pyigt: Handling interlinear glossed text with Python

This library provides easy access to Interlinear Glossed Text (IGT) according to the Leipzig Glossing Rules, stored as CLDF examples.

Installation

Installing pyigt via pip

pip install pyigt

will install the Python package along with a command line interface igt.

Usage

CLI

$ igt -h
usage: igt [-h] [--log-level LOG_LEVEL] COMMAND ...

optional arguments:
  -h, --help            show this help message and exit
  --log-level LOG_LEVEL
                        log level [ERROR|WARN|INFO|DEBUG] (default: 20)

available commands:
  Run "COMAMND -h" to get help for a specific command.

  COMMAND
    ls                  List IGTs in a CLDF dataset
    stats               Describe the IGTs in a CLDF dataset

The igt ls command allows inspecting IGTs from the commandline, formatted using the four standard lines described in the Leipzig Glossing Rules, where analyzed text and glosses are aligned, e.g.

$ igt ls tests/fixtures/examples.csv 
Example 1:
zəple: ȵike: peji qeʴlotʂuʁɑ,
zəp-le:       ȵi-ke:       pe-ji       qeʴlotʂu-ʁɑ,
earth-DEF:CL  WH-INDEF:CL  become-CSM  in.the.past-LOC

...

Example 5:
zuɑməɸu oʐgutɑ ipiχuɑȵi,
zuɑmə-ɸu      o-ʐgu-tɑ    i-pi-χuɑ-ȵi,
cypress-tree  one-CL-LOC  DIR-hide-because-ADV

IGT corpus at tests/fixtures/examples.csv

igt ls can be chained with other commandline tools such as commands from the csvkit package for filtering:

$ csvgrep -c Primary_Text -m"ȵi"  tests/fixtures/examples.csv | csvgrep -c Gloss -m"ADV" |  igt ls -
Example 5:
zuɑməɸu oʐgutɑ ipiχuɑȵi,
zuɑmə-ɸu      o-ʐgu-tɑ    i-pi-χuɑ-ȵi,
cypress-tree  one-CL-LOC  DIR-hide-because-ADV

Python API

>>> from pyigt import Corpus
>>> corpus = Corpus.from_path('tests/fixtures/cldf-metadata.json')
>>> len(corpus)
>>> len(corpus)
5
>>> for igt in corpus:
...     print(igt)
...     break
... 
zəple: ȵike: peji qeʴlotʂuʁɑ,
zəp-le:       ȵi-ke:       pe-ji       qeʴlotʂu-ʁɑ,
earth-DEF:CL  WH-INDEF:CL  become-CSM  in.the.past-LOC
