libHaru is a library for generating PDF files. libHaru does not support reading and editing of existing PDF files.

Sioyek is a PDF viewer with a focus on textbooks and research papers.

Stapler is a pure Python alternative to PDFtk, a tool for manipulating PDF documents from the command line. It supports

• cherry-picking pages and concatenating them into a new file

• splitting a PDF document into single pages each in its own file

• merging PDF documents with their pages interleaved

• displaying metadata in a PDF document

• displaying the mapping between logical and physical page numbers

This package provides a PDF library capable of splitting, merging, cropping, and transforming PDF files.

Pdfgrep searches in pdf files for strings matching a regular expression. Support some GNU grep options as file name output, page number output, optional case insensitivity, count occurrences, color highlights and search in multiple files.

The zathura-cb plugin adds comic book support to zathura using libarchive.

Impressive is a tool to display PDF files that provides visual effects such as smooth alpha-blended slide transitions. It provides additional tools such as zooming, highlighting an area of the screen, and a tool to navigate the PDF pages.

Xournal is an application for notetaking, sketching, keeping a journal using a stylus.

flyer-composer can be used to prepare one- or two-sided flyers for printing on one sheet of paper.

Imagine you have designed a flyer in A6 format and want to print it using your A4 printer. Of course, you want to print four flyers on each sheet. This is where Flyer Composer steps in, creating a PDF which holds your flyer four times. If you have a second page, Flyer Composer can arrange it the same way - even if the second page is in a separate PDF file.

This package contains only the command line tool. If you like to use the gui, please install the flyer-composer-gui package.

GNU Pem is a simple tool for tracking personal income and expenses. It operates from the command line and it stores its data in a basic text format in your home directory. It can easily print reports of your spending on different expenses via a basic search feature.

This module adds a test to your Perl distribution which checks for pod coverage of all appropriate files.

This module provides a few convenience methods for testing exception based code. It is built with Test::Builder and plays happily with Test::More and friends.

This module provides the most commonly used testing functions, along with automatically turning on strict and warning and gives a bit more fine-grained control over test suites.

Testing code can involve making sure that files are created and deleted as expected. Doing this manually can be error prone, as it's easy to forget a file, or miss that some unexpected file was added. This module simplifies maintaining test directories by tracking their status as they are modified or tested with this API, making it simple to test both individual files, as well as to verify that there are no missing or unknown files.

This module allows you to deliberately hide modules from a program even though they are installed. This is mostly useful for testing modules that have a fallback when a certain dependency module is not installed.

This module is primarily (but not exclusively) for use in test scripts: A block eval configurable and extensible but by default trapping STDOUT, STDERR, warnings, exceptions, would-be exit codes, and return values from boxed blocks of test code.

This module performs various checks on a module's Regexp::Pattern patterns.

Test::Base gives a way to trivially write your own test framework base class. It concentrates on offering reusable data driven patterns, so that you can write tests with a minimum of code.

Check POD files for errors or warnings in a test file, using Pod::Simple to do the heavy lifting.

Test::Fatal is an alternative to the popular Test::Exception. It does much less, but should allow greater flexibility in testing exception-throwing code with about the same amount of typing.

Test::Class::Most provides some more convenience when using Test::Class.

This Perl testing library focuses on testing and working with XPath expressions, most likely in the context of XML document processing.

In situations where you have deep trees of classes, there is a common situation in which you test a module 4 or 5 subclasses down, which should follow the correct behaviour of not just the subclass, but of all the parent classes.

This should be done to ensure that the implementation of a subclass has not somehow ``broken'' the object's behaviour in a more general sense.

Test::Object is a testing package designed to allow you to easily test what you believe is a valid object against the expected behaviour of all of the classes in its inheritance tree in one single call.
