### Installation with pipenv

Source: https://palewi.re/docs/savepagenow

The package can be installed from the Python Package Index with one of Python’s installation tools. Here’s an example with `pipenv`.

```bash
pipenv install savepagenow

```

--------------------------------

### Develop CLI installation

Source: https://palewi.re/docs/savepagenow

The command-line interface is implemented using Click and setuptools. To install it locally for development inside your virtual environment, run the following installation command, as prescribed by the Click documentation.

```bash
pip install --editable .

```

--------------------------------

### Command-line usage

Source: https://palewi.re/docs/savepagenow

The Python library is also installed as a command-line interface. You can run it from your terminal like so:

```bash
savepagenow https://example.com/

```

--------------------------------

### CLI Usage Help

Source: https://palewi.re/docs/savepagenow

The command has the same options as the Python API.

```bash
Usage: savepagenow [OPTIONS] URL

  Archive the provided URL using archive.org's Wayback Machine.

  Raises a CachedPage exception if archive.org declines to conduct a new
  capture and returns a previous snapshot instead.

Options:
  -ua, --user-agent TEXT  User-Agent header for the web request
  -c, --accept-cache      Accept and return cached URL
  -a, --authenticate      Allows you to run saves with authentication
  --help                  Show this message and exit.

```

--------------------------------

### Customize user agent from command line

Source: https://palewi.re/docs/savepagenow

And here’s how to do it from the command line:

```bash
savepagenow http://www.example.com/ --user-agent "my user agent here"

```

--------------------------------

### Import library

Source: https://palewi.re/docs/savepagenow

First import the library into your Python code.

```python
import savepagenow

```

--------------------------------

### Customize user agent in Python

Source: https://palewi.re/docs/savepagenow

Here’s how to do it in Python:

```python
savepagenow.capture("http://www.example.com/", user_agent="my user agent here")

```

--------------------------------

### Handle capture or cache result

Source: https://palewi.re/docs/savepagenow

There’s no accounting for taste but you could craft a line to handle that command like so:

```python
url, captured = savepagenow.capture_or_cache("http://www.example.com/")

```

--------------------------------

### Authenticated capture

Source: https://palewi.re/docs/savepagenow

Authenticated requests are allowed 6 captures per minute. To take advantage of this, you must register an account with archive.org and set your API credentials to the local environment variables `SAVEPAGENOW_ACCESS_KEY` and `SAVEPAGENOW_SECRET_KEY`. Then you can run `capture()` with the authenticate flag set to true like so:

```python
savepagenow.capture(url, authenticate=True)

```

--------------------------------

### Capture or cache method

Source: https://palewi.re/docs/savepagenow

You can craft your code to catch that exception yourself, or use the built-in `capture_or_cache` method, which will return the URL provided by archive.org along with a boolean indicating if it is a fresh capture (True) or from the cache (False).

```python
savepagenow.capture_or_cache("http://www.example.com/")
("https://web.archive.org/web/20161019062832/http://www.example.com/", True)
savepagenow.capture_or_cache("http://www.example.com/")
("https://web.archive.org/web/20161019062832/http://www.example.com/", False)

```

--------------------------------

### Print archive URL

Source: https://palewi.re/docs/savepagenow

See where it’s stored.

```python
print(archive_url)

```

--------------------------------

### Capture a URL

Source: https://palewi.re/docs/savepagenow

Capture a URL.

```python
archive_url = savepagenow.capture("http://www.example.com/")

```

--------------------------------

### Cached pages exception handling

Source: https://palewi.re/docs/savepagenow

If a URL has been recently cached, archive.org may return the URL to that page rather than conduct a new capture. When that happens, the `capture` method will raise a `CachedPage` exception. This is likely happen if you request the same URL twice within a few seconds.

```python
savepagenow.capture("http://www.example.com/")
'https://web.archive.org/web/20161019062637/http://www.example.com/'
savepagenow.capture("http://www.example.com/")
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "savepagenow/__init__.py", line 36, in capture
      archive_url
savepagenow.exceptions.CachedPage: archive.org returned a cached version of this page: https://web.archive.org/web/20161019062637/http://www.example.com/

```
