Sastadev

Method definitions for use in SASTA

Installation

You can install SASTADEV using pip:

pip install sastadev

Usage

Command line interface

The installation provides an entrypoint sastadev which invokes sastadev.__main__.main()

To lists arguments and options:

sastadev -h

or

python -m sastadev -h

Using as a library

from sastadev.deregularise import correctinflection
result = correctinflection('slaapten')
print(result)
# [('sliepen', 'Overgeneralisation')]

Configuration

The package contains a configuration module sastadev.conf that produces a SastadevConfig object at runtime, called settings.

Using settings values

Example 1 (correct):

from sastadev.conf import settings
def get_dataroot():
    print(settings.DATAROOT)

Example 2 (wrong!):

from sastadev.conf import settings

dataroot = settings.DATAROOT

def get_dataroot():
    print(dataroot)

The key difference is that the code in example 2 evaluates settings.DATAROOT at the moment the code is executed. If settings.DATAROOT changes between the first time the module is loaded and the time it is ran, the first value will be used. This disables configurable settings.

Changing settings

sastadev.conf.settings can be changed at runtime.

⚠️ Changing settings properties changes all code that is executed after the change. Therefore, make sure you set the settings once, and at the beginning of the runtime cycle.
