usfm-references 1.0.2

Tools to work with USFM references

USFM-References

A validator for USFM (Unified Standard Format Markers) Biblical references

Requirements

This project requires Python 3.5 or higher

Installation

To install use

pip install usfm-references

Usage

Import one of the methods like

from usfm_references import valid_chapter, valid_chapter_or_intro, valid_usfm, valid_verse

The validation methods all start with valid_. They take a single parameter which should be a string representation of a USMF reference. And they all return a boolean value representing whether the string was valid for the type that the method is validating against.

For example, if you have a string my_reference with a reference of Genesis 1:1, the appropriate USFM reference would be GEN.1.1. You could use the valid_verse method to ensure it is correct like

if valid_verse(my_reference):
    # do stuff

NOTE: These validators match a regular expression pattern. That conforms to the general USFM standard. They do NOT ensure that the USFM actually exists in any particular Bible version.

The currently supported validators are:

• valid_chapter - Ensures the passed string is a valid USFM chapter reference
• valid_chapter_or_intro - Ensures the passed string is either a valid USFM chapter or intro reference
• valid_usfm - Ensures the passed string is a valid USFM reference (can be verse, chapter, or intro)
• valid_verse - Ensures the passed string is a valid USFM verse reference

Development

This project was written with Python 3.6 and is tested in CI with Python 3.5-3.6. One of these must be installed before developing and testing locally.

On a mac you can use the following commands to get up and running.

brew install python3.6

otherwise run

brew upgrade python3.6

to make sure you have an up to date version.

This project uses pipenv for dependency management. Install pipenv

pip3 install pipenv

setup the project env

pipenv install --three --dev

create a .env file using this sample

export PYTHONPATH=`pwd`

now load virtualenv and any .env file

pipenv shell

Running tests

./linters.sh && pytest --cov=usfm_references tests/

Before committing any code

We have a pre-commit hook which should be setup. You can symlink it to run before each commit by changing directory to the repo and running

cd .git/hooks
ln -s ../../pre-commit pre-commit
