django Software Foundation\",\n \"License\": \"BSD\",\n \"Name\": \"Django\",\n \"URL\": \"https://www.djangoproject.com/\",\n \"Version\": \"2.0.2\"\n },\n {\n \"Author\": \"Stuart Bishop\",\n \"License\": \"MIT\",\n \"Name\": \"pytz\",\n \"URL\": \"http://pythonhosted.org/pytz\",\n \"Version\": \"2017.3\"\n }\n]\n```\n\n##### JSON LicenseFinder\n\nWhen executed with the `--format=json-license-finder` option, you can output list in JSON format that is identical to [LicenseFinder](https://github.com/pivotal/LicenseFinder). The `jlf` keyword is prepared as alias of `jlf`.\nThis makes pip-licenses a drop-in replacement for LicenseFinder.\n\n```json\n[\n {\n \"licenses\": [\"BSD\"],\n \"name\": \"Django\",\n \"version\": \"2.0.2\"\n },\n {\n \"licenses\": [\"MIT\"],\n \"name\": \"pytz\",\n \"version\": \"2017.3\"\n }\n]\n\n```\n\n##### CSV\n\nWhen executed with the `--format=csv` option, you can output list in quoted CSV format. Useful when you want to copy/paste the output to an Excel sheet.\n\n```bash\n(venv) $ pip-licenses --format=csv\n\"Name\",\"Version\",\"License\"\n\"Django\",\"2.0.2\",\"BSD\"\n\"pytz\",\"2017.3\",\"MIT\"\n```\n\n##### Plain Vertical\n\nWhen executed with the `--format=plain-vertical` option, you can output a simple plain vertical output that is similar to Angular CLI's\n[--extractLicenses flag](https://angular.io/cli/build#options). This format minimizes rightward drift.\n\n```bash\n(venv) $ pip-licenses --format=plain-vertical --with-license-file --no-license-path\npytest\n5.3.4\nMIT license\nThe MIT License (MIT)\n\nCopyright (c) 2004-2020 Holger Krekel and others\n\nPermission is hereby granted, free of charge, to any person obtaining a copy of\nthis software and associated documentation files (the \"Software\"), to deal in\nthe Software without restriction, including without limitation the rights to\nuse, copy, modify, merge, publish, distribute, sublicense, and/or sell copies\nof the Software, and to permit persons to whom the Software is furnished to do\nso, subject to the following conditions:\n\nThe above copyright notice and this permission notice shall be included in all\ncopies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR\nIMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,\nFITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE\nAUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER\nLIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM,\nOUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE\nSOFTWARE.\n```\n\n#### Option: summary\n\nWhen executed with the `--summary` option, you can output a summary of each license.\n\n```bash\n(venv) $ pip-licenses --summary --from=classifier --with-system\n Count License\n 2 BSD License\n 4 MIT License\n```\n\n**Note:** When using this option, only `--order=count` or `--order=license` has an effect for the `--order` option. And using `--with-authors` and `--with-urls` will be ignored.\n\n#### Option: output\\-file\n\nWhen executed with the `--output-file` option, write the result to the path specified by the argument.\n\n```\n(venv) $ pip-licenses --format=rst --output-file=/tmp/output.rst\ncreated path: /tmp/output.rst\n```\n\n#### Option: ignore-packages\n\nWhen executed with the `--ignore-packages` option, ignore the package specified by argument from list output.\n\n```bash\n(venv) $ pip-licenses --ignore-packages django\n Name Version License\n pytz 2017.3 MIT\n```\n\nPackage names of arguments can be separated by spaces.\n\n```bash\n(venv) $ pip-licenses --with-system --ignore-packages django pip pip-licenses\n Name Version License\n prettytable 3.5.0 BSD License\n pytz 2017.3 MIT\n setuptools 38.5.0 UNKNOWN\n wcwidth 0.2.5 MIT License\n```\n\nPackages can also be specified with a version, only ignoring that specific version.\n\n```bash\n(venv) $ pip-licenses --with-system --ignore-packages django pytz:2017.3\n Name Version License\n prettytable 3.5.0 BSD License\n setuptools 38.5.0 UNKNOWN\n wcwidth 0.2.5 MIT License\n```\n\n#### Option: packages\n\nWhen executed with the `packages` option, look at the package specified by argument from list output.\n\n```bash\n(venv) $ pip-licenses --packages django\n Name Version License\n Django 2.0.2 BSD\n```\n\nPackage names of arguments can be separated by spaces.\n\n```bash\n(venv) $ pip-licenses --with-system --packages prettytable pytz\n Name Version License\n prettytable 3.5.0 BSD License\n pytz 2017.3 MIT\n```\n\n### Format options\n\n#### Option: with-system\n\nBy default, system packages such as `pip` and `setuptools` are ignored.\n\nAnd `pip-licenses` and the implicit dependency `prettytable` and `wcwidth` will also be ignored.\n\nIf you want to output all including system package, use the `--with-system` option.\n\n```bash\n(venv) $ pip-licenses --with-system\n Name Version License\n Django 2.0.2 BSD\n pip 9.0.1 MIT\n pip-licenses 1.0.0 MIT License\n prettytable 3.5.0 BSD License\n pytz 2017.3 MIT\n setuptools 38.5.0 UNKNOWN\n wcwidth 0.2.5 MIT License\n```\n\n#### Option: with-authors\n\nWhen executed with the `--with-authors` option, output with author of the package.\n\n```bash\n(venv) $ pip-licenses --with-authors\n Name Version License Author\n Django 2.0.2 BSD Django Software Foundation\n pytz 2017.3 MIT Stuart Bishop\n```\n\n#### Option: with-maintainers\n\nWhen executed with the `--with-maintainers` option, output with maintainer of the package.\n\n**Note:** This option is available for users who want information about the maintainer as well as the author. See [#144](https://github.com/raimon49/pip-licenses/issues/144)\n\n#### Option: with-urls\n\nFor packages without Metadata, the license is output as `UNKNOWN`. To get more package information, use the `--with-urls` option.\n\n```bash\n(venv) $ pip-licenses --with-urls\n Name Version License URL\n Django 2.0.2 BSD https://www.djangoproject.com/\n pytz 2017.3 MIT http://pythonhosted.org/pytz\n```\n\n#### Option: with-description\n\nWhen executed with the `--with-description` option, output with short description of the package.\n\n```bash\n(venv) $ pip-licenses --with-description\n Name Version License Description\n Django 2.0.2 BSD A high-level Python Web framework that encourages rapid development and clean, pragmatic design.\n pytz 2017.3 MIT World timezone definitions, modern and historical\n```\n\n#### Option: no-version\n\nWhen executed with the `--no-version` option, output without the version number.\n\n```bash\n(venv) $ pip-licenses --no-version\n Name License\n Django BSD\n pytz MIT\n```\n\n#### Option: with-license-file\n\nWhen executed with the `--with-license-file` option, output the location of the package's license file on disk and the full contents of that file. Due to the length of these fields, this option is best paired with `--format=json`.\n\nIf you also want to output the file `NOTICE` distributed under Apache License etc., specify the `--with-notice-file` option additionally.\n\n**Note:** If you want to keep the license file path secret, specify `--no-license-path` option together.\n\n#### Option: filter\\-strings\n\nSome package data contains Unicode characters which might cause problems for certain output formats (in particular ReST tables). If this filter is enabled, all characters which cannot be encoded with a given code page (see `--filter-code-page`) will be removed from any input strings (e.g. package name, description).\n\n#### Option: filter\\-code\\-page\n\nIf the input strings are filtered (see `--filter-strings`), you can specify the applied code page (default `latin-1`). A list of all available code pages can be found [codecs module document](https://docs.python.org/3/library/codecs.html#standard-encodings).\n\n\n### Verify options\n\n#### Option: fail\\-on\n\nFail (exit with code 1) on the first occurrence of the licenses of the semicolon-separated list. The license name\nmatching is case-insensitive.\n\nIf `--from=all`, the option will apply to the metadata license field.\n\n```bash\n(venv) $ pip-licenses --fail-on=\"MIT License;BSD License\"\n```\n**Note:** Packages with multiple licenses will fail if at least one license is included in the fail-on list. For example:\n```\n# keyring library has 2 licenses\n$ pip-licenses --package keyring\n Name Version License\n keyring 23.0.1 MIT License; Python Software Foundation License\n\n# If just \"Python Software Foundation License\" is specified, it will fail.\n$ pip-licenses --package keyring --fail-on=\"Python Software Foundation License;\"\n$ echo $?\n1\n\n# Matching is case-insensitive. Following check will fail:\n$ pip-licenses --fail-on=\"mit license\"\n```\n\n#### Option: allow\\-only\n\nFail (exit with code 1) if none of the package licenses are in the semicolon-separated list. The license name\nmatching is case-insensitive.\n\nIf `--from=all`, the option will apply to the metadata license field.\n\n```bash\n(venv) $ pip-licenses --allow-only=\"MIT License;BSD License\"\n```\n**Note:** Packages with multiple licenses will only be allowed if at least one license is included in the allow-only list. For example:\n```\n# keyring library has 2 licenses\n$ pip-licenses --package keyring\n Name Version License\n keyring 23.0.1 MIT License; Python Software Foundation License\n\n# One or both licenses must be specified (order and case does not matter). Following checks will pass:\n$ pip-licenses --package keyring --allow-only=\"MIT License\"\n$ pip-licenses --package keyring --allow-only=\"mit License\"\n$ pip-licenses --package keyring --allow-only=\"BSD License;MIT License\"\n$ pip-licenses --package keyring --allow-only=\"Python Software Foundation License\"\n$ pip-licenses --package keyring --allow-only=\"Python Software Foundation License;MIT License\"\n\n# If none of the license in the allow list match, the check will fail.\n$ pip-licenses --package keyring --allow-only=\"BSD License\"\n$ echo $?\n1\n```\n\n#### Option: partial\\-match\n\nIf set, enables partial (substring) matching for `--fail-on` or `--allow-only`. Default is unset (False).\n\nUsage:\n\n```bash\n(venv) $ pip-licenses --partial-match --allow-only=\"MIT License;BSD License\"\n(venv) $ pip-licenses --partial-match --fail-on=\"MIT License;BSD License\"\n\n```\n\n**Note:** Semantics are the same as with `--fail-on` or `--allow-only`. This only enables substring matching.\n```\n# keyring library has 2 licenses\n$ pip-licenses --package keyring\n Name Version License\n keyring 23.0.1 MIT License; Python Software Foundation License\n\n# One or both licenses must be specified (order and case does not matter). Following checks will pass:\n$ pip-licenses --package keyring --allow-only=\"MIT License\"\n$ pip-licenses --package keyring --allow-only=\"mit License\"\n$ pip-licenses --package keyring --allow-only=\"BSD License;MIT License\"\n$ pip-licenses --package keyring --allow-only=\"Python Software Foundation License\"\n$ pip-licenses --package keyring --allow-only=\"Python Software Foundation License;MIT License\"\n\n# These won't pass, as they're not a full match against one of the licenses\n$ pip-licenses --package keyring --allow-only=\"MIT\"\n$ echo $?\n1\n$ pip-licenses --package keyring --allow-only=\"mit\"\n$ echo $?\n1\n\n# with --partial-match, they pass\n$ pip-licenses --package keyring --partial-match --allow-only=\"MIT\"\n$ echo $?\n0\n$ pip-licenses --package keyring --partial-match --allow-only=\"mit\"\n$ echo $?\n0\n```\n\n### pyproject.toml support\n\nAll command-line options for `pip-licenses` can be configured using the `pyproject.toml` file under the `[tool.pip-licenses]` section. \nThe `pyproject.toml` file is searched in the directory where the `pip-licenses` script is executed.\nCommand-line options specified during execution will override the corresponding options in `pyproject.toml`.\n\nExample `pyproject.toml` configuration:\n\n```toml\n[tool.pip-licences]\nfrom = \"classifier\"\nignore-packages = [\n \"scipy\"\n]\nfail-on = \"MIT;\"\n```\n\nIf you run `pip-licenses` without any command-line options, all options will be taken from the `pyproject.toml` file. \nFor instance, if you run `pip-licenses --from=mixed`, the `from` option will be overridden to `mixed`, while all other options will be sourced from `pyproject.toml`.\n\n### More Information\n\nOther, please make sure to execute the `--help` option.\n\n## Dockerfile\n\nYou can check the package license used by your app in the isolated Docker environment.\n\n```bash\n# Clone this repository to local\n$ git clone https://github.com/raimon49/pip-licenses.git\n$ cd pip-licenses\n\n# Create your app's requirements.txt file\n# Other ways, pip freeze > docker/requirements.txt\n$ echo \"Flask\" > docker/requirements.txt\n\n# Build docker image\n$ docker build . -t myapp-licenses\n\n# Check the package license in container\n$ docker run --rm myapp-licenses\n Name Version License\n Click 7.0 BSD License\n Flask 1.0.2 BSD License\n Jinja2 2.10 BSD License\n MarkupSafe 1.1.1 BSD License\n Werkzeug 0.15.2 BSD License\n itsdangerous 1.1.0 BSD License\n\n# Check with options\n$ docker run --rm myapp-licenses --summary\n Count License\n 4 BSD\n 2 BSD-3-Clause\n\n# When you need help\n$ docker run --rm myapp-licenses --help\n```\n\n**Note:** This Docker image can not check package licenses with C and C ++ Extensions. It only works with pure Python package dependencies.\n\nIf you want to resolve build environment issues, try using not slim image and more.\n\n```diff\ndiff --git a/Dockerfile b/Dockerfile\nindex bfc4edc..175e968 100644\n--- a/Dockerfile\n+++ b/Dockerfile\n@@ -1,4 +1,4 @@\n-FROM python:3.11-slim-bullseye\n+FROM python:3.11-bullseye\n```\n\n## About UnicodeEncodeError\n\nIf a `UnicodeEncodeError` occurs, check your environment variables `LANG` and `LC_TYPE`. Additionally, you can set `PYTHONIOENCODING` to override the encoding used for `stdout`.\n\nOften occurs in isolated environments such as Docker and tox.\n\nSee useful reports:\n\n* [#35](https://github.com/raimon49/pip-licenses/issues/35)\n* [#45](https://github.com/raimon49/pip-licenses/issues/45)\n\n## License\n\n[MIT License](https://github.com/raimon49/pip-licenses/blob/master/LICENSE)\n\n### Dependencies\n\n* [prettytable](https://pypi.org/project/prettytable/) by Luke Maurits and maintainer of fork version Jazzband team under the BSD-3-Clause License\n * **Note:** This package implicitly requires [wcwidth](https://pypi.org/project/wcwidth/).\n\n* [tomli](https://pypi.org/project/tomli/) by Taneli Hukkinen under the MIT License\n\n`pip-licenses` has been implemented in the policy to minimize the dependence on external package.\n\n## Uninstallation\n\nUninstall package and dependent package with `pip` command.\n\n```bash\n$ pip uninstall pip-licenses prettytable wcwidth\n```\n\n## Contributing\n\nSee [contribution guidelines](https://github.com/raimon49/pip-licenses/blob/master/CONTRIBUTING.md).\n\n## CHANGELOG\n\n### 5.0.0\n\n* Dropped support Python 3.8\n* Clarified support for Python 3.12\n* Migration pyproject.toml about this package\n* Breaking changes\n * Implicitly depends on tomli library since version 4.5.0\n\n### 4.5.1\n\n* Fixes \"tomli\" to be output only with `--with-system` option\n\n### 4.5.0\n\n* Implement new feature pyproject.toml support\n\n### 4.4.0\n\n* Implement new option `--partial-match`\n\n### 4.3.4\n\n* Maintain to pass test with wcwidth>=0.2.10\n\n### 4.3.3\n\n* Always terminate `--allow-only` and `--fail-on` messages with a newline\n* Always terminate files created with `--output-file` with a newline\n\n### 4.3.2\n\n* Better handling extracting URLs from `Project-URL`\n\n### 4.3.1\n\n* Fix to treat package names as normalized as in [PEP 503](https://peps.python.org/pep-0503/) with `--packages` and `--ignore-packages` option\n\n### 4.3.0\n\n* Implement new option `--no-version`\n\n### 4.2.0\n\n* Implement new option `--with-maintainers`\n* Implement new option `--python`\n* Allow version spec in `--ignore-packages` parameters\n* When the `Author` field is `UNKNOWN`, the output is automatically completed from `Author-email`\n* When the `home-page` field is `UNKNOWN`, the output is automatically completed from `Project-URL`\n\n### 4.1.0\n\n* Support case-insensitive license name matching around `--fail-on` and `--allow-only` parameters\n\n### 4.0.3\n\n* Escape unicode output (to e.g. `{`) in the html output\n\n### 4.0.2\n\n* Add type annotations and code formatter\n\n### 4.0.1\n\n* Fix \"pip-licenses\" is missing in output of `pip-licenses --with-system` option\n\n### 4.0.0\n\n* Support for Python 3.11\n* Dropped support Python 3.7\n* Migrate Docker base image from Alpine to Debian 11-slim\n* Breaking changes\n * Does not work with PTable and depends on prettytable\n * Depend on importlib\\_metadata rather than pip\n\n### 3.5.5\n\n* Search for path defined in [PEP 639](https://peps.python.org/pep-0639/) with `--with-license-file` option\n* Dropped support Python 3.6\n\n### 3.5.4\n\n* Skip directories when detecting license files\n\n### 3.5.3\n\n* Support pip 21.3 or later\n\n### 3.5.2\n\n* Ignore spaces around `--fail-on` and `--allow-only` parameters\n\n### 3.5.1\n\n* Fix the order in which multiple licenses are output\n\n### 3.5.0\n\n* Handle multiple licenses better with options `--fail-on` and `--allow-only`\n* Small change in output method for multiple licenses, change the separator from comma to semicolon\n * Up to 3.4.0: `Python Software Foundation License, MIT License`\n * 3.5.0 or later: `Python Software Foundation License;
