Japanese Verb Conjugator

Japanese Verb Conjugator is a Python library for conjugating Japanese verbs. This fork is used to fix some Issues in the usage of the base package. Changes will be recorded in CHANGELOG.md

What forms will Japanese Verb Conjugator conjugate?

Japanese Verb Conjugator conjugates the following verb forms:

• plain form
• polite form
• ~te form
• conditional form
• volitional form
• potential form
• imperative form
• provisional form
• causative form
• passive form

Japanese Verb Conjugator conjugates verbs based on verb class, tense, formality, and polarity parameters. Depending on the conjugation and verb class, the parameters for conjugation methods may vary.

Example

generate_plain_form requires verb class, tense, and formality parameters.

generate_volitional_form requires verb class, tense, and polarity parameters.

Similarily the conjugations of the copula だ/です can be generated.

Installation

Use the package manager pip to install japanese-verb-conjugator-v2. If you want to install japanese-verb-conjugator-v2 and its dependencies in a virtual environment, first create and activiate a virtual environment. If you want to change the virtual environment name to someting other than venv, replace the second venv with your desired name. Use that same name to replace venv in the second command.

python3 -m venv venv
source venv/bin/activate

If you run into trouble, see the Python Virtual Environment tutorial.

Method 1: Pypi

After installing and activating the virtual environment, run the following commands to install japanese-verb-conjugator-v2 and its dependencies.

pip install japanese-verb-conjugator-v2

Note

Pip may display an error during installation that includes the following message.

No matching distribution found for romkan (from JapaneseVerbConjugator)

In this case, run the command pip install romkan and then run pip install japanese-verb-conjugator-v2 again.

You should be good to go! See the Usage section on how to get started using the library.

Method 2: Clone this repository

Go to the directory you want to clone this repository and run the following command.

git clone https://github.com/Bel-Shazzar/JapaneseVerbConjugator.git

To install the Library use the following command

pip install .

To run the library you should install the dependencies in requirements.txt.

pip install -r requirements.txt

You should be good to go! See the Usage section on how to get started using the library.

Usage

Here is an example of how to import the library and use it.

from japverbconj.constants.enumerated_types import Formality, Polarity, Tense, VerbClass
from japverbconj.verb_form_gen import JapaneseVerbFormGenerator as jvfg

jvfg.generate_plain_form("飲む", VerbClass.GODAN, Tense.NONPAST, Polarity.POSITIVE) # returns '飲む'
jvfg.generate_plain_form("飲む", VerbClass.GODAN, Formality.POLITE, Polarity.NEGATIVE) # returns '飲まない'

The library will try to help validate the correctness of the verb by checking for invalid verb lengths, non-Japanese characters, and invalid verb endings. Limitation: this library cannot identify Chinese words with valid Japanese particle endings or nonexistent Japanese verbs.

AHere is an example of how to use the copula generator-

from japverbconj.constants.enumerated_types import Formality, Polarity, Tense, VerbClass
from japverbconj.verb_form_gen import JapaneseVerbFormGenerator as jvfg

jvfg.copula.generate_plain_form(Tense.NONPAST, Polarity.POSITIVE) # returns 'だ'
jvfg.copula.generate_presumptive_form(Tense.NONPAST, Polarity.POSITIVE) # returns 'ではないでしょう'

Tests

The coverage package is used to run the unittests. The configuration is defined in .coveragerc To run the tests, first install the testing requirements

pip install -r test/requirements.txt

Run tests

You can run the tests like this

coverage run -m unittest

View coverage report

After running the tests with coverage you can show the coverage report like this

Alternativly you can generate an html representation like this

coverage html

You can open the html in a browser like this

open htmlcov/index.html
