# INSTALLATION

The latest version of this module (along with any dependencies) can be installed from [CPAN](https://www.cpan.org) with the `cpan` tool that is included with Perl:

```
cpan Catalyst::View::Wkhtmltopdf
```

You can also extract the distribution archive and install this module (along with any dependencies):

```
cpan .
```

You can also install this module manually using the following commands:

```
perl Makefile.PL
make
make test
make install
```

If you are working with the source repository, then it may not have a `Makefile.PL` file.  But you can use the [Dist::Zilla](https://dzil.org/) tool in anger to build and install this module:

```
dzil build
dzil test
dzil install --install-command="cpan ."
```

For more information, see [How to install CPAN modules](https://www.cpan.org/modules/INSTALL.html).

# SECURITY CONSIDERATIONS

## Status of the Wkhtmltopdf Project

**Do not use wkhtmltopdf with untrusted HTML.**

The wkhtmltopdf project [is no longer being maintained](https://wkhtmltopdf.org/status.html),
and the underlying QtWebKit libraries that it uses have been unsupported since 2015.

The [git repository](https://github.com/wkhtmltopdf/wkhtmltopdf) was archived as read-only in 2023.

You should consider migrating to alternative solutions.

## Options

It is assumed that the ["command"](#command) attribute is configured by a trusted source (developer or operator).

The options are sent to wkhtmltopdf via stdin, using the `--read-args-from-stdin` option.
However, any options configured through the web application should be considered untrusted and validated.

## Temporary Files

Temporary HTML and PDF files are saved in ["tmpdir"](#tmpdir).
They may be left in the directory on failure.

When returning a filehandle instead of the PDF content (the default behaviour since v0.6.0), the PDF files are not removed.

A separate process will need to purge files, to prevent them from filling the disk, as well as to remove sensitive information.

# SUPPORT

Only the latest version of this module will be supported.

Future releases may only support Perl versions released in the last ten (10) years.

Please report any bugs or feature requests on the bugtracker website
[https://rt.cpan.org/Public/Dist/Display.html?Name=Catalyst-View-Wkhtmltopdf](https://rt.cpan.org/Public/Dist/Display.html?Name=Catalyst-View-Wkhtmltopdf)

When submitting a bug or request, please include a test-file or a
patch to an existing test-file that illustrates the bug or desired
feature.

## Reporting Security Vulnerabilities

If the bug you are reporting has security implications which make it inappropriate to send to a public issue tracker,
then see `SECURITY.md` for instructions how to report security vulnerabilities.
