Latex Everything

Description

Latex Everything can produce PDF documents of everything on your site with
Latex. Or at least everything worth putting into a PDF.

Latex Everything can make PDF documents from individual posts and groups of
posts like categories, tags and custom taxonomy terms. The plugins contains
everything a theme needs to define its own Latex templates, and link to the PDFs
produced.

Installation

1. This plugin requires pdflatex and pdftk installed. You can check for
   these by executing which pdflatex and which pdftk on your host.
2. This plugin also requires you to know at least enough about WordPress to
   cut-and-paste code into your theme.
3. Upload this plugin to the /wp-content/plugins/ directory.
4. Activate the plugin Latex for WordPress through the ‘Plugins’ menu in
   WordPress. Behind the scenes it will generate PDFs for your posts using a
   default Latex template.
5. Link to the PDF version of a post by putting the following into The Loop:
   <a href="”>PDF Version
6. For more advanced usage (user-defined templates and generating Latex
   documents for pages, categories and others) see the Frequently Asked Questions.

FAQ

Why isn’t this working?

If something isn’t working, check this FAQ for a relevant answer. If there isn’t one,
create a new topic in the plugin forum and the author will try to get back to you.

How do I typeset things besides posts?

Go to Settings->Reading. There is a “Latex Everything” section where you can
choose which documents Latex Everything creates. By default only “Single Posts”
option is selected, but you can typeset other post types (including custom ones),
documents containing every post in a category (or other taxonomies), and
documents containing every post of a specific post type.

There are in fact three broad types of document Latex Everything produces:

• single_post — Each document contains a single post (this can be a page or a
  custom post type).
• post_type — Each document contains every post of a particular type (e.g. a
  post, a page, or a custom post type).
• term — Each post contains every post belonging to a specific term (e.g. a
  category, tag, or term in a custom taxonomy).

You need to know what sort of document you’re looking for when getting its url.

When are the PDF files generated?

PDF files that contain a post are updated when it is saved. PDF files are also
generated in bulk after the plugin is activated (this uses WP-Cron, so it takes
a while). If you have a large number of posts and want to generate PDF files for
all of them, deactivate and reactivate the plugin, then wait.

How do I link to the generated documents?

Functions have been provided to link to the generated PDFs.

• the_latex_url( $type, $arg1, [$arg2]) — Prints a direct link to the PDF.
• get_latex_url( $type, $arg1, [$arg2]) — Returns a direct link to the PDF.
• the_latex_permalink( $type, $arg1, [$arg2]) — Prints a link to the
  attachment page.
• get_latex_permalink( $type, $arg1, [$arg2]) — Returns a link to the
  attachment page.
• get_latex_attachment_id( $type, $arg1, [$arg]) — Returns the id of the
  attachment.

The arguments you give depend on the type of PDF document you’re requesting:

For a single_post PDF:

the_latex_url( 'single_post', (int) $post_id )

For a post_type PDF:

the_latex_url( 'post_type', (string) $post_type )

For a term PDF:

the_latex_url( 'term', (int) $term_id, (string) $taxonomy)

Here’s how you would use them in The Loop.

<a href="<?php the_latex_url( 'single_post', get_the_ID() ) ?>">PDF of this post</a>
<a href="<?php the_latex_url( 'post_type', get_post_type() ) ?>">PDF of all posts</a>
<?php foreach( get_the_category() as $category ) : ?>
<a href="<?php the_latex_url( 'term', $category->cat_ID, 'category' ) ?>">PDF of a category</a>
<?php endforeach; ?>

NB: These don’t automatically figure out which post you’re on while in The Loop,
you must always give all of the arguments

If you are going to use these functions in a theme, check they exist and produce
a url first:

<?php if( function_exists('get_latex_url')
          && $latex_url = get_latex_url( 'single_post', get_the_ID() ) ): ?>
<a href="<?php echo $latex_url ?>">PDF</a>
<?php endif; // get_latex_permalink ?>

How do I use my own Latex Templates?

Latex Everything has a default template inside the plugin directory, but it only
falls back on that if it doesn’t find templates in the theme directory. The
plugin searches for templates in the same way that WordPress does.

For a single_post PDF:

latex-single-<post_type>-<post id>.php 
latex-single-<post_type>-<post slug>.php 
latex-single-<post_type>.php 
latex-single.php 
latex.php 

For a post_type PDF:

latex-post-type-<post type name>.pdf
latex-post-type.pdf
latex.pdf

For a term PDF:

latex-term-<taxonomy>-<term id>.pdf
latex-term-<taxonomy>-<term slug>.pdf
latex-term-<taxonomy>.pdf
latex-term.pdf
latex.pdf

Look at default-latex-template.php in the plugin directory for guidance as to
how to make your own.

How can I extend this?

The plugin has been built with the intention of being extensible. The internals
have documentation in comments, and if you want to know how to do something that
isn’t obvious, create a new topic in the plugin forum
and the author will try to get back to you.

  current URL.
