A tool to quickly create sweet PDF files from text files.
Project description
PDF Confectionary :cupcake:
Do you work in the NLP domain and find that your end users/clients are not thrilled by receiving a ton of .txt files with your amazing results? Look no further; you are at the right place!
PDF Confectionary is a tool for quickly creating templated PDFs from text files using FPDF2. Create some sweet PDFs.
About
The primary focus of this repo is to provide a simple, easy to use, and extensible PDF creation tool. The initial use case for this project was to convert transcribed speech to a PDF for reading & review, such as in the vid2cleantxt project. Relevant features in PDF Confectionary include:
- Automatic paragraph separation
- TOC generation & links to TOC entries on each page (click on footer)
- Keyword extraction for each txt file
PDF Confectionary was initially designed as a command-line tool, but it can also be used as an installable Python module.
Installation
Requirements
- Requirements are listed in the requirements.txt file.
- the primary requirements are: FPDF2, textsplit, and clean-text.
Package Installation
The package can be installed using pip:
pip install confectionary
To install as a python package without pip, run:
git clone <https://github.com/pszemraj/confectionary.git>
cd confectionary
pip install .
Usage
There are two ways to use PDF Confectionary:
-
command line, via
python confectionary/text2pdf.py
-
as a python module, via the functions located in the
confectionary.text2pdf
module. Thedir_to_pdf
function provides analogous functionality to the above command line tool.
This will create one pdf from all txt files in the input directory and save it to the output directory. Add the -r
switch (or recurse=True
in function) to load files recursively.
Command Line Usage
- call
python confectionary/text2pdf.py -i /path/to/input/dir -o /path/to/output/dir
to create a pdf from all txt files in the input directory and save it to the output directory:
python confectionary/text2pdf.py -i "./example/text-files" -o "./example/outputs"
- console output is below (in the next section), the result file is in the output directory
example\outputs
. - additional options can be found in the
text2pdf.py
file or by passing the-h
switch.
Basic Usage within Python
- three basic functions are available in
confectionary.text2pdf
:dir_to_pdf
,file_to_pdf
, andstr_to_pdf
:dir_to_pdf
takes a directory path and creates a pdf from all txt files in the directory.file_to_pdf
takes a file path and creates a pdf from the file.str_to_pdf
takes a string and creates a pdf from the string.
Details on the function arguments can be found in the relevant function docstrings (or call help()
). To replicate the above command line example, run:
python
import confectionary
confectionary.text2pdf.dir_to_pdf("./example/text-files", "./example/outputs", key_phrase="test")
The resulting output is in example\outputs
:
3 files found matching extension .txt
# entries is 3, < title thresh 39
will use one page for TOC

- see the
dir_to_pdf
docstring for more details.
Note
- The word2vec model is quite big, 3.7GB. If it doesn't exist, it will be downloaded, and the model will be saved to the
./models
directory. - The word2vec model is not required for the text2pdf tool and can be disabled by setting the
do_paragraph_splitting
parameter toFalse
or in command line mode, by adding the--no-split
switch.
TODO list
- convert the text2pdf.py script to a module/function
- publish to PyPI
- add alternate, smaller, word2vec models for splitting paragraphs
- improve TOC calculation beyond a simple title threshold
- Add a basic notebook demo
