Post Processor Workbench
ppwb is a set of tools used in post-processing, the final stage of ebook production.
The workbench is a web front-end written in PHP that performs a variety
of post-processing activities by calling out to external programs.
It consists of a user-visible page (index.php) with links to programs for
text analysis (see pptext.php), HTML analysis (see pphtml.php),
"smart quote" processing (see ppsmq.php) and a file compare tool
(see ppcomp.php).
The following two external tools need to be installed in directories under
bin/:
It's recommended that you clone those repos into bin/ directly:
cd bin
git clone https://github.com/DistributedProofreaders/pptext.git
git clone https://github.com/DistributedProofreaders/pphtml.git
git clone https://github.com/DistributedProofreaders/ppcomp.gitSee the individual tools' README.md for their prerequisites.
For ppcomp to work, dwdiff needs to be installed as well.
Python environment
The external python programs require various python libraries to be installed
in order to work. Consult with each of the tools' requirements.txt files
for more details. These can be installed in the system's python3 installation
or in a virtualenv dedicated for ppwb.
If using a virtualenv, you will need to create a python proxy script to initialize the environment. For example:
#!/bin/bash
VENV=/path/to/virtualenv/basedir/
source $VENV/bin/activate
python $*Make this script executable and set it as your $python_runner in config.php.
Ensure that the web server can access the virtualenv. virtualenvs created
in ~/.local may need to have the permissions updated (o+x) to allow the
web server sufficient permissions.
